ANNUAL REPORT 2018Destination2050

Our bold  
carbon-free  
FUTURE

Xcel Energy has long been a leader in 
delivering clean energy while maintaining 
outstanding reliability and affordability.  
Back in 2005, we were the leading utility 
wind energy provider in the country, despite 
the fact that wind comprised only 3 percent 
of our generation. By 2027, we expect 
renewable energy — the vast majority being 
wind — will account for 48 percent of our 
mix and will be our largest source of energy  
for our customers.

Along the way, we’ve made steady progress 
reducing carbon dioxide by transitioning 
away from fossil fuels, incorporating 
renewables and developing award-winning 
energy efficiency programs. Our 2018 carbon 
emissions are approximately 40 percent 
lower than our 2005 baseline. That progress 
put us on pace to hit our previous goal of 
reducing carbon 60 percent across all eight 
states in which we do business by 2030.

the risk of climate change — convinced us 
that we can do more, sooner. That’s  
why in December, we became the first 
electric utility in the country to announce  
our aspiration to produce 100-percent 
carbon-free electricity for customers by 
2050. At the same time, we announced 
a new interim target of reducing carbon 
dioxide emissions 80 percent by 2030.

Significant advances in technology and  
our ability to integrate high levels of 
renewable energy onto our system give  
us the confidence that we expect to hit our  
80 percent target by 2030 using existing 
technologies. To produce 100-percent 
carbon-free electricity for customers 
by 2050 will require a dispatchable 
carbon-free energy source that is not 
available today. Of course, reliability and 
affordability must be part of the equation 
to successfully arrive at our destination.

Setting our sights on this ambitious vision 
— Destination 2050 — allows us to drive 
the conversation rather than react to it. It 
also gives us time for the development of 
technologies not currently available that  
will be critical for achieving 100-percent 
carbon-free electricity. And as important, 
it gives us a long runway to work with our 
local communities and employees to help 
prepare for a clean energy economy.

But a confluence of market forces — 
improving technology, falling prices and  

We’re excited to make advances toward 
Destination 2050 and can’t wait to build the 
future together.

Dear Fellow 
Shareholders:

Destination2050ANNUAL REPORT 20182018 was a year of significant accomplishments for our company.  While we achieved outstanding financial performance, marked major milestones in our Steel for Fuel strategy, and partnered with other utilities to restore power in Puerto Rico following Hurricane Maria, it was our announcement that we see a path to achieve 100-percent carbon-free energy by 2050 that took the spotlight.Xcel Energy has long been a leader in clean, renewable energy, but we took that to a  new level when we became the first major U.S. electric company to announce a  carbon-free vision — to serve customers with zero-carbon electricity by 2050. “Destination 2050: Building the Future” captures our long-range vision. But our vision to deliver 100-percent carbon-free energy by 2050 is more than just words. I like to think that we are not just talking about the future, we’re building it today. Outstanding Financial PerformanceFor the 14th consecutive year, we met or exceeded our earnings guidance. We delivered 2018 GAAP and ongoing earnings of $2.47 per share, at the top end of our original earnings guidance range, compared to GAAP earnings of $2.25 per share and ongoing earnings of $2.30 per share in 2017. Xcel Energy also increased your dividend 5.6 percent in 2018, extending our streak of dividend growth to 15 consecutive years.  We maintained our dividend objective of 5 to 7 percent annual growth, which reflects our confidence in our long-term financial plan. Strong earnings were driven in part by positive sales growth, particularly to support oil and gas production in Texas and New Mexico. Electric sales increased 1.3 percent and natural gas sales increased 2.4 percent, indicating strong customer growth despite continued advances in energy efficiency.Because our financial results were so strong during the first two quarters, we made the strategic decision to reinvest earnings into our business for system maintenance and vegetation management. This was a factor in our 3.6 percent increase in operating and maintenance (O&M) expenses in 2018. We remain committed to our long-term objective of improving operating efficiencies and eliminating costs to deliver greater value  to our customers and shareholders. As a result of our continued strong performance, our total shareholder return has outpaced our peer group. Our three-year total shareholder return was 51.1 percent compared to 34.6 percent for our peer group, and our five-year return was 109.5 percent compared to 65.9 percent for our peer group. In addition, our stock price (ticker: XEL) closed at an all-time high of $53.68 in December, and has subsequently set several new all-time highs in early 2019.Building the Future TodayWe continue to make strong progress in executing our Steel for Fuel growth strategy and are well-positioned to lead the clean energy transition and deliver strong shareholder value for years to come. Developing and owning wind farms brings our customers low-cost, carbon-free wind energy, while it creates economic development for communities and new investments for shareholders. It is a win-with-wind strategy that appeals to multiple stakeholders. Our Steel for Fuel wind strategy is visible  on the eastern plains of Colorado, where  the largest wind farm we’ve ever built — XCEL ENERGY EARNINGS

ANNUAL REPORT 2018the 600-megawatt Rush Creek Wind Farm — began producing enough carbon-free energy to power 325,000 homes. We are in the midst of one of the largest multi-state wind expansions in the country. With the completion of Rush Creek in Colorado, we have 11 remaining wind farms under development. In 2018, we secured the last of the necessary approvals for the projects, eight of which we will own. Five wind farms will be completed this year, with five expected to come online in 2020. The Dakota Range Wind Farm in South Dakota is set to begin service in 2021 after the production tax credit begins to phase down.But, we aren’t stopping there. We need to make progress every day to meet our vision of providing carbon-free electricity for customers by 2050 and reducing carbon emissions 80 percent system wide by 2030 (compared to 2005 levels). At the end of 2018, we had reduced carbon emissions  by approximately 40 percent.Our carbon footprint will continue to  shrink following the approval of our Colorado Energy Plan, which includes  the early retirement of two coal units at  the Comanche Generating Station in Pueblo, and replacing that generation with a combination of wind, solar, battery storage and natural gas. By 2026, when all these projects are complete, more than half of the energy we produce in Colorado will come from renewable sources.Another innovative way to provide  Steel for Fuel ownership opportunities  for shareholders is to buy out existing  power purchase agreements. Late last year we announced agreements to buy two  older wind farms in southern Minnesota  and re-power them with today’s advanced  wind technology. While those always require regulatory approval, we intend to continue to pursue similar opportunities  in 2019 and beyond.Enhancing the Customer ExperienceLeading the clean energy transition positions us to better serve our customers as we develop new programs to help them achieve their sustainability goals. Last year our all-renewable program in Minnesota and Colorado completely sold out. Renewable*Connect gives customers the opportunity to purchase up to 100 percent of certified renewable energy to power their homes and businesses. We have filed plans for a second phase of this program in Minnesota, this time uncapped and scalable, so we can meet the growing demand for this entirely clean energy product. A similar program has been approved in Wisconsin and will provide a greener option for customers starting later in 2019.A growing percentage of customers want to reduce their carbon footprint not only in their homes or businesses, but in the vehicles they drive as well. Electric vehicles are a growing consumer choice, and we are taking a three-pronged approach to help our customers seamlessly make the transition. We have several pilots underway in Minnesota to provide home charging options and public charging infrastructure, and to partner with communities and business customers to convert their fleets from traditional to electric vehicles. We recently announced a $25 million investment in electric vehicle infrastructure and believe these pilots will help our customers reduce energy and meet their sustainability needs. We expect to expand our electric vehicle efforts to other states in 2019 and beyond (read more on pages 10-11).Building a smarter and stronger energy grid that better serves customers is at the heart of our Advanced Grid Intelligence and Security initiative. As technology continues to advance, we are ensuring the way we deliver electricity to homes and businesses keeps improving too. Through this effort we will upgrade our infrastructure, improve security and reliability and leverage advanced meters to provide customers  more choices for managing their energy  use. We will begin installation of new meters in Colorado late in 2019 and plan to file for approval for our advanced grid initiative in Minnesota this year.7

Destination2050Regulatory AdvancementsEffective stakeholder engagement is an important part of generating favorable regulatory outcomes, and we had several regulatory accomplishments in 2018, starting with approvals of our wind projects in Texas and New Mexico. Colorado regulators approved our long-term pricing agreement with EVRAZ, a large steel mill and the second-largest employer in Pueblo. This agreement was crucial for EVRAZ to continue its operation in Pueblo and allow for expansion into the future. One of the largest regulatory issues across our service territory in 2018 was working with our policy makers and stakeholders to determine the best way to distribute tax reform benefits to our customers without negatively impacting our credit metrics. Solutions varied by jurisdiction, but in all, we are in the process of returning more than $300 million of tax benefits to our customers.  Regulators are reviewing our purchase agreement of the Mankato Energy Center, a natural gas facility currently under expansion that has served our customers through a PPA contract. We believe that natural gas will serve as an important  bridge fuel that works well with high  levels of renewable penetration. While we prepare for our next Upper Midwest resource plan that will be filed in the summer of 2019, we will include a dialogue with the Minnesota commission about the importance of operating our nuclear plants through their license periods in the early 2030s. It’s important that we operate our fleet efficiently and effectively, which is exactly what we did in 2018. The fleet delivered energy 96 percent of the time,  while reducing its O&M costs by almost  3 percent (read more on pages 12-13).Operational ExcellenceAt the heart of Xcel Energy’s culture is the commitment to getting better every day. We’ve engaged our employees to find innovative ways to reduce costs and gain efficiencies, and they have delivered. By implementing continuous improvement suggestions from our employees, we saved $59 million of O&M expenses in 2018. We also developed the in-house expertise in lean management techniques to apply continuous improvement efforts to other areas of the business in 2019 and beyond.  Our always-improving mindset is also at work when it comes to safety, of our employees and the public. In 2018, we  built a state-of-the-art natural gas training facility in Minnesota to better train employees and the first responders who we work with in our communities. I am pleased that we had our best public safety performance ever, as measured by gas emergency response, and achieved first quartile performance when it comes to employee safety. We’ve reduced employee injuries by more than 50 percent since we implemented our Journey to Zero employee safety program.Living Our ValuesWe refreshed our corporate values in 2018 to bring a sharp focus and intention to how we want all of our 11,000 employees to approach their work each and every day. These new values — Connected, Committed, Safe and Trustworthy —  were crafted and refined with employees engaged along the way.Exceptional people, grounded in a values-driven organization, is a winning combination that’s getting noticed.  Xcel Energy has been fortunate to receive recognition from publications like Forbes  and Fortune, which have repeatedly listed  us as among the world’s best companies. Utility Dive named Xcel Energy its 2018 Utility of the Year, and we were chosen among the 100 Best Corporate Citizens  by Corporate Responsibility Magazine. One of the things I am most proud of  is our collective commitment to the communities where we serve. In the last year we gave back in a big way, donating more than $11 million and 90,000 volunteer hours to community organizations. Our efforts could be felt in everything from environmental improvements like tree plantings and other greening, to supporting economic self-sufficiency through mentoring and training efforts.As we continue to build the future, we have Destination 2050 squarely in our sights. But as you can see, it is about more than just reducing our carbon footprint and delivering 100-percent carbon-free energy to our customers and communities by 2050. Destination 2050 is about always innovating to deliver best-in-class service to our customers, standing squarely with our communities to help them achieve their energy and economic development goals, engaging with our employees so they can bring their best to work every day and making an impact in our own backyards.Thank you to our customers, shareholders, employees and stakeholders for helping make 2018 an outstanding year for Xcel Energy.Sincerely, Ben Fowke Chairman, President and  Chief Executive Officer   In 2018, Xcel Energy

Destination2050ANNUAL REPORT 2018Wind farms aren’t built just anywhere land is for sale.  They are complex projects that require extensive planning and permitting, significant outreach to neighboring  property owners and other stakeholders, and, of course, regulatory approval.It’s one thing to propose new wind projects. It’s another to shepherd them through the approvals necessary to get new wind farms constructed. Last year, we were able to secure the last of the necessary approvals for one of the largest multi-state wind investments in the country — 12 wind farms in seven states. The first wind project, Rush Creek in Colorado, was completed in 2018.Appropriately, state and local interests drive the discussion. Some communities and regulators are focused on wind energy’s ability to save customers money and to drive economic development. Others are attracted to the fact that more wind energy on our system allows us to continue reducing carbon emissions. What makes our Steel for Fuel strategy of building and owning wind farms widely appealing is its ability to deliver both economic and environmental benefits.New wind farms and the accompanying substations and transmission lines needed to deliver the energy to market are powerful sources of economic development, often in rural areas. Our multi-state wind expansion is expected to create 2,700 construction jobs and 150 full-time positions, and generate $800 million in landowner lease and property tax payments over the lives of the projects.   By 2027, we expect 39 percent of our energy will be supplied by wind — nearly double the amount on our system in 2017. That means wind energy would generate enough clean energy to power approximately six million homes and avoid more than 28 million tons of carbon emissions annually. Colorado Energy Plan Gains ApprovalWe have secured regulatory approval for our Colorado Energy Plan, which will allow  Xcel Energy to deliver on our vision to provide low-cost, clean renewable energy for our customers, stimulate economic development in rural Colorado and substantially reduce our carbon emissions. This project required significant stakeholder outreach and engagement and received support from more than 20 business groups and environmental organizations. The Colorado Energy Plan paves the way for  the early retirement of two coal units at the Comanche Generating Station in Pueblo. When fully executed in 2026, 55 percent of our Colorado energy mix is expected to come from renewable sources while saving customers money on their bills. The first wind project in the Colorado plan — a 500-megawatt wind farm called Cheyenne Ridge — is expected to be completed in late 2020, assuming final regulatory approvals are secured.All charged up  
about driving electric

EV initiative focused on the customer experience

ANNUAL REPORT 2018Twin Cities software engineer Adam Carstensen purchased his first EV — a Tesla Model 3 — in November 2018. A few weeks before delivery, Adam contacted Xcel Energy to set up charging equipment in his garage.The timing was perfect. The Minnesota Public Utilities Commission just approved an EV pilot program to provide advanced home charging equipment for 100 residential customers. The program was advantageous for Adam because the new equipment charges EVs faster than previous technology and includes energy monitoring technology that eliminates the need to install a new dedicated meter and service solely for EV charging. “Once the pilot opened, I responded within a minute. I was one of the first customers in Minnesota to receive the new charging equipment. Not having to install a second meter saved me $1,700 dollars. It was a great experience — very seamless,” Adam said.Adam can drive up to 300 miles on a full charge. He drives his Tesla 25 miles to and from work each workday and uses it for trips throughout the Twin Cities without thinking twice. For longer trips, he plans ahead using an app on his phone that shows where public fast-charging stations are located.Once he’s done driving for the day, Adam plugs in his vehicle at home. At 9:00 each evening, the charging process automatically begins on Xcel Energy’s EV electric pricing plan, which is more than 50 percent lower than standard residential pricing. Because the need for electricity demand falls at night, EV owners are encouraged to save money by charging overnight. Charging an EV on  Xcel Energy’s off-peak plan is the equivalent to approximately 50 cents per gallon.“I save about $40 dollars a month in fuel costs,” said Adam, who also took advantage of a $7,500 federal tax credit. “The bigger savings comes from maintenance. The only regular maintenance I have is rotating the tires and filling up the windshield-washer fluid. There is no engine — no oil changes.”  Although EV customers can realize cost savings compared to traditional vehicles, Adam first began researching hybrid and EVs because of the environmental benefits. Today, a conventional car emits 5.2 tons of carbon dioxide per year. By comparison, EVs charged on Xcel Energy’s system in Minnesota produce only 1.5 tons of carbon per year. That number is expected to drop to 0.4 tons by 2030 as our electricity becomes greener and greener. Adam’s car doesn’t produce any carbon emissions when it’s charged at home because he also participates in our Renewable*Connect program at the 100 percent level, meaning all the electricity in his house comes from certified wind or solar renewable energy sources. “EVs are better for the environment. Climate change is a real problem and this is something that we could do to try and help,” said Adam, who is concerned about the planet his two young children will inherit. Adam Carstensen (left), a participant

13

Destination2050ANNUAL REPORT 2018We’ve long appreciated the value nuclear energy delivers on a number of fronts: the “round-the-clock” affordable energy it provides, the environmental benefits of carbon-free generation, and the $1 billion of annual economic impact to the Minnesota economy where our plants are located. An increasing number of stakeholders have come to appreciate nuclear power for those same reasons. The carbon-free nature of nuclear energy, coupled with its 24x7 power, make it extremely valuable to the clean energy transition. The clean energy transition cannot work if reliability and affordability are not part of the equation. Reliable, affordable and clean must work together, and nuclear energy checks all the boxes.For us, a critical part of our clean energy vision is operating our nuclear units at least through their current licenses, which expire in the early 2030s. We operate three nuclear units in Minnesota — one at Monticello and two units at Prairie Island — that provide 13 percent of our energy mix. Because nuclear energy provides the only carbon-free, always on energy source for our system, it makes pragmatic sense that nuclear remains an important part of our energy future. Employees working at our nuclear plants understand that running those facilities safely, effectively and efficiently is of the utmost importance. During the last few years, we’ve empowered our team to drive innovation to reduce costs — and they’ve delivered. In the last three years, our nuclear employees have eliminated about $40 million of operating and maintenance costs. In 2018, our nuclear employees set a generation record, producing more than 14.6 million megawatt hours of energy, all without a lost-time injury. In addition to working safely, last year the team worked effectively and efficiently, producing power 96 percent of the time while reducing its operating and maintenance costs by nearly  3 percent — a winning formula.We’ve also found innovative ways to reduce fuel costs. By developing a new fuel design, the nuclear engineering team significantly reduced the amount of fuel consumed during operations. This approach extends the period of time between scheduled refueling from 18 months to 24 months, which will save approximately $4 to $5 million per year in fuel costs. Additionally, we expect to generate $70 million in savings over the next 15 years as the need for two refueling outages will be eliminated.Clean, affordable, reliable. Nuclear energy produced in Minnesota continues to check all the boxes.A sight to behold,  
from a distance

ANNUAL REPORT 2018Forty miles north of Denver, a first-of-its-kind unmanned aircraft system flight took place last summer. Very few people saw it — and that’s the point.In 2018, Xcel Energy became the first public utility in the country to receive permission from the Federal Aviation Administration (FAA) to fly drones beyond the operator’s line of sight to inspect transmission lines. The flights, which began in July and continued monthly through the year, are part of a program to prove the value of using unmanned aircraft to inspect critical infrastructure in the power generation industry.The Altus ORC2, a 35-pound drone not available in the retail market, collected images and volumes of data that was then analyzed to identify potential issues that could impact the reliability of the electric transmission grid. More than 1,000 miles of test flights were tracked by a field operations team of four individuals located on the ground — a pilot, an observer and two other team members monitoring the data collection. “FAA team members came to Colorado to observe our transmission inspection flights first hand,” said Eileen Lockhart, who manages Xcel Energy’s UAS program. “They were pleased with the results. If all continues to go well, the program will be expanded to our peer companies in the future.”As a regulated utility, Xcel Energy is required to inspect and perform maintenance on its transmission lines — 24,000 miles of them — on a routine basis. Traditionally we have conducted these inspections with helicopters and foot patrols. Using drones to inspect transmission lines delivers value on many fronts, starting with ensuring the reliability for our customers thanks to better data capture. It’s also safer for our employees, especially in remote mountainous areas, and less expensive, which is one of the many ways we’re working to keep customers’ bills low. As technology improves, the cost to operate drones continues to fall, which saves even more money for customers. Pending FAA approval, we plan to expand this program to inspect transmission lines in other states beginning in 2019. Additionally, we are collaborating with the FAA and the state of North Dakota on the National UAS Integration Pilot Program, an opportunity for state, local, and tribal governments to partner with private-sector entities to work together to accelerate drone integration. Xcel Energy began using drones to conduct indoor inspections in 2013 and expanded the program for outdoor use in 2015. We use drones to inspect everything from boilers to wind towers to our nuclear facilities and everything in between. Xcel Energy became the first public utility to receive

in Puerto Rico 

17

Destination2050ANNUAL REPORT 2018Some of the most rewarding work of 2018 took place more than a thousand miles from our closest service territory. Approximately 200 Xcel Energy line workers and support personnel traveled to Puerto Rico to help restore power following the devastation of Hurricane Maria.Three waves of Xcel Employees flew to Puerto Rico for three-week assignments on the Caribbean island, while our trucks and equipment arrived by barge after being driven to Lake Charles, Louisiana. Xcel Energy crews worked primarily in Caguas, a mountainous and remote region where restoration efforts were challenging due to rugged terrain, narrow roads and overgrown vegetation. Crews worked 16-hour days to safely restore electricity for approximately 6,000 customers, including homes, schools, community centers and one church just in time to hold Easter services. Xcel Energy was among nearly 60 investor-owned electricity companies that collectively dispatched 3,000 line workers and  support personnel to restore power as  part of the industry’s mutual aid program.  Xcel Energy was one of several companies to be recognized with a special 2018 Emergency Assistance Award by the Edison Electric Institute.“Traveling to Puerto Rico was one of  the most rewarding experiences in  my career,” said Lee Nordby, who oversaw  Xcel Energy’s restoration efforts on the island. “Many of the people we encountered had been without power for three or four months, but they were so positive and grateful for our efforts.”Local residents thanked our crews with home-cooked meals, hugs and thank-you signs. One of the most moving events happened at a school where a 12-year-old cried tears of joy after we granted her birthday wish — to restore power after nearly five months in the dark. “It was really powerful,” said Mike Bulger, an operations manager from Colorado. “Our crews restore electricity all over the United States when called upon, but our experience in Puerto Rico was special — something that none of us will ever forget.” Reliable power for the 
world’s biggest stage

A few years ago, a power outage played 
a memorable role at the Super Bowl in 
New Orleans. Xcel Energy was determined 
to make sure that didn’t happen in our 
backyard. As expected, Super Bowl LII 
between the Philadelphia Eagles and the 
New England Patriots went off without a 
hitch in downtown Minneapolis.

It was an honor to provide power for the 
biggest game on the world’s biggest stage 
— more than 103 million people watched 
the game on television. Employees from our 
operations and security teams worked nearly 
two years performing reliability inspections, 
maintaining infrastructure, and identifying 
risk for every possible contingency leading 
up to the game that was played February 4, 
2018 at U.S. Bank Stadium.

Xcel Energy proudly served as the official 
Renewable Energy Provider of the 

Minnesota Super Bowl Host Committee. 
All of the power needed for Super Bowl 
LIVE — a week-long celebration down the 
street from our corporate headquarters on 
Nicollet Mall — was powered through our 
WindSource® program with 100 percent of 
the energy coming from Minnesota wind 
farms. Xcel Energy and Vestas, our wind 
turbine manufacturing supplier, jointly 
sponsored an exhibition at Super Bowl 
LIVE that was staffed by our employee 
volunteers. More than a million people 
participated in a variety of events leading  
up to the big game.

We plan to use the same playbook to ensure 
things go smoothly during the next large 
sporting event in downtown Minneapolis 
— the NCAA Final Four men’s basketball 
championship — that will take place at the 
same location in April 2019.  

A thoughtful approach to 
building a diverse workforce

Xcel Energy co-sponsored an exhibition at  
Super Bowl LIVE, a week-long celebration that 
was powered by 100-percent renewable energy. 
The space included a display for children to 
illuminate the Super Bowl logo in lights. 

It’s important for our workforce to reflect 
the diversity of the communities we 
are privileged to serve. We have taken 
a thoughtful approach to workforce 
development as we know that diverse 
organizations are more successful  
because they bring different strengths  
and perspectives to the table.

This includes expanding our award-winning 
internship programs, creating customized 
diverse hiring and retention plans for select 
business units, developing unconscious bias 
training for all employees and participating 
in the CEO Action for Diversity & Inclusion, 
a national program focused on diverse hiring 
and retention best practices.

For many years, we have been actively 
engaged with high school internship programs 
in the Twin Cities, Denver and Eau Claire, and 
we recently launched a new high school 
internship program in Amarillo, Texas. In 
2018, we hired a record 66 high school 
interns, and the timing couldn’t be better as 
it aligned with the launch of a new social 
media platform developed by Xcel Energy and 
Greater MSP to help Twin Cities companies to 
better track local interns and keep them in the 
pipeline for permanent employment.

We also partner with Legacy i3 — a unique 
program that encourages students from 
underrepresented communities to pursue 
careers in the energy industry and directs 

them to our educational partners who provide 
career training opportunities. This includes 
working with Minnesota State Colleges and 
Universities to guide these students into 
energy-related programs for line workers and 
technical specialists. Xcel Energy employees 
mentor these program participants through 
our Energy Ambassador program.

All these programs help us share with a 
broader audience our story that Xcel Energy

Natural Gas — Natural gas supplies, transportation and storage services for 
power plants are procured to provide an adequate supply of fuel. Remaining 
requirements are procured through a liquid spot market. Generally, natural 
gas supply contracts have variable pricing that is tied to natural gas indices. 
Natural gas supply and transportation agreements include obligations for the 
purchase and/or delivery of specified volumes or payments in lieu of delivery.

For incremental supplies, there are limited on-site fuel storage facilities, with a primary 
reliance on the spot market.

(b)  Majority of natural gas supply under contract is covered by a long-term agreement with 
Anadarko Energy Services Company and the balance of natural gas supply contracts have 
variable pricing features tied to changes in various natural gas indices. PSCo hedges a 
portion of that risk through financial instruments. See Note 10 to the consolidated financial 
statements for further information.

Nuclear  —  NSP-Minnesota  secures  contracts  for  uranium  concentrates, 
uranium conversion, uranium enrichment and fuel fabrication to operate its 
nuclear plants. The contract strategy involves a portfolio of spot purchases 
and medium and long-term contracts for uranium concentrates, conversion 
services and enrichment services with multiple producers and with a focus on 
diversification to minimize potential impacts caused by supply interruptions 
due to geographical and world political issues.

•

Current  nuclear  fuel  supply  contracts  cover  100%  of  uranium 
concentrates requirements through 2021 and approximately 51% of the 
requirements for 2022 - 2033.

Fabrication services for Monticello and PI are 100% committed through 2030 
and 2027, respectively. 

NSP-Minnesota expects sufficient uranium concentrates, conversion services 
and enrichment services to be available for the requirements of its nuclear 
generating plants. Some exposure to market price volatility will remain due to 
index-based pricing structures contained in supply contracts. 

See Item 7 for further information.

NSP-Minnesota’s retail electric rates in Minnesota, North Dakota and South 
Dakota include a FCA for monthly billing adjustments to recover changes in 
prudently incurred costs of fuel related items and purchased energy. Capacity 
costs are recovered through base rates and are not recovered through the 
FCA. Costs associated with MISO are generally recovered through either the 
FCA or base rates.

In 2017, the MPUC voted to change the FCA process in Minnesota. Under 
the  new  process,  each  month  utilities  would  collect  amounts  equal  to  the 
baseline cost of energy set at the start of the plan year (base would be reset 
annually). Monthly variations to the baseline costs would be tracked and netted 
over a 12-month period. Utilities would issue refunds above the baseline costs, 
and  could  seek  recovery  of  any  overage.  Recently,  the  MPUC  delayed 
implementation until January 2020.

Minnesota state law requires NSP-Minnesota to invest 2% of its state electric 
revenues and 0.5% of its state gas revenues in CIP. These costs are recovered 
through an annual cost-recovery mechanism for electric conservation and 
energy management program expenditures.

Energy Sources and Transmission Service Provider

NSP-Minnesota expects to use power plants, power purchases, CIP/DSM 
options, new generation facilities and expansion of power plants to meet its 
system capacity requirements.

Purchased Power — NSP-Minnesota has contracts to purchase power from 
other utilities and IPPs. Long-term purchased power contracts for dispatchable 
resources typically require a capacity charge and an energy charge. NSP-
Minnesota  makes  short-term  purchases  to  meet  system  requirements,  
replace company owned generation, meet operating reserve obligations or 
obtain energy at a lower cost. 

Purchased Transmission Services — NSP-Minnesota and NSP-Wisconsin 
have contracts with MISO and other regional transmission service providers 
to deliver power and energy to their customers.

Wind  Development  —  In  2017,  the  MPUC  approved  NSP-Minnesota’s 
proposal to add 1,550 MW of new wind generation including ownership of 
1,150 MW of wind generation.

In April 2018, the MPUC approved NSP-Minnesota’s petition to build and own 
the Dakota Range, a 300 MW wind project in South Dakota. NSP-Minnesota’s 
capital investment for the Dakota Range is expected to be approximately $350 
million and placed in service in 2021.

In December 2018, the NDPSC approved a settlement agreement for these 
wind development projects.

PPA  Terminations  and Amendments  —  In  June  2018,  NSP-Minnesota 
terminated  the  Benson  and  Laurentian  PPAs,  and  purchased  the  Benson 
biomass facility. As a result, a $103 million regulatory asset was recognized 
for the costs of the Benson transaction. For Laurentian, a regulatory asset of 
$109  million  was  recognized  for  annual  termination  payments/obligations. 
Regulatory approvals provide for recovery of the Benson regulatory asset over 
10 years and Laurentian termination payments as they occur (over six years). 
Termination of the PPAs is expected to save customers over $600 million 
throughout the next 10 years.

Public Utility Regulation

Summary  of  Regulatory Agencies  and Areas  of  Jurisdiction  —  Retail 
rates,  services  and  other  aspects  of  NSP-Minnesota’s  operations  are 
regulated by the MPUC, NDPSC and SDPUC. The MPUC also has regulatory 
authority  over  security  issuances,  certain  property  transfers,  mergers, 
dispositions  of  assets  and  transactions  between  NSP-Minnesota  and  its 
affiliates. In addition, the MPUC reviews and approves NSP-Minnesota’s IRPs 
for meeting future energy needs. In addition, MPUC certifies the need and 
siting for generating plants greater than 50 MW and transmission lines greater 
than 100 KV that will be located within the state. The NDPSC and SDPUC 
have regulatory authority over generation and transmission facilities, along 
with the siting and routing of new generation and transmission facilities in 
North Dakota and South Dakota, respectively.

NSP-Minnesota is subject to the jurisdiction of the FERC for its wholesale 
electric operations, hydroelectric licensing, accounting practices, wholesale 
sales for resale, transmission of electricity in interstate commerce, compliance 
with NERC electric reliability standards, asset transfers and mergers, and 
natural gas transactions in interstate commerce.

NSP-Minnesota  is  a  transmission  owning  member  of  the  MISO  RTO  and 
operates within the MISO RTO and MISO wholesale markets. NSP-Minnesota 
makes wholesale sales in other RTO markets at market-based rates. NSP-
Minnesota and NSP-Wisconsin also make wholesale electric sales at market-
based  prices  to  customers  outside  of  their  balancing  authority  as  jointly 
authorized by the FERC.

Jurisdictional  Cost  Recovery  Allocation  — In  December  2016,  NSP-
Minnesota filed a resource treatment framework with the NDPSC and MPUC. 
The filing proposed a framework to allow NSP-Minnesota’s operations in North 
Dakota and Minnesota to gradually become more independent of one another 
with respect to future generation resource selection while also identifying a 
path for cost sharing of current resources. NSP-Minnesota’s filing identified 
two options: a legal separation, creating a separate North Dakota operating 
company;  or  a  pseudo-separation,  which  maintains  the  current  corporate 
structure but directly assigns the costs and benefits of each resource to the 
jurisdiction  that  supports  it.  Docket  remains  under  consideration  by  the 
NDPSC.

Minnesota  State  ROFR  Statute  Complaint  —  In  September  2017,  LSP 
Transmission  filed a complaint in the Minnesota District Court against the 
Minnesota Attorney General, MPUC and DOC. The complaint was in response 
to MISO assigning NSP-Minnesota and ITC Midwest, LLC to jointly own a 
new 345 KV transmission line from near Mankato, Minnesota to Winnebago, 
Minnesota. The project was estimated by MISO to cost $108 million and was 
assigned  to  NSP-Minnesota  and  ITC  Midwest  as  the  incumbent  utilities, 
consistent with a Minnesota state ROFR statute. The complaint challenged 
the  constitutionality  of  the  state  ROFR  statute  and  is  seeking  declaratory 
judgment  that  the  statute  violates  the  Commerce  Clause  of  the  U.S. 
Constitution and should not be enforced. The Minnesota state agencies and 
NSP-Minnesota filed motions to dismiss. In June 2018, the Minnesota District 
Court  granted  the  defendants’  motions  to  dismiss  with  prejudice.  LSP 
Transmission filed an appeal in July 2018. It is uncertain when a decision will 
be rendered.

Review of PI Costs — As part of NSP-Minnesota’s 2016 multi-year electric 
rate case and IRP, the MPUC ordered an investigation into NSP-Minnesota’s 
PI nuclear investments. The issue was resolved as part of the 2016 multi-year 
electric rate case settlement. In November 2018, the DOC issued a final report, 
in which no cost disallowances were recommended.

Nuclear Spent Fuel Storage — NSP-Minnesota has interim on-site storage 
for  spent  nuclear  fuel  at  its  Monticello  and  PI  nuclear  generating  plants. 
Authorized storage capacity is sufficient to allow NSP-Minnesota to operate 
until the end of the operating licenses in 2030 for Monticello, 2033 for PI Unit 
1,  and  2034  for  PI  Unit  2. Authorizations  for  additional  spent  fuel  storage 
capacity may be required at each site to support either continued operation 
or decommissioning if the federal government does not commence storage 
operations.

In 2013, NSP-Minnesota’s Monticello nuclear generating plant loaded and 
placed  five  storage  canisters  (canisters  #11-15)  in  the  ISFSI  and  a  sixth 
canister (canister #16) was loaded but remained in the plant pending resolution 
of weld inspection issues. Successful pressure and leak testing demonstrated 
the  safety  and  integrity  of  all  six  canisters  involved.  NSP-Minnesota  took 
several  actions  to  assure  compliance  with  the  NRC’s  regulations  and 
Monticello’s  storage  license.  The  NRC  has  approved  NSP-Minnesota’s 
compliance plan for all canisters. 

NSP-Minnesota intends to seek recovery of these costs in a future regulatory 
proceeding. No public safety issues have been raised, or are believed to exist, 
in this matter.

See Note 12 to the consolidated financial statements for further information.

Nuclear Power Operations and Waste Disposal

Wholesale and Commodity Marketing Operations

NSP-Minnesota owns two nuclear generating plants: the Monticello plant and 
the PI plant. Nuclear power plant operations produce gaseous, liquid and solid 
radioactive  wastes  which  are  controlled  by  federal  regulation.  High-level 
radioactive wastes primarily include used nuclear fuel. LLW consists primarily 
of demineralizer resins, paper, protective clothing, rags, tools and equipment 
that have become contaminated through use in a plant.

NRC  Regulation  —  The  NRC  regulates  nuclear  operations.  Costs  of 
complying with NRC requirements can affect both operating expenses and 
capital investments of the plants. NSP-Minnesota has obtained recovery of 
these compliance costs in customer rates and expects future compliance costs 
will continue to be recoverable.

LLW Disposal — LLW from NSP-Minnesota’s Monticello and PI nuclear plants 
is currently disposed at the Clive facility located in Utah and the Waste Control 
Specialists facility located in Texas. If off-site LLW disposal facilities become 
unavailable, NSP-Minnesota has storage capacity available on-site at PI and 
Monticello which would allow both plants to continue to operate until the end 
of their current licensed lives.

High-Level Radioactive Waste Disposal — The federal government has 
responsibility to permanently dispose domestic spent nuclear fuel and other 
high-level radioactive wastes. The Nuclear Waste Policy Act requires the DOE 
to  implement  a  program  for  nuclear  high-level  waste  management.  This 
includes the siting, licensing, construction and operation of a repository for 
spent nuclear fuel from civilian nuclear power reactors and other high-level 
radioactive wastes at a permanent federal storage or disposal facility. The 
federal  government  has  been  evaluating  a  nuclear  geologic  repository  at 
Yucca Mountain, Nevada for many years. Currently, there are no definitive 
plans for a permanent federal storage facility at Yucca Mountain or any other 
site.

NSP-Minnesota conducts various wholesale marketing operations, including 
the  purchase  and  sale  of  electric  capacity,  energy,  ancillary  services  and 
energy-related  products.  NSP-Minnesota  uses  physical  and  financial 
instruments to minimize commodity price and credit risk and hedge sales and 
purchases.  NSP-Minnesota  also  engages  in  trading  activity  unrelated  to 
hedging and sharing of any margins is determined through state regulatory 
proceedings  as  well  as  the  operation  of  the  FERC  approved  JOA.  NSP-
Minnesota does not serve any wholesale requirements customers at cost-
based regulated rates.

NSP-Wisconsin

Public Utility Regulation

Summary  of  Regulatory Agencies  and Areas  of  Jurisdiction  —  Retail 
rates,  services  and  other  aspects  of  NSP-Wisconsin’s  operations  are 
regulated  by  the  PSCW  and  the  MPSC.  In  addition,  each  of  the  state 
commissions  certifies  the  need  for  new  generating  plants  and  electric 
transmission lines before the facilities may be sited and built. NSP-Wisconsin 
is subject to the jurisdiction of the FERC for its wholesale electric operations, 
hydroelectric generation licensing, accounting practices, wholesale sales for 
resale, transmission of electricity  in interstate commerce, compliance with 
NERC  electric  reliability  standards,  asset  transactions  and  mergers  and 
natural  gas  transactions  in  interstate  commerce.  NSP-Wisconsin  is  a 
transmission owning member of the MISO RTO that operates within the MISO 
RTO and wholesale energy market. NSP-Wisconsin and NSP-Minnesota are 
jointly authorized by the FERC to make wholesale electric sales at market-
based prices. 

The PSCW has a biennial base rate filing requirement. By June of each odd 
numbered year, NSP-Wisconsin must submit a rate filing for the test year 
beginning the following January.

10

Fuel  and  Purchased  Energy  Cost  Recovery  Mechanisms  —  NSP-
Wisconsin  does  not  have  an  automatic  electric  fuel  adjustment  clause. 
Instead, under Wisconsin rules, utilities submit a forward-looking annual fuel 
cost plan to the PSCW. Once the PSCW approves the fuel cost plan, utilities 
defer the amount of any fuel cost under-recovery or over-recovery in excess 
of a 2% annual tolerance band, for future rate recovery or refund. Approval 
of a fuel cost plan and any rate adjustment for refund or recovery of deferred 
costs is determined by the PSCW. Rate recovery of deferred fuel cost is subject 
to an earnings test based on the utility’s most recently authorized ROE. Fuel 
cost under-collections that exceed the 2% annual tolerance band may not be 
recovered if the utility earnings for that year exceed the authorized ROE.

NSP-Wisconsin’s electric fuel costs for 2018 were lower than authorized in 
rates and outside the 2% annual tolerance band, primarily due to greater than 
forecasted generation sales into the MISO market and lower purchased power 
costs  coupled  with  moderate  weather. Under  the  fuel  cost  recovery  rules, 
NSP-Wisconsin retained approximately $3.6 million of fuel costs and deferred 
approximately $2.8 million. NSP-Wisconsin will file a reconciliation of 2018 
fuel costs with the PSCW by March 31, 2019. 

NSP-Wisconsin’s retail electric rate schedules for Michigan customers include 
power supply cost recovery factors, which are based on 12-month projections. 
After  each  12-month  period,  a  reconciliation  is  submitted  whereby  over-
recoveries  are  refunded  and  any  under-recoveries  are  collected  from 
customers.

Wisconsin Energy Efficiency Program — The primary energy efficiency 
program  is  funded  by  the  state’s  utilities,  but  operated  by  independent 
contractors subject to oversight by the PSCW and utilities. NSP-Wisconsin 
recovers these costs from retail customers.

Transmission Initiatives

NSP-Wisconsin  operates  an  integrated  system  with  NSP-Minnesota.  See 
NSP-Minnesota-Energy Sources and Transmission Service Provider.

NSP-Wisconsin / American Transmission Company, LLC - La Crosse to 
Madison, WI Transmission Line — In December 2018, construction was 
completed on the Badger Coulee 345 KV transmission line. The line extends 
from La Crosse, WI. to Madison, WI. NSP-Wisconsin’s half of the line is shared 
with Dairyland Power Cooperative, WPPI Energy and Southern Minnesota 
Municipal Power Agency-Wisconsin.

Wholesale and Commodity Marketing Operations

NSP-Wisconsin does not serve any wholesale requirements customers at 
cost-based regulated rates. 

PSCo

Public Utility Regulation

Summary of Regulatory Agencies and Areas of Jurisdiction — PSCo is 
regulated by the CPUC with respect to its facilities, rates, accounts, services 
and issuance of securities. PSCo is regulated by the FERC for its wholesale 
electric operations, accounting practices, hydroelectric licensing, wholesale 
sales for resale, transmission of electricity in interstate commerce, compliance 
with the NERC electric reliability standards, asset transactions and mergers 
and natural gas transactions in interstate commerce. PSCo is not presently 
a member of an RTO and does not operate within an RTO energy market.  
However, PSCo does make certain sales to other RTO’s, including SPP.  PSCo 
makes  wholesale  electric  sales  at  cost-based  prices  to  customers  inside 
PSCo’s balancing authority area and at market-based prices to customers 
outside PSCo’s balancing authority area as authorized by the FERC.

Fuel, Purchased Energy and Conservation Cost-Recovery 
Mechanisms

• 

• 

• 

• 

• 

ECA — Recovers fuel and purchased energy costs. Short-term sales 
margins are shared with retail customers through the ECA. The ECA is 
revised quarterly.

PCCA — Recovers purchased capacity payments.

SCA — Recovers the difference between PSCo’s actual cost of fuel and 
costs recovered under its steam service rates.  The SCA rate is revised 
quarterly.

DSMCA — Recovers DSM, interruptible service costs and performance 
initiatives for achieving energy savings goals.

RESA — Recovers the incremental costs of compliance with the RES 
with a maximum of 2% of the customer’s bill.

•  WCA — Recovers costs for customers who choose renewable resources.

• 

• 

TCA — Recovers costs for transmission investment outside of rate cases.

CACJA — Recovers costs associated with the CACJA.

PSCo recovers fuel and purchased energy costs from its wholesale electric 
customers  through  a  fuel  cost  adjustment  clause  approved  by  the  FERC. 
Wholesale customers pay their jurisdictional allocation of production costs 
through a fully forecasted formula rate with true-up.

Energy Sources and Transmission Service Providers

PSCo  expects  to  meet  its  system  capacity  requirements  through  electric 
generating stations, power purchases, new generation facilities, DSM options 
and expansion of generation plants.

Purchased Power — PSCo purchases power from other utilities and IPPs. 
Long-term purchased power contracts for dispatchable resources typically 
require capacity and energy charges. It also contracts to purchase power for 
both wind and solar resources. PSCo makes short-term purchases to meet 
system  load  and  energy  requirements,  replace  owned  generation,  meet 
operating reserve obligations, or obtain energy at a lower cost.

Purchased  Transmission  Services  —  In  addition  to  using  its  own 
transmission system, PSCo has contracts with regional transmission service 
providers to deliver energy to its customers.

Wind Development — In 2018, PSCo completed construction and placed in 
service its Rush Creek 600 MW wind farm in Colorado.

CEP  —  In  September  2018,  the  CPUC  approved  PSCo’s  preferred  CEP 
portfolio,  which  included  the  retirement  of  two  coal-fired  generation  units, 
Comanche Unit 1 (in 2022) and Comanche Unit 2 (in 2025), and the following 
additions:

PSCo’s  investment  is  expected  to  be  approximately  $1  billion,  including 
transmission to support the increase in renewable generation. This investment 
includes the 500 MW Cheyenne Ridge wind farm and 345 KV generation tie 
line, as well as the Shortgrass Substation. CPCNs for these projects were 
filed in December 2018.  A CPUC decision is anticipated by May 2019. CPCNs 
for the natural gas generation facility are anticipated to be filed by mid-2019.

Boulder  Municipalization  —  In  2011,  Boulder  passed  a  ballot  measure 
authorizing  the  formation  of  an  electric  municipal  utility,  subject  to  certain 
conditions.  Subsequently,  there  have  been  various  legal  proceedings  in 
multiple venues with jurisdiction over Boulder’s plan. In 2014, the Boulder City 
Council passed an ordinance to establish an electric utility. PSCo challenged 
the formation of this utility and the Colorado Court of Appeals ruled in PSCo’s 
favor, vacating a lower court decision. In June 2018, the Colorado Supreme 
court rejected Boulder’s request to dismiss the case and remanded it to the 
Boulder District Court.

• 

• 

• 

• 

Boulder has filed multiple separation applications with the CPUC, which have 
been challenged by PSCo and other intervenors. In September 2017, the 
CPUC issued a written decision, agreeing with several key aspects of PSCo’s 
position.  The  CPUC  has  approved  the  designation  of  some  electrical 
distribution assets for transfer, subject to Boulder completing certain filings. 
Those  filings  were  submitted  in  the  fourth  quarter  of  2018.  Subsequently, 
various parties requested the CPUC commence additional processes; the 
form of such processes is currently under consideration. In the fourth quarter 
of  2018,  Boulder’s  City  Council  also  adopted  an  Ordinance  authorizing 
Boulder  to  begin  negotiations  for  the  acquisition  of  certain  property  or  to 
otherwise condemn that property after Feb. 1, 2019.  In the first quarter of 
2019,  Boulder  sent  PSCo  a  Notice  of  Intent  to  acquire  certain  electric 
distribution assets. 

Boulder does not have authorization from the CPUC to initiate a condemnation 
proceeding at this time.

Wholesale and Commodity Marketing Operations

PSCo  conducts  various  wholesale  marketing  operations,  including  the 
purchase and sale of electric capacity, energy, ancillary services and energy 
related products. PSCo uses physical and financial instruments to minimize 
commodity price and credit risk and hedge sales and purchases. PSCo also 
engages in trading activity unrelated to hedging and sharing of any margins 
is determined through state regulatory proceedings as well as the operation 
of the FERC approved JOA.

SPS

Public Utility Regulation

Summary of Regulatory Agencies and Areas of Jurisdiction — The PUCT 
and NMPRC regulate SPS’ retail electric operations and have jurisdiction over 
its retail rates and services and the construction of transmission or generation 
in their respective states. The municipalities in which SPS operates in Texas 
have  original  jurisdiction  over  SPS’  rates  in  those  communities.  The 
municipalities’ rate setting decisions are subject to PUCT review.

SPS is regulated by the FERC for its wholesale electric operations, accounting 
practices,  wholesale  sales  for  resale,  the  transmission  of  electricity  in 
interstate  commerce,  compliance  with  NERC  electric  reliability  standards, 
asset transactions and mergers, and natural gas transactions in interstate 
commerce.  SPS  is  a  transmission-owning  member  of  the  SPP  RTO  and 
operates  within  the  SPP  RTO  and  SPP  IM  wholesale  market.  SPS  is 
authorized to make wholesale electric sales at market-based prices. 

Fuel, Purchased Energy and Conservation Cost-Recovery 
Mechanisms — 

• 

• 

• 

DCRF — Recovers distribution costs not included in rates in Texas.

EECRF — Recovers costs for energy efficiency programs in Texas.

EE rider — Recovers costs for energy efficiency programs in New Mexico.

FPPCAC — Adjusts monthly to recover the actual fuel and purchased 
power costs in New Mexico.

PCRF — Allows recovery of purchased power costs not included in rates 
in Texas.

RPS — Recovers deferred costs for renewable energy programs in New 
Mexico.

TCRF  —  Recovers  certain  transmission  infrastructure  improvement 
costs and changes in wholesale transmission charges not included in 
base rates in Texas.

The fixed fuel and purchased energy recovery factor provides for the over- or 
under-recovery  of  energy  expenses.  Regulations  require  refunding  or 
surcharging over- or under- recovery amounts, including interest, when they 
exceed 4% of the utility’s annual fuel and purchased energy costs on a rolling 
12-month basis, if this condition is expected to continue.

SPS recovers fuel and purchased energy costs from its wholesale customers 
through  a  monthly  wholesale  fuel  and  purchased  energy  cost  adjustment 
clause accepted by the FERC. Wholesale customers also pay the jurisdictional 
allocation of production costs.

Energy Sources and Transmission Service Providers

SPS expects to use electric generating stations, power purchases, DSM and 
new generation options to meet its system capacity requirements. In addition, 
it has evaluated water supply issues at the Tolk facility, concluding additional 
resource investment will be required to operate the plant through its existing 
life.  The  Ogallala  aquifer  has  depleted  more  rapidly  than  expected.  SPS 
installed  a  horizontal  water  well  that  may  help  delay  the  need  for  a  more 
substantial  investment  solution.  As  a  result  of  this  issue  and  future 
environmental rules facing the plant, it sought a decrease to the remaining 
life of the facility in the 2017 Texas and New Mexico rate case proceedings.

Purchased Power — SPS purchases power from other utilities and IPPs. 
Long-term purchased power contracts typically require periodic capacity and 
energy charges. SPS also makes short-term purchases to meet system load 
and  energy  requirements  to  replace  owned  generation,  meet  operating 
reserve obligations or obtain energy at a lower cost.

Purchased Transmission Services — SPS has contractual arrangements 
with SPP and regional transmission service providers to deliver power and 
energy to its native load customers.

Wind  Development  —  In  2018,  the  NMPRC  and  PUCT  approved  SPS’ 
proposal  to  add  1,230  MW  of  new  wind  generation,  including  1,000  MW 
ownership.

In  March  2018,  the  NMPRC  approved  SPS’  petition  to  build  and  own 
Sagamore, a 522 MW wind project in New Mexico which is expected to be 
placed into service in 2020. In May 2018, the PUCT approved SPS’ petition 
to  build  and  own  Hale  County,  a  478  MW  wind  project  in Texas  which  is 
expected to be placed into service in 2019. Both projects qualify for 100% of 
PTCs.  SPS’  capital  investment  for  these  wind  projects  is  expected  to  be 
approximately $1.6 billion.

Texas State ROFR Request for Declaratory Order — In 2017, SPS and 
SPP filed a joint petition with the PUCT for a declaratory order regarding SPS’ 
ROFR. SPS contended that Texas law grants an incumbent electric utility the 
ROFR to construct new transmission facilities located in the utility’s service 
area. The PUCT subsequently issued  an order finding that SPS does not 
possess an exclusive right to construct and operate transmission facilities. In 
January 2018, SPS and two other parties filed appeals in the Texas State 
District  Court.  In  September  2018,  the  District  Court  affirmed  the  PUCT’s 
ROFR order. SPS has filed an additional appeal.

NSP-Minnesota

Public Utility Regulation

Summary  of  Regulatory Agencies  and Areas  of  Jurisdiction  —  Retail 
rates,  services  and  other  aspects  of  NSP-Minnesota’s  retail  natural  gas 
operations are regulated by the MPUC and NDPSC. The MPUC has regulatory 
authority  over  security  issuances,  certain  property  transfers,  mergers  with 
other utilities and transactions between NSP-Minnesota and its affiliates. The 
MPUC reviews and approves NSP-Minnesota’s natural gas supply plans for 
meeting future energy needs. NSP-Minnesota is subject to the jurisdiction of 
the  FERC  with  respect  to  certain  natural  gas  transactions  in  interstate 
commerce. NSP-Minnesota is also subject to the DOT, Minnesota Office of 
Pipeline Safety, NDPSC and SDPUC for pipeline safety compliance.

Purchased Gas and Conservation Cost-Recovery Mechanisms — NSP-
Minnesota’s retail natural gas rates for Minnesota and North Dakota include 
a PGA clause that provides for prospective monthly rate adjustments to reflect 
the  forecasted  cost  of  purchased  natural  gas,  transportation  and  storage 
service.  The  annual  difference  between  the  natural  gas  cost  revenues 
collected through PGA rates and the actual natural gas costs is collected or 
refunded over the subsequent 12-month period. 

NSP-Minnesota  also  recovers  costs  associated  with  transmission  and 
distribution pipeline integrity management programs through its GUIC rider. 
Costs  recoverable  under  the  GUIC  rider  include  funding  for  pipeline 
assessments as well as deferred costs from NSP-Minnesota’s existing sewer 
separation and pipeline integrity management programs.

NSP-Wisconsin

Public Utility Regulation

NSP-Wisconsin is subject to the jurisdiction of the FERC with respect to 
natural gas transactions in interstate commerce. NSP-Wisconsin is subject 
to the DOT, PSCW and MPSC for pipeline safety compliance.

Natural Gas Cost-Recovery Mechanisms — NSP-Wisconsin has a retail 
PGA cost-recovery mechanism for Wisconsin to recover the actual cost of 
natural gas and transportation and storage services.

NSP-Wisconsin’s natural gas rates for Michigan customers include a 
natural gas cost-recovery factor, which is based on 12-month projections 
and trued-up to actual amounts on an annual basis.

PSCo

Public Utility Regulation

Summary of Regulatory Agencies and Areas of Jurisdiction — PSCo is 
regulated by the CPUC with respect to its facilities, rates, accounts, services 
and issuance of securities. PSCo holds a FERC certificate that allows it to 
transport natural gas in interstate commerce without PSCo becoming subject 
to full FERC jurisdiction. PSCo is subject to the DOT and CPUC with regards 
to pipeline safety compliance.

Purchased Natural Gas and Conservation Cost-Recovery Mechanisms 

GCA — Recovers the costs of purchased natural gas and transportation 
to  meet  customer  requirements  and  is  revised  quarterly  to  allow  for 
changes in natural gas rates.

SPS

Natural Gas Facilities Used for Electric Generation

SPS does not provide retail natural gas service, but purchases and transports 
natural  gas  for  its  generation  facilities  and  operates  natural  gas  pipeline 
facilities connecting the generation facilities to interstate natural gas pipelines. 
SPS is subject to the jurisdiction of the FERC with respect to natural gas 
transactions in interstate commerce and the PHMSA and PUCT for pipeline 
safety compliance.

GENERAL

Seasonality

Demand for electric power and natural gas is affected by seasonal differences 
in the weather. In general, peak sales of electricity occur in the summer months 
and peak sales of natural gas occur in the winter months. As a result, the 
overall  operating  results  may  fluctuate  substantially  on  a  seasonal  basis. 
Additionally,  Xcel  Energy’s  operations  have  historically  generated  less 
revenues and income when weather conditions are milder in the winter and 
cooler in the summer. 

See Item 7 for further information.

Competition

Summary of Regulatory Agencies and Areas of Jurisdiction — NSP-
Wisconsin is regulated by the PSCW and MPSC. The PSCW has a biennial 
base-rate filing requirement. By June of each odd-numbered year, NSP-
Wisconsin must submit a rate filing for the test year period beginning the 
following January.

Xcel Energy is a vertically integrated utility subject to traditional cost-of-service 
regulation by state public utilities commissions. Xcel Energy is subject to public 
policies that promote competition and development of energy markets. Xcel 
Energy’s  industrial  and  large  commercial  customers  have  the  ability  to 
generate their own electricity. In addition, customers may have the option of 
substituting other fuels or relocating their facilities to a lower cost region. 

14

initiatives 

There  are  significant  present  and  future  environmental  regulations  to 
encourage use of clean energy technologies and regulate emissions of GHGs. 
Xcel  Energy  has  undertaken  numerous 
to  meet  current 
requirements  and  prepare  for  potential  future  regulations,  reduce  GHG 
emissions  and  respond  to  state  renewable  and  energy  efficiency  goals.  If 
future environmental regulations do not provide credit for the investments Xcel 
Energy has already made or if they require additional initiatives or emission 
reductions, substantial costs may be incurred. The EPA, as an alternative to 
the  CPP,  has  proposed  a  new  regulation  that,  if  adopted,  would  require 
implementation  of  heat  rate  improvement  projects  at  our  coal-fired  power 
plants. It is not known what those costs might be until a final rule is adopted 
and state plans are developed to implement a final regulation. Xcel Energy 
believes, based on prior state commission practice, the cost of these initiatives 
or replacement generation would be recoverable through rates.

Xcel Energy is committed to addressing climate change and potential climate 
change regulation through efforts to reduce its GHG emissions in a balanced, 
cost-effective manner. Starting in 2011, Xcel Energy began reporting GHG 
emissions under the EPA’s mandatory GHG Reporting Program.

Xcel Energy estimates that in 2018, it reduced the CO2 emissions associated 
with  the  electric  generating  resources  used  to  serve  its  customers  by 
approximately 40% from 2005 levels. This reduction accounts for emissions 
from electric generating plants owned by Xcel Energy as well as purchased 
power. 

Xcel Energy primarily relied on strategies that resulted in:

• 

• 

• 

Development of renewable energy facilities;

Retirement and replacement of existing generating plants; and,

Customer energy efficiency programs.

CAPITAL SPENDING AND FINANCING

See Item 7 for a discussion of expected capital expenditures and funding 
sources.

EMPLOYEES

As of Dec. 31, 2018, Xcel Energy had 11,043 full-time employees and 49 
part-time employees, of which 5,129 were covered under CBAs.

Customers have the opportunity to supply their own power with distributed 
generation  including,  but  not  limited  to,  solar  generation  and  in  most 
jurisdictions  can  currently  avoid  paying  for  most  of  the  fixed  production, 
transmission and distribution costs incurred to serve them. Several states 
have  policies  designed  to  promote  the  development  of  solar  and  other 
distributed energy resources through incentive policies. With these incentives 
and  federal  tax  subsidies,  distributed  generating  resources  are  potential 
competitors to Xcel Energy’s electric service business.

The FERC has continued to promote competitive wholesale markets through 
open access transmission and other means. As a result, Xcel Energy Inc.’s 
utility subsidiaries and their wholesale customers can purchase the output 
from  generation  resources  of  competing  wholesale  suppliers  and  use  the 
transmission systems of the utility subsidiaries on a comparable basis to serve 
their native load.

FERC Order No. 1000 seeks to establish competition for construction and 
operation  of  certain  new  electric  transmission  facilities.  State  utilities 
commissions have also created resource planning programs that promote 
competition  for  electricity  generation  resources  used  to  provide  service  to 
retail customers. 

Xcel Energy Inc.’s utility subsidiaries have franchise agreements with cities 
subject to periodic renewal, however, a city could seek alternative means to 
access electric power or gas, such as municipalization. 

While each of Xcel Energy Inc.’s utility subsidiaries faces these challenges, 
Xcel  Energy  believes  their  rates  and  services  are  competitive  with  the 
alternatives currently available.

ENVIRONMENTAL MATTERS

Xcel  Energy’s  facilities  are  regulated  by  federal  and  state  environmental 
agencies that have jurisdiction over air emissions, water quality, wastewater 
discharges,  solid  wastes  and  hazardous  substances.  Various  company 
activities require registrations, permits, licenses, inspections and approvals 
from these agencies. Xcel Energy has received all necessary authorizations 
for the construction and continued operation of its generation, transmission 
and distribution systems. Xcel Energy’s facilities have been designed and 
constructed to operate in compliance with applicable environmental standards 
and related monitoring and reporting requirements. However, it is not possible 
to determine when or to what extent additional facilities or modifications of 
existing  or  planned  facilities  will  be  required  as  a  result  of  changes  to 
environmental  regulations,  interpretations  or  enforcement  policies  or  what 
effect future laws or regulations may have upon Xcel Energy’s operations. 
Xcel Energy will likely be required to incur capital expenditures in the future 
to comply with requirements for remediation of MGP and other legacy sites. 
The scope and timing of these expenditures cannot be determined until more 
information is obtained regarding the need for remediation at legacy sites. 

In Minnesota, Texas and Wisconsin, Xcel Energy must comply with emission 
budgets that require the purchase of emission allowances from other utilities. 
The Denver North Front Range Nonattainment Area does not meet either the 
2008  or  2015  ozone  NAAQS.  Colorado  will  continue  to  consider  further 
reductions available in the non-attainment area as it develops plans to meet 
ozone standards. Gas plants which operate in PSCo’s non-attainment area 
may be required to improve or add controls, implement further work practices 
and/or implement enhanced emissions monitoring as part of future Colorado 
state plans.

A key accountability of the Board of Directors is the oversight of material risk, 
and  our  Board  of  Directors  employs  an  effective  process  for  doing  so. 
Management and each Board of Directors’ committee have responsibility for 
overseeing  the  identification  and  mitigation  of  key  risks  and  reporting  its 
assessments and activities to the full Board of Directors.

Management identifies and analyzes risks to determine materiality and other 
attributes  such  as  timing,  probability  and  controllability.  Identification  and 
analysis occurs formally through a key risk assessment conducted by senior 
management,  the  financial  disclosure  process,  hazard  risk  management 
procedures  and  internal  auditing  and  compliance  with  financial  and 
operational controls. Management also identifies and analyzes risk through 
its business planning process and development of goals and key performance 
indicators,  which  include  risk  identification  to  determine  barriers  to 
implementing Xcel Energy’s strategy. The business planning process also 
identifies areas in which there is a potential for a business area to assume 
inappropriate risk to meet goals and determines how to prevent inappropriate 
risk-taking.

Xcel Energy  has a  robust compliance  program  and promotes  a culture  of 
compliance, including tone at the top. The process for risk mitigation includes 
adherence to our code of conduct and compliance policies, operation of formal 
risk management structures and overall business management to mitigate 
the risks inherent in the implementation of strategy. Xcel Energy manages 
and  further  mitigates  risks  through  formal  risk  management  structures, 
including management councils, risk committees and services of corporate 
areas such as internal audit, corporate controller and legal. 

Management communicates regularly with the Board of Directors and key 
stakeholders regarding risk. Senior management presents and communicates 
a  periodic  risk  assessment  to  the  Board  of  Directors  which  provides 
information  on  the  risks  management  believes  are  material,  including  the 
earnings impact, timing, likelihood and controllability.

The Board of Directors approaches oversight, management and mitigation of 
risk as an integral and continuous part of its governance of Xcel Energy. The 
Board of Directors regularly reviews management’s key risk assessment and 
analyzes areas of existing and future risks and opportunities. In addition, the 
Board of Directors assigns oversight of critical risks to its four committees to 
ensure these risks are well understood and given appropriate focus. The Audit 
Committee is responsible for reviewing the adequacy of risk oversight and 
affirming that appropriate oversight occurs. Oversight of cybersecurity risks 
by the Operations, Nuclear, Environmental and Safety Committee includes 
receiving  independent  outside  assessments  of  cybersecurity  maturity  and 
assessment of plans.

New  risks  are  considered  and  assigned  as  appropriate  during  the  annual 
Board of Directors’ and committee evaluation process. Committee charters 
and annual work plans are updated accordingly. Committees regularly report 
on their oversight activities and certain risk issues may be brought to the full 
Board of Directors for consideration when deemed appropriate. Finally, the 
Board of Directors conducts an annual strategy session where Xcel Energy’s 
future plans and initiatives are reviewed.

Risks Associated with Our Business

Operational Risks

Our natural gas and electric transmission and distribution operations 
involve numerous risks that may result in accidents and other operating 
risks and costs.

Our  natural  gas  transmission  and  distribution  activities  include  inherent 
hazards  and  operating  risks,  such  as  leaks,  explosions,  outages  and 
mechanical problems. Our electric transmission and distribution activities also 
include inherent hazards and operating risks such as contact, fire and outages 
which could cause substantial financial losses. These natural gas and electric 
risks could result in loss of life, significant property damage, environmental 
pollution, impairment of our operations and substantial losses. We maintain 
insurance against some, but not all, of these risks and losses. The occurrence 
of these events, if not fully covered by insurance, could have a material effect 
on our financial condition, results of operations and cash flows.

Additionally, for natural gas costs that may be required in order to comply with 
potential  new  regulations,  including  the  Pipeline  Safety  Act,  could  be 
significant. 

The Pipeline Safety Act requires verification of pipeline infrastructure records 
by pipeline owners and operators to confirm the maximum allowable operating 
pressure  of  lines  located  in  high  consequence  areas  or  more-densely 
populated  areas.  We  have  programs  in  place  to  comply  with  the  Pipeline 
Safety Act and for systematic infrastructure monitoring and renewal over time. 
A significant incident could increase regulatory scrutiny and result in penalties 
and higher costs of operations.

The PHMSA is responsible for administering the DOT’s national regulatory 
program to assure the safe transportation of natural gas, petroleum and other 
hazardous  materials  by  pipelines.  The  PHMSA  continues  to  develop 
regulations and other approaches to risk management to assure safety in 
design,  construction,  testing,  operation,  maintenance  and  emergency 
response of natural gas pipeline infrastructure.

Our utility operations are subject to long-term planning risks.

Most  electric  utility  investments  are  planned  to  be  used  for  decades. 
Transmission and generation investments typically have long lead times and 
are planned well in advance of when they are brought in-service subject to 
long-term resource plans. These plans are based on numerous assumptions 
such as: sales growth, customer usage, commodity prices, economic activity, 
costs, regulatory mechanisms, customer behavior, available technology and 
public policy.

The electric utility sector is undergoing a period of significant change. For 
example, increases in appliance, lighting and energy efficiency, wider adoption 
and lower cost of renewable generation and distributed generation, shifts away 
from coal generation to decrease CO2 emissions and increasing use of natural 
gas  in  electric  generation  driven  by  lower  natural  gas  prices.  Customer 
adoption of these technologies and increased energy efficiency could result 
in excess transmission and generation resources as well as stranded costs 
if Xcel Energy is not able to fully recover the costs and investments. These 
changes also introduce additional uncertainty into long-term planning which 
gives rise to a risk that the magnitude and timing of resource additions and 
growth in customer demand may not coincide and that the preference for the 
types of additions may change from planning to execution. In addition, we are 
subject to longer-term availability of the natural resource inputs such as coal, 
natural gas, uranium and water to cool our facilities. Lack of availability of 
these resources could jeopardize long-term operations of our facilities or make 
them uneconomic to operate. 

17

Changing customer expectations and technologies are requiring significant 
investments in advanced grid infrastructure. This increases the exposure to 
potential outdating of technologies and resultant risks. The inability of coal 
mining  companies  to  attract  capital  could  disrupt  longer-term  supplies. 
Decreasing use per customer driven by appliance and lighting efficiency and 
the  availability  of  cost-effective  distributed  generation  places  downward 
pressure on sales growth. This may lead to under recovery of costs, excess 
resources to meet customer demand and increases in electric rates. Finally, 
multiple states may not agree as to the appropriate resource mix and the 
differing views may lead to costs incurred to comply with one jurisdiction that 
are not recoverable across all of the jurisdictions served by the same assets. 

Our  subsidiary,  NSP-Minnesota,  is  subject  to  the  risks  of  nuclear 
generation.

NSP-Minnesota’s two nuclear stations, PI and Monticello, subject it to the risks 
of nuclear generation, which include:

• 

• 

• 

Risks associated with use of radioactive material in the production of 
energy, the management, handling, storage and disposal of radioactive 
materials;

Limitations on insurance available to cover losses that might arise in 
connection with nuclear operations, as well as obligations to contribute 
to an insurance pool in the event of damages at a covered U.S. reactor; 
and,

the 

Uncertainties  with 
financial  aspects  of 
technological  and 
decommissioning nuclear plants. For example, assumptions regarding 
decommissioning costs may change based on economic conditions and 
changes  in  the  expected  life  of  the  asset  may  cause  our  funding 
obligations to change.

The NRC has authority to impose licensing and safety-related requirements 
for the operation of nuclear generation facilities. The NRC has the authority 
to impose fines and/or shut down a unit until compliance is achieved. Revised 
NRC safety requirements could necessitate substantial capital expenditures 
or an increase in operating expenses. In addition, the Institute for Nuclear 
Power Operations reviews NSP-Minnesota’s nuclear operations and nuclear 
generation  facilities.  Compliance  with  the  Institute  for  Nuclear  Power 
Operations’ recommendations could result in substantial capital expenditures 
or a substantial increase in operating expenses.

If  an  incident  did  occur,  it  could  have  a  material  effect  on  our  results  of 
operations,  financial  condition  or  cash  flows.  Furthermore,  the  non-
compliance or the occurrence of a serious incident at other nuclear facilities 
could result in increased regulation of the industry, which may increase NSP-
Minnesota’s compliance costs.

NSP-Wisconsin’s  production  and  transmission  system  is  operated  on  an 
integrated basis with NSP-Minnesota. NSP-Wisconsin may be subject to risks 
associated with NSP-Minnesota’s nuclear generation.

We  are  subject  to  commodity  risks  and  other  risks  associated  with 
energy markets and energy production.

If fuel costs increase, customer demand could decline and bad debt expense 
may rise, which could have a material impact on our results of operations. 
While we have fuel clause recovery mechanisms in most of our states, higher 
fuel costs could significantly impact our results of operations if costs are not 
recovered. Delays in the timing of the collection of fuel cost recoveries could 
impact our cash flows. Low fuel costs have a positive impact on sales, however 
low oil and natural gas prices could negatively impact oil and gas production 
activities and subsequently our sales volumes and revenue. 

A significant disruption in supply could cause us to seek alternative supply 
services at potentially higher costs or suffer increased liability for unfulfilled 
contractual obligations. Significantly higher energy or fuel costs relative to 
sales commitments have a negative impact on our cash flows and potentially 
result in economic losses. Potential market supply shortages may not be fully 
resolved through alternative supply sources and could cause disruptions in 
our ability to provide electric and/or natural gas services to our customers. 
Failure to provide service due to disruptions may also result in fines, penalties 
or cost disallowances through the regulatory process. 

We also engage in wholesale sales and purchases of electric capacity, energy 
and energy-related products as well as natural gas. In many markets, emission 
allowances and/or RECs are also needed to comply with various statutes and 
commission  rulings.  As  a  result  we  are  subject  to  market  supply  and 
commodity price risk. Commodity price changes can affect the value of our 
commodity trading derivatives. We mark certain derivatives to estimated fair 
market value on a daily basis. Actual settlements can vary significantly from 
estimated fair values recorded and significant changes from the assumptions 
underlying our fair value estimates could cause earnings variability.

Financial Risks

Our  profitability  depends  on  the  ability  of  our  utility  subsidiaries  to 
recover their costs and changes in regulation may impair the ability of 
our utility subsidiaries to recover costs from their customers.

We  are  subject  to  comprehensive  regulation  by  federal  and  state  utility 
regulatory agencies, including siting and construction of facilities, customer 
service and the rates that we can charge customers.

The profitability of our utility operations is dependent on our ability to recover 
the costs of providing energy and utility services and earn a return on our 
capital investment. Our rates are generally regulated and based on an analysis 
of the utility’s costs incurred in a test year. Our utility subsidiaries are subject 
to  both  future  and  historical  test  years  depending  upon  the  regulatory 
jurisdiction. Thus, the rates a utility is allowed to charge may or may not match 
its  costs  at  any  given  time.  Rate  regulation  is  premised  on  providing  an 
opportunity  to  earn  a  reasonable  rate  of  return  on  invested  capital.  In  a 
continued  low  interest  rate  environment  there  has  been  pressure  pushing 
down ROE. There can also be no assurance that our regulatory commissions 
will judge all the costs of our utility subsidiaries to be prudent, which could 
result in disallowances, or that the regulatory process will always result in 
rates  that  will  produce  full  recovery.  Changes  in  the  long-term  cost-
effectiveness or changes to the operating conditions of our assets may result 
in early retirements of utility facilities and while regulation typically provides 
relief for these types of changes, there is no assurance that regulators would 
allow full recovery of all remaining costs leaving all or a portion of these asset 
costs stranded. Higher than expected inflation or tariffs may increase costs 
of construction and operations. Rising fuel costs could increase the risk that 
our utility subsidiaries will not be able to fully recover their fuel costs from their 
customers.  Furthermore,  there  could  be  changes  in  the  regulatory 
environment that would impair the ability of our utility subsidiaries to recover 
costs historically collected from their customers, or these factors could cause 
the operating utilities to exceed commitments made regarding cost caps and 
result  in  less  than  full  recovery.  Overall,  management  currently  believes 
prudently  incurred  costs  are  recoverable  given  the  existing  regulatory 
mechanisms in place. 

Adverse regulatory rulings or the imposition of additional regulations could 
have an adverse impact on our results of operations and materially affect our 
ability  to  meet  our  financial  obligations,  including  debt  payments  and  the 
payment of dividends on our common stock.

18

Any reductions in our credit ratings could increase our financing costs 
and the cost of maintaining certain contractual relationships.

We cannot be assured that our current ratings or our subsidiaries’ ratings will 
remain in effect, or that a rating will not be lowered or withdrawn by a rating 
agency. Significant events including disallowance of costs, significantly lower 
returns on equity or equity ratios or impacts of tax policy changes may impact 
our cash flows and credit metrics, potentially resulting in a change in our credit 
ratings. In addition, our credit ratings may change as a result of the differing 
methodologies or change in the methodologies used by the various rating 
agencies.

Any downgrade could lead to higher borrowing costs and could impact our 
ability to access capital markets. Also, our utility subsidiaries may enter into 
contracts  that  require  the  posting  of  collateral  or  settlement  of  applicable 
contracts if credit ratings fall below investment grade.

We are subject to capital market and interest rate risks.

Utility  operations  require  significant  capital  investment.  As  a  result,  we 
frequently need to access capital markets. Any disruption in capital markets 
could have a material impact on our ability to fund our operations. Capital 
markets are global and impacted by issues and events throughout the world. 
Capital market disruption events and financial market distress could prevent 
us from issuing short-term commercial paper, issuing new securities or cause 
us to issue securities with unfavorable terms and conditions, such as higher 
interest rates.

Higher  interest  rates  on  short-term  borrowings  with  variable  interest  rates 
could also have an adverse effect on our operating results. Changes in interest 
rates  may  also  impact  the  fair  value  of  the  debt  securities  in  the  nuclear 
decommissioning and/or pension funds, as well as our ability to earn a return 
on short-term investments of excess cash.

We are subject to credit risks.

Credit risk includes the risk that our customers will not pay their bills, which 
may lead to a reduction in liquidity and an increase in bad debt expense. Credit 
risk  is  comprised  of  numerous  factors  including  the  price  of  products  and 
services provided, the overall economy and local economies in the geographic 
areas we serve, including local unemployment rates.

Credit risk also includes the risk that various counterparties that owe us money 
or product will become insolvent and/or breach their obligations. Should the 
counterparties  fail  to  perform,  we  may  be  forced  to  enter  into  alternative 
arrangements. In that event, our financial results could be adversely affected 
and incur losses.

We may at times have direct credit exposure in our short-term wholesale and 
commodity  trading  activity  to  financial  institutions  trading  for  their  own 
accounts or issuing collateral support on behalf of other counterparties. We 
may also have some indirect credit exposure due to participation in organized 
markets, such as CAISO, SPP, PJM, MISO and Electric Reliability Council of 
Texas, in which any credit losses are socialized to all market participants.

We have additional indirect credit exposures to financial institutions in the 
form of letters of credit provided as security by power suppliers under various 
purchased power contracts. If any of the credit ratings of the letter of credit 
issuers  were  to  drop  below  investment  grade,  the  supplier  would  need  to 
replace that security with an acceptable substitute. If the security were not 
replaced, the party could be in default under the contract.

Increasing costs of our defined benefit retirement plans and employee 
benefits  may  adversely  affect  our  results  of  operations,  financial 
condition or cash flows.

We have defined benefit pension and postretirement plans that cover most 
of our employees. Assumptions related to future costs, return on investments, 
interest rates and other actuarial assumptions have a significant impact on 
our funding requirements related to these plans. Estimates and assumptions 
may change. In addition, the Pension Protection Act changed the minimum 
funding requirements for defined benefit pension plans. Therefore, our funding 
requirements and related contributions may change in the future. Also, the 
payout of a significant percentage of pension plan liabilities in a single year 
due  to  high  retirements  or  employees  leaving  could  trigger  settlement 
accounting and could require Xcel Energy to recognize incremental pension 
expense related to unrecognized plan losses in the year liabilities are paid.

Increasing costs associated with health care plans may adversely affect 
our results of operations.

Our  self-insured  costs  of  health  care  benefits  for  eligible  employees  have 
increased in recent years. Increasing levels of large individual health care 
claims and overall health care claims could have an adverse impact on our 
results of operations, financial condition or cash flows. Changes in industry 
standards utilized in key assumptions (e.g., mortality tables) could have a 
significant impact on future liabilities and benefit costs. Legislation related to 
health care could also significantly change our benefit programs and costs.

We must rely on cash from our subsidiaries to make dividend payments.

We are a holding company and investments in our subsidiaries are our primary 
assets. Substantially all of our operations are conducted by our subsidiaries. 
Consequently, our operating cash flow and ability to service our debt and pay 
dividends depends upon the operating cash flows of our subsidiaries and their 
payment of dividends. Our subsidiaries are separate legal entities that have 
no obligation to pay any amounts due pursuant to our obligations or to make 
any funds available for dividends on our common stock. In addition, each 
subsidiary’s ability to pay dividends  depends on statutory and/or contractual 
restrictions which may include requirements to maintain minimum levels of 
equity  ratios,  working  capital  or  assets.  Also,  our  utility  subsidiaries  are 
regulated by state utility commissions, which possess broad powers to ensure 
that the needs of the utility customers are being met.

If our utility subsidiaries were to cease making dividend payments, our ability 
to  pay  dividends  on  our  common  stock  or  otherwise  meet  our  financial 
obligations could be adversely affected.

Federal tax law may significantly impact our business.

Xcel Energy’s utility subsidiaries collect through regulated rates estimated 
federal, state and local tax payments. Changes to federal tax law may benefit 
or  adversely  affect  our  earnings  and  customer  costs.  Changes  to  tax 
depreciable  lives  and  the  value  of  various  tax  credits  may  change  the 
economics of resources and our resource selections. There could be timing 
delays before regulated rates provide for realization of the tax changes in 
revenues.  In addition, certain  IRS tax  policies  such as the  requirement to 
utilize normalization may impact our ability to economically deliver certain 
types of resources relative to market prices. 

19

Macroeconomic Risks

Economic conditions impact our business.

Our  operations  are  affected  by  local,  national  and  worldwide  economic 
conditions.  Growth  in  customers  and  sales  are  correlated  with  economic 
conditions. 

Economic conditions may be impacted by insufficient financial sector liquidity 
leading to potential increased unemployment, which may impact customers’ 
ability  to  pay  timely,  increase  customer  bankruptcies,  and  may  lead  to 
additional bad debt expense. 

Further,  worldwide  economic  activity  impacts  the  demand  for  basic 
commodities necessary for utility infrastructure, which may impact our ability 
to acquire sufficient supplies. We operate in a capital intensive industry and 
federal policy on trade could significantly impact the cost of materials we use. 
We could be at risk for higher costs for materials and our workforce. There 
may be delays before these additional costs can be recovered in rates. 

Our operations could be impacted by war, acts of terrorism, and threats 
of terrorism or disruptions due to events.

Our  generation  plants,  fuel  storage  facilities,  transmission  and  distribution 
facilities  and  information  and  control  systems  may  be  targets  of  terrorist 
activities. Any disruption could impact operations or result in a decrease in 
revenues  and  additional  costs  to  repair  and  insure  our  assets.  These 
disruptions could have a material impact on our financial condition, results of 
operations  or  cash  flows.  The  potential  for  terrorism  has  subjected  our 
operations to increased risks and could have a material effect on our business. 
We  have  already  incurred  increased  costs  for  security  and  capital 
expenditures in response to these risks. 

The  insurance  industry  has  also  been  affected  by  these  events  and  the 
availability of insurance may decrease. In addition, insurance may have higher 
deductibles, higher premiums and more restrictive policy terms.

A disruption of the regional electric transmission grid, interstate natural gas 
pipeline  infrastructure  or  other  fuel  sources,  could  negatively  impact  our 
business,  our  brand  and  reputation.  Because  our  facilities  are  part  of  an 
interconnected system, we face the risk of possible loss of business due to a 
disruption caused by the actions of a neighboring utility or an event (e.g., 
severe  storm,  severe 
temperature  extremes,  wildfires,  generator  or 
transmission  facility  outage,  pipeline  rupture,  railroad  disruption,  operator 
error, sudden and significant increase or decrease in wind generation or a 
disruption of work force) within our operating systems or on a neighboring 
system. Any such disruption could result in a significant decrease in revenues 
and significant additional costs to repair assets, which could have a material 
impact on our results of operations, financial condition or cash flows.

A cyber incident or security breach could have a material effect on our 
business.

information 

We  operate  in  an  industry  that  requires  the  continued  operation  of 
technology,  control  systems  and  network 
sophisticated 
infrastructure. In addition, we use our systems and infrastructure to create, 
collect,  use,  disclose,  store,  dispose  of  and  otherwise  process  sensitive 
information,  including  company  data,  customer  energy  usage  data,  and 
personal information regarding customers, employees and their dependents, 
contractors, shareholders and other individuals.

Our  generation,  transmission,  distribution  and  fuel  storage  facilities, 
information technology systems and other infrastructure or physical assets, 
as well as information processed in our systems (e.g., information regarding 
our customers, employees, operations, infrastructure and assets) could be 
affected by cyber security incidents, including those caused by human error. 

20

Our industry has begun to see an increased volume and sophistication of 
cyber security incidents from international activist organizations, Nation States 
and individuals. Cyber security incidents could harm our businesses by limiting 
our  generating,  transmitting  and  distributing  capabilities,  delaying  our 
development and construction of new facilities or capital improvement projects 
to existing facilities, disrupting our customer operations or causing the release 
of customer information, all of which could expose us to liability. 

Our generation, transmission systems and natural gas pipelines are part of 
an interconnected system. Therefore, a disruption caused by the impact of a 
cyber security incident of the regional electric transmission grid, natural gas 
pipeline infrastructure or other fuel sources of our third party service providers’ 
operations, could also negatively impact our business. 

Our supply chain for procurement of digital equipment may expose software 
or hardware to these risks and could result in a breach or significant costs of 
remediation. In addition, such an event would likely receive federal and state 
regulatory scrutiny. We are unable to quantify the potential impact of cyber 
security threats or subsequent related actions. These potential cyber security 
incidents and regulatory action could result in a material decrease in revenues 
and may cause significant additional costs (e.g., penalties, third party claims, 
repairs,  insurance  or  compliance)  and  potentially  disrupt  our  supply  and 
markets for natural gas, oil and other fuels.

We maintain security measures to protect our information technology and 
control  systems,  network  infrastructure  and  other  assets.  However,  these 
assets and the information they process may be vulnerable to cyber security 
incidents, including the resulting disability, or failures of assets or unauthorized 
access to assets or information. If our technology systems or those of our 
third-party service providers were to fail or be breached, we may be unable 
to fulfill critical business functions. We are unable to quantify the potential 
impact  of  cyber  security  incidents  on  our  business,  our  brand,  and  our 
reputation. The cyber security threat is dynamic and evolves continually, and 
our  efforts  to  prioritize  network  monitoring  may  not  be  effective  given  the 
constant changes to threat vulnerability. 

Our operating results may fluctuate on a seasonal and quarterly basis 
and can be adversely affected by milder weather.

Our  electric  and  natural  gas  utility  businesses  are  seasonal  and  weather 
patterns can have a material impact on our operating performance. Demand 
for electricity is often greater in the summer and winter months associated 
with cooling and heating. Because natural gas is heavily used for residential 
and commercial heating, the demand depends heavily upon weather patterns. 
A significant amount of natural gas revenues are recognized in the first and 
fourth quarters related to the heating season. Accordingly, our operations have 
historically generated less revenues and income when weather conditions are 
milder in the winter and cooler in the summer. Unusually mild winters and 
summers could have an adverse effect on our financial condition, results of 
operations or cash flows.

Our operations use third party contractors in addition to employees to 
perform periodic and on-going work.

We rely on third party contractors to perform work for operations, maintenance 
and construction. We have contractual arrangements with these contractors 
which typically include performance standards, progress payments, insurance 
requirements and security for performance. 

Cyber  security  breaches  have  at  times  exploited  third  party  equipment  or 
software in order to gain access. Poor vendor performance could impact on 
going operations, restoration operations, our reputation and could introduce 
financial risk or risks of fines.

Public Policy Risks

We may be subject to legislative and regulatory responses to climate 
change, with which compliance could be difficult and costly.

Legislative  and  regulatory  responses  related  to  climate  change  and  new 
interpretations of existing laws create financial risk as our facilities may be 
subject to additional regulation at either the state or federal level in the future. 
Such regulations could impose substantial costs on our system.

We may be subject to climate change lawsuits. An adverse outcome could 
require substantial capital expenditures and could possibly require payment 
of  substantial  penalties  or  damages.  Defense  costs  associated  with  such 
litigation can also be significant. Such payments or expenditures could affect 
results of operations, financial condition or cash flows if such costs are not 
recovered through regulated rates.

Although the United States has not adopted any international or federal GHG 
emission reduction targets, many states and localities may continue to pursue 
climate policies in the absence of federal mandates. All of the steps that Xcel 
Energy  has  taken  to  date  to  reduce  GHG  emissions,  including  energy 
efficiency measures, adding renewable generation or retiring or converting 
coal plants to natural gas, occurred under state-endorsed resource plans, 
renewable energy standards and other state policies. While those actions 
likely  would  have  put  Xcel  Energy  in  a  good  position  to  meet  federal  or 
international standards being discussed, the lack of federal action does not 
adversely impact these state-endorsed actions and plans. 

If our regulators do not allow us to recover all or a part of the cost of capital 
investment or the O&M costs incurred to comply with the mandates, it could 
have a material effect on our results of operations, financial condition or cash 
flows.

Increased  risks  of  regulatory  penalties  could  negatively  impact  our 
business.

The Energy Act increased civil penalty authority for violation of FERC statutes, 
rules and orders.  The FERC can impose penalties of up to $1.3 million per 
violation per day, particularly as it relates to energy trading activities for both 
electricity and natural gas. In addition, NERC electric reliability standards and 
critical infrastructure protection requirements are mandatory and subject to 
potential financial penalties. Additionally, the PHMSA, Occupational Safety 
and Health Administration and other federal agencies have penalty authority.  
In the event of serious incidents, these agencies have become more active 
in pursuing penalties. Some states have the authority to impose substantial 
penalties. If a serious reliability or safety incident did occur, it could have a 
material effect on our results of operations, financial condition or cash flows. 

Environmental Risks

We  are  subject  to  environmental  laws  and  regulations,  with  which 
compliance could be difficult and costly.

We are subject to environmental laws and regulations that affect many aspects 
of  our  operations,  including  air  emissions,  water  quality,  wastewater 
discharges and the generation, transport and disposal of solid wastes and 
hazardous substances. Laws and regulations require us to obtain permits, 
licenses,  and  approvals  and  to  comply  with  a  variety  of  environmental 
requirements. 

Environmental laws and regulations can also require us to restrict or limit the 
output of facilities or the use of certain fuels, shift generation to lower-emitting, 
install pollution control equipment, clean up spills and other contamination 
and correct environmental hazards. Environmental regulations may also lead 
to shutdown of existing facilities. 

Failure to meet requirements of environmental mandates may result in fines 
or penalties. We may be required to pay all or a portion of the cost to remediate 
(i.e., clean-up) sites where our past activities, or the activities of other parties, 
caused environmental contamination. 

We  are  subject  to  mandates  to  provide  customers  with  clean  energy, 
renewable energy and energy conservation offerings. It could have a material 
effect  on  our  results  of  operations,  financial  condition  or  cash  flows  if  our 
regulators do not allow us to recover the cost of capital investment or the O&M 
costs incurred to comply with the requirements.

In addition, existing environmental laws or regulations may be revised and 
new  laws  or  regulations  may  be  adopted.  We  may  also  incur  additional 
unanticipated obligations or liabilities under existing environmental laws and 
regulations.

We are subject to physical and financial risks associated with climate 
change  and  other  weather,  natural  disaster  and  resource  depletion 
impacts.

Climate change can create physical and financial risk. Physical risks include 
changes in weather conditions and extreme weather events.

Our  customers’  energy  needs  vary  with  weather.  To  the  extent  weather 
conditions  are  affected  by  climate  change,  customers’  energy  use  could 
increase or decrease. Increased energy use due to weather changes may 
require  us  to  invest  in  generating  assets,  transmission  and  infrastructure. 
Decreased  energy  use  due  to  weather  changes  may  result  in  decreased 
revenues.  Extreme  weather  conditions  in  general  require  system  backup, 
costs,  and  can  contribute  to  increased  system  stress,  including  service 
interruptions. Extreme weather conditions creating high energy demand may 
raise  electricity  prices,  increasing  the  cost  of  energy  we  provide  to  our 
customers.

Severe weather impacts our service territories, primarily when thunderstorms, 
flooding, tornadoes, wildfires and snow or ice storms occur. To the extent the 
frequency of extreme weather events increases, this could increase our cost 
of providing service. Periods of extreme temperatures could impact our ability 
to  meet  demand.  Changes  in  precipitation  resulting  in  droughts  or  water 
shortages  could  adversely  affect  our  operations.  Drought  conditions  also 
contribute to the increase in wildfire risk from our electric generation facilities. 
While we carry liability insurance, given an extreme event, if Xcel Energy was 
found to be liable for wildfire damages, amounts that potentially exceed our 
coverage could negatively impact our results of operations, financial condition 
or cash flows. Drought or water depletion could adversely impact our ability 
to provide electricity to customers and increase the price paid for energy. We 
may not recover all costs related to mitigating these physical and financial 
risks. 

Climate change may impact a region’s economy, which could impact our sales 
and revenues. The price of energy has an impact on the economic health of 
our  communities. The  cost  of  additional  regulatory  requirements,  such  as 
regulation of GHG, could impact the availability of goods and prices charged 
by our suppliers which would normally be borne by consumers through higher 
prices for energy and purchased goods. To the extent financial markets view 
climate change and emissions of GHGs as a financial risk, this could negatively 
affect our ability to access capital markets or cause us to receive less than 
ideal terms and conditions.

Item 3 — Legal Proceedings

Xcel Energy is involved in various litigation matters that are being defended 
and handled in the ordinary course of business. Assessment of whether a loss 
is probable or is a reasonable possibility, and whether a loss or a range of 
loss is estimable, often involves a series of complex judgments regarding 
future events. Management maintains accruals for losses that are probable 
of being incurred and subject to reasonable estimation. Management may be 
unable to estimate an amount or range of a reasonably possible loss in certain 
situations,  including  but  not  limited  to,  when  (1)  damages  sought  are 
indeterminate, (2) proceedings are in the early stages or (3) matters involve 
novel  or  unsettled  legal  theories.  In  such  cases,  there  is  considerable 
uncertainty  regarding  the  timing  or  ultimate  resolution  of  such  matters, 
including a possible eventual loss.

Item 7 — Management’s Discussion and Analysis of Financial 
Condition and Results of Operations

Successful execution of our strategic objectives should allow Xcel Energy to 
continue to deliver a competitive total return for our shareholders.

Business Segments and Organizational Overview

Lead the clean energy transition

Xcel Energy Inc. is a public utility holding company. Xcel Energy’s operations 
include the activity of four utility subsidiaries that serve electric and natural 
gas  customers  in  eight  states. The  utility  subsidiaries  serve  customers  in 
portions of Colorado, Michigan, Minnesota, New Mexico, North Dakota, South 
Dakota, Texas and Wisconsin. Along with the utility subsidiaries, the TransCo 
subsidiaries, WYCO (a joint venture formed with CIG to develop and lease 
natural  gas  pipelines,  storage  and  compression  facilities)  and  WGI  (an 
interstate  natural  gas  pipeline  company)  comprise  the  regulated  utility 
operations.

Xcel  Energy  Inc.’s  immaterial  nonregulated  subsidiaries  are  Eloigne  and 
Capital Services. 

Management’s Strategic Priorities

Xcel Energy’s vision is to be the preferred and trusted provider of the energy 
our customers need. We strive to provide our investors an attractive value 
proposition and our customers with safe, clean and reliable energy services 
at a competitive price. This mission is enabled via three key strategic priorities:

• 

• 

• 

Lead the clean energy transition;

Enhance the customer experience; and,

Keep bills low.

For more than a decade, we have managed the risk of climate change and 
increasing customer demand for renewable energy through a clean energy 
strategy  that  consistently  reduces  carbon  emissions  and  transitions  our 
operations for the future. As a result, we have successfully reduced our carbon 
emissions to our customers by approximately 40% from 2005 to 2018. We 
expect to reduce our carbon footprint by 80% by 2030 (over 2005 levels). We 
have also announced our vision to serve all customers with 100% zero-carbon 
emissions by 2050. 

Our service territories benefit from the geographic concentration of favorable 
renewable  resources.    Strong  wind  and  high  solar  irradiance  yield  high 
generation capacity factors, which lowers the cost of these resources. The 
combination  of  high  capacity  factors,  grid  options  from  transmission 
investment  and  market  operations,  improved  supply  chain,  technological 
improvements and the extension of the renewable tax credits translates into 
low renewable energy costs for our customers. As a result, we are able to 
invest  in  renewable  generation,  in  which  the  capital  costs  are  largely  or 
completely offset by fuel savings. This provides us the opportunity to lower 
the emission profile of our generation fleet, grow our renewable portfolio and 
provide significant fuel savings to our customers. We call this our “Steel for 
Fuel” strategy.

24

 
We are transitioning how we produce, deliver and encourage the efficient use 
of energy through four primary mechanisms:

Provide  a  competitive  total  return  to  investors  and  maintain  strong 
investment grade credit rating 

Increasing the use of affordable renewable energy;

Offering energy efficiency programs for customers;

Through our disciplined approach to business growth, financial investment, 
operations and safety, we plan to:

• 

• 

• 

• 

Retiring or repowering coals units and modernizing our generating plants; 
and,

Advancing power grid capabilities.

• 

• 

• 

We have announced ambitious plans to add approximately 3,600 MW of wind 
energy on our system by 2021.

In addition, the proposed CEP in Colorado encompasses the retirement of 
660 MW from two coal-fired units at Comanche and the addition of up to 1,100 
MW of wind, 700 MW of solar and 275 MW of battery storage.

Enhance the customer experience

The  utility  landscape  is  changing,  and  we  must  continue  to  thoughtfully 
anticipate and address the future needs of our stakeholders, including our 
customers,  policymakers,  employees  and  shareholders.  Our  customers 
expect  to  have  choices,  and  we  are  committed  to  providing  options  and 
solutions that they want and value at a competitive price. 

We will continue to expand our production of renewable energy, including wind 
and solar alternatives, and further develop and promote DSM, conservation 
and  renewable  programs.  We  are  also  in  the  process  of  transforming  our 
transmission and distribution systems to accommodate increased levels of 
renewables, distributed energy resources and corresponding data growth, 
while maintaining high levels of reliability and security and keeping customer 
bills affordable. We also are expanding our Renewable*Connect program, 
which  allows  customers  to choose  how  much of  their  energy comes  from 
renewable  sources.  Renewable*Connect  has  regulatory  approval 
in 
Minnesota, Colorado and Wisconsin. This is yet another way for us to add 
renewable  energy  and  meet  the  needs  of  our  customers.  Importantly, 
Renewable*Connect does not negatively impact the bills of non-participants. 
Finally, we are improving our communications to enable customers to interact 
with us in the way they prefer.

Keep bills low

Xcel Energy is very focused on our customers and the impact our actions 
have on their bill. Our objective is to keep total bill increases at or below the 
rate of inflation so our prices remain competitive relative to alternatives. We 
expect to continue to keep our customer bills low by executing on our Steel 
for  Fuel  plan,  controlling  O&M  costs  and  promoting  energy  efficiency  and 
conservation.

Xcel Energy is working to keep long-term O&M expense relatively consistent 
without  compromising  reliability  or  safety.  We  intend  to  accomplish  this 
objective  by  continually  improving  our  processes,  leveraging  technology, 
proactively managing risk and maintaining a workforce that is prepared to 
meet the needs of our business today and tomorrow. In 2018, we experienced 
warmer than normal summer weather, which caused us to spend additional 
O&M for vegetation management and system maintenance due to the hot 
summer,  business  systems  costs,  investments  to  improve  and  enhance 
business processes and customer service, as well as damage prevention and 
remediation costs. However, we remain committed to our long-term objective 
of improving operating efficiencies and taking costs out of the business for 
the benefit of our customers and anticipate that our long-term O&M expense 
trend will remain relatively consistent.

Deliver long-term annual EPS growth of 5% to 7%;

Deliver annual dividend increases of 5% to 7%;

Target a dividend payout ratio of 60% to 70% of annual ongoing EPS; 
and,

•  Maintain senior secured debt credit ratings in the A range and senior 

unsecured debt credit ratings in the BBB+ to A range.

We have consistently achieved our financial objectives, meeting or exceeding 
our earnings guidance range for fourteen consecutive years, and we believe 
we are positioned to continue to deliver on our value proposition. Our ongoing 
earnings  have  grown  approximately  6.1%  and  our  dividend  has  grown 
approximately 4.5% annually from 2005 - 2018. In addition, our current senior 
unsecured debt credit ratings for Xcel Energy and its utility subsidiaries are 
in the BBB+ to A range, while our secured operating company debt ratings 
are in the A range. 

Non-GAAP Financial Measures

financial 

includes 

following  discussion 

information  prepared 

in 
The 
accordance with GAAP, as well as certain non-GAAP financial measures such 
as the ongoing return on equity (ROE), electric margin, natural gas margin, 
ongoing earnings and ongoing diluted EPS. Generally, a non-GAAP financial 
measure is a measure of a company’s financial performance, financial position 
or  cash  flows  that  excludes  (or  includes)  amounts  that  are  adjusted  from 
measures calculated and presented in accordance with GAAP. Xcel Energy’s 
management uses non-GAAP measures for financial planning and analysis, 
for reporting of results to the Board of Directors, in determining performance-
based compensation, and communicating its earnings outlook to analysts and 
investors.  Non-GAAP  financial  measures  are  intended  to  supplement 
investors’ understanding of our performance and should not be considered 
alternatives for financial measures presented in accordance with GAAP. These 
measures are discussed in more detail below and may not be comparable to 
other companies’ similarly titled non-GAAP financial measures.

Ongoing ROE

Ongoing ROE is calculated by dividing the net income or loss of Xcel Energy 
or each subsidiary, adjusted for certain nonrecurring items, by each entity’s 
average stockholder’s equity. We use these non-GAAP financial measures to 
evaluate and provide details of earnings results.

Electric and Natural Gas Margins

Electric  margin  is  presented  as  electric  revenues  less  electric  fuel  and 
purchased power expenses. Natural gas margin is presented as natural gas 
revenues less the cost of natural gas sold and transported. Expenses incurred 
for electric fuel and purchased power and the cost of natural gas are generally 
recovered  through  various  regulatory  recovery  mechanisms. As  a  result, 
changes in these expenses are generally offset in operating revenues. 

Management  believes  electric  and  natural  gas  margins  provide  the  most 
meaningful  basis  for  evaluating  our  operations  because  they  exclude  the 
revenue  impact  of  fluctuations  in  these  expenses. These  margins  can  be 
reconciled to operating income, a GAAP measure, by including other operating 
revenues,  cost  of  sales-other,  O&M  expenses,  conservation  and  DSM 
expenses, depreciation and amortization and taxes (other than income taxes).

Earnings Adjusted for Certain Items (Ongoing Earnings and Ongoing 
Diluted EPS)

Earnings Adjusted for Certain Items

2018 Comparison with 2017

GAAP diluted EPS reflects the potential dilution that could occur if securities 
or other agreements to issue common stock (i.e., common stock equivalents) 
were  settled.  The  weighted  average  number  of  potentially  dilutive  shares 
outstanding used to calculate Xcel Energy Inc.’s diluted EPS is calculated 
using the treasury stock method. Ongoing earnings reflect adjustments to 
GAAP  earnings  (net  income)  for  certain  items.  Ongoing  diluted  EPS  is 
calculated by dividing the net income or loss of each subsidiary, adjusted for 
certain items, by the weighted average fully diluted Xcel Energy Inc. common 
shares outstanding for the period. Ongoing diluted EPS for each subsidiary 
is calculated by dividing the net income or loss of such subsidiary, adjusted 
for  certain  items,  by  the  weighted  average  fully  diluted  Xcel  Energy  Inc. 
common shares outstanding for the period.

We use these non-GAAP financial measures to evaluate and provide details 
of Xcel Energy’s core earnings and underlying performance. We believe these 
measurements are useful to investors to evaluate the actual and projected 
financial performance and contribution of our subsidiaries. For the year ended 
Dec. 31, 2017, Xcel Energy recognized an estimated one-time, non-cash, 
income tax expense of approximately $23 million for net excess deferred tax 
assets  which  may  not  be  recovered  from  customers  or  not  attributable  to 
regulated  operations,  increased  valuation  allowances,  etc.  due  to  the 
enactment of the TCJA in December 2017. For the year ended Dec. 31, 2018, 
there  were  no  such  adjustments  to  GAAP  earnings  and  therefore  GAAP 
earnings equal ongoing earnings. 

See Note 7 to the consolidated financial statements for further information.

Xcel  Energy’s  management  believes 
that  ongoing  earnings  reflects 
management’s  performance  in  operating  the  company  and  provides  a 
meaningful representation of the performance of Xcel Energy’s core business. 
In addition, Xcel Energy’s management uses ongoing earnings internally for 
financial planning and analysis, reporting results to the Board of Directors and 
when communicating its earnings outlook to analysts and investors.

2017 Adjustment to GAAP Earnings — Impact of the TCJA — Xcel Energy 
recognized  an  estimated  one-time,  non-cash,  income  tax  expense  of 
approximately $23 million in the fourth quarter of 2017 for net excess deferred 
tax assets which may not be recovered from customers or not attributable to 
regulated  operations,  increased  valuation  allowances,  etc.  due  to  the 
enactment  of  the  TCJA  in  December  2017.  The  income  tax  expense 
associated with the TCJA enactment has been excluded from Xcel Energy’s 
2017 ongoing earnings, given the non-recurring nature of the TCJA’s broad 
and sweeping reform of the IRC. 

See Note 7 to the consolidated financial statements for further information.

Differences between GAAP and ongoing earnings are due to the non-recurring 
impact of the TCJA experienced in 2017. Explanations for operating company 
results below exclude the offsetting impacts of the TCJA on sales, depreciation 
and amortization expense and income tax.

Xcel Energy — GAAP and ongoing earnings increased $0.22 and $0.17 per 
share,  respectively.  Earnings  increased  as  a  result  of  higher  electric  and 
natural gas revenues primarily due to favorable weather and sales growth and 
higher AFUDC. These positive factors were partially offset by increased O&M, 
depreciation and interest expenses. GAAP earnings for 2017 include the non-
recurring negative impact of the TCJA.

2018 Ongoing Diluted EPS

PSCo 41%

SPS 16%

NSP–Minnesota 36%

NSP–Wisconsin 7%

PSCo — GAAP and ongoing 2018 earnings increased $0.11 and $0.14 per 
share,  respectively.  Increases  were  driven  by  higher  natural  gas  margins 
largely due to a natural gas rate increase, higher electric margins reflecting 
favorable weather and sales growth, and additional AFUDC associated with 
the Rush Creek wind project. These items were partially offset by higher O&M 
expenses, interest charges, depreciation expense and property taxes.

NSP-Minnesota — 2018 GAAP earnings were consistent with 2017, while 
2018 ongoing earnings decreased $0.05 per share. The decrease in ongoing 
earnings reflects higher depreciation expense and O&M expenses. These 
amounts  were  partially  offset  by  higher  electric  and  natural  gas  margins 
attributable to favorable weather. 

SPS — 2018 GAAP and ongoing earnings increased $0.11 and $0.12 per 
share, respectively. Increases were primarily due to higher electric margins 
reflecting favorable weather and sales growth and a rate increase in New 
Mexico, AFUDC related to the Hale County wind project and lower interest 
charges. Increases were partially offset by higher depreciation expense.

26

NSP-Wisconsin — 2018 GAAP and ongoing earnings increased $0.03 per 
share. Increases reflect higher electric and natural gas rates and the impact 
of favorable weather and sales growth, which were partially offset by higher 
depreciation.

Xcel Energy Inc. and other — Xcel Energy Inc. and other primarily includes 
financing costs at the holding company. 2018 GAAP earnings were consistent 
with 2017, while 2018 ongoing earnings decreased $0.07 per share. Decrease 
was primarily due to higher interest expense related to additional debt and 
the change in the federal income tax rate.

2017 Comparison with 2016

Xcel Energy — GAAP earnings increased $0.04 per share for 2017. Ongoing 
earnings  increased  $0.09  per  share,  excluding  the  impact  of  the  TCJA. 
Earnings were higher as a result of increased electric and natural gas margins 
to recover infrastructure investments, reduced O&M expenses, a lower ETR 
and higher AFUDC. These positive factors were partially offset by increased 
depreciation expense, interest charges and property taxes.

PSCo  —  GAAP  earnings  increased  $0.06  per  share  for  2017.  Ongoing 
earnings increased $0.03 per share, excluding the impact of the TCJA. The 
increase in earnings was driven by higher electric and natural gas margins, 
increased AFUDC primarily related to the Rush Creek wind project, a decrease 
in O&M expenses (timing of generation outages) and a lower ETR, partially 
offset  by  higher  depreciation  expense,  interest  charges  and  the  impact  of 
unfavorable weather.

NSP-Minnesota  —  GAAP  earnings  were  flat  for  2017.  Ongoing  earnings 
increased $0.05 per share, excluding the impact of the TCJA. The change 
reflects higher electric margins driven by a 2017 Minnesota rate increase as 
well as increased gas margins, a lower ETR and reduced O&M expenses. 
These positive factors were partially offset by higher depreciation expense 
due  to  increased  invested  capital  as  well  as  prior  year  amortization  of 
Minnesota’s excess depreciation reserve and higher property taxes.

SPS — GAAP earnings increased $0.01 per share for 2017. Ongoing earnings 
were flat, excluding the impact of the TCJA. Rate increases in Texas and New 
Mexico  and  a  lower  ETR  were  offset  by  higher  depreciation  expense 
(representing continued investment), O&M expenses (including the prior year 
deferrals associated with the Texas 2016 rate case), property taxes and the 
impact of unfavorable weather.

NSP-Wisconsin — GAAP and ongoing earnings increased $0.02 per share 
for 2017. The change in ongoing earnings was driven by a rise in electric and 
natural gas rates, partially offset by additional depreciation expense related 
to  continued  transmission  and  distribution  investments  and  higher  O&M 
expenses.

Equity  earnings  of  unconsolidated  subsidiaries  —  GAAP  earnings 
increased  $0.02  per  share  for  2017.  Ongoing  earnings  of  unconsolidated 
subsidiaries decreased $0.02 per share, excluding the impact of the TCJA. 
The decline primarily related to lower revenues due to lower rates at WYCO.

Degree-day or THI data is used to estimate amounts of energy required to 
maintain comfortable indoor temperature levels based on each day’s average 
temperature and humidity. HDD is the measure of the variation in the weather 
based on the extent to which the average daily temperature falls below 65° 
Fahrenheit. CDD is the measure of the variation in the weather based on the 
extent to which the average daily temperature rises above 65° Fahrenheit. 
Each degree of temperature above 65° Fahrenheit is counted as one CDD, 
and each degree of temperature below 65° Fahrenheit is counted as one 
HDD. In Xcel Energy’s more humid service territories, a THI is used in place 
of CDD, which adds a humidity factor to CDD. HDD, CDD and THI are most 
likely  to  impact  the  usage  of  Xcel  Energy’s  residential  and  commercial 
customers. Industrial customers are less sensitive to weather.

Normal  weather  conditions  are  defined  as  either  the  20-year  or  30-year 
average of actual historical weather conditions. The historical period of time 
used in the calculation of normal weather differs by jurisdiction, based on 
regulatory practice. To calculate the impact of weather on demand, a demand 
factor is applied to the weather impact on sales. Extreme weather variations, 
windchill  and  cloud  cover  may  not  be  reflected  in  weather-normalized 
estimates. Percentage increase (decrease) in normal and actual HDD, CDD

The following summarizes the items that affected the individual revenue and 
expense items reported in the consolidated statements of income.

Estimated Impact of Temperature Changes on Earnings — Unusually hot 
summers or cold winters increase electric and natural gas sales, while mild 
weather  reduces  electric  and  natural  gas  sales.  The  estimated  impact  of 
weather  on  earnings  is  based  on  the  number  of  customers,  temperature 
variances and the amount of natural gas or electricity historically used per 
degree of temperature. Weather deviations from normal levels can affect Xcel 
Energy’s financial performance.

approximately 0.3% for retail electric and 0.5% for firm natural gas for the twelve months 
ended.

•

• 

PSCo’s  decline  in  residential  sales  reflects  lower  use  per  customer, 
partially offset by customer additions. C&I growth was mainly due to an 
increase  in  customers  and  higher  use  for  large  C&I  customers  that 
support the mining, oil and natural gas industries, partially offset by lower 
use for the small C&I class.

NSP-Minnesota’s residential sales decrease was a result of lower use 
per customer, partially offset by customer growth. The decline in C&I 
sales was largely due to reduced usage, which offset an increase in the 
number of customers. Declines in services more than offset increased 
sales to large customers in manufacturing and energy industries.

SPS’ residential sales fell largely due to lower use per customer. The 
increase in C&I sales reflects customer additions and greater use for 
large C&I customers driven by the oil and natural gas industry in the 
Permian Basin.

NSP-Wisconsin’s residential sales increase was primarily attributable to 
higher use per customer and customer additions. C&I growth was largely 
due to higher use per customer and increased sales to customers in the 
sand  mining  industry  and  large  customers  in  the  energy  and 
manufacturing industries.

Weather-normalized 2017 Natural Gas Sales Growth

• 

Higher natural gas sales reflect an increase in the number of customers, 
partially offset by a decline in customer use.

Weather-normalized sales for 2019 are projected to be relatively consistent 
with 2018 levels for retail electric customers and within a range of 0.0% to 
1.0% over 2018 levels for retail natural gas customers.

Electric Margin

Natural Gas Margin

Electric revenues and fuel and purchased power expenses are impacted by 
fluctuations in the price of natural gas, coal and uranium used in the generation 
of electricity. However, these price fluctuations have minimal impact on electric 
margin due to fuel recovery mechanisms that recover fuel expenses. Electric 
margin was reduced by approximately $105 million in 2018 and $130 million 
in 2017 for PTCs (grossed up for federal income tax) which were returned to 
customers.  Margin  reductions  for  PTCs  are  largely  offset  by  income  tax 
benefits.

Nuclear plant operations and amortization expenses are lower mostly 
due to reduced refueling outage costs and operating efficiencies.

Plant  generation  costs  decreased  as  a  result  of  lower  expenses 
associated  with  planned  outages  and  overhauls  at  a  number  of 
generation facilities.

Employee  benefits  expense  includes  the  recognition  of  an  $8  million 
pension settlement expense in the fourth quarter of 2017.

Conservation  and  DSM  Program  Expenses  —  Conservation  and  DSM 
program expenses increased $17 million, or 6.2%, for 2018. The increase 
was primarily due to recovery for conservation programs to assist customers 
in  reducing  energy  use.  Conservation  and  DSM  expenses  are  generally 
recovered concurrently through riders and base rates. Timing of recovery may 
vary from when costs are incurred.

Conservation and DSM program expenses increased $28 million, or 11.4%, 
for  2017  compared  with  2016.  The  increase  was  due  to  higher  customer 
participation in electric conservation programs and recovery rates, mostly in 
Minnesota.

Depreciation and Amortization — Depreciation and amortization increased 
$163 million, or 11%, for 2018. The increase was primarily driven by capital 
investments  and  additional  amortization  of  a  prepaid  pension  asset  in 
Colorado (approximately $75 million) related to TCJA settlements, which were 
offset by lower income taxes. 

Depreciation  and  amortization  increased  $176  million,  or  13.5%,  for  2017 
compared with 2016. The increase was primarily due to capital investments 
and prior year amortization of the excess depreciation reserve in Minnesota.

Interest charges increased $16 million, or 2.5%, for 2017 compared with 2016. 
The increase was related to higher debt levels to fund capital investments, 
partially offset by refinancings at lower interest rates.

Income Taxes — Income tax expense decreased $361 million for 2018. The 
decrease was primarily driven by a lower federal tax rate due to the TCJA, 
lower pretax earnings, a one time, non-cash income tax expense related to 
the TCJA in 2017, an increase in plant-related regulatory differences related 
to ARAM  (net  of  deferrals),  2018  non-plant  excess  accumulated  deferred 
income tax amortization, and the impact of 2018 investment tax credits. These 
were partially offset by a higher tax benefit for the resolution of past appeals/
audits in 2017 and a higher tax benefit for adjustments in 2017. The ETR was 
12.6% for 2018 compared with 32.1% for 2017. The lower ETR in 2018 was 
largely due to the adjustments above. 

Income tax expense decreased $39 million for 2017 compared with 2016. The 
decrease  was  primarily  driven  by  increased  wind  PTCs,  a  net  tax  benefit 
related to the resolution of appeals/audits in 2017, an increase in R&E credits, 
lower  pretax  earnings  in  2017  and  a  rise  in  permanent  plant-related 
adjustments. PTCs are flowed back to customers and reduce electric margin. 
The decrease was partially offset by the estimated one-time, non-cash, income 
tax expense recognized in the fourth quarter related to the TCJA. The ETR 
was 32.1% for 2017 compared with 34.1% for 2016. The lower ETR in 2017 
was primarily due to the adjustments referenced above. Excluding the impact 
for the TCJA adjustment, the ETR would have been 30.7% for 2017.

Factors Affecting Results of Operations

Xcel Energy’s utility revenues depend on customer usage, which varies with 
weather  conditions,  general  business  conditions  and  the  cost  of  energy 
services.  Various  regulatory  agencies  approve  the  prices  for  electric  and 
natural gas service within their respective jurisdictions and affect Xcel Energy’s 
ability to recover its costs from customers. Historical and future trends of Xcel 
Energy’s operating results have been, and are expected to be, affected by a 
number of factors, including those listed below.

31

Regulation

FERC and State Regulation — The FERC and various state and local regulatory commissions regulate Xcel Energy Inc.’s utility subsidiaries and WGI. The 
electric and natural gas rates charged to customers of Xcel Energy Inc.’s utility subsidiaries and WGI are approved by the FERC or the regulatory commissions 
in the states in which they operate. The rates are designed to recover plant investment, operating costs and an allowed return on investment. Xcel Energy 
Inc.’s utility subsidiaries request changes in rates for utility services through filings with governing commissions. Changes in operating costs can affect Xcel 
Energy’s financial results, depending on the timing of rate case filings and implementation of final rates. Other factors affecting rate filings are new investments, 
sales, conservation and DSM efforts, and the cost of capital. In addition, the regulatory commissions authorize the ROE, capital structure and depreciation 
rates in rate proceedings. Decisions by these regulators can significantly impact Xcel Energy’s results of operations.

Tax Reform — Regulatory Proceedings

In December 2017, the TCJA was signed into law, enacting significant changes to the IRC, including a reduction of the corporate income tax rate from 35% to 
21% and a resulting reduction in deferred tax assets and liabilities. As a result of IRS requirements and past regulatory treatment of income taxes in the 
determination of regulated rates, the impacts of TCJA are primarily recognized as a regulatory liability. Treatment of these tax benefits, (e.g., degree to which 
benefits will be used to refund currently effective rates and/or used to mitigate other costs and potential future rate increases) is subject to regulatory approval.

South Dakota — In July 2018, the SDPUC approved a settlement providing a one-time customer refund 
of $11 million for the 2018 impact of the TCJA, while NSP-Minnesota would retain the TCJA benefits in 
2019 and 2020 in exchange for a two-year rate case moratorium.

North Dakota — In November 2018, the NDPSC approved a TCJA settlement in which NSP-Minnesota 
will amortize $1 million annually of the regulatory asset for the remediation of the MGP site in Fargo, ND 
and retain the TCJA savings to offset the MGP amortization expense.

North Dakota — In February 2019, the NDPSC approved a settlement including a one-time customer 
refund of $10 million for 2018, while NSP-Minnesota would retain the TCJA benefits in 2019 and 2020 in 
exchange for a two-year rate case moratorium. 

Wisconsin — In May 2018, the PSCW approved customer refunds of $27 million and deferrals of 
approximately $5 million until NSP-Wisconsin’s next rate case proceeding.

Michigan — In May 2018, the MPSC approved electric and natural gas TCJA settlement agreements. 
Most of the electric TCJA benefits were reflected in NSP-Wisconsin’s approved Michigan 2018 electric 
base rate case.

In February 2018, the ALJ recommended approval of a TCJA settlement agreement, which included a $20 
million reduction to PSCo’s provisional rates effective March 1, 2018. In September 2018, PSCo revised 
its 2018 TCJA benefit estimate to $24 million and requested an equity ratio of 56% to offset the negative 
impact of the TCJA on credit metrics. In December 2018, the CPUC approved an equity ratio of 54.6% and 
utilized the remainder of the TCJA benefit to reduce an existing prepaid pension asset. The CPUC also 
ordered 2018 excess non-plant ADIT benefits of $11.1 million be utilized to accelerate amortization of the 
prepaid pension asset.

In 2018, the CPUC approved a TCJA settlement agreement that included a customer refund of $42 million 
in 2018, with the remainder of the $59 million of TCJA benefits to be used to accelerate the amortization 
of an existing prepaid pension asset. For 2019, the expected customer refund is estimated to be $67 million, 
and amortization of the prepaid pension asset is estimated to be $34 million. Impacts of the TCJA for 2020 
and future years are expected to be addressed in a future electric rate case.

Texas -  In December 2018, the PUCT approved a rate settlement which fully reflects the TCJA cost impacts 
and results in no change in customer rates or refunds and SPS’ actual capital structure, which SPS has 
informed the parties it intends to be up to a 57% equity ratio to offset the negative impacts on its credit 
metrics and potentially its credit ratings. 

New Mexico - In September 2018, the NMPRC issued its final order in SPS’ 2017 electric rate case, which 
included a $10 million refund of the 2018 impact of the TCJA. SPS subsequently filed an appeal with the 
NMSC, including the order to refund retroactive TCJA savings. The NMSC granted a temporary stay to 
delay the implementation of the retroactive TCJA refund until a decision on the appeal occurs.

On Feb. 15, 2019, SPS and the NMPRC filed a Joint Motion to Dismiss with the NMSC, requesting they 
remand  the  case  back  to  the  NMPRC  to  provide  them  the  opportunity  to  revise  its  rate  case  order  in 
accordance with the motion. This would require the NMPRC to replace the order issued in September 2018 
and eliminate the retroactive TCJA refund. The revised order would be subject to further administrative or 
judicial review.

associated with the TCJA impacts (retroactive Jan. 1, 2018 - Sept. 27, 2018). SPS recorded a regulatory 
liability for this amount in the third quarter of 2018. SPS subsequently filed an appeal of the order. The 
NMSC subsequently granted a temporary stay to delay the implementation of the retroactive TCJA refund 
until a decision on the appeal occurs.

On Feb. 15, 2019, SPS and the NMPRC filed a Joint Motion to Dismiss with the NMSC, requesting they 
remand  the  case  back  to  the  NMPRC  to  provide  them  the  opportunity  to  revise  its  rate  case  order  in 
accordance with the motion. This would require the NMPRC to replace the order issued in September 2018

NSP-Minnesota — Mankato Energy Center Acquisition — In November 
2018, NSP-Minnesota reached an agreement with Southern Power Company 
to purchase the 760 MW natural gas combined cycle Mankato Energy Center 
for  approximately  $650  million.  NSP-Minnesota  previously  contracted  to 
purchase the energy and capacity of this facility through a PPA. The asset 
acquisition  is  anticipated  to  close  in  mid-2019  and  subject  to  regulatory 
approvals  from  the  MPUC,  NDPSC,  FERC  and  DOJ.  The  acquisition  is 
projected to provide net customer savings of approximately $50 million to 
$150 million over the life of the plant.

NSP-Minnesota — Wind Repowering Acquisition — In December 2018, 
NSP-Minnesota filed with the MPUC to acquire the Jeffers and Community 
Wind  North  wind  farms  from  Longroad  Energy.  The  wind  farms  will  have 
approximately 70 MW of capacity after being repowered. The repowering is 
expected to be completed by December 2020 to qualify for the 100% PTC 
benefit.  The  acquisition  is  projected  to  provide  customer  savings  of 
approximately $7 million over the life of the wind farms. Cost of acquisition is 
approximately $135 million and pending MPUC approval. 

General Economic Conditions

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Economic conditions may have a material impact on Xcel Energy’s operating 
results. Other events impact overall economic conditions and management 
cannot predict the impact of fluctuating energy prices, terrorist activity, war or 
the threat of war. However, Xcel Energy could experience a material impact 
to its results of operations, future growth or ability to raise capital resulting 
from  a  sustained  general  slowdown  in  economic  growth  or  a  significant 
increase in interest rates.

Fuel Supply and Costs

See Item 1 — Fuel Supply and Costs for discussion of fuel supply and costs.

Pension Plan Costs and Assumptions

Xcel Energy has significant net pension and postretirement benefit costs that 
are measured using actuarial valuations. Key assumptions in these valuations 
include  discount  rates  and  expected  return  on  plan  assets.    Xcel  Energy 
evaluates these key assumptions at least annually by analyzing current market 
conditions,  which  include  changes  in  interest  rates  and  market  returns. 
Changes in the related net pension and postretirement benefits costs and 
funding requirements may occur in the future due to changes in assumptions. 
The payout of a significant percentage of pension plan liabilities in a single 
year due to high retirements or employees leaving Xcel Energy would trigger 
settlement accounting and could require Xcel Energy to recognize material 
incremental pension expense related to unrecognized plan losses in the year 
these liabilities are paid. For further discussion and a sensitivity analysis on 
these  assumptions,  see  “Employee  Benefits”  under  Critical  Accounting 
Policies and Estimates.

Environmental Matters

Environmental costs include accruals for nuclear plant decommissioning and 
payments for storage of spent nuclear fuel, disposal of hazardous materials 
and waste, remediation of contaminated sites, monitoring of discharges to the 
environment and compliance with laws and permits with respect to emissions.

Costs charged to operating expenses for nuclear decommissioning and spent 
nuclear  fuel  disposal  expenses,  environmental  monitoring  and  disposal  of 
hazardous materials and waste were approximately:

• 

• 

• 

$309 million in 2018;

$303 million in 2017; and,

$304 million in 2016.

Xcel Energy estimates an average annual expense of approximately $356 
million from 2019 - 2023 for similar costs. The precise timing and amount of 
environmental  costs,  including  those  for  site  remediation  and  disposal  of 
hazardous  materials,  are  unknown.  Additionally,  the  extent  to  which 
environmental  costs  will  be  included  in  and  recovered  through  rates  may 
fluctuate.

Capital expenditures for environmental improvements at regulated facilities 
were approximately:

• 

• 

• 

$50 million in 2018;

$61 million in 2017; and,

$93 million in 2016.

See Item 7 — Capital Requirements for further discussion.

Preparation  of  the  consolidated  financial  statements  and  disclosures  in 
compliance  with  GAAP  requires  the  application  of  accounting  rules  and 
guidance, as well as the use of estimates. Application of these policies involves 
judgments  regarding  future  events,  including  the  likelihood  of  success  of 
particular projects, legal and regulatory challenges and anticipated recovery 
of costs. These judgments could materially impact the consolidated financial 
statements and disclosures, based on varying assumptions. In addition, the 
financial and operating environment also may have a significant effect on the 
operation of the business and results reported. 

Accounting policies and estimates that are most significant to Xcel Energy’s 
results  of  operations,  financial  condition  or  cash  flows,  and  require 
management’s most difficult, subjective or complex judgments are outlined 
below. Each of these has a higher likelihood of resulting in materially different 
reported amounts under different conditions or using different assumptions. 
Each critical accounting policy has been reviewed and discussed with the 
Audit Committee of Xcel Energy Inc.’s Board of Directors on a quarterly basis.

Regulatory Accounting

Xcel Energy Inc. is subject to the accounting for Regulated Operations, which 
provides that rate-regulated entities report assets and liabilities consistent 
with the recovery of those incurred costs in rates, if it is probable that such 
rates will be charged and collected. Xcel Energy’s rates are derived through 
the ratemaking process, which results in the recording of regulatory assets 
and liabilities based on the probability of future cash flows. Regulatory assets 
generally  represent  incurred  or  accrued  costs  that  have  been  deferred 
because future recovery from customers is probable. Regulatory liabilities 
generally represent amounts that are expected to be refunded to customers 
in future rates or amounts collected in current rates for future costs. In other 
businesses or industries, regulatory assets and regulatory liabilities would 
generally be charged to net income or other comprehensive income.

Each  reporting  period  Xcel  Energy  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.  Decisions  made  by 
regulatory agencies can directly impact the amount and timing of cost recovery 
as well as the rate of return on invested capital, and may materially impact 
Xcel Energy’s results of operations, financial condition or cash flows.

As of Dec. 31, 2018 and 2017, Xcel Energy has recorded regulatory assets 
of $3.8 billion and $3.4 billion, respectively, and regulatory liabilities of $5.6 
billion and $5.3 billion, respectively. Each subsidiary is subject to regulation 
that varies from jurisdiction to jurisdiction. If future recovery of costs in any 
such  jurisdiction  is  no  longer  probable,  Xcel  Energy  would  be  required  to 
charge these assets to current net income or other comprehensive income. 
In assessing the probability of recovery of recognized regulatory assets, Xcel 
Energy noted no current or anticipated proposals or changes in the regulatory 
environment that it expects will materially impact the probability of recovery 
of the assets. 

See Note 4 to the consolidated financial statements for further information.

Income Tax Accruals

Judgment, uncertainty and estimates are a significant aspect of the income 
tax accrual process that accounts for the effects of current and deferred income 
taxes.  Uncertainty  associated  with  the  application  of  tax  statutes  and 
regulations and outcomes of tax audits and appeals require that judgment 
and estimates be made in the accrual process and in the calculation of the 
ETR.

Changes in tax laws and rates may affect recorded deferred tax assets and 
liabilities  and  our  future  ETR.  ETR  calculations  are  revised  every  quarter 
based on best available year-end tax assumptions, adjusted in the following 
year after returns are filed. The tax accrual estimates being trued-up to the 
actual  amounts  claimed  on  the  tax  returns  and  further  adjusted  after 
examinations by taxing authorities, as needed.

In accordance with the interim period reporting guidance, income tax expense 
for the first three quarters in a year is based on the forecasted annual ETR. 
The  forecasted  ETR  reflects  a  number  of  estimates  including  forecasted 
annual income, permanent tax adjustments and tax credits.

Valuation allowances are applied to deferred tax assets if it is more likely than 
not  that  at  least  a  portion  may  not  be  realized  based  on  an  evaluation  of 
expected future taxable income. Accounting for income taxes also requires 
that only tax benefits that meet the more likely than not recognition threshold 
can  be  recognized  or  continue  to  be  recognized.  We  may  adjust  our 
unrecognized tax benefits and interest accruals as disputes with the IRS and 
state tax authorities are resolved, and as new developments occur. These 
adjustments may increase or decrease earnings. 

See Note 7 to the consolidated financial statements for further information.

Employee Benefits

Xcel Energy sponsors several noncontributory, defined benefit pension plans 
and other postretirement benefit plans that cover almost all employees and 
certain retirees. Projected benefit costs are based on historical information 
and actuarial calculations that include a number of key assumptions (e.g., 
annual  return  level  on  pension  and  postretirement  health  care  investment 
assets, discount rates, mortality rates and health care cost trend rates). In 
addition, the pension cost calculation uses an asset-smoothing methodology 
to  reduce  the  volatility  of  investment  performance  over  time.  Pension 
assumptions are continually reviewed by Xcel Energy.. 

At Dec. 31, 2018, Xcel Energy set the rate of return on assets used to measure 
pension costs at 6.87%, which is consistent with the rate set at Dec. 31, 2017. 
The rate of return used to measure postretirement health care costs is 5.30% 
at Dec. 31, 2018, which represents a 50 basis point decrease from Dec. 31, 
2017. Xcel Energy’s pension investment strategy is based on plan-specific 
investments that seek to minimize investment and interest rate risk as a plan’s 
funded  status  increases  over  time.  This  strategy  results  in  a  greater 
percentage of interest rate sensitive securities being allocated to plans having 
relatively  higher  funded  status  ratios  and  a  greater  percentage  of  growth 
assets being allocated to plans having relatively lower funded status ratios.

Xcel Energy set the discount rates used to value the pension obligations at 
4.31% and postretirement health care obligations at 4.32% at Dec. 31, 2018. 
This represents a 68 basis point and 70 basis point increase, respectively, 
from Dec. 31, 2017. Xcel Energy uses a bond matching study as its primary 
basis  for  determining  the  discount  rate  used  to  value  pension  and 
postretirement health care obligations. The bond matching study utilizes a 
portfolio of high grade (Aa or higher) bonds that matches the expected cash 
flows of Xcel Energy’s benefit plans in amount and duration. 

The effective yield on this cash flow matched bond portfolio determines the 
discount rate for the individual plans. The bond matching study is validated 
for reasonableness against the Merrill Lynch Corporate 15+ Bond Index. In 
addition, Xcel Energy reviews general actuarial survey data to assess the 
reasonableness of the discount rate selected.

If Xcel Energy were to use alternative assumptions at Dec. 31, 2018, a 1% 
change would result in the following impact on 2018 pension costs:

These costs include the effects of regulation.

Mortality rates are developed from actual and projected plan experience for 
pension plan and postretirement benefits. Xcel Energy’s actuary conducts an 
experience study periodically as part of the process to determine an estimate 
of mortality. Xcel Energy considers standard mortality tables, improvement 
factors and the plans actual experience when selecting a best estimate.

As of Dec. 31, 2018 the initial medical trend cost claim assumptions for Pre-65 
was 6.5% and Post-65 was 5.3%. The ultimate trend assumption remained 
at 4.5% for both Pre-65 and Post-65 claims costs. The period from initial trend 
rate until the ultimate rate is reached is four years. Xcel Energy bases its 
medical trend assumption on the long-term cost inflation expected in the health 
care market, considering the levels projected and recommended by industry 
experts, as well as recent actual medical cost experienced by Xcel Energy’s 
retiree medical plan.

A  1%  change  in  the  assumed  health  care  cost  trend  rate  would  have  the 
following effects on Xcel Energy:

Funding requirements in 2019 are expected to remain consistent with 2018, 
continue at that level in 2020 and begin to decline in the following years. While 
investment returns were below the assumed levels in 2016 and exceeded 
assumed levels in 2017, investment returns were below the assumed levels 
in 2018.

The  pension  cost  calculation  uses  a  market-related  valuation  of  pension 
assets. Xcel Energy uses a calculated value method to determine the market-
related value of the plan assets. The market-related value is determined by 
adjusting the fair market value of assets at the beginning of the year to reflect 
the investment gains and losses (the difference between the actual investment 
return and the expected investment return on the market-related value) during 
each of the previous five years at the rate of 20% per year. As differences 
between actual and expected investment returns are incorporated into the 
market-related  value,  amounts  are  recognized  in  pension  cost  over  the 
expected  average  remaining  years  of  service  for  active  employees 
(approximately 13 years in 2018).

Xcel  Energy  currently  projects  the  pension  costs  recognized  for  financial 
reporting purposes will be $114 million in 2019 and $107 million in 2020, while 
the actual pension costs were $140 million in 2018 and $139 million in 2017. 
The expected decrease in 2019 and future year costs is primarily due the 
settlement charge experienced in 2018 and reductions in loss amortizations.

Pension funding contributions across all four of Xcel Energy’s pension plans, 
both voluntary and required, for 2016 - 2019:

• 

• 

• 

• 

$150 million in January 2019;

$150 million in 2018;

$162 million in 2017; and,

$125 million in 2016

Future amounts may change based on actual market performance, changes 
in interest rates and any changes in governmental regulations. Therefore, 
additional contributions could be required in the future. 

Xcel Energy contributed $11 million, $20 million and $18 million during 2018, 
2017 and 2016, respectively, to the postretirement health care plans. Xcel 
Energy expects to contribute approximately $11 million during 2019.

Regulatory Commissions in Colorado, Texas, New Mexico and FERC 
jurisdictions allow the recovery of other postretirement benefit costs only 
to the extent that recognized expense is matched by cash contributions 
to an irrevocable trust.  Xcel Energy has consistently funded at a level 
to allow full recovery of costs in these jurisdictions.

PSCo and SPS recognize pension expense in all regulatory jurisdictions 
based on expense consistent with accounting guidance. The Texas and 
Colorado  electric  retail  jurisdictions  and  the  Colorado  gas  retail 
jurisdiction,  each  record  the  difference  between  annual  recognized 
pension expense and the annual amount of pension expense approved 
in their last respective general rate case as a deferral to a regulatory 
asset.

In  2018,  PSCo  was  required  to  create  a  regulatory  liability  to  adjust 
postretirement health care costs to zero in order to match the amounts 
collected in rates in the Colorado Gas retail jurisdiction.

See Note 11 to the consolidated financial statements for further information.

Nuclear Decommissioning

Xcel Energy recognizes liabilities for the expected cost of retiring tangible 
long-lived  assets  for  which  a  legal  obligation  exists.  These  AROs  are 
recognized at fair value as incurred and are capitalized as part of the cost of 
the related long-lived assets. In the absence of quoted market prices, Xcel 
Energy estimates the fair value of its AROs using present value techniques, 
in which it makes assumptions including estimates of the amounts and timing 
of future cash flows associated with retirement activities, credit-adjusted risk 
free  rates  and  cost  escalation  rates.  When  Xcel  Energy  revises  any 
assumptions,  it  adjusts  the  carrying  amount  of  both  the ARO  liability  and  
related long-lived asset. ARO liabilities are accreted to reflect the passage of 
time using the interest method.

36

A  significant  portion  of  Xcel  Energy’s  AROs  relates 
future 
facilities.  The  nuclear 
decommissioning  of  NSP-Minnesota’s  nuclear 
decommissioning obligation is funded by the external decommissioning trust 
fund. Difference between regulatory funding (including depreciation expense 
less returns from the external trust fund) and expense recognized is deferred 
as a regulatory asset. The amounts recorded for AROs related to future nuclear 
decommissioning were $1.968 billion in 2018 and $1.874 billion in 2017. 

the 

to 

NSP-Minnesota obtains periodic independent cost studies in order to estimate 
the cost and timing of planned nuclear decommissioning activities. Estimates 
of future cash flows are highly uncertain and may vary significantly from actual 
results. NSP-Minnesota is required to file a nuclear decommissioning filing 
every three years. The filing covers all expenses for the decommissioning of 
the  nuclear  plants,  including  decontamination  and  removal  of  radioactive 
material.

The most recent triennial filing was approved by the MPUC in January 2019 
and  resulted  in  no  change  to  the  accrual.  The  2020  accrual  will  be  set 
subsequent to a compliance filing that is expected to be submitted in July 
2019. 

The following assumptions have a significant effect on the estimated nuclear 
obligation:

Timing — Decommissioning cost estimates are impacted by each facility’s 
retirement date and timing of the actual decommissioning activities. Estimated 
retirement dates coincide with the expiration of each unit’s operating license 
with the NRC (i.e., 2030 for Monticello and 2033 and 2034 for PI’s Unit 1 and 
2, respectively). The estimated timing of the decommissioning activities is 
based  upon  the  DECON  method,  which  assumes  prompt  removal  and 
dismantlement. The use of the DECON method is required by the MPUC.  
Decommissioning activities are expected to begin at the end of the license 
date and be completed for both facilities by 2091.

Technology  and  Regulation  —  There  is  limited  experience  with  actual 
decommissioning  of  large  nuclear  facilities.  Changes  in  technology, 
experience and regulations could cause cost estimates to change significantly. 

Escalation Rates — Escalation rates represent projected cost increases due 
to general inflation and increases in the cost of decommissioning activities. 
NSP-Minnesota used an escalation rate of 3.4% in calculating the ARO for 
nuclear  decommissioning  of  its  nuclear  facilities,  based  on  the  weighted 
averages of labor and non-labor escalation factors calculated by Goldman 
Sachs Asset Management.

Discount Rates — Changes in timing or estimated cash flows that result in 
upward  revisions  to  the ARO  are  calculated  using  the  then-current  credit-
adjusted risk-free interest rate. The credit-adjusted risk-free rate in effect when 
the change occurs is used to discount the revised estimate of the incremental 
expected  cash  flows  of  the  retirement  activity.  If  the  change  in  timing  or 
estimated expected cash flows results in a downward revision of the ARO, 
the undiscounted revised estimate of expected cash flows is discounted using 
the credit-adjusted risk-free rate in effect at the date of initial measurement 
and  recognition  of 
from 
approximately 4% to 7% have been used to calculate the net present value 
of the expected future cash flows over time.

the  original  ARO.  Discount  rates  ranging 

Significant uncertainties exist in estimating future costs including the method 
to  be  utilized,  ultimate  costs  to  decommission  and  planned  method  of 
disposing  spent  fuel.  If  different  cost  estimates,  life  assumptions  or  cost 
escalation rates were utilized, the AROs could change materially. However, 
changes in estimates have minimal impact on results of operations as NSP-
Minnesota expects to continue to recover all costs in future rates.

Xcel  Energy  continually  makes  judgments  and  estimates  related  to  these 
critical accounting policy areas, based on an evaluation of the assumptions 
and uncertainties for each area. The information and assumptions of these 
judgments and estimates will be affected by events beyond the control of Xcel 
Energy,  or  otherwise  change  over  time.  This  may  require  adjustments  to 
recorded results to better reflect updated information that becomes available. 
The accompanying financial statements reflect management’s best estimates 
and judgments of the impact of these factors as of Dec. 31, 2018.

See Note 12 to the consolidated financial statements for further information.

Derivatives, Risk Management and Market Risk

Xcel Energy Inc. and its subsidiaries are exposed to a variety of market risks 
in the normal course of business. Market risk is the potential loss that may 
occur as a result of adverse changes in the market or fair value of a particular 
instrument  or  commodity. All  financial  and  commodity-related  instruments, 
including derivatives, are subject to market risk. 

See Note 10 to the consolidated financial statements for further information.

Xcel Energy is exposed to the impact of adverse changes in price for energy 
and  energy-related  products,  which  is  partially  mitigated  by  the  use  of 
commodity  derivatives.  In  addition  to  ongoing  monitoring  and  maintaining 
credit  policies  intended  to  minimize  overall  credit  risk,  management  takes 
steps to mitigate changes in credit and concentration risks associated with its 
derivatives and other contracts, including parental guarantees and requests 
of collateral. While Xcel Energy expects that the counterparties will perform 
under  the  contracts  underlying  its  derivatives,  the  contracts  expose  Xcel 
Energy to certain credit and non-performance risk.

Distress in the financial markets may impact counterparty risk, the fair value 
of the securities in the nuclear decommissioning fund and pension fund and 
Xcel Energy’s ability to earn a return on short-term investments. 

Commodity Price Risk — Xcel Energy Inc.’s utility subsidiaries are exposed 
to commodity price risk in their electric and natural gas operations. Commodity 
price risk is managed by entering into long- and short-term physical purchase 
and sales contracts for electric capacity, energy and energy-related products 
and fuels used in generation and distribution activities. Commodity price risk 
is  also  managed  through  the  use  of  financial  derivative  instruments.  Xcel 
Energy’s risk management policy allows it to manage commodity price risk 
within each rate-regulated operation per commission approved hedge plans.

Wholesale  and  Commodity  Trading  Risk  —  Xcel  Energy  Inc.’s  utility 
subsidiaries  conduct  various  wholesale  and  commodity  trading  activities, 
including the purchase and sale of electric capacity, energy, energy-related 
instruments and natural gas-related instruments, including derivatives. Xcel 
Energy’s  risk  management  policy  allows  management  to  conduct  these 
activities within guidelines and limitations as approved by its risk management 
committee.

At Dec. 31, 2018, a 10% increase in market prices for commodity trading 
contracts  would  increase  pretax  income  by  approximately  $16  million, 
whereas a 10% decrease would decrease pretax income by approximately 
$16 million. At Dec. 31, 2017, a 10% increase or decrease in market prices 
for commodity trading contracts would have an immaterial impact.

Xcel  Energy  Inc.’s  utility  subsidiaries’  wholesale  and  commodity  trading 
operations  measure  the  outstanding  risk  exposure  to  price  changes  on 
transactions,  contracts  and  obligations  using  VaR.  VaR  expresses  the 
potential change in fair value on the outstanding transactions, contracts and 
obligations over a particular period of time under normal market conditions.

VaRs  for  the  NSP-Minnesota  and  PSCo  commodity  trading  operations, 
calculated on a consolidated basis using a Monte Carlo simulation with a 95% 
confidence level and a one-day holding period:

In  November  2018,  management  temporarily  increased  the  VaR  limit  to 
accommodate a 10-year transaction. NSP-Minnesota has been systematically 
hedging the transaction and the consolidated VaR returned below $3 million 
in January 2019.

Nuclear  Fuel  Supply  —  NSP-Minnesota  is  scheduled  to  take  delivery  of 
approximately 24% of its 2019 and approximately 54% of its 2020 enriched 
nuclear material requirements from sources that could be impacted by events 
in Ukraine and extended sanctions against Russia. Long-term, through 2024, 
NSP-Minnesota  is  scheduled  to  take  delivery  of  approximately  32%  of  its 
average enriched nuclear material requirements from these sources. Alternate 
potential sources provide the flexibility to manage NSP-Minnesota’s nuclear 
fuel  supply.  NSP-Minnesota  periodically  assesses  if  further  actions  are 
required to assure a secure supply of enriched nuclear material.

Disruptions in third party nuclear fuel supply contracts due to bankruptcies or 
change  of  contract  assignments  have  not  materially  impacted  NSP-
Minnesota’s operational or financial performance. 

Interest Rate Risk — Xcel Energy is subject to interest rate risk. Xcel Energy’s 
risk management policy allows interest rate risk to be managed through the 
use of fixed rate debt, floating rate debt and interest rate derivatives such as 
swaps, caps, collars and put or call options.

37

A 100 basis point change in the benchmark rate on Xcel Energy’s variable 
rate debt would impact annual pretax interest expense by approximately $10 
million in 2018 and $9 million in 2017. 

NSP-Minnesota maintains a nuclear decommissioning fund, as required by 
the NRC. The nuclear decommissioning fund is subject to interest rate risk 
and equity price risk. The fund is invested in a diversified portfolio of cash 
equivalents, debt securities, equity securities and other investments. These 
investments  may  be  used  only  for  the  purpose  of  decommissioning  NSP-
Minnesota’s nuclear generating plants. 

Realized and unrealized gains on the decommissioning fund investments are 
deferred  as  an  offset  of  NSP-Minnesota’s  regulatory  asset  for  nuclear 
decommissioning costs. Fluctuations in equity prices or interest rates affecting 
the nuclear decommissioning fund do not have a direct impact on earnings 
due  to  the  application  of  regulatory  accounting.  See  Note  10  to  the 
consolidated financial statements for further information.

Changes in discount rates and expected return on plan assets impact the 
value of pension and postretirement plan assets as well as benefit costs. 

See Note 11 to the consolidated financial statements for further information.

Credit Risk — Xcel Energy Inc. and its subsidiaries are also exposed to credit 
risk.  Credit  risk  relates  to  the  risk  of  loss  resulting  from  counterparties’ 
nonperformance  on  their  contractual  obligations.  Xcel  Energy  Inc.  and  its 
subsidiaries maintain credit policies intended to minimize overall credit risk 
and actively monitor these policies to reflect changes and scope of operations.

At Dec. 31, 2018, a 10% increase in commodity prices would have resulted 
in an increase in credit exposure of $14 million, while a decrease in prices of 
10% would have resulted in an increase in credit exposure of $3 million. At 
Dec. 31, 2017, a 10% increase in commodity prices would have resulted in 
an increase in credit exposure of $26 million, while a decrease in prices of 
10% would have resulted in an increase in credit exposure of $7 million.

Xcel  Energy  Inc.  and  its  subsidiaries  conduct  credit  reviews  for  all 
counterparties  and  employ  credit  risk  controls,  such  as  letters  of  credit, 
parental guarantees, master netting agreements and termination provisions. 
Credit exposure is monitored, and when necessary, the activity with a specific 
counterparty is limited until credit enhancement is provided. Distress in the 
financial markets could increase Xcel Energy’s credit risk.

Fair Value Measurements

Xcel Energy uses derivative contracts such as futures, forwards, interest rate 
swaps, options and FTRs to manage commodity price and interest rate risk. 
Derivative  contracts,  with  the  exception  of  those  designated  as  normal 
purchase-normal  sale  contracts,  are  reported  at  fair  value.  Xcel  Energy’s 
investments held in the nuclear decommissioning fund, rabbi trusts, pension 
and other postretirement funds are also subject to fair value accounting. 

See  Notes  10  and  11  to  the  consolidated  financial  statements  for  further 
information.

Commodity Derivatives — Xcel Energy monitors the creditworthiness of the 
counterparties  to  its  commodity  derivative  contracts  and  assesses  each 
counterparty’s ability to perform on the transactions. Given the typically short 
duration of these contracts, the impact of discounting commodity derivative 
assets  for  counterparty  credit  risk  was  not  material  to  the  fair  value  of 
commodity derivative assets at Dec. 31, 2018. 

Adjustments to fair value for credit risk of commodity trading instruments are 
recorded in electric revenues. Credit risk adjustments for other commodity 
derivative  instruments  are  recorded  as  other  comprehensive  income  or 
deferred  as  regulatory  assets  and  liabilities.  Classification  as  a  regulatory 
asset  or  liability  is  based  on  commission  approved  regulatory  recovery 
mechanisms. The impact of discounting commodity derivative liabilities for 
credit risk was immaterial at Dec. 31, 2018.

Net cash provided by operating activities decreased by $4 million for 2018 as 
compared to 2017. Change was primarily due to refunds associated with the 
TCJA and timing of certain electric and natural gas recovery mechanisms, 
partially offset by the change in net income (excluding amounts related to non-
cash operating activities (e.g., depreciation and deferred tax expenses)).

Net cash provided by operating activities increased by $74 million for 2017
as  compared  to  2016.  Increase  was  primarily  due  to  higher  net  income, 
excluding amounts related to non-cash operating activities (e.g., depreciation 
and deferred tax expenses) and timing of customer receipts, partially offset 
by  higher  interest  payments  and  pension  contributions,  refunds,  timing  of 
vendor payments and lower income tax refunds.

Net cash used in investing activities increased by $690 million for 2018 as

for the Rush Creek, Foxtail and Hale wind generation facilities.

Net cash used in investing activities increased by $35 million for 2017 as 
compared to 2016. Increase was mainly attributable to capital expenditures 
related to the Rush Creek wind generation facility, partially offset by amounts 
for the Courtenay wind farm and less rabbi trust investments.

Net cash provided by financing activities increased by $760 million for 2018
as compared to 2017. Increase was primarily due to lower repayments of long-
term debt, proceeds from the issuances of common stock and additional debt 
financings, partially offset by lower short-term debt proceeds as compared to 
2017.

Net cash provided by financing activities decreased by $41 million for 2017
as compared to 2016. Decrease was primarily due to lower proceeds from 
debt issuances and higher dividend payments, partially offset by higher short-
term debt proceeds and lower repurchases of common stock in 2017.

Capital Requirements
Xcel Energy expects to meet future financing requirements by periodically issuing short-term debt, long-term debt, common stock, hybrid and other securities 
to maintain desired capitalization ratios.
Contractual Obligations and Other Commitments — Xcel Energy has contractual obligations and other commitments that will need to be funded in the 
future. Contractual obligations and other commercial commitments as of Dec. 31, 2018 were as follows:

Common Stock Dividends — Future dividend levels will be dependent on 
Xcel  Energy’s  results  of  operations,  financial  condition,  cash  flows, 
reinvestment opportunities and other factors, and will be evaluated by the Xcel 
Energy Inc. Board of Directors. In February 2019, Xcel Energy announced a 
quarterly dividend of $0.405 per share, which represents an increase of 6.6%. 
Xcel Energy’s dividend policy balances the following:

Short-Term  Investments  —  Xcel  Energy  Inc.,  NSP-Minnesota,  NSP-
Wisconsin,  PSCo  and  SPS  maintain  cash  operating  and  short-term 
investment accounts. 

Short-Term  Debt  —  Xcel  Energy  Inc.,  NSP-Minnesota,  NSP-Wisconsin, 
PSCo and SPS each have individual commercial paper programs. Authorized 
levels for these commercial paper programs are:

•

• 

• 

$1 billion for Xcel Energy Inc.;

$700 million for PSCo;

$500 million for NSP-Minnesota;

$400 million for SPS; and,

$150 million for NSP-Wisconsin.

In addition, Xcel Energy Inc. has a 364-day term loan agreement to borrow 
up  to  $500  million. As  of  Dec.  31,  2018,  $250  million  of  borrowings  were 
outstanding with $250 million additional borrowing capacity. In February 2019, 
Xcel Energy borrowed the remaining $250 million. No additional borrowing

In addition, there are certain statutory limitations that could affect dividend 
levels. Federal law places limits on the ability of public utilities within a holding 
company system 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 Note 5 to the consolidated financial statements for further information.

Registration  Statements  —  Xcel  Energy  Inc.’s Articles  of  Incorporation 
authorize the issuance of one billion shares of $2.50 par value common stock. 
As of Dec. 31, 2018 and 2017, Xcel Energy Inc. had approximately 514 million 
shares and 508 million shares of common stock outstanding, respectively. 

Xcel Energy Inc. and its utility subsidiaries have registration statements on 
file with the SEC pursuant to which they may sell securities from time to time. 
These registration statements, which are uncapped, permit Xcel Energy Inc. 
and its utility subsidiaries to issue debt and other securities in the future at 
amounts, prices and with terms to be determined at the time of future offerings, 
and in the case of our utility subsidiaries, subject to commission approval.

Planned Financing Activity — Xcel Energy Inc. and its utility subsidiaries’ 
2019 financing plans reflect the following:

• 

• 

• 

Xcel Energy Inc. —  approximately $700 million of senior notes and 
approximately $75 to $80 million of equity through the DRIP and 
benefit programs;
NSP-Minnesota —  approximately $900 million of first mortgage 
bonds;
PSCo —  approximately $800 million of first mortgage bonds; and,

SPS — approximately $300 million of first mortgage bonds. 

• 
Forward Equity Agreements — In November 2018, Xcel Energy Inc. entered 
into forward sale agreements in connection with a completed $459 million 
public offering of 9.4 million shares of Xcel Energy common stock. The initial 
forward  agreement  was  for  8.1  million  shares  with  an  additional  forward 
agreement  of  1.2  million  shares  exercised  at  the  option  of  the  banking 
counterparty. At  Dec.  31,  2018,  the  forward  agreements  could  have  been 
settled with physical delivery of 9.4 million common shares to the banking 
counterparty in exchange for cash of $456 million. The forward instruments 
could also have been settled at Dec. 31, 2018 with delivery of approximately 
$24 million of cash or approximately 0.5 million shares of common stock to 
the banking counterparty, if Xcel Energy unilaterally elected net cash or net 
share settlement, respectively.

The forward price used to determine amounts due at settlement is calculated 
based on the November 2018 public offering price for Xcel Energy’s common 
stock of $49.00, increased for the overnight bank funding rate, less a spread 
of 0.75% and less expected dividends on Xcel Energy’s common stock during 
the period the instruments are outstanding.

Xcel Energy may settle the forward agreements at any time up to the maturity 
date of February 7, 2020. The cash proceeds, depending on the timing of 
settlement, are expected to be approximately $450 million to $460 million. 

Forward equity instruments were accounted for as stockholders’ equity and 
recorded at fair value at the execution of the forward agreements, and will not 
be subsequently adjusted for changes in fair value until settlement. 

ATM Equity Offering — In 2018, Xcel Energy issued 4.7 million shares of 
common stock with net proceeds of $224.7 million through the at the market 
program.  In  addition,  total  transaction  fees  of  $1.9  million  were  paid.  In 
November 2018, the ATM offering was closed. 

Other Equity — Xcel Energy also plans to issue approximately $75 to $80 
million of equity, each year, through the DRIP and benefit programs during 
the five-year forecast time period. 

Long-Term Borrowings and Other Financing Instruments — See Note 5 
to the consolidated financial statements for further information.

Off-Balance-Sheet Arrangements

Xcel Energy does not have any off-balance-sheet arrangements, other than 
those currently disclosed, that have or are reasonably likely to have a current 
or future effect on financial condition, changes in financial condition, revenues 
or expenses, results of operations, liquidity, capital expenditures or capital 
resources that is material to investors.

Earnings Guidance

2019 GAAP and ongoing earnings guidance is a range of $2.55 to $2.65 per 
share.(a) Key assumptions: 
• 

Constructive outcomes in all rate case and regulatory proceedings.

Normal weather patterns for the year.

• 
•  Weather-normalized retail electric sales are projected to be relatively 

consistent with 2018 levels.

•  Weather-normalized retail natural gas sales are projected to be within a 

• 

• 

• 

• 

• 

• 

• 

• 

• 

range of 0.0% to 1.0% over 2018 levels.
Capital rider revenue is projected to increase $115 million to $125 million 
(net of PTCs) over 2018 levels. PTCs are flowed back to customers, 
primarily through capital riders as reductions to electric margin.
Purchase capacity costs are expected to decline $25 million to $30 million 
compared with 2018 levels.

O&M expenses are projected to be consistent with 2017 levels.

Depreciation expense is projected to increase approximately $120 million 
to  $130  million  over  2018  levels.  Depreciation  expense  includes  $34 
million for the amortization of a prepaid pension asset at PSCo, which is 
TCJA related and will not impact earnings.

Property taxes are projected to increase approximately $15 million to 
$25 million over 2018 levels.

Interest expense (net of AFUDC — debt) is projected to increase $90 
million to $100 million over 2018 levels.

AFUDC — equity is projected to decrease approximately $20 million to 
$30 million from 2018 levels.

The ETR is projected to be approximately 6% to 8%. The ETR reflects 
benefits of PTCs which are flowed back to customers through electric 
margin.

Assumptions do not include the impact for the upcoming adoption of the 
new lease accounting standard, effective 2019.  Xcel Energy does not 
expect changes in the accounting for leases to impact earnings, but it 
may  result  in  variations  in  certain  line  items  within  the  statement  of  
income.

(a)   Ongoing earnings is calculated using net income and adjusting for certain nonrecurring or 
infrequent  items  that  are,  in  management’s  view,  not  reflective  of  ongoing  operations. 
Ongoing earnings could differ from those prepared in accordance with GAAP for unplanned 
and/or unknown adjustments. Xcel Energy is unable to forecast if any of these items will 
occur  or  provide  a  quantitative  reconciliation  of  the  guidance  for  ongoing  EPS  to 
corresponding GAAP EPS.

Management Report on Internal Controls Over Financial Reporting

The management of Xcel Energy Inc. is responsible for establishing and maintaining adequate internal control over financial reporting.  Xcel Energy Inc.’s 
internal control system was designed to provide reasonable assurance to Xcel Energy Inc.’s management and board of directors regarding the preparation 
and fair presentation of published financial statements.

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.

Xcel Energy Inc. management assessed the effectiveness of Xcel Energy Inc.’s internal control over financial reporting as of Dec. 31, 2018.  In making this 
assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated 
Framework (2013).  Based on our assessment, we believe that, as of Dec. 31, 2018, Xcel Energy Inc.’s internal control over financial reporting is effective at 
the reasonable assurance level based on those criteria.

Xcel Energy Inc.’s independent registered public accounting firm has issued an audit report on the Xcel Energy Inc.’s internal control over financial reporting.  
Its report appears herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of Xcel Energy Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Xcel Energy Inc. and subsidiaries (the "Company") as of December 31, 2018 and 2017, 
the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended 
December 31, 2018, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the "financial statements"). We also have 
audited the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 
and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with accounting 
principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control 
over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, 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 Report on Internal Controls over Financial Reporting. 
Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on 
our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over 
financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to 
error or fraud, and performing procedures to 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. Our audit of internal control over financial reporting included obtaining an understanding 
of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness 
of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. 
We believe that our audits provide a reasonable basis for our opinions.

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.

XCEL ENERGY INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements

1.  Summary of Significant Accounting Policies

General — Xcel Energy Inc.’s utility subsidiaries are engaged in the regulated 
generation, purchase, transmission, distribution and sale of electricity and in 
the regulated purchase, transportation, distribution and sale of natural gas.

Xcel Energy’s regulated operations include the activities of NSP-Minnesota, 
NSP-Wisconsin, PSCo and SPS. These utility subsidiaries serve electric and 
natural gas customers in portions of Colorado, Michigan, Minnesota, New 
Mexico, North Dakota, South Dakota, Texas and Wisconsin. Also included in 
regulated operations are WGI, an interstate natural gas pipeline company, 
and WYCO, a joint venture with CIG to develop and lease natural gas pipeline, 
storage and compression facilities.

Xcel  Energy  Inc.’s  nonregulated  subsidiaries  include  Eloigne  and  Capital 
Services. Eloigne invests in rental housing projects that qualify for low-income 
housing tax credits. Capital Services procures equipment for construction of 
renewable generation facilities at other subsidiaries. Xcel Energy Inc. owns 
the following additional direct subsidiaries, some of which are intermediate 
holding companies with additional subsidiaries: Xcel Energy Wholesale Group 
Inc.,  Xcel  Energy  Markets  Holdings  Inc.,  Xcel  Energy  Ventures  Inc.,  Xcel 
Energy Retail Holdings Inc., Xcel Energy Communications Group, Inc., Xcel 
Energy International Inc., Xcel Energy Transmission Holding Company, LLC, 
Nicollet  Holdings  Company,  LLC,  Nicollet  Project  Holdings  LLC  and  Xcel 
Energy Services Inc. Xcel Energy Inc. and its subsidiaries collectively are 
referred to as Xcel Energy.

Xcel  Energy’s  consolidated  financial  statements  include  its  wholly-owned 
subsidiaries and VIEs for which it is the primary beneficiary. All intercompany 
transactions  and  balances  are  eliminated,  unless  a  different  treatment  is 
appropriate for rate regulated transactions. 

Xcel Energy uses the equity method of accounting for its investment in WYCO. 
Xcel Energy’s equity earnings in WYCO are included on the consolidated 
statements of income as equity earnings of unconsolidated subsidiaries. 

Xcel Energy has investments in certain plants and transmission facilities jointly 
owned with nonaffiliated utilities. Xcel Energy’s proportionate share of jointly 
owned  facilities  is  recorded  as  property,  plant  and  equipment  on  the 
consolidated balance sheets, and Xcel Energy’s proportionate share of the 
operating costs associated with these facilities is included in its consolidated 
statements of income. See Note 3 for further information.

Xcel Energy’s consolidated financial statements are presented in accordance 
with GAAP. All of the utility subsidiaries’ underlying accounting records also 
conform to the FERC uniform system of accounts.

Xcel Energy has evaluated events occurring after Dec. 31, 2018 up to the 
date  of  issuance  of  these  consolidated  financial  statements.  Statements 
contain  all  necessary  adjustments  and  disclosures  resulting  from  that 
evaluation.

Use  of  Estimates  —  Xcel  Energy  uses  estimates  based  on  the  best 
information available in recording transactions and balances resulting from 
business operations. Estimates are used on items such as plant depreciable 
lives or potential disallowances, AROs, certain regulatory assets and liabilities, 
tax provisions, uncollectible amounts, environmental costs, unbilled revenues, 
jurisdictional  fuel  and  energy  cost  allocations  and  actuarially  determined 
benefit  costs.  Recorded  estimates  are  revised  when  better  information 
becomes available or actual amounts can be determined. Revisions can affect 
operating results.

Regulatory Accounting — Xcel Energy Inc.’s regulated utility subsidiaries 
account  for  income  and  expense  items  in  accordance  with  accounting 
guidance for regulated operations. Under this guidance:

• 

• 

Certain costs, which would otherwise be charged to expense or other 
comprehensive income, 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 other 
comprehensive income, 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.

Estimates  of  recovering  deferred  costs  and  returning  deferred  credits  are 
based on specific ratemaking decisions or precedent for each item. Regulatory 
assets and liabilities are amortized consistent with the treatment in the rate 
setting process.

If changes in the regulatory environment occur, the utility subsidiaries may no 
longer be eligible to apply this accounting treatment, and may be required to 
eliminate  regulatory  assets  and  liabilities  from  their  balance  sheets.  Such 
changes could have a material effect on Xcel Energy’s results of operations, 
financial condition or cash flows. 

See Note 4 for further information.

Income Taxes — Xcel Energy accounts for income taxes using the asset and 
liability  method,  which  requires  deferred  tax  assets  and  liabilities  for  the 
expected future tax consequences of events that have been included in the 
financial  statements.  Xcel  Energy  defers  income  taxes  for  all  temporary 
differences between pretax financial and taxable income, and between the 
book and tax bases of assets and liabilities. Xcel Energy uses the tax rates 
that are scheduled to be in effect when the temporary differences are expected 
to reverse. The effect of a change in tax rates on deferred tax assets and 
liabilities is recognized in the period that includes the enactment date.

The effects of tax rate changes that are attributable to the utility subsidiaries 
are generally subject to a normalization method of accounting. Therefore, the 
revaluation of most of the utility subsidiaries’ net deferred taxes upon a tax 
rate reduction results in the establishment of a net regulatory liability which 
will be refundable to utility customers over the remaining life of the related 
assets. A  tax  rate  increase  would  result  in  the  establishment  of  a  similar 
regulatory asset.  

Reversal of certain temporary differences are accounted for as current income 
tax expense due to the effects of past regulatory practices when deferred 
taxes  were  not  required  to  be  recorded  due  to  the  use  of  flow  through 
accounting for ratemaking purposes. Tax credits are recorded when earned 
unless there is a requirement to defer the benefit and amortize it over the book 
depreciable  lives  of  the  related  property.  The  requirement  to  defer  and 
amortize tax credits only applies to federal ITCs related to public utility property. 
Utility rate regulation also has resulted in the recognition of regulatory assets 
and liabilities related to income taxes.

Deferred tax assets are reduced by a valuation allowance if it is more likely 
than not that some portion or all of the deferred tax asset will not be realized.

Xcel  Energy  follows  the  applicable  accounting  guidance  to  measure  and 
disclose uncertain tax positions that it has taken or expects to take in its income 
tax returns. Xcel Energy recognizes a tax position in its consolidated financial 
statements when it is more likely than not that the position will be sustained 
upon examination based on the technical merits of the position. 

Recognition of changes in uncertain tax positions are reflected as a component 
of income tax.

49

Xcel Energy reports interest and penalties related to income taxes within the 
other income and interest charges in the consolidated statements of income.

Xcel  Energy  Inc.  and  its  subsidiaries  file  consolidated  federal  income  tax 
returns as well as consolidated or separate state income tax returns. Federal 
income taxes paid by Xcel Energy Inc. are allocated to its subsidiaries based 
on separate company computations. A similar allocation is made for state 
income taxes paid by Xcel Energy Inc. in connection with consolidated state 
filings. Xcel Energy Inc. also allocates its own income tax benefits to its direct 
subsidiaries.

See Note 7 for further information.

Property, Plant and Equipment and Depreciation — Property, plant and 
equipment is stated at original cost. The cost of plant includes direct labor and 
materials, contracted work, overhead costs and AFUDC. The cost of plant 
retired is charged to accumulated depreciation and amortization. Amounts 
recovered  in  rates  for  future  removal  costs  are  recorded  as  regulatory 
liabilities.  Significant  additions  or  improvements  extending  asset  lives  are 
capitalized, while repairs and maintenance costs are charged to expense as 
incurred. Maintenance and replacement of items determined to be less than 
a unit of property are charged to operating expenses as incurred. Planned 
maintenance  activities  are  charged  to  operating  expense  unless  the  cost 
represents the acquisition of an additional unit of property or the replacement 
of an existing unit of property.

Property, plant and equipment is tested for impairment when it is determined 
that  the  carrying  value  of  the  assets  may  not  be  recoverable. A  loss  is 
recognized in the current period if it becomes probable that part of a cost of 
a plant under construction or recently completed plant will be disallowed for 
recovery from customers and a reasonable estimate of the disallowance can 
be  made.  For  investments  in  property,  plant  and  equipment  that  are 
abandoned and not expected to go into service, incurred costs and related 
deferred tax amounts are compared to the discounted estimated future rate 
recovery, and a loss is recognized, if necessary.

Xcel Energy records depreciation expense using the straight-line method over 
the plant’s useful life. Actuarial life studies are performed and submitted to the 
state and federal commissions for review. Upon acceptance by the various 
commissions, the resulting lives and net salvage rates are used to calculate 
depreciation. Depreciation expense, expressed as a percentage of average 
depreciable property, was approximately 3.1% for 2018, 3.1% for 2017 and 
2.9% for 2016.

See Note 3 for further information.

AROs  — Xcel  Energy  Inc.’s  utility  subsidiaries  account  for  AROs  under 
accounting guidance that requires a liability for the fair value of an ARO to be 
recognized in the period in which it is incurred if it can be reasonably estimated, 
with the offsetting associated asset retirement costs capitalized as a long-
lived  asset.  The  liability  is  generally  increased  over  time  by  applying  the 
effective  interest  method  of  accretion,  and  the  capitalized  costs  are 
depreciated over the useful life of the long-lived asset. Changes resulting from 
revisions to the timing or amount of expected asset retirement cash flows are 
recognized as an increase or a decrease in the ARO. Xcel Energy Inc.’s utility 
subsidiaries also recover through rates certain future plant removal costs in 
addition to AROs. The accumulated removal costs for these obligations are 
reflected in the balance sheets as a regulatory liability. 

See Note 12 for further information.

Nuclear  Decommissioning  —  Nuclear  decommissioning  studies  that 
estimate  NSP-Minnesota’s  ultimate  costs  of  decommissioning  its  nuclear 
power plants are performed at least every three years and submitted to the 
state commissions for approval. 

For  ratemaking  purposes,  NSP-Minnesota  recovers  the  decommissioning 
costs of its nuclear power plants over each facility’s expected service life based 
on  the  triennial  decommissioning  studies. The  studies  consider  estimated 
future costs of decommissioning and the market value of investments in trust 
funds, and recommend annual funding amounts. Amounts collected in rates 
are  deposited  in  the  trust  funds.  For  financial  reporting  purposes,  NSP-
Minnesota accounts for nuclear decommissioning as an ARO.

Restricted funds for the payment of future decommissioning expenditures for 
NSP-Minnesota’s nuclear facilities are included in nuclear decommissioning 
fund and other assets on the consolidated balance sheets. 

See Note 10 for further information.

Benefit Plans and Other Postretirement Benefits — Xcel Energy maintains 
pension and postretirement benefit plans for eligible employees. Recognizing 
the cost of providing benefits and measuring the projected benefit obligation 
of  these  plans  requires  management  to  make  various  assumptions  and 
estimates.

Certain  unrecognized  actuarial  gains  and  losses  and  unrecognized  prior 
service costs or credits are deferred as regulatory assets and liabilities, rather 
than recorded as other comprehensive income, based on regulatory recovery 
mechanisms. 

See Note 11 for further information.

Environmental  Costs  —  Environmental  costs  are  recorded  when  it  is 
probable Xcel Energy is liable for remediation costs and the liability can be 
reasonably estimated. Costs are deferred as a regulatory asset if it is probable 
that the costs will be recovered from customers in future rates. Otherwise, the 
costs  are  expensed.  If  an  environmental  expense  is  related  to  facilities 
currently in use, such as emission-control equipment, the cost is capitalized 
and depreciated over the life of the plant.

Estimated remediation costs are regularly adjusted as estimates are revised 
and remediation proceeds. If other participating PRPs exist and acknowledge 
their potential involvement with a site, costs are estimated and recorded only 
for Xcel Energy’s expected share of the cost.  

Future  costs  of  restoring  sites  are  treated  as  a  capitalized  cost  of  plant 
retirement. The depreciation expense levels recoverable in rates include a 
provision for removal expenses. Removal costs recovered in rates before the 
related costs are incurred are classified as a regulatory liability.

See Note 12 for further information.

Revenue  From  Contracts  With  Customers  —  Performance  obligations 
related to the sale of energy are satisfied as energy is delivered to customers. 
Xcel Energy recognizes revenue that corresponds to the price of the energy 
delivered to the customer. The measurement of energy sales to customers is 
generally based on the reading of their meters, which occurs on a systematic 
basis throughout the month. At the end of each month, amounts of energy 
delivered to customers since the date of the last meter reading are estimated, 
and the corresponding unbilled revenue is recognized. 

Xcel  Energy  does  not  recognize  a  separate  financing  component  of  its 
collections from customers as contract terms are short-term in nature. Xcel 
Energy presents its revenues net of any excise or sales taxes or fees.

Xcel Energy’s utility subsidiaries recognize sales to customers on a gross 
basis in electric revenues and cost of sales. Revenues and charges for short 
term wholesale sales of excess energy transacted through RTOs are also 
recorded on a gross basis. Other RTO revenues and charges are recorded 
on a net basis in cost of sales.

See Note 6 for further information.

50

Cash  and  Cash  Equivalents  —  Xcel  Energy  considers  investments  in 
instruments with a remaining maturity of three months or less at the time of 
purchase, to be cash equivalents.

Commodity Trading Operations — All applicable gains and losses related 
to commodity trading activities are shown on a net basis in electric operating 
revenues in the consolidated statements of income.

Accounts Receivable and Allowance for Bad Debts — Accounts receivable 
are stated at the actual billed amount net of an allowance for bad debts. Xcel 
Energy  establishes  an  allowance  for  uncollectible  receivables  based  on  a 
policy that reflects its expected exposure to the credit risk of customers. As 
of Dec. 31, 2018 and 2017, the allowance for bad debts was $55 million and 
$52 million, respectively. 

Commodity trading activities are not associated with energy produced from 
Xcel Energy’s generation assets or energy and capacity purchased to serve 
native load. Commodity trading contracts are recorded at fair market value 
and  commodity  trading  results  include  the  impact  of  all  margin-sharing 
mechanisms. 

See Note 10 for further information.

Inventory  —  Inventory  is  recorded  at  average  cost  and  consisted  of  the 
following:

Fair Value Measurements — Xcel Energy presents cash equivalents, interest 
rate derivatives, commodity derivatives and nuclear decommissioning fund 
assets at estimated fair values in its consolidated financial statements. Cash 
equivalents are recorded at cost plus accrued interest; money market funds 
are measured using quoted NAVs. For interest rate derivatives, quoted prices 
based primarily on observable market interest rate curves are used to establish 
fair value. For commodity derivatives, the most observable inputs available 
are generally used to determine the fair value of each contract. In the absence 
of a quoted price, Xcel Energy may use quoted prices for similar contracts or 
internally prepared valuation models to determine fair value.

For the pension and postretirement plan assets and nuclear decommissioning 
fund, published trading data and pricing models, generally using the most 
observable inputs available, are utilized to estimate fair value for each security. 

See Notes 10 and 11 for further information.

Derivative  Instruments  —  Xcel  Energy  uses  derivative  instruments  in 
connection with its interest rate, utility commodity price, vehicle fuel price and 
commodity trading activities, including forward contracts, futures, swaps and 
options. Any derivative instruments not qualifying for the normal purchases 
and normal sales exception are recorded on the consolidated balance sheets 
at fair value as derivative instruments. Classification of changes in fair value 
for those derivative instruments is dependent on the designation of a qualifying 
hedging  relationship.  Changes  in  fair  value  of  derivative  instruments  not 
designated  in  a  qualifying  hedging  relationship  are  reflected  in  current 
earnings or as a regulatory asset or liability. Classification as a regulatory 
asset  or  liability  is  based  on  commission  approved  regulatory  recovery 
mechanisms.

Gains  or  losses  on  commodity  trading  transactions  are  recorded  as  a 
component of electric operating revenues; hedging transactions for vehicle 
fuel costs are recorded as a component of capital projects and O&M costs; 
and interest rate hedging transactions are recorded as a component of interest 
expense. 

Normal Purchases and Normal Sales — Xcel Energy enters into contracts for 
purchases and sales of commodities for use in its operations. At inception, 
contracts  are  evaluated  to  determine  whether  a  derivative  exists  and/or 
whether  an  instrument  may  be  exempted  from  derivative  accounting  if 
designated as a normal purchase or normal sale.

See Note 10 for further information.

51

AFUDC  — AFUDC  represents  the  cost  of  capital  used  to  finance  utility 
construction activity. AFUDC is computed by applying a composite financing 
rate  to  qualified  CWIP.  The  amount  of  AFUDC  capitalized  as  a  utility 
construction cost is credited to other nonoperating income (for equity capital) 
and  interest  charges  (for  debt  capital).  AFUDC  amounts  capitalized  are 
included in Xcel Energy’s rate base for establishing utility rates. 

Alternative Revenue — Certain rate rider mechanisms (including decoupling 
and  CIP/DSM  programs)  qualify  as  alternative  revenue  programs  under 
GAAP. These mechanisms arise from costs imposed upon the utility by action 
of a regulator or legislative body related to an environmental, public safety or 
other mandate. When certain criteria are met, such as collection within 24 
months, revenue is recognized equal to the revenue requirement, which may 
include incentives and return on rate base items. Billing amounts are revised 
periodically  for  differences  between  total  amount  collected  and  revenue 
earned, which may increase or decrease the level of revenue collected from 
customers. Alternative revenues arising from these programs are presented 
on a gross basis and disclosed separately from revenue from contracts with 
customers. 

See Note 6 for further information. 

Conservation Programs — Costs incurred for DSM and CIP programs are 
deferred  if  it  is  probable  future  revenue  will  recover  the  incurred  cost. 
Revenues recognized for incentive programs for the recovery of lost margins 
and/or conservation performance incentives are limited to amounts expected 
to be collected within 24 months from when they are earned. Regulatory assets 
are recognized to reflect the amount of costs or earned incentives that have 
not yet been collected from customers.

Emission Allowances  —  Emission  allowances  are  recorded  at  cost  plus 
broker commission fees. The inventory accounting model is utilized for all 
emission allowances and sales of these allowances are included in electric 
revenues.

Nuclear  Refueling  Outage  Costs  —  Xcel  Energy  uses  a  deferral  and 
amortization  method  for  nuclear  refueling  costs.  This  method  amortizes 
refueling outage costs over the period between refueling outages consistent 
with rate recovery.

RECs — Cost of RECs that are utilized for compliance is recorded as electric 
fuel  and  purchased  power  expense.  In  certain  jurisdictions,  Xcel  Energy 
reduces recoverable fuel costs for the cost of RECs and records that cost as 
a regulatory asset when the amount is recoverable in future rates.

Sales of RECs are recorded in electric revenues on a gross basis. The cost 
of  these  RECs  and  amounts  credited  to  customers  under  margin-sharing 
mechanisms are recorded in electric fuel and purchased power expense.

Recently Issued

3.  Property, Plant and Equipment

Major classes of property, plant and equipment:

Leases — In 2016, the FASB issued Leases, Topic 842 (ASU No. 2016-02), 
which  requires  balance  sheet  recognition  of  right-of-use  assets  and  lease 
liabilities for most leases. Adoption will occur on Jan. 1, 2019 utilizing the 
package  of  transition  practical  expedients  provided  by  the  new  standard, 
including carrying forward prior conclusions of whether agreements existing 
before  the  adoption  date  contain  leases,  and  whether  existing  leases  are 
operating  or  capital/finance  leases.  Xcel  Energy  expects  to  utilize  other 
expedients offered by the new standard and Leases, Topic 842 (ASU No. 
2018-11),  including  elections  to  not  recognize  short  term  leases  on  the 
consolidated balance sheet for certain classes of assets and to implement 
the standard on a prospective basis.  Xcel Energy’s implementation of the 
new  guidance  is  substantially  complete,  and  is  expected  to  result  in  the 
recognition  of  approximately  $2  billion  of  right-of-use  assets  and  lease 
liabilities in the first quarter of 2019 for operating leases for the use of real 
estate, equipment and certain natural gas generating facilities operated under 
PPAs. The implementation is not expected to have a significant impact on 
Xcel  Energy’s  consolidated  financial  statements,  other  than  first-time 
recognition of these operating leases on the consolidated balance sheet.

Joint Ownership of Generation, Transmission and Gas Facilities

The utility subsidiaries’ jointly owned assets as of Dec. 31, 2018:

Recently Adopted

Revenue Recognition — In 2014, the FASB issued Revenue from Contracts 
with  Customers,  Topic  606  (ASU  No.  2014-09),  which  provides  a  new 
framework  for  the  recognition  of  revenue.  Xcel  Energy  implemented  the 
guidance  on  a  modified  retrospective  basis  on  Jan.  1,  2018.  Results  for 
reporting periods beginning after Dec. 31, 2017 are presented in accordance 
with Topic 606, while prior period results have not been adjusted and continue 
to  be  reported  in  accordance  with  prior  accounting  guidance.  The 
implementation did not have a material impact on Xcel Energy’s consolidated 
financial statements, other than increased disclosures regarding revenues 
related to contracts with customers. 

Classification and Measurement of Financial Instruments — In 2016, the 
FASB issued Recognition and Measurement of Financial Assets and Financial 
Liabilities,  Subtopic  825-10  (ASU  No.  2016-01),  which  eliminated  the 
available-for-sale  classification  for  marketable  equity  securities  and  also 
replaced the cost method of accounting for non-marketable equity securities 
with a model for recognizing impairments and observable price changes. Xcel 
Energy implemented the guidance on Jan. 1, 2018 and the adoption impacts 
were not material. 

Presentation of Net Periodic Benefit Cost — In 2017, the FASB issued 
Improving the Presentation of Net Periodic Pension Cost and Net Periodic 
Postretirement Benefit Cost, Topic 715 (ASU No. 2017-07), which establishes 
that  only  the  service  cost  portion  of  pension  cost  may  be  presented  as  a 
component of operating income. In addition, only the service cost portion of 
pension cost is eligible for capitalization. As a result of regulatory accounting 
treatment,  a  similar  amount  of  pension  cost,  including  non-service 
components, will be recognized consistent with historical ratemaking and the 
impacts of adoption are limited to changes in classification of non-service 
costs in the consolidated statements of income. 

Xcel Energy implemented the new guidance on Jan. 1, 2018. As a result, $33 
million and $26 million of pension costs were retrospectively reclassified from 
operating  and  maintenance  expenses  to  other  expense,  net  on  the 
consolidated  statements  of  income  for  2017  and  2016,  respectively.  Xcel 
Energy used benefit cost amounts disclosed for prior periods as the basis for 
retrospective application.

4.   Regulatory Assets and Liabilities

Regulatory assets and liabilities are created for amounts that regulators may allow to be collected, or may require to be paid back to customers in future electric 
and natural gas rates. Xcel Energy would be required to recognize the write-off of regulatory assets and liabilities in net income or other comprehensive income 
if changes in the utility industry no longer allow for the application of regulatory accounting guidance under GAAP.

Term Loan Agreement — In December 2018, Xcel Energy Inc. renewed its $500 million 364-Day Term Loan Agreement with $250 million outstanding. In 
February 2019, Xcel Energy borrowed the remaining amount. No additional capacity remains as loans borrowed and repaid may not be redrawn. The loan is 
unsecured and matures Dec. 3, 2019. Xcel Energy has an option to request an extension through Dec. 2, 2020. Term loan includes one financial covenant, 
requiring Xcel Energy’s consolidated funded debt to total capitalization ratio to be less than or equal to 65 percent. Interest is at a rate equal to either (i) the 
Eurodollar rate, plus 50.0 basis points, or (ii) an alternate base rate. Xcel Energy is also required to pay a commitment fee equal to 10 basis points per annum 
on the unborrowed portion.

Letters of Credit — Xcel Energy Inc. and its subsidiaries use letters of credit, typically with terms of one year, to provide financial guarantees for certain 
operating obligations. As of Dec. 31, 2018 and 2017, there were $49 million and $30 million of letters of credit outstanding. Amounts approximate their fair 
value.

Credit Facilities — Xcel Energy Inc. and its utility subsidiaries must have revolving credit facilities in place at least equal to the amount of their commercial 
paper borrowing limits and cannot issue commercial paper exceeding available capacity under these credit facilities. The lines of credit provide short-term 
financing in the form of notes payable to banks, letters of credit and back-up support for commercial paper borrowings.

Each credit facility has a financial covenant requiring that the debt-to-total capitalization ratio be less than or equal to 65%. 

All extension requests are subject to majority bank group approval. 
The Xcel Energy Inc. credit facility has a cross-default provision that Xcel Energy Inc. will be in default on its borrowings under the facility if it or any of its subsidiaries (except NSP-Wisconsin 
as long as its total assets do not comprise more than 15% of Xcel Energy’s consolidated total assets) default on indebtedness in an aggregate principal amount exceeding $75 million.

If Xcel Energy Inc. or its utility subsidiaries do not comply with the covenant, an event of default may be declared, and if not remedied, any outstanding amounts 
due under the facility can be declared due by the lender. As of Dec. 31, 2018, Xcel Energy Inc. and its subsidiaries were in compliance with all financial covenants.

Forward Equity Agreements — In November 2018, Xcel Energy Inc. entered 
into forward sale agreements in connection with a completed $459 million 
public offering of 9.4 million shares of Xcel Energy common stock. The initial 
forward agreement was for 8.1 million shares with an additional agreement 
of 1.2 million shares exercised at the option of the banking counterparty. At 
Dec. 31, 2018, the forward agreements could have been settled with physical 
delivery of 9.4 million common shares to the banking counterparty in exchange 
for cash of $456 million. The forward instruments could also have been settled 
at  Dec.  31,  2018  with  delivery  of  approximately  $24  million  of  cash  or 
approximately 0.5 million shares of common stock to the counterparty, if Xcel 
Energy unilaterally elected net cash or net share settlement, respectively. The 
forward price used to determine amounts due at settlement is calculated based 
on the November 2018 public offering price for Xcel Energy’s common stock 
of $49.00, increased for the overnight bank funding rate, less a spread of 
0.75% and less expected dividends on Xcel Energy’s common stock during 
the period the instruments are outstanding. 

Xcel Energy may settle the agreements at any time up to the maturity date of 
February 7,  2020.  Depending  on  settlement  timing,  cash  proceeds  are 
expected to be approximately $450 million to $460 million. 

Forward equity instruments were recognized within stockholders’ equity at fair 
value at execution of the agreements, and will not be subsequently adjusted 
until settlement.   

ATM Equity Offering — Xcel Energy issued 4.7 million shares of common 
stock with net proceeds of $224.7 million through the at-the-market program. 
In addition, transaction fees of $1.9 million were paid. In November 2018, the 
ATM offering was closed. 

Other Equity — Xcel Energy  issued $38.5 million and $39.2 million of equity 
through the DRIP program during the years ended Dec. 31, 2018 and 2017 
respectively. Program allows stockholders to elect dividend reinvestment in 
Xcel Energy common stock through a non-cash transaction. See Note 8 for 
equity items related to share based compensation.

Income Taxes

Federal  Tax  Reform  —  In  2017,  the TCJA  was  signed  into  law. The  key 
provisions impacting Xcel Energy, generally beginning in 2018, include: 

• 

• 

• 

• 

• 

• 

• 

• 

Corporate federal tax rate reduction from 35% to 21%;

Normalization of resulting plant-related excess deferred taxes;

Elimination of the corporate alternative minimum tax;

Continued  interest  expense  deductibility  and  discontinued  bonus 
depreciation for regulated public utilities;

Limitations on certain executive compensation deductions;

Limitations on certain deductions for NOLs arising after Dec. 31, 2017 
(limited to 80% of taxable income); 

Repeal of the section 199 manufacturing deduction; and

Reduced deductions for meals and entertainment as well as state and 
local lobbying.

Xcel Energy estimated the effects of the TCJA, which have been reflected in 
the consolidated financial statements. 

Reductions in deferred tax assets and liabilities due to a decrease in corporate 
federal tax rates typically result in a net tax benefit. However, the impacts are 
primarily recognized as regulatory liabilities refundable to utility customers as 
a result of IRS requirements and past regulatory treatment.

Estimated impacts of the new tax law in December 2017 included:

• 

• 

• 

$2.7 billion ($3.8 billion grossed-up for tax) of reclassifications of plant-
related excess deferred taxes to regulatory liabilities upon valuation at 
the  new  21%  federal  rate. The  regulatory  liabilities  will  be  amortized 
consistent with IRS normalization requirements, resulting in customer 
refunds over an estimated weighted average period of approximately 30 
years;

$254 million and $174 million of reclassifications (grossed-up for tax) of 
excess  deferred  taxes  for  non-plant  related  deferred  tax  assets  and 
liabilities, respectively, to regulatory assets and liabilities; and, 

$23 million of total estimated income tax expense related to the tax rate 
change on certain non-plant deferred taxes and all other 2017 income 
statement impacts of the federal tax reform.

Xcel Energy accounted for the state tax impacts of federal tax reform based 
on enacted state tax laws. Any future state tax law changes related to the 
TCJA will be accounted for in the periods state laws are enacted.

Federal Tax Loss Carryback Claims — In 2012 - 2015, Xcel Energy identified 
certain expenses related to 2009, 2010, 2011, 2013, 2014 and 2015 that qualify 
for an extended carryback beyond the typical two-year carryback period. As 
a result of a higher tax rate in prior years, Xcel Energy recognized a tax benefit 
of approximately $5 million in 2015, $17 million in 2014, $12 million in 2013 
and $15 million in 2012.

consolidated federal income tax returns expire as follows:

In 2012, the IRS commenced an examination of tax years 2010 and 2011, 
including the 2009 carryback claim. In 2017, Xcel Energy and the Office of 
Appeals reached an agreement and the benefit related to the agreed upon 
portions was recognized. In the second quarter of 2018, the Joint Committee 
on Taxation completed its review and took no exception to the agreement. As 
a result, the remaining unrecognized tax benefit was released and recorded 
as a payable to the IRS.

In the third quarter of 2015, the IRS commenced an examination of tax years 
2012 and 2013. In the third quarter of 2017, the IRS concluded the audit of 
tax years 2012 and 2013 and proposed an adjustment that would impact Xcel 
Energy’s NOL and ETR. Xcel Energy filed a protest with the IRS. As of Dec. 
31, 2018, the case has been forwarded to the Office of Appeals and Xcel 
Energy has recognized its best estimate of income tax expense that will result 
from a final resolution of this issue; however, the outcome and timing of a 
resolution is unknown.

In the fourth quarter of 2018, the IRS began an audit of tax years 2014 - 2016, 
however no adjustments have been proposed.

State Audits — Xcel Energy files consolidated state tax returns based on 
income in its major operating jurisdictions and various other state income-
based tax returns.

As  of  Dec.  31,  2018,  Xcel  Energy’s  earliest  open  tax  years  (subject  to 
examination by state taxing authorities in its major operating jurisdictions) 
were as follows:

Payable for interest related to unrecognized tax benefits is partially offset by

Unrecognized Tax Benefits — Unrecognized tax benefit balance includes 
permanent tax positions, which if recognized would affect the annual ETR. In 
addition,  the  unrecognized  tax  benefit  balance  includes  temporary  tax 
positions for which the ultimate deductibility is highly certain, but for which 
there is uncertainty about the timing of such deductibility. A change in the 
period  of  deductibility  would  not  affect  the  ETR  but  would  accelerate  the 
payment to the taxing authority to an earlier period.

Net deferred tax liability associated with the unrecognized tax benefit amounts 
and related NOLs and tax credits carryforwards were $24 million and $13 
million at Dec. 31, 2018 and Dec 31, 2017, respectively. 

As the IRS Appeals and federal and state audits progress and other state 
audits resume, it is reasonably possible that the amount of unrecognized tax 
benefit could decrease up to approximately $28 million in the next 12 months.

ARAM is a method to flow back excess deferred taxes to customers.

ARAM has been deferred when regulatory treatment has not been established. As Xcel 
Energy received direction from its regulatory commissions regarding the return of excess 
deferred taxes to customers, the ARAM deferral was reversed. This resulted in a reduction 
to tax expense with a corresponding reduction to revenue.

Other Equity Awards — Xcel Energy Inc.’s Board of Directors has granted 
equity awards under the Xcel Energy Inc. Long-Term Incentive Plan and the 
Omnibus Incentive Plan. These plans include various vesting conditions and 
performance goals. At the end of the restricted period, such grants will be 
awarded if the vesting conditions and/or performance goals are met. 

Certain employees are granted equity awards with a portion subject only to 
service conditions, and the other portion subject to performance conditions. 
A total of 0.3 million time-based equity shares subject only to service conditions 
were granted annually in 2018, 2017 and 2016, respectively. 

The performance conditions for a portion of the awards granted from 2016 to 
2018 are based on relative TSR and environmental goals. Equity awards with 
performance  conditions  will  be  settled  or  forfeited  after  three  years,  with 
payouts ranging from zero to 200 percent depending on achievement.

8.  Share-Based Compensation

Incentive Plans Including Share-Based Compensation — Xcel Energy Inc. 
has three incentive plans that include share-based payment elements. Plans 
and authorized equity shares for awards: 

• 

• 

• 

Omnibus Incentive Plan - 7.0 million shares;

Long-Term Incentive Plan - 8.3 million shares; and,

Executive Annual Incentive Award Plan - 1.2 million shares.

Restricted  Stock  —  The  Executive  Annual  Incentive  Award  Plan  and 
Omnibus Incentive Plan allow certain employees to elect to receive shares of 
common or restricted stock. Restricted stock is treated as an equity award 
and vests and settles in equal annual installments over a three-year period. 
Restricted stock has a fair value equal to the market trading price of Xcel 
Energy Inc.’s stock at the grant date.

59

 
 
 
 
Stock  Equivalent  Units  —  Non-employee  members  of  Xcel  Energy  Inc. 
Board of Directors may elect to receive their annual equity grant as stock 
equivalent units in lieu of common stock. Each unit’s value is equal to one 
share of Xcel Energy Inc. common stock. The annual equity grant is vested 
as of the date of each member’s election to the Board of Directors; there is 
no further service or other condition.  Directors may also elect to receive their 
cash fees as stock equivalent units in lieu of cash. Stock equivalent units are 
payable as a distribution of common stock upon a director’s termination of 
service.

TSR Liability Awards — Xcel Energy Inc.’s Board of Directors has granted 
TSR  liability  awards  under  the  Long-Term  Incentive  Plan  and  Omnibus 
Incentive Plan. The plans allow Xcel Energy to attach various performance 
goals  to  the  awards  granted.  The  liability  awards  have  been  historically 
dependent on relative TSR measured over a three-year period. Xcel Energy 
Inc.’s TSR is compared to a 22-member utilities peer group for 2016 - 2018 
awards. Potential payouts of the awards range from zero to 200%.

TSR liability awards of $8 million were settled in cash in 2018. 

Share-Based  Compensation  Expense  —  Vesting  of  employee  equity 
awards is typically predicated on the achievement of a TSR or environmental 
measures target, other than for restricted stock. Additionally, approximately 
0.3 million of equity award units were granted annually in 2016 - 2018, with 
vesting  subject  only  to  service  conditions  of  three  years.  Generally  these 
instruments  are  considered  to  be  equity  awards  as  the  award  settlement 
determination (shares or cash) is made by Xcel Energy, not the participants. 
In addition, these awards have not been previously settled in cash and Xcel 
Energy plans to continue electing share settlement. Grant date fair value of 
equity awards is expensed over the service period.

TSR liability awards have been historically settled partially in cash, and do 
not qualify as equity awards, but rather are accounted for as liabilities. As 
liability awards, the fair value on which ratable expense is based, as employees 
vest in their rights to those awards, is remeasured each period based on the 
current stock price and performance achievement, and final expense is based 
on the market value of the shares on the date the award is settled.

Basic  EPS  was  computed  by  dividing  the  earnings  available  to  common 
shareholders by the weighted average number of common shares outstanding 
during  the  period.  Diluted  EPS  was  computed  by  dividing  the  earnings 
available to common shareholders by the diluted weighted average number 
of common shares outstanding during the period. Diluted EPS reflects the 
potential dilution that could occur if securities or other agreements to issue 
common stock (i.e., common stock equivalents) were settled. The weighted 
average number of potentially dilutive shares outstanding used to calculate 
diluted EPS is calculated using the treasury stock method.

Common  Stock  Equivalents  —  Xcel  Energy  Inc.  has  common  stock 
equivalents related to forward equity agreements and certain equity awards 
in  share-based  compensation  arrangements.  Common  stock  equivalents 
include commitments to issue common stock related to time based equity 
compensation awards. 

Stock equivalent units granted to Xcel Energy Inc.’s Board of Directors are 
included in common shares outstanding upon grant date as there is no further 
service,  performance  or  market  condition  associated  with  these  awards. 
Restricted stock issued to employees under the Xcel Energy Inc. Executive 
Annual Incentive Award Plan is included in common shares outstanding when 
granted.

Share-based  compensation  arrangements  for  which  there  is  currently  no 
dilutive impact to EPS include the following:

• 

• 

Equity awards subject to a performance condition; included in common 
shares outstanding when all necessary conditions for settlement have 
been satisfied by the end of the reporting period; and,

Liability awards subject to a performance condition; any portions settled 
in shares are included in common shares outstanding upon settlement.

Diluted common shares outstanding included common stock equivalents of 
0.5 million, 0.6 million and 0.7 million shares for 2018, 2017 and 2016.

10.  Fair Value of Financial Assets and Liabilities

Fair Value Measurements

Accounting guidance for fair value measurements and disclosures provides 
a single definition of fair value and requires disclosures about assets and 
liabilities measured at fair value. A hierarchical framework for disclosing the 
observability of the inputs utilized in measuring assets and liabilities at fair 
value is established by this guidance. 

• 

Level 1 — Quoted prices are available in active markets for identical 
assets or liabilities as of the reporting date. The types of assets and 
liabilities  included  in  Level  1  are  highly  liquid  and  actively  traded 
instruments with quoted prices.

• 

• 

Level 2 — Pricing inputs are other than quoted prices in active markets, 
but are either directly or indirectly observable as of the reporting date. 
The types of assets and liabilities included in Level 2 are typically either 
comparable  to  actively  traded  securities  or  contracts,  or  priced  with 
models using highly observable inputs.

Level 3 — Significant inputs to pricing have little or no observability as 
of the reporting date. The types of assets and liabilities included in Level 
3  are  those  valued  with  models  requiring  significant  management 
judgment or estimation.

Non-trading  monthly  FTR  settlements  are  included  in  fuel  and  purchased 
energy  cost  recovery  mechanisms  as  applicable  in  each  jurisdiction,  and 
therefore changes in the fair value of the yet to be settled portions of most 
FTRs  are  deferred  as  a  regulatory  asset  or  liability.  Given  this  regulatory 
treatment  and  the  limited  magnitude  of  FTRs  relative  to  the  electric  utility 
operations  of  NSP-Minnesota  and  SPS,  the  numerous  unobservable 
quantitative  inputs  pertinent  to  the  value  of  FTRs  are  insignificant  to  the 
consolidated financial statements of Xcel Energy.

Non-Derivative Fair Value Measurements

Specific valuation methods include:

Cash equivalents — The fair values of cash equivalents are generally based 
on cost plus accrued interest; money market funds are measured using quoted 
NAV.

Investments in equity securities and other funds — Equity securities are valued 
using quoted prices in active markets. The fair values for commingled funds 
are measured using NAVs. The investments in commingled funds may be 
redeemed  for  NAV  with  proper  notice.  Private  equity  commingled  fund 
investments require approval of the fund for any unscheduled redemption, 
and such redemptions may be approved or denied by the fund at its sole 
discretion.  Unscheduled  distributions  from  real  estate  commingled  funds 
investments may be redeemed with proper notice, however, withdrawals may 
be delayed or discounted as a result of fund illiquidity. 

Investments in debt securities — Fair values for debt securities are determined 
by a third party pricing service using recent trades and observable spreads 
from benchmark interest rates for similar securities.

Interest rate derivatives — Fair values of interest rate derivatives are based 
on broker quotes that utilize current market interest rate forecasts.

Commodity  derivatives  —  Methods  used  to  measure  the  fair  value  of 
commodity  derivative  forwards  and  options  utilize  forward  prices  and 
volatilities, as well as pricing adjustments for specific delivery locations, and 
are generally assigned a Level 2 classification. When contractual settlements 
relate to inactive delivery locations or extend to periods beyond those readily 
observable on active exchanges or quoted by brokers, the significance of the 
use of less observable forecasts of forward prices and volatilities on a valuation 
is evaluated and may result in Level 3 classification.

Electric  commodity  derivatives  held  by  NSP-Minnesota  and  SPS  include 
transmission congestion instruments, generally referred to as FTRs. FTRs 
purchased from a RTO are financial instruments that entitle or obligate the 
holder to monthly revenues or charges based on transmission congestion 
across a given transmission path. The value of an FTR is derived from, and 
designed to offset, the cost of transmission congestion. In addition to overall 
transmission load, congestion is also influenced by the operating schedules 
of  power  plants  and  the  consumption  of  electricity  pertinent  to  a  given 
transmission path. Unplanned plant outages, scheduled plant maintenance, 
changes in the relative costs of fuels used in generation, weather and overall 
changes in demand for electricity can each impact the operating schedules 
of the power plants on the transmission grid and the value of an FTR. 

If forecasted costs of electric transmission congestion increase or decrease 
for a given FTR path, the value of that particular FTR instrument will likewise 
increase or decrease. Given the limited observability of important inputs to 
the  value  of  FTRs  between  auction  processes,  including  expected  plant 
operating  schedules  and  retail  and  wholesale  demand, 
fair  value 
measurements for FTRs have been assigned a Level 3. 

The NRC requires NSP-Minnesota to maintain a portfolio of investments to 
fund the costs of decommissioning its nuclear generating plants. Assets of 
the nuclear decommissioning fund are legally restricted for the purpose of 
decommissioning these facilities. The fund contains cash equivalents, debt 
securities, equity securities and other investments. NSP-Minnesota uses the 
MPUC approved asset allocation for the escrow and investment targets by 
asset class for both the escrow and qualified trust.

NSP-Minnesota recognizes the costs of funding the decommissioning over 
the lives of the nuclear plants, assuming rate recovery of all costs. Realized 
and unrealized gains on fund investments over the life of the fund are deferred 
as an offset of NSP-Minnesota’s regulatory asset for nuclear decommissioning 
costs.  Consequently,  any  realized  and  unrealized  gains  and  losses  on 
securities in the nuclear decommissioning fund are deferred as a component 
of the regulatory asset.

Unrealized gains for the nuclear decommissioning fund were $450 million and 
$560 million as of Dec. 31, 2018 and 2017, respectively, and unrealized losses 
were $45 million and $7 million as of Dec. 31, 2018 and 2017, respectively.

Derivative Fair Value Measurements

Xcel Energy enters into derivative instruments, including forward contracts, 
futures,  swaps  and  options,  for  trading  purposes  and  to  manage  risk  in 
connection with changes in interest rates, utility commodity prices and vehicle 
fuel prices.

Interest Rate Derivatives — Xcel Energy enters into various instruments that 
effectively fix the interest payments on certain floating rate debt obligations 
or effectively fix the yield or price on a specified benchmark interest rate for 
an  anticipated  debt  issuance  for  a  specific  period.  These  derivative 
instruments  are  generally  designated  as  cash  flow  hedges  for  accounting 
purposes.

As  of  Dec.  31,  2018,  accumulated  other  comprehensive  losses  related  to 
interest  rate  derivatives  included  $3  million  of  net  losses  expected  to  be 
reclassified  into  earnings  during  the  next  12  months  as  the  hedged 
transactions impact earnings.

As of Dec 31, 2018, Xcel Energy had unsettled interest rate swaps outstanding 
with a notional amount of $300 million. These interest rate derivatives were 
designated as hedges, and as such, changes in fair value are recorded to 
other comprehensive income. 

Wholesale  and  Commodity  Trading  Risk  —  Xcel  Energy  Inc.’s  utility 
subsidiaries  conduct  various  wholesale  and  commodity  trading  activities, 
including the purchase and sale of electric capacity, energy, energy-related 
instruments and natural gas-related instruments, including derivatives. Xcel 
Energy is allowed to conduct these activities within guidelines and limitations 
as approved by its risk management committee, comprised of management 
personnel not directly involved in activities governed by this policy.

Commodity Derivatives — Xcel Energy enters into derivative instruments 
to manage variability of future cash flows from changes in commodity prices 
in its electric and natural gas operations, as well as for trading purposes.  This 
could  include  the  purchase  or  sale  of  energy  or  energy-related  products, 
natural gas to generate electric energy, natural gas for resale, FTRs, vehicle 
fuel and weather derivatives.

As of Dec. 31, 2018, Xcel Energy had no vehicle fuel contracts designated 
as cash flow hedges. Xcel Energy may enter into derivative instruments that 
mitigate commodity price risk on behalf of electric and natural gas customers, 
but may not be designated as qualifying hedging transactions. Changes in 
the fair value of non-trading commodity derivative instruments are recorded 
in other comprehensive income or deferred as a regulatory asset or liability.  
The classification as a regulatory asset or liability is based on commission 
approved regulatory recovery mechanisms. Immaterial amounts to income 
related to the ineffectiveness of cash flow hedges were recorded for the years 
ended Dec. 31, 2018 and 2017.

As of Dec. 31, 2018, there were no net gains related to commodity derivative 
cash  flow  hedges  recorded  as  a  component  of  accumulated  other 
comprehensive losses or related amounts expected to be reclassified into 
earnings during the next 12 months.  

Xcel Energy enters into commodity derivative instruments for trading purposes 
not directly related to commodity price risks associated with serving its electric 
and natural gas customers. Changes in the fair value of these commodity 
derivatives  are  recorded  in  electric  operating  revenues,  net  of  amounts 
credited to customers under margin-sharing mechanisms.

Notional  amounts  for  options  are  included  on  a  gross  basis,  but  are  weighted  for  the 
probability of exercise.

Consideration  of  Credit  Risk  and  Concentrations  —  Xcel  Energy 
continuously monitors the creditworthiness of counterparties to its interest rate 
derivatives  and  commodity  derivative  contracts  prior  to  settlement,  and 
assesses each counterparty’s ability to perform on the transactions set forth 
in  the  contracts.  Impact  of  credit  risk  was  immaterial  to  the  fair  value  of 
unsettled  commodity  derivatives  presented  in  the  consolidated  balance 
sheets.

Xcel Energy’s utility subsidiaries’ most significant concentrations of credit risk 
with particular entities or industries are contracts with counterparties to their 
wholesale, trading and non-trading commodity activities. 

62

As of Dec. 31, 2018, six of Xcel Energy’s 10 most significant counterparties 
for these activities, comprising $96 million or 43% of this credit exposure, had 
investment  grade  credit  ratings  from  Standard  &  Poor’s,  Moody’s  or  Fitch 
Ratings.  Three  of  the  10  most  significant  counterparties,  comprising  $20 
million or 9% of this credit exposure, were not rated by these external agencies, 
but based on Xcel Energy’s internal analysis, had credit quality consistent 
with investment grade. One of these significant counterparties, comprising 
$12 million or 5% of this credit exposure, had credit quality less than investment 
grade, based on Xcel Energy’s internal analysis. Eight of these significant 
counterparties are municipal or cooperative electric entities or other utilities.

and  vehicle  fuel  cash  flow  hedges  on  Xcel  Energy’s  accumulated  other

Amounts recorded to interest charges.

Amounts recorded to electric operating revenues. Portions of these gains and losses are 
subject  to  sharing  with  electric  customers  through  margin-sharing  mechanisms  and 
deducted from gross revenue, as appropriate.

Amounts recorded to electric fuel and purchased power. These derivative settlement gains 
and losses are shared with electric customers through fuel and purchased energy cost-
recovery mechanisms, and reclassified out of income as regulatory assets or liabilities, as 
appropriate.

Amounts for the year ended Dec. 31, 2018 included $1 million of settlement losses on 
derivatives entered to mitigate natural gas price risk for electric generation recorded to 
electric fuel and purchased power, subject to cost-recovery mechanisms and reclassified 
to a regulatory asset, as appropriate. Such gains and losses for the years ended Dec. 31, 
2017 and 2016 were immaterial. Remaining settlement losses for the years ended Dec. 
31, 2018, 2017 and 2016 related to natural gas operations and were recorded to cost of 
natural gas sold and transported. These losses are subject to cost-recovery mechanisms 
and reclassified out of income to a regulatory asset, as appropriate. 

Xcel Energy had no derivative instruments designated as fair value hedges 
during the years ended Dec. 31, 2018, 2017 and 2016.

Credit Related Contingent Features — Contract provisions for derivative instruments that the utility subsidiaries enter, including those accounted for as normal 
purchase-normal sale contracts and therefore not reflected on the consolidated balance sheets, may require the posting of collateral or settlement of the 
contracts for various reasons, including if the applicable utility subsidiary’s credit ratings are downgraded below its investment grade credit rating by any of the 
major credit rating agencies, or for cross default contractual provisions if there was a failure under other financing arrangements related to payment terms or 
other covenants.  As of Dec. 31, 2018 and 2017, there were no derivative instruments in a liability position with such underlying contract provisions.

Certain derivative instruments are also subject to contract provisions that contain adequate assurance clauses. These provisions allow counterparties to seek 
performance assurance, including cash collateral, in the event that a given utility subsidiary’s ability to fulfill its contractual obligations is reasonably expected 
to be impaired. Xcel Energy had no collateral posted related to adequate assurance clauses in derivative contracts as of Dec. 31, 2018 and 2017.

Xcel Energy nets derivative instruments and related collateral in its consolidated balance sheet when supported by a legally enforceable master netting agreement, and all derivative instruments 
and related collateral amounts were subject to master netting agreements as of Dec. 31, 2018 and 2017. At Dec. 31, 2018 and 2017, derivative assets and liabilities include $32 million and $0 
million of obligations to return cash collateral, respectively. At Dec. 31, 2018 and 2017, derivative assets and liabilities include rights to reclaim cash collateral of $15 million and $3 million, 
respectively. Counterparty netting excludes settlement receivables and payables and non-derivative amounts that may be subject to the same master netting agreements.
During 2006, Xcel Energy qualified these contracts under the normal purchase exception. Based on this qualification, the contracts are no longer adjusted to fair value and the previous carrying 
value of these contracts will be amortized over the remaining contract lives along with the offsetting regulatory assets and liabilities.

Xcel Energy has a contributory health and welfare benefit plan that provides 
health care and death benefits to certain Xcel Energy retirees.

• 

• 

• 

NSP-Minnesota  and  NSP-Wisconsin  discontinued  subsidizing  health 
care benefits for non-bargaining employees retiring after 1998 and for 
bargaining employees who retired after 1999.

Xcel  Energy  discontinued  subsidizing  health  care  benefits 
for 
nonbargaining employees of the former NCE who retired after June 30, 
2003.

Xcel  Energy  discontinued  health  care  benefits  for  SPS  bargaining 
employees hired after Jan. 1, 2012. 

Xcel Energy bases the investment-return assumption on expected long-term 
performance for each of the asset classes in its pension and postretirement 
health care portfolios. For pension assets, Xcel Energy considers the historical 
returns achieved by its asset portfolio over the past 20 years or longer period, 
as well as long-term projected return levels. 

Pension cost determination assumes a forecasted mix of investment types 
over the long-term.

• 

• 

• 

• 

Investment returns in 2018 were below the assumed level of 6.87%;

Investment returns in 2017 were above the assumed level of 6.87%;

Investment returns in 2016 were below the assumed level of 6.87%; and,

In 2019, Xcel Energy’s expected investment-return assumption is 6.87%.

Pension plan and postretirement benefit assets are invested in a portfolio 
according to Xcel Energy’s return, liquidity and diversification objectives to 
provide a source of funding for plan obligations and minimize contributions to 
the  plan,  within  appropriate  levels  of  risk.  The  principal  mechanism  for 
achieving these objectives is the asset allocation given the long-term risk, 
return, correlation and liquidity characteristics of each particular asset class. 
There were no significant concentrations of risk in any industry, index, or entity. 
Market volatility can impact even well-diversified portfolios and significantly 
affect the return levels achieved by the assets in any year.

State agencies also have issued guidelines to the funding of postretirement 
benefit costs. SPS is required to fund postretirement benefit costs for Texas 
and  New  Mexico  amounts  collected  in  rates.  PSCo  is  required  to  fund 
postretirement benefit costs in irrevocable external trusts that are dedicated 
to the payment of these postretirement benefits. These assets are invested 
in a manner consistent with the investment strategy for the pension plan.

Xcel  Energy’s  ongoing  investment  strategy  is  based  on  plan-specific 
investment recommendations that seek to minimize potential investment and 
interest rate risk as a plan’s funded status increases over time. The investment 
recommendations result in a greater percentage of long-duration fixed income 
securities being allocated to specific plans having relatively higher funded 
status ratios and a greater percentage of growth assets being allocated to 
plans having relatively lower funded status ratios.

Fair value of Xcel Energy’s long-term debt is estimated based on recent trades

Fair value estimates are based on information available to management as 
of Dec. 31, 2018 and 2017, and given the observability of the inputs, fair values 
presented for long-term debt were assigned as Level 2.

11.    Benefit Plans and Other Postretirement Benefits

Pension and Postretirement Health Care Benefits

Xcel Energy has several noncontributory, defined benefit pension plans that 
cover almost all employees. Generally, benefits are based on a combination 
of years of service and average pay. Xcel Energy’s policy is to fully fund into 
an  external  trust  the  actuarially  determined  pension  costs  subject  to  the 
limitations of applicable employee benefit and tax laws.

In addition to the qualified pension plans, Xcel Energy maintains a SERP and 
a nonqualified pension plan. The SERP is maintained for certain executives 
that were participants in the plan in 2008, when the SERP was closed to new 
participants.  The  nonqualified  pension  plan  provides  benefits 
for 
compensation that is in excess of the limits applicable to the qualified pension 
plans, with distributions funded by Xcel Energy’s consolidated operating cash 
flows. Obligations of the SERP and nonqualified plan as of Dec. 31, 2018 and 
2017 were $33 million and $37 million, respectively. Xcel Energy recognized 
net benefit cost for the SERP and nonqualified plans of $4 million in 2018 and 
$5 million in 2017. 

In 2016, Xcel Energy established rabbi trusts to provide partial funding for 
future  distributions  of  the  SERP  and  its  deferred  compensation  plan, 
supplemented by Xcel Energy’s consolidated operating cash flows.

A settlement charge is required when the amount of all lump-sum distributions during the year is greater than the sum of the service and interest cost components of the annual net periodic 
pension cost. In 2018 and 2017, as a result of lump-sum distributions during the 2018 and 2017 plan years, Xcel Energy recorded a total pension settlement charge of $91 million in 2018 and 
$81 million in 2017, the majority of which was not recognized due to the effects of regulation. A total of $11 million and $8 million was recorded in the consolidated statements of  income in 
2018 and 2017, respectively.

Plan Amendments — The Xcel Energy Pension Plan and Xcel Energy Inc. 
Nonbargaining  Pension  Plan  (South)  were  amended  in  2017  to  reduce 
supplemental benefits for non-bargaining participants as well as to allow the 
transfer  of  a  portion  of  non-qualified  pension  obligations  into  the  qualified 
plans. In 2016, the Xcel Energy Pension Plan was amended to change the 
discount  rate  basis  for  lump-sum  conversion  to  annuity  participants  and 
annuity conversion to lump-sum participants. Annual credits contributed to the 
PSCo Bargaining Plan retirement spending account also increased. 

In 2018 and 2017, there were no plan amendments made which affected the 
postretirement benefit obligation.

Defined Contribution Plans

Xcel Energy maintains 401(k) and other defined contribution plans that cover 
most employees. Total expense to these plans was approximately $38 million
in 2018, $37 million in 2017 and $36 million in 2016.

Multiemployer Plans

NSP-Minnesota  and  NSP-Wisconsin  each  contribute  to  several  union 
multiemployer pension and other postretirement benefit plans, none of which 
are individually significant. These plans provide pension and postretirement 
health care benefits to certain union employees who may perform services 
for multiple employers and do not participate in the NSP-Minnesota and NSP-
Wisconsin  sponsored  pension  and  postretirement  health  care  plans. 
Contributing to these types of plans creates risk that differs from providing 
benefits under NSP-Minnesota and NSP-Wisconsin sponsored plans, in that 
if another participating employer ceases to contribute to a multiemployer plan, 
additional unfunded obligations may need to be funded over time by remaining 
participating employers.

12.  Commitments and Contingencies

Legal 

Xcel Energy is involved in various litigation matters that are being defended 
and handled in the ordinary course of business. Assessing whether a loss is 
probable or a reasonable possibility, and whether the loss or a range of loss 
is  estimable,  often  involves  complex  judgments  regarding  future  events. 
Management maintains accruals for losses that are probable of being incurred 
and subject to reasonable estimation. Management may be unable to estimate 
an  amount  or  range  of  a  reasonably  possible  loss  in  certain  situations, 
including when (1) the damages sought are indeterminate, (2) the proceedings 
are in the early stages, or (3) the matters involve novel or unsettled legal 
theories. In such cases, there is considerable uncertainty regarding the timing 
or ultimate resolution of such matters, including a possible eventual loss. For 
current proceedings not specifically reported herein, management does not 
anticipate the ultimate liabilities, if any, arising from such current proceedings 
would have a material effect on Xcel Energy’s financial statements. Unless 
otherwise required by GAAP, legal fees are expensed as incurred. 

Gas  Trading  Litigation  —  e  prime  is  a  wholly  owned  subsidiary  of  Xcel 
Energy. e prime was in the business of natural gas trading and marketing but 
has not engaged in natural gas trading or marketing activities since 2003.   
Multiple  lawsuits  seeking  monetary  damages  were  commenced  against  e 
prime and its affiliates, including Xcel Energy,  between 2003 and 2009 alleging 
fraud and anticompetitive activities in conspiring to restrain the trade of natural 
gas and manipulate natural gas prices. Cases were all consolidated in the 
U.S. District Court in Nevada. 

In the fourth quarter of 2018, four cases were settled. Two cases remain active 
which include an MDL matter consisting of a Colorado class (Breckenridge) 
and a Wisconsin class (Arandell Corp.).

Breckenridge/Colorado — Case has been remanded to the MDL panel, and 
is expected to be referred back to the U.S. District Court in Colorado. Xcel 
Energy has concluded that a loss is remote.

Arandell Corp.  — In November 2017, the U.S. District Court in Nevada granted 
summary judgment against two plaintiffs in the Arandell Corp. case in favor 
of Xcel Energy and NSP-Wisconsin, leaving only three individual plaintiffs 
remaining  in  the  litigation.  In  addition,  the  plaintiffs’  motions  for  class 
certification and remand back to originating courts were denied in March 2017. 

Plaintiffs have asked the lower court to remand the cases back to the court 
where the actions were originally filed anticipating class certification. A hearing 
date has not been set. Xcel Energy has concluded that a loss is remote.

Line  Extension  Disputes  —  In  December  2015,  the  DRC  filed  a  lawsuit 
seeking monetary damages in the Denver District Court, stating PSCo failed 
to  award  proper  allowances  and  refunds  for  line  extensions  to  new 
developments pursuant to the terms of electric and gas service agreements. 
The dispute involves claims by over fifty developers. In February 2018, the 
Colorado Supreme Court denied DRC’s petition to appeal the Denver District 
Court’s dismissal of the lawsuit, effectively terminating this litigation.  However, 
in January 2018, DRC filed a new lawsuit in Boulder County District Court, 
asserting  a  single  claim  that  PSCo  was  required  to  file  its  line  extension 
agreements with the CPUC but failed to do so. 

This claim is substantially similar to the arguments previously raised by DRC. 
PSCo filed a motion to dismiss this claim, which was granted in May 2018.  
DRC subsequently filed an appeal to the Colorado Court of Appeals with its 
opening brief in January 2019 and PSCo filed its answer brief in February 
2019.  It is uncertain when a decision will be rendered.

PSCo has concluded that a loss is remote with respect to both of these matters 
as the service agreements were developed to implement CPUC approved 
tariffs  and  PSCo  has  complied  with  the  tariff  provisions.  If  a  loss  were 
sustained,  PSCo  believes  it  would  be  allowed  to  recover  costs  through 
traditional regulatory mechanisms. Amount or range in dispute is presently 
unknown and no accrual has been recorded for this matter.

Rate Matters 

NSP-Minnesota — Sherco — In NSP-Minnesota’s 2013 fuel reconciliation 
filing, the MPUC made recovery of replacement power costs associated with 
the 2011 incident at its Sherco Unit 3 plant provisional and subject to further 
review  following  conclusion  of  litigation  commenced  by  NSP-Minnesota, 
SMMPA (Co-owner of Sherco Unit 3) and insurance companies against GE.

In 2018, NSP-Minnesota and SMMPA reached a settlement with GE. NSP-
Minnesota has notified the MPUC of its proposal to refund the GE settlement 
proceeds back to customers through the FCA.

The insurance providers continued their litigation against GE and the case 
went to trial. In 2018, GE prevailed in the lawsuit with the insurance companies, 
however, the jury found comparable fault, finding that GE was 52% and NSP-
Minnesota was 48% at fault. At that point in the litigation, NSP-Minnesota was 
no longer involved in the case and was not present to make arguments about 
its role in the event. The specific issue leading to the fault apportionment was 
also not before the jury and not relevant to the outcome of the trial.

In January 2019, the DOC recommended that NSP-Minnesota refund $20 
million of previously recovered purchased power costs to its customers, based 
on  the  jury’s  apportionment  of  fault.  The  OAG  recommended  the  MPUC 
withhold any decision until the underlying litigation by the insurance providers 
(currently under appeal) is concluded. The DOC subsequently filed comments 
agreeing with the OAG’s recommendation to withhold a decision pending the 
outcome of any appeals.

NSP-Minnesota filed reply comments arguing that the DOC recommendations 
are without merit and that it acted prudently in operating the plant and its 
settlement with GE was reasonable.

MISO ROE Complaints — In November 2013 and February 2015, customers 
filed  complaints  against  MISO  TOs  including  NSP-Minnesota  and  NSP-
Wisconsin. The first complaint argued for a reduction in the base ROE in MISO 
transmission formula rates from 12.38% to 9.15%, and removal of ROE adders 
(including  those  for  RTO  membership).  The  second  complaint  sought  to 
reduce base ROE from 12.38% to 8.67%. 

69

In September 2016, the FERC issued an order granting a 10.32% base ROE 
(10.82% with the RTO adder) effective for the first complaint period of Nov. 
12, 2013 to Feb. 11, 2015 and subsequent to the date of the order. The D.C. 
Circuit subsequently vacated and remanded FERC Opinion No. 531, which 
had established the ROE methodology on which the September 2016 FERC 
order was based.

In October 2018, the FERC issued a NETO base ROE order that 
addressed the D.C. Circuit’s actions on Opinion No. 531. Under a new 
proposed two step ROE approach, the FERC has indicated an intention to 
dismiss an ROE complaint if the existing ROE falls within the range of just 
and reasonable ROEs based on equal weighting of the DCF, CAPM, and 
Expected Earnings models. The FERC proposes that if necessary, it would 
then set a new ROE by averaging the results of these models plus a Risk 
Premium model.

With respect to the MISO TOs, the FERC subsequently made preliminary 
determinations in a November 2018 order that the MISO base ROE in 
effect for the first complaint period (12.38%) was outside the range of 
reasonableness, and should be reduced. The FERC indicated its 
preliminary analysis using the new ROE approach resulted in a base ROE 
of 10.28% for the first compliant period, compared to the previously ordered 
base ROE of 10.32%. A procedural schedule has been set for the first half 
of 2019, with the FERC expected to act no earlier than the second half of 
2019. NSP-Minnesota has recognized a current refund liability consistent 
with its best estimate of the final ROE.

SPP OATT Upgrade Costs — Under the SPP OATT, costs of transmission 
upgrades may be recovered from other SPP customers whose transmission 
service depends on capacity enabled by the upgrade. The SPP OATT has 
allowed SPP to charge for these upgrades since 2008, but SPP had not been 
charging its customers for these upgrades. In 2016, the FERC granted SPP’s 
request to recover these previously unbilled charges. SPP subsequently billed 
SPS approximately $13 million for these charges.

In July 2018, SPS’ appeal to the D.C. Circuit over the FERC rulings granting 
SPP the right to recover these previously unbilled charges was remanded to 
the FERC. Assessment of these charges (from 2008 - 2016) is being reviewed 
by the FERC, which is expected to rule in the first quarter of 2019.

In October 2017, SPS filed a separate complaint against SPP asserting that 
SPP has assessed upgrade charges to SPS in violation of the SPP OATT. 
The FERC has granted a rehearing for further consideration in May 2018. The 
timing of FERC action on the SPS rehearing is uncertain. If SPS’ complaint 
results in additional charges or refunds, it will seek to recover or refund the 
differential in future rate proceedings.

Environmental

New  and  changing  federal  and  state  environmental  mandates  can  create 
financial liabilities for Xcel Energy, which are normally recovered through the 
regulated rate process. 

Site Remediation — Various federal and state environmental laws impose 
liability where hazardous substances or other regulated materials have been 
released to the environment. Xcel Energy Inc.’s subsidiaries may sometimes 
pay all or a portion of the cost to remediate sites where past activities of their 
predecessors  or  other  parties  have  caused  environmental  contamination. 
Environmental contingencies could arise from various situations, including 
sites of former MGPs; and third-party sites, such as landfills, for which one or 
more of Xcel Energy Inc.’s subsidiaries are alleged to have sent wastes to 
that site.

MGP Sites

Ashland MGP Site — NSP-Wisconsin was named a responsible party for 
contamination  at  the Ashland/Northern  States  Power  Lakefront  Superfund 
Site (the Site) in Ashland, Wisconsin. Remediation and restoration activities 
are anticipated to be completed in 2019 and groundwater treatment activities 
will continue for many years.

Current cost estimate for remediation of the entire site is approximately $192 
million, of which approximately $165 million has been spent. As of Dec. 31, 
2018 and 2017, NSP-Wisconsin recorded a total liability of $27 million and 
$30 million, respectively, for the entire site.

NSP-Wisconsin has deferred the unrecovered portion of the estimated Site 
remediation costs as a regulatory asset. The PSCW has authorized NSP-
Wisconsin rate recovery for all remediation costs incurred at the Site. In 2012, 
the  PSCW  agreed  to  allow  NSP-Wisconsin  to  pre-collect  certain  costs,  to 
amortize costs over a 10-year period and to apply a 3% carrying cost to the 
unamortized regulatory asset.

MGP, Landfill or Disposal Sites — Xcel Energy is currently investigating or 
remediating  twelve  MGP,  landfill  or  other  disposal  sites  across  its  service 
territories,  in  addition  to  the Ashland  MGP  Site,  and  these  activities  will 
continue through at least 2019. Xcel Energy accrued $9 million as of Dec. 31, 
2018  and  $19  million  as  of  Dec.  31,  2017  for  these  sites.  There  may  be 
insurance recovery and/or recovery from other potentially responsible parties, 
offsetting a portion of the costs incurred.

Environmental Requirements — Water and Waste

Coal Ash Regulation — Xcel Energy’s operations are subject to federal and 
state  laws  that  impose  requirements  for  handling,  storage,  treatment  and 
disposal of solid waste. In 2015, the EPA published the CCR Rule. Litigation 
was brought challenging the rule in the D.C. Circuit.

Under the CCR Rule, utilities are required to complete groundwater sampling 
around  their  CCR  landfills  and  surface  impoundments.  Xcel  Energy  has 
identified at least two sites in Colorado where SSLs exist in the groundwater 
near landfills and/or impoundments. Xcel Energy has completed removal of 
CCR from these impoundments and plans to close these landfills. By the end 
of 2019, only nine of Xcel Energy’s regulated ash units are expected to be in 
operation. Xcel Energy is conducting additional groundwater sampling and 
will  evaluate  whether  corrective  action  is  required  at  any  CCR  landfills  or 
surface impoundments. 

Until Xcel Energy completes its assessment, it is uncertain what impact, if 
any, there will be on the operations, financial condition or cash flows. In August 
2018, the D.C. Circuit ruled that the EPA cannot allow utilities to continue to 
use  unlined  impoundments  (including  clay  lined  impoundments)  for  the 
storage or disposal of coal ash. Litigation is ongoing regarding the deadline 
for closing or retrofitting these impoundments. The decision will require Xcel 
Energy  to  expedite  closure  of  one  impoundment  in  Minnesota  (see ARO 
removal costs below) and will require construction of a new impoundment, 
which is estimated to cost $6 million.

Federal CWA WOTUS Rule — In 2015, the EPA and Corps published a final 
rule that significantly broadened the scope of waters under the CWA that are 
subject to federal jurisdiction, referred to as “WOTUS”. The Rule has been 
subject to significant litigation and is currently stayed in a portion of the country. 
Xcel  Energy  cannot  estimate  potential  impacts  until  the  legal  and 
administrative processes are finalized, but expects costs will be recoverable 
through regulatory mechanisms.

Federal CWA ELG — In 2015, the EPA issued a final ELG rule for power 
plants that discharge treated effluent to surface waters as well as utility-owned 
landfills that receive CCRs. In 2017, the EPA delayed the compliance date for 
flue gas desulfurization wastewater and bottom ash transport until November 
2020.  After  2020,  Xcel  Energy  estimates  that  ELG  compliance  will  cost 
approximately $12 million to complete. The EPA, however, is conducting a 
rulemaking  process  to  potentially  revise  the  effluent  limitations  and 
pretreatment standards, which may impact compliance costs. Xcel Energy 
anticipates  these  costs  will  be  fully  recoverable  through  regulatory 
mechanisms.

Federal CWA Section 316(b) — The federal CWA requires the EPA to regulate 
cooling water intake structures to assure that these structures reflect the best 
technology available for minimizing impingement and entrainment of aquatic 
species. Xcel Energy estimates the likely cost for complying with impingement 
and entrainment requirements is approximately $40 million, to be incurred 
between 2019 and 2028. Xcel Energy believes six NSP-Minnesota plants and 
two  NSP-Wisconsin  plants  could  be  required  by  state  regulators  to  make 
improvements to reduce impingement and entrainment. The exact total cost 
of the impingement and entrainment improvements is uncertain, but could be 
up to approximately $200 million. Xcel Energy anticipates these costs will be 
fully recoverable through regulatory mechanisms.

Environmental Requirements — Air

Regional Haze Rules — The regional haze program requires SO2, NOX and 
PM emission controls at power plants to reduce visibility impairment in national 
parks and wilderness areas. The program includes BART and reasonable 
further progress. 

The requirements of the first regional haze plans developed by Minnesota 
and Colorado have been approved and implemented. Texas’ first regional 
haze plan has undergone federal review as described below.

BART  Determination  for  Texas:  The  EPA  has  issued  a  revised  final  rule 
adopting a BART alternative Texas only SO2 trading program that applies to 
all Harrington and Tolk units. Under the trading program, SPS expects the 
allowance allocations to be sufficient for SO2 emissions. The anticipated costs 
of compliance are not expected to have a material impact; and SPS believes 
that compliance costs would be recoverable through regulatory mechanisms.

Several  parties  have  challenged  whether  the  final  rule  issued  by  the  EPA 
should be considered to have met the requirements imposed in a Consent 
Decree entered by the United States District Court for the District of Columbia 
that established deadlines for the EPA to take final action on state regional 
haze plan submissions. The court has required status reports from the parties 
while the EPA works on the reconsideration rulemaking.

In December 2017, the National Parks Conservation Association, Sierra Club, 
and Environmental Defense Fund appealed the EPA’s 2017 final BART rule 
to the Fifth Circuit and filed a petition for administrative reconsideration. In 
January 2018, the court granted SPS’ motion to intervene in the Fifth Circuit 
litigation in support of the EPA’s final rule. The court has held the litigation in 
abeyance while the EPA decided whether to reconsider the rule. In August 
2018, the EPA started a reconsideration rulemaking. It is not known when the 
EPA will make a final decision on this proposal.

Reasonable Progress Rule: In 2016, the EPA adopted a final rule establishing 
a  federal  implementation  plan  for  reasonable  further  progress  under  the 
regional haze program for the state of Texas. The rule imposes SO2 emission 
limitations that would require the installation of dry scrubbers on Tolk Units 1 
and  2,  with  compliance  required  by  February  2021.  Investment  costs 
associated with dry scrubbers could be $600 million. SPS appealed the EPA’s 
decision and obtained a stay of the final rule.

Amounts settled related to asbestos abatement, closure of ash containment facilities, and

In 2017, AROs were revised for changes in timing and estimates of cash flows. Nuclear 
AROs  decreased  due  to  updated  assumptions.  Changes  in  gas  transmission  and 
distribution AROs were primarily related to increased labor costs.

Indeterminate AROs — Other plants or buildings may contain asbestos due 
to  the  age  of  many  of  Xcel  Energy’s  facilities,  but  no  confirmation  or 
measurement of the cost of removal could be determined as of Dec. 31, 2018. 
Therefore, an ARO was not recorded for these facilities. 

Removal Costs — Xcel Energy records a regulatory liability for the plant 
removal costs of its utility subsidiaries that are recovered currently in rates. 
Removal costs have accumulated based on varying rates as authorized by 
the appropriate regulatory entities. The utility subsidiaries have estimated the 
amount of removal costs accumulated through historic depreciation expense 
based on current factors used in the existing depreciation rates.

Nuclear Related

Nuclear Insurance — NSP-Minnesota’s public liability for claims from any 
nuclear  incident  is  limited  to  $14.1  billion  under  the  Price-Anderson 
amendment  to  the Atomic  Energy Act.  NSP-Minnesota  has  secured  $450 
million of coverage for its public liability exposure with a pool of insurance 
companies.  The  remaining  $13.6  billion  of  exposure  is  funded  by  the 
Secondary Financial Protection Program, available from assessments by the 
federal government. 

In  March  2017,  the  Fifth  Circuit  remanded  the  rule  to  the  EPA  for 
reconsideration, leaving the stay in effect. In a future rulemaking, the EPA will 
address whether SO2 emission reductions beyond those required in the BART 
alternative  rule  are  needed  at  Tolk  under  the  “reasonable  progress” 
requirements.  The  EPA  has  not  announced  a  schedule  for  acting  on  the 
remanded rule. 

Implementation of the NAAQS for SO2 — The EPA has designated all areas 
near SPS’ generating plants as attaining the SO2 NAAQS with an exception. 
The  EPA  issued  final  designations  which  found  the  area  near  the  SPS 
Harrington plant as “unclassifiable.” The area near the Harrington plant is to 
be monitored for three years and a final designation is expected to be made 
by December 2020. 

If the area near the Harrington plant is designated nonattainment in 2020, the 
TCEQ will need to develop an implementation plan, designed to achieve the 
NAAQS  by  2025.  The  TCEQ  could  require  additional  SO2  controls  at 
Harrington as part of such a plan. Xcel Energy cannot evaluate the impacts 
until the final designation is made and any required state plans are developed. 
Xcel Energy believes that should SO2 control systems be required for a plant, 
compliance costs or the costs of alternative cost-effective generation will be 
recoverable through regulatory mechanisms and therefore does not expect a 
material impact on results of operations, financial condition or cash flows. 

AROs — AROs have been recorded for Xcel Energy’s assets. For nuclear 
assets,  the  ARO  is  associated  with  the  decommissioning  of  the  NSP-
Minnesota nuclear generating plants, Monticello and PI.

Aggregate fair value of NSP-Minnesota’s legally restricted assets, for funding 
future nuclear decommissioning, was $2.1 billion for 2018 and 2017.

In 2018, AROs were revised for changes in timing and estimates of cash flows. Changes 
in gas transmission and distribution AROs were primarily related to increased gas line 
mileage and number of services, which were more than offset by increased discount rates. 
Changes in electric distribution AROs primarily related to increased labor costs.

Decommissioning expense does not include depreciation of the capitalized nuclear asset 
retirement costs.

Decommissioning expenses in 2018, 2017 and 2016 include Minnesota’s retail jurisdiction 
annual funding requirement of approximately $14 million.

The 2014 nuclear decommissioning filing, approved in 2015, was used for  
regulatory presentation in 2018, 2017 and 2016. The 2017 filing, effective Jan. 
1, 2019, has been approved by the MPUC. 

Leases — Xcel Energy has three leases accounted for as capital leases. The 
assets and liabilities of a capital lease are recorded at the lower of fair market 
value of the leased asset or the present value of future lease payments and 
are amortized over the term of the contract.

WYCO is a joint venture with CIG to develop and lease natural gas pipeline, 
storage and compression facilities. Xcel Energy Inc. has a 50% ownership 
interest in WYCO. WYCO leases its facilities to CIG, and CIG operates the 
facilities, providing natural gas storage and transportation services to PSCo 
under separate service agreements.

NSP-Minnesota is subject to assessments of up to $138 million per reactor-
incident for each of its three licensed reactors, for public liability arising from 
a nuclear incident at any licensed nuclear facility in the United States. The 
maximum funding requirement is $21 million per reactor-incident during any 
one year. Maximum assessments are subject to inflation adjustments by the 
NRC  and  state  premium  taxes.  The  NRC’s  last  adjustment  was  effective 
November 2018.

insurance 

NSP-Minnesota  purchases 
for  property  damage  and  site 
decontamination cleanup costs from NEIL and EMANI. The coverage limits 
are $2.3 billion for each of NSP-Minnesota’s two nuclear plant sites. NEIL also 
provides  business  interruption  insurance  coverage,  including  the  cost  of 
replacement power during prolonged accidental outages of nuclear generating 
units. Premiums are expensed over the policy term.

All  companies  insured  with  NEIL  are  subject  to  retroactive  premium 
adjustments if losses exceed accumulated reserve funds. Capital has been 
accumulated in the reserve funds of NEIL and EMANI to the extent that NSP-
Minnesota would have no exposure for retroactive premium assessments in 
case of a single incident under the business interruption and the property 
damage  insurance  coverage.  NSP-Minnesota  could  be  subject  to  annual 
maximum assessments of approximately $18 million for business interruption 
insurance and $39 million for property damage insurance if losses exceed 
accumulated reserve funds.

Nuclear  Fuel  Disposal  —  NSP-Minnesota  is  responsible  for  temporarily 
storing spent nuclear fuel from its nuclear plants. The DOE is responsible for 
permanently storing spent fuel from U.S. nuclear plants, but no such facility 
is yet available. 

NSP-Minnesota owns temporary on-site storage facilities for spent fuel at its 
Monticello and PI nuclear plants, which consist of storage pools and dry cask 
facilities. The Monticello dry-cask storage facility currently stores all 30 of the 
authorized canisters. The PI dry-cask storage facility currently stores 44 of 
the  64  authorized  casks.  Monticello’s  future  spent  fuel  will  continue  to  be 
placed  in  its  spent  fuel  pool.  The  decommissioning  plan  addresses  the 
disposition of spent fuel at the end of the licensed life.

Regulatory  Plant  Decommissioning  Recovery  —  Decommissioning 
activities for NSP-Minnesota’s nuclear facilities are planned to begin at the 
end  of  each  unit’s  operating  license  and  be  completed  by  2091.  NSP-
Minnesota’s current operating licenses allow continued use of its Monticello 
nuclear plant until 2030 and its PI nuclear plant until 2033 for Unit 1 and 2034 
for Unit 2.

Future  decommissioning  costs  of  nuclear  facilities  are  estimated  through 
triennial periodic studies that assess the costs and timing of planned nuclear 
decommissioning activities for each unit.

Obligation for decommissioning is expected to be funded 100% by the external 
decommissioning  trust  fund.  This  cost  study  assumes  the  external 
decommissioning fund will earn an after-tax return between 5.23%  and 6.30%  
Realized and unrealized gains on fund investments are deferred as an offset 
of  NSP-Minnesota’s  regulatory  asset  for  nuclear  decommissioning  costs. 
Decommissioning costs are quantified in 2014 dollars. Escalation rates are 
4.36% for plant removal activities and 3.36% for fuel management and site 
restoration activities.  

NSP-Minnesota  has  accumulated  $2.1  billion  of  assets  held  in  external 
decommissioning trusts in 2018. The following table summarizes the funded 
status of NSP-Minnesota’s decommissioning obligation. Xcel Energy believes 
future decommissioning costs will continue to be recovered in customer rates. 
The following amounts were prepared on a regulatory basis and not directly 
recorded in the financial statements (ARO).

PSCo accounts for its Totem natural gas storage service arrangement with 
CIG as a capital lease. Xcel Energy Inc. eliminates 50% of the capital lease 
obligation related to WYCO in the consolidated balance sheet along with an 
equal amount of Xcel Energy Inc.’s equity investment in WYCO.

PSCo records amortization for its capital lease assets as electric fuel and 
purchased  power  and  cost  of  natural  gas  sold  and  transported  on  the 
consolidated statements of income.

Amounts do not include PPAs accounted for as executory contracts.

PPA operating leases contractually expire through 2034.

Excludes certain amounts related to Xcel Energy’s 50% ownership interest in WYCO.

Non-Lease PPAs — NSP Minnesota, PSCo and SPS have entered into PPAs 
with other utilities and energy suppliers with expiration dates through 2039 
for purchased power to meet system load and energy requirements, meet 
operating reserve obligations and as part of wholesale and commodity trading 
activities. In general, these agreements provide for energy payments, based 
on actual energy delivered and capacity payments. Certain PPAs accounted 
for as executory contracts contain minimum energy purchase commitments. 

73

Capacity and energy payments are contingent on the IPPs meeting contract 
obligations,  including  plant  availability  requirements.  Certain  contractual 
payments  are  adjusted  based  on  market  indices.  The  effects  of  price 
adjustments on our financial results are mitigated through purchased energy 
cost recovery mechanisms.

Included in electric fuel and purchased power expenses for PPAs accounted 
for as executory contracts were payments for capacity of $131 million, $168 
million and $191 million in 2018, 2017 and 2016, respectively. 

At Dec. 31, 2018, the estimated future payments for capacity and energy that 
the utility subsidiaries of Xcel Energy are obligated to purchase pursuant to 
these executory contracts, subject to availability, were as follows:

Fuel  Contracts  —  Xcel  Energy  has  entered  into  various  long-term 
commitments for the purchase and delivery of a significant portion of its coal, 
nuclear fuel and natural gas requirements. These contracts expire between 
2019 and 2060. Xcel Energy is required to pay additional amounts depending 
on actual quantities shipped under these agreements.

VIEs 

PPAs  —  Under  certain  PPAs,  NSP-Minnesota,  PSCo  and  SPS  purchase 
power from IPPs for which the utility subsidiaries are required to reimburse 
fuel  costs,  or  to  participate  in  tolling  arrangements  under  which  the  utility 
subsidiaries procure the natural gas required to produce the energy that they 
purchase. Xcel Energy has determined that certain IPPs are VIEs. Xcel Energy 
is  not  subject  to  risk  of  loss  from  the  operations  of  these  entities,  and  no 
significant financial support is required other than contractual payments for 
energy and capacity.

In  addition,  certain  solar  PPAs  provide  an  option  to  purchase  emission 
allowances or sharing provisions related to production credits generated by 
the solar facility under contract. These specific PPAs create a variable interest 
in the IPP.

Xcel Energy evaluated each of these VIEs for possible consolidation, including 
review of qualitative factors such as the length and terms of the contract, 
control over O&M, control over dispatch of electricity, historical and estimated 
future fuel and electricity prices, and financing activities. 

Xcel Energy concluded that these entities are not required to be consolidated 
in its consolidated financial statements because it does not have the power 
to direct the activities that most significantly impact the entities’ economic 
performance. Xcel Energy’s utility subsidiaries had approximately 3,770 MW 
and 3,537 MW of capacity under long-term PPAs at Dec. 31, 2018 and 2017, 
respectively, with entities that have been determined to be VIEs. Agreements 
have expiration dates through 2041.

Fuel Contracts — SPS purchases all of its coal requirements for its Harrington 
and Tolk plants from TUCO under contracts that will expire in December 2022. 
TUCO arranges for the purchase, receiving, transporting, unloading, handling, 
crushing, weighing and delivery of coal to meet SPS’ requirements. TUCO is 
responsible for negotiating and administering contracts with coal suppliers, 
transporters and handlers.

SPS has not provided any significant financial support to TUCO, other than 
contractual payments for delivered coal. However, the fuel contracts create a 
variable interest in TUCO due to SPS’ reimbursement of fuel procurement 
costs. SPS has determined that TUCO is a VIE. SPS has concluded that it is 
not the primary beneficiary of TUCO because SPS does not have the power 
to  direct  the  activities  that  most  significantly  impact  TUCO’s  economic 
performance.

Low-Income Housing Limited Partnerships — Eloigne and NSP-Wisconsin 
have entered into limited partnerships for the construction and operation of 
affordable rental housing developments which qualify for low-income housing 
tax credits. Xcel Energy Inc. has determined Eloigne and NSP-Wisconsin’s 
low-income  housing  partnerships  to  be  VIEs  primarily  due  to  contractual 
arrangements within each limited partnership that establish sharing of ongoing 
voting control and profits and losses that does not align with the partners’ 
proportional equity ownership. Eloigne and NSP-Wisconsin have the power 
to direct the activities that most significantly impact these entities’ economic 
performance.  Therefore,  Xcel  Energy  Inc.  consolidates  these  limited 
partnerships in its consolidated financial statements. Xcel Energy’s risk of loss 
for these partnerships is limited to its capital contributions, adjusted for any 
distributions and its share of undistributed profits and losses; no significant 
additional financial  support has  been, or is required to be provided to the 
limited partnerships by Eloigne or NSP-Wisconsin.

Amounts  reflected  in  Xcel  Energy’s  consolidated  balance  sheets  for  the 
Eloigne and NSP-Wisconsin low-income housing limited partnerships:

Asset and capital expenditure information is not provided for Xcel Energy’s 
reportable segments. As an integrated electric and natural gas utility, Xcel 
Energy operates significant assets that are not dedicated to a specific business 
segment. Reporting assets and capital expenditures by business segment 
would require arbitrary and potentially misleading allocations which may not 
necessarily reflect the assets that would be required for the operation of the 
business segments on a stand-alone basis.

Certain costs, such as common depreciation, common O&M expenses and 
interest expense are allocated based on cost causation allocators across each 
segment.  In  addition,  a  general  allocator  is  used  for  certain  general  and 
administrative expenses, including office supplies, rent, property insurance 
and general advertising.

14.  Segments and Related Information

Regulated electric utility operating results of NSP-Minnesota, NSP-Wisconsin, 
PSCo and SPS, as well as the regulated natural gas utility operating results 
of  NSP-Minnesota,  NSP-Wisconsin  and  PSCo  are  each  separately  and 
regularly  reviewed  by  Xcel  Energy’s  chief  operating  decision  maker.  Xcel 
Energy evaluates performance by each utility subsidiary based on profit or 
loss generated from the product or service provided. These segments are 
managed  separately  because  the  revenue  streams  are  dependent  upon 
regulated rate recovery, which is separately determined for each segment.

Xcel Energy has the following reportable segments: 

• 

• 

• 

Regulated  Electric  - The  regulated  electric  utility  segment  generates, 
transmits and distributes electricity in Minnesota, Wisconsin, Michigan, 
North  Dakota,  South  Dakota,  Colorado,  Texas  and  New  Mexico.  In 
addition, this segment includes sales for resale and provides wholesale 
transmission  service  to  various  entities  in  the  United  States.  The 
regulated electric utility segment also includes wholesale commodity and 
trading operations.

Regulated  Natural  Gas  -  The  regulated  natural  gas  utility  segment 
transports,  stores  and  distributes  natural  gas  primarily  in  portions  of 
Minnesota, Wisconsin, North Dakota, Michigan and Colorado.

All  Other  -  Operating  segments  with  revenues  below  the  necessary 
quantitative thresholds are included in this category. Those segments 
primarily include steam revenue, appliance repair services, non-utility 
real estate activities, revenues associated with processing solid waste 
into refuse-derived fuel and investments in rental housing projects that 
qualify for low-income housing tax credits.

Xcel Energy had equity investments in unconsolidated subsidiaries of $141 
million and $140 million as of Dec. 31, 2018 and 2017, respectively, included 
in the natural gas utility and all other segments.

summarized, and reported within the time periods specified in SEC rules and

information required to be disclosed is accumulated and communicated to 
management, including the chief executive officer and chief financial officer, 
allowing timely decisions regarding required disclosure. As of Dec. 31, 2018, 
based  on  an  evaluation  carried  out  under  the  supervision  and  with  the 
participation  of  Xcel  Energy’s  management,  including  the  chief  executive

and the procedures, the chief executive officer and chief financial officer have 
concluded  that  Xcel  Energy’s  disclosure  controls  and  procedures  were 
effective.

occurred during the most recent fiscal quarter that has materially affected, or 
is reasonably likely to materially affect, Xcel Energy’s internal control over 
financial  reporting.  Xcel  Energy  maintains  internal  control  over  financial 
reporting  to  provide  reasonable  assurance  regarding  the  reliability  of  the

NOTES TO CONDENSED FINANCIAL STATEMENTS

Incorporated  by  reference  are  Xcel  Energy’s  consolidated  statements  of 
common  stockholders’  equity  and  other  comprehensive  income  in  Part II, 
Item 8.

Basis of Presentation — The condensed financial information of Xcel Energy 
Inc. is presented to comply with Rule 12-04 of Regulation S-X. Xcel Energy 
Inc.’s investments in subsidiaries are presented under the equity method of 
accounting. Under this method, the assets and liabilities of subsidiaries are 
not  consolidated.  The  investments  in  net  assets  of  the  subsidiaries  are 
recorded  in  the  balance  sheets.  The  income  from  operations  of  the 
subsidiaries is reported on a net basis as equity in income of subsidiaries.

As a holding company with no business operations, Xcel Energy Inc.’s assets 
consist primarily of investments in its utility subsidiaries. Xcel Energy Inc.’s 
material cash inflows are only from dividends and other payments received 
from its utility subsidiaries and the proceeds raised from the sale of debt and 
equity securities. The ability of its utility subsidiaries to make dividend and 
other payments is subject to the availability of funds after taking into account 
their  respective  funding  requirements,  the  terms  of  their  respective 
indebtedness, the regulations of the FERC under the Federal Power Act, and 
applicable  state  laws.  Management  does  not  expect  maintaining  these 
requirements to have an impact on Xcel Energy Inc.’s ability to pay dividends 
at the current level in the foreseeable future. Each of its utility subsidiaries, 
however, is legally distinct and has no obligation, contingent or otherwise, to 
make funds available to Xcel Energy Inc.

Guarantees and Indemnifications

Xcel Energy Inc. provides guarantees and bond indemnities under specified 
agreements or transactions, which guarantee payment or performance. Xcel 
Energy Inc.’s exposure is based upon the net liability of the relevant subsidiary 
under the specified agreements or transactions. Most of the guarantees and 
bond indemnities issued by Xcel Energy Inc. limit the exposure to a maximum 
stated amount. As of Dec. 31, 2018 and 2017, Xcel Energy Inc. had no assets 
held as collateral related to guarantees, bond indemnities and indemnification 
agreements.

Guarantees and bond indemnities issued and outstanding as of Dec. 31, 
2018:

The terms of this guarantee expires in 2021 and 2023 when the associated leases expire.

The term of this guarantee expires the earlier of 2024 or full repayment of the loan.
The surety bonds primarily relate to workers compensation benefits and utility projects. 
The  workers  compensation  bonds  are  renewed  annually  and  the  project  based  bonds 
expire in conjunction with the completion of the related projects.

Nonperformance and/or nonpayment.
Per the indemnity agreement between Xcel Energy Inc. and the various surety companies, 
surety companies have the discretion to demand that collateral be posted. 

Due  to  the  magnitude  of  projects  associated  with  the  surety  bonds,  the  total  current 
exposure  of  this  indemnification  cannot  be  determined.  Xcel  Energy  Inc.  believes  the 
exposure to be significantly less than the total amount of the outstanding bonds.
