Dear shareholders,

At Black Hills Corporation, we provide essential energy to 1.34 million electric and natural gas 
customers across eight states. Through a rapidly changing economic and business environment, 
our team is dedicated to delivering the safe, reliable, and cost-effective service our customers and 
communities depend upon every day. 

During 2023, we delivered on our objectives of excellent operational performance and solid 
financial results. We strengthened our financial position and advanced our regulatory, growth and 
resiliency initiatives, setting the stage for future growth.

Reliable. Resilient. Ready.

Our mission of improving life with energy is accomplished every day as a dependable energy 
provider within the communities we live and operate. In 2023, our team delivered more than 7,000 
gigawatt hours of electricity and 95 million dekatherms of natural gas to our utility customers. Our 
resilient team and infrastructure continued to advance our reputation for excellent service as we 
continued to invest in the core needs for the safety and reliability of our systems and successfully 
reduced third-party damages to our natural gas system by nearly 10%.  

In addition, we continued to support customer and community growth and delivered innovative 
solutions for both new and existing customers. This growing demand was reflected through our 
tenth consecutive year of new all-time peaks at Wyoming Electric, representing an increase of 
nearly 70% in peak demand over the last decade.  

Our long-standing commitment to shareholders is also reflected in our 53 consecutive years of 
annual dividend increases and 83 years of uninterrupted dividend payout. This track record of 
sustainable growth through numerous economic cycles, global wars and uncertainties is one of the 
longest in the electric and natural gas utility industry. 

A firm foundation

Being ready for the needs of customers is the result of our customer-focused culture and is 
supported by a solid financial foundation. We delivered on our commitment to strengthen our 
financial position in 2023 as we improved our net debt to total capitalization ratio to 57.3% and 
maintained our BBB+ equivalent credit ratings. Our financial progress in the face of a changing 
economic environment was no easy feat, as we flexed the organization to achieve our objectives, 

www.blackhillscorp.com

including conserving capital and managing expenses while executing on what was necessary to 
deliver on our commitments for our customers and shareholders. 

As we invested in the resiliency and modernization of our infrastructure for the core needs of our 
customers, we continued to develop strategic growth projects. Looking forward, our $4.3 billion 
capital plan for 2024 through 2028 is focused on critical needs for reliability, system integrity, 
electric transmission and new renewable generation.  

We commenced construction of our 260-mile Ready Wyoming electric transmission expansion 
project to stabilize long-term costs for customers, enhance energy market access and capacity,  
and interconnect our electric systems in Cheyenne and our jointly operated South Dakota and 
Wyoming system.  

During the year, we reached the final stages of our integrated resource plan for our jointly operated 
South Dakota and Wyoming system. In 2023, we issued a request for proposals to add 100 
megawatts of utility-owned renewable generation to our system by mid-2026.  

We made great progress on our Clean Energy Plan to support Colorado’s decarbonization goals of 
80% reduction in emissions by 2030 off a 2005 baseline. We issued a request for proposals to add 
400 megawatts of renewable resources by 2029.  

We also successfully served expanding data center and blockchain energy demand, a growing  
and important piece of our business, and a benefit to our other customers and local communities  
in Wyoming.

Looking to the horizon 

Our strategic objectives, including Growth and Financial Performance, Operational Excellence, 
Transformation and People and Culture provide clarity around our goal of growing long-term value 
and serving our stakeholders effectively and efficiently. Our vision, mission and values embodied by 
our unique team and culture are the foundation for our sustainable success and the driving force for 
growing long-term value for our stakeholders. 

www.blackhillscorp.com

Connecting the dots 

Connecting our past success to a vibrant future is based in keeping our customers connected and 
safe. During 2023, we once again delivered reliable service, with all three of our electric utilities in 
the upper tier of reliability as reported by the Edison Electric Institute, with two of our utilities in the 
top quartile of rankings for minimizing customer outage minutes. 

We take pride in connecting to our stakeholders within our communities, cultivating relationships 
and long-term business development. We work closely with our customers and communities, 
developing innovative solutions such as our unique tariffs to serve data centers and large blockchain 
customers, tailoring our service to their needs.  

Our coworkers are also connected within our communities. We are proud to encourage and enable 
our employees to volunteer and engage locally. Our company and employees support a wide range 
of local nonprofit organizations with financial support, volunteer hours, serving on local community 
boards and much more. We were also recognized for our employment of veterans, and we value the 
benefits of their experience and leadership within our organization. 

Our connections and interactions with utility regulators across our states are constructive and 
supportive of the needs of our customers. Over the last year, we negotiated settlements in three 
different rate reviews and continued to manage positive relationships with regulatory bodies  
across our service footprint. Our culture of transparency and proactive communication builds 
long-term trust and education about our goals, demonstrates the prudency of the decisions we are 
making for our customers, and promotes fair and timely recovery of investments and costs required 
to serve customers.

Growing long-term value 

As we execute on our opportunities to sustainably grow long-term value for all our stakeholders, we 
thank you for the confidence and trust you have placed in our company to continue improving lives 
with energy. 

Sincerely,

Steve Mills,  
Chairman, Black Hills Corp. Board of Directors

OUR COMMITMENT TO SUSTAINABILITY 

Our mission of Improving Life with Energy means we must be ready to make tomorrow even better than today. That is why we 
are committed to creating a cleaner energy future which builds upon our responsibility to provide the safe, reliable and cost-
effective energy that improves our customers’ lives. By investing in the success of our employees, continually innovating, 
thoughtfully utilizing resources and keeping people at the core of our decision-making, we are dedicated to the sustainability of 
our Company, communities and planet.   

Environmental, Social and Governance (ESG) Strategy and Oversight 

We are continuously building upon our success of delivering cost-effective energy for customers and strong returns for 
investors by seeking renewable energy growth opportunities, minimizing risk and responding to stakeholders’ evolving 
expectations. ESG and sustainability are inherently connected throughout our business and our ESG management is 
structured accordingly. Our Board oversees ESG, with management leadership from our CEO and executive steering 
committee, our dedicated department and our cross functional sustainability working group.   

Responsibly Reducing Greenhouse Gas Emissions 

We have set challenging, yet realistic, goals for delivering cleaner energy. We've reduced our electric utilities' greenhouse gas 
emissions intensity by one-third since 2005 and have a clear path to achieve our reduction goals of 40% by 2030 and 70% by

Our goals are compared to a 2005 baseline. 
Electric Utilities goals include Scope 1 emissions from electric utility generating units and Scope 3 emissions from purchased 
power for sales.  
Natural Gas Utilities goals include all Scope 1 sources of methane emissions on our distribution system, including fugitive 
emissions from pipeline mains and service lines, meters, transfer stations, system damages and system blow downs.       

We are proud of our sustainability efforts and continue to pursue initiatives to enable the transition to a cleaner energy future, 
including: 

 

 

 

 

Since 2005, we have reduced GHG emissions intensity from our electric utilities by one-third. Additionally, our 
Electric Utilities have reduced nitrogen oxide and sulfur dioxide emissions by more than 75% since 2005. Colorado 
Electric has achieved a nearly 50% reduction in GHG emissions since 2005 and is on track to reach the State of 
Colorado's 80% carbon reduction goal by 2030. 
We completed a hydrogen blending feasibility study for our Cheyenne Prairie natural gas generation facility and are 
now working on a feasibility analysis for a coal to hydrogen project. 
We successfully filed and received approval for Green Forward, a voluntary renewable natural gas (RNG) attribute 
and carbon offset program, expected to provide customers with a cost-effective path to offset up to 100% or more of 
the emissions associated with their own natural gas footprint. 
As we look to the future, our approximately 500 MW of planned battery storage, renewable generation and 
additions,  position us to achieve deeper carbon reductions that also deliver reliable and cost-effective energy to our 
customers. 

We will continue executing our strategy of investing in cost-effective renewables and new technologies to further reduce our 
environmental impact across all states in which we operate, while continuing to deliver safe, reliable and cost effective energy 
to customers.

OUR COMMITMENT TO WILDFIRE SAFETY AND PREVENTION 

We have a long history of delivering safe and reliable energy to our customers. For decades, we have employed a wide variety 
of wildfire mitigation measures and initiatives to support the integrity of our energy delivery systems, while safeguarding our 
facilities and the surrounding environment. These efforts are part of our comprehensive approach to mitigate not only wildfire 
risk, but also a variety of extreme weather events, including ice storms and high winds. We are utilizing a three-pronged 
approach to wildfire mitigation, which includes the following: 

 

 

 

Asset programs like preventative inspection, repair, and maintenance practices, including vegetation 
management, line patrol in the air and on the ground, and pole inspections and replacement. 
Integrity programs and system investments aimed at improving reliability and reducing risk, undergrounding 
electric distribution lines, and applying construction standards that reduce the likelihood of wildfire interactions with 
facilities. 
Operational response utilizing risk-driven decisions including system reconfigurations, daily work activities and 
equipment operation (non-reclosing energized power lines), and fire weather forecasting tools to enhance 
situational awareness and understanding of a potentially hazardous fire area.

EXECUTIVE COMPENSATION 

We have an Executive Compensation Philosophy that establishes the framework our Compensation Committee applies in 
structuring compensation for our executive officers ("Named Executive Officers" or "NEOs"). The components of our executive 
pay program consist of a base salary, a short-term incentive plan, and long-term incentives. Our executive pay program aligns 
the interest of our Named Executive Officers with our stakeholders by tying incentive pay to achievement of performance 
metrics.

*Percentages may differ from above due to rounding. 

The performance measures for our incentive compensation plans are discussed in greater detail on page 27 of the Proxy 
Statement. We also require our executive officers to hold a significant amount of our common stock (between 3 and 6 times 
the base salary) to further align their interests with the interest of our stakeholders.   

Our compensation practices and policies demonstrate the alignment between executive compensation and the interests of our 
stakeholders. Our shareholders share our confidence in our compensation philosophy as reflected by the support of 
shareholders owning 98 percent of the shares who voted to approve our 2022 executive compensation at last year's annual 
meeting.

COMMONLY ASKED QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING PROCESS 

Who is soliciting my proxy? 

The Board of Directors of Black Hills Corporation is soliciting your proxy. 

Where and when is the annual meeting? 

The annual meeting is at 9:30 a.m., local time, April 23, 2024 at Horizon Point, the Company’s corporate headquarters, 7001 
Mount Rushmore Road, Rapid City, South Dakota. 

Who can vote? 

Holders of our common stock as of the close of business on the record date, March 4, 2024, can vote at our annual meeting. 
Each share of our common stock has one vote for Proposals 2, and 3. Related to Proposal 1, Election of Directors, cumulative 
voting is permitted in the election of directors in the same class.  

How do I vote? 

There are three ways to vote by proxy: 

 
 
 

by calling the toll free telephone number on the enclosed proxy; 
by going to the website identified on the enclosed proxy; or 
by returning the enclosed proxy in the envelope provided. 

You may be able to vote by telephone or over the Internet if your shares are held in the name of a bank or broker. If this is the 
case, you will need to follow their instructions. 

What constitutes a quorum? 

Shareholders representing at least 50 percent of our common stock issued and outstanding as of the record date must be 
present at the annual meeting, either in person or by proxy, for there to be a quorum. Abstentions and broker non-votes are 
counted as present for establishing a quorum. A broker non-vote occurs when a broker or other nominee holding shares for a 
beneficial owner does not vote on a particular proposal because the broker or nominee does not have discretionary voting 
power and has not received instructions from the beneficial owner.

The required vote and method of counting votes for the various business matters to be considered at the annual meeting are

accordance with the Board recommendations as set forth below.

This advisory vote is not binding on the Board, but 
the Board will consider the vote results when 
making future executive compensation decisions. 

Is cumulative voting permitted for the election of directors? 

In the election of directors, you may cumulate your vote. Cumulative voting allows you to allocate among the director 
nominees in the same class, as you see fit, the total number of votes equal to the number of director positions to be filled 
multiplied by the number of shares you hold. For example, if you own 100 shares of stock, and there are three directors to be 
elected in a class at the annual meeting, you could allocate 300 “For” votes (three times 100) among as few or as many of the 
three nominees to be voted on at the annual meeting as you choose. 

If you choose to cumulate your votes, you will need to submit a proxy card or a ballot and make an explicit statement of your 
intent to cumulate your votes, either by indicating in writing on the proxy card or by indicating in writing on your ballot when 
voting at the annual meeting. If you hold shares beneficially in street name and wish to cumulate votes, you should contact 
your broker, trustee or nominee.

How will my shares be voted if they are held in a broker’s name? 

If you hold your shares through an account with a bank or broker, the bank or broker may vote your shares on some matters 
even if you do not provide voting instructions. Brokerage firms have the authority under the New York Stock Exchange 
("NYSE") rules to vote shares on certain matters (such as the ratification of auditors) when their customers do not provide 
voting instructions. However, on most other matters when the brokerage firm has not received voting instructions from its 
customers, the brokerage firm cannot vote the shares on that matter and a “broker non-vote” occurs. This means that 
brokers may not vote your shares on the election of directors or the “say on pay” advisory vote if you have not given 
your broker specific instructions as to how to vote. Please be sure to give specific voting instructions to your broker 
so that your vote can be counted. 

What should I do now? 

You should vote your shares by telephone, over the Internet or by returning your signed and dated proxy card in the enclosed 
envelope as soon as possible so that your shares will be represented at the annual meeting. 

Who will count the vote? 

Representatives of our transfer agent, Equiniti Trust Company, will count the votes and serve as judges of the election.  

Who conducts the proxy solicitation and how much will it cost? 

We are asking for your proxy for the annual meeting and will pay all the costs of asking for shareholder proxies. We have hired 
Georgeson LLC to help us send out the proxy materials and ask for proxies. Georgeson LLC’s fee for these services is 
anticipated to be $12,250 plus out-of-pocket expenses. We can ask for proxies through the mail, by telephone or in person. 
We can use our directors, officers and employees to ask for proxies. These people do not receive additional compensation for 
these services. We will reimburse brokers and other custodians, nominees and fiduciaries for their reasonable out-of-pocket 
expenses for forwarding solicitation material to the beneficial owners of our common stock. 

Can I revoke my proxy? 

Yes. You can change your vote in one of four ways at any time before your proxy is used. First, you can enter a new vote by 
telephone or Internet. Second, you can revoke your proxy by written notice. Third, you can send a later dated proxy changing 
your vote. Fourth, you can attend the meeting and vote in person. 

Who should I call with questions? 

If you have questions about the annual meeting, you should call Amy K. Koenig, Vice President - Governance, Corporate 
Secretary and Deputy General Counsel, at (605) 721-1700.

PROPOSAL 1 

ELECTION OF DIRECTORS 

Our Board is nominating four individuals for election as directors at this annual meeting. All of the nominees are currently 
serving as our directors. In accordance with our Bylaws and Article VI of our Articles of Incorporation, members of our Board 
are elected to three classes of staggered terms consisting of three years each, and until their successors are duly elected and 
qualified. At this annual meeting, four directors will be elected to Class III for a term of three years until our annual meeting in 
2027. 

Nominees for director at the annual meeting are Linden R. Evans, Barry M. Granger, Tony A. Jensen, and Steven R. Mills. Our 
Bylaws require a minimum of nine directors. Currently, the Board has set the size of the Board at ten directors.  

If, at the time of the annual meeting, any nominees are unable to stand for election, the Board may designate a substitute or 
reduce the number of directors to no less than nine. In that case, shares represented by proxies may be voted for a substitute 
director nominated by the Board. We do not expect that any nominee will be unavailable or unable to serve. 

The Board and the Governance Committee believe that the combination of the various qualifications, skills and experiences of 
the directors contribute to an effective and well-functioning Board, and that, individually and as a whole, the directors possess 
the necessary qualifications to provide effective oversight of the business and quality advice to the Company’s management. 
Included in each director’s biography below is an assessment of the specific qualifications, attributes, skills and experience 
that have led to the conclusion that each individual should serve as a director in light of our current business and structure. 

The Board recommends a vote FOR the election of the following nominees:

CORPORATE GOVERNANCE 

Corporate Governance Guidelines 

Our Board has adopted “Corporate Governance Guidelines of the Board,” which guide the operation of our Board and assist 
the Board in fulfilling its obligations to shareholders and other constituencies. The guidelines lay the foundation for the Board’s 
responsibilities, operations, leadership, organization and committee matters. The Governance Committee reviews the 
guidelines annually, and the guidelines may be amended at any time, upon recommendation by the Governance Committee 
and approval of the Board. These guidelines can be found in the “Corporate Governance” section of our website 
(https://ir.blackhillscorp.com/corporate-governance/governance-documents). 

Board Leadership Structure 

On May 1, 2020, Steven R. Mills, an independent director, was appointed Chairman of the Board. As Chairman, Mr. Mills 
leads our Board in the performance of its duties by working with the CEO to establish meeting agendas, facilitating board 
meetings and executive sessions, and collaborating with the Board to annually evaluate the performance of the CEO.   

As provided in our Corporate Governance Guidelines, the Board does not have a policy on whether or not the roles of 
Chairman and CEO should be separate or combined. The Governance Committee annually reviews the appropriate leadership 
structure for the Company and recommends a Chairman for Board approval. While our Bylaws and Corporate Governance 
Guidelines do not require that our Chairman and CEO positions be held by separate individuals, the Board believes that 
having separate positions and having an independent director serve as Chairman is the appropriate leadership structure for 
the Company at this time because it allows our CEO to focus on business operations and our Chairman to focus on Board 
governance.  

Risk Oversight  

Our Board oversees an enterprise risk management ("ERM") approach to risk management that supports our operational and 
strategic objectives. It fulfills its oversight responsibilities through receipt of quarterly reports from management regarding 
material risks involving strategic planning and execution, operations, physical and cybersecurity, environmental, social and 
governance ("ESG"), financial, legal, safety, regulatory, and human resources risks. While our full Board retains responsibility 
for risk oversight, it delegates oversight of certain risk considerations to its committees within each of their respective areas of 
responsibility as defined in the charter for each committee. 

Our management is responsible for day-to-day risk management and operates under our ERM program that addresses 
enterprise risks. The ERM program includes practices to identify risks, assess the impact and likelihood of occurrence, and 
develop action plans to prevent the occurrence or mitigate the impact of the risk. The ERM program includes regular reporting 
to our senior management team, quarterly reporting to our Board, and monitoring and testing by the Risk Management, 
Compliance and Internal Audit groups.  

Sustainability Oversight 

We are committed to creating a cleaner energy future that builds upon our responsibility to provide the safe, reliable and 
economic energy that improves our customers' lives. The Board oversees management's execution of our sustainability 
objectives and receives quarterly updates from management regarding sustainability matters. Under the oversight of the 
Board, we published our 2022 Corporate Sustainability Report in the third quarter of 2023. In addition to announcing progress 
toward our goal to reduce electric utility emission intensity 40% by 2030 and 70% by 2040, we provided key strategic updates 
to our plans to achieve net zero emissions by 2035 for our natural gas distribution system. Also in the third quarter of 2023, we 
issued updated Edison Electric Institute and American Gas Association ESG disclosures, Natural Gas Sustainability Initiative 
(NGSI) disclosures, Sustainability Accounting Standards Board (SASB) disclosures, and Task Force on Climate Related 
Financial Disclosure Index disclosures.   

Cyber and Physical Security Oversight 

Our Board retains oversight of cyber and physical security. Our Chief Information Officer provides the Board quarterly reports 
that summarize material security risks and the measures that have been put in place to mitigate the associated risks. These 
reports address a variety of topics including updates on strategic initiatives, industry trends, threat vulnerability assessments, 
and efforts to prevent, detect and respond to internal and external critical threats.

Human Capital Management Oversight 

Primary responsibility for oversight of human capital management rests with our Compensation Committee. As part of its 
oversight, the Committee reviews regular reports from management regarding diversity and inclusion, pay equity, strategic 
workforce planning, talent retention, employee benefits programs, employee engagement, human rights, and company culture. 

Succession Planning Oversight 

Our Board is actively engaged in succession planning for our key executive positions to ensure a strong bench of future 
leaders. To assist the Board, our CEO and our Human Resources team perform talent reviews and discuss succession 
planning and leadership development. Semi-annually, their assessment of senior executive talent, including potential of such 
talent to succeed our CEO or other executive officers, readiness for succession and development opportunities are presented 
to our Board. 

Director Nominees  

The Governance Committee uses a variety of methods for identifying and evaluating nominees for director. The Governance 
Committee regularly assesses the appropriate size of the Board and whether any vacancies on the Board are expected due to 
retirement or otherwise. In the event vacancies are anticipated, or otherwise arise, the Governance Committee considers 
various potential candidates for director. Board candidates are considered based upon various criteria, including diversity of 
gender, race and ethnicity; business, administrative and professional skills or experiences; an understanding of relevant 
industries, technologies and markets; financial literacy; independence status; the ability and willingness to contribute time and 
special competence to Board activities; personal integrity and independent judgment; and a commitment to enhancing 
shareholder value. The Governance Committee considers these and other factors as it deems appropriate, given the needs of 
the Board. Our goal is a diverse, talented, and highly engaged Board, with members whose skills, background and experience 
are complementary and, together, cover the spectrum of areas that impact our business currently and in the future. The 
Governance Committee considers candidates for Board membership suggested by a variety of sources, including current or 
past Board members, the use of third-party executive search firms, members of management, and shareholders. Any 
shareholder may make recommendations for consideration by the Governance Committee for membership on the Board by 
sending a written statement of the qualifications of the recommended individual to the Corporate Secretary. The Committee 
evaluates all director candidates in the same manner using the same criteria regardless of who recommends them. 

Shareholders who intend to nominate persons for election to the Board must provide timely written notice of the nomination in 
accordance with Article I, Section 9 of our Bylaws. Generally, our Corporate Secretary must receive the written notice at our 
executive offices at 7001 Mount Rushmore Road, P.O. Box 1400, Rapid City, South Dakota 57709, not less than 90 days nor 
more than 120 days prior to the anniversary date of the immediately preceding annual meeting of shareholders. For the 2025 
shareholder meeting, those dates are January 23, 2025 and December 24, 2024. The notice must include at a minimum the 
information set forth in Article I, Section 9 of our Bylaws, including the shareholder’s identity, contingent ownership interests, 
description of any agreement made with others acting in concert with respect to the nomination, specific information about the 
nominee and certain representations by the nominee to us. 

Board Independence 

In accordance with NYSE rules, the Board through its Governance Committee, affirmatively determines the independence of 
each director and director nominee in accordance with guidelines it has adopted, which include all elements of independence 
set forth in the NYSE listing standards. These guidelines are contained in our Policy for Director Independence, which can be 
found in the "Corporate Governance" section of our website (https://ir.blackhillscorp.com/corporate-governance/governance-
documents). Based on these standards, the Governance Committee determined that each of the following non-employee 
directors is independent and has no relationship with us, except as a director and shareholder: Barry M. Granger, Tony A. 
Jensen, Kathleen S. McAllister, Steven R. Mills, Robert P. Otto, Scott M. Prochazka, Rebecca B. Roberts, Mark A. Schober, 
and Teresa A. Taylor. In addition, based upon these standards, the Governance Committee determined that Mr. Evans is not 
independent because he is an officer of the Company. 

Director Resignation Policies 

The Corporate Governance Guidelines require members of the Board to submit a letter of resignation for consideration by the 
Board in certain circumstances. The Corporate Governance Guidelines include a plurality plus voting policy. Pursuant to the 
policy, any nominee for election as a director in an uncontested election who receives a greater number of votes “Withheld” 
from his or her election than votes “For” his or her election will promptly tender his or her resignation as a director to the 
Chairman of the Board following certification of the election results. Broker non-votes will not be deemed to be votes “For” or 
“Withheld” from a director’s election for purposes of the policy. The Governance Committee (without the participation of the 
affected director) will consider each resignation tendered under the policy and recommend to the Board whether to accept or 
reject it. The Board will then take the appropriate action on each tendered resignation, taking into account the Governance 
Committee’s recommendation. The Governance Committee in making its recommendation, and the Board in making its 
decision, may consider any factors or other information that it considers appropriate, including the reasons why the 
Governance Committee believes shareholders “Withheld” votes for election from such director and any other circumstances 

13 

PROXY|  PROXY STATEMENT 
 
 
 
 
 
 
 
 
 
 
 
surrounding the “Withheld” votes, any alternatives for curing the underlying cause of the “Withheld” votes, the qualifications of 
the tendering director, his or her past and expected future contributions to us and the Board, and the overall composition of the 
Board, including whether accepting the resignation would cause us to fail to meet any applicable SEC or NYSE requirements. 
The Board will publicly disclose its decision and rationale by filing a Form 8-K with the SEC within 90 days after receipt of the 
tendered resignation. 

The Corporate Governance Guidelines also require members of the Board to tender a letter of resignation in the event of a 
change in professional responsibilities that may directly or indirectly impact that Board member’s ability to fulfill directorship 
obligations. The Board is not obligated to accept that resignation. The Governance Committee will review the affected 
member’s service and qualifications and recommend to the Board the continued appropriateness of Board membership under 
the circumstances.   

Codes of Business Conduct and Ethics 

The Code of Business Conduct and the Code of Ethics that apply to our Chief Executive Officer and Senior Financial Officers 
can be found in the “Corporate Governance” section of our website (https://ir.blackhillscorp.com/corporate-
governance/governance-documents). We intend to disclose any amendments to, or waivers of, the Code of Ethics on our 
website. Please note that none of the information contained on our website is incorporated by reference in this proxy 
statement. 

Certain Relationships and Related Party Transactions  

We recognize related party transactions can present potential or actual conflicts of interest and create the appearance that 
decisions are based on considerations other than the best interests of us and our shareholders. Accordingly, as a general 
matter, it is our preference to avoid related party transactions. Nevertheless, we recognize that there are situations where 
related party transactions may be in, or may not be inconsistent with, the best interests of us and our shareholders, including 
but not limited to situations where we may obtain products or services of a nature, quantity or quality, or on other terms, that 
are not readily available from alternative sources or when we provide products or services to related parties on an arm’s length 
basis on terms comparable to those provided to unrelated third parties or on terms comparable to those provided to 
employees generally.  

Therefore, our Board has adopted a policy for the review of related party transactions. This policy requires directors and 
officers to promptly report to our Vice President - Governance all proposed or existing transactions in which the Company and 
they, or persons related to them, are parties or participants. Our Vice President - Governance presents those transactions to 
our Governance Committee. Our Governance Committee reviews the material facts presented and either approves or 
disapproves entry into the transaction. In reviewing the transaction, the Governance Committee considers the following 
factors, among other factors it deems appropriate: (i) whether the transaction is on terms no less favorable than terms 
generally available to an unaffiliated third party under the same or similar circumstances; (ii) the extent of the related party’s 
interest in the transaction; and (iii) the impact on a director’s independence in the event the related party is a director, an 
immediate family member of a director or an entity in which a director is a partner, shareholder or executive officer. There were 
no reportable related party transactions in 2023. 

Delinquent Section 16(a) Reports 

Based solely upon a review of our records and reports on Forms 3, 4 and 5 filed with the SEC, we believe that during and with 
respect to 2023, all persons subject to the reporting requirements of section 16(a) of the Securities and Exchange Act of 1934, 
as amended, filed the required reports on a timely basis, except for a Form 4 for Mr. Keller related to an August 2023 
transaction that was reported in December of 2023. 

Communications with the Board  

We value the views and input of our shareholders and believe that fostering productive dialogue with our shareholders 
contributes to our long-term success. Shareholders and others interested in communicating directly with the Chairman, with 
the independent directors as a group, or the Board may do so in writing to the Chairman, Black Hills Corporation, 7001 Mount 
Rushmore Road, P.O. Box 1400, Rapid City, South Dakota 57709.

MEETINGS AND COMMITTEES OF THE BOARD 

THE BOARD 

Our Board held eleven meetings during 2023. Each regularly scheduled meeting of the Board includes an executive session of 
only independent directors. We encourage our directors to attend the annual shareholders’ meeting. During 2023, each current 
director attended at least 75 percent of the combined total of Board meetings and Committee meetings on which the director 
served. While not required under our policies, all directors attended the 2023 annual meeting of shareholders. 

COMMITTEES OF THE BOARD 

Our Board has three standing committees to facilitate and assist the Board in the execution of its responsibilities. Those 
standing committees are the Audit Committee, the Compensation Committee and the Governance Committee. Each 
committee operates under a charter, which is available on our website at https://ir.blackhillscorp.com/corporate-
governance/governance-documents and is also available in print to any shareholder who requests it. In addition, our Board 
creates special committees from time to time for specific purposes. Members of the committees are designated by our Board 
upon recommendation of the Governance Committee.

executive officers. The Committee reviewed the independence of Meridian and the individual 
representatives of Meridian who served as consultants to the Committee, in accordance with the 
SEC and NYSE requirements. The Compensation Committee concluded that Meridian was 
independent and Meridian’s performance of services raised no conflict of interest. The 
Committee’s conclusions were based in part on a report that Meridian provided to the 
Committee intended to reveal any potential conflicts of interest and a schedule of the type and 
amount of non-executive compensation services provided by Meridian to the Company. During 
2023, the cost of these non-executive compensation services was less than $25,000. 

Compensation Committee Interlocks. None of our executive officers serve as a member of a board of directors or

DIRECTOR COMPENSATION 

DIRECTOR FEES 

Compensation to our non-employee directors consists of cash retainers for Board members, Committee members, the Board 
Chairman and Committee Chairs. 

In setting non-employee director compensation, the Compensation Committee recommends the form and amount of 
compensation to the Board, which makes the final determination. In considering and recommending the compensation of non-
employee directors, the Compensation Committee considers such factors as it deems appropriate, including historical 
compensation information, level of compensation necessary to attract and retain non-employee directors meeting our desired 
qualifications and market data. We do not pay meeting fees. The Committee did not recommend a change to director 
compensation for 2023. However, in January 2024 the Committee recommended and our Board approved increases to the 
cash retainer, equity compensation, Chairman retainer, and Governance Chair retainer to maintain our board compensation 
level near the median of our peers. The fee structure for director fees in 2023 and the fee structure that will take effect in May 
2024, are as follows:

will vest, if not deferred, at the 2024 annual meeting) and deferred stock units (1,753 shares for Ms. McAllister and Messrs. Granger, 
Mills, and Schober who elected to defer their restricted stock awards until they separate from the board).

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC 
ACCOUNTING FIRM 

The firm of Deloitte & Touche LLP, independent registered public accountants, conducted the audit of Black Hills Corporation 
and its subsidiaries for 2023. Representatives of Deloitte & Touche LLP will be present at our annual meeting and will have the 
opportunity to make a statement, if they desire to do so, and to respond to appropriate questions. 

Our Audit Committee has appointed Deloitte & Touche LLP to perform an audit of our consolidated financial statements and 
those of our subsidiaries for 2024 and to render their reports. In determining whether to recommend to the full Board the 
reappointment of Deloitte & Touche LLP as our independent auditor, the Audit Committee considered the following: 

• 
• 
• 
• 
• 
• 

Technical expertise and knowledge of the Company’s business and industry 
The quality and candor of communications with the Audit Committee 
Deloitte & Touche LLP’s independence 
Public Company Accounting Oversight Board inspection reports on the firm 
Input from management on Deloitte & Touche LLP’s performance, objectivity and professional judgment 
The appropriateness of fees for audit and non-audit services 

The Board recommends ratification of the Audit Committee’s appointment of Deloitte & Touche LLP. The appointment of 
Deloitte & Touche LLP as our independent registered public accounting firm for 2024 will be ratified if the votes cast “For” 
exceed the votes cast “Against.” Abstentions will have no effect on such vote. If shareholder approval for the appointment of 
Deloitte & Touche LLP is not obtained, the Audit Committee will reconsider the appointment. 

The Board recommends a vote FOR ratification of the appointment of Deloitte & Touche LLP 
to serve as our independent registered public accounting firm for 2024.

AUDIT COMMITTEE REPORT 

The Audit Committee assists the Board in fulfilling its oversight responsibilities to shareholders relating to the integrity of the 
Company’s financial statements, the Company’s compliance with legal and regulatory requirements regarding financial reporting, the 
independent auditors’ qualifications and independence, and the performance of the Company’s internal and independent auditors.   

Management has the primary responsibility for the completeness and accuracy of the Company’s financial statements and 
disclosures, the financial reporting process, and the effectiveness of the Company’s internal control over financial reporting.  

Our independent auditors, Deloitte & Touche LLP, are responsible for auditing the Company’s consolidated financial statements and 
expressing an opinion as to whether they are presented fairly, in all material respects, in conformity with accounting principles 
generally accepted in the United States.  

In fulfilling its oversight responsibilities for 2023, the Audit Committee, among other things: 

• 

• 

• 

• 

• 

• 

• 

• 
• 

• 

• 

Reviewed and discussed the audited financial information contained in the Annual Report on Form 10-K with management 
and our independent auditors prior to public release.  
Reviewed and discussed with our independent auditors their judgments as to the quality, not just the acceptability, of our 
critical accounting principles and estimates and all other communications required to be discussed with the Audit 
Committee under generally accepted auditing standards, including the matters required to be discussed by the applicable 
requirements of the Public Company Accounting Oversight Board and the SEC.  
Reviewed and discussed with management, our internal auditors and our independent auditors management’s report on 
internal control over financial reporting, including the significance and status of control deficiencies identified by 
management and the results of remediation efforts undertaken, to determine the effectiveness of internal control over 
financial reporting at December 31, 2023. 
Reviewed with our independent auditors their report on the Company’s internal control over financial reporting at 
December 31, 2023, including the basis for their conclusions.  
Reviewed and pre-approved all audit and non-audit services and fees provided to the Company by our independent 
auditors and considered whether the provision of such non-audit services by our independent auditors is compatible with 
maintaining their independence.  
Discussed with our internal and independent auditors their audit plans, audit scope and identification of audit risks and 
reviewed the results of internal audit examinations. 
Reviewed and discussed the interim financial information contained in each quarterly earnings announcement and 
Quarterly Report on Form 10-Q with management and our independent auditors prior to public release.  
Received and reviewed periodic corporate compliance and financial risk reports, including credit and hedging activity. 
Held private sessions with our independent auditors, Vice President - Internal Audit, Chief Financial Officer and Controller, 
and Chief Compliance Officer.

the Public Company Accounting Oversight Board regarding the independent auditors’ communications with the Committee 
concerning independence and discussed the independence of Deloitte & Touche LLP with them.  
Concluded Deloitte & Touche LLP is independent based upon the above considerations. 

Based upon the reviews and discussions referred to above, the Audit Committee recommended to the Board that our audited 
consolidated financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the 
SEC. The Audit Committee also recommended and the Board reappointed Deloitte & Touche LLP as our independent registered 
public accounting firm for 2024. Shareholders are being asked to ratify that selection at the 2024 Annual Meeting.

PROPOSAL 3  ADVISORY VOTE ON OUR EXECUTIVE COMPENSATION 

We are providing shareholders with an annual advisory, non-binding vote on the executive compensation of our Named 
Executive Officers (commonly referred to as “say on pay”). Accordingly, shareholders will vote on approval of the following 
resolution: 

RESOLVED, that the shareholders approve, on an advisory basis, the compensation of our Named 

Executive Officers as disclosed in the Compensation Discussion and Analysis section, the accompanying 
compensation tables and the related narrative disclosure in this proxy statement. 

This vote is non-binding. The Board and the Compensation Committee expect to consider the outcome of the vote when 
considering future executive compensation decisions to the extent they can determine the cause or causes of any significant 
negative voting results. At our 2023 annual meeting, shareholders owning 98 percent of the shares that were voted in this 
matter approved our executive compensation. 

As described at length in the Compensation Discussion and Analysis section of this proxy statement, we believe our executive 
compensation program is reasonable, competitive and strongly focused on pay for performance. The compensation of our 
Named Executive Officers varies depending upon the achievement of pre-established performance goals, both individual and 
corporate. Our short-term incentive is tied to earnings per share, safety performance targets, system safety and reliability 
targets, customer experience targets, and diversity targets that reward our executives when they deliver targeted results. Our 
long-term incentive performance shares or units vest based upon the level of achievement of certain pre-established 
performance goals over a three-year performance period as described in the Compensation Discussion and Analysis. Through 
stock ownership guidelines, equity incentives and clawback provisions, we align the interests of our executives with those of 
our shareholders and our long-term interests. Our executive compensation policies have enabled us to attract and retain 
talented and experienced senior executives who can drive financial and strategic growth objectives that are intended to 
enhance shareholder value. We believe that the 2023 compensation of our Named Executive Officers was appropriate and 
aligned with our 2023 results and positions us for long-term growth. 

Shareholders are encouraged to read the Compensation Discussion and Analysis, the accompanying compensation tables, 
and the related narrative disclosures to better understand the compensation of our Named Executive Officers. 

The advisory resolution to approve executive compensation is non-binding. However, our Board will consider shareholders to 
have approved our executive compensation if the number of votes cast “For” the proposal exceeds the number of votes cast 
“Against” the proposal. Abstentions and broker non-votes will have no effect on such vote. 

The Board recommends a vote FOR the advisory vote on executive compensation.

COMPENSATION DISCUSSION AND ANALYSIS 

INTRODUCTION 

This Compensation Discussion and Analysis describes our overall executive compensation policies and practices and 
specifically explains the compensation-related actions taken with respect to 2023 compensation for our Named Executive 
Officers included in the Summary Compensation Table. The Compensation Committee of the Board (the "Committee" for 
purposes of this Compensation Discussion and Analysis), is composed entirely of independent directors and is responsible for 
approving and overseeing our executive compensation philosophy, policies and programs. 

Our Named Executive Officers, based on 2023 positions and compensation levels, are:

KEY EXECUTIVE COMPENSATION OBJECTIVES  

Overall, our goal is to target total direct compensation (the sum of base salary, short-term incentive at target and long-term 
incentive at target) to be around the median of the appropriate market. Our executive compensation is designed to maintain an 
appropriate and competitive balance between fixed and variable compensation components including short-and long-term 
compensation, and cash and stock-based compensation. We believe that the performance basis for determining 
compensation should differ by each reward component – base salary, short-term incentive and long-term incentive. Incentive 
measures (short-term and long-term) should emphasize objective, quantitative operating measures. The performance 
measures for our incentive compensation plans are discussed below.

BEST PRACTICES IN EXECUTIVE COMPENSATION 

Our executive compensation program reflects the following best practices, which ensure effective compensation governance 
and align the interests of our shareholders and executives. 

What we do: 
A significant portion of executive pay is at risk by granting 
incentive awards that are based on continuing annual and 
long-term metrics tied to performance. 
Short-Term incentive plan awards are capped at 200% of 
target. 

Long-Term incentive plan awards are capped at 200% of 
target number of shares granted. 

Beginning with 2023 grants, non-vested equity awards are 
not accelerated after a change in control unless the 
executive is: (1) terminated without cause or good reason; or 
(2) the award is not assumed or substituted by the successor 
company  
Executives and directors are subject to stock ownership 
guidelines and retention requirements.

SETTING EXECUTIVE COMPENSATION 

X  No employment agreements with executives. 

What we do not do: 

Based upon our compensation philosophy, the Committee structures executive compensation to motivate our executives to 
achieve specified business goals and to reward them for achieving such goals. The key steps the Committee follows in setting 
executive compensation are to: 

Analyze executive compensation market data to ensure market competitiveness 

Review the components of executive compensation, including base salary, short-term incentive, long-term incentive, 

retirement, and other benefits 

Review total compensation and structure 

Review executive officer performance, responsibilities, experience, and other factors cited above to determine individual 

compensation levels 

EXECUTIVE COMPENSATION PROGRAM DESIGN OBJECTIVES 

Attract, retain, motivate, 
and encourage the 
development of highly 
qualified executives 

Provide competitive 
compensation 

Promote the 
relationship between 
pay and performance 

Promote corporate 
performance that is 
linked to our 
shareholders’ interests 

Recognize and reward 
individual performance 

Market Compensation Analysis 

The market for our executive talent is national in scope and is not focused on any one geographic location, area or region of 
the country. As such, our executive compensation should be competitive with the national market for executives. It should also 
reflect the executive’s responsibilities and duties and align with the compensation of executives at companies or business 
units of comparable size and complexity. The Committee gathers market information for our executives from the electric and 
gas utility industry and general industry. 

The Committee selects and retains the services of an independent consulting firm to periodically: 

7.5% Safety Index metrics

Review and evaluate our compensation program as compared to compensation practices of other companies with 

similar characteristics, including size, complexity, and type of business 

Review and assist with the establishment of a peer group of companies 

Provide a compensation analysis of the executive positions 

The Committee used the services of Meridian to evaluate 2023 compensation. Meridian gathered data from nationally 
recognized survey providers, as well as specific peer companies through public filings, which included: 

i.  Willis Towers Watson’s Compensation Data Bank (energy services and general industry); and 
ii.

The 20 peer companies ranged in annual revenue size from approximately $656 million to $8.1 billion, with the median at $2.4 
billion. The Company’s 2023 revenue was $2.3 billion. The survey data was adjusted for our relative revenue size using 
regression analysis. Our compensation peer companies included in the analysis for 2023 compensation decisions were: 

ALLETE Inc. 

Alliant Energy Corporation 

IDACORP Inc. 

MGE Energy Inc. 

ONE Gas, Inc. 

Pinnacle West Capital Corp. 

Ameren Corporation 

Atmos Energy Corp. 

Avista Corp.

NiSource, Inc. 

Portland General Electric Co.

South Jersey Industries, Inc. (1) 

NorthWestern Corp. 

OGE Energy Corp. 

Spire, Inc. 

(1) South Jersey Industries, Inc. is no longer an SEC registrant following completion of a merger in February 2023, and was therefore removed 
from the peer group. 

Meridian validated that the above Compensation Peer Group remains credible, includes size-appropriate peers, and reflects 
the Company's industry, complexity and market for executive talent.   

The salary surveys are one of several factors the Committee uses in setting appropriate compensation levels. Other factors 
include Company performance, individual performance and experience, the level and nature of the executive’s responsibilities, 
internal equity considerations and discussions with the CEO related to the other  senior executive officers' performance and 
contributions. 

Components of Executive Compensation 

The primary components of our executive compensation program consist of a base salary, a short-term incentive plan, and 
long-term incentives. In addition, we provide retirement and other benefits. The Committee reviews all components of each 
executive officer's compensation, including salary, short-term incentive, equity and other long-term incentive compensation 
values granted, and the current and potential value of the executive officer's total Black Hills Corporation equity holdings.  

The majority of the executives’ total compensation is granted as incentive compensation. Incentive compensation is intended 
to motivate and encourage our executives to drive performance and achieve superior results for our shareholders and align 
realized pay with stock performance. The Committee periodically reviews information provided by its compensation consultant 
to inform its determination of the appropriate level and mix of total compensation. The Committee believes that a significant 
portion of total target compensation should be comprised of variable compensation. In order to reward long-term growth while 
still encouraging focus on short-term results, the Committee establishes incentive targets that emphasize long-term 
compensation at a greater level than short-term compensation. 

Base Salary. Base salaries for all executives are reviewed annually. The base salary of our executives is also adjusted at the 
time of a promotion or material change in job responsibility, as appropriate. Evaluation of 2023 base salary adjustments 
occurred in January 2023. The base salary component of each position was compared to the median of the market data 
provided by the compensation consultant. The actual base salary of each officer was determined based on the executive’s 
performance, the experience level of the officer, the current position in a market-based salary range, and internal pay 
relationships.

 Ensure “buy-in” from participants with easily understood metrics 
 Meet the performance objectives of the plan to achieve over time an average payout equal to market competitive 

levels 

The short-term incentive, after applicable tax withholding, is distributed to the officer in the form of cash. Target award levels 
are established as a percentage of each participant’s base salary. A target award is typically set around the benchmark 50th 
percentile short-term incentive target award for comparable positions. The actual payout, if any, will vary, based on attainment 
of pre-established performance goals, between 0 and 200 percent of the individual executive’s short-term incentive target 
award level.

The threshold, target and maximum payout levels for our Named Executive Officers under the 2023 Short-Term Incentive Plan 
are shown in the Grants of Plan-Based Awards in 2023 table on page 38, under the heading “Estimated Future Payouts Under 
Non-Equity Incentive Plan Awards.” 

Early in the first quarter, the Committee evaluates actual performance in relation to the prior year’s targets and approves the 
actual payment of awards related to the prior plan year. The Committee reserves the discretion to adjust any award, and will 
review and take into account individual performance, level of contribution, and the accomplishment of specific project goals 
that were initiated throughout the plan year. The Committee also reserves discretion with respect to any payout related to 
safety goals if we experience an employee or contractor fatality during the plan period. For 2023, the Committee exercised its 
discretion and approved a $0.022 increase to EPS from ongoing operations, as adjusted, resulting in $3.932 of EPS for 
compensation purposes. The adjustment to EPS excluded certain project costs that were not anticipated when the original 
metrics were set. Except for the Committee's discretionary increase, earnings per share from ongoing operations, as adjusted, 
for incentive plan purposes were the same as earnings per share, diluted, reported externally to our investors. 

On January 25, 2024, the Committee approved a payout of 153.67% percent of target under the 2023 Short-Term Incentive 
Plan. The incentive plan payout was based on attainment of the following:

Actual awards made to each of our Named Executive Officers under the Short-Term Incentive Plan for 2023 are included in 
the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table on page 37. 

For the 2024 Short-Term Incentive Plan, we are maintaining our commitment to financial performance with EPS from ongoing 
operations as adjusted, changing our outcome-based safety metric to replace TCIR and PMVI with the Days Away, Restricted 
or Transferred Rate (DART), modifying our customer experience metrics to update our methodology for measuring customer 
satisfaction and customer effort to leverage internal customer feedback tools instead of NPS and JD Power and continuing our 
commitment to diversity by replacing diverse candidate slates and interview panels with a new metric intended to increase 
diversity in leadership positions. Our metrics for customer experience, diversity, and system safety and reliability demonstrate 
our continued efforts to improve our social and environmental ESG performance. 

Long-Term Incentive. Our Long-Term Incentive Plan (LTIP) is designed to focus executive performance on sustained long-
term results that drive or are based on shareholder value creation. Long-term incentive compensation is intended to: 

 Promote achievement of corporate goals by linking the interests of participants to those of our shareholders 
 Provide participants with an incentive for excellence in individual performance 
 Promote teamwork among participants 
 Motivate, retain, and attract the services of participants who make significant contributions to our success by allowing 

participants to share in such success 

 Meet the performance objectives of the plan to achieve an average payout equal to market competitive levels over 

time

Commission on February 14, 2024. 

The long-term incentive compensation component is composed of performance share units and restricted stock that vests 
ratably over three years. The Committee chose these components because linking executive compensation to stock price 
appreciation, total shareholder return, and other key financial and environmental metrics is an effective way to align the 
interests of management with those of our shareholders. The split between performance share units and restricted stock for 
each plan period is illustrated below:

The value of long-term incentives awarded is based primarily on competitive market-based data presented by the 
compensation consultant to the Committee, the impact each position has on our shareholder return, executive performance, 
and internal pay relationships. The actual amount realized may vary from the target award amounts. The Committee approved 
the target long-term incentive compensation level for each officer in January 2023. The 2023 long-term incentive was adjusted 
from 2022 levels for Mr. Evans to align more closely with market median and Ms. Nooney to align with her promotion to CFO.

Performance Share Units. Participants are awarded a target number of performance share units. The target number of 
performance share units is determined by dividing the Committee approved target performance value for the participant by the 
average closing price for the established number of trading days preceding the performance period.  

Vesting of performance share units associated with TSR is based on our total shareholder return over designated performance 
periods as measured against our Performance Peer Group. The Committee, with the guidance of its independent 
compensation consultant, periodically conducts a review of our Performance Peer Group to which our performance should be 
compared. Due to the extensive merger and acquisition activity in the industry and its contribution to relative performance 
volatility, the Committee chose to continue to use the companies in the EEI Index as the Performance Peer Group for 2023.  

A summary of the TSR performance criteria for the 2023-2025 performance share units is summarized in the table below: 

Percentile Ranking for 
Threshold Payout of 25% of 
Target Shares 

Percentile Ranking for 
Target Payout of 100% of

Maximum  Payout Level 

Possible Payout Range of 
Target 

Performance Share Plans 

25th percentile 

50th percentile 

90th percentile 

0-200% 

The 2023-2025 Performance plan, for the portion of the award that vests based on relative TSR, provides: (i) a threshold 
payout if relative TSR performance is below threshold but our TSR is at least 35 percent for the performance period; and (ii) 
the performance share plan payout is capped at 100 percent of target if TSR is negative. The additional provisions are 
intended to reduce the impact of one peer company’s performance on the relative TSR, and also increase accountability and 
expectations related to the Company’s performance.  

Vesting of performance share units associated with Earnings Per Share, Average Cost to Serve, and Emissions Reduction 
performance is determined based upon the Company's performance against established performance goals. The final value of 
the performance shares is based upon the number of shares of common stock that are ultimately earned, based upon our 
performance in relation to the performance criteria. 

Threshold performance results in a payout of 25 percent of the target share award. Target performance results in a payout of 
the target share award. Maximum performance results in a payout of 200 percent of the target share award. 

The performance share units and dividend equivalents, if earned, are paid in common stock. Performance share units are pro-
rated for the period of service in the events of retirement, death or disability. Performance share units vest in full under certain 
circumstances following a change in control. Performance awards are forfeited if an officer's employment is terminated for any 
reason other than those previously stated. 

Restricted Stock. Restricted stock awarded as long-term incentives vests one-third each year over a three-year period, and 
automatically vests in its entirety upon death, disability or under certain termination circumstances following a change in 
control. Dividends are paid on the restricted stock. Unvested restricted stock is forfeited if an officer’s employment is 
terminated for any reason other than those previously stated. 

Payouts under the Performance Share Plan have varied significantly over the last 10 years, as shown in the graph below. 
Each performance  period extends for three years. For the recently completed performance period, January 1, 2021 to 
December 31, 2023, the payout was based on attainment of the following:

The 2024-2026 Performance plan portion of our Long-Term Incentive plan retains our current four metrics. The Compensation 
Committee, with the guidance of its independent compensation consultant, adopted the Compensation Peer Group as the 
Company's Performance Peer Group beginning with the 2024-2026 Performance plan. This change was made to better align 
with our fuel mix as the companies in the EEI Index are electric-only utilities. 

Board and Management Roles in Compensation Decisions 

Role of Executive Officers in Compensation Decisions. In 2023, the Human Resources team, with the support of an 
external compensation consultant, reviewed all compensation programs to ensure that the programs do not encourage 
unnecessary risk-taking and instead encourage behaviors that support the values and operations of the Company. This review 
determined that the compensation programs of the Company do not encourage excessive risk-taking or have an adverse 
effect on the Company.   

The CEO annually reviews the performance of each of our senior executive officers. Based upon these performance reviews 
and market analysis conducted by compensation consultants, the CEO recommends the compensation for this group of 
officers to the Committee. 

Role of the Committee and Board in Setting Executive Compensantion. The Committee reviews and establishes the 
Company’s financial targets and the CEO’s goals and objectives for the year. After the end of each year, the Committee 
evaluates the CEO’s performance in light of established goals and objectives, with input from the other independent directors. 
Based upon the Committee’s evaluation and recommendation, the independent directors of the Board set the CEO’s annual 
compensation, including salary, short-term incentive, and long-term incentive compensation. 

The Committee reviews the CEO’s recommended compensation for our senior executive officers. The Committee may 
approve the CEO’s compensation recommendations for this group of officers or exercise its discretion by modifying any of the 
recommended compensation and award levels in its review and approval process. The Committee is required to approve all 
decisions regarding equity awards to our officers.

Summary 

In total, the Committee believes that the 2023 compensation actions, decisions and outcomes strongly reflect and reinforce our 
compensation philosophy and, in particular, emphasize the alignment between compensation and both performance and 
shareholder interests. At our 2023 annual meeting, shareholders owning 98 percent of the shares that were voted on this 
matter approved our executive compensation for 2022, which we consider highly supportive of our current compensation 
philosophy. In connection with establishing the 2023 executive compensation program, the Board reviewed the results of the 
say on pay vote, as well as market data and performance indicators. 

Governance Best Practices 

We have several governance programs in place to align our executive compensation with shareholder interests and to mitigate 
risks in our plans. These programs include stock ownership guidelines, mandatory and supplemental clawback policies, and 
the prohibition of hedging or pledging of Company stock. 

STOCK OWNERSHIP GUIDELINES 

The Committee has implemented stock ownership guidelines that apply to all officers based upon their level of responsibility. 
We believe it is important for our officers to hold a significant amount of our common stock to further align their interests with 
the interests of our shareholders. A “retention ratio” approach to stock ownership is incorporated into the guidelines. Officers 
are required to retain 100 percent of all shares owned, including shares awarded through our incentive plans (net of share 
withholding for taxes and, in the case of cashless stock option exercises, net of the exercise price and withholding for taxes) 
until specific ownership goals are achieved.  

The guidelines are shown below. 

Position 
CEO 
CFO 
Other Senior Officers 

Stock Ownership Value as 
Multiple of Base Salary 
6X 
3X 
3X 

At least annually, the Compensation Committee reviews common stock ownership to confirm the officers have met or are 
progressing toward their stock ownership guidelines. Generally, an officer may not sell common stock unless he or she owns 
common stock in excess of 110 percent of the applicable stock ownership guideline. With the exception of Mr. Keller and 
Messes. Jones and Nooney, who have all been in their current roles less than four years, all of our Named Executive Officers 
who are current officers have exceeded their stock ownership guidelines. 

CLAWBACK OF EXECUTIVE COMPENSATION 

We have adopted a Mandatory Compensation Recovery Policy that applies to all current and former Section 16 Officers. This 
policy is consistent with the final rules adopted by the SEC and the NYSE. In the event of an accounting restatement to correct 
an error that is (a) material to the previously issued financial statements or (b) would result in a material misstatement if the 
error were corrected in the current period, the Company will seek to recover erroneously awarded incentive compensation 
received by any current or former executive officer during the immediately preceding three years. This policy does not require 
a finding of fault to trigger a recoupment, rather recovery may be triggered absent fraud or willful misconduct by the executive. 
Erroneous compensation is the amount of compensation that is granted, earned or vested based upon attainment of a 
financial reporting measure included in an accounting restatement, as described above, that would not have been received 
had the financial statements in question been accurate. The Mandatory Compensation Recovery Policy is filed as an exhibit to 
the 2023 Form 10-K. 

The Company has also adopted a Supplemental Compensation Recovery Policy that also applies to our NEOs. Under this 
Policy, our Board may seek to recover incentive compensation received by the executive in the event that such executive 
officer willfully engaged in conduct which is reasonably likely to cause significant financial or reputational harm to the 
Company.   

UNLAWFUL INSIDER TRADING AND ANTI-HEDGING POLICY 

Black Hills Corporation has adopted policies and procedures designed to prohibit unlawful insider trading, hedging 
transactions and related practices. Specifically, Black Hills Corporation’s employees, officers and directors are prohibited from 
trading in the Company’s securities while in possession of material, nonpublic information, from pledging its securities as 
collateral, holding its securities in a margin account and entering into transactions that are designed to hedge or offset 
decreases in the market value of the securities. Additionally, certain employees and officers are subject to routine and non-

34

PROXYPROXY STATEMENT  | 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
  
 
 
routine blackout periods during which times trading in our securities is not permitted, as well as pre-clearance procedures to 
ensure compliance with applicable internal policies. 

Notwithstanding the prohibition against insider trading, the Policy aligns with the SEC rules that allow directors, officers and 
employees to trade in Black Hills Corporation Securities while aware of material, nonpublic information, so long as the trades 
occur pursuant to a binding contract, instruction or written trading program that complies with the requirements of Rule 10b5. 

2023 BENEFITS 

Retirement Benefits. We maintain a variety of employee benefit plans and programs in which our executive officers may 
participate. We believe it is important to provide post-employment benefits to our executive officers and the benefits we 
provide approximate retirement benefits paid by other employers to executives in similar positions. The Committee periodically 
reviews the benefits provided, with assistance from its compensation consultant, to maintain a market-based benefits package. 
Mr. Kinzley received a pension benefit payment in 2023. 

Several years ago, we adopted a defined contribution plan design as our primary retirement plan and amended our Defined 
Benefit Pension Plan (“Pension Plan”) for all eligible employees to incorporate a partial freeze in which the accrual of benefits 
ceased for certain participants while other participants were allowed an election to continue to accrue benefits. None of our 
Named Executive Officers met the age and service requirements to allow them to continue to accrue benefits under the 
Pension Plan. Employees who no longer accrue benefits under the Pension Plan now receive Company Retirement 
Contributions (“Retirement Contributions”) in the Retirement Savings Plan. The Retirement Contributions are an age and 
service points-based calculation. 

The 401(k) Retirement Savings Plan is offered to all our eligible employees and we provide matching contributions for certain 
eligible participants. All of our Named Executive Officers are participants in the 401(k) Retirement Savings Plan and received 
matching contributions in 2023. The matching contributions and the Retirement Contributions are included as “All Other 
Compensation” in the Summary Compensation Table on page 37. 

We also provide nonqualified plans to certain executives as approved by the Compensation Committee. The level of 
retirement benefits provided by the Pension Plan and Nonqualified Plans for each of our Named Executive Officers is reflected 
in the Pension Benefits for 2023 table on page 41. Our contributions to the Nonqualified Deferred Compensation Plan are 
included in the All Other Compensation column of the Summary Compensation Table on page 37 and the aggregate 
Nonqualified Deferred Compensation balance at December 31, 2023 is reported in the Nonqualified Deferred Compensation 
for 2023 table on page 43. These retirement benefits are explained in more detail in the accompanying narrative to the tables. 

Other Personal Benefits. We provide the personal use of a Company vehicle, executive health services, and limited 
reimbursement of financial planning services as benefits to our executive officers. The specific amount attributable to these 
benefits in 2023 is disclosed in the Summary Compensation Table on page 37. The Committee periodically reviews the other 
personal benefits provided to our executive officers and believes the current benefits are reasonable and consistent with our 
overall compensation program. 

CHANGE IN CONTROL BENEFIT 

Our Named Executive Officers may also receive severance benefits in the event of a qualifying termination in connection with 
a change in control. We have no employment agreements with our Named Executive Officers. However, change in control 
protections are common among our Compensation Peer Group and the Committee and our Board believes providing these 
agreements to our corporate and select subsidiary officers protects our shareholder interests in the event of a change in 
control by helping assure management focus and continuity.  

In 2022, our Compensation Committee approved revised form of incentive award agreements that require a "double trigger" 
before accelerated equity compensation will be paid to our Named Executive Officers. The double trigger provides benefits in 
association with: 

(1)  a change in control, and 

(2) 

(i)  a termination of employment other than by death, disability or by us for cause, or 

(ii)  a termination by the employee for good reason. 

35 

PROXY|  PROXY STATEMENT 
 
  
 
 
 
 
 
 
 
 
 
 
 
Our change in control agreements have expiration dates and our Board conducts a review of the change in control 
agreements at each renewal period. Our current change in control agreements expire November 15, 2025. In general, our 
change in control agreements provide a severance payment of up to 2.99 times average compensation for Mr. Evans, and up 
to two times average compensation for the other Named Executive Officers. The change in control agreements do not provide 
for excise tax gross-ups.  

See the Potential Payments upon Termination or Change in Control table on page 44 and the accompanying narrative for 
more information regarding our change in control agreements and estimated payments associated with a change in control. 

TAX AND ACCOUNTING IMPLICATIONS 

Section 162(m) of the U.S. Internal Revenue Code of 1986, as amended, places a limit of $1 million in compensation per year 
on the amount public companies may deduct with respect to certain executive officers. The Committee continues to believe 
that shareholder interests are best served if its discretion and flexibility in structuring and awarding compensation is not 
restricted, even though some past and/or future compensation awards result in non-deductible compensation expenses to the 
Company. The Committee's ability to continue to provide a competitive compensation package to attract, motivate and retain 
the Company's most senior executives is considered critical to the Company's success and to advancing the interests of its 
shareholders. 

REPORT OF THE COMPENSATION COMMITTEE 

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 
402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee 
recommended to our Board that the Compensation Discussion and Analysis be included in this proxy statement.

Stock Awards represent the grant date fair value related to restricted stock and performance share units that have been granted as a 
component of long-term incentive compensation. The grant date fair value is computed in accordance with the provisions of accounting 
standards for stock compensation. Assumptions used in the calculation of these amounts are included in Note 14 of the Notes to the 
Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2023. The amounts shown for 
the performance shares and performance share units represent the values that are based on the achievement of 100% of the target 
performance. Assuming achievement of the maximum 200% of target performance, the value of the performance share units would be: 
$4,018,777 for Mr. Evans, $893,040 for Ms. Nooney, $893,040 for Mr. Iverson, $372,162 for Ms. Jones, and $446,501 for Mr. Keller. 
Non-Equity Incentive Plan Compensation represents amounts earned under the Short-Term Incentive Plan. The Compensation 
Committee approved the payout of the 2023 awards on January 25, 2024 and the awards were paid on March 3, 2024. 
Change in Pension Value and Nonqualified Deferred Compensation Earnings represents the net positive increase in actuarial value of 
the Pension Plan and Pension Restoration Benefit (“PRB”) for the respective years. These benefits have been valued using the 
assumptions disclosed in Note 13 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the 
year ended December 31, 2023. Because these assumptions sometimes change between measurement dates, the change in value 
reflects not only the change in value due to additional benefits earned during the period and the passage of time but also reflects the 
change in value caused by changes in the underlying actuarial assumptions. 

The Pension Plan and PRB were frozen effective January 1, 2010 for participants who did not satisfy the age 45 and 10 years of 
service eligibility. Messrs. Evans, Kinzley and Iverson and Messes. Jones and Nooney did not meet the eligibility choice criteria and 
their benefits were frozen.  

Our Named Executive Officers receive employer contributions into a Nonqualified Deferred Compensation Plan (“NQDC”). The NQDC 
employer contributions are reported in the All Other Compensation column. No Named Executive Officer received preferential or above-
market earnings on nonqualified deferred compensation. The change in value attributed to each Named Executive Officer from each 
plan is shown in the table below:

No stock options were granted to our Named Executive Officers in 2023. 
The columns under “Estimated Future Payouts Under Non-Equity Incentive Plan Awards” show the range of payouts for 2023 
performance under our Short-Term Incentive Plan as described in the Compensation Discussion and Analysis under the section titled 
“Short-Term Incentive” on page 27. If the performance criteria are met, payouts can range from 50 percent of target at the threshold 
level to 200 percent of target at the maximum level. The non-equity incentive payment for 2023 performance, paid in 2024, has been 
made based on achieving the criteria described in the Compensation Discussion and Analysis, at 153.67 percent of target, and is 
shown in the Summary Compensation Table on page 37 in the column titled “Non-Equity Incentive Plan Compensation.” 
The columns under “Estimated Future Payouts Under Equity Incentive Plan Awards” show the range of payouts (in shares of stock) for 
the January 1, 2023 to December 31, 2025 performance period as described in the Compensation Discussion and Analysis under the 
section titled “Long-Term Incentive” on page 30. If the performance criteria are met, payouts can range from 25 percent of target to 200 
percent of target. If a participant retires, suffers a disability or dies during the performance period, the participant or the participant’s 
estate is entitled to that portion of the number of performance shares as such participant would have been entitled to had he or she 
remained employed through the end of the performance period, prorated for the number of months served. With the exception of 
certain terminations following a change in control, performance shares and performance share units are forfeited if employment is 
terminated for any other reason. During the performance period, dividends and other distributions paid with respect to the shares of 
common stock accrue for the benefit of the participant and are paid out at the end of the performance period. 
The column “All Other Stock Awards” reflects the number of shares of restricted stock granted on February 9, 2023 under our Amended 
and Restated 2015 Omnibus Incentive Plan. The restricted stock vests one-third each year over a three-year period, and automatically 
vests upon death or disability, with the exception of certain terminations following a change in control. Unvested restricted stock is 
forfeited if employment is terminated for any other reason. Dividends are paid on the restricted stock and the dividends that were paid 
in 2023 are included in the column titled “All Other Compensation” in the Summary Compensation Table on page 37.

The column “Grant Date Fair Value of Stock Awards” reflects the grant date fair value of each equity award computed in accordance 
with the provisions of accounting standards for stock compensation. The grant date fair value for the performance share units was 
$77.95 per share and was calculated on a weighted average basis considering the results of a Monte Carlo simulation model and the 
market value of our common stock as of the beginning of the performance period. Assumptions used in the calculation are included in 
Note 14 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 
2023. The grant date fair value for the restricted stock was $71.50 per share for the February 9, 2023 grant, which was the market 
value of our common stock on the date of grant as reported on the NYSE. 
In connection with his retirement, Mr. Kinzley did not receive any equity compensation awards for fiscal 2023; however, he did receive a 
cash payment in lieu of these awards in recognition of his partial year of service. See footnote (4) to our Summary Compensation table.

There were no stock options outstanding at December 31, 2023 for our Named Executive Officers. 
Vesting dates for restricted stock and performance share units are shown in the table below. The performance shares shown with a 
vesting date of January 25, 2024, are the actual equivalent shares, including dividend equivalents, earned for the performance period 
ended December 31, 2023. On January 25, 2024, the Compensation Committee confirmed that the performance criteria were met and 
there would be a payout of 16.21 percent of target. The performance shares with a vesting date of January 23, 2025 and the 
performance share units with a vesting date of January 23, 2026 are shown at a combination of threshold and target payout levels 
based upon performance as of December 31, 2023.

PENSION BENEFITS FOR 2023 

Several years ago, we adopted a defined contribution plan design as our primary retirement plan and amended our Pension 
Plan and Nonqualified Pension Plans for all eligible employees to incorporate a partial freeze in which the accrual of benefits 
ceased for certain participants while other participants were allowed an election to continue to accrue benefits. Employees 
eligible to elect continued participation were those employees who were at least 45 years old and had at least 10 years of 
eligible service with us as of January 1, 2010. None of our Named Executive Officers met the age and service requirement 
necessary to continue to accrue benefits under the Pension Plan. Rather, benefits under the Pension Plan were frozen for 
Messrs. Evans, Kinzley and Iverson and Messes. Jones and Nooney. Mr. Keller joined the Company after the plans were 
frozen and therefore does not participate in the plans. Mr. Kinzley received a pension benefit payment during the fiscal year 
ended December 31, 2023. 

The present value accumulated by each Named Executive Officer from each plan is shown in the table below:

The number of years of credited service represents the number of years used in determining the benefit for each plan. 
The present value of accumulated benefits was calculated assuming the participants will work until retirement, benefits commence at 
age 62 and using the discount rate, mortality rate and assumed payment form assumptions consistent with those disclosed in Note 13 
of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2023.

DEFINED BENEFIT PENSION PLAN 

Our Pension Plan is a qualified pension plan. As discussed above, several years ago we amended our Pension Plan to 
incorporate a partial freeze in which the accrual of benefits ceased for certain participants while other participants were 
allowed an election to continue to accrue benefits.  

The Pension Plan provides benefits at retirement based on length of employment service and average compensation levels 
during the highest five consecutive years of the last ten years of service. For purposes of the benefit calculation, earnings 
include wages and other cash compensation received from us, including any bonus, commission, unused paid time off or 
incentive compensation. It also includes any elective before-tax contributions made by the employee to a Company-sponsored 
cafeteria plan or 401(k) plan. However, it does not include any expense reimbursements, taxable fringe benefits, moving 
expenses or moving/relocation allowances, nonqualified deferred compensation, non-cash incentives, stock options and any 
payments of long-term incentive compensation such as restricted stock or payments under performance share plans. The 
Internal Revenue Code places maximum limitations on the amount of compensation that may be recognized when determining 
benefits of qualified pension plans. In 2023, the maximum amount of compensation that could be recognized when 
determining compensation was $330,000 (called “covered compensation”). Our employees do not contribute to the plan. The 
amount of the annual contribution by us to the plan is based on an actuarial determination. 

The benefit formula for the Named Executive Officers in the plan is the sum of (a) and (b) below: 

(a)  Credited Service after January 31, 2000 

0.9% of average earnings (up to covered 
compensation), multiplied by credited service 
after January 31, 2000 minus the number of 
years of credited service before January 31, 
2000 

Plus 

1.3% of average earnings in excess of covered 
compensation, multiplied by credited service after 
January 31, 2000 minus the number of years of 
credited service before January 31, 2000 

Plus 

(b)  Credited Service before January 31, 2000 

1.2% of average earnings (up to covered 
compensation), multiplied by credited service 
before January 31, 2000 

Plus 

1.6% of average earnings in excess of covered 
compensation, multiplied by credited service 
before January 31, 2000 

Pension benefits are not reduced for social security benefits. The Internal Revenue Code places maximum limitations on 
annual benefit amounts that can be paid under qualified pension plans. In 2023, the maximum benefit payable under qualified 
pension plans was $265,000. Accrued benefits become 100 percent vested after an employee completes five years of service.  

Normal retirement is defined as age 65 under the plan. However, a participant may retire and begin taking unreduced benefits 
at age 62 with five years of service. Participants who have completed at least five years of credited service can retire and 
receive defined benefit pension benefits as early as age 55. However, the retirement benefit will be reduced by five percent for 
each year of retirement before age 62. All our Named Executive Officers who are eligible for pension benefits, with the 
exception of Messes. Jones and Nooney, are currently age 55 or older and are entitled to early retirement benefits under this 
provision. 

PENSION RESTORATION BENEFIT 

We also have a Pension Restoration Benefit. This is a nonqualified supplemental plan, in which benefits are not tax deductible 
until paid. The plan is designed to provide the higher paid executive employee a retirement benefit which, when added to 
social security benefits and the pension to be received under the Pension Plan, will approximate retirement benefits being paid 
by other employers to their employees in similar executive positions. The employee’s pension from the qualified Pension Plan 
is limited by the Internal Revenue Code. The 2023 pension limit was set at $265,000 annually and the compensation taken 
into account in determining contributions and benefits could not exceed $330,000 and could not include nonqualified deferred 
compensation. The amount of deferred compensation paid under nonqualified plans is not subject to these limits. 

As a result of the change in the Pension Plan discussed above, the benefits for certain officers (including Messrs. Evans and 
Kinzley) under the Nonqualified Pension Plans were significantly reduced because the nonqualified benefit calculations were 
linked to the benefits earned in the Pension Plan. The Compensation Committee amended the Nonqualified Deferred 
Compensation Plan to provide non-elective nonqualified restoration benefits to those affected officers who were not eligible to 
continue accruing benefits under the Pension Plan and Nonqualified Pension Plans.

Pension Restoration Benefit. In the event that at the time of a participant’s retirement, the participant’s salary level exceeds 
the qualified Pension Plan annual compensation limitation ($330,000 in 2023) or includes nonqualified deferred compensation, 
then the participant will receive an additional benefit, called a “Pension Restoration Benefit,” which is measured by the 
difference between (i) the monthly benefit that would have been provided to the participant under the Pension Plan as if there 
were no annual compensation limitation and no exclusion on nonqualified deferred compensation, and (ii) the monthly benefit 
to be provided to the participant under the Pension Plan. The Pension Restoration Benefit applies to Messrs. Evans and 
Kinzley. 

NONQUALIFIED DEFERRED COMPENSATION FOR 2023 

We have a Nonqualified Deferred Compensation Plan for a select group of management or highly compensated employees. 
Eligibility to participate in the plan is determined by the Compensation Committee and includes our Named Executive Officers. 

A summary of the activity in the plan and the aggregate balance as of December 31, 2023 for our Named Executive Officers is 
shown in the following table. Our Named Executive Officers received no withdrawals or distributions from the plan in 2023.

Because amounts included in this column do not include above-market or preferential earnings, none of these amounts are included in 
the “Change in Pension Value and Nonqualified Deferred Compensation Earnings” column of the Summary Compensation Table.  
(3)  Messrs. Evans’, Iverson’s, Keller's, Kinzley's and Messes. Nooney's and Jones' aggregate balances at December 31, 2023 include 
$1,526,704, $291,104, $132,308, $516,084, $76,231 and $63,682, respectively, which are included in the Summary Compensation 
Table as 2023, 2022 and 2021 compensation. 
In April of 2022, the Compensation Committee eliminated the supplemental target contribution for all future participants in the plan.  All 
our Named Executive Officers were participants prior to this elimination and maintain entitlement to supplemental target contributions. 

(4) 

Eligible employees may elect to defer up to 50 percent of their base salary and up to 100 percent of their Short-Term Incentive 
Plan award. In addition, the Nonqualified Deferred Compensation Plan was amended to provide certain officers whose 
Pension Plan benefit and Nonqualified Pension Plan benefits were frozen with non-elective supplemental matching 
contributions equal to 6 percent of eligible compensation in excess of the Internal Revenue Code limit plus matching 
contributions, if any, lost under the 401(k) Retirement Savings Plan due to nondiscrimination test results and provides non-
elective supplemental age and service points-based contributions that cannot be made to the 401(k) Retirement Savings Plan 
due to the Internal Revenue Code limit (“Supplemental Matching and Retirement Contributions”). It also provides supplemental 
target contributions equal to a percentage of compensation that may differ by executive, based on the executive’s current age 
and length of service with us, as determined by the plans’ actuary (“Supplemental Target Contributions”). Messrs. Evans, 
Kinzley, Iverson, and Keller and Messes. Jones and Nooney received Supplemental Target Contributions of 20 percent, 17.5 
percent, 8 percent, 8 percent, 8 percent, and 8 percent respectively. 

The deferrals are deposited into hypothetical investment accounts where the participants may direct the investment of the 
deferrals as allowed by the plan. The investment options are the same as those offered to all employees in the 401(k) 
Retirement Savings Plan except for a fixed rate option, which was set at 5.10 percent in 2023. Investment earnings are

the participant's distribution election. The participants may elect either a lump sum payment or annual or monthly installments 
over a period of years designated by the participant, but not to exceed 10 years. As of January 1, 2024, Messrs. Evans and 
Iverson and Messes. Jones and Nooney are 100 percent vested in the plan. 

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL 

The following table describes the potential payments and benefits under our compensation and benefit plans and 
arrangements to which our Named Executive Officers would be entitled upon termination of employment. Except for (i) certain 
terminations following a change in control (“CIC”), as described below, (ii) pro-rata payout of incentive compensation and the 
acceleration of vesting of equity awards upon retirement, death or disability, and (iii) certain pension and nonqualified deferred 
compensation arrangements described under Pension Benefits for 2023 and Nonqualified Deferred Compensation for 2023 
above, there are no agreements, arrangements or plans that entitle the Named Executive Officers to severance, perquisites, 
or other enhanced benefits upon termination of their employment. Any agreements to provide other payments or benefits to a 
terminating executive officer would be in the discretion of the Compensation Committee. 

The amounts shown below assume that such termination was effective as of December 31, 2023, and thus includes estimates 
of the amounts that would be paid out to our Named Executive Officers upon their termination. The table does not include 
amounts such as base salary, short-term incentives and stock awards that the Named Executive Officers earned due to 
employment through December 31, 2023 and distributions of vested benefits such as those described under Pension Benefits 
for 2023 and Nonqualified Deferred Compensation for 2023. The table also does not include a value for outplacement services 
because this would be a de minimis amount. The actual amounts to be paid can only be determined at the time of such 
Named Executive Officer’s separation from us.

The amounts reflected for after a change in control (with no involuntary or good reason termination) contemplate the assumption or 
replacement of the equity awards by the successor entity. 
The amounts reflected for involuntary or good reason termination after a change in control include the benefits a Named Executive 
Officer would receive in the event of a change followed by an involuntary or good reason termination. 
Assumes that in the event of a change in control, Mr. Evans will receive an additional three years of credited and vesting service and 
the other Named Executive Officers will receive an additional two years of credited and vesting service towards the benefit accrual 
under their applicable retirement plans. For Messrs. Evans, Kinzley, and Iverson and Messes. Jones and Nooney this would be the 
Retirement Contributions and Nonqualified Deferred Compensation contributions. The benefits will immediately vest and payments will 
commence at the earliest eligible date unless the executive has elected a later date for the nonqualified plans. With the exception of 
Messes. Jones and Nooney, our Named Executive Officers are age 55 or older and are already retirement eligible.

(4)  Welfare benefits include medical coverage, dental coverage, life insurance, short-term disability coverage and long-term disability 
coverage. The calculation assumes that the Named Executive Officer does not take employment with another employer following 
termination, elects continued welfare benefits until age 55 or, if later, the end of the two year benefit continuation period (three years for 
Mr. Evans) and elects retiree medical benefits thereafter. Retirement is assumed to occur at the earliest eligible date. 
In the event of death or disability, the acceleration of equity awards represents the acceleration of unvested restricted stock and the 
assumed payout of the pro-rata share of the performance shares for the January 1, 2022 to December 31, 2024 and January 1, 2023 to 
December 31, 2025 performance periods. In the event of retirement, all unvested restricted stock is forfeited and the acceleration of 
equity awards represents only the pro-rata share of the performance shares and performance share units. We assumed a 20.0 percent 
payout of the performance shares for the January 1, 2022 to December 31, 2024 performance period and a 13.3 percent payout of 
target for the January 1, 2023 to December 31, 2025 performance period based on assumed target achievement of performance 
metrics for EPS and average cost to serve and, for relative total shareholder return, our Monte Carlo valuations at December 31, 2023.  

In the event of a change in control without an involuntary or good reason termination after a change in control, the acceleration of equity 
awards only occurs if the awards are not assumed or replaced by the successor entity. 

In the event of a change in control or an involuntary or good reason termination after a change in control, the acceleration of equity 
awards represents the acceleration of unvested restricted stock and performance share units calculated as if the performance period 
ended on December 31, 2023 for the January 1, 2022 to December 31, 2024, and January 1, 2023 to December 31, 2025 performance 
periods. 

(6) 

The valuation of the restricted stock and performance share units was based upon the closing price of our common stock on December 
31, 2023. 
The amounts for Mr. Kinzley reflect benefits he received in connection with his retirement effective July 3, 2023. As a result, no other 
scenarios are presented for Mr. Kinzley. As disclosed in footnote (6) to our Summary Compensation Table, Mr. Kinzley also received a 
cash payment in lieu of any equity compensation awards for fiscal 2023. 

Payments Made Upon Termination. Regardless of the manner in which a Named Executive Officer’s employment 
terminates, the Named Executive Officer or his/her beneficiaries may be entitled to receive amounts earned during his/her 
term of employment. These include: 
 
 
 
 

accrued salary and unused vacation pay; 
amounts vested under the Pension Plan and Nonqualified Pension Plans; 
amounts vested under the Nonqualified Deferred Compensation Plan; and 
amounts vested under the 401(k) Retirement Savings Plan. 

Payments Made Upon Retirement. In the event of retirement of a Named Executive Officer, in addition to the items identified 
above, he/she will also receive the benefit of the following: 
 

a pro-rata share of the performance shares for each outstanding performance period upon completion of the 
performance period; and 
a pro-rata share of the actual payout under the Short-Term Incentive Plan upon completion of the incentive period. 

 

Payments Made Upon Death or Disability. In the event of death or disability of a Named Executive Officer, in addition to the 
items identified above for payments made upon termination, he/she will also receive the benefit of the following: 
 
 

accelerated vesting of restricted stock and restricted stock units; 
a pro-rata share of the performance shares for each outstanding performance period upon completion of the 
performance period; and 
a pro-rata share of the actual payout under the Short-Term Incentive Plan upon completion of the incentive period. 

 

Payments Made Upon a Change in Control. Our Named Executive Officers have change in control agreements that 
terminate November 15, 2025. The renewal of the change in control agreements is at the discretion of the Compensation 
Committee and the Board. The change in control agreements provide for certain payments and other benefits to be payable 
upon a change in control and a subsequent termination of employment, either involuntary or for a good reason. In order to 
receive any payments under the agreements, the Named Executive Officer must sign a waiver and release of claims that 
includes a one-year non-competition clause and two-year non-solicitation and non-disparagement clauses. 

A change in control is defined in the agreements as: 
 

an acquisition of 30 percent or more of our common stock, except for certain defined acquisitions, such as acquisition by 
employee benefit plans, us, any of our subsidiaries, or acquisition by an underwriter holding the securities in connection 
with a public offering thereof; or 
members of our incumbent Board cease to constitute at least a majority of the members of the Board, with the 
incumbent Board being defined as those individuals consisting of the Board on October 1, 2022 and any other directors 
elected subsequently whose election was approved by the incumbent Board; or 
approval by our shareholders of: 
-  a merger, consolidation, or reorganization; 
- 
-  an agreement for sale or other disposition of all or substantially all of our assets, with exceptions for 

liquidation or dissolution; or 

transactions which do not involve an effective change in control of voting securities or Board membership, and 
transfers to subsidiaries or sale of subsidiaries; and 

 

 

45 

PROXY|  PROXY STATEMENT 
 
 
 
 
 
 
 
 
 
 

all regulatory approvals required to effect a change in control have been obtained and the transaction constituting the 
change in control has been consummated. 

In the change in control agreements, a good reason for termination that triggers payment of benefits includes: 
 
 
 
 
 

a material reduction of the executive’s authority, duties or responsibilities; 
a material reduction in the executive’s base salary or annual incentive target opportunity; 
any material breach by us of any provisions of the change in control agreement; 
requiring the executive to be based outside a 50-mile radius from his or her usual and normal place of work; or 
our failure to obtain an agreement, satisfactory to the executive, from any successor company to assume and agree to 
perform under the change in control agreement. 

Upon a change in control, an employment contract with Mr. Evans will become effective for a three-year period and for a two-
year period for the other Named Executive Officers. During this time, the executive will receive annual compensation at least 
equal to the highest rate in effect at any time during the one-year period preceding the change in control and will also receive 
employment welfare benefits, pension benefits and supplemental retirement benefits on a basis no less favorable than those 
received prior to the change in control. Annual compensation is defined to include amounts which are includable in the gross 
income of the executive for federal income tax purposes, including base salary, targeted short-term incentive, targeted long-
term incentive grants and awards, and matching contributions or other benefits payable under the 401(k) Retirement Savings 
Plan, but exclude restricted stock awards, performance units or stock options that become vested or exercisable pursuant to a 
change in control. 

If a Named Executive Officer’s employment is terminated prior to the end of the covered time by us for cause or disability, by 
reason of the Named Executive Officer’s death, or by the Named Executive Officer without good reason, the Named Executive 
Officer will receive all amounts of compensation earned or accrued through the termination date. If the Named Executive 
Officer’s employment is terminated because of death or disability, the Named Executive Officer or their beneficiaries will also 
receive a pro rata bonus equal to 100 percent of the target incentive for the portion of the year served. 

If Mr. Evans’ employment is terminated during the employment term (other than by reason of death) (i) by us other than for 
cause or disability, or (ii) by Mr. Evans for a good reason, then Mr. Evans is entitled to the following benefits: 
 

all accrued compensation, a pro-rata short-term incentive bonus and accelerated vesting of restricted stock and 
performance units valued at target as of the date of the change in control; 
severance pay equal to 2.99 times Mr. Evans’ severance compensation defined as his base salary and short-term 
incentive target on the date of the change in control;  
continuation of employee welfare benefits for eighteen months following the termination date unless Mr. Evans becomes 
covered under the health insurance coverage of a subsequent employer which does not contain any exclusion or 
limitation with respect to any preexisting condition of Mr. Evans or his eligible dependents; 
following the three-year period, Mr. Evans may elect to receive coverage under the employee welfare plans of the 
successor entity at his then-current level of benefits (or reduced coverage at his election) by paying the premiums 
charged to regular full-time employees for such coverage, and is eligible to continue receiving such coverage through 
the date of his retirement; 
three additional years of service and age will be credited to Mr. Evans’ retiree medical savings account and the account 
balance will become fully vested and he is eligible to use the account balance to offset retiree medical premiums at the 
later of age 55 or the end of the three year continuation period; 
three years of additional credited service under the Pension Restoration Plan and Pension Plan; and 
outplacement assistance services for up to six months.

If any other NEO’s employment is terminated during the employment term (other than by death) (i) by us other than for cause 
or disability, or (ii) by the NEO for a good reason, then the NEO is entitled to the following benefits: 
 

all accrued compensation, a pro-rata short-term incentive bonus and accelerated vesting of restricted stock and 
performance units valued at target as of the date of the change in control; 
severance pay equal to two times the NEO’s severance compensation defined as the NEO’s base salary and short-term 
incentive target on the date of the change in control;  
continuation of employee welfare benefits for eighteen months following the termination date unless the NEO becomes 
covered under the health insurance coverage of a subsequent employer which does not contain any exclusion or 
limitation with respect to any preexisting condition of the NEO or the NEO’s eligible dependents; 
following the two-year period, the NEO may elect to receive coverage under the employee welfare plans of the 
successor entity at their then-current level of benefits (or reduced coverage at the NEO’s election) by paying the 
premiums charged to regular full-time employees for such coverage, and is eligible to continue receiving such coverage 
through the date of their retirement; 
two additional years of service and age will be credited to the NEO’s retiree medical savings account and the account 
balance will become fully vested and the NEO is eligible to use the account balance to offset retiree medical premiums 
at the later of age 55 or the end of the two year continuation period; 
two years of additional credited service under the executives’ applicable retirement plans; and 
outplacement assistance services for up to six months.

The Peer Group TSR set forth in this table utilizes the Edison Electric Institute Index (“EEI Index”), which we also utilize in the stock 
performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2023. 
The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the 
Company and in the EEI Index, respectively. All dollar values assume reinvestment of the pre-tax value of dividends paid by 
companies, where applicable, included in the EEI Index. Historical stock performance is not necessarily indicative of future stock 
performance. 

(5)  We determined EPS from ongoing operations, as adjusted (non-GAAP) to be the most important financial performance measure used 
to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2023. More information on EPS from 
ongoing operations, as adjusted can be found in the Short-Term Incentive section of Compensation Discussion and Analysis. This 
performance measure may not have been the most important financial performance measure for years 2022, 2021, and 2020 and we 
may determine a different financial performance measure to be the most important financial performance measure in future years. 

Relationship between Pay and Performance 

The charts shown below present a graphical comparison of compensation actually paid to the PEO and the average 
compensation actually paid to the other NEOs set forth in the Pay Versus Performance table above, as compared against the 
following Company performance measures: (1) Total shareholder return (TSR); (2) Peer group TSR; (3) Net income; and (4) 
EPS from ongoing operations, as adjusted. As presented, the first chart below compares the Company's TSR and peer group 
TSR, assumes an initial investment of $100 on December 31, 2019, assumes all dividends were reinvested and depicts 
performance at the end of each applicable year.

Electric to cost-effectively achieve the State of Colorado’s requirement calling upon electric 
utilities to reduce GHG emissions by a minimum of 80% from 2005 levels by 2030. Based 
on initial modeling, the preferred resource portfolio proposes the addition of approximately 
400 MW of clean energy resources (100 MW of wind, 200-250 MW of solar and 50 MW of 
battery storage) to Colorado Electric's system. The final mix of resources will be 
determined by the results of a competitive solicitation that was issued in July 2023.

South Dakota Electric owns 35% of a AC-DC-AC transmission tie that interconnects the 
Western and Eastern transmission grids, which are independently-operated transmission 
grids serving the western and eastern United States, respectively. Basin Electric Power 
Cooperative owns the remaining ownership percentage. This transmission tie allows us to 
buy and sell energy in the Eastern grid without having to isolate and physically reconnect 
load or generation between the two transmission grids, thus enhancing the reliability of our 
system. It accommodates scheduling transactions in both directions simultaneously, 
provides additional opportunities to sell excess generation or to make economic purchases 
to serve our native load and contract obligations, and enables us to take advantage of 
power price differentials between the two grids. The total transfer capacity of the tie is 400 
MW, including 200 MW from West to East and 200 MW from East to West.

Purchased Power. We have executed various PPAs to support our Electric Utilities’ capacity and energy needs beyond our 
regulated power plants’ generation, which include long-term related party agreements with our non-regulated power generation 
businesses. See additional information in Note 3 of the Notes to Consolidated Financial Statements in this Annual Report on 
Form 10-K.

Coal Mining. We own and operate a single coal mine through our WRDC subsidiary which is reported within our Electric Utilities 
segment. We surface mine, process and sell low-sulfur sub-bituminous coal at our mine located immediately adjacent to our 
Gillette Energy Complex in the Powder River Basin in northeastern Wyoming, where our five coal-fired power plants are located. 
We produced approximately 3.7 million tons of coal in 2023.

The mine provides low-sulfur coal directly to these five power plants via a conveyor belt system, minimizing transportation costs. 
The fuel can be delivered to our adjacent power plants at very cost competitive prices (i.e., $1.14 per MMBtu for year ended 
December 31, 2023) when compared to alternatives. Nearly all of the mine’s production is sold to our on-site generation facilities 
under long-term supply contracts.

As of December 31, 2023, we estimated our recoverable reserves to be approximately 179 million tons, based on a life-of-mine 
engineering study utilizing currently available drilling data and geological information prepared by internal engineering analyses. 
The recoverable reserve life is equal to approximately 48 years at the current production levels.

Transmission and Distribution. Through our Electric Utilities, we own electric transmission and distribution systems composed 
of high voltage lines (greater than 69 kV) and low voltage lines (69 kV or less). We also jointly operate an electric transmission 
system, referred to as the Common Use System, with Basin Electric Power Cooperative and Powder River Energy Corporation. 
Each participant in the Common Use System individually owns assets that are operated together for a single system. The 
Common Use System also provides transmission service to our Transmission Tie. South Dakota Electric owns 35% of the 
Transmission Tie. The Transmission Tie is further discussed in Note 6 of the Notes to Consolidated Financial Statements in this 
Annual Report on Form 10-K.

Seasonal Variations of Business. Our Electric Utilities are seasonal businesses and weather patterns may impact their 
operating results. Demand for electricity is sensitive to seasonal cooling, heating and industrial load requirements, as well as 
market price. In particular, cooling demand is often greater in the summer and heating demand is often greater in the winter.

operating results. Demand for electricity is sensitive to seasonal cooling, heating and industrial load requirements, as well as 

market price. In particular, cooling demand is often greater in the summer and heating demand is often greater in the winter.

Competition. We generally have limited competition for the retail generation and distribution of electricity in our service areas.  
Various legislative or regulatory restructuring and competitive initiatives have been discussed in several of the states in which 
our utilities operate. These initiatives would be aimed at increasing competition or providing for distributed generation. To date, 
these initiatives have not had a material impact on our utilities. In Colorado, our electric utility is subject to rules which may 
require competitive bidding for generation supply. Because of these rules, we face competition from other utilities and non-
affiliated IPPs for the right to supply electric energy and capacity for Colorado Electric when resource plans require additional 
resources. Additionally, electrification initiatives in our service territories could increase demand for electricity and increase 
customer growth.

The independent power industry consists of many strong and capable competitors, some of which may have more extensive 
operations or greater financial resources than we possess. With respect to the merchant power sector, FERC has taken steps to 
increase access to the national transmission grid by utility and non-utility purchasers and sellers of electricity to foster 
competition within the wholesale electricity markets. Our non-regulated power generation businesses could face greater 
competition if utilities are permitted to robustly invest in power generation assets. Conversely, state regulations requiring utilities 
to competitively bid generation resources may provide opportunity for IPPs in some regions. To date, these initiatives have not 
had a material impact on our non-regulated power generation businesses.

Our mining business strategy is to sell nearly all of our production to on-site generation facilities under long-term supply 
contracts. Historically, any off-site sales have been to consumers within close proximity to WRDC. Coal competes with other 
energy sources, such as natural gas, nuclear, wind, solar and hydropower. Costs and other factors relating to these alternative 
fuels, such as safety, environmental and availability considerations affect the overall demand for coal as a fuel.

Gas Utilities

We conduct natural gas utility operations through our Arkansas, Colorado, Iowa, Kansas, Nebraska and Wyoming subsidiaries. 
Our Gas Utilities transport and distribute natural gas through our distribution network to our retail customers. Additionally, we sell 
contractual pipeline capacity and gas commodities to other utilities and marketing companies, including our affiliates, on an as-
available basis.

We also provide non-regulated services to our regulated customers. Black Hills Energy Services provides natural gas supply to 
approximately 53,000 retail distribution customers under the Choice Gas Program in Nebraska and Wyoming. Additionally, we 
provide services under the Service Guard Comfort Plan, Tech Services and HomeServe.

We procure natural gas for our distribution customers from a diverse mix of producers, processors and marketers and generally 
use hedging, physical fixed-price purchases and market-based price purchases to achieve dollar-cost averaging within our 
natural gas portfolio. The majority of our procured natural gas is transported in interstate pipelines under firm transportation 
service agreements.

In addition to company-owned regulated underground natural gas storage assets in Arkansas, Colorado and Wyoming, we also 
contract with third-party transportation providers for natural gas storage service to provide gas supply during the winter heating 
season and to meet peak day customer demand for natural gas.

Seasonal Variations of Business. Our Gas Utilities are seasonal businesses and weather patterns may impact their operating 
results.  Demand for natural gas is sensitive to seasonal heating and industrial load requirements, as well as market price.  In 
particular, demand is often greater in the winter months for heating. Natural gas is used primarily for residential and commercial 
heating, and demand for this product can depend heavily upon weather throughout our service territories. As a result, a 
significant amount of natural gas revenue is normally recognized in the heating season consisting of the first and fourth quarters. 
Demand for natural gas can also be impacted by summer temperatures and precipitation, which can affect demand for irrigation.

Competition. We generally have limited competition for the retail distribution of natural gas in our service areas. Various 
restructuring and competitive initiatives have been discussed in several of the states in which our utilities operate. These 
initiatives are aimed at increasing competition. Additionally, electrification initiatives in our service territories could negatively 
impact demand for natural gas and decrease future growth. To date, these initiatives have not had a material impact on our 
utilities. Although we face competition from independent marketers for the sale of natural gas to our industrial and commercial 
customers, in instances where independent marketers displace us as the seller of natural gas, we still collect fees for 
transporting the gas through our distribution network.

Rates and Regulation

Our Utilities are subject to the jurisdiction of the public utility commissions in the states where they operate and the FERC for 
certain assets and transactions. These commissions oversee services and facilities, rates and charges, accounting, valuation of 
property, depreciation rates and various other matters. Rate decisions are influenced by many factors, including the cost of 
providing service, capital expenditures, the prudence of costs we incur, views concerning appropriate rates of return, general 
economic conditions and the political environment. Certain commissions also have jurisdiction over the issuance of debt or 
securities and the creation of liens on property located in their states to secure bonds or other securities.

The regulatory provisions for recovering the costs of service vary by jurisdiction. Our Utilities have cost recovery mechanisms 
that allow us to pass the prudently-incurred cost of natural gas, fuel and purchased power to customers. These mechanisms 
allow the utility operating in that state to collect or refund the difference between the cost of commodities and certain services 
embedded in our base rates and the actual cost of the commodities and certain services without filing a general rate review. In 
addition, some jurisdictions allow us to recover certain costs or earn a return on capital investments placed in service between 
base rate reviews through approved rider tariffs, such as energy efficiency plan costs and system safety and integrity 
investments. These tariffs allow the utility a return on the investment.

FERC

The Federal Power Act gives FERC exclusive rate-making jurisdiction over wholesale sales of electricity and the transmission of 
electricity in interstate commerce. Pursuant to the Federal Power Act, all public utilities subject to FERC’s jurisdiction must 
maintain tariffs and rate schedules on file with FERC that govern the rates, and terms and conditions for the provision of FERC-
jurisdictional wholesale power and transmission services. Public utilities are also subject to accounting, record-keeping and 
reporting requirements administered by FERC. FERC also places certain limitations on transactions between public utilities and 
their affiliates. Our electric utility subsidiaries provide FERC-jurisdictional services subject to FERC’s oversight.

Our Electric Utilities entities are authorized by FERC to make wholesale sales of electric capacity and energy at market-based 
rates under tariffs on file with FERC. As a condition of their market-based rate authority, Electric Quarterly Reports are filed with 
FERC. Our Electric Utilities own and operate FERC-jurisdictional interstate transmission facilities and provide open access 
transmission service under tariffs on file with FERC. Our Electric Utilities are subject to routine audit by FERC with respect to 
their compliance with FERC’s regulations.

PUHCA 2005 provides FERC authority with respect to the books and records of a utility holding company. As a utility holding 
company whose assets consist primarily of investments in our subsidiaries, including subsidiaries that are public utilities and also 
a centralized service company subsidiary, BHSC, we are subject to FERC’s authority under PUHCA 2005.

PUHCA 2005 reiterated the definition and benefits of EWG status. Under PUHCA 2005, an EWG is an entity or generator 
engaged, directly or indirectly through one or more affiliates, exclusively in the business of owning, operating or both owning and 
operating all or part of one or more eligible facilities and selling electric energy at wholesale. Though EWGs are public utilities 
within the definition set forth in the Federal Power Act and are subject to FERC regulation of rates and charges, they are exempt 
from other FERC requirements. Through its subsidiaries, Black Hills Corporation is affiliated with two EWGs, Wygen I and 
Pueblo Airport Generation (facilities #4-5). Both of these EWGs have been granted market-based rate authority.

NERC

The Energy Policy Act of 2005 included provisions to create an Electric Reliability Organization, which is required to promulgate 
mandatory reliability standards governing the operation of the bulk power system in the U.S. FERC certified NERC as the 
Electric Reliability Organization and also issued an initial order approving many reliability standards that went into effect in 2007. 
Entities that violate standards can be subject to fines and can also be assessed non-monetary penalties, depending upon the 
nature and severity of the violation.

Pipeline Security

In May and July 2021, the TSA issued security directives in response to a ransomware attack on the Colonial Pipeline that 
occurred earlier in 2021 that included several new cybersecurity requirements for critical pipeline owners and operators. Among 
these requirements is the implementation of specific mitigation measures to protect against ransomware attacks and other 
known threats to information and operational technology systems; development and implementation of a cybersecurity 
contingency and recovery plan; and performance of a cybersecurity architecture design review. Compliance with these 
measures has not had a material impact on our operations. We continue to evaluate the potential effect of these directives on 
our operations and facilities and will continue to monitor for any clarifications or amendments to these directives.

Gas Pipeline and Storage Integrity and Safety

We are subject to regulation by PHMSA, which requires the following for certain gas distribution and transmission pipelines and 
underground storage facilities: inspection and maintenance plans; integrity management programs, including the determination 
of pipeline integrity risks and periodic assessments on certain pipeline segments; an operator qualification program, which 
includes certain trainings; a public awareness program that provides certain information; and a control room management plan. If 
we fail to comply with applicable statutes and the PHMSA Office of Pipeline Safety’s rules and related regulations and orders, we 
could be subject to significant penalties and fines.

Environmental Matters

We have clean energy goals to reduce GHG emissions that are based on prudent and proven solutions while minimizing cost 
impacts to and ensuring safety of our customers. See more information in Key Elements of our Business Strategy within 
Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 of this Annual Report on 
Form 10-K.

We are subject to significant state and federal environmental regulations that encourage the use of clean energy technologies 
and regulate emissions of GHGs. We have undertaken initiatives to meet current requirements and to prepare for anticipated 
future regulations, reduce GHG emissions, and respond to state renewable and energy efficiency goals. Compliance with future 
environmental regulations could result in substantial cost.

In July of 2019, the EPA adopted the Affordable Clean Energy rule, which requires states to develop plans by 2022 for GHG 
reductions from coal-fired power plants. On May 23, 2023, the EPA proposed to repeal the Affordable Clean Energy rule and at 
the same time issued a replacement rule to establish emissions limits for GHG emissions from existing coal-fired and oil/gas-
fired electric power generating boilers. The EPA also proposed GHG emission limits for existing stationary combustion turbines. 
The proposed emissions limitations are based upon the application of carbon capture controls or the use of hydrogen fuel 
beginning in 2030. The EPA is expected to issue a final rule in the first half of 2024. We will continue to monitor any related 
guidelines and rulemakings issued by the EPA or state regulatory authorities.

In February 2022, the EPA proposed the Good Neighbor Rule Provisions, which are part of the CSAPR framework and is 
intended to address ozone transport for the 2015 ozone NAAQS. The proposed rule included the state of Wyoming and imposed 
a NOx emissions trading program on fossil fueled electricity generating plants within the state. The EPA’s consideration of 
revised NOx emissions inventories and revised ozone modeling resulted in Wyoming’s exclusion from the final Good Neighbor 
Rule published on June 5, 2023. In a subsequent action published on August 14, 2023, the EPA approved Wyoming’s State 
Implementation Plan submission addressing interstate transport for the 2015 8-hour ozone NAAQS, and Wyoming sources will 
not be subject to the CSAPR.

Environmental risk changes constantly with the implementation of new or modified regulations, changing stakeholder interests 
and needs, and through the introduction of innovative work practices and technologies. We continually assess risk and develop 
mitigation strategies to manage and ensure compliance across the enterprise successfully and responsibly. For additional 
information on environmental matters, see Item 1A and Note 3 of the Notes to Consolidated Financial Statements in this Annual 
Report on Form 10-K.

ITEM 1A.       RISK FACTORS

The nature of our business subjects us to a number of uncertainties and risks. Risks that may adversely affect our business 
operations, financial condition, results of operations or cash flows are described below. These risk factors, along with other risk 
factors that we discuss in our periodic reports filed with the SEC should be considered for a better understanding of our 
Company.

STRATEGIC RISK

Our continued success is dependent on execution of our business plan and growth strategy, including our capital 
investment program.

Our continued success depends, in significant part, on our ability to execute our strategic business plans. Our strategy is 
centered on four critical priorities: Growth—to grow strategically and achieve strong financial performance, Operational 
Excellence—delivering safe, reliable and cost-effective energy to meet our customers’ needs, Transformation—be a simple and 
connected company positioned for growth, and People & Culture—retain and attract a talented, engaged and thriving team. Our 
current plans and strategy may be negatively impacted by disruptive forces and innovations in the marketplace, workforce 
capabilities, changing political, business or regulatory conditions and technology advancements.

In addition, we have significant capital investment programs planned for the next five years that are key to our strategic business 
plans. The successful execution of our capital investment program depends on, or could be affected by, a variety of factors that 
include, but are not limited to: access to capital to fund projects, weather conditions, effective management of projects, 
availability of qualified construction personnel including contractors, changes in commodity and other prices, impacts of supply 
chain disruptions on availability and cost of materials, governmental approvals and permitting, regulatory cost recovery and 
return on investment.

An inability to successfully and timely adapt to changing conditions and execute our strategic plans could materially affect our 
financial operating results including earnings, cash flow and liquidity.

REGULATORY, LEGISLATIVE AND LEGAL RISKS

We may be subject to unfavorable or untimely federal and state regulatory outcomes.

Our regulated Utilities are subject to cost-of-service/rate-of-return regulation and earnings oversight from federal and eight state 
utility commissions. This regulatory treatment does not provide any assurance as to achievement of desired earnings levels. Our 
customer rates are regulated based on an analysis of our costs and investments, as reviewed and approved in regulatory 
proceedings. While rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on 
invested capital, there can be no assurance that our various regulatory authorities will judge all of our costs to have been 
prudently incurred or that the regulatory process in which rates are determined will result in full or timely recovery of our costs 
with a reasonable return on invested capital. In addition, adverse rate decisions, including rate moratoriums, rate refunds, limits 
on rate increases, lower allowed returns on investments or rate reductions, could be influenced by competitive, economic, 
political, legislative, public perception and regulatory pressures and adversely impact earnings, cash flow and liquidity.

Each of our Utilities are permitted to recover certain costs (such as increased fuel and purchased power costs, including costs 
from certain severe weather events, or integrity capital investments) outside of a base rate review in order to stabilize customer 
rates and reduce regulatory lag. If regulators decide to discontinue these tariff-based recovery mechanisms, it could negatively 
impact earnings, cash flow and liquidity.

Costs could significantly increase to achieve or maintain compliance with existing or future environmental laws, 
regulations or requirements including those associated with climate change.

Our business segments are subject to numerous environmental laws and regulations affecting many aspects of present and 
future operations, including air emissions (i.e., SO2, NOx, volatile organic compounds, particulate matter and GHG), water 
quality, wastewater discharges, solid waste and hazardous waste.

These laws and regulations may result in increased capital, operating and other costs. These laws and regulations generally 
require the business segments to obtain and comply with a wide variety of environmental licenses, permits, inspections and 
other government approvals. Compliance with environmental laws and regulations may require significant expenditures, 
including expenditures for cleanup costs and damages arising from contaminated properties. Failure or inability to comply with 
evolving environmental regulations may result in the imposition of fines, penalties and injunctive measures affecting operating 
assets.

Our business segments may not be successful in recovering increased capital and operating costs incurred to comply with new 
environmental regulations through existing regulatory rate structures and contracts with customers. More stringent environmental 
laws or regulations could result in additional costs of operation for existing facilities or impede the development of new facilities.

There is significant uncertainty regarding if and when new climate legislation, regulations or administrative policies will be 
adopted to reduce or limit GHG and the impact any such regulations would have on us. New or more stringent regulations or 
other energy efficiency requirements could require us to incur significant additional costs relating to, among other things, the 
installation of additional emission control equipment, the acceleration of capital expenditures, the purchase of additional 
emissions allowances or offsets, the acquisition or development of additional energy supply from renewable resources, the 
closure or capacity reductions of coal-fired power generation facilities or conversion to alternative fuels, and potential increased 
production from our combined cycle natural gas-fired generating units. Additional rules and regulations associated with fossil 
fuels and GHG emissions could result in the impairment or retirement of some of our existing or future transmission, distribution, 
generation and natural gas storage facilities or our coal mine. Further, these rules could create the need to purchase or build 
clean-energy fuel sources to fulfill obligations to our customers. These actions could also result in increased operating costs 
which could adversely impact customers and our financial operating results including earnings, cash flow and liquidity. We 
cannot definitively estimate the effect of GHG legislation or regulation on our earnings, cash flow and liquidity.

Legislative and regulatory requirements may result in compliance penalties.

Business activities in the energy sector are heavily regulated, primarily by agencies of the federal government. Many agencies 
employ mandatory civil penalty structures for regulatory violations. The FERC, NERC, PHMSA, CFTC, EPA, OSHA, SEC, TSA 
and MSHA may impose significant civil and criminal penalties to enforce compliance requirements relative to our business, 
which could have a material adverse effect on our financial operating results including earnings, cash flow and liquidity.

Municipal governments may seek to limit or deny our franchise privileges.

Municipal governments within our utility service territories possess the power of condemnation and could establish a municipal 
utility within a portion of our current service territories by limiting or denying franchise privileges for our operations and exercising 
powers of condemnation over all or part of our utility assets within municipal boundaries. We regularly engage in negotiations on 
renewals of franchise agreements with our municipal governments. We have from time to time faced challenges or ballot 
initiatives on franchise renewals. To date, we have been successful in resolving or defending most of these challenges. Although 
condemnation is a process that is subject to constitutional protections requiring just and fair compensation, as with any judicial 
procedure, the outcome is uncertain. If a municipality sought to pursue this course of action, we cannot assure that we would 
secure adequate recovery of our investment in assets subject to condemnation. We also cannot quantify the impact that such 
action would have on the remainder of our business operations.

Changes in Federal tax law may significantly impact our business.

We are subject to taxation by the various taxing authorities at the federal, state and local levels where we operate. Sweeping 
legislation or regulation could be enacted by any of these governmental authorities which may affect our tax burden. Changes 
may include numerous provisions that affect businesses, including changes to corporate tax rates, business-related exclusions, 
and deductions and credits. The outcome of regulatory proceedings regarding the extent to which a change in corporate tax rate 
will affect our utility customers and the time period over which that change will occur could significantly impact future earnings 
and cash flows. Separately, a challenge by a taxing authority, changes in taxing authorities’ administrative interpretations, 
decisions, policies and positions, our ability to utilize tax benefits such as carryforwards or tax credits, or a deviation from other 
tax-related assumptions may cause actual financial results to deviate from previous estimates.

OPERATING RISKS

Failure to attract and retain an appropriately qualified workforce could have a negative impact on our operations and 
long-term business strategy.

Recent trends, such as a competitive and tight labor market and an aging workforce may lead to higher costs and increased risk 
of negative outcomes for safety, compliance, customer service, and operations. Our ability to transition and replace our 
retirement-eligible utility employees is a risk; at December 31, 2023, approximately 18% of our employees were eligible for 
retirement. Our ability to avoid or minimize work stoppages and labor disputes is also a risk with approximately 25% of our 
employees represented by unions. Failure to hire and retain qualified employees, including the ability to transfer significant 
internal historical knowledge and expertise to new employees, may adversely affect our ability to manage and operate our 
business. If we are unable to successfully attract and retain an appropriately qualified workforce and maintain satisfactory 
collective bargaining agreements, safety, service reliability, customer satisfaction and our results of operations could be 
adversely affected. As part of our strategic business plans, we will need to attract and retain personnel who are qualified to 
implement our strategy and may need to retrain or re-skill certain employees to support our long-term objectives.

Supply chain challenges could negatively impact our operations.

We rely on various suppliers in our supply chain for the materials necessary to execute on our capital investment program that is 
key to our strategic business plans and to respond to a significant unplanned event such as a natural disaster. Our largest 
customers also rely on our supply chain and delays in critical materials could impact their ability to operate and grow as planned. 
Our supply chain, material costs, and capital investment program may be negatively impacted by:

•

•

Unanticipated price increases due to recent macroeconomic factors, such as inflation, including wage inflation, or 
rising demand for raw materials associated with the Energy Transition; and

Supply restrictions beyond our control or the control of our suppliers such as disruption of the freight system (e.g. 
labor union strikes), increased environmental threats from weather-related disasters, rising demand for raw 
materials associated with the Energy Transition and/or geopolitical unrest (e.g. Russia-Ukraine and Middle East 
conflicts).

An inability to successfully manage challenges in our supply chain network could materially affect our ability to execute our 
business plan and growth strategy and our financial operating results including earnings, cash flow and liquidity.

Our financial performance depends on the successful operation of electric generating facilities, electric and natural gas 
transmission and distribution systems, natural gas storage facilities and a coal mine.

The risks associated with managing these operations include:

•

•

•

•

•

•

•

Operating hazards. Operating hazards such as leaks, mechanical problems and accidents, including fires or 
explosions, could impact employee and public safety, reliability and customer confidence;

Inherent dangers. Electricity and natural gas can be dangerous to employees and the general public. Failures of or 
contact with power lines, natural gas pipelines or service facilities and equipment may result in fires, explosions, 
property damage and personal injuries, including death. While we maintain liability and property insurance coverage, 
such policies are subject to certain limits and deductibles. The occurrence of any of these events may not be fully 
covered by our insurance;

Weather, natural conditions and disasters including impacts from climate change (discussed below);

Acts of sabotage, terrorism or other malicious physical attacks. Damage to our facilities due to deliberate acts could 
lead to outages or other adverse effects;

Equipment and processes. Breakdown or failure of equipment or processes, unavailability or increased cost of 
equipment, and performance below expected levels of output or efficiency could negatively impact our results of 
operations;

Disrupted transmission and distribution. We depend on transmission and distribution facilities, including those 
operated by unaffiliated parties, to deliver the electricity and natural gas that we sell to our retail and wholesale 
customers. If transmission is interrupted physically, mechanically or with cyber means, our ability to sell or deliver 
utility services and satisfy our contractual obligations may be hindered;

Natural gas supply for generation and distribution. Our regulated Utilities and non-regulated entities purchase 
natural gas from a number of suppliers for our generating facilities and for distribution to our customers. Our results 
of operations could be negatively impacted by the lack of availability and cost of natural gas, and disruptions in the 
delivery of natural gas due to various factors, including but not limited to, transportation delays, labor relations, 
weather, sabotage, cyber-attacks and environmental regulations;

•

Replacement power. The cost of supplying or securing replacement power during scheduled and unscheduled 
outages of generation facilities could negatively impact our results of operations;

Governmental permits. The inability to obtain required governmental permits and approvals along with the cost of 
complying with or satisfying conditions imposed upon such approvals could negatively impact our ability to operate 
and our results of operations;

Operational limitations. Operational limitations imposed by environmental and other regulatory requirements and 
contractual agreements, including those that restrict the timing of generation plant scheduled outages, could 
negatively impact our results of operations;

Increased costs. Increased capital and operating costs to comply with increasingly stringent laws and regulations, 
unexpected engineering, environmental and geological problems, and unanticipated cost overruns could negatively 
impact our results of operations;

Supply chain challenges (discussed above);

Workforce capabilities and labor relations (discussed above); and

Public opposition. Opposition by members of public or special-interest groups could negatively impact our ability to 
operate our businesses.

Any of these risks described above could damage our reputation and public confidence. These risks could also cause us to incur 
significant costs or be unable to deliver energy and/or operate below expected capacity levels, which in turn could reduce 
revenues or cause us to incur higher operating and maintenance costs and penalties. While we maintain insurance, obtain 
warranties from vendors and obligate contractors to meet certain performance levels, the proceeds of such insurance and our 
rights under contracts, warranties or performance guarantees may not be timely or adequate to cover lost revenues, increased 
expenses, liability or liquidated damage payments.

The nature of our business subjects us to climate-related risk, stemming from both physical risk and transition risk of 
climate change, over varying time horizons.

Physical risks of climate change refer to risks to our facilities or operations that may result from changes in the physical climate, 
such as changes to temperature and weather patterns. Our utility businesses are seasonal businesses and weather conditions 
and patterns can have a material impact on our operating results. To the extent weather conditions are affected by climate 
change, fluctuations in commodity prices and customers’ energy usage could be magnified. Climate change may lead to 
increased intensity and frequency of storms, resulting in increased likelihood of fire, wind and extreme temperature events. 
Severe weather events, such as snow and ice storms (e.g., Winter Storm Uri), fire, and strong winds could negatively impact our 
operations, including our ability to provide energy safely, reliably and profitably and our ability to complete construction, 
expansion or refurbishment of facilities as planned. Climate change may intensify these events or increase the frequency of their 
occurrence. Over time, we may need to make additional investments to protect our facilities from physical risks of climate 
change.

Transition risks of climate change include changes to the energy systems as a result of new technologies, changing customer 
demand and/or expectations and voluntary GHG reduction goals, as well as local, state or federal regulatory requirements 
(discussed above). Policies such as a carbon or methane tax could increase costs associated with fossil fuel usage, resulting in 
higher operating costs including costs of energy generation, construction, and transportation. Risks of the transition to a low-
carbon economy could result in shrinking customer demand for fossil fuel-based energy sources. This could come from 
increased use of behind the meter technology, such as residential solar and storage. Risk of investor pressure over climate risk 
and/or ESG standards, activist campaigns against coal producers, employee preferences to work for companies with certain 
sustainability goals and consumers preference for renewable energy could impact our reputation, ability to attract and retain an 
appropriately trained workforce, and overall access to capital and/or adequate insurance policies.

Replacement power. The cost of supplying or securing replacement power during scheduled and unscheduled 

outages of generation facilities could negatively impact our results of operations;

Cybersecurity incidents, terrorism, or other malicious acts targeting our key technology systems could disrupt our 
operations or lead to a loss or misuse of confidential and proprietary information.

To effectively operate our business, we rely upon a sophisticated electronic control system, information and operation 
technology systems and network infrastructure to generate, distribute and deliver energy, and collect and retain sensitive 
information including personal information about our customers and employees. Cybersecurity incidents, terrorism or other 
malicious acts targeting electronic control systems could result in a full or partial disruption of our electric and/or natural gas 
operations. Attacks targeting other key technology systems, including our third-party vendors’ information systems, could further 
add to a full or partial disruption of our operations. The utility industry has been the target of several cyberattacks on operational 
systems and has seen an increased volume and sophistication of cybersecurity incidents from international activist 
organizations, other nation state actors and individuals. To date, we have not experienced a cybersecurity incident that has had 
a material impact on our business or results of operations. Any disruption of our electric and/or natural gas operations could 
result in a loss of service to customers and associated revenues, as well as significant expense to repair damages and remedy 
security breaches. In addition, any theft, loss and/or fraudulent use of customer, shareowner, employee or proprietary data could 
subject us to significant litigation, liability and costs, as well as adversely impact our reputation with customers and regulators, 
among others. We maintain cyber risk insurance to mitigate a portion, but not all, of these risks and losses.

As discussed in Utility Regulation Characteristics above, in 2021 the TSA issued security directives that included several new 
cybersecurity requirements for critical pipeline owners and operators. Such directives or other requirements may require 
expenditure of significant additional resources to respond to cybersecurity incidents, to continue to modify or enhance protective 
measures, or to assess, investigate and remediate any critical infrastructure security vulnerabilities. Any failure to comply with 
such government regulations or failure in our cybersecurity protective measures may result in enforcement actions that may 
have a material adverse effect on our business, results of operations and financial condition. In addition, there is no certainty that 
costs incurred related to securing against threats will be recovered through rates.

As discussed in Item 1C in this Annual Report on Form 10-K, we have instituted security measures and safeguards to protect 
our operational systems and information technology assets against cybersecurity threats, including certain safeguards required 
by NERC. Despite our implementation of security measures and safeguards, all of our technology systems may still be 
vulnerable to disability, failures or unauthorized access.

Our operations are subject to various conditions that can result in fluctuations in customer usage, including customer 
growth and general economic conditions in our service territories, weather conditions, and responses to price 
increases and technological improvements.

Our results of operations and cash flows are affected by the demand for electricity and natural gas, which can vary greatly based 
upon:

•

•

Fluctuations in customer growth and general economic conditions in our service territories. Customer growth and 
energy use can be negatively impacted by population declines as well as adverse economic factors in our service 
territories, including recession, inflation, workforce reductions, stagnant wage growth, changing levels of support 
from state and local government for economic development, business closings, and reductions in the level of 
business investment. Our Utilities are impacted by economic cycles and the competitiveness of the commercial and 
industrial customers we serve. Any economic downturn, inflation, disruption of financial markets, or reduced 
incentives by state government for economic development could adversely affect the financial condition of our 
customers and demand for their products or services. These risks could directly influence the demand for electricity 
and natural gas as well as the need for additional power generation and generating facilities. We could also be 
exposed to greater risks of accounts receivable write-offs if customers are unable to pay their bills.

Weather conditions. Our Utilities are seasonal businesses and weather conditions and patterns can have a material 
impact on our operating performance. Demand for electricity is typically greater in the summer and winter months 
associated with cooling and heating, respectively. Demand for natural gas depends heavily upon winter-weather 
patterns throughout our service territory and a significant amount of natural gas revenues are recognized in the first 
and fourth quarters related to the heating season. Accordingly, our Utilities have historically generated lower 
revenues, income and cash flows when weather conditions are cooler than normal in the summer and warmer than 
normal in the winter. Demand for natural gas is also impacted by summer weather patterns that are cooler than 
normal and provide higher than normal precipitation; both of which can reduce natural gas demand for irrigation. 
Unusually mild summers and winters, therefore, could have an adverse effect on our financial operating results, 
including earnings, cash flow and liquidity.

27

10-KFORM 10-K  |•

Our customers' focus on energy conservation. Customer growth and usage may be impacted by the voluntary 
reduction in consumption of electricity and natural gas by our customers in response to increases in prices and 
energy efficiency programs, electrification initiatives that could negatively impact the demand for natural gas, 
economic conditions (i.e., inflation, recession) impacting customers’ disposable income and the use of distributed 
generation resources or other emerging technologies. Continued technological improvements may make customer 
and third-party distributed generation and energy storage systems, including fuel cells, micro-turbines, wind turbines, 
solar cells and batteries, more cost effective and feasible for our customers. If more customers utilize their own 
generation, demand for energy from us could decline. Such developments could affect the price and/or delivery of 
energy, require further improvements to our distribution systems to address changing load demands and could 
make portions of our electric system power supply and transmission and/or distribution facilities obsolete prior to the 
end of their useful lives.

Each of these factors described above could materially affect demand for electricity and natural gas which would impact our 
financial operating results including earnings, cash flow and liquidity.

If macroeconomic or other conditions adversely affect operations or require us to make changes to our strategic 
business plan, we may be forced to record a non-cash goodwill impairment charge.

We had approximately $1.3 billion of goodwill on our consolidated balance sheets as of December 31, 2023. If we make 
changes in our strategic business plan and growth strategy, or if macroeconomic or other conditions adversely affect operations 
in any of our businesses, we may be required to record a non-cash impairment charge. Goodwill is tested for impairment 
annually or whenever events or changes in circumstances indicate impairment may have occurred. If the testing performed 
indicates that impairment has occurred, we are required to record an impairment charge for the difference between the carrying 
value of the goodwill and the implied fair value of the goodwill in the period the determination is made. The testing of goodwill for 
impairment requires us to make significant estimates about our future performance and cash flows, as well as other 
assumptions. These estimates can be affected by numerous factors, including: future business operating performance, changes 
in macroeconomic conditions including recession, inflation and interest rates, changes in our regulatory environment, industry-
specific market conditions, changes in business operations, changes in competition or changes in technologies. Any changes in 
key assumptions, or actual performance compared with key assumptions, about our business and its future prospects could 
affect the fair value of either or both of our operating segments, which may result in an impairment charge. See additional 
information in “Critical Accounting Estimates” under Item 7, Management’s Discussion and Analysis of Financial Condition and 
Results of Operations and Note 1 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

FINANCIAL RISKS

A sub-investment grade credit rating could impact our ability to access capital markets.

Our senior unsecured debt rating is Baa2 (Stable outlook) by Moody’s; BBB+ (Stable outlook) by S&P; and BBB+ (Negative 
outlook) by Fitch. Reduction of our investment grade credit ratings could impair our ability to refinance or repay our existing debt 
and complete new financings on reasonable terms. A credit rating downgrade, particularly to sub-investment grade, could also 
result in counterparties requiring us to post additional collateral under existing or new contracts. In addition, a ratings downgrade 
would increase our interest expense under some of our existing debt obligations, including borrowings under our credit facilities, 
potentially significantly increasing our cost of capital and other associated operating costs which may not be recoverable through 
existing regulatory rate structures and contracts with customers.

We may be unable to obtain financing on reasonable terms needed to refinance debt, fund planned capital expenditures 
or otherwise execute our operating strategy.

Our ability to execute our operating strategy is highly dependent upon our access to capital. Historically, we have addressed our 
liquidity needs (including funds required to make scheduled principal and interest payments, refinance debt, pay dividends and 
fund working capital and planned capital expenditures) with operating cash flow, borrowings under credit facilities, proceeds of 
debt and equity offerings and proceeds from asset sales. Our ability to access capital markets and the costs and terms of 
available financing depend on many factors, including changes in our credit ratings, general macroeconomic conditions which 
may drive changes in interest rates and cause volatility in our stock price, changes in the federal or state regulatory environment 
affecting energy companies and volatility in commodity prices.

In addition, because we are a holding company and our utility assets are owned by our subsidiaries, if we are unable to 
adequately access the credit markets, we could be required to take additional measures designed to ensure that our utility 
subsidiaries are adequately capitalized to provide safe and reliable service. Possible additional measures would be evaluated in 
the context of then-prevailing market conditions, prudent financial management and any applicable regulatory requirements.

make portions of our electric system power supply and transmission and/or distribution facilities obsolete prior to the 

end of their useful lives.

The costs of providing healthcare benefits to our employees and retirees have increased substantially in recent years. We 
believe that our employee benefit costs, including costs related to healthcare plans for our employees and former employees, 
will continue to rise. Significant regulatory developments have required, and likely will continue to require, changes to our current 
employee benefit plans and supporting administrative processes. Our electric and natural gas utility rates are regulated on a 
state-by-state basis by the relevant state regulatory authorities based on an analysis of our costs, as reviewed and approved in a 
regulatory proceeding. Within our utility rates, we have generally recovered the cost of providing employee benefits. As benefit 
costs continue to rise, however, there is no assurance that the utility commissions will allow recovery of these increased costs. 
The rising employee benefit costs, or inadequate recovery of such costs, may adversely affect our financial operating results 
including earnings, cash flow, and liquidity.

Each of these factors described above could materially affect demand for electricity and natural gas which would impact our 

financial operating results including earnings, cash flow and liquidity.

We may be unable to obtain insurance coverage, and the coverage we currently have may not apply or may be 
insufficient to cover a significant loss.

If macroeconomic or other conditions adversely affect operations or require us to make changes to our strategic 

business plan, we may be forced to record a non-cash goodwill impairment charge.

We had approximately $1.3 billion of goodwill on our consolidated balance sheets as of December 31, 2023. If we make 

changes in our strategic business plan and growth strategy, or if macroeconomic or other conditions adversely affect operations 

in any of our businesses, we may be required to record a non-cash impairment charge. Goodwill is tested for impairment 

annually or whenever events or changes in circumstances indicate impairment may have occurred. If the testing performed 

indicates that impairment has occurred, we are required to record an impairment charge for the difference between the carrying 

value of the goodwill and the implied fair value of the goodwill in the period the determination is made. The testing of goodwill for 

impairment requires us to make significant estimates about our future performance and cash flows, as well as other 

assumptions. These estimates can be affected by numerous factors, including: future business operating performance, changes 

in macroeconomic conditions including recession, inflation and interest rates, changes in our regulatory environment, industry-

specific market conditions, changes in business operations, changes in competition or changes in technologies. Any changes in 

key assumptions, or actual performance compared with key assumptions, about our business and its future prospects could 

affect the fair value of either or both of our operating segments, which may result in an impairment charge. See additional 

information in “Critical Accounting Estimates” under Item 7, Management’s Discussion and Analysis of Financial Condition and 

Results of Operations and Note 1 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

FINANCIAL RISKS

A sub-investment grade credit rating could impact our ability to access capital markets.

Our senior unsecured debt rating is Baa2 (Stable outlook) by Moody’s; BBB+ (Stable outlook) by S&P; and BBB+ (Negative 

outlook) by Fitch. Reduction of our investment grade credit ratings could impair our ability to refinance or repay our existing debt 

and complete new financings on reasonable terms. A credit rating downgrade, particularly to sub-investment grade, could also 

result in counterparties requiring us to post additional collateral under existing or new contracts. In addition, a ratings downgrade 

would increase our interest expense under some of our existing debt obligations, including borrowings under our credit facilities, 

potentially significantly increasing our cost of capital and other associated operating costs which may not be recoverable through 

existing regulatory rate structures and contracts with customers.

We may be unable to obtain financing on reasonable terms needed to refinance debt, fund planned capital expenditures 

or otherwise execute our operating strategy.

Our ability to execute our operating strategy is highly dependent upon our access to capital. Historically, we have addressed our 

liquidity needs (including funds required to make scheduled principal and interest payments, refinance debt, pay dividends and 

fund working capital and planned capital expenditures) with operating cash flow, borrowings under credit facilities, proceeds of 

debt and equity offerings and proceeds from asset sales. Our ability to access capital markets and the costs and terms of 

available financing depend on many factors, including changes in our credit ratings, general macroeconomic conditions which 

may drive changes in interest rates and cause volatility in our stock price, changes in the federal or state regulatory environment 

affecting energy companies and volatility in commodity prices.

In addition, because we are a holding company and our utility assets are owned by our subsidiaries, if we are unable to 

adequately access the credit markets, we could be required to take additional measures designed to ensure that our utility 

subsidiaries are adequately capitalized to provide safe and reliable service. Possible additional measures would be evaluated in 

the context of then-prevailing market conditions, prudent financial management and any applicable regulatory requirements.

Our ability to obtain insurance, as well as the cost of such insurance, could be impacted by developments affecting the insurance 
industry and the financial condition of insurers. Additionally, insurance providers could deny coverage or decline to extend 
coverage under the same or similar terms that are presently available to us. A loss for which we are not adequately insured 
could materially affect our financial results. The coverage we currently have in place may not apply to a particular loss, or it may 
not be sufficient to cover all liabilities to which we may be subject, including liability and losses associated with wildfires, natural 
gas and storage field explosions, cyber-security breaches, environmental hazards and natural disasters.

We have a holding company corporate structure with multiple subsidiaries.  Corporate dividends and debt payments 
are dependent upon cash distributions to the holding company from the subsidiaries.

As a holding company, our investments in our subsidiaries are our primary assets. Our operating cash flow and ability to service 
our indebtedness depend on the operating cash flow of our subsidiaries and the payment of funds by them to us in the form of 
dividends or advances. Our subsidiaries are separate legal entities that have no obligation to make any funds available for that 
purpose, whether by dividends or otherwise. In addition, each subsidiary’s ability to pay dividends to us depends on any 
applicable contractual or regulatory restrictions that may include requirements to maintain minimum levels of cash, working 
capital, equity or debt service funds.

There is no assurance as to the amount, if any, of future dividends to the holding company because these subsidiaries depend 
on future earnings, capital requirements and financial conditions to fund such dividends. See “Liquidity and Capital Resources” 
within Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 and Note 8 of the 
Notes to Consolidated Financial Statements of this Annual Report on Form 10-K for further information regarding these 
restrictions and their impact on our liquidity.

Market performance or changes in key valuation assumptions could require us to make significant unplanned 
contributions to our pension plan and other postretirement benefit plans.

Assumptions related to interest rates, expected return on investments, mortality and other key actuarial assumptions have a 
significant impact on our funding requirements and the expense recognized related to our pension and other postretirement 
benefit plans. An adverse change to key assumptions associated with our defined benefit retirement plans may require 
significant unplanned contributions to the plans which could adversely affect our financial operating results including earnings, 
cash flow and liquidity. See Note 13 of the Notes to Consolidated Financial Statements of this Annual Report on Form 10-K for 
further information

Our use of derivative financial instruments as hedges against commodity prices and financial market risks could result 
in material financial losses.

We use various financial and physical derivatives, including futures, forwards, options and swaps, to manage commodity price 
and interest rate risks. The timing of the recognition of gains or losses on these economic hedges in accordance with GAAP may 
not consistently match up with the gains or losses on the commodities being hedged. For Black Hills Energy Services under the 
Choice Gas Program, and in certain instances within our regulated Utilities where unrealized and realized gains and losses from 
derivative instruments are not approved for regulatory accounting treatment, fluctuating commodity prices may cause 
fluctuations in reported financial results due to mark-to-market accounting treatment.

To the extent that we hedge our commodity price and interest rate exposures, we forgo the benefits we would otherwise 
experience if commodity prices or interest rates were to change in our favor. In addition, even though they are closely monitored 
by management, our hedging activities can result in losses. Such losses could occur under various circumstances, including if a 
counterparty does not perform its obligations under the hedge arrangement, the hedge is economically imperfect, commodity 
prices or interest rates move unfavorably related to our physical or financial positions, or hedging policies and procedures are 
not followed.

29

10-KFORM 10-K  |Additionally, our exchange-traded futures contracts are subject to futures margin posting requirements. To the extent we are 
unable to meet these requirements, this could have a significant impact on our business by reducing our ability to execute 
derivative transactions to reduce commodity price uncertainty and to protect cash flows. Requirements to post collateral may 
cause significant liquidity issues by reducing our ability to use cash for investment or other corporate purposes or may require us 
to increase our level of debt. Further, a requirement for our counterparties to post collateral could result in additional costs being 
passed on to us, thereby decreasing our profitability.

ITEM 1C.       CYBERSECURITY

The utility industry has been the target of several cyberattacks on operational systems and has seen an increased volume and 
sophistication of cybersecurity incidents from international activist organizations, other nation state actors and individuals. We 
expect to continue to experience attempts to compromise our information technology and control systems, network infrastructure 
and other assets. To date, we have not experienced a cybersecurity incident that has had a material impact on our business or 
results of operations.

Risk Management and Strategy

Our enterprise risk management program, which includes cybersecurity risks that are identified through our cybersecurity risk 
management program, is designed to identify, report, and manage relevant material risks and opportunities. 
Management of the identified risks is embedded into business processes and key decision making at every level of the 
Company. Our enterprise risk management team works closely with our Chief Security Officer ("CSO") and IT risk management 
team to evaluate and address material cybersecurity risks in alignment with our business strategy and operational needs.

We have a cybersecurity risk management program that is managed by a team of full-time cybersecurity professionals that 
utilizes a variety of tools and techniques to identify and assess material cybersecurity threats, their potential impact and 
opportunities for mitigation. The industry-standard security frameworks that we apply to our cyber environment include various 
security and risk assessments, such as internal threat assessments and internal control self-assessments. Because we are 
aware of the risks associated with third-party providers, we conduct third-party provider security assessments and benchmarking 
before engagement and maintain ongoing monitoring to ensure compliance with our cybersecurity standards. These 
assessments include evaluation of risk profiles through vendor questionnaires, review of System and Organization Controls 
attestation reports and monitoring on an ongoing basis by our IT risk management team. This approach is designed to mitigate 
risks related to data breaches or other security incidents originating from third-parties.

We regularly engage with third-party assessors and auditors as part of our ongoing cybersecurity risk assessment process to 
leverage specialized knowledge and insights and to identify areas for continued focus, improvement, compliance and 
effectiveness of mitigation. We also utilize government and industry-related security intelligence sources, and actively participate 
in industry peer groups and public-private partnerships to assist in the identification of potential threats. We conduct ongoing 
cybersecurity training and monthly email phishing drills for all employees.

We also have a cybersecurity incident response plan and procedures to manage cybersecurity incidents. These procedures 
include steps to identify, classify, communicate, contain, eradicate, and recover from a cybersecurity incident. These procedures 
also include notification to a cross-functional management team to assess incident materiality and an escalation process to 
members of our senior management team and our Board of Directors.

Governance

Our Board of Directors is responsible for the oversight of risks from cybersecurity threats. Our Chief Information Officer provides 
our Board of Directors quarterly reports that summarize material cybersecurity threats and the countermeasures taken to 
mitigate the associated risks. These reports address a variety of topics including updates on strategic cyber initiatives, industry 
trends, threat vulnerability assessments, and efforts to prevent, detect and respond to internal and external critical threats. From 
time to time, our Board of Directors also engages third-party consultants to provide further education about cybersecurity risks.

Our cybersecurity risk management program, which is discussed above, is led by our CSO, who has 28 years of prior work 
experience in various roles involving managing information security of large-scale global security operations, including 
developing cybersecurity strategy and implementing effective information and cybersecurity programs. Our CSO maintains 
industry certifications, including an ISC2 Certified Information Systems Security Professional certification.

ITEM 7.      MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Executive Summary

We are a customer-focused energy solutions provider with a mission of Improving Life with Energy for more than 1.3 million 
customers and 800+ communities we serve. Our aspiration is to be the trusted energy partner across our growing eight-state 
footprint, including Arkansas, Colorado, Iowa, Kansas, Montana, Nebraska, South Dakota and Wyoming. Our strategy is 
centered on four critical priorities: Growth—to grow strategically and achieve strong financial performance, Operational 
Excellence—delivering safe, reliable and cost-effective energy to meet our customers’ needs, Transformation—be a simple and 
connected company positioned for growth, and People & Culture—retain and attract a talented, engaged and thriving team.

We conduct our business operations through two operating segments: Electric Utilities and Gas Utilities. Certain unallocated 
corporate expenses that support our operating segments are presented as Corporate and Other. We conduct our utility 
operations under the name Black Hills Energy predominantly in rural areas of the Rocky Mountains and Midwestern states. We 
consider ourself a domestic electric and natural gas utility company.

We have provided energy and served customers for 140 years, since the 1883 gold rush days in Deadwood, South Dakota. 
Throughout our history, the common thread that unites the past to the present is our commitment to serve our customers and 
communities. By being responsive and service focused, we can help our customers and communities thrive while meeting 
rapidly changing customer expectations.

Key Elements of our Business Strategy

Explore opportunities as an energy solutions provider.  A key strategic initiative is to grow our business through innovative 
energy solutions with new customers and partnerships. We see value creation by recruiting new customers and expanding 
existing partnerships with data centers and blockchain opportunities; exploring energy markets such as RTOs; and expanding 
our transmission capabilities, establishing a RNG program and expanding our RNG portfolio. A few recent examples of our 
initiatives to grow our business as an energy solutions provider include:

•

•

•

•

Contracted Renewable Energy to Grow Data Center Partnerships: In 2022, Wyoming Electric entered into two new 
PPAs with third parties to purchase up to 106 MW of wind energy and up to 150 MW of solar energy, upon 
construction of new renewable generation facilities (owned by third parties). The new wind generation facility was 
placed in service in December 2023 and the solar facility is expected to be completed in March 2024. The 
renewable energy from these PPAs will be used to serve our expanding partnerships with data centers.

Developed BCIS Tariff to Facilitate Growth: We have supported enabling legislation in Wyoming for the growing 
blockchain businesses while implementing our own BCIS Tariff to serve these customers. In June 2022, Wyoming 
Electric completed its first agreement, with a new customer in Cheyenne, Wyoming, under this Tariff. This five-year 
agreement provides delivery of up to 45 MW with an option to expand service up to 75 MW, which was exercised by 
the customer in 2023. Energy is sourced through the electric energy market and delivered through our Electric 
Utilities’ infrastructure. Under the agreement, the customer is responsible for costs of service, and the load is 
interruptible to prioritize the needs of Wyoming Electric’s existing retail customers.

Established Green Forward: In 2022 and 2023, we filed regulatory applications to launch Green Forward, a 
voluntary RNG and carbon offset program, to eligible residential and small business natural gas customers to offset 
up to 100% or more of the emissions from their natural gas usage. Our teams continue to evaluate attractive RNG 
investment opportunities across our agriculture-rich service territories and explore value generation with our natural 
gas storage assets. We also continue to expand our RNG interconnections, with seven projects actively injecting 
RNG into our natural gas system.

Expanded RNG Portfolio: In January 2024, Black Hills Energy Renewable Resources acquired a RNG production 
facility at a landfill in Dubuque, Iowa. The facility currently injects RNG into the natural gas distribution system 
serving Dubuque, which is owned and operated by Iowa Gas. This acquisition represents our entry into the 
production of RNG as a nonregulated business while leveraging our expertise in owning and operating regulated 
natural gas pipeline systems, including RNG interconnections. The RNG produced from the landfill facility captures 
methane that would otherwise vent into the atmosphere. It is delivered under long-term contracts to a third party that 
purchases the RNG and its related environmental attributes, in conformity with the EPA's Renewable Fuel Standard 
Program.

Modernize and operate utility infrastructure to provide customers with safe, reliable, cost-effective electric and natural 
gas service. Our utilities own and operate large electric and natural gas infrastructure systems with a geographic footprint that 
spans nearly 1,600 miles. Our Electric Utilities own and operate 1,394 MW of generation capacity and 9,106 miles of 
transmission and distribution lines and our Gas Utilities own and operate approximately 47,000 miles of natural gas transmission 
and distribution pipelines.

A key strategic focus is to modernize and harden our utility infrastructure to meet customers’ and communities’ varied energy 
needs, ensure the continued delivery of safe, reliable and cost-effective energy and reduce GHG emissions intensity. In addition, 
we invest in the expansion, capacity and integrity of our systems to meet customer growth.

To meet our electric customers’ continued expectations of high levels of reliability, a key strength of the Company, our Electric 
Utilities utilize an integrity program to ensure the timely repair and replacement of aging infrastructure. In alignment with this 
program, in November 2021, Wyoming Electric announced its Ready Wyoming electric transmission expansion initiative. The 
260-mile, multi-phase transmission expansion project will provide customers long-term price stability and greater flexibility as 
power markets develop in the Western States. Construction of the project commenced in late 2023 and is expected to take place 
in multiple phases or segments through 2025 and will interconnect South Dakota Electric’s and Wyoming Electric’s transmission 
systems.

Our Gas Utilities utilize a programmatic approach to system-wide pipeline replacement, particularly in high consequence areas. 
Under the programmatic approach, obsolete, at-risk and vintage materials are replaced in a proactive and systematic time frame. 
We have removed all cast- and wrought-iron from our natural gas transmission and distribution systems and continue to replace 
aging infrastructure through programs that prioritize safety and reliability for our customers. Our Gas Utilities are authorized to 
use system safety, integrity and replacement cost recovery mechanisms that provide for customer rate adjustments, between 
rate reviews, which allow timely recovery of costs incurred in repairing and replacing the gas delivery systems with a return on 
the investment.

Explore opportunities as an energy solutions provider.  A key strategic initiative is to grow our business through innovative 

energy solutions with new customers and partnerships. We see value creation by recruiting new customers and expanding 

existing partnerships with data centers and blockchain opportunities; exploring energy markets such as RTOs; and expanding 

our transmission capabilities, establishing a RNG program and expanding our RNG portfolio. A few recent examples of our 

initiatives to grow our business as an energy solutions provider include:

•

•

•

•

Contracted Renewable Energy to Grow Data Center Partnerships: In 2022, Wyoming Electric entered into two new 

PPAs with third parties to purchase up to 106 MW of wind energy and up to 150 MW of solar energy, upon 

construction of new renewable generation facilities (owned by third parties). The new wind generation facility was 

placed in service in December 2023 and the solar facility is expected to be completed in March 2024. The 

renewable energy from these PPAs will be used to serve our expanding partnerships with data centers.

Developed BCIS Tariff to Facilitate Growth: We have supported enabling legislation in Wyoming for the growing 

blockchain businesses while implementing our own BCIS Tariff to serve these customers. In June 2022, Wyoming 

Electric completed its first agreement, with a new customer in Cheyenne, Wyoming, under this Tariff. This five-year 

agreement provides delivery of up to 45 MW with an option to expand service up to 75 MW, which was exercised by 

the customer in 2023. Energy is sourced through the electric energy market and delivered through our Electric 

Utilities’ infrastructure. Under the agreement, the customer is responsible for costs of service, and the load is 

interruptible to prioritize the needs of Wyoming Electric’s existing retail customers.

Projects are being evaluated by our segments for timing, cost and other factors.

Efficiently plan, construct and operate power generation facilities to serve our Electric Utilities. We best serve customers 
and communities when generation is vertically integrated into our Electric Utilities and we retain control of the fuel source. This 
business model remains a core strength and strategy today as we invest in and operate efficient power generation resources to 
supply cost-effective electricity to our customers. These generation assets can be rate-based or non-regulated assets within our 
Electric Utilities segment. However, we believe that generation assets that are rate-based provide the most effective long-term 
benefits to customers.

Our power production strategy focuses on low-cost construction and efficient operation of our generating facilities. Our low 
power production costs result from a variety of factors including low fuel costs (operations located near energy hubs), efficiency 
in converting fuel into energy and low per unit operating and maintenance costs. In addition, we operate our plants with high 
levels of Availability as compared to industry benchmarks.

Rate-Based Generation: We continue to believe that customers are best served when the power generation facilities are owned 
and rate-based by our Electric Utilities. Rate-based generation assets offer several advantages for customers and shareholders, 
including:

•

•

•

•

When generating assets are included in the utility rate base and reviewed and approved by government authorities, 
customer rates are more stable and predictable, and typically less expensive in the long run; especially when 
compared to power otherwise purchased from the open market through wholesale contracts or PPAs that are 
periodically re-priced to reflect current and varying market conditions;

Regulators participate in a planning process where long-term investments are designed to match long-term energy 
demand;

The lower-risk profile of rate-based generation assets contributes to stronger credit ratings which, in turn, can benefit 
both customers and investors by lowering the cost of capital; and

Investors are provided a long-term and stable return on their investment.

Integrated Generation: Our Electric Utilities segment also includes a power generation business that owns non-regulated 
generating facilities that are contracted through long-term power purchase agreements with our electric utilities. Our power 
generation business has an experienced staff with significant expertise in planning, building and operating power plants. This 
team also provides shared services to our Electric Utilities’ generation facilities, resulting in efficient management of all of the 
Company’s generation assets. Our power generation business competitively bids for energy and capacity through requests for 
proposals by our Electric Utilities for energy resources necessary to serve customers. This business can bid competitively due to 
construction expertise, fuel supply advantages and by co-locating new plants at our existing Electric Utilities’ energy complexes, 
reducing infrastructure and operating costs. All power plants within this business are contracted to our Electric Utilities under 
long-term contracts, located at our utility-generating complexes and physically integrated into our Electric Utilities’ operations.

Generation Fuel Supply: Our generating facilities are strategically located close to energy hubs that help reduce fuel supply 
costs. Our Colorado and Wyoming gas-fired generating facilities are located close to major natural gas energy hubs that provide 
trading liquidity and transparent pricing. Due to their location in the resource rich areas of Colorado and Wyoming, natural gas 
supply to fuel our gas-fired generation can be sourced at competitive prices. Our coal-fired power plants, all located at the 
Gillette Energy Complex in northeastern Wyoming, are supplied by our adjacent WRDC coal mine. WRDC provides 
approximately 3.7 million tons of low-sulfur coal directly to these power plants via a conveyor belt system, minimizing 
transportation costs. The fuel can be delivered to our adjacent power plants at very cost competitive prices (i.e., $1.14 per 
MMBtu for year ended December 31, 2023) when compared to alternatives. Nearly all the mine’s production is sold to these on-
site generation facilities under long-term supply contracts. Approximately one-half of our production is sold under cost-plus 
contracts with affiliates. A small portion of the mine’s production is sold to off-site industrial customers and delivered by truck.

Supporting the Energy Transition by proactively integrating alternative and renewable energy into our utility energy 
supply while mitigating customer rate impacts. A critical component of our strategy involves sustainable operations and 
supporting the Energy Transition. How we operate our company for the social good has never been more important. We are 
committed to cleaner energy and a low carbon future, integrating the Energy Transition and more renewable energy into our 
overall strategy and decision making. In addition, we are committed to a more sustainable future by better managing our impacts 
to the planet, whether that is water usage, recycling, biodiversity, or other important measures.

In November 2020, we announced clean energy goals to reduce GHG emissions intensity for our Electric Utilities by 40% by 
2030 and 70% by 2040 and achieve GHG reductions of 50% by 2035 for our Gas Utilities. Our goals are compared to a 2005 
baseline. Electric Utility goals include Scope 1 emissions from electric utility generating units and Scope 3 emissions from 
purchased power for sales. Our Gas Utilities goal initially included only Scope 1 emissions from distribution system main and 
service lines. In August 2022, we announced a new "Net Zero by 2035" target for our Gas Utilities, which doubled the previous 
target of a 50% reduction by 2035 and expanded the scope of the goal to all Scope 1 sources of methane emissions on our 
distribution system. Net Zero will be achieved through pipeline material and main replacements, advanced leak detection, third-
party damage reduction, expanding the use of RNG and hydrogen, and utilizing carbon credit offsets.

Since 2005, we have reduced GHG emissions intensity from our Electric Utilities by one-third. We have plans in place today, 
without reliance on future technologies, to achieve our corporate climate goals calling for a 40% reduction in greenhouse gas 
emissions intensity from our electric utility operations by 2030 and 70% by 2040. Additionally, our Electric Utilities have reduced 
nitrogen oxide and sulfur dioxide emissions by more than 75% since 2005. Colorado Electric has achieved a nearly 50% 
reduction in GHG emissions since 2005 and is on track to reach the State of Colorado’s 80% carbon reduction goal by 2030. Our 
goals are based on prudent and proven solutions to reduce our emissions while minimizing cost impacts to our customers. This 
keeps our customers at the forefront of our decision-making, which is central to our values.

More of our customers, particularly our larger customers, are demanding cleaner sources of energy to meet their sustainability 
goals. In addition, there is more interest from consumers, regulators and legislators to increase the use of renewable and other 
alternative energy sources. Recent efforts to support this interest include:

•

•

In June 2021, South Dakota Electric and Wyoming Electric submitted an IRP to the SDPUC and WPSC. The IRP 
outlines a range of options for the two electric utilities over a 20-year planning horizon to meet long-term forecasted 
energy needs while strengthening reliability and resiliency of the grid. The analysis focused on the least-cost 
resource needs to best meet customers’ future peak energy needs while maintaining system flexibility and achieving 
the Company’s generation emissions reduction goals. The IRP’s preferred options for South Dakota Electric in the 
near-term planning period through 2026 are the addition of 100 MW of renewable generation, the conversion of Neil 
Simpson II to dual fuel (natural gas and coal) in 2025 and consideration of up to 20 MW of battery storage. In 2023, 
South Dakota Electric issued a request for proposals for 100 MW of utility-owned renewable energy resources to be 
in service in 2026. Negotiations are underway, with results to be presented to the SDPUC and included in a CPCN 
filing with the WPSC during the first quarter of 2024.

In March 2023, the CPUC approved a unanimous settlement for Colorado Electric's Clean Energy Plan filed on May 
25, 2022. The Clean Energy Plan supports Colorado Electric's voluntary election to reduce carbon emissions 80% 
from 2005 levels by 2030. In July 2023, Colorado Electric issued a request for proposals for approximately 400 MW 
of new renewable resources to be in service by 2029 to achieve objectives in its Clean Energy Plan. Colorado 
Electric received a strong response to its request for proposal and provided a bids summary to the CPUC as part of 
the approval process. A report with Colorado Electric's recommended resources is due to the CPUC in the second 
quarter of 2024.

Many states have enacted, and others are considering, mandatory renewable energy standards, requiring utilities to meet certain 
thresholds of renewable energy generation. In addition, some states have either enacted or are considering legislation setting 
GHG emission reduction targets. Federal legislation for renewable energy standards and GHG emission reductions has been 
considered and may be implemented in the future. Mandates for the use of renewable energy or the reduction of GHG emissions 
will likely drive the need for significant investment in our Electric Utilities and Gas Utilities segments. These mandates will also 
likely increase prices for electricity and/or natural gas for our utility customers. As a regulated utility, we are responsible for 
providing safe, reliable and cost-effective sources of energy to our customers. Accordingly, we employ a customer-focused 
strategy for complying with standards and regulations that balances our customers’ rate concerns with environmental 
considerations and administrative and legislative mandates. We attempt to strike this balance by prudently and proactively 
incorporating renewable energy into our resource supply, while seeking to minimize the magnitude and frequency of rate 
increases for our utility customers.

Inflation Reduction Act

The IRA, signed into law by President Biden in August 2022, features $370 billion in spending and tax incentives on clean 
energy provisions. Most notably, the IRA includes provisions that extend and expand the production and investment tax credits 
for wind and solar; includes energy storage, EVs, RNG, and carbon capture and sequestration; and allows for the transferability 
of clean energy tax credits on existing and qualifying new facilities. We see the IRA as generally supportive of our Energy 
Transition strategy with the potential to drive increased value for our customers and shareholders. We are still evaluating the 
impacts of the IRA provisions on our future capital projects.

Deliver a competitive total return to investors and maintain an investment grade credit rating. We are proud of our track 
record of annual dividend increases for shareholders. 2023 represented our 53rd consecutive year of increasing dividends. In 
January 2024, our Board of Directors declared a quarterly dividend of $0.65 per share, equivalent to an annual dividend of $2.60 
per share. We intend to continue our record of annual dividend increases with a targeted dividend payout ratio of 55% to 65% of 
net income.

We require access to the capital markets to fund our planned capital investments or acquire strategic assets that support prudent 
and earnings-accretive business growth. We have demonstrated our ability to cost-effectively access the debt and equity 
markets, while maintaining our investment-grade issuer credit rating.

Macroeconomic Trends

Recent Developments

We continue to monitor challenging macroeconomic trends including supply chain disruptions, rising interest rates, potential 
recession and inflationary pressures on the prices of materials, outside services and employee costs. To date, we have 
experienced moderate net impacts from these trends. However, if current macroeconomic conditions deteriorate in 2024, 
adverse impacts to our businesses may be magnified.

Inflation has increased our operating expenses, which included higher employee-related expenses in 2023 compared to the prior 
year.

We are proactively managing increased costs of materials and supply chain disruptions to achieve our forecasted capital 
investment targets. To support our 2024 capital investment program, we have contracts in place with key suppliers and we have 
contracted services for a significant portion of our largest forecasted projects. We continue to forecast multi-year key material 
requirements with suppliers to enhance predictable material availability, challenge vendor price increases to ensure best value 
and cost transparency and invest in our distribution network to ensure the safety and reliability of our system. We have also 
evaluated each of our forecasted projects and will prioritize them depending on future constraints. Project delays may occur if 
costs rise significantly or if materials are not available.

Rising interest rates have led to increased interest expense on recent debt issuances. These impacts were partially offset by 
lower short-term, variable rate borrowings and higher interest income on our cash equivalents when compared to the prior year.

The deflationary trend in commodity prices throughout 2023 has partially offset macroeconomic headwinds from inflation and 
higher interest rates. Lower commodity prices have led to lower customer bills, lower cost of fuel, purchased power and natural 
gas sold, and improved cash flows from operations due to recoveries of deferred energy costs from customers (which were 
elevated at the end of 2022 and subsequently collected in 2023).

More detailed discussion of the future uncertainties can be found in Item 1A - Risk Factors.

The variance to the prior year included the following:

•

•

•

•

Electric Utilities’ operating income increased $34.5 million primarily due to new rates and rider recovery, a one-time 
gain on the planned sale of Northern Iowa Windpower assets, a gain on a strategic sale of land in Wyoming to a 
customer to support continued load growth, and a one-time recovery from our business interruption insurance 
related to the 2021 Wygen I unplanned outage partially offset by unfavorable weather, higher depreciation expense 
and higher employee-related expenses;
Gas Utilities’ operating income decreased $15.4 million primarily due to unfavorable weather, a prior year one-time 
true-up of carrying costs accrued on Winter Storm Uri regulatory assets and higher operating expenses partially 
offset by new rates and rider recovery and retail customer growth and demand;
Interest expense increased $6.9 million due to higher interest rates partially offset by increased interest income on 
higher cash and cash equivalents balances; and
Other expense, net increased $5.0 million primarily due to higher benefit plan non-service costs driven by higher 
discount rates and higher costs for our non-qualified deferred compensation plan driven by market performance.

Segment Operating Results

Non-GAAP Financial Measure

The following discussion includes financial information prepared in accordance with GAAP, as well as another financial measure, 
Electric and Gas Utility margin, that is considered a “non-GAAP financial measure.” Generally, a non-GAAP financial measure is 
a numerical measure of a company’s financial performance, financial position or cash flows that excludes (or includes) amounts 
that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with 
GAAP. Electric and Gas Utility margin (revenue less cost of sales) is a non-GAAP financial measure due to the exclusion of 
operation and maintenance expenses, depreciation and amortization expenses, and property and production taxes from the 
measure.

Electric Utility margin is calculated as operating revenue less cost of fuel and purchased power. Gas Utility margin is calculated 
as operating revenue less cost of natural gas sold. Our Electric and Gas Utility margin is impacted by the fluctuations in power 
and natural gas purchases and other fuel supply costs. However, while these fluctuating costs impact Electric and Gas Utility 
margin as a percentage of revenue, they only impact total Electric and Gas Utility margin if the costs cannot be passed through 
to our customers.

Our Electric and Gas Utility margin measure may not be comparable to other companies’ Electric and Gas Utility margin 
measures. Furthermore, this measure is not intended to replace operating income as determined in accordance with GAAP as 
an indicator of operating performance.

insurance which was recognized as Revenue. See Note 3 of the Notes to Consolidated Financial Statements in this Annual Report on 
Form 10-K for further information.
Primarily driven by favorable mining contract pricing and increased Black Hills Colorado IPP fired-engine hours.

Operations and maintenance expense decreased primarily due to a one-time $7.7 million gain on the planned sale of Northern 
Iowa Windpower assets, a $3.9 million gain on a strategic sale of land in Wyoming to a customer to support continued load 
growth, and $2.9 million of lower outside services expenses partially offset by $8.7 million of higher employee-related expenses.

Depreciation and amortization increased primarily due to higher asset base driven by prior and current year capital expenditures.

Taxes - property and production were comparable to the same period in the prior year.

In certain jurisdictions, we have commission approval to recover carrying costs on Winter Storm Uri regulatory assets which offset 
increased interest expense. Additionally, the carrying costs accrued during the year ended December 31, 2022 included a one-time, $10.3 
million true-up to reflect commission authorized rates.

Operations and maintenance expense increased primarily due to $14.8 million of higher employee-related expenses partially 
offset by $5.0 million of lower outside services expenses.

Depreciation and amortization was comparable to the prior year.

Taxes - property and production were comparable to the prior year.

Other (expense), net increased primarily due to higher benefit plan non-service costs driven by higher discount rates and higher 
costs for our non-qualified deferred compensation plan which were driven by market performance.

Income tax (expense) and the effective tax rate were comparable to the same period in the prior year. The effective tax rate was 
8.5% for both 2023 and 2022. The effective tax rate was comparable primarily due to a $8.2 million tax benefit from a current 
year Nebraska income tax rate decrease offset by $6.5 million of lower tax benefits from various current and prior year state tax 
rate changes and $3.6 million of lower wind PTCs resulting from the March 2023 sale of Northern Iowa Windpower assets. See 
Note 15 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K for additional details.

OVERVIEW

Liquidity and Capital Resources

Our company requires significant cash to support and grow our businesses. Our primary sources of cash are generated from our 
operating activities, Revolving Credit Facility, CP Program, ATM and ability to access the public and private capital markets 
through debt and equity securities offerings when necessary. This cash is used for, among other things, working capital, capital 
expenditures, dividends, pension funding, investments in or acquisitions of assets and businesses, payment of debt obligations 
and redemption of outstanding debt and equity securities when required or financially appropriate.

We experience significant cash requirements during peak months of the winter heating season due to higher natural gas 
consumption, during periods of high natural gas prices, and during the construction season, which typically peaks in spring and 
summer.

Net cash provided by operating activities was $359.6 million higher which was attributable to:

•

•

Total earnings (net income plus non-cash adjustments) were $23.0 million higher than prior year primarily as a result 
of increased Electric and Gas Utility margins due to new rates and increased rider revenues partially offset by higher 
operating expenses and higher interest expense.

Net inflows from changes in certain operating assets and liabilities were $349.4 million higher than prior year, 
primarily attributable to:



Cash inflows increased by approximately $515.8 million as a result of changes in accounts receivable and 
other current assets primarily due to higher collections on pass-through revenues and lower natural gas in 
storage inventories driven by fluctuations in commodity prices and timing of injections and withdrawals;

CAPITAL RESOURCES

Shelf Registration Statement

We maintain an effective shelf registration statement with the SEC under which we may issue, from time to time, an unspecified 
amount of senior debt securities, subordinate debt securities, common stock, preferred stock, warrants and other securities. See 
Note 8 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K for recent updates regarding our 
shelf registration statement.

Cash outflows increased $12.8 million from other operating activities primarily due to higher costs from cloud 

Short-term Debt

We have a $750 million Revolving Credit Facility that matures on July 19, 2026, with two one-year extension options (subject to 
consent from lenders). This facility includes an accordion feature that allows us to increase total commitments up to $1.0 billion 
with the consent of the administrative agent, the issuing agents and each bank increasing or providing a new commitment. We 
also have a $750 million, unsecured CP Program that is backstopped by the Revolving Credit Facility. Amounts outstanding 
under the Revolving Credit Facility and the CP Program, either individually or in the aggregate, cannot exceed $750 million.

The Revolving Credit Facility prohibits us from paying cash dividends if a default or an event of default exists prior to, or would 
result after, paying a dividend. Although these contractual restrictions exist, we do not anticipate triggering any default measures 
or restrictions.

The Revolving Credit Facility contains cross-default provisions that could result in a default under such agreements if BHC or its 
material subsidiaries failed to 1) make timely payments of debt obligations; or 2) triggered other default provisions under any 
debt agreement totaling, in the aggregate principal amount of $50 million or more that permit the acceleration of debt maturities 
or mandatory debt prepayment.

See Note 8 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K for more information on our 
Revolving Credit Facility and CP Program.

Cash inflows increased $18.4 million for other investing activities primarily due to proceeds from the sale of Northern 

Iowa Windpower assets and the strategic sale of land in Wyoming.

Utility Money Pool

As a utility holding company, we are required to establish a cash management program to address lending and borrowing 
activities between our utilities and the Company. We have established utility money pool agreements which address these 
requirements. These agreements are on file with the FERC and appropriate state regulators. Under the utility money pool 
agreements, our utilities may, at their option, borrow and extend short-term loans to the utility money pool at market-based rates. 
While the utility money pool may borrow funds from the Company (as ultimate parent company), the money pool arrangement 
does not allow loans from our utility subsidiaries to the Company (as ultimate parent company) or to non-regulated affiliates.

Long-term Debt

For information on our long-term debt, see Note 8 of the Notes to Consolidated Financial Statements in this Annual Report on 
Form 10-K.

Covenant Requirements

The Revolving Credit Facility and Wyoming Electric’s financing agreements contain covenant requirements. We were in 
compliance with these covenants as of December 31, 2023. See additional information in Note 8 of the Notes to Consolidated 
Financial Statements in this Annual Report on Form 10-K.

Equity

For information regarding equity, see Note 8 of the Notes to Consolidated Financial Statements in this Annual Report on Form 
10-K.

Cash outflows increased $651.0 million as a result of net repayment activity under our Revolving Credit 

Future Financing Plans

We will continue to assess debt and equity needs to support our capital investment plans and other strategic objectives. We plan 
to fund our capital plan and strategic objectives by using cash generated from operating activities and various financing 
alternatives, which could include our Revolving Credit Facility, our CP Program, debt offerings, the issuance of common stock 
under our ATM program or in an opportunistic block trade. We also plan to re-finance our $600 million, 1.0375%, senior 
unsecured notes due August 2024, at or before maturity date.

Financing for operational needs and capital expenditure requirements, not satisfied by operating cash flows, depends upon the 
cost and availability of external funds through both short and long-term financing. In order to operate and grow our business, we 
need to consistently maintain the ability to raise capital on favorable terms. Access to funds is dependent upon factors such as 
general economic and capital market conditions, regulatory authorizations and policies, the Company’s credit ratings, cash flows 
from routine operations and the credit ratings of counterparties. After assessing the current operating performance, liquidity and 
credit ratings of the Company, management believes that the Company will have access to the capital markets at prevailing 
market rates for companies with comparable credit ratings. We note that credit ratings are not recommendations to buy, sell, or 
hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be 
evaluated independently of any other rating.

CAPITAL REQUIREMENTS

Capital Expenditures

Capital expenditures are a substantial portion of our cash requirements each year and we continue to forecast a robust capital 
expenditure program during the next five years. See above in Key Elements of our Business Strategy for forecasted capital 
expenditure requirements. A significant portion of our capital expenditures are for safety, reliability and integrity of our system 
and is included in utility rate base and eligible for recovery from our utility customers with regulatory approval. Those capital 
expenditures also earn a rate of return authorized by the commissions in the jurisdictions in which we operate.

Our historical capital expenditures by reportable segment are shown in Note 16 of the Notes to Consolidated Financial 
Statements in this Annual Report on Form 10-K.

CREDIT RATINGS

Unconditional Purchase Obligations

We have unconditional purchase obligations which include the energy and capacity costs associated with our PPAs, 
transmission services agreements, and natural gas capacity, transportation and storage agreements. Additionally, our Gas 
Utilities have commitments to purchase physical quantities of natural gas under contracts indexed to various forward natural gas 
price curves. For additional information. see Note 3 of the Notes to Consolidated Financial Statements in this Annual Report on 
Form 10-K.

Defined Benefit Pension Plan

We have one defined benefit pension plan, the Black Hills Retirement Plan (Pension Plan). The unfunded status of the Pension 
Plan is defined as the amount the projected benefit obligation exceeds the plan assets. The unfunded status of the Pension Plan 
is $39.4 million as of December 31, 2023, compared to $35.2 million as of December 31, 2022. We do not have required 
contributions, however, we expect to make $2.3 million in contributions to our Pension Plan in 2024. See further information in 
Note 13 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

Common Stock Dividends

Future cash dividends, if any, will be dependent on our results of operations, financial position, cash flows, reinvestment 
opportunities and other factors, and will be evaluated and approved by our Board of Directors.

Additionally, there are certain statutory limitations that could affect future cash dividends paid. Federal law places limits on the 
ability of public utilities within a holding company structure to declare dividends. Specifically, under the Federal Power Act, a 
public utility may not pay dividends from any funds properly included in a capital account. The utility subsidiaries’ dividends may 
be limited directly or indirectly by state regulatory commissions or bond indenture covenants. See additional information in Note 
8 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

On January 26, 2024, our Board of Directors declared a quarterly dividend of $0.65 per share, equivalent to an annual dividend 
rate of $2.60 per share. The table below provides our dividends paid (in millions), dividend payout ratio and dividends paid per

Our three-year compound annualized dividend growth rate was 4.8%.

Collateral Requirements

Our Utilities maintain wholesale commodity contracts for the purchases and sales of electricity and natural gas which have 
performance assurance provisions that allow the counterparty to require collateral postings under certain conditions, including 
when requested on a reasonable basis due to a deterioration in our financial condition or nonperformance. A significant 
downgrade in our credit ratings, such as a downgrade to a level below investment grade, could result in counterparties requiring 
collateral postings under such adequate assurance provisions. The amount of credit support that we may be required to provide 
at any point in the future is dependent on the amount of the initial transaction, changes in the market price, open positions and 
the amounts owed by or to the counterparty. At December 31, 2023, we had sufficient liquidity to cover collateral that could be 
required to be posted under these contracts. The cash collateral we were required to post at December 31, 2023 was not 
material. See Note 9 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

Guarantees

We provide various guarantees, which represent off-balance sheet commitments, supporting certain of our subsidiaries under 
specified agreements or transactions. For more information on these guarantees, see Note 3 of the Notes to Consolidated 
Financial Statements in this Annual Report on Form 10-K.

Critical Accounting Estimates

We prepare our consolidated financial statements in conformity with GAAP. In many cases, the accounting treatment of a 
particular transaction is specifically dictated by GAAP and does not require management’s judgment in application. There are 
also areas which require management’s judgment in selecting among available GAAP alternatives. We are required to make 
certain estimates, judgments and assumptions that we believe are reasonable based upon the information available. We 
continue to closely monitor the macroeconomic environment and related impacts on our critical accounting estimates including, 
but not limited to, collectability of customer receivables, recoverability of regulatory assets, impairment risk of goodwill and long-
lived assets, and contingent liabilities. These estimates and assumptions affect the reported amounts of assets and liabilities at 
the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Actual 
results may differ from our estimates and to the extent there are material differences between these estimates, judgments or 
assumptions and actual results, our financial statements will be affected. We believe the following accounting estimates are the 
most critical in understanding and evaluating our reported financial results. We have reviewed these critical accounting estimates 
and related disclosures with our Audit Committee.

The following discussion of our critical accounting estimates should be read in conjunction with Note 1, “Business Description 
and Significant Accounting Policies” of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

Regulation

Our regulated Electric and Gas Utilities are subject to cost-of-service regulation and earnings oversight from federal and state 
utility commissions. This regulatory treatment does not provide any assurance as to achievement of desired earnings levels. Our 
retail electric and gas utility rates are regulated on a state-by-state basis by the relevant state regulatory commissions based on 
an analysis of our costs, as reviewed and approved in a regulatory proceeding. The rates that we are allowed to charge may or 
may not match our related costs and allowed return on invested capital at any given time.

Management continually assesses the probability of future recoveries associated with regulatory assets and future obligations 
associated with regulatory liabilities. Factors such as the current regulatory environment, recently issued rate orders and 
historical precedents are considered. As a result, we believe that the accounting prescribed under rate-based regulation remains 
appropriate and our regulatory assets are probable of recovery in current rates or in future rate proceedings.

To some degree, each of our Electric and Gas Utilities are permitted to recover certain costs (such as increased fuel and 
purchased power costs) outside of a base rate review. To the extent we are able to pass through such costs to our customers, 
and a state regulatory commission subsequently determines that such costs should not have been paid by the customers, we 
may be required to refund such costs.

As of December 31, 2023 and 2022, we had total regulatory assets of $480.1 million and $653.0 million, respectively, and total 
regulatory liabilities of $566.6 million and $518.6 million, respectively. See Note 2 of the Notes to Consolidated Financial 
Statements in this Annual Report on Form 10-K for further information.

Goodwill

We perform a goodwill impairment test on an annual basis or upon the occurrence of events or changes in circumstances that 
indicate that the asset might be impaired. Our annual goodwill impairment testing date is as of October 1, which aligns with our 
financial planning process.

Accounting standards for testing goodwill for impairment require the application of either a qualitative or quantitative assessment 
to analyze whether or not goodwill has been impaired. Goodwill is tested for impairment at the reporting unit level. Under either 
the qualitative or quantitative assessment, the estimated fair value of a reporting unit is compared with its carrying amount, 
including goodwill. If the carrying amount exceeds fair value, then an impairment loss would be recognized in an amount equal to 
that excess, limited to the amount of goodwill allocated to that reporting unit.

financial planning process.

We perform a goodwill impairment test on an annual basis or upon the occurrence of events or changes in circumstances that 

indicate that the asset might be impaired. Our annual goodwill impairment testing date is as of October 1, which aligns with our 

Accounting standards for testing goodwill for impairment require the application of either a qualitative or quantitative assessment 

to analyze whether or not goodwill has been impaired. Goodwill is tested for impairment at the reporting unit level. Under either 

the qualitative or quantitative assessment, the estimated fair value of a reporting unit is compared with its carrying amount, 

including goodwill. If the carrying amount exceeds fair value, then an impairment loss would be recognized in an amount equal to 

that excess, limited to the amount of goodwill allocated to that reporting unit.

Application of the goodwill impairment test requires judgment, including the identification of reporting units and determining the 
fair value of the reporting unit. We have determined that the reporting units for goodwill impairment testing are our operating 
segments, or components of an operating segment, that constitute a business for which discrete financial information is available 
and for which the CODM regularly reviews the operating results. We estimate the fair value of our reporting units using a 
combination of an income approach, which estimates fair value based on discounted future cash flows, and a market approach, 
which estimates fair value based on market comparables within the utility and energy industries.  These valuations require 
significant judgments, including, but not limited to: 1) estimates of future cash flows, based on our internal five-year business 
plans and adjusted as appropriate for our view of market participant assumptions, with long range cash flows estimated using a 
terminal value calculation; 2) estimates of long-term growth rates for our businesses; 3) the determination of an appropriate 
weighted-average cost of capital or discount rate; and 4) the utilization of market information such as recent sales transactions 
for comparable assets within the utility and energy industries. Varying by reporting unit, weighted average cost of capital in the 
range of 6.9% to 7.3% and long-term growth rate projections of 1.75% were utilized in the goodwill impairment test performed as 
of October 1, 2023. Although 1.75% was used for a long-term growth rate projection, the short-term projected growth rate is 
higher with planned recovery of capital investments through rider mechanisms and rate reviews. Under the market approach, we 
estimate fair value using multiples derived from comparable sales transactions and enterprise value to EBITDA for comparative 
peer companies for each respective reporting unit. These multiples are applied to operating data for each reporting unit to arrive 
at an indication of fair value. In addition, we add a reasonable control premium when calculating fair value utilizing the peer 
multiples, which is estimated as the premium that would be received in a sale in an orderly transaction between market 
participants.

The estimates and assumptions used in our impairment assessments are based on available market information and we believe 
they are reasonable. However, variations in any of the assumptions could result in materially different calculations of fair value 
and determinations of whether or not an impairment is indicated.

For the years ended December 31, 2023, 2022, and 2021, there were no impairment losses recorded. At December 31, 2023, 
the fair value exceeded the carrying value at all reporting units.

See Item 1A - Risk Factors and Note 1 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K 
for additional information.

Income Taxes

The Company and its subsidiaries file consolidated federal income tax returns. Each entity records income taxes as if it were a 
separate taxpayer for both federal and state income tax purposes and consolidating adjustments are allocated to the 
subsidiaries based on separate company computations of taxable income or loss.

The Company uses the asset and liability method in accounting for income taxes. Under the asset and liability method, deferred 
income taxes are recognized at currently enacted income tax rates, to reflect the tax effect of temporary differences between the 
financial and tax basis of assets and liabilities as well as operating loss and tax credit carryforwards. Such temporary differences 
are the result of provisions in the income tax law that either require or permit certain items to be reported on the income tax 
return in a different period than they are reported in the financial statements.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or 
all of the deferred tax assets will not be realized and provides any necessary valuation allowances as required. If we determine 
that we will be unable to realize all or part of our deferred tax assets in the future, an adjustment to the deferred tax asset would 
be made in the period such determination was made. These adjustments may increase or decrease earnings. Although we 
believe our assumptions, judgments and estimates are reasonable, changes in tax laws or our interpretations of tax laws and the 
resolution of current and any future tax audits could significantly impact the amounts provided for income taxes in our 
consolidated financial statements.
See Note 15 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K for additional information.

Our activities in the regulated and non-regulated energy industries expose us to a number of risks in the normal operations of 
our businesses. Depending on the activity, we are exposed to varying degrees of market risk and credit risk.

Market risk is the potential loss that may occur as a result of an adverse change in market price, rate or supply. We are exposed, 
but not limited to, the following market risks:

•

•

Commodity price risk associated with our retail natural gas services, wholesale electric power marketing activities and fuel 
procurement for several of our gas-fired generation assets. Market fluctuations may occur due to unpredictable factors 
such as the COVID-19 pandemic, weather (e.g. Winter Storm Uri), geopolitical events, market speculation, recession, 
inflation, pipeline constraints, and other factors that may impact natural gas and electric energy supply and demand; and

Interest rate risk associated with future debt, including reduced access to liquidity during periods of extreme capital 
markets volatility, such as the 2008 financial crisis and the COVID-19 pandemic.

Credit risk is associated with financial loss resulting from non-performance of contractual obligations by a counterparty.

To manage and mitigate these identified risks, we have adopted the Black Hills Corporation Risk Policies and Procedures. The 
Black Hills Corporation Risk Policies and Procedures have been approved by our Executive Risk Committee. These policies 
relate to numerous matters including governance, control infrastructure, authorized commodities and trading instruments, 
prohibited activities and employee conduct. We report any issues or concerns pertaining to the Risk Policies and Procedures to 
the Audit Committee of our Board of Directors. The Executive Risk Committee, which includes senior level executives, meets at 
least quarterly and as necessary, to review our business and credit activities and to ensure that these activities are conducted 
within the authorized policies.

Commodity Price Risk

Electric and Gas Utilities

Our utilities have various provisions that allow them to pass the prudently-incurred cost of energy through to the customer. To 
the extent energy prices are higher or lower than amounts in our current billing rates, adjustments are made on a periodic basis 
to reflect billed amounts to match the actual energy cost we incurred. In Colorado, South Dakota and Wyoming, we have ECA or 
PCA provisions that adjust electric rates when energy costs are higher or lower than the costs included in our tariffs. In 
Arkansas, Colorado, Iowa, Kansas, Nebraska and Wyoming, we have GCA provisions that adjust natural gas rates when our 
natural gas costs are higher or lower than the energy cost included in our tariffs. These adjustments are subject to periodic 
prudence reviews by the state regulatory commissions. If state regulatory commissions decide to discontinue these tariff-based 
adjustment mechanisms, or there are delays in the timing of recovery under these mechanisms, we may be more exposed to 
commodity price risk.

The operations of our utilities, including natural gas sold by our Gas Utilities and natural gas used by our Electric Utilities’ 
generation plants or those plants under PPAs where our Electric Utilities must provide the generation fuel (tolling agreements), 
expose our utility customers to natural gas price volatility. Therefore, as allowed or required by state regulatory commissions, we 
have entered into commission-approved hedging programs utilizing natural gas futures, options, over-the-counter swaps and 
basis swaps to reduce our customers’ underlying exposure to these fluctuations.

For our regulated Utilities’ hedging plans, unrealized and realized gains and losses, as well as option premiums and 
commissions on these transactions are recorded as Regulatory assets or Regulatory liabilities in the accompanying 
Consolidated Balance Sheets in accordance with the state utility commission guidelines. When the related costs are recovered 
through our rates, the hedging activity is recognized in the Consolidated Statements of Income. See additional information in 
Note 9 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

Wholesale Power

We periodically have wholesale power purchase and sale contracts used to manage purchased power costs and load 
requirements associated with serving our electric customers that are considered derivative instruments and do not qualify for the 
normal purchase and normal sales exception for derivative accounting. Changes in the fair value of these commodity derivatives 
are recognized in the Consolidated Statements of Income.

There is a potential risk that our wholesale power sales could exceed our current generating capacity, which may arise from 
unplanned plant outages or from unanticipated load demands. To manage such risk, we restrict wholesale off-system sales to 
amounts by which our anticipated generating capabilities and purchased power resources exceed our anticipated load 
requirements plus a required reserve margin.

The operations of our utilities, including natural gas sold by our Gas Utilities and natural gas used by our Electric Utilities’ 

generation plants or those plants under PPAs where our Electric Utilities must provide the generation fuel (tolling agreements), 

expose our utility customers to natural gas price volatility. Therefore, as allowed or required by state regulatory commissions, we 

have entered into commission-approved hedging programs utilizing natural gas futures, options, over-the-counter swaps and 

basis swaps to reduce our customers’ underlying exposure to these fluctuations.

For our regulated Utilities’ hedging plans, unrealized and realized gains and losses, as well as option premiums and 

commissions on these transactions are recorded as Regulatory assets or Regulatory liabilities in the accompanying 

Consolidated Balance Sheets in accordance with the state utility commission guidelines. When the related costs are recovered 

through our rates, the hedging activity is recognized in the Consolidated Statements of Income. See additional information in 

Note 9 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

Wholesale Power

We periodically have wholesale power purchase and sale contracts used to manage purchased power costs and load 

requirements associated with serving our electric customers that are considered derivative instruments and do not qualify for the 

normal purchase and normal sales exception for derivative accounting. Changes in the fair value of these commodity derivatives 

are recognized in the Consolidated Statements of Income.

There is a potential risk that our wholesale power sales could exceed our current generating capacity, which may arise from 

unplanned plant outages or from unanticipated load demands. To manage such risk, we restrict wholesale off-system sales to 

amounts by which our anticipated generating capabilities and purchased power resources exceed our anticipated load 

requirements plus a required reserve margin.

Black Hills Energy Services

To support our Choice Gas Program customers, we buy and sell natural gas at competitive prices by managing commodity price 
risk. As a result of these activities, this area of our business is exposed to risks associated with changes in the market price of 
natural gas. We manage our exposure to such risks using over-the-counter and exchange traded options and swaps with 
counterparties in anticipation of forecasted purchases and sales. A portion of our over-the-counter swaps have been designated 
as cash flow hedges to mitigate the commodity price risk associated with fixed price forward contracts to supply gas to our 
Choice Gas Program customers. The gain or loss on these designated derivatives is reported in AOCI in the accompanying 
Consolidated Balance Sheets and reclassified into earnings in the same period that the underlying hedged item is recognized in 
earnings.

At December 31, 2023 and 2022, a 10% change in market prices for our derivative instruments would not materially impact pre-
tax income, the fair values of our derivative assets and liabilities, or OCI.

See additional commodity risk and derivative information in Note 9 of the Notes to Consolidated Financial Statements in this 
Annual Report on Form 10-K.

Interest Rate Risk

Periodically, we have engaged in activities to manage risks associated with changes in interest rates. We have utilized pay-fixed 
interest rate swap agreements to reduce exposure to interest rate fluctuations associated with floating rate debt obligations and 
anticipated debt refinancings. At December 31, 2023, we had no interest rate swaps in place. Further details of past swap 
agreements are set forth in Note 9 of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

At December 31, 2023, over 99% of our debt is fixed rate debt, which limits our exposure to variable interest rate fluctuations. A 
hypothetical 100 basis point increase in the benchmark rate on our variable rate debt would have increased annual pretax 
interest expense by approximately $0.9 million and $4.1 million for the years ended December 31, 2023 and 2022, respectively.  
See Note 8 for further information on cash amounts outstanding under short- and long-term variable rate borrowings.

We are subject to interest rate risk associated with our pension and post-retirement benefit obligations. Changes in interest rates 
impact the liabilities associated with these benefit plans as well as the amount of income or expense recognized for these plans. 
Declines in the value of the plan assets could diminish the funded status of the pension plans and potentially increase the 
requirements to make cash contributions to these plans. See additional information in Note 13 of the Notes to Consolidated 
Financial Statements in this Annual Report on Form 10-K.

Credit Risk

We have adopted the Black Hills Corporation Credit Policy that establishes guidelines, controls and limits to manage and 
mitigate credit risk within risk tolerances established by the Board of Directors. We attempt to mitigate our credit exposure by 
conducting business primarily with high credit quality entities, setting tenor and credit limits commensurate with counterparty 
financial strength, obtaining master netting agreements and mitigating credit exposure with less creditworthy counterparties 
through parental guarantees, cash collateral requirements, letters of credit and other security agreements.

We perform periodic credit evaluations of our customers and adjust credit limits based upon payment history and the customer’s 
current creditworthiness, as determined by review of their current credit information. We maintain a provision for estimated credit 
losses based upon historical experience, changes in current market conditions, expected losses and any specific customer 
collection issue that is identified.

Management’s Report on Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-
15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Our internal control over financial reporting is a 
process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements for external purposes in accordance with generally accepted accounting principles.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined 
to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Because 
of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of 
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of 
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial 
Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2023, 
based on the criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission “COSO”. This evaluation included review of the documentation of controls, 
evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this 
evaluation. Based on our evaluation, we have concluded that our internal control over financial reporting was effective as of 
December 31, 2023.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Black Hills Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Black Hills Corporation and subsidiaries (the "Company") as 
of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, equity, and cash flows, 
for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the 
"financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the 
Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in 
the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of 
America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in 
Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission and our report dated February 14, 2024, expressed an unqualified opinion on the Company's internal control over 
financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included 
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included 
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall 
presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that 
was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that 
are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and 
we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the 
accounts or disclosures to which it relates.

Regulatory Accounting — Impact of Rate Regulation on the Financial Statements — Refer to Notes 1 and 2 to the 
Financial Statements.

Critical Audit Matter Description

The Company is subject to cost-of-service regulation and earnings oversight by state and federal utility commissions 
(collectively, the “Commissions”), which have jurisdiction over the Company’s electric rates in Colorado, Montana, South Dakota 
and Wyoming and natural gas rates in Arkansas, Colorado, Iowa, Kansas, Nebraska and Wyoming. Management has 
determined it meets the requirements under accounting principles generally accepted in the United States of America to prepare 
its financial statements applying the specialized rules to account for the effects of cost-based rate regulation. Accounting for the 
economics of rate regulation impacts multiple financial statement line items and disclosures, such as property, plant, and 
equipment; regulatory assets and liabilities; revenue; operating expenses; and income tax benefit (expense).

55

10-KFORM 10-K  |Rates are regulated on a state-by-state basis by the relevant state regulatory commissions based on an analysis of the 
Company's costs, as reviewed and approved in a regulatory proceeding. Rate regulation is premised on the full recovery of 
prudently incurred costs and a reasonable rate of return on invested capital. Decisions to be made by the Commissions in the 
future will impact the accounting for regulated operations, including decisions about the amount of allowable costs and return on 
invested capital included in rates and any refunds that may be required. While the Company has indicated its regulatory assets 
are probable of recovery in current rates or in future proceedings, there is a risk that the Commissions will not judge all costs to 
have been prudently incurred or that the rate regulation process in which rates are determined will not always result in rates that 
produce a full recovery of costs and the return on invested capital.

We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management to 
support its assertions about impacted account balances and disclosures and the high degree of subjectivity involved in 
assessing the impact of future regulatory orders on the financial statements. Management judgments include assessing the 
likelihood of (1) recovery in future rates of incurred costs, and (2) a refund or future rate reduction to be provided to customers. 
Given the uncertainty of future decisions by the Commissions, auditing these judgments required specialized knowledge of 
accounting for rate regulation and the rate setting process due to its inherent complexities.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:

•

•

•

•

•

We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future 
rates of costs incurred as property, plant, and equipment and deferred as regulatory assets, and (2) refunds or future 
reductions in rates that should be reported as regulatory liabilities. We tested the effectiveness of management’s controls 
over the initial recognition of amounts as property, plant, and equipment; regulatory assets or liabilities; and the monitoring 
and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates or of a future 
reduction in rates.

We read relevant regulatory orders issued by the Commissions, filings made by the Company, and other publicly available 
information, as appropriate, to assess the likelihood of recovery in future rates or of a future reduction in rates based on 
precedents of the Commissions’ treatment of similar costs under similar circumstances. We evaluated the external 
information and compared it to the Company’s recorded regulatory asset and liability balances for completeness and for 
any evidence that might contradict management’s assertions.

We obtained and evaluated an analysis from management regarding probability of recovery for regulatory assets or refund 
or future reduction in rates for regulatory liabilities not yet addressed in a regulatory order, as applicable, to assess 
management’s assertion that amounts are probable of recovery or of a future reduction in rates.

We inspected minutes of the board of directors to identify any evidence that may contradict management’s assertions 
regarding probability of recovery or refunds. We also inquired of management regarding current year rate filings and new 
regulatory assets or liabilities.

We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded and 
regulatory developments.

February 14, 2024

We have served as the Company's auditor since 2002.

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report 
on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over 
financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be 
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk 
that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our 
audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that 
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 
of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

(1) BUSINESS DESCRIPTION AND SIGNIFICANT ACCOUNTING POLICIES

Business Description

Black Hills Corporation is a customer-focused, growth-oriented utility company headquartered in Rapid City, South Dakota. We 
are a holding company that, through our subsidiaries, conducts our operations through the following reportable segments:  
Electric Utilities and Gas Utilities. Certain unallocated corporate expenses that support our operating segments are presented as 
Corporate and Other.

Use of Estimates and Basis of Presentation

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that 
affect the reported amounts of certain assets and liabilities and disclosure of contingent assets and liabilities at the date of the 
financial statements and the reported amounts of revenues and expenses during the reporting period. Changes in facts and 
circumstances or additional information may result in revised estimates and actual results could differ materially from those 
estimates.

Principles of Consolidation

The consolidated financial statements include the accounts of Black Hills Corporation and its wholly-owned and majority-owned 
and controlled subsidiaries. Furthermore, VIEs in which the Company has an ownership interest and is the primary beneficiary, 
thus controlling the VIE, have been consolidated. All intercompany balances and transactions have been eliminated in 
consolidation.

We use the proportionate consolidation method to account for our ownership interest in any jointly-owned facility. See Note 6 for 
additional information.

Non-controlling Interests

We account for changes in our controlling interests of subsidiaries according to ASC 810, Consolidation. ASC 810 requires that 
the Company record such changes as equity transactions, recording no gain or loss on such a sale. GAAP requires that non-
controlling interests in subsidiaries and affiliates be reported in the equity section of a company’s balance sheet. In addition, the 
amounts attributable to the non-controlling interest net income (loss) of those subsidiaries are reported separately in the 
consolidated statements of income and comprehensive income. See Note 12 for additional information.

Variable Interest Entities

We evaluate arrangements and contracts with other entities to determine if they are VIEs and if we are the primary beneficiary.  
GAAP provides a framework for identifying VIEs and determining when a company should include the assets, liabilities, non-
controlling interest and results of activities of a VIE in its consolidated financial statements.

A VIE should be consolidated if a party with an ownership, contractual or other financial interest in the VIE (a variable interest 
holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits 
of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary 
beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities and non-
controlling interests at fair value and subsequently account for the VIE as if it were consolidated.

Our evaluation of whether our interest qualifies as the primary beneficiary of a VIE involves significant judgments, estimates and 
assumptions and includes a qualitative analysis of the activities that most significantly impact the VIE’s economic performance 
and whether the Company has the power to direct those activities, the design of the entity, the rights of the parties and the 
purpose of the arrangement. Black Hills Colorado IPP is a VIE. See Note 12 for additional information.

Cash, Cash Equivalents and Restricted Cash

We consider all highly liquid investments with an original maturity of three months or less to be cash and cash equivalents. We 
maintain cash accounts for various specified purposes, which are classified as restricted cash.

Our revenue contracts generally provide for performance obligations that are fulfilled and transfer control to customers over time, 
represent a series of distinct services that are substantially the same, involve the same pattern of transfer to the customer and 
provide a right to consideration from our customers in an amount that corresponds directly with the value to the customer for the 
performance completed to date. Therefore, we recognize revenue in the amount to which we have a right to invoice. Our primary 
types of revenue contracts are:

•

•

Regulated natural gas and electric utility services tariffs - Our Utilities have regulated operations, as defined by ASC 
980, Regulated Operations, that provide services to regulated customers under tariff rates, charges, terms and 
conditions of service and prices determined by the jurisdictional regulators designated for our service territories. Our 
regulated services primarily encompass single performance obligations for delivery of either commodity natural gas, 
commodity electricity, natural gas transportation or electric transmission services. These service revenues are 
variable based on quantities delivered, influenced by seasonal business and weather patterns. Tariffs are only 
permitted to be changed through a rate-setting process involving the state or federal regulatory commissions to 
establish contractual rates between the utility and its customers. All of our Utilities’ regulated sales are subject to 
regulatory-approved tariffs.

Power sales agreements - Our Electric Utilities segment has long-term wholesale power sales agreements with 
other load-serving entities, including affiliates, for the sale of excess power from owned generating units. These 
agreements include a combination of “take or pay” arrangements, where the customer is obligated to pay for the 
energy regardless of whether it actually takes delivery, as well as “requirements only” arrangements, where the 
customer is only obligated to pay for the energy the customer needs. In addition to these long-term contracts, we 
also sell excess energy to other load-serving entities on a short-term basis. The pricing for all of these arrangements 
is included in the executed contracts or confirmations, reflecting the standalone selling price and is variable based 
on energy delivered. Certain energy sale and purchase transactions with the same counterparty and at the same 
delivery point are netted to reflect the economic substance of the arrangement.

The majority of our revenue contracts are based on variable quantities delivered. Any fixed consideration contracts with an 
expected duration of one year or more are immaterial to our consolidated revenues. Variable consideration constraints in the 
form of discounts, rebates, credits, price concessions, incentives, performance bonuses, penalties or other similar items are not 
material for our revenue contracts. We are the principal in our revenue contracts, as we have control over the services prior to 
those services being transferred to the customer.

Revenue Not in Scope of ASC 606

Other revenues included in the tables in Note 4 include our revenue accounted for under separate accounting guidance, 
including lease revenue under ASC 842, Leases, derivative revenue under ASC 815, Derivatives and Hedging, and alternative 
revenue programs revenue under ASC 980, Regulated Operations.

We evaluate arrangements and contracts with other entities to determine if they are VIEs and if we are the primary beneficiary.  

GAAP provides a framework for identifying VIEs and determining when a company should include the assets, liabilities, non-

controlling interest and results of activities of a VIE in its consolidated financial statements.

Significant Judgments and Estimates

Unbilled Revenue

A VIE should be consolidated if a party with an ownership, contractual or other financial interest in the VIE (a variable interest 

holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits 

of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary 

beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities and non-

controlling interests at fair value and subsequently account for the VIE as if it were consolidated.

Our evaluation of whether our interest qualifies as the primary beneficiary of a VIE involves significant judgments, estimates and 

assumptions and includes a qualitative analysis of the activities that most significantly impact the VIE’s economic performance 

and whether the Company has the power to direct those activities, the design of the entity, the rights of the parties and the 

purpose of the arrangement. Black Hills Colorado IPP is a VIE. See Note 12 for additional information.

To the extent that deliveries have occurred, but a bill has not been issued, our Utilities accrue an estimate of the revenue since 
the latest billing. This estimate is calculated based upon several factors including billings through the last billing cycle in a month 
and prices in effect in our jurisdictions. Each month, the estimated unbilled revenue amounts are trued-up and recorded in 
Accounts receivable, net on the accompanying Consolidated Balance Sheets.

Contract Balances

The nature of our primary revenue contracts provides an unconditional right to consideration upon service delivery; therefore, no 
customer contract assets or liabilities exist. The unconditional right to consideration is represented by the balance in our 
Accounts receivable, which is further discussed below.

Cash, Cash Equivalents and Restricted Cash

We consider all highly liquid investments with an original maturity of three months or less to be cash and cash equivalents. We 

maintain cash accounts for various specified purposes, which are classified as restricted cash.

See Note 4 for additional information.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are stated at billed and estimated unbilled amounts, net of allowance for credit losses, and do not bear 
interest. We maintain an allowance for credit losses which reflects our estimate of uncollectible trade receivables. We regularly 
review our trade receivable allowance by considering such factors as historical experience, credit worthiness, the age of the 
receivable balances and current economic conditions that may affect collectability.

properties that do not have legal retirement obligations are reclassified from accumulated depreciation and reflected as 

regulatory liabilities. Retirement or disposal of all other operating assets result in gains or losses recognized as a reduction to 

Operations and maintenance expense.

See Note 5 for additional information.

Depreciation

Depreciation provisions for property, plant and equipment are generally computed on a straight-line basis based on the 
applicable estimated service life of the various classes of property. The composite depreciation method is applied to regulated 
utility property. Depreciation studies are conducted periodically to update composite rates and are approved by state utility 
commissions and/or the FERC when required. Capitalized mining costs and coal leases are amortized on a unit-of-production 
method based on volumes produced and estimated reserves. For certain non-regulated power plant components, depreciation is 
computed on a unit-of-production methodology based on plant hours run.

AFUDC

Included in the cost of regulated construction projects is AFUDC, when applicable, which represents the approximate composite 
cost of borrowed funds and a return on equity used to finance a regulated utility project. The following table presents AFUDC

We also capitalize interest, when applicable, on undeveloped leasehold costs and certain non-regulated construction projects. In

increase to the carrying amounts of the related long-lived regulated utility assets in the period incurred. The amounts capitalized 
are included in Property, plant and equipment on the accompanying Consolidated Balance Sheets.

Asset Retirement Obligations

Accounting standards for AROs associated with long-lived assets require that the present value of retirement costs for which we 
have a legal obligation be recorded as liabilities with an equivalent amount added to the asset cost and depreciated over an 
appropriate period. The associated ARO accretion expense for our non-regulated operations, and regulated operations without a 
corresponding recovery mechanism, is included within Depreciation, depletion and amortization on the accompanying 
Consolidated Statements of Income. The accounting for the obligation for regulated operations with a regulatory mechanism has 
no income statement impact due to the deferral of the adjustments through the establishment of a regulatory asset or a 
regulatory liability.

We initially record liabilities for the present value of retirement costs for which we have a legal obligation, with an equivalent 
amount added to the asset cost. The asset is then depreciated or depleted over the appropriate useful life and the liability is 
accreted over time by applying an interest method of allocation. Any difference in the actual cost of the settlement of the liability 
and the recorded amount is recognized as a gain or loss in the results of operations at the time of settlement for our non-
regulated operations. See Note 7 for additional information.

Goodwill and Intangible Assets

Goodwill and intangible assets with indefinite lives are not amortized, but the carrying values are reviewed upon an indicator of 
impairment or at least annually. Intangible assets with a finite life are amortized over their estimated useful lives.

We perform a goodwill impairment test on an annual basis or upon the occurrence of events or changes in circumstances that 
indicate that the asset might be impaired. Our annual goodwill impairment testing date is as of October 1, which aligns our 
testing date with our financial planning process.

The Company has determined that the reporting units for its goodwill impairment test are its operating segments, or components 
of an operating segment.

Our goodwill impairment analysis includes an income approach and a market approach to estimate the fair value of our reporting 
units. These valuations require significant judgments, including, but not limited to: 1) estimates of future cash flows, based on our 
internal five-year business plans and adjusted as appropriate for our view of market participant assumptions, with long range 
cash flows estimated using a terminal value calculation; 2) estimates of long-term growth rates for our businesses; 3) the 
determination of an appropriate weighted-average cost of capital or discount rate; and 4) the utilization of market information 
such as recent sales transactions for comparable assets within the utility and energy industries.

We believe that goodwill reflects the inherent value of the relatively stable, long-lived cash flows of our Utilities businesses, 
considering the regulatory environment, and the long-lived cash flow and rate base growth opportunities at our Utilities, and 
those businesses vertically integrated. Goodwill amounts have not changed since 2016.

We use the following fair value hierarchy for determining inputs for our financial instruments. Our assets and liabilities for 
financial instruments are classified and disclosed in one of the following fair value categories:

Level 1 — Unadjusted quoted prices available in active markets that are accessible at the measurement date for identical 
unrestricted assets or liabilities. Level 1 instruments primarily consist of highly liquid and actively traded financial instruments 
with quoted pricing information on an ongoing basis.

Level 2 — Pricing inputs include quoted prices for identical or similar assets and liabilities in active markets other than quoted 
prices in Level 1, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted 
prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable 
market data by correlation or other means.

Level 3 — Pricing inputs are generally less observable from objective sources. These inputs reflect management’s best estimate 
of fair value using its own assumptions about the assumptions a market participant would use in pricing the asset or liability.

Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value 
measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may 
affect the placement within the fair value hierarchy levels. We record transfers, if necessary, between levels at the end of the 
reporting period for all of our financial instruments.

Transfers into Level 3, if any, occur when significant inputs used to value the derivative instruments become less observable, 
such as a significant decrease in the frequency and volume in which the instrument is traded, negatively impacting the 
availability of observable pricing inputs. Transfers out of Level 3, if any, occur when the significant inputs become more 
observable, such as when the time between the valuation date and the delivery date of a transaction becomes shorter, positively 
impacting the availability of observable pricing inputs.

Valuation Methodologies for Derivatives

The wholesale electric energy and natural gas commodity contracts for our Utilities are valued using the market approach and 
include forward strip pricing at liquid delivery points, exchange-traded futures, options, basis swaps and over-the-counter swaps 
and options (Level 2). For exchange-traded futures, options and basis swap assets and liabilities, fair value was derived using 
broker quotes validated by the exchange settlement pricing for the applicable contract. For over-the-counter instruments, the fair 
value is obtained by utilizing a nationally recognized service that obtains observable inputs to compute the fair value, which we 
validate by comparing our valuation with the counterparty. The fair value of these swaps includes a credit valuation adjustment 
based on the credit spreads of the counterparties when we are in an unrealized gain position or on our own credit spread when 
we are in an unrealized loss position.

See Notes 10 and 13 for additional information.

Derivatives and Hedging Activities

All our derivatives are measured at fair value and recognized as either assets or liabilities on the Consolidated Balance Sheets, 
except for derivative contracts that qualify for and are elected under the normal purchase and normal sales exception. Normal 
purchases and normal sales are contracts where physical delivery is probable, quantities are expected to be used or sold in the 
normal course of business over a reasonable amount of time and pricing is clearly and closely related to the asset being 
purchased or sold. Normal purchase and sales contracts are recognized when the underlying physical transaction is completed 
under the accrual basis of accounting.

In addition, certain derivative contracts approved by regulatory authorities are either recovered or refunded through customer 
rates. Any changes in the fair value of these approved derivative contracts are deferred as a regulatory asset or regulatory 
liability pursuant to ASC 980, Regulated Operations.

We also have some derivatives that qualify for hedge accounting and are designated as cash flow hedges. The gain or loss on 
these designated derivatives is deferred in AOCI and reclassified into earnings when the corresponding hedged transaction is 
recognized in earnings. Changes in the fair value of all other derivative contracts are recognized in earnings.

We utilize master netting agreements which consist of an agreement between two parties who have multiple contracts with each 
other that provide for the net settlement of all contracts in the event of default on or termination of any one contract. When the 
right of offset exists, accounting standards permit the netting of receivables and payables under a legally enforceable master 
netting agreement between counterparties. Accounting standards also permit offsetting of fair value amounts recognized for the 
right to reclaim, or the obligation to return, cash collateral against fair value amounts recognized for derivative instruments 
executed with the same counterparty. We reflect the offsetting of net derivative positions with fair value amounts for cash 
collateral with the same counterparty when a legal right of offset exists. Therefore, the gross amounts are not indicative of either 
our actual credit or net economic exposures.

The cash impacts of settled derivatives are recorded as operating activities on the Consolidated Statements of Cash Flows.

See Notes 9, 10 and 11 for additional information.

Debt Discounts, Premiums and Deferred Financing Costs

Deferred financing costs include loan origination fees, underwriter fees, legal fees and other costs directly attributable to the 
issuance of debt. Debt discounts, premiums and deferred financing costs are amortized over the estimated useful life of the 
related debt. Unamortized discounts, premiums and deferred financing costs are presented on the balance sheet as an 
adjustment to the related debt liabilities. See Note 8 for additional information.

Regulatory Accounting

Our regulated Utilities are subject to cost-of-service regulation and earnings oversight from federal and state regulatory 
commissions. Our Utilities account for income and expense items in accordance with accounting standards for regulated 
operations. These accounting policies differ in some respects from those used by our non-regulated businesses. Under these 
regulated operations accounting standards:

•

•

Certain costs, which would otherwise be charged to expense or OCI, are deferred as regulatory assets based on the 
expected ability to recover the costs in future rates.

Certain credits, which would otherwise be reflected as income or OCI, are deferred as regulatory liabilities based on 
the expectation the amounts will be returned to customers in future rates, or because the amounts were collected in 
rates prior to the costs being incurred.

69

10-KFORM 10-K  | 
 
 
Management continually assesses the probability of future recoveries and obligations associated with regulatory assets and 
liabilities. Factors such as the current regulatory environment, recently issued rate orders, and historical precedents are 
considered. As a result, we believe that the accounting prescribed under rate-based regulation remains appropriate and our 
regulatory assets are probable of recovery in current rates or in future rate proceedings.

If changes in the regulatory environment occur, we may no longer be eligible to apply this accounting treatment and may be 
required to eliminate regulatory assets and liabilities from our balance sheet. Such changes could adversely affect our results of 
operations, financial position or cash flows.

See Note 2 for additional information.

Income Taxes

The Company is subject to federal income tax as well as income tax in various state and local jurisdictions. The Company and its 
subsidiaries file consolidated federal income tax returns. Each subsidiary records both federal and state income taxes as if it 
were a separate taxpayer and consolidating expense adjustments are allocated to the subsidiaries based on separate company 
computations of taxable income or loss.

We use the asset and liability method in accounting for income taxes. Under the asset and liability method, deferred income 
taxes are recognized at currently enacted income tax rates, to reflect the tax effect of temporary differences between the 
financial and tax basis of assets and liabilities as well as operating loss and tax credit carryforwards. Such temporary differences 
are the result of provisions in the income tax law that either require or permit certain items to be reported on the income tax 
return in a different period than they are reported in the financial statements.

It is our policy to apply the flow-through method of accounting for ITCs. Under the flow-through method, ITCs are reflected in net 
income as a reduction to income tax expense in the year they qualify. An exception to this general policy is the deferral method, 
which applies to our regulated businesses. Such a method results in the ITC being amortized as a reduction to income tax 
expense over the estimated useful lives of the underlying property that gave rise to the credit.

We recognize interest income or interest expense and penalties related to income tax matters in Income tax expense on the 
Consolidated Statements of Income.

We have elected to account for transferable clean energy tax credits, including PTCs and ITCs within the provision for income 
taxes.

We account for uncertainty in income taxes recognized in the financial statements in accordance with the accounting standards 
for income taxes. The unrecognized tax benefit is classified in Other deferred credits and other liabilities or in Deferred income 
tax liabilities, net on the accompanying Consolidated Balance Sheets. See Note 15 for additional information.

Earnings per Share of Common Stock

Basic earnings per share is computed by dividing Net income available for common stock by the weighted average number of 
common shares outstanding during each year. Diluted earnings per share is computed by including all dilutive common shares 
outstanding during each year. Diluted common shares are primarily due to equity units, outstanding stock options, restricted 
stock and performance shares under our equity compensation plans.

A reconciliation of share amounts used to compute earnings per share is as follows for the years ended December 31 (in 
millions, except earnings per share amounts):

Net income available for common stock

Weighted average shares - basic
Dilutive effect of equity compensation
Weighted average shares - diluted

Share-Based Compensation

We account for our share-based compensation arrangements in accordance with ASC 718, Compensation-Stock Compensation, 
by recognizing compensation costs for all share-based awards over the respective service period for employee services received 
in exchange for an award of equity or equity-based compensation. Awards that will be settled in stock are accounted for as 
equity and the compensation expense is based on the grant date fair value. Awards that are settled in cash are accounted for as 
liabilities and the compensation expense is re-measured each period based on the current market price and performance 
achievement measures. See Note 14 for additional information.

Pension and Other Postretirement Plans

We recognize on our Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other 
postretirement plans with current-year changes in actuarial gains or losses recognized in AOCI, except for those plans at certain 
of our regulated utilities that can recover portions of their pension and postretirement obligations through future rates. All plan 
assets are recorded at fair value. We follow the measurement date provisions of ASC 715, Compensation-Retirement Benefits, 
which require a year-end measurement date of plan assets and obligations for all defined benefit plans.

We use the asset and liability method in accounting for income taxes. Under the asset and liability method, deferred income 

taxes are recognized at currently enacted income tax rates, to reflect the tax effect of temporary differences between the

the measure that is most consistent with GAAP, the disclosure of additional measures of segment profit or loss that are used by 
the CODM in assessing segment performance and deciding how to allocate resources. The ASU is effective for our Annual 
Report on Form 10-K for the fiscal year ended December 31, 2024, and subsequent interim periods, with early adoption 
permitted. We do not expect the ASU to have an impact on our financial position, results of operations and cash flows; however, 
are currently evaluating the impact on our consolidated financial statement disclosures.

taxes.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which expands public entities’ 
annual disclosures by requiring disclosure of tax rate reconciliation amounts and percentages for specific categories, income 
taxes paid disaggregated by federal and state taxes, and income tax expense disaggregated by federal and state taxes 
jurisdiction. The ASU is effective for our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, with early 
adoption permitted. We do not expect the ASU to have an impact on our financial position, results of operations and cash flows; 
however, are currently evaluating the impact on our consolidated financial statement disclosures.

We account for uncertainty in income taxes recognized in the financial statements in accordance with the accounting standards 

for income taxes. The unrecognized tax benefit is classified in Other deferred credits and other liabilities or in Deferred income 

tax liabilities, net on the accompanying Consolidated Balance Sheets. See Note 15 for additional information.

Earnings per Share of Common Stock

Basic earnings per share is computed by dividing Net income available for common stock by the weighted average number of 

common shares outstanding during each year. Diluted earnings per share is computed by including all dilutive common shares 

outstanding during each year. Diluted common shares are primarily due to equity units, outstanding stock options, restricted 

stock and performance shares under our equity compensation plans.

A reconciliation of share amounts used to compute earnings per share is as follows for the years ended December 31 (in 

millions, except earnings per share amounts):

Net income available for common stock

Weighted average shares - basic

Dilutive effect of equity compensation

Weighted average shares - diluted

In addition to recovery or repayment of costs, we are allowed a return on a portion of this amount or a reduction in rate base.

Regulatory assets represent items we expect to recover from customers through probable future rates.

Winter Storm Uri - Our Utilities have received commission approval to recover incremental fuel, purchased power and 
natural gas costs associated with Winter Storm Uri. In certain jurisdictions, we also received commission approval to 
recover carrying costs. As of December 31, 2023, we estimate that our remaining Winter Storm Uri regulatory asset has a 
weighted-average recovery period of 2.2 years.

Deferred Energy and Fuel Cost Adjustments - Deferred energy and fuel cost adjustments represent the cost of electricity 
delivered to our Electric Utilities’ customers that is either higher or lower than the current rates and will be recovered or 
refunded in future rates. Deferred energy and fuel cost adjustments are recorded and recovered or amortized as approved 
by the appropriate state regulatory commission. Our Electric Utilities file periodic quarterly, semi-annual and/or annual 
filings to recover these costs based on the respective cost mechanisms approved by their applicable state regulatory 
commissions.

Deferred Gas Cost Adjustments - Our regulated Gas Utilities have GCA provisions that allow them to pass the cost of gas 
on to their customers. The GCA is based on forecasts of the upcoming gas costs and recovery or refund of prior under-
recovered or over-recovered costs. To the extent that gas costs are under-recovered or over-recovered, they are recorded 
as a regulatory asset or liability, respectively. Our Gas Utilities file periodic monthly, quarterly, semi-annual and/or annual 
filings to recover these costs based on the respective cost mechanisms approved by their applicable state regulatory 
commissions.

Gas Price Derivatives - Our regulated Gas Utilities, as allowed or required by state regulatory commissions, have entered 
into certain exchange-traded natural gas futures and options to reduce our customers’ underlying exposure to fluctuations 
in gas prices. Gas price derivatives represent our unrealized positions on our commodity contracts supporting our utilities. 
Gas price derivatives at December 31, 2023 are hedged over a maximum forward term of two years.

Recovery/repayment of costs, but we are not allowed a rate of return.

In addition to recovery or repayment of costs, we are allowed a return on a portion of this amount or a reduction in rate base.

Regulatory assets represent items we expect to recover from customers through probable future rates.

Winter Storm Uri - Our Utilities have received commission approval to recover incremental fuel, purchased power and 

natural gas costs associated with Winter Storm Uri. In certain jurisdictions, we also received commission approval to 

recover carrying costs. As of December 31, 2023, we estimate that our remaining Winter Storm Uri regulatory asset has a 

weighted-average recovery period of 2.2 years.

refunded in future rates. Deferred energy and fuel cost adjustments are recorded and recovered or amortized as approved

on to their customers. The GCA is based on forecasts of the upcoming gas costs and recovery or refund of prior under-

recovered or over-recovered costs. To the extent that gas costs are under-recovered or over-recovered, they are recorded 

as a regulatory asset or liability, respectively. Our Gas Utilities file periodic monthly, quarterly, semi-annual and/or annual

Gas Price Derivatives - Our regulated Gas Utilities, as allowed or required by state regulatory commissions, have entered 

into certain exchange-traded natural gas futures and options to reduce our customers’ underlying exposure to fluctuations 

in gas prices. Gas price derivatives represent our unrealized positions on our commodity contracts supporting our utilities. 

Gas price derivatives at December 31, 2023 are hedged over a maximum forward term of two years.

Deferred Taxes on AFUDC - The equity component of AFUDC is considered a permanent difference for tax purposes with 
the tax benefit being flowed through to customers as prescribed or allowed by regulators. If, based on a regulator’s action, 
it is probable the utility will recover the future increase in taxes payable represented by this flow-through treatment through 
a rate revenue increase, a regulatory asset is recognized. This regulatory asset is a temporary difference for which a 
deferred tax liability must be recognized. Accounting standards for income taxes specifically address AFUDC-equity and 
require a gross-up of such amounts to reflect the revenue requirement associated with a rate-regulated environment.

Employee Benefit Plans and Related Deferred Taxes - Employee benefit plans include the unrecognized prior service 
costs and net actuarial loss associated with our defined benefit pension plan and post-retirement benefit plans in 
regulatory assets rather than in AOCI. In addition, this regulatory asset includes the income tax effect of the adjustment 
required under accounting for compensation - defined benefit plans, to record the full pension and post-retirement benefit 
obligations. Such income tax effect has been grossed-up to account for the revenue requirement associated with a rate 
regulated environment.

Environmental - Environmental costs associated with certain former manufactured gas plant sites. These costs are first 
offset by recognition of insurance proceeds and settlements with other third parties. Any remaining cost will be requested 
for recovery in future rate filings. Recovery for these specific environmental costs has not yet been approved by the 
applicable state regulatory commission and therefore, the recovery period is unknown at this time.

Loss on Reacquired Debt - Loss on reacquired debt is recovered over the remaining life of the original issue or, if 
refinanced, over the life of the new issue.

Deferred Taxes on Flow-Through Accounting - Under flow-through accounting, the income tax effects of certain tax items 
are reflected in our cost of service for the customer and result in lower utility rates in the year in which the tax benefits are 
realized. A regulatory asset was established to reflect that future increases in income taxes payable will be recovered from 
customers as the temporary differences reverse. As a result of this regulatory treatment, we continue to record a net tax 
benefit for costs considered currently deductible for tax purposes but are capitalized for book purposes.

Decommissioning Costs - South Dakota Electric and Colorado Electric received approval in 2014 for recovery of the 
remaining net book values and decommissioning costs of their decommissioned coal plants. In 2018, Arkansas Gas 
received approval to record Liquefied Natural Gas Plant decommissioning costs as a regulatory asset and received 
approval in 2020 to begin recovering those costs over three years.

Regulatory liabilities represent items we expect to refund to customers through probable future decreases in rates.

Deferred Energy and Gas Costs - Deferred energy and gas costs that have been over-recovered through customer rates 
and will be returned to customers in future periods.

Employee Benefit Plans and Related Deferred Taxes - Employee benefit plans represent the cumulative excess of 
pension and retiree healthcare costs recovered in rates over pension expense recorded in accordance with ASC 715, 
Compensation-Retirement Benefits. In addition, this regulatory liability includes the income tax effect of the adjustment 
required under ASC 715, Compensation-Retirement Benefits, to record the full pension and post-retirement benefit 
obligations. Such income tax effect has been grossed-up to account for the revenue requirement associated with a rate 
regulated environment.

Cost of Removal - Cost of removal represents the estimated cumulative net provisions for future removal costs for which 
there is no legal obligation for removal included in depreciation expense.

Excess Deferred Income Taxes - The revaluation of the regulated utilities' deferred tax assets and liabilities due to the 
passage of the TCJA was recorded as excess deferred income taxes to be refunded to customers primarily using the 
normalization principles as prescribed in the TCJA. A majority of the excess deferred taxes are subject to the average rate 
assumption method, as prescribed by the IRS, and will generally be amortized as a reduction of customer rates over the 
remaining lives of the related assets.

We are subject to costs resulting from a number of federal, state and local laws and regulations which affect future planning and 
existing operations. Laws and regulations can result in increased capital expenditures, operating and other costs as a result of 
compliance, remediation and monitoring obligations. Due to the environmental issues discussed below, we may be required to 
modify, curtail, replace or cease operating certain facilities or operations to comply with statutes, regulations and other 
requirements of regulatory bodies.

Reclamation Liability

For our Pueblo Airport Generation site, we posted a bond with the State of Colorado to cover the costs of remediation for a 
waste water containment pond permitted to provide wastewater storage and processing for this zero-discharge facility. The 
reclamation liability is recorded at the present value of the estimated future cost to reclaim the land.

Under our land leases for our wind generation facilities, we are required to reclaim land where we have placed wind turbines. 
The reclamation liabilities are recorded at the present value of the estimated future cost to reclaim the land.

Under its mining permit, WRDC is required to reclaim all land where it has mined reserves. The reclamation liability is recorded 
at the present value of the estimated future cost to reclaim the land.

See Note 7 for additional information.

Manufactured Gas Plant

In 2008, we acquired whole and partial liabilities for former manufactured gas plant sites in Nebraska and Iowa, which were 
previously used to convert coal to natural gas. The acquisition provided for an insurance recovery, now valued at $1.4 million 
recorded in Other assets, non-current on our Consolidated Balance Sheets, which will be used to help offset remediation costs. 
We also have a $2.7 million regulatory asset for manufactured gas plant sites; see Note 2 for additional information. As of 
December 31, 2023, we had $4.1 million and $0.6 million accrued for remediation of the manufactured gas plant sites in Iowa 
and Nebraska, respectively. Iowa's liabilities are included in Accrued Liabilities and Nebraska's liabilities are included in Other 
deferred credits and other liabilities on our Consolidated Balance Sheets. The remediation cost estimate could change materially 
due to results of further investigations, actions of environmental agencies or the financial viability of other responsible parties.

Contingencies and Legal Proceedings

In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted 
under laws and regulations. We believe the amounts provided in the consolidated financial statements to satisfy alleged liabilities 
are adequate in light of the probable and estimable contingencies. However, there can be no assurance that the actual amounts 
required to satisfy alleged liabilities from various legal proceedings, claims and other matters discussed, and to comply with 
applicable laws and regulations will not exceed the amounts reflected in the consolidated financial statements.

We record gain contingencies when realized and expected recoveries under applicable insurance contracts when we are 
assured of recovery.

GT Resources, LLC v. Black Hills Corporation, Case No. 2020CV30751 (U.S. District Court for the City and County of Denver, 
Colorado)

On April 13, 2022, a jury awarded $41 million for claims made by GT Resources, LLC (“GTR”) against BHC and two of its 
subsidiaries (Black Hills Exploration and Production, Inc. and Black Hills Gas Resources, Inc.), which ceased oil and natural gas 
operations in 2018 as part of BHC’s decision to exit the exploration and production business. The claims involved a dispute over 
a 2.3 million-acre concession award in Costa Rica which was acquired by a BHC subsidiary in 2003. GTR retained rights to 
receive a royalty interest on any hydrocarbon production from the concession upon the occurrence of contingent events. GTR 
contended that BHC and its subsidiaries failed to adequately pursue the opportunity and failed to transfer the concession to 
GTR. We appealed this verdict to the Colorado Court of Appeals. On October 19, 2023, the Appellate Court reversed and 
remanded the case with directions limiting any retrial to the narrow issue of whether there was improper interference with the 
prospective conveyance of the concession. We continue to believe this lawsuit has no merit and will vigorously defend it. At this 
time, we do not believe any losses from this matter will have a material impact on our financial position, results of operations and 
cash flows.

Gain Contingency -- Wygen 1 Business Interruption Insurance Recovery

In September 2021, Wygen I experienced an unplanned outage that continued until December 2021. For the year ended 
December 31, 2021, the outage resulted in lost revenues at our subsidiaries Black Hills Wyoming and WRDC. A claim for these 
losses was submitted under our business interruption insurance policy. During the third quarter of 2023 we recovered $5.0 
million from our business interruption insurance, which was recognized as Revenue in our Consolidated Statements of Income 
for year ended December 31, 2023.

Indemnification

In the normal course of business, we enter into agreements that include indemnification in favor of third parties, such as 
information technology agreements, purchase and sale agreements and lease contracts. We have also agreed to indemnify our 
directors, officers and employees in accordance with our articles of incorporation, as amended. Certain agreements do not 
contain any limits on our liability and therefore, it is not possible to estimate our potential liability under these indemnifications. In 
certain cases, we have recourse against third parties with respect to these indemnities. Further, we maintain insurance policies 
that may provide coverage against certain claims under these indemnities.

Guarantees

We have entered into various parent company-level guarantees providing financial or performance assurance to third parties on 
behalf of certain of our subsidiaries. These guarantees do not represent incremental consolidated obligations, but rather, 
represent guarantees of subsidiary obligations to allow those subsidiaries to conduct business without posting other forms of 
assurance. The agreements, which are off-balance sheet commitments, include support for business operations, indemnification 
for reclamation and surety bonds. The guarantees were entered into in the normal course of business. To the extent liabilities 
are incurred as a result of activities covered by these guarantees, such liabilities are included in our Consolidated Balance 
Sheets.

Contingencies and Legal Proceedings

In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted 

under laws and regulations. We believe the amounts provided in the consolidated financial statements to satisfy alleged liabilities 

are adequate in light of the probable and estimable contingencies. However, there can be no assurance that the actual amounts 

required to satisfy alleged liabilities from various legal proceedings, claims and other matters discussed, and to comply with 

applicable laws and regulations will not exceed the amounts reflected in the consolidated financial statements.

We record gain contingencies when realized and expected recoveries under applicable insurance contracts when we are 

assured of recovery.

Colorado)

GT Resources, LLC v. Black Hills Corporation, Case No. 2020CV30751 (U.S. District Court for the City and County of Denver, 

On April 13, 2022, a jury awarded $41 million for claims made by GT Resources, LLC (“GTR”) against BHC and two of its 

subsidiaries (Black Hills Exploration and Production, Inc. and Black Hills Gas Resources, Inc.), which ceased oil and natural gas 

operations in 2018 as part of BHC’s decision to exit the exploration and production business. The claims involved a dispute over 

a 2.3 million-acre concession award in Costa Rica which was acquired by a BHC subsidiary in 2003. GTR retained rights to 

receive a royalty interest on any hydrocarbon production from the concession upon the occurrence of contingent events. GTR 

contended that BHC and its subsidiaries failed to adequately pursue the opportunity and failed to transfer the concession to 

GTR. We appealed this verdict to the Colorado Court of Appeals. On October 19, 2023, the Appellate Court reversed and 

remanded the case with directions limiting any retrial to the narrow issue of whether there was improper interference with the 

prospective conveyance of the concession. We continue to believe this lawsuit has no merit and will vigorously defend it. At this 

time, we do not believe any losses from this matter will have a material impact on our financial position, results of operations and 

cash flows.

Gain Contingency -- Wygen 1 Business Interruption Insurance Recovery

In September 2021, Wygen I experienced an unplanned outage that continued until December 2021. For the year ended 

December 31, 2021, the outage resulted in lost revenues at our subsidiaries Black Hills Wyoming and WRDC. A claim for these 

losses was submitted under our business interruption insurance policy. During the third quarter of 2023 we recovered $5.0 

million from our business interruption insurance, which was recognized as Revenue in our Consolidated Statements of Income 

for year ended December 31, 2023.

Indemnification

In the normal course of business, we enter into agreements that include indemnification in favor of third parties, such as 

information technology agreements, purchase and sale agreements and lease contracts. We have also agreed to indemnify our 

directors, officers and employees in accordance with our articles of incorporation, as amended. Certain agreements do not 

contain any limits on our liability and therefore, it is not possible to estimate our potential liability under these indemnifications. In 

certain cases, we have recourse against third parties with respect to these indemnities. Further, we maintain insurance policies 

that may provide coverage against certain claims under these indemnities.

Guarantees

Sheets.

We have entered into various parent company-level guarantees providing financial or performance assurance to third parties on 

behalf of certain of our subsidiaries. These guarantees do not represent incremental consolidated obligations, but rather, 

represent guarantees of subsidiary obligations to allow those subsidiaries to conduct business without posting other forms of 

assurance. The agreements, which are off-balance sheet commitments, include support for business operations, indemnification 

for reclamation and surety bonds. The guarantees were entered into in the normal course of business. To the extent liabilities 

are incurred as a result of activities covered by these guarantees, such liabilities are included in our Consolidated Balance 

We had the following guarantees in place as of (in millions):

under a separate long-term agreement through December 31, 2026, with an annual renewal option for one-year extensions. This coal 
supply agreement is collateralized by a mortgage on and a security interest in some of WRDC’s coal reserves.
South Dakota Electric retains responsibility for plant operations. WRDC supplies fuel to Wygen III for the life of the plant.
Black Hills Wyoming retains responsibility for plant operations. WRDC supplies fuel to Wygen I for the life of the plant.

(7) ASSET RETIREMENT OBLIGATIONS

We have identified legal obligations related to reclamation of mining sites; removal of fuel tanks, transformers containing 
polychlorinated biphenyls, an evaporation pond; and reclamation of wind turbine sites at our Electric Utilities segment.  In 
addition, we have identified legal obligations related to retirement of gas pipelines, wells and compressor stations at our Gas 
Utilities and removal of asbestos at our Utilities. We periodically review and update estimated costs related to these AROs. The 
actual cost may vary from estimates due to regulatory requirements, changes in technology and increased labor, materials and 
equipment costs.

The following tables present the details of AROs which are included on the accompanying Consolidated Balance Sheets in Other 
deferred credits and other liabilities (in millions):

The Revisions to Prior Estimates were primarily driven by changes in estimates associated with natural gas wells and compressor 
stations.

We also have legally required AROs related to certain assets within our electric transmission and distribution systems. These 
retirement obligations are pursuant to an easement or franchise agreement and are only required if we discontinue our utility 
service under such easement or franchise agreement. Accordingly, it is not possible to estimate a time period when these 
obligations could be settled, and therefore, a liability for the cost of these obligations cannot be measured at this time.

Shelf Registration Statement

We maintain an effective shelf registration statement with the SEC under which we may issue, from time to time, an unspecified 
amount of senior debt securities, subordinate debt securities, common stock, preferred stock, warrants and other securities. In 
anticipation of the approaching expiration of our previous shelf registration statement on Form S-3 originally filed on August 4, 
2020 (Registration No. 333-240320), we filed a new shelf registration statement on Form S-3 on June 16, 2023 (Registration No.

Revolving Credit Facility and CP Program

On May 9, 2023, we amended and restated our corporate Revolving Credit Facility, which replaced LIBOR as a benchmark 
interest rate with the SOFR. The adoption of SOFR as a benchmark interest rate was in advance of the scheduled elimination of 
LIBOR as a benchmark interest rate on June 30, 2023. No other significant terms or conditions, including borrowing capacity, 
credit spreads or financial covenants were modified under these amendments and restatements.

We have a $750 million Revolving Credit Facility that matures on July 19, 2026, with two one-year extension options (subject to 
consent from lenders). This facility includes an accordion feature that allows us to increase total commitments up to $1.0 billion 
with the consent of the administrative agent, the issuing agents and each bank increasing or providing a new commitment. 
Borrowings continue to be available under a base rate or various SOFR rate options. The interest costs associated with the 
letters of credit or borrowings and the commitment fee under the Revolving Credit Facility are determined based upon our 
Corporate credit rating from S&P, Fitch and Moody's for our senior unsecured long-term debt. Based on our current credit 
ratings, the margins for base rate borrowings, SOFR borrowings and letters of credit were 0.125%, 1.125% and 1.125%, 
respectively, at December 31, 2023. Based on our credit ratings, the commitment fee on unused amounts was 0.175%.

We have a $750 million, unsecured CP Program that is backstopped by the Revolving Credit Facility. Amounts outstanding 
under the Revolving Credit Facility and the CP Program, either individually or in the aggregate, cannot exceed $750 million. The 
notes issued under the CP Program may have maturities not to exceed 397 days from the date of issuance and bear interest (or 
are sold at par less a discount representing an interest factor) based on, among other things, the size and maturity date of the 
note, the frequency of the issuance and our credit ratings. Under the CP Program, any borrowings rank equally with our 
unsecured debt. Notes under the CP Program are not registered and are offered and issued pursuant to a registration 
exemption.

Our Revolving Credit Facility and CP Program, which are classified as Notes payable on the Consolidated Balance Sheets, had 
the following borrowings, outstanding letters of credit, and available capacity at December 31 (dollars in millions):

Debt Transactions

On September 15, 2023, we completed a public debt offering of $450 million, 6.15% senior unsecured notes due May 15, 2034. 
Proceeds from the offering, which were net of $7.6 million of deferred financing costs, along with available cash were used to 
repay all of our $525 million principal amount outstanding notes on their November 30, 2023 maturity date and for other general 
corporate purposes.

On March 7, 2023, we completed a public debt offering of $350 million, 5.95% five year senior unsecured notes due March 15, 
2028. The proceeds from the offering, which were net of $4.2 million of deferred financing costs, were used to repay notes 
outstanding under our CP Program and for other general corporate purposes.

Revolving Credit Facility

We were in compliance with all of our Revolving Credit Facility covenants as of December 31, 2023. We are required to maintain 
a Consolidated Indebtedness to Capitalization Ratio not to exceed 0.65 to 1.00. Subject to applicable cure periods, a violation of 
this covenant would constitute an event of default that entitles the lenders to terminate their remaining commitments and 
accelerate all principal and interest outstanding. As of December 31, 2023, our Consolidated Indebtedness to Capitalization 
Ratio was 0.58 to 1.00.

Wyoming Electric

Wyoming Electric was in compliance with all covenants within its financing agreements as of December 31, 2023. Wyoming 
Electric is required to maintain a debt to capitalization ratio of no more than 0.60 to 1.00. As of December 31, 2023, Wyoming 
Electric's debt to capitalization ratio was 0.51 to 1.00.

Dividend Restrictions

Our Revolving Credit Facility and other debt obligations contain restrictions on the payment of cash dividends when a default or 
event of default occurs.

Due to our holding company structure, substantially all of our operating cash flows are provided by dividends paid or distributions 
made by our subsidiaries. The cash to pay dividends to our shareholders is derived from these cash flows. As a result, certain 
statutory limitations or regulatory or financing agreements could affect the levels of distributions allowed to be made by our 
subsidiaries.

Our Utilities are generally limited to the amount of dividends allowed to be paid to our utility holding company under the Federal 
Power Act and settlement agreements with state regulatory jurisdictions. As of December 31, 2023, the amount of restricted net 
assets at our Utilities that may not be distributed to our utility holding company in the form of a loan or dividend was 
approximately $142.6 million.

South Dakota Electric and Wyoming Electric are generally limited to the amount of dividends allowed to be paid to our utility

Market and Credit Risk Disclosures

Due to our holding company structure, substantially all of our operating cash flows are provided by dividends paid or distributions 

made by our subsidiaries. The cash to pay dividends to our shareholders is derived from these cash flows. As a result, certain 

statutory limitations or regulatory or financing agreements could affect the levels of distributions allowed to be made by our 

Our activities in the energy industry expose us to a number of risks in the normal operations of our businesses. Depending on 
the activity, we are exposed to varying degrees of market risk and credit risk.

Our Utilities are generally limited to the amount of dividends allowed to be paid to our utility holding company under the Federal 

Power Act and settlement agreements with state regulatory jurisdictions. As of December 31, 2023, the amount of restricted net 

assets at our Utilities that may not be distributed to our utility holding company in the form of a loan or dividend was 

approximately $142.6 million.

South Dakota Electric and Wyoming Electric are generally limited to the amount of dividends allowed to be paid to our utility 

holding company under certain financing agreements.

Although our aforementioned shelf registration statement does not limit our issuance capacity, our ability to issue securities is 

limited to the authority granted by our Board of Directors, certain covenants in our financing arrangements and restrictions 

imposed by federal and state regulatory authorities. Our articles of incorporation authorize the issuance of 100 million shares of 

common stock and 25 million shares of preferred stock. As of December 31, 2023, we had approximately 68 million shares of 

common stock outstanding and no shares of preferred stock outstanding.

Market Risk

Market risk is the potential loss that may occur as a result of an adverse change in market price, rate or supply. We are exposed, 
but not limited to, the following market risks:

Commodity price risk associated with our retail natural gas and wholesale electric power marketing activities and our 
fuel procurement for several of our gas-fired generation assets, which include market fluctuations due to 
unpredictable factors such as the COVID-19 pandemic, weather (e.g. Winter Storm Uri), geopolitical events, market 
speculation, recession, inflation, pipeline constraints, and other factors that may impact natural gas and electric 
supply and demand; and

Interest rate risk associated with future debt, including reduced access to liquidity during periods of extreme capital 
markets volatility, such as the 2008 financial crisis and the COVID-19 pandemic.

•

•

Credit Risk

Credit risk is the risk of financial loss resulting from non-performance of contractual obligations by a counterparty.

We attempt to mitigate our credit exposure by conducting business primarily with high credit quality entities, setting tenor and 
credit limits commensurate with counterparty financial strength, obtaining master netting agreements and mitigating credit 
exposure with less creditworthy counterparties through parental guarantees, cash collateral requirements, letters of credit and 
other security agreements.

We perform periodic credit evaluations of our customers and adjust credit limits based upon payment history and the customer’s 
current creditworthiness, as determined by review of their current credit information. We maintain a provision for estimated credit 
losses based upon historical experience, changes in current market conditions, expected losses and any specific customer 
collection issue that is identified. Our credit exposure at December 31, 2023 was concentrated primarily among retail utility 
customers, investment grade companies, cooperative utilities and federal agencies.

Derivatives and Hedging Activity

Our derivative and hedging activities included in the accompanying Consolidated Balance Sheets, Consolidated Statements of 
Income and Consolidated Statements of Comprehensive Income (Loss) are detailed below and within Note 10.

The operations of our Utilities, including natural gas sold by our Gas Utilities and natural gas used by our Electric Utilities’ 
generation plants or those plants under PPAs where our Electric Utilities must provide the generation fuel (tolling agreements), 
expose our utility customers to natural gas price volatility. Therefore, as allowed or required by state utility commissions, we 
have entered into commission approved hedging programs utilizing natural gas futures, options, over-the-counter swaps and 
basis swaps to reduce our customers’ underlying exposure to these fluctuations. These transactions are considered derivatives, 
and in accordance with accounting standards for derivatives and hedging, mark-to-market adjustments are recorded as 
Derivative assets or Derivative liabilities on the accompanying Consolidated Balance Sheets, net of balance sheet offsetting as 
permitted by GAAP.

For our regulated Utilities’ hedging plans, unrealized and realized gains and losses, as well as option premiums and 
commissions on these transactions are recorded as Regulatory assets or Regulatory liabilities in the accompanying 
Consolidated Balance Sheets in accordance with state regulatory commission guidelines. When the related costs are recovered 
through our rates, the hedging activity is recognized in the Consolidated Statements of Income.

We periodically have wholesale power purchase and sale contracts used to manage purchased power costs and load 
requirements associated with serving our electric customers that are considered derivative instruments due to not qualifying for 
the normal purchase and normal sales exception to derivative accounting. Changes in the fair value of these commodity 
derivatives are recognized in the Consolidated Statements of Income.

To support our Choice Gas Program customers, we buy, sell and deliver natural gas at competitive prices by managing 
commodity price risk. As a result of these activities, this area of our business is exposed to risks associated with changes in the 
market price of natural gas. We manage our exposure to such risks using over-the-counter and exchange traded options and 
swaps with counterparties in anticipation of forecasted purchases and sales during time frames ranging from January 2024 
through October 2025. A portion of our over-the-counter swaps have been designated as cash flow hedges to mitigate the 
commodity price risk associated with deliveries under fixed price forward contracts to deliver gas to our Choice Gas Program 
customers. The gain or loss on these designated derivatives is reported in AOCI in the accompanying Consolidated Balance 
Sheets and reclassified into earnings in the same period that the underlying hedged item is recognized in earnings. 
Effectiveness of our hedging position is evaluated at least quarterly.

The contract or notional amounts and terms of the natural gas derivative commodity instruments held by our utilities are 
comprised of both short and long positions. We had the following net long positions as of:

We have certain derivative contracts which contain credit provisions. These credit provisions may require the Company to post 
collateral when credit exposure to the Company is in excess of a negotiated line of unsecured credit. At December 31, 2023, the 
Company posted $2.0 million related to such provisions, which is included in Other current assets on the Consolidated Balance

As of December 31, 2023, $5.9 million of net losses related to our interest rate swaps and commodity derivatives are expected 
to be reclassified from AOCI into earnings within the next 12 months. As market prices fluctuate, estimated and actual realized 
gains or losses will change during future periods.

Derivatives Not Designated as Hedge Instruments

The following table summarizes the impacts of derivative instruments not designated as hedge instruments on our Consolidated 
Statements of Income for the years ended December 31, 2023, 2022 and 2021. Note that this presentation does not reflect the 
expected gains or losses arising from the underlying physical transactions; therefore, it is not indicative of the economic gross 
profit we realized when the underlying physical and financial transactions were settled.

As of December 31, 2023, 2,101,700 MMBtus of natural gas over-the-counter swaps purchased were designated as cash flow hedges.

Volumes exclude derivative contracts that qualify for the normal purchase, normal sales exception permitted by GAAP.

As discussed above, financial instruments used in our regulated Gas Utilities are not designated as cash flow hedges. However, 
there is no earnings impact because the unrealized gains and losses arising from the use of these financial instruments are 
recorded as Regulatory assets or Regulatory liabilities. The net unrealized losses included in a Regulatory asset related to these 
financial instruments used in our Gas Utilities were $5.1 million and $8.8 million at December 31, 2023 and 2022, respectively. 
For our Electric Utilities, the unrealized gains and losses arising from these derivatives are recognized in the Consolidated 
Statements of Income.

(12) VARIABLE INTEREST ENTITY

Black Hills Colorado IPP owns and operates a 200 MW, combined-cycle natural gas generating facility located in Pueblo, 
Colorado. In 2016, Black Hills Electric Generation sold a 49.9%, non-controlling interest in Black Hills Colorado IPP to a third-
party buyer. Black Hills Electric Generation is the operator of the facility, which is contracted to provide capacity and energy 
through 2031 to Colorado Electric.

Net income available for common stock for the years ended December 31, 2023, 2022 and 2021 was reduced by $13.8 million, 
$12.4 million, and $14.5 million, respectively, attributable to this non-controlling interest. The net income allocable to the non-
controlling interest holder is based on ownership interest with the exception of certain agreed upon adjustments. Distributions of 
net income attributable to this non-controlling interest are due within 30 days following the end of a quarter but may be withheld 
as necessary by Black Hills Electric Generation.

Black Hills Colorado IPP has been determined to be a VIE in which the Company has a variable interest. Black Hills Electric 
Generation has been determined to be the primary beneficiary of the VIE as Black Hills Electric Generation is the operator and 
manager of the generation facility and, as such, has the power to direct the activities that most significantly impact Black Hills 
Colorado IPP’s economic performance. Black Hills Electric Generation, as the primary beneficiary, continues to consolidate 
Black Hills Colorado IPP. Black Hills Colorado IPP has not received financial or other support from the Company outside of pre-
existing contractual arrangements during the reporting period. Black Hills Colorado IPP does not have any debt and its cash 
flows from operations are sufficient to support its ongoing operations.

We sponsor a 401(k) retirement savings plan (the 401(k) Plan). Participants in the 401(k) Plan may elect to invest a portion of 
their eligible compensation in the 401(k) Plan up to the maximum amounts established by the IRS. The 401(k) Plan provides 
employees the opportunity to invest up to 50% of their eligible compensation on a pre-tax or after-tax basis.

The 401(k) Plan provides a Company matching contribution for all eligible participants. Certain eligible participants who are not 
currently accruing a benefit in the Pension Plan also receive a Company retirement contribution based on the participant’s age 
and years of service. Vesting of all Company and matching contributions occurs at 20% per year with 100% vesting when the 
participant has 5 years of service with the Company.

Defined Benefit Pension Plan

We have one defined benefit pension plan, the Black Hills Retirement Plan (Pension Plan). The Pension Plan covers certain 
eligible employees of the Company. The benefits for the Pension Plan are based on years of service and calculations of average 
earnings during a specific time period prior to retirement. The Pension Plan is closed to new employees and frozen for certain 
employees who did not meet age and service-based criteria.

The Pension Plan assets are held in a Master Trust. Our Board of Directors has approved the Pension Plan’s investment policy.  
The objective of the investment policy is to manage assets in such a way that will allow the eventual settlement of our obligations 
to the Pension Plan’s beneficiaries. To meet this objective, our pension assets are managed by an outside adviser using a 
portfolio strategy that will provide liquidity to meet the Pension Plan’s benefit payment obligations. The Pension Plan’s assets 
consist primarily of equity, fixed income and hedged investments.

portfolio strategy that will provide liquidity to meet the Pension Plan’s benefit payment obligations. The Pension Plan’s assets 

consist primarily of equity, fixed income and hedged investments.

The expected rate of return on the Pension Plan assets is determined by reviewing the historical and expected returns of both 
equity and fixed income markets, taking into account asset allocation, the correlation between asset class returns and the mix of 
active and passive investments. The Pension Plan utilizes a dynamic asset allocation where the target range to return-seeking 
and liability-hedging assets is determined based on the funded status of the Plan. As of December 31, 2023, the expected rate 
of return on pension plan assets was based on the targeted asset allocation range of 20% to 28% return-seeking assets and 
72% to 80% liability-hedging assets.

Our Pension Plan is funded in compliance with the federal government’s funding requirements.

Supplemental Non-qualified Defined Benefit Plans

We have various supplemental retirement plans for key executives of the Company. The plans are non-qualified defined benefit 
and defined contribution plans (Supplemental Plans). The Supplemental Plans are subject to various vesting schedules and are 
funded on a cash basis as benefits are paid.

Non-pension Defined Benefit Postretirement Healthcare Plan

BHC sponsors a retiree healthcare plan (Healthcare Plan) for employees who meet certain age and service requirements at 
retirement. Healthcare Plan benefits are subject to premiums, deductibles, co-payment provisions and other limitations. A portion 
of the Healthcare Plan for participating business units are pre-funded via VEBA trusts. Pre-65 retirees as well as a grandfathered 
group of post-65 retirees receive their retiree medical benefits through the Black Hills self-insured retiree medical plans.

Healthcare coverage for post-65 Medicare-eligible retirees is provided through an individual market healthcare exchange. We 
fund the Healthcare Plan on a cash basis as benefits are paid. The Healthcare Plan provides for partial pre-funding via VEBA 
trusts. Assets related to this pre-funding are held in trust and are for the benefit of the union and non-union employees located in 
the states of Arkansas, Iowa and Kansas. We do not pre-fund the Healthcare Plan for those employees outside Arkansas, Iowa 
and Kansas.

Plan Contributions

Contributions to the Pension Plan are cash contributions made directly to the Master Trust. Healthcare and Supplemental Plan 
contributions are made in the form of benefit payments. Healthcare benefits include company and participant paid premiums.

Contributions for the years ended December 31 were as follows (in millions):

Common Collective Trust Funds: These funds are valued based upon the redemption price of units held by the Pension Plan, 
which is based on the current fair value of the common collective trust funds’ underlying assets. Unit values are determined by 
the financial institution sponsoring such funds by dividing the fund’s net assets at fair value by its units outstanding at the 
valuation dates. The Pension Plan’s investments in common collective trust funds, with the exception of shares of the common 
collective trust-real estate are categorized as Level 2.

Pension Plan

Common Collective Trust Funds: These funds are valued based upon the redemption price of units held by the Pension Plan, 

which is based on the current fair value of the common collective trust funds’ underlying assets. Unit values are determined by 

the financial institution sponsoring such funds by dividing the fund’s net assets at fair value by its units outstanding at the 

valuation dates. The Pension Plan’s investments in common collective trust funds, with the exception of shares of the common 

collective trust-real estate are categorized as Level 2.

The following investments are measured at NAV and are not classified in the fair value hierarchy, in accordance with accounting 
guidance:

Common Collective Trust-Real Estate Funds: These funds are valued based on various factors of the underlying real estate 
properties, including market rent, market rent growth, occupancy levels, etc. As part of the trustee’s valuation process, 
properties are externally appraised generally on an annual basis. The appraisals are conducted by reputable independent 
appraisal firms and signed by appraisers that are members of the Appraisal Institute, with professional designation of 
Member, Appraisal Institute. All external appraisals are performed in accordance with the Uniform Standards of Professional 
Appraisal Practices.  We receive monthly statements from the trustee, along with the annual schedule of investments and 
rely on these reports for pricing the units of the fund.

Hedge Funds: These funds represent investments in other investment funds that seek a return utilizing a number of diverse 
investment strategies. The strategies, when combined, aim to reduce volatility and risk while attempting to deliver positive 
returns under all market conditions. Amounts are reported on a one-month lag. The fair value of hedge funds is determined 
using net asset value per share based on the fair value of the hedge fund’s underlying investments. 10% of the shares may 
be redeemed at the end of each month with a 15-day notice and full redemptions are available at the end of each quarter 
with 60-day notice and is limited to a percentage of the total net assets value of the fund. The net asset values are based on 
the fair value of each fund’s underlying investments. There are no unfunded commitments related to these hedge funds.

government money market fund. As shares held reflect quoted prices in an active market, they are categorized as Level 1.

Service costs are recorded in Operations and maintenance expense while non-service costs are recorded in Other expense on 
the Consolidated Statements of Income.

Actuarial gains and losses are amortized using a straight-line method over the average remaining service period of active plan 
participants or over the average remaining lifetime of the remaining plan participants if the plan is viewed as “all or almost all” 
inactive participants.

strategies including lump sum buyouts, the purchase of annuities and the reduction of return-seeking assets over time to a more 
liability-hedged portfolio. As a result, capital markets volatility had a limited impact to our unfunded status.

Our Amended and Restated 2015 Omnibus Incentive Plan allows for the granting of stock, restricted stock, restricted stock units, 
stock options, performance shares and performance share units. We had 2,132,275 shares available to grant at December 31, 
2023.

Compensation expense is determined using the grant date fair value estimated in accordance with the provisions of accounting 
standards for stock compensation and is recognized over the vesting periods of the individual awards. As of December 31, 2023, 
total unrecognized compensation expense related to non-vested stock awards was $10.6 million and is expected to be 
recognized over a weighted-average period of 1.7 years. Stock-based compensation expense, which is included in Operations 
and maintenance on the accompanying Consolidated Statements of Income, was as follows for the years ended December 31

Performance Share Units

Beginning in 2021, certain officers of the Company, and its subsidiaries, were granted performance share units which have a 
three-year vesting period, do not have voting rights until vested, and are subject to three specified conditions. A market condition 
of relative total shareholder return and two equally weighted performance metrics of average earnings per share and the 
average cost to serve. Beginning in 2023, the metric of natural gas emissions reduction by 2035 was added, resulting in three 
equally weighted performance metrics. The units are paid 100% in common stock should conditions be met and can range from 
0% to 200% of the target award. Dividend equivalents are accrued during the vesting period and paid out based on the final 
number of shares awarded. In the event of participant’s death or retirement at age 55 or older, shares awarded vest on a pro-
rata basis commensurate with the months of service performed over the three-year period.

Performance Share Units - Market Condition

The fair value of each share unit is based on the Company’s closing price at December 31 of the year prior to the award and a 
Monte Carlo simulation. The Monte Carlo simulation is used to estimate expected share payout based on the Company’s TSR 
for a three-year performance period relative to the designated peer group beginning January 1 of the award year. The significant 
assumptions included in the company's Monte Carlo simulations were as follows:

Fair value of share units award

Black Hills Corporation’s common stock volatility
Volatility range for the peer group

A performance condition share unit vests at the end of the three-year performance period if the specified performance conditions 
are achieved. The conditions are based on the Company’s average earnings per share, the average cost to serve and natural 
gas emissions reductions by 2035. The grant-date fair value for an individual outcome of a performance condition is determined 
by the closing common share price on the grant date or, beginning in 2023, the average ten-day closing common share price 
preceding the grant date.

Prior to 2021, certain officers of the Company and its subsidiaries became participants in a market-based performance share 
award plan. Performance shares are awarded based on our total shareholder return over designated performance periods as 
measured against a selected peer group. In addition, certain stock price performance must be achieved for a payout to occur. 
The final value of the performance shares will vary according to the number of shares of common stock that are ultimately 
granted based upon the actual level of attainment of the performance criteria.

As of December 31, 2023, there was $6.3 million of unrecognized compensation expense related to non-vested restricted stock 

These performance share awards were paid 50% in cash and 50% in common stock.

The outstanding performance periods at December 31, 2023 were as follows:

As of December 31, 2023, there was $4.0 million of unrecognized compensation expense related to outstanding performance 
share/units that is expected to be recognized over a weighted-average period of 1.8 years.

On January 25, 2024, the Compensation Committee of our Board of Directors confirmed a payout equal to 16.21% of target 
shares valued at $0.5 million. The payout was fully accrued at December 31, 2023.

The grant date fair values for the performance shares granted in 2020 were determined by Monte Carlo simulation using a blended 
volatility of 18%, comprised of 50% historical volatility and 50% implied volatility and the average risk-free interest rate of the three-year 
United States Treasury security rate in effect as of the grant date.

Performance plan payouts have been as follows (in millions, except stock issued):

Beginning in 2021, certain officers of the Company, and its subsidiaries, were granted performance share units which have a 

three-year vesting period, do not have voting rights until vested, and are subject to three specified conditions. A market condition

A performance condition share unit vests at the end of the three-year performance period if the specified performance conditions 

are achieved. The conditions are based on the Company’s average earnings per share, the average cost to serve and natural 

gas emissions reductions by 2035. The grant-date fair value for an individual outcome of a performance condition is determined 

by the closing common share price on the grant date or, beginning in 2023, the average ten-day closing common share price 

preceding the grant date.

IRS Revenue Procedure 2023-15

On April 14, 2023, the IRS released Revenue Procedure 2023-15 “Amounts paid to improve tangible property.” The Revenue 
Procedure provides a safe harbor method of accounting that taxpayers may use to determine whether costs to repair, maintain, 
replace, or improve natural gas transmission and distribution property must be capitalized. The revenue procedure may be 
adopted in tax years ending after May 1, 2023. We are currently assessing the Revenue Procedure to determine its impact on 
our tax repairs deduction.

The state effective tax rate contains the tax expense attributable to multiple statutory state rate changes in the Company's state 
jurisdictions. For the year ended December 31, 2023, we recognized an $8.2 million tax benefit from a Nebraska income tax rate 
decrease.
The effective tax rate reflects the income attributable to the non-controlling interest in Black Hills Colorado IPP for which a tax provision 
was not recorded.
Flow-through adjustments related primarily to accounting method changes for tax purposes that allow us to take a current tax deduction 
for repair costs and certain indirect costs. We recorded a deferred income tax liability in recognition of the temporary difference created 
between book and tax treatment and flowed the tax benefit through to tax expense. A regulatory asset was established to reflect the 
recovery of future increases in taxes payable from customers as the temporary differences reverse. As a result of this regulatory 
treatment, we continue to record tax benefits consistent with the flow-through method.
Primarily TCJA - see Note 2 for additional information.
Primarily related to one-time bill credits of TCJA benefits delivered to Colorado Electric and Nebraska Gas customers in 2021. These bill 
credits, which resulted in a reduction in revenue, were offset by a reduction in income tax expense and resulted in a minimal impact to Net 
income for the year ended December 31, 2021.

The carryforward balance is reflected on the basis of apportioned tax losses to jurisdictions imposing state income taxes.

As of December 31, 2023, we had a $1.0 million valuation allowance against the state NOL carryforwards. Our 2023 analysis of 
the ability to utilize such NOLs resulted in no increase in the valuation allowance. If the valuation allowance is adjusted due to 
higher or lower than anticipated utilization of the NOLs, the offsetting amount will affect tax expense.

As of December 31, 2023, we had a $14.4 million valuation allowance against the state ITC carryforwards. Our 2023 analysis of 
the ability to utilize such ITC resulted in a slight decrease in the valuation allowance.

Unrecognized Tax Benefits

(16) BUSINESS SEGMENT INFORMATION

Our Chief Executive Officer, who is considered to be our CODM, reviews financial information presented on an operating 
segment basis for purposes of making decisions, allocating resources and assessing financial performance. Our operating 
segments are based on our method of internal reporting, which is generally segregated by differences in products and services. 
All of our operations and assets are located within the United States.

Our Electric Utilities segment includes the operating results of the regulated electric utility operations of Colorado Electric, South 
Dakota Electric, and Wyoming Electric, which supply regulated electric utility services to areas in Colorado, Montana, South 
Dakota and Wyoming. We also own and operate non-regulated power generation and mining businesses that are vertically 
integrated with our Electric Utilities.

Our Gas Utilities segment consists of the operating results of our regulated natural gas utility subsidiaries in Arkansas, Colorado, 
Iowa, Kansas, Nebraska and Wyoming.

Corporate and Other represents certain unallocated expenses for administrative activities that support our operating segments. 
Corporate and Other also includes business development activities that are not part of our operating segments and inter-
segment eliminations.

Our CODM assesses the performance of our operating segments based on operating income. Our CODM reviews capital 
expenditures by operating segment rather than any individual or total asset amount. Our operating segments are equivalent to 
our reportable segments.
