2022 Annual Report

March 2023

Dear ALLETE shareholders,

These are incredibly exciting times in the energy industry and at ALLETE, 
and as we move into 2023, we are executing our “sustainability in action” 
strategy in a very big way. For the past two years, ALLETE ranked first 
among U.S.-based investor-owned utilities for investment in renewable 
energy based on market capitalization. We are leading the way to a 
sustainable clean-energy future, while working hard to ensure we get this 
transformation right for our customers, our communities, and the climate 
to make our world a better place.

A significant achievement in 2022 was ALLETE’s acquisition of New Energy Equity, one of the nation’s 
leading and most respected distributed solar developers. As we approach New Energy Equity’s 
one-year anniversary as part of the ALLETE family of companies, the value of the talented team and 
profitable business is notable, with contributions to earnings and a project pipeline that have exceeded 
our expectations.

Minnesota Power is wrapping up work on three solar projects that will add more than 20 megawatts 
of clean energy to its system. The three projects are part of an approximately $40 million investment 
approved by the Minnesota Public Utilities Commission (MPUC) that also is designed to boost 
northeastern Minnesota’s economic recovery from the COVID-19 pandemic. These renewable energy 
projects, completed with local labor and locally manufactured panels, are just one example of how 
ALLETE is putting sustainability into action.

It has never been clearer that transmission investments will be critical to meeting clean-energy goals 
and transforming the electric grid. And, transmission plays an important role in ALLETE’s strategy. 
For example, in July 2022, Minnesota Power and Great River Energy announced plans to build an 
approximately 150-mile transmission line from northern Minnesota to central Minnesota that will 
support grid reliability in the Upper Midwest. 

In January 2023, ALLETE and Grid United announced our intent to jointly develop the North Plains 
Connector, a new, approximately 385-mile high-voltage direct-current (HVDC) transmission line from 
central North Dakota to Colstrip, Montana. It will be the nation’s first transmission connection between 
three regional U.S. electric energy markets—the Midcontinent Independent System Operator, the 
Western Interconnection and the Southwest Power Pool—to increase resiliency and reliability across a 
vast area with diverse weather patterns. This is exactly the type of project and vision that is needed to 
ensure the successful transformation of our nation’s electric grid.

As ALLETE and our companies continue to lead the way to a sustainable clean-energy future, 
alignment with state regulators and policymakers is critical.

In November 2022, the MPUC approved Minnesota Power’s 15-year Integrated Resource Plan, the 
regulatory roadmap for the company’s EnergyForward vision to provide 100% carbon-free energy by 
2050 while maintaining safe, reliable and affordable electric serve to customers. Building on an extensive 
two-year process that involved discussions with customers and a wide variety of stakeholders, 
Minnesota Power reached a joint agreement with stakeholders including clean-energy organizations, 
labor groups, and local communities that host the company’s last remaining coal-fired power plant. 

The MPUC approved all of the elements of the joint agreement, including the addition of up to 700 
megawatts of wind and solar power and a significant investment in battery storage by 2030 to support 
the addition of renewable energy.

In early February this year, a new Minnesota law was enacted requiring state utilities to deliver carbon-
free energy by 2040, 10 years earlier than the company vision laid out by Minnesota Power. The new 
law comes with some off-ramps to protect energy reliability and affordability, but it will require a 
shift in how we plan for and develop the clean-energy economy to meet a goal that is now a decade 
earlier.  And, constructive regulatory outcomes will be critical to our success.

There is a lot of work ahead of us—reaching clean-energy goals will require thoughtful planning to 
ensure we keep reliability and affordability at the forefront. Achieving this ambitious goal will require 
leveraging new technologies through accelerated Minnesota Power investments. At the same time, we 
expect the new Minnesota law to create opportunities for our other ALLETE companies as demand for 
wind and solar generation is expected to grow. 

As we navigate the complex and ever-changing road to our nation’s carbon-free future, it is 
important to remember that ALLETE and our companies have long been leaders in the clean-energy 
transformation, and we have momentum on our side. Minnesota Power was the first Minnesota utility 
to reach 50% renewable energy and has a solid record of exceeding state conservation objectives and 
state renewable energy goals ahead of deadlines. 

While we serve our customers with excellence and provide exciting opportunities for our employees, 
we also take great pride in creating value for our shareholders. In February, the ALLETE Board of 
Directors approved an increased dividend of over 4%. ALLETE has continued to pay an attractive 
dividend, while strategically positioning all of our businesses for sustainable growth over the long term.

I could not be more proud of our talented, experienced and innovative ALLETE team, and I am 
excited about our future as we continue to put sustainability into action with tremendous growth 
opportunities in front of us. As part of our journey toward a carbon-free energy future, we know that 
we have a responsibility to get this transition right for the climate, our customers, our communities and 
our investors—all without leaving anyone behind. To learn more about how we at ALLETE embrace 
sustainability in all its forms, please see our Corporate Sustainability Report at www.allete.com.

As always, thank you for your interest and investment in ALLETE.

Overview.

Part I

ALLETE is a leader in the nation’s clean-energy transformation. Our businesses and dedicated employees deliver sustainable 
energy solutions that mitigate climate change, build thriving communities, help customers reach their sustainability goals and 
drive  value  for  shareholders.  In  2020,  ALLETE’s  largest  business,  Minnesota  Power,  reached  a  milestone  of  providing 
50  percent  renewable  energy  to  its  retail  and  municipal  customers  in  Minnesota,  and  the  Company  envisions  delivering 
100 percent carbon-free energy to customers by 2050—a vision grounded in a steadfast commitment to climate, customers and 
community through its EnergyForward strategy. ALLETE Clean Energy, our second-largest business, is positioned at the heart 
of  society’s  clean-energy  transformation  and  owns,  operates  or  is  developing  more  than  1,300  megawatts  of  wind  energy 
generation across eight states – helping some of the largest companies in the country reduce their carbon footprint.

Minnesota Power’s latest IRP, approved by the MPUC in an order dated January 9, 2023, outlines its clean-energy transition 
plans  through  2035.  These  plans  include  expanding  its  renewable  energy  supply  to  70  percent  by  2030,  achieving  coal-free 
operations at its facilities by 2035, and investing in a resilient and flexible transmission and distribution grid. Minnesota Power 
has also set a target to achieve an 80 percent reduction in carbon emissions by 2035 compared to 2005 levels. As part of these 
plans, Minnesota Power anticipates adding up to 700 MW of new wind and solar energy resources, and ceasing coal operations 
at Boswell Units 3 and 4 by 2030 and 2035, respectively. Minnesota Power’s plans recognize that advances in technology will 
play a significant role in completing its transition to carbon-free energy supply, reliably and affordably.

In recent years, Minnesota Power has transformed its energy supply from more than a 95 percent reliance on coal to become a 
leader in the nation’s clean-energy transformation. Since 2013, the company has closed or converted seven of its nine coal-fired 
units and added nearly 900 megawatts of renewable energy sources. Additionally, Minnesota Power has been a leader in energy 
conservation, surpassing the state’s conservation goals each year for the past decade. 

On February 7, 2023, the Minnesota Governor signed into law legislation that updates the state’s renewable energy standard 
and requires Minnesota electric utilities to source retail sales with 100 percent carbon-free energy by 2040. The Company is 
evaluating  the  law  to  identify  challenges  and  opportunities  it  could  present.  (See  Regulated  Operations  –  Minnesota 
Legislation.)

ALLETE  is  also  committed  to  earning  a  financial  return  that  rewards  our  shareholders,  allows  for  reinvestment  in  our 
businesses,  and  sustains  growth.  ALLETE  is  predominately  a  regulated  utility  through  Minnesota  Power,  SWL&P,  and  an 
investment  in  ATC.  ALLETE’s  strategy  is  to  remain  predominately  a  regulated  utility  while  investing  in  ALLETE  Clean 
Energy and New Energy and its Corporate and Other businesses to complement its regulated businesses, balance exposure to 
the utility’s industrial customers, and provide potential long-term earnings growth.

Regulated  Operations  includes  our  regulated  utilities,  Minnesota  Power  and  SWL&P,  as  well  as  our  investment  in  ATC,  a 
Wisconsin-based  regulated  utility  that  owns  and  maintains  electric  transmission  assets  in  portions  of  Wisconsin,  Michigan, 
Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 
150,000  retail  customers.  Minnesota  Power  also  has  14  non-affiliated  municipal  customers  in  Minnesota.  SWL&P  is  a 
Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and 
water  service  in  northwestern  Wisconsin  to  approximately  15,000  electric  customers,  13,000  natural  gas  customers  and 
10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state 
and federal regulatory authorities. (See Note 4. Regulatory Matters.)

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean 
Energy currently owns and operates, in seven states, more than 1,200 MW of nameplate capacity wind energy generation with a 
majority contracted under PSAs of various durations. In addition, ALLETE Clean Energy engages in the development of wind 
energy facilities to operate under long-term PSAs or for sale to others upon completion. ALLETE Clean Energy currently has 
approximately 100 MW of wind energy facilities under contract to be sold to others.

Industrial Customers. In 2022, industrial customers represented 52 percent of total regulated utility kWh sales. Our industrial 
customers are primarily in the taconite mining, paper, pulp and secondary wood products, and pipeline industries.

The COVID-19 pandemic and related governmental responses led to a disruption of economic activity. This disruption resulted 
in reduced sales and revenue from industrial customers in 2020 as many industrial customers operated at reduced levels or were 
temporarily closed or idled during 2020. Sales to our industrial customers in 2021 were similar to levels prior to the COVID-19 
pandemic. In 2022 Cliffs decided to idle all production at its Northshore mine until at least April 2023.

Six taconite facilities served by Minnesota Power made up approximately 85 percent of 2021 iron ore pellet production in the 
U.S. according to data from the Minnesota Department of Revenue 2022 Mining Tax Guide. These taconite facilities are owned 
by Cliffs and USS Corporation. (See Large Power Customer Contracts.) Sales to taconite customers represented 4,713 million 
kWh, or 70 percent of total industrial customer kWh sales in 2022. Taconite, an iron-bearing rock of relatively low iron content, 
is abundantly available in northern Minnesota and an important domestic source of raw material for the steel industry. Taconite 
processing plants use large quantities of electric power to grind the iron-bearing rock, and agglomerate and pelletize the iron 
particles into taconite pellets. 

Minnesota  Power’s  taconite  customers  are  capable  of  producing  approximately  41  million  tons  of  taconite  pellets  annually. 
Taconite  pellets  produced  in  Minnesota  are  primarily  shipped  to  North  American  steel  making  facilities  that  are  part  of  the 
integrated  steel  industry,  which  continue  to  lead  the  world  in  environmental  performance  among  steelmaking  countries. 
According  to  the  U.S.  Department  of  Energy,  steel  production  in  the  U.S.  is  the  most  energy  efficient  of  any  major  steel 
producing country. Steel produced from these North American facilities is used primarily in the manufacture of automobiles, 
appliances, tubular applications for all industries, and in the construction industry. Steel is also a critical component of the clean 
energy  transformation  underway  today.  The  demand  for  more  renewable  energy  and  the  need  for  additional  infrastructure  to 
transport  green  energy  from  the  point  of  generation  to  the  end  user  both  require  steel.  Historically,  less  than  10  percent  of 
Minnesota taconite production has been exported outside of North America.

There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American 
Iron and Steel Institute, an association of North American steel producers, reported that U.S. raw steel production operated at 
approximately 78 percent of capacity in 2022 (82 percent in 2021 and 68 percent in 2020). The World Steel Association, an 
association  of  steel  producers,  national  and  regional  steel  industry  associations,  and  steel  research  institutes  representing 
approximately 85 percent of world steel production, projected U.S. steel consumption in 2023 will increase by approximately 
2 percent compared to 2022.

* Preliminary data from the Minnesota Department of Revenue.

Minnesota Power’s taconite customers may experience annual variations in production levels due to such factors as economic 
conditions,  short-term  demand  changes  or  maintenance  outages.  We  estimate  that  a  one  million  ton  change  in  Minnesota 
Power’s taconite customers’ production would impact our annual earnings per share by approximately $0.04, net of expected 
power  marketing  sales  at  current  prices.  Changes  in  wholesale  electric  prices  or  customer  contractual  demand  nominations 
could  impact  this  estimate.  Minnesota  Power  proactively  sells  power  in  the  wholesale  power  markets  that  is  temporarily  not 
required by industrial customers to optimize the value of its generating facilities. Long-term reductions in taconite production or 
a permanent shut down of a taconite customer may lead Minnesota Power to file a general rate case to recover lost revenue.

In addition to serving the taconite industry, Minnesota Power serves a number of customers in the paper, pulp and secondary 
wood  products  industry,  which  represented  735  million  kWh,  or  11  percent  of  total  industrial  customer  kWh  sales  in  2022. 
Minnesota Power also has an agreement to provide steam for one paper and pulp customer for use in the customer’s operations. 
The  major  paper  and  pulp  mills  we  serve  reported  operating  at  similar  levels  in  2022  compared  to  2021.  Verso  Corporation 
indefinitely  idled  its  paper  mill  in  Duluth,  Minnesota,  which  it  subsequently  sold  to  ST  Paper  in  May  2021.  (See  Outlook  – 
Regulated Operations – Industrial Customers and Prospective Additional Load – Paper, Pulp and Secondary Wood Products – 
ST Paper.)

Large Power Customer Contracts. Minnesota Power had seven Large Power Customer contracts as of December 31, 2022, 
each  serving  requirements  of  10  MW  or  more  of  customer  load.  The  customers  as  of  December  31,  2022  consisted  of  six 
taconite facilities owned by Cliffs and USS Corporation as well as three paper and pulp mills. Certain facilities with common 
ownership are served under combined contracts.

REGULATED OPERATIONS (Continued)
Large Power Customer Contracts (Continued)

Large Power Customer contracts require Minnesota Power to have a certain amount of generating capacity available. In turn, 
each Large Power Customer is required to pay a minimum monthly demand charge that covers the fixed costs associated with 
having this capacity available to serve the customer, including a return on common equity. Most contracts allow customers to 
establish the level of megawatts subject to a demand charge on a three- to four-month basis and require that a portion of their 
megawatt  needs  be  committed  on  a  take-or-pay  basis  for  at  least  a  portion  of  the  term  of  the  agreement.  In  addition  to  the 
demand  charge,  each  Large  Power  Customer  is  billed  an  energy  charge  for  each  kWh  used  that  recovers  the  variable  costs 
incurred  in  generating  electricity.  Five  of  the  Large  Power  Customer  contracts  have  interruptible  service  which  provides  a 
discounted demand rate in exchange for the ability to interrupt the customers during system emergencies. Minnesota Power also 
provides  incremental  production  service  for  customer  demand  levels  above  the  contractual  take-or-pay  levels.  There  is  no 
demand  charge  for  this  service  and  energy  is  priced  at  an  increment  above  Minnesota  Power’s  cost.  Incremental  production 
service is interruptible.

All  contracts  with  Large  Power  Customers  continue  past  the  contract  termination  date  unless  the  required  advance  notice  of 
cancellation has been given. The required advance notice of cancellation varies from two to four years. Such contracts reduce 
the impact on earnings that otherwise would result from significant reductions in kWh sales to such customers. Large Power 
Customers are required to take all of their purchased electric service requirements from Minnesota Power for the duration of 
their  contracts.  The  rates  and  corresponding  revenue  associated  with  capacity  and  energy  provided  under  these  contracts  are 
subject  to  change  through  the  same  regulatory  process  governing  all  retail  electric  rates.  (See  Regulatory  Matters  –  Electric 
Rates.)

Minnesota  Power,  as  permitted  by  the  MPUC,  requires  its  taconite-producing  Large  Power  Customers  to  pay  weekly  for 
electric usage based on monthly energy usage estimates. These customers receive estimated bills or make weekly prepayments 
based  on  Minnesota  Power’s  estimate  of  the  customer’s  energy  usage,  forecasted  energy  prices  and  fuel  adjustment  clause 
estimates. Minnesota Power’s taconite-producing Large Power Customers have generally predictable energy usage on a week-
to-week basis and any differences that occur are trued-up the following month.

Residential  and  Commercial  Customers.  In  2022,  residential  and  commercial  customers  represented  20  percent  of  total 
regulated utility kWh sales. 

Municipal Customers. In 2022, municipal customers represented 4 percent of total regulated utility kWh sales. 

Minnesota  Power’s  wholesale  electric  contracts  with  14  non-affiliated  municipal  customers  in  Minnesota  have  termination 
dates ranging from 2029 through 2037, with a majority of contracts expiring in 2029. One of these wholesale contracts includes 
a termination clause requiring a three-year notice to terminate. (See Note 4. Regulatory Matters.)

Other  Power  Suppliers.  The  Company  also  enters  into  off-system  sales  with  Other  Power  Suppliers.  These  sales  are  at 
market-based prices into the MISO market on a daily basis or through bilateral agreements of various durations.

Our  PSAs  are  detailed  in  Note  9.  Commitments,  Guarantees  and  Contingencies,  with  additional  disclosure  provided  in  the 
following paragraphs.

Minnkota Power PSA. Minnesota Power has a PSA with Minnkota Power where Minnesota Power is selling a portion of its 
entitlement  from  Square  Butte  to  Minnkota  Power,  resulting  in  Minnkota  Power’s  net  entitlement  increasing  and  Minnesota 
Power’s  net  entitlement  decreasing  until  Minnesota  Power’s  share  is  eliminated  at  the  end  of  2025.  Of  Minnesota  Power’s 
50 percent output entitlement, it sold approximately 32 percent to Minnkota Power in 2022 (28 percent in 2021 and in 2020). 
Minnkota Power’s net entitlement increases to approximately 37 percent in 2023, 41 percent in 2024, 46 percent in 2025 and 
50 percent in 2026. (See Power Supply – Long-Term Purchased Power.) 

Silver Bay Power PSA. Minnesota Power has a PSA with Silver Bay Power through 2031 to supply the full energy requirements 
for Silver Bay Power. Silver Bay Power supplies approximately 90 MW of load to Northshore Mining, an affiliate of Silver Bay 
Power. 

Hibbing  Public  Utilities.  In  April  2022,  Minnesota  Power  entered  into  a  new  long-term  Power  Purchase  and  Market  Energy 
Service Agreement with Hibbing Public Utilities for the period of June 1, 2022, through May 31, 2027. The agreement replaced 
the previous wholesale electric contract between Hibbing Public Utilities and Minnesota Power.

Seasonality

The  operations  of  our  industrial  customers,  which  make  up  a  large  portion  of  our  electric  sales,  are  not  typically  subject  to 
significant  seasonal  variations.  (See  Electric  Sales  /  Customers.)  As  a  result,  Minnesota  Power  is  generally  not  subject  to 
significant seasonal fluctuations in electric sales; however, Minnesota Power and SWL&P electric and natural gas sales to other 
customers may be affected by seasonal differences in weather. In general, peak electric sales occur in the winter and summer 
months with fewer electric sales in the spring and fall months. Peak sales of natural gas generally occur in the winter months. 
Additionally, our regulated utilities have historically generated fewer sales and less revenue when weather conditions are milder 
in the winter and summer.

Power Supply

In  order  to  meet  its  customers’  electric  requirements,  Minnesota  Power  utilizes  a  mix  of  its  own  generation  and  purchased 
power. As of December 31, 2022, approximately 50 percent of Minnesota Power’s power supply for its retail and municipal 
customers  in  Minnesota  was  provided  by  renewable  energy  sources.  This  was  enabled  by  the  completion  of  the  250  MW 
Nobles  2  wind  energy  facility  in  December  2020  and  the  GNTL  in  June  2020,  which  is  used  to  deliver  250  MW  of 
hydroelectric  energy  from  Manitoba  Hydro.  Minnesota  Power’s  remaining  operating  coal-fired  facilities  are  Boswell  Units  3 
and 4, which Minnesota Power plans to cease coal operations at by 2030 and 2035, respectively. (See Regulatory Matters.) The 
following  table  reflects  Minnesota  Power’s  generating  capabilities  as  of  December  31,  2022,  and  total  electrical  supply  for 
2022. Minnesota Power had an annual net peak load of 1,556 MW on January 7, 2022.

Fuel. Minnesota Power purchases low-sulfur, sub-bituminous coal from the Powder River Basin region located in Montana and 
Wyoming.  Coal  consumption  in  2022  for  electric  generation  at  Minnesota  Power’s  coal-fired  generating  stations  was 
2.7  million  tons  (2.7  million  tons  in  2021;  2.2  million  tons  in  2020).  As  of  December  31,  2022,  Minnesota  Power  had  coal 
inventories  of  0.8  million  tons  (0.4  million  tons  as  of  December  31,  2021).  Minnesota  Power  has  coal  supply  agreements 
providing for the purchase of a significant portion of its coal requirements through December 2023. In 2023, Minnesota Power 
expects to obtain coal under these coal supply agreements and in the spot market. Minnesota Power continues to explore other 
future coal supply options and believes that adequate supplies of low-sulfur, sub-bituminous coal will continue to be available.

Minnesota  Power  also  has  coal  transportation  agreements  in  place  for  the  delivery  of  a  significant  portion  of  its  coal 
requirements through December 2024. The costs of fuel and related transportation costs for Minnesota Power’s generation are 
recoverable from Minnesota Power’s utility customers through the fuel adjustment clause.

Long-Term  Purchased  Power.  Minnesota  Power  has  contracts  to  purchase  capacity  and  energy  from  various  entities, 
including output from certain coal, wind, hydro and solar generating facilities. 

Our  PPAs  are  detailed  in  Note  9.  Commitments,  Guarantees  and  Contingencies,  with  additional  disclosure  provided  in  the 
following paragraph.

Square Butte PPA. Under the PPA with Square Butte that extends through 2026, Minnesota Power is entitled to 50 percent of 
the output of Square Butte’s 455 MW coal-fired generating unit. (See Note 9. Commitments, Guarantees and Contingencies.) 
BNI  Energy  mines  and  sells  lignite  coal  to  Square  Butte.  This  lignite  supply  is  sufficient  to  provide  fuel  for  the  anticipated 
useful  life  of  the  generating  unit.  Square  Butte’s  cost  of  lignite  consumed  in  2022  was  approximately  $2.05  per  MBtu 
($1.94 per MBtu in 2021; $1.75 per MBtu in 2020). (See Electric Sales / Customers – Minnkota Power PSA.)

Manitoba  Hydro.  Minnesota  Power  has  two  long-term  PPAs  with  Manitoba  Hydro.  The  first  PPA  provides  for  Minnesota 
Power to purchase 250 MW of capacity and energy from Manitoba Hydro through May 2035. The second PPA provides for 
Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro through June 2040. A third PPA, which expired 
in April 2022 was an energy-only agreement, which primarily consisted of surplus hydro energy on Manitoba Hydro’s system 
that was delivered to Minnesota Power on a non-firm basis. 

Transmission and Distribution

We  have  electric  transmission  and  distribution  lines  of  500  kV  (232  miles),  345  kV  (241  miles),  250  kV  (466  miles), 
230 kV (715 miles), 161 kV (43 miles), 138 kV (8 miles), 115 kV (1,376 miles) and less than 115 kV (6,416 miles). We own 
and operate 162 substations with a total capacity of 10,116 megavoltamperes. Some of our transmission and distribution lines 
interconnect with other utilities.

Great  Northern  Transmission  Line.  As  a  condition  of  the  250  MW  long-term  PPA  entered  into  with  Manitoba  Hydro, 
construction  of  additional  transmission  capacity  was  required.  As  a  result,  Minnesota  Power  constructed  the  GNTL,  an 
approximately  220-mile  500-kV  transmission  line  between  Manitoba  and  Minnesota’s  Iron  Range  that  was  proposed  by 
Minnesota  Power  and  Manitoba  Hydro  in  order  to  strengthen  the  electric  grid,  enhance  regional  reliability  and  promote  a 
greater  exchange  of  sustainable  energy.  In  June  2020,  Minnesota  Power  placed  the  GNTL  into  service  with  project  costs  of 
approximately $310 million incurred by Minnesota Power. Total project costs, including those costs contributed by a subsidiary 
of Manitoba Hydro, totaled approximately $660 million. The 250 MW PPA with Manitoba Hydro commenced when the GNTL 
was placed into service.

Our  wholly-owned  subsidiary,  ALLETE  Transmission  Holdings,  owns  approximately  8  percent  of  ATC,  a  Wisconsin-based 
utility  that  owns  and  maintains  electric  transmission  assets  in  portions  of  Wisconsin,  Michigan,  Minnesota  and  Illinois.  We 
account for our investment in ATC under the equity method of accounting. As of December 31, 2022, our equity investment in 
ATC was $165.4 million ($154.5 million as of December 31, 2021). (See Note 6. Equity Investments.) 

ATC’s authorized return on equity is 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional 
transmission organization, based on a 2020 FERC order which is subject to various outstanding legal challenges related to the 
return  on  equity  calculation  and  refund  period  ordered  by  the  FERC.  On  August  9,  2022,  the  U.S.  Court  of  Appeals  for  the 
District of Columbia Circuit vacated and remanded the 2020 FERC order back to the FERC. As a result of this decision, ATC 
recorded a reserve in the third quarter of 2022 for anticipated refunds to its customers for approximately $31 million of which 
our share was approximately $2.4 million pre-tax. We cannot predict the return on equity the FERC will ultimately authorize in 
the remanded proceeding.

In addition, the FERC issued a Notice of Proposed Rulemaking in April 2021 proposing to limit the 50 basis point incentive 
adder  for  participation  in  a  regional  transmission  organization  to  only  the  first  three  years  of  membership  in  such  an 
organization. If this proposal is adopted, our equity in earnings from ATC would be reduced by approximately $1 million pre-
tax annually.

ATC’s most recent 10-year transmission assessment, which covers the years 2022 through 2031, identifies a need for between 
$5.1 billion and $6.2 billion in transmission system investments. These investments by ATC, if undertaken, are expected to be 
funded through a combination of internally generated cash, debt and investor contributions. As opportunities arise, we plan to 
make additional investments in ATC through general capital calls based upon our pro rata ownership interest in ATC.

Properties

Our Regulated Operations businesses own office and service buildings, an energy control center, repair shops, electric plants, 
transmission facilities and storerooms in various localities in Minnesota, Wisconsin and North Dakota. All of the electric plants 
are subject to mortgages, which collateralize the outstanding first mortgage bonds of Minnesota Power and SWL&P. Most of 
the generating plants and substations are located on real property owned by Minnesota Power or SWL&P, subject to the lien of 
a  mortgage,  whereas  most  of  the  transmission  and  distribution  lines  are  located  on  real  property  owned  by  others  with 
appropriate  easement  rights  or  necessary  permits  from  governmental  authorities.  WPPI  Energy  owns  20  percent  of  Boswell 
Unit  4.  WPPI  Energy  has  the  right  to  use  our  transmission  line  facilities  to  transport  its  share  of  Boswell  generation.  (See 
Note 3. Jointly-Owned Facilities and Assets.)

Regulatory Matters

We are subject to the jurisdiction of various regulatory authorities and other organizations. Regulatory matters and proceedings 
are detailed in Note 4. Regulatory Matters, with a summary included in the following paragraphs.

Electric  Rates.  All  rates  and  contract  terms  in  our  Regulated  Operations  are  subject  to  approval  by  applicable  regulatory 
authorities. Minnesota Power and SWL&P design their retail electric service rates based on cost of service studies under which 
allocations are made to the various classes of customers as approved by the MPUC or the PSCW. Nearly all retail sales include 
billing  adjustment  clauses,  which  may  adjust  electric  service  rates  for  changes  in  the  cost  of  fuel  and  purchased  energy, 
recovery  of  current  and  deferred  conservation  improvement  program  expenditures  and  recovery  of  certain  transmission, 
renewable and environmental investments.

Minnesota Public Utilities Commission. The MPUC has regulatory authority over Minnesota Power’s retail service area in 
Minnesota,  retail  rates,  retail  services,  capital  structure,  issuance  of  securities  and  other  matters.  Minnesota  Power’s  current 
retail rates through 2021 were based on a 2018 MPUC retail rate order that allows for a 9.25 percent return on common equity 
and a 53.81 percent equity ratio. The resolution of Minnesota Power’s 2020 general rate case did not change the allowed return 
on  equity  or  equity  ratio.  (See  2020  Minnesota  General  Rate  Case.)  As  authorized  by  the  MPUC,  Minnesota  Power  also 
recognizes revenue under cost recovery riders for transmission and renewable investments.

Regulatory Matters (Continued)

2020 Minnesota General Rate Case. In November 2019, Minnesota Power filed a retail rate increase request with the MPUC 
seeking an average increase of approximately 10.6 percent for retail customers.

In April 2020, Minnesota Power filed a request with the MPUC that proposed a resolution of Minnesota Power’s 2020 general 
rate case. Key components of our proposal included removing the power marketing margin credit in base rates and reflecting 
actual  power  marketing  margins  in  the  fuel  adjustment  clause  effective  May  1,  2020;  refunding  to  customers  interim  rates 
collected through April 2020; increasing customer rates 4.1 percent compared to the 5.8 percent increase reflected in interim 
rates;  and  a  provision  that  Minnesota  Power  would  not  file  another  rate  case  until  at  least  November  1,  2021,  unless  certain 
events occur. In a June 2020 order, the MPUC approved Minnesota Power’s petition and proposal to resolve and withdraw the 
general rate case. Effective May 1, 2020, customer rates were set at an increase of 4.1 percent with the removal of the power 
marketing  margin  credit  from  base  rates.  Actual  power  marketing  margins  are  now  reflected  in  the  fuel  adjustment  clause. 
Reserves for interim rates of $11.7 million were recorded in the second quarter of 2020 and refunded in the third and fourth 
quarters of 2020.

2022  Minnesota  General  Rate  Case.  On  November  1,  2021,  Minnesota  Power  filed  a  retail  rate  increase  request  with  the 
MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 
10.25  percent  and  a  53.81  percent  equity  ratio.  On  an  annualized  basis,  the  requested  final  rate  increase  would  generate 
approximately  $108  million  in  additional  revenue.  In  orders  dated  December  30,  2021,  the  MPUC  accepted  the  filing  as 
complete and authorized an annual interim rate increase beginning January 1, 2022, with approximately $80 million expected to 
be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination 
on recovery at the end of the rate case.

At a hearing on January 23, 2023, the MPUC made determinations regarding Minnesota Power’s general rate case including 
allowing a return on common equity of 9.65 percent and a 52.50 percent equity ratio. Upon commencement of final rates, we 
expect additional revenue from base rates of approximately $60 million and an additional $10 million in revenue recognized 
under cost recovery riders on an annualized basis, subject to final written order and reconsideration. Final rates are expected to 
commence in the third quarter of 2023; interim rates will be collected through this period with reserves recorded as necessary. 
As a result of the MPUC’s determinations made on January 23, 2023, Minnesota Power has recorded a reserve for an interim 
rate refund of approximately $18 million pre-tax as of December 31, 2022, which is subject to MPUC approval of Minnesota 
Power’s refund calculation. In addition, Minnesota Power recorded a charge of approximately $8 million pre-tax to write-off 
the deferred portion of residential customer interim rates. Minnesota Power also recorded additional revenue of approximately 
$9 million pre-tax for an increase in expected recoveries under its cost recovery riders.

Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that 
surrounds several reservoirs on its hydroelectric system and is no longer required to maintain its operations. The land has an 
estimated value of approximately $100 million, and Minnesota Power proposed to credit ratepayers the net proceeds from the 
sales  in  a  future  rate  case  or  through  its  renewable  resources  rider  to  mitigate  future  rate  increases.  In  an  order  dated 
November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers subject to 
certain conditions and required compliance filings.

2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP, which was approved by the MPUC 
in  an  order  dated  January  9,  2023.  The  approved  IRP,  which  reflects  a  joint  agreement  reached  with  various  stakeholders, 
outlines Minnesota Power’s clean-energy transition plans through 2035. These plans include expanding its renewable energy 
supply,  achieving  coal-free  operations  at  its  facilities  by  2035,  and  investing  in  a  resilient  and  flexible  transmission  and 
distribution  grid.  As  part  of  these  plans,  Minnesota  Power  anticipates  adding  up  to  700  MW  of  new  wind  and  solar  energy 
resources,  and  ceasing  coal  operations  at  Boswell  Units  3  and  4  by  2030  and  2035,  respectively.  Minnesota  Power’s  plans 
recognize  that  advances  in  technology  will  play  a  significant  role  in  completing  its  transition  to  carbon-free  energy  supply, 
reliably and affordably. Minnesota Power is expected to file its next IRP by March 1, 2025.

Minnesota Power has a vision to deliver 100 percent carbon-free energy to customers by 2050, continuing its commitment to 
climate,  customers  and  communities  through  its  EnergyForward  strategy.  This  vision  builds  on  Minnesota  Power’s  
achievement, in 2020, of now providing 50 percent renewable energy to its customers.

REGULATED OPERATIONS (Continued)
Regulatory Matters (Continued)

Public  Service  Commission  of  Wisconsin.  The  PSCW  has  regulatory  authority  over  SWL&P’s  retail  sales  of  electricity, 
natural gas and water, issuances of securities and other matters. SWL&P’s retail rates through 2022 were based on a December 
2018 order by the PSCW that allowed for a return on equity of 10.4 percent and a 55.0 percent equity ratio.

In 2022, SWL&P filed a rate increase request with the PSCW seeking an average increase of 3.6 percent for retail customers. 
The filing sought an overall return on equity of 10.4 percent and a 55 percent equity ratio. On an annualized basis, the requested 
final rate increase would have generated an estimated $4.3 million in additional revenue. In an order dated December 20, 2022, 
the PSCW approved an annual increase of $3.3 million reflecting a return on equity of 10.0 percent and 55 percent equity ratio. 
Final rates went into effect January 1, 2023.

North  Dakota  Public  Service  Commission.  The  NDPSC  has  jurisdiction  over  site  and  route  permitting  of  generation  and 
transmission facilities in North Dakota.

Federal  Energy  Regulatory  Commission.  The  FERC  has  jurisdiction  over  the  licensing  of  hydroelectric  projects,  the 
establishment of rates and charges for transmission of electricity in interstate commerce, electricity sold at wholesale (including 
the  rates  for  Minnesota  Power’s  municipal  and  wholesale  customers),  natural  gas  transportation,  certain  accounting  and 
record-keeping practices, certain activities of our regulated utilities and the operations of ATC. FERC jurisdiction also includes 
enforcement of NERC mandatory electric reliability standards. Violations of FERC rules are subject to enforcement action by 
the FERC including financial penalties up to $1 million per day per violation.

Regional Organizations

Midcontinent Independent System Operator, Inc. Minnesota Power, SWL&P and ATC are members of MISO, a regional 
transmission organization. While Minnesota Power and SWL&P retain ownership of their respective transmission assets, their 
transmission  networks  are  under  the  regional  operational  control  of  MISO.  Minnesota  Power  and  SWL&P  take  and  provide 
transmission  service  under  the  MISO  open  access  transmission  tariff.  In  cooperation  with  stakeholders,  MISO  manages  the 
delivery of electric power across 15 states and the Canadian province of Manitoba.

North  American  Electric  Reliability  Corporation.  The  NERC  has  been  certified  by  the  FERC  as  the  national  electric 
reliability organization. The NERC ensures the reliability of the North American bulk power system. The NERC oversees six 
regional entities that establish requirements, approved by the FERC, for reliable operation and maintenance of power generation 
facilities  and  transmission  systems.  Minnesota  Power  is  subject  to  these  reliability  requirements  and  can  incur  significant 
penalties for non-compliance.

Midwest  Reliability  Organization  (MRO).  Minnesota  Power  and  ATC  are  members  of  the  MRO,  one  of  the  six  regional 
entities  overseen  by  the  NERC.  The  MRO's  primary  responsibilities  are  to:  ensure  compliance  with  mandatory  reliability 
standards by entities which own, operate or use the interconnected, international bulk power system; conduct assessments of the 
grid's ability to meet electricity demand in the region; and analyze regional system events. The MRO region spans the Canadian 
provinces of Saskatchewan and Manitoba, and all or parts of 16 states. 

Minnesota Legislation

Renewable and Carbon-Free Energy Requirements. On February 7, 2023, the Minnesota Governor signed into law legislation 
that  updates  the  state’s  renewable  energy  standard  and  requires  Minnesota  electric  utilities  to  source  retail  sales  with 
100 percent carbon-free energy by 2040. The law increases the renewable energy standard from 25 percent renewable by 2025 
to 55 percent renewable by 2035, and requires investor-owned Minnesota utilities to provide 80 percent carbon-free energy by 
2030, 90 percent carbon-free energy by 2035 and 100 percent carbon-free energy by 2040. The law utilizes renewable energy 
credits as the means to demonstrate compliance with both the carbon-free and renewable energy standards, includes an off ramp 
provision that enables the MPUC to protect reliability and customer costs through modification or delay of either the renewable 
energy standard, the carbon-free standard, or both, and streamlines development and construction of wind energy projects and 
transmission in Minnesota. The Company is evaluating the law to identify challenges and opportunities it could present. 

As of December 31, 2022, approximately 50 percent of Minnesota Power’s power supply for its retail and municipal customers 
in  Minnesota  was  provided  by  renewable  energy  sources.  Minnesota  Power’s  plans  include  expanding  its  renewable  energy 
supply to 70 percent renewable energy by 2030. (See Item 7. Management’s Discussion and Analysis of Financial Condition 
and Results of Operations – Outlook – EnergyForward.)

REGULATED OPERATIONS (Continued)
Minnesota Legislation (Continued)

Minnesota Solar Energy Standard. Minnesota law requires at least 1.5 percent of total retail electric sales, excluding sales to 
certain customers, to be generated by solar energy. At least 10 percent of the 1.5 percent mandate must be met by solar energy 
generated  by  or  procured  from  solar  photovoltaic  devices  with  a  nameplate  capacity  of  40  kW  or  less  and  community  solar 
garden subscriptions. Minnesota Power has met both parts of the solar mandate to date.

Competition

Retail electric energy sales in Minnesota and Wisconsin are made to customers in assigned service territories. As a result, most 
retail electric customers in Minnesota do not have the ability to choose their electric supplier. Large energy users of 2 MW and 
above  that  are  located  outside  of  a  municipality  are  allowed  to  choose  a  supplier  upon  MPUC  approval.  Minnesota  Power 
served seven Large Power Customers under contracts of at least 10 MW in 2022, none of which have engaged in a competitive 
rate process. (See Electric Sales / Customers.) No other large commercial or small industrial customers in Minnesota Power’s 
service territory have sought a provider outside Minnesota Power’s service territory. Retail electric and natural gas customers in 
Wisconsin do not have the ability to choose their energy supplier. In both states, however, electricity may compete with other 
forms  of  energy.  Customers  may  also  choose  to  generate  their  own  electricity,  or  substitute  other  forms  of  energy  for  their 
manufacturing processes.

In 2022, 4 percent of total regulated utility kWh sales were to municipal customers in Minnesota. These customers have the 
right  to  seek  an  energy  supply  from  any  wholesale  electric  service  provider  upon  contract  expiration.  Minnesota  Power’s 
wholesale  electric  contract  with  the  Nashwauk  Public  Utilities  Commission  was  extended  in  2020  and  is  effective  through 
December  31,  2037.  Minnesota  Power’s  wholesale  electric  contracts  with  13  other  non-affiliated  municipal  customers  are 
effective through 2029. (See Electric Sales / Customers.)

The FERC has continued with its efforts to promote a competitive wholesale market through open-access electric transmission 
and other means. As a result, our electric sales to Other Power Suppliers and our purchases to supply our retail and wholesale 
load are made in a competitive market.

Franchises

Minnesota Power holds franchises to construct and maintain an electric distribution and transmission system in 95 cities. The 
remaining  cities,  villages  and  towns  served  by  Minnesota  Power  do  not  require  a  franchise  to  operate.  SWL&P  serves 
customers under electric, natural gas or water franchises in 1 city and 14 villages and towns.

ALLETE CLEAN ENERGY

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean 
Energy currently owns and operates, in seven states, more than 1,200 MW of nameplate capacity wind energy generation  with 
a majority contracted under PSAs of various durations. In addition, ALLETE Clean Energy engages in the development of wind 
energy facilities to operate under long-term PSAs or for sale to others upon completion. ALLETE Clean Energy currently has 
approximately 100 MW of wind energy facilities under contract to be sold to others. (See Item 7. Management’s Discussion 
and Analysis of Financial Condition and Results of Operations – Outlook – ALLETE Clean Energy.)

ALLETE  Clean  Energy  believes  the  market  for  renewable  energy  in  North  America  is  robust,  driven  by  several  factors 
including  environmental  regulation,  tax  incentives  such  as  the  extension  of  production  tax  credit  and  investment  tax  credits, 
societal  expectations  and  continual  technology  advances.  State  renewable  portfolio  standards,  state  or  federal  regulations  to 
limit  GHG  emissions  and  the  extension  of  production  tax  credit  and  investment  tax  credits  are  examples  of  environmental 
regulation or public policy that we believe will drive renewable energy development.

ALLETE CLEAN ENERGY (Continued)

ALLETE  Clean  Energy’s  strategy  includes  the  safe,  reliable,  optimal  and  profitable  operation  of  its  existing  facilities.  This 
includes  a  strong  safety  culture,  the  continuous  pursuit  of  operational  efficiencies  at  existing  facilities  and  cost  controls. 
ALLETE Clean Energy generally acquires facilities in liquid power markets and its strategy includes the exploration of PSA 
extensions  upon  expiration  of  existing  contracts,  production  tax  credit  requalification  of  existing  facilities  or  the  sale  of 
facilities.

ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and 
geographic diversity. The current operating portfolio is subject to typical variations in seasonal wind with higher wind resources 
typically available in the winter months. The majority of its planned maintenance leverages this seasonality and is performed 
during lower wind periods. ALLETE Clean Energy’s current operating portfolio is as follows:

Investment in Nobles 2

Our  subsidiary,  ALLETE  South  Wind,  owns  a  49  percent  equity  interest  in  Nobles  2,  the  entity  that  owns  and  operates  a 
250  MW  wind  energy  facility  in  southwestern  Minnesota  pursuant  to  a  20-year  PPA  with  Minnesota  Power.  As  of 
December 31, 2022, our equity investment in Nobles 2 was $157.3 million ($163.5 million at December 31, 2021). (See Note 6. 
Equity Investments.)

South Shore Energy

South  Shore  Energy,  ALLETE’s  non-rate  regulated,  Wisconsin  subsidiary,  is  developing  NTEC,  an  approximately  600  MW 
proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned 
by  Dairyland  Power  Cooperative,  Basin  and  South  Shore  Energy.  Minnesota  Power  is  expected  to  purchase  approximately 
20 percent of the facility's output starting in 2027 pursuant to a capacity dedication agreement. Construction of NTEC is subject 
to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately 
$700  million,  of  which  South  Shore  Energy’s  portion  is  expected  to  be  approximately  $150  million.  South  Shore  Energy’s 
portion of NTEC project costs incurred through December 31, 2022, is approximately $7 million.

BNI Energy

BNI Energy is a supplier of lignite coal in North Dakota, producing approximately 4 million tons annually and has an estimated 
650  million  tons  of  lignite  coal  reserves.  Two  electric  generating  cooperatives,  Minnkota  Power  and  Square  Butte,  consume 
virtually  all  of  BNI  Energy’s  production  of  lignite  under  cost-plus  fixed  fee  coal  supply  agreements  extending  through 
December 31, 2037. (See Item 1. Business – Regulated Operations – Power Supply – Long-Term Purchased Power and Note 9. 
Commitments, Guarantees and Contingencies.) The mining process disturbs and reclaims between 200 and 250 acres per year. 
Laws  require  that  the  reclaimed  land  be  at  least  as  productive  as  it  was  prior  to  mining.  As  of  December  31,  2022,  BNI 
Energy’s  total  reclamation  liability  is  estimated  at  $82.1  million,  which  is  included  in  Other  Non-Current  Liabilities  on  the 
Consolidated Balance Sheet at its present value. These costs are included in the cost-plus fixed fee contract, for which an asset 
reclamation  cost  receivable  was  included  in  Other  Non-Current  Assets  on  the  Consolidated  Balance  Sheet.  The  asset 
reclamation  obligation  is  guaranteed  by  surety  bonds  and  a  letter  of  credit.  (See  Note  9.  Commitments,  Guarantees  and 
Contingencies.)

ALLETE Properties

ALLETE Properties represents our legacy Florida real estate investment. ALLETE Properties’ major project in Florida is Town 
Center at Palm Coast, which consists of approximately 300 acres of land as well as various residential units and non-residential 
square footage. In addition to the Town Center at Palm Coast project, ALLETE Properties has approximately 500 acres of other 
land available for sale. (See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – 
Outlook – Corporate and Other – ALLETE Properties.)

Seller  Financing.  ALLETE  Properties  occasionally  provides  seller  financing  to  qualified  buyers.  As  of  December  31,  2022, 
outstanding  finance  receivables  were  $10.5  million,  net  of  reserves,  with  maturities  through  2027.  These  finance  receivables 
accrue interest at market-based rates and are collateralized by the financed properties.

Regulation. A substantial portion of our development properties in Florida are subject to federal, state and local regulations, 
and restrictions that may impose significant costs or limitations on our ability to develop the properties. Much of our property is 
vacant land and some is located in areas where development may affect the natural habitats of various protected wildlife species 
or in sensitive environmental areas such as wetlands.

Non-Rate Base Generation and Miscellaneous

ENVIRONMENTAL MATTERS

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of 
regulatory  changes  to  the  Clean  Air  Act,  the  Clean  Water  Act  and  various  waste  management  requirements  have  been 
promulgated  by  both  the  EPA  and  state  authorities  over  the  past  several  years.  Minnesota  Power’s  facilities  are  subject  to 
additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to 
reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy 
during rulemaking implementation.

We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all 
necessary  permits  have  been  obtained.  We  anticipate  that  with  many  state  and  federal  environmental  regulations  and 
requirements  finalized,  or  to  be  finalized  in  the  near  future,  potential  expenditures  for  future  environmental  matters  may  be 
material  and  require  significant  capital  investments.  Minnesota  Power  has  evaluated  various  environmental  compliance 
scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers.

We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that 
a  liability  has  been  incurred  and  the  amount  of  the  liability  can  be  reasonably  estimated  based  on  current  law  and  existing 
technologies.  Accruals  are  adjusted  as  assessment  and  remediation  efforts  progress,  or  as  additional  technical  or  legal 
information  becomes  available.  Accruals  for  environmental  liabilities  are  included  in  the  Consolidated  Balance  Sheet  at 
undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental 
contamination  treatment  and  cleanup  are  expensed  unless  recoverable  in  rates  from  customers.  (See  Note  9.  Commitments, 
Guarantees and Contingencies.)

HUMAN CAPITAL MANAGEMENT

The  Company’s  key  human  capital  management  objectives  are  to  attract,  recognize  and  retain  high  quality  talent,  align  with 
strategic  business  objectives  and  support  the  Company’s  values.  To  support  these  objectives,  the  Company’s  programs  are 
designed  to  develop  talent;  reward  and  support  employees  through  competitive  compensation  programs  and  benefit  plans; 
enhance the Company’s culture through efforts aimed at making the workplace more engaging, safe and inclusive; and acquire 
talent and leverage internal opportunities to create a high-performing, diverse workforce. Our management, the ALLETE Board 
of Directors Executive Compensation and Human Capital Committee, and our Board of Directors as a whole play key roles in 
reviewing and overseeing our human capital practices.

As of December 31, 2022, ALLETE had 1,494 employees, of which 1,467 were full-time. We also respect employees’ freedom 
of  association  and  their  right  to  collectively  organize.  As  of  December  31,  2022,  Minnesota  Power  and  SWL&P  have  an 
aggregate of 484 employees covered under collective bargaining agreements, of which most are members of the International 
Brotherhood of Electrical Workers (IBEW) Local 31. The current labor agreements with IBEW Local 31 expire on April 30, 
2023  for  Minnesota  Power  and  January  31,  2024  for  SWL&P.  BNI  Energy  has  127  employees  that  are  members  of  IBEW 
Local 1593. The current labor agreement with IBEW Local 1593 expires on March 31, 2023.

ALLETE’s Human Rights Statement confirms our commitment to the advancement and protection of human rights, consistent 
with U.S. human rights laws and the general principles in the International Labour Organization Conventions.

Integrity. Integrity is a foundational, shared value at ALLETE, is important to ALLETE’s business and operations, and enables 
our success. The Company has a written Code of Business Conduct that applies to all of our employees, directors of ALLETE, 
contractors, vendors, and others who do business with or on behalf of ALLETE.

Health and Safety. The success of our business is fundamentally connected to the well-being of our people. Our journey to 
Zero Injury starts with a culture that is open and transparent. We encourage all employees to report injuries, near misses, and 
good catches, so that we can learn and share with others throughout the Company in an effort to improve safety performance. 
Leaders  have  regular  safety  conversations  with  employees,  where  hazard  identification  and  controls  are  discussed  to  ensure 
work is being performed safely. Conversations are documented and the data is collected and analyzed for trends. To monitor 
progress, the Company uses leading and lagging indicators to analyze injury trends, safety participation and other data to make 
better decision on safety practices.

HUMAN CAPITAL MANAGEMENT (Continued)

Talent Attraction, Retention and Development. For more than a century, ALLETE has been successful because of our ability 
to attract and retain high-quality people who demonstrate our shared values. We engage in workforce planning, and succession 
planning, while building a robust talent pipeline and monitoring turnover.

We recognize and support the growth and development of our employees and offer opportunities to participate in internal and 
external  learning  programs.  Our  internal  talent  development  programs  provide  employees  with  the  resources  they  need  to 
develop  proficiency  in  their  role,  help  achieve  their  career  goals  and  build  leadership  skills.  We  are  focusing  initiatives  on 
programs to expand the diversity of new hires and updating on-the-job trainings—including apprenticeships and scholarships 
aimed  at  bridging  opportunity  gaps—as  we  recognize  the  importance  of  a  strong  talent  pipeline.  In  addition  to  role  specific 
training, targeted training also includes respect in the workplace, cyber awareness, safety, integrity and leadership development.

Compensation  and  Benefits.  Our  competitive  compensation  package  gives  employees  flexibility,  choices  and  opportunities. 
Competitive compensation is important for the Company to attract and retain a qualified workforce to successfully manage our 
business and achieve our business objectives. We also strive to ensure pay equity amongst diverse employees performing equal 
or substantially similar work. Periodically, we review the median pay of our male and female employees as well as employees 
from diverse backgrounds. 

Diversity,  Equity  and  Inclusion.  Increasing  diversity  enriches  our  workforce  culture  at  ALLETE.  Our  employees  are 
operating in an increasingly diverse society. In order to be accountable to our employees and stakeholders, we strive to have a 
workforce that reflects the diversity of the communities we serve, promotes inclusivity and is equitable.

At ALLETE, we want to ensure that we have a workplace culture where we treat each other with fairness, dignity and respect. 
The  Company  has  a  respect  in  the  workplace  initiative,  which  includes  education  as  well  as  ongoing  discussions  focused  on 
building respectful relationships and managing bias. We continue our efforts in crafting a framework to strengthen ALLETE’s 
diversity, equity and inclusion efforts in the areas of: workforce, supply chain, communications, customers, and ALLETE as a 
community citizen. ALLETE continues to take tangible steps toward advancing diversity, equity and inclusion by continuing to 
raise  awareness,  furthering 
increasing  supplier  diversity,  focus  on 
underrepresented groups through grants/scholarships and other Company and employee giving.

Yellow  Ribbon  Program.  ALLETE  and  its  subsidiaries  are  dedicated  to  supporting  veterans,  military  members  and  their 
families.  An  employee  effort  grew  out  of  that  spirit  of  commitment  to  veterans  and  led  the  state  of  Minnesota  to  designate 
ALLETE/Minnesota  Power  and  ALLETE  Clean  Energy  as  Yellow  Ribbon  Companies.  The  mission  of  ALLETE’s  Yellow 
Ribbon  Program  is  to  contribute  to  the  Company’s  unique  culture  by  proactively  recruiting  and  retaining  the  best  and 
supporting an environment in which military-connected employees can thrive.

Item 1A. Risk Factors

The  risks  and  uncertainties  discussed  below  could  materially  affect  our  business  operations,  financial  position,  results  of 
operations and cash flows, and should be carefully considered by stakeholders. The risks and uncertainties in this section are 
not the only ones we face; additional risks and uncertainties that we are not presently aware of, or that we currently consider 
immaterial, may also affect our business operations, financial position, results of operations and cash flows. Accordingly, the 
risks described below should be carefully considered together with other information set forth in this report and in future reports 
that we file with the SEC.

Regulated Operations Risks

Our  results  of  operations  could  be  negatively  impacted  if  our  taconite,  paper  and  pipeline  customers  experience  an 
economic  downturn,  incur  work  stoppages,  fail  to  compete  effectively,  experience  decreased  demand,  fail  to 
economically obtain raw materials, fail to renew or obtain necessary permits, or experience a decline in prices for their 
product.

Minnesota Power’s Large Power Customers (see Item 1. Business – Regulated Operations – Electric Sales / Customers) and 
Silver Bay Power accounted for 29 percent of our 2022 consolidated operating revenue (32 percent in 2021 and 29 percent in 
2020)  and  36  percent  of  Regulated  Operations  operating  revenue  (37  percent  in  2021  and  34  percent  in  2020).  Minnesota 
Power’s taconite customers, which are currently owned by only two entities at the end of 2022, accounted for approximately 
26  percent  of  consolidated  operating  revenue  and  32  percent  of  Regulated  Operations  operating  revenue  in  2022.  These 
customers are involved in cyclical industries that by their nature are adversely impacted by economic downturns and are subject 
to strong competition in the marketplace. The North American paper and pulp industry also faces declining demand due to the 
impact  of  electronic  substitution  for  print  and  changing  customer  needs.  As  a  result,  certain  paper  and  pulp  customers  have 
reduced their existing operations or idled facilities in recent years and have pursued or are pursuing product changes in response 
to declining demand. Additionally, the taconite industry could be impacted by changing technology in the steel industry such as 
the  adoption  of  electric  arc  furnaces  for  steelmaking,  which  could  result  in  declining  demand  for  taconite  and  the  electricity 
used during its production.

Minnesota Power also serves two pipeline customers that accounted for 2 percent of our 2022 consolidated operating revenue 
(2 percent in 2021 and in 2020) and 2 percent of Regulated Operations revenue in 2022 (2 percent in 2021 and 3 percent in 
2020). These customers are involved in an industry that is seeing increased environmental pressure for construction of new or 
expanded pipeline infrastructure for the transportation of fossil fuels. Changes in regulatory rulings or permit proceedings could 
result in changes to operations of the pipeline network in our service territory.

Accordingly, if our industrial customers experience an economic downturn, incur a work stoppage (including strikes, lock-outs 
or  other  events),  fail  to  compete  effectively,  experience  decreased  demand,  fail  to  economically  obtain  raw  materials,  fail  to 
renew or obtain necessary permits, or experience a decline in demand or prices for their product, there could be adverse effects 
on  their  operations  and,  consequently,  this  could  have  a  negative  impact  on  our  results  of  operations  as  we  are  unable  to 
remarket at similar prices the energy that would otherwise have been sold to such customers.

We  may  not  be  able  to  successfully  implement  our  strategic  objectives  of  growing  load  at  our  utilities  if  current  or 
potential  industrial  or  municipal  customers  are  unable  to  successfully  implement  expansion  plans,  including  the 
inability to obtain necessary governmental permits and approvals.

As part of our long-term strategy, we pursue new wholesale and retail loads in and around our service territories. Currently, 
there are several companies in northeastern Minnesota that are in the process of developing natural resource-based projects that 
represent long-term growth potential and load diversity for our Regulated Operations businesses. These projects may include 
construction of new facilities and restarts of old facilities, both of which require permitting and approvals to be obtained before 
the  projects  can  be  successfully  implemented.  If  a  project  does  not  obtain  any  necessary  governmental  (including 
environmental)  permits  and  approvals  or  if  these  customers  are  unable  to  successfully  implement  expansion  plans,  our  long-
term strategy and thus our results of operations could be adversely impacted.

Item 1A. Risk Factors (Continued)
Regulated Operations Risks (Continued)

Our businesses, investments and customers are subject to an extensive legal and regulatory framework under federal 
and state laws as well as regulations imposed by other organizations that may have a negative impact on our business 
and results of operations.

Our businesses, investments and customers are subject to an extensive legal and regulatory framework imposed under federal 
and state law including regulations administered by the FERC, MPUC, MPCA, PSCW, NDPSC and EPA as well as regulations 
administered by other organizations including the NERC. These laws and regulations relate to allowed rates of return, capital 
structure,  financings,  rate  and  cost  structure,  acquisition  and  disposal  of  assets  and  facilities,  construction  and  operation  of 
generation, transmission and distribution facilities (including the ongoing maintenance and reliable operation of such facilities), 
recovery  of  purchased  power  costs  and  capital  investments,  approval  of  integrated  resource  plans  and  present  or  prospective 
wholesale and retail competition, renewable portfolio standards that require utilities to obtain specified percentages of electric 
supply  from  eligible  renewable  generation  sources,  among  other  things.  Energy  policy  initiatives  at  the  state  or  federal  level 
could  increase  or  accelerate  renewable  and  carbon-free  energy  standards  or  incentives  for  distributed  generation,  municipal 
utility  ownership,  or  local  initiatives  could  introduce  generation  or  distribution  requirements  that  could  change  the  current 
integrated utility model. (See Item 1. Business – Regulated Operations – Minnesota Legislation.) Our transmission systems and 
electric  generation  facilities  are  subject  to  the  NERC  mandatory  reliability  standards,  including  cybersecurity  standards. 
Compliance with these standards may lead to increased operating costs and capital expenditures which are subject to regulatory 
approval for recovery. If it was determined that we were not in compliance with these mandatory reliability standards or other 
statutes, rules and orders, we could incur substantial monetary penalties and other sanctions, which could adversely affect our 
results of operations.

These  laws  and  regulations  significantly  influence  our  operations  and  may  affect  our  ability  to  recover  costs  from  our 
customers.  We  are  required  to  have  numerous  permits,  licenses,  approvals  and  certificates  from  the  agencies  and  other 
organizations that regulate our business. We believe we have obtained the necessary permits, licenses, approvals and certificates 
for our existing operations and that our business is conducted in accordance with applicable laws; however, we are unable to 
predict the impact on our operating results from the future regulatory activities of any of these agencies and other organizations. 
Changes in regulations, timing of approvals, the adoption of new regulations or the expansion of jurisdiction by these agencies 
and other organizations could have an adverse impact on our business and results of operations.

Our ability to obtain rate adjustments to maintain reasonable rates of return depends upon regulatory action under applicable 
statutes and regulations, and we cannot provide assurance that rate adjustments will be obtained or reasonable authorized rates 
of return on capital will be earned. Minnesota Power and SWL&P, from time to time, file general rate cases with, or otherwise 
seek cost recovery authorization from, federal and state regulatory authorities. If Minnesota Power and SWL&P do not receive 
an  adequate  amount  of  rate  relief  in  general  rate  cases,  including  if  rates  are  reduced,  if  increased  rates  are  not  approved  or 
recovered on a timely basis, if fuel adjustment clause recoveries or cost recovery for other items are not granted at the requested 
level,  or  costs  are  otherwise  unable  to  be  recovered  through  rates,  we  may  experience  an  adverse  impact  on  our  financial 
position, results of operations and cash flows. We are unable to predict the impact on our business and results of operations 
from future legislation or regulatory activities of any of these agencies or organizations.

Our  regulated  operations  present  certain  environmental  risks  that  could  adversely  affect  our  financial  position  and 
results  of  operations,  including  effects  of  environmental  laws  and  regulations,  physical  risks  associated  with  climate 
change and initiatives designed to reduce the impact of GHG emissions.

We  are  subject  to  extensive  environmental  laws  and  regulations  affecting  many  aspects  of  our  past,  present  and  future 
operations, including air quality, water quality and usage, waste management, reclamation, hazardous wastes, avian mortality 
and  natural  resources.  These  laws  and  regulations,  or  new  laws  and  regulations  that  may  be  passed,  can  result  in  increased 
capital expenditures and increased operating and other costs as a result of compliance, remediation, containment and monitoring 
obligations, particularly with regard to laws relating to emissions, coal ash and water discharge at generating facilities.

These laws and regulations could restrict the output of some existing facilities, limit the use of some fuels in the production of 
electricity,  require  the  installation  of  additional  pollution  control  equipment,  require  participation  in  environmental  emission 
allowance  trading,  and  lead  to  other  environmental  considerations  and  costs,  which  could  have  an  adverse  impact  on  our 
business, operations and results of operations.

ALLETE, Inc. 2022 Form 10-K
25

Item 1A. Risk Factors (Continued)
Regulated Operations Risks (Continued)

These laws and regulations generally require us to obtain and comply with a wide variety of environmental licenses, permits, 
inspections and other approvals. Violations of these laws and regulations could expose us to regulatory and legal proceedings, 
disputes with, and legal challenges by, governmental authorities and private parties, as well as potential significant civil fines 
criminal penalties and other sanctions.

Existing environmental regulations may be revised and new environmental regulations may be adopted or become applicable to 
us. Revised or additional regulations which result in increased compliance costs or additional operating restrictions, particularly 
if those costs are not fully recoverable from customers, could have an adverse effect on our results of operations.

There is significant uncertainty regarding if and when new laws, regulations or administrative policies will be adopted to reduce 
or  limit  GHG  and  the  impact  any  such  laws  or  regulations  would  have  on  us.  In  2022,  our  operating  coal-fired  generating 
facilities  consisted  of  the  352  MW  Boswell  Unit  3  and  the  468  MW  Boswell  Unit  4.  (See  Outlook  –  EnergyForward.)  Any 
future limits on GHG emissions at the federal or state level, or action taken by regulators, before these facilities are retired or 
become  coal-free  may  require  us  to  incur  significant  capital  expenditures  and  increases  in  operating  costs,  or  could  result  in 
early  closure  of  coal-fired  generating  facilities,  stranded  assets,  an  impairment  of  assets,  denial  of  full  recovery  of 
decommissioning  costs  in  excess  of  amounts  previously  collected,  or  otherwise  adversely  affect  our  results  of  operations, 
particularly if resulting expenditures and costs are not fully recoverable from customers. 

Our  regulated  operations  may  be  adversely  impacted  by  the  physical  and  financial  risks  associated  with  climate  change.  See 
Entity-wide Risks for additional discussion of risks related to GHG and climate change.

We cannot predict the amount or timing of all future expenditures related to environmental matters because of uncertainty as to 
applicable regulations or requirements. There is also uncertainty in quantifying liabilities under environmental laws that impose 
joint  and  several  liability  on  all  potentially  responsible  parties.  Violations  of  certain  environmental  statutes,  rules  and 
regulations  could  expose  ALLETE  to  third  party  disputes  and  potentially  significant  monetary  penalties,  as  well  as  other 
sanctions for non-compliance. 

The operation and maintenance of our regulated electric generation, transmission and distribution facilities are subject 
to operational risks that could adversely affect our financial position, results of operations and cash flows.

The  operation  of  generating  facilities  involves  many  risks,  including  start-up  operational  risks,  breakdown  or  failure  of 
facilities, the dependence on a specific fuel source, inadequate fuel supply, availability of fuel transportation, and the impact of 
unusual  or  adverse  weather  conditions  or  other  natural  events,  as  well  as  the  risk  of  performance  below  expected  levels  of 
output  or  efficiency.  A  significant  portion  of  our  facilities  contain  older  generating  equipment,  which,  even  if  maintained  in 
accordance  with  good  engineering  practices,  may  require  significant  capital  expenditures  to  continue  operating  at  peak 
efficiency. Generation,  transmission and distribution facilities and equipment are also likely to require periodic upgrades and 
improvements due to changing environmental standards and technological advances. We could be subject to costs associated 
with  any  unexpected  failure  to  produce  or  deliver  power,  including  failure  caused  by  breakdown,  forced  outage  or  limited 
availability  of  fuel  or  fuel  transportation,  as  well  as  the  repair  of  damage  to  facilities  due  to  breakdown,  storms,  natural 
disasters,  wars,  sabotage,  terrorist  acts  and  other  catastrophic  events.  This  could  also  lead  to  requiring  additional  purchased 
power  to  meet  requirements  of  serving  our  retail  load,  which  for  Minnesota  Power  is  subject  to  recovery  under  the  fuel 
adjustment  clause.  Should  these  costs  be  denied  or  are  otherwise  unable  to  be  recovered,  our  financial  position,  results  of 
operations and cash flows could be adversely impacted.

Our ability to successfully and timely complete capital repairs or improvements to existing regulated facilities or other 
capital projects is contingent upon many variables.

We expect to incur significant capital expenditures in making capital repairs or improvements to our existing electric generation 
and  transmission  facilities  and  in  the  development  and  construction  of  new  electric  generation  and  transmission  facilities. 
Should any such efforts be unsuccessful, not completed in a timely manner or if there are increases in the costs for or limited 
availability of key materials, supplies, labor and services, we could be subject to additional costs or impairments, and projects 
may be delayed or canceled which could have an adverse impact on our financial position, results of operation and cash flows.

Item 1A. Risk Factors (Continued)
Regulated Operations Risks (Continued)

Our regulated electric operations may not have access to adequate and reliable transmission and distribution facilities 
necessary to deliver electricity to our customers.

We  depend  on  our  own  transmission  and  distribution  facilities,  as  well  as  facilities  owned  by  other  utilities,  to  deliver  the 
electricity  sold  to  our  customers,  and  to  other  energy  suppliers.  If  transmission  capacity  is  inadequate  or  transmission  and 
distribution facilities we rely on are damaged, our ability to sell and deliver electricity may be limited. We may have to forgo 
sales or may have to buy more expensive wholesale electricity that is available in a capacity-constrained area. The ability to 
restore adequate capacity or repair damaged infrastructure may be impacted by the availability of key materials, supplies, labor 
and  services,  which  if  unavailable  may  prolong  the  impact  of  capacity  constraints  or  damaged  facilities.  In  addition,  any 
infrastructure failure or damage that interrupts or impairs delivery of electricity to our customers could negatively impact the 
satisfaction of our customers, which could have an adverse impact on our business and results of operations.

The price of electricity may be volatile and fuel may be volatile and availability may be limited.

Volatility  in  market  prices  for  electricity  and  volatility  and  limited  availability  of  fuel  could  adversely  impact  our  financial 
position and results of operations and may result from:

•
•
•
•
•
•
•
•
•
•
•
•

severe or unexpected weather conditions and natural disasters;
seasonality;
changes in electricity usage;
transmission or transportation constraints, inoperability or inefficiencies;
availability of competitively priced alternative energy sources;
changes in supply and demand for energy;
changes in power production capacity;
outages at our generating facilities or those of our competitors;
availability of fuel and transportation of fuel;
changes in production and storage levels of natural gas, lignite, coal, crude oil and refined products;
wars, sabotage, terrorist acts or other catastrophic events; and
federal, state, local and foreign energy, environmental, or other regulation and legislation.

Volatility  in  market  prices  for  our  fuel  and  purchase  power  costs  impacts  our  sales  to  retail,  municipal  and  Other  Power 
Suppliers. Fluctuations in our fuel and purchased power costs related to our retail and municipal customers are passed on to 
customers through the fuel adjustment clause; however, our results of operations and cash flows may be adversely impacted if 
increased  fuel  adjustment  clause  rates  are  not  approved  or  recovered  on  a  timely  basis,  if  cost  recovery  is  not  granted  at  the 
requested level, or costs are otherwise unable to be recovered through the fuel adjustment clause. 

Wholesale prices for electricity have also declined in recent years primarily due to the extension of renewable tax credits and 
additional  renewable  generation  commencing  operations.  If  there  are  reductions  in  demand  from  current  customers,  we  lose 
retail customers, or we lose municipal customers that do not renew existing contracts, we will market any available power to 
Other Power Suppliers in an effort to mitigate any earnings impact. Sales to Other Power Suppliers are sold at market-based 
prices into the MISO market on a daily basis or through bilateral agreements of various durations. Due to wholesale prices for 
electricity being below our rates for retail and municipal customers, we do not expect that our power marketing efforts would 
fully offset the reduction in earnings resulting from the lower demand from existing customers or the loss of customers. (See 
Item 1. Business – Regulated Operations – Electric Sales / Customers.)

ALLETE, Inc. 2022 Form 10-K

Item 1A. Risk Factors (Continued)
Regulated Operations Risks (Continued)

Demand for energy may decrease.

Our results of operations are impacted by the demand for energy in our service territories, our municipal customers and other 
power  suppliers.  There  could  be  lower  demand  for  energy  due  to  a  loss  of  customers  as  a  result  of  economic  conditions, 
customers  constructing  or  installing  their  own  generation  facilities,  higher  costs  and  rates  charged  to  customers,  eligible 
municipal and other power suppliers choosing an alternative energy provider, or loss of service territory or franchises. Further, 
energy  conservation  and  technological  advances  that  increased  energy  efficiency  may  temporarily  or  permanently  reduce  the 
demand  for  energy  products.  In  addition,  we  are  impacted  by  state  and  federal  regulations  requiring  mandatory  conservation 
measures, which reduce the demand for energy products. Continuing technology improvements and regulatory developments 
may make customer and third party-owned generation technologies such as rooftop solar systems, WTGs, microturbines and 
battery  storage  systems  more  cost  effective  and  feasible  for  certain  customers.  If  customers  utilize  their  own  generation, 
demand  for  energy  from  us  would  decline.  There  may  not  be  future  economic  growth  opportunities  that  would  enable  us  to 
replace the lost energy demand from these customers. Therefore, a decrease in demand for energy could adversely impact our 
financial position, results of operations and cash flows.

ALLETE Clean Energy / Corporate and Other Risks

The inability to successfully manage and grow our businesses could adversely affect our results of operations.

The Company's strategy includes adding customers, new geographies, and growth through acquisitions or project development 
with long-term PSAs in place for the output or to be sold upon completion. This strategy depends, in part, on the Company’s 
ability  to  successfully  identify  and  evaluate  acquisition  or  development  opportunities  and  consummate  acquisitions  on 
acceptable terms. The Company may compete with other companies for these acquisition and development opportunities, which 
may increase the Company’s cost of making acquisitions and the Company may be unsuccessful in pursuing these acquisition 
opportunities.  Other  companies  may  be  able  to  pay  more  for  acquisitions  and  may  be  able  to  identify,  evaluate,  bid  for  and 
purchase  a  greater  number  of  assets  than  the  Company’s  financial  or  human  resources  permit.  New  laws  and  regulations 
promoting  renewable  energy  generation  may  result  in  increased  competition.  Our  ALLETE  Clean  Energy  business  is 
experiencing return pressures from increased competition, and lower forward price curves, as a growing amount of investment 
capital is being directed into wind energy generation opportunities. In addition, current and potential new project developments 
at  our  businesses  can  be  negatively  affected  by  a  lower  ALLETE  stock  price,  which  may  result  in  such  projects  not  being 
accretive,  or  otherwise  unable  to  satisfy  our  financial  objectives  criteria  to  proceed.  Additionally,  tax  law  changes  may 
adversely impact the economic characteristics of potential acquisitions or investments. If the Company is unable to execute its 
strategy of growth through acquisitions, project development for others, or the addition of new customers and geographies, it 
may impede our long-term objectives and business strategy.

Acquisitions are subject to uncertainties. If we are unable to successfully integrate and manage the acquisition of New Energy, 
or  future  acquisitions  and  strategic  investments,  this  could  have  an  adverse  impact  on  our  results  of  operations.  Our  actual 
results  may  also  differ  from  our  expectations  due  to  factors  such  as  the  ability  to  obtain  timely  regulatory  or  governmental 
approvals, integration and operational issues and the ability to retain management and other key personnel.

Our  results  of  operations  could  be  adversely  affected  by  changes  in  governmental  incentives  or  policies  that  support 
renewable  energy  or  changes  in  taxes,  tariffs,  duties  or  other  assessments  on  renewable  energy  or  the  equipment 
necessary to generate and deliver it.

Any reductions or modifications to, or the elimination of, governmental incentives or policies that support renewable energy, or 
the  imposition  of  additional  or  increased  sourcing  of  components  subject  to  taxes,  tariffs,  duties  or  other  assessments  on 
renewable  energy  or  the  equipment  necessary  to  generate  and  deliver  it,  could  result  in,  among  other  items,  the  lack  of  a 
satisfactory market for the development or financing of new renewable energy projects and reduced project returns on current 
or future projects.

The U.S. government currently imposes antidumping and countervailing duties on certain imported photovoltaic (PV) cells and 
modules  from  China  and  Taiwan.  Such  duties  can  change  over  time  pursuant  to  annual  reviews  conducted  by  the  U.S. 
Department of Commerce (DOC). In March 2022, the U.S. DOC launched an investigation into alleged circumvention of these 
duties by imports of certain PV cells and modules assembled and completed in Cambodia, Malaysia, Thailand, and Vietnam. In 
June 2022, the U.S. President declared an emergency with respect to threats to electricity generation capacity and authorized the 
U.S. Secretary of Commerce to consider permitting the importation of certain PV products from those four countries free of 
antidumping and countervailing duties for 24 months, or until the emergency has terminated. The U.S. DOC has issued final 
regulations designed to implement that moratorium in the event that it finds circumvention in its ongoing inquiries. We cannot 
predict what further actions the U.S. DOC will take with respect to these circumvention inquiries. Our operating results could 
be adversely impacted if the U.S. DOC makes circumvention determinations that result in duties assessed on future purchases 
made by our businesses after the moratorium ends.

The generation of electricity from wind and solar energy facilities depends heavily on suitable meteorological conditions.

Although our electric generation facilities are located in diverse geographic regions to reduce the potential impact that may be 
caused by unfavorable weather in a particular region, suitable meteorological conditions are variable and difficult to predict. If 
wind or solar conditions are unfavorable or meteorological conditions are unsuitable, electricity generation and revenue from 
wind and solar energy facilities may be substantially below our expectations. The electricity produced, production tax credits 
received,  and  revenues  generated  by  a  wind  or  solar  energy  facility  are  highly  dependent  on  suitable  wind  conditions  and 
associated weather conditions, which are variable and beyond our control. We base our decisions about which wind and solar 
projects to build or acquire as well as our electricity generation estimates, in part, on the findings of long-term wind and other 
meteorological  studies  conducted  on  the  project  site  and  its  region;  however,  the  unpredictable  nature  of  wind  and  solar 
conditions,  weather  and  meteorological  conditions  can  result  in  material  deviations  from  these  studies  and  our  expectations. 
Furthermore, components of our systems could be damaged by severe weather, such as hailstorms, lightning or tornadoes. In 
addition,  replacement  and  spare  parts  for  key  components  may  be  difficult  or  costly  to  acquire  or  may  be  unavailable. 
Unfavorable  wind  and  solar  conditions,  weather  or  changes  to  meteorological  patterns  could  impair  the  effectiveness  of  our 
electric  generation  facility  assets,  reduce  their  output  beneath  their  rated  capacity  or  require  shutdown  of  key  equipment, 
impeding operation of our wind energy facilities or lead to an impairment of assets.

The construction, operation and maintenance of our electric generation facilities or investment in facilities are subject to 
operational risks that could adversely affect our financial position, results of operations and cash flows. 

The  construction  and  operation  of  generating  facilities  involves  many  risks,  including  the  performance  by  key  contracted 
suppliers  and  maintenance  providers;  increases  in  the  costs  for  or  limited  availability  of  key  materials,  supplies,  labor  and 
services; start-up operations risks; breakdown or failure of facilities; curtailment of facilities by counterparties; the dependence 
on the availability of wind resources; or the impact of unusual, adverse weather conditions or other natural events, as well as the 
risk of performance below expected levels of output or efficiency. Some of our facilities contain older generating equipment, 
which  even  if  maintained  in  accordance  with  good  engineering  practices,  may  require  significant  capital  expenditures  to 
continue  operating  at  peak  efficiency.  We  could  be  subject  to  costs  associated  with  any  unexpected  failure  to  produce  and 
deliver  power,  including  failure  caused  by  breakdown  or  forced  outage,  as  well  as  the  repair  of  damage  to  facilities  due  to 
storms, natural disasters, wars, sabotage, terrorist acts and other catastrophic events. 

The price of electricity may be volatile, which may impact results of operations at ALLETE Clean Energy wind energy 
facilities under contracts with customer and industrial (C&I) customers.

Unusual, adverse weather conditions or other natural events and different settlement prices between hub and node can cause 
volatility  in  market  prices  for  electricity  and  adversely  affect  our  financial  position,  results  of  operations  and  cash  flows. 
ALLETE Clean Energy’s power sales agreements with C&I customers at its Diamond Spring and Caddo wind energy facilities 
are contracts for differences where power is delivered to the market, a fixed price is paid by the customers to ALLETE Clean 
Energy,  and  differences  between  the  market  price  and  the  fixed  price  are  paid  to  or  received  from  the  customers.  Certain 
contracts also settle with the market at the hub price whereas ALLETE Clean Energy settles with the customer at the node price 
which  can  vary  significantly  based  on  multiple  factors.  These  settlement  provisions  can  result  in  an  adverse  impact  on  our 
financial position, results of operations and cash flows when market prices are volatile.

As contracts with counterparties expire, we may not be able to replace them with agreements on similar terms or divest 
the related assets at a profit.

ALLETE Clean Energy is party to PSAs that expire in various years between 2024 and 2039. These PSA expirations are prior 
to the end of the estimated useful lives of the respective wind energy facilities. If, for any reason, ALLETE Clean Energy is 
unable to enter into new agreements with existing or new counterparties on similar terms once the current agreements expire, 
sell  energy  in  the  wholesale  market  resulting  in  similar  revenue,  or  enter  into  a  contract  to  sell  the  facility  at  a  profit,  our 
financial  position,  results  of  operations  and  cash  flows  could  be  adversely  affected,  which  includes  potential  impairment  of 
property, plant and equipment.

Counterparties  to  turbine  and  other  generation  supply,  service  and  maintenance,  or  power  sale  agreements  may  not 
fulfill their obligations.

Our  businesses  are  party  to  turbine  and  other  generation  supply  agreements,  service  and  maintenance  agreements,  and  PSAs 
under various durations with a limited number of creditworthy counterparties. If, for any reason, any of the counterparties under 
these agreements do not fulfill their related contractual obligations, and we are unable to mitigate non-performance by a key 
supplier  or  maintenance  provider  or  remarket  PSA  energy  resulting  in  similar  revenue,  our  financial  position,  results  of 
operations and cash flows could be adversely affected.

ALLETE  has  a  significant  amount  of  goodwill.  A  determination  that  goodwill  has  been  impaired  could  result  in  a 
significant non-cash charge to earnings.

We had approximately $155 million of goodwill recorded on our Consolidated Balance Sheet as of December 31, 2022 related 
to  New  Energy.  If  we  change  our  business  strategy,  fail  to  deliver  on  our  projected  results  or  if  market  or  other  conditions 
adversely  affect  the  operations  of  New  Energy,  we  may  be  required  to  record  an  impairment  charge.  Declines  in  projected 
operating cash flows at New Energy could also result in an impairment charge. An impairment charge would result in a non-
cash charge to earnings that could have an adverse effect on our results of operations.

BNI  Energy  may  be  adversely  impacted  by  its  exposure  to  customer  concentration,  and  environmental  laws  and 
regulations.

BNI  Energy  sells  lignite  coal  to  two  electric  generating  cooperatives,  Minnkota  Power  and  Square  Butte,  and  could  be 
adversely impacted if these customers were unable or unwilling to fulfill their related contractual obligations, or change the way 
in  which  they  operate  their  generating  facilities.  In  addition,  BNI  Energy  and  its  customers  may  be  adversely  impacted  by 
existing  or  new  environmental  laws  and  regulations  which  could  have  an  adverse  effect  on  our  financial  position,  results  of 
operations  and  cash  flows.  In  addition,  insurance  companies  have  decreased  the  available  coverage  for  policy  holders  in  the 
mining industry, impacting the availability of coverage, and leading to higher deductibles and premiums.

Real estate market conditions where our legacy Florida real estate investment is located may deteriorate.

The Company’s strategy related to the real estate assets of ALLETE Properties incorporates the possibility of a bulk sale of its 
entire portfolio, in addition to sales over time, however, adverse market conditions could impact the timing of land sales, which 
could result in little to no sales, while still incurring operating expenses such as community development district assessments 
and property taxes, resulting in net operating losses at ALLETE Properties. Furthermore, weak market conditions could put the 
properties  at  risk  for  an  impairment  charge.  An  impairment  charge  would  result  in  a  non-cash  charge  to  earnings  that  could 
have an adverse effect on our results of operations.

Entity-wide Risks

We could be materially adversely affected by health epidemics, pandemics and other outbreaks.

Health  epidemics,  pandemics  and  other  outbreaks,  as  well  as  the  related  federal  and  state  government  responses,  can  have 
widespread  impacts  on  the  economy  and  on  our  employees,  customers,  contractors  and  suppliers,  such  as  those  experienced 
from the ongoing COVID-19 pandemic. There may be uncertainty regarding the length of time an epidemic, pandemic or other 
outbreak will last, how they will evolve, or the extent and duration of any measures attempted to try and contain them.

Item 1A. Risk Factors (Continued)
Entity-wide Risks (Continued)

A disruption of economic activity or an extended disruption of economic activity may lead to adverse impacts on our taconite, 
paper, pulp and secondary wood products, and pipeline customers’ operations including reduced production or the temporary 
idling or indefinite shutdown of facilities, which would result in lower sales and revenue from these customers. A disruption in 
capital  markets  could  lead  to  increased  borrowing  costs  or  adversely  impact  our  ability  to  access  capital  markets  or  other 
financing sources, which would adversely affect our ability to maintain our businesses or to implement our business plans. An 
epidemic, pandemic or other outbreak may also result in a disruption to our supply chains which could adversely impact our 
operations and capital projects resulting in project and operational delays, project cancellations, lower returns on projects and 
cost increases. 

Despite any efforts made to mitigate the impacts on the Company of an epidemic, pandemic or other outbreak, their ultimate 
impact  also  depends  on  factors  beyond  our  control,  including  their  duration  and  severity  as  well  as  governmental  and  third-
party actions taken to contain their spread and mitigate their public health effects. As a result, we cannot predict the ultimate 
impact  of  an  epidemic,  pandemic  or  other  outbreak,  such  as  the  ongoing  COVID-19  pandemic  and  whether  it  will  have  a 
material impact on our liquidity, financial position, results of operations and cash flows.

We rely on access to financing sources and capital markets. If we do not have access to capital on acceptable terms or 
are unable to obtain capital when needed, our ability to execute our business plans, make capital expenditures or pursue 
other strategic actions that we may otherwise rely on for future growth would be adversely affected.

We  rely  on  access  to  financing  sources  and  the  capital  markets,  on  acceptable  terms  and  at  reasonable  costs,  as  sources  of 
liquidity  for  capital  requirements  not  satisfied  by  our  cash  flows  from  operations.  Rising  interest  rates,  inflation  and  market 
disruptions or a downgrade of our credit ratings may increase the cost of borrowing or adversely affect our ability to access and 
finance in the capital markets or to access other financing sources such as tax equity financing. Such disruptions or causes of a 
downgrade could include but are not limited to: weakening of the Company’s cash flow metrics; a loss of, or a reduction in 
sales  to,  our  taconite,  paper  and  pipeline  customers  if  we  are  unable  to  offset  the  related  lost  margins;  weaker  operating 
performance;  adverse  regulatory  outcomes;  disproportionate  increase  in  the  contribution  to  net  income  from  ALLETE  Clean 
Energy and our Corporate and Other businesses as compared to that from our Regulated Operations; deteriorating economic or 
capital market conditions; or volatility in commodity prices.  

If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain 
our  businesses  or  to  implement  our  business  plans  would  be  adversely  affected.  This  would  include  our  ability  to  make  the 
significant  capital  expenditures  planned  in  order  to  achieve  Minnesota  Power’s  clean-energy  transition  plans.  (See  Item  7. 
Capital Requirements.)

A  deterioration  in  general  economic  conditions,  an  inflationary  environment  or  supply  chain  disruptions  may  have 
adverse impacts on our financial position, results of operations and cash flows.

If  economic  conditions  deteriorate,  we  experience  an  inflationary  environment  or  supply  chains  are  disrupted  on  a  national, 
regional  or  global  level,  it  may  have  a  negative  impact  on  our  customers  and  the  Company’s  financial  position,  results  of 
operations and cash flows. This impact may include volatility and unpredictability in the demand for the products and services 
offered by our businesses, the loss of existing customers, tempered growth strategies, customer production cutbacks, customer 
bankruptcies and increases in costs for or limited availability of key materials, supplies, labor and services for our operations 
and  capital  projects.  An  uncertain  economy  could  also  adversely  affect  expenses  including  pension  costs,  interest  costs,  and 
uncollectible accounts, or lead to reductions in the value of certain real estate and other investments. 

Our utility infrastructure and generating facilities, ongoing and future capital and development projects, and other operations 
require  components,  supplies,  materials,  labor  and  services  sourced  from  suppliers  or  providers  who,  in  turn,  may  source 
components from their suppliers. A shortage of key components, supplies, materials, labor or services in which an alternative 
supplier  or  provider  is  not  identified  could  significantly  impact  project  plans  or  our  operations.  Such  impacts  could  include 
project  delays,  including  potential  for  project  cancellation,  lower  project  returns,  increased  costs  or  the  inability  to  provide 
service to customers, which could adversely impact our results of operations, financial condition or cash flows.

Our  businesses,  investments  and  customers  are  subject  to  extensive  state  and  federal  legislation  and  regulation, 
compliance with which could have an adverse effect on our businesses.

Our businesses, investments and customers are subject to, and affected by, extensive state and federal legislation and regulation. 
If it was determined that our businesses failed to comply with applicable laws and regulations, we could become subject to fines 
or  penalties  or  be  required  to  implement  additional  compliance  measures  or  actions,  the  cost  of  which  could  be  material. 
Adoption  of  new  laws,  rules,  regulations,  principles,  or  practices  by  federal  and  state  agencies,  or  changes  to  or  a  failure  to 
comply with current laws, rules, regulations, principles, or practices and their interpretations, could have an adverse effect on 
our financial position, results of operations and cash flows.

The inability to attract and retain a qualified workforce including, but not limited to, executive officers, key employees 
and employees with specialized skills, could have an adverse effect on our operations.

The success of our business heavily depends on the leadership of our executive officers and key employees to implement our 
business  strategy.  The  inability  to  maintain  a  qualified  workforce,  including,  but  not  limited  to,  executive  officers,  key 
employees and employees with specialized skills, may negatively affect our ability to service our existing or new customers, or 
successfully  manage  our  business  or  achieve  our  business  objectives.  Personnel  costs  may  increase  due  to  competitive 
pressures, inflation or terms of collective bargaining agreements with union employees.

Market  performance  and  other  changes  could  decrease  the  value  of  pension  and  other  postretirement  benefit  plan 
assets, which may result in significant additional funding requirements and increased annual expenses.

The performance of the capital markets impacts the values of the assets that are held in trust to satisfy future obligations under 
our pension and other postretirement benefit plans. We have significant obligations to these plans and the trusts hold significant 
assets. These assets are subject to market fluctuations and will yield uncertain returns, which may fall below our projected rates 
of return. A decline in the market value of the pension and other postretirement benefit plan assets would increase the funding 
requirements under our benefit plans if asset returns do not recover. Additionally, our pension and other postretirement benefit 
plan liabilities are sensitive to changes in interest rates. As interest rates decrease, the liabilities increase, potentially increasing 
benefit expense and funding requirements. Our pension and other postretirement benefit plan costs are generally recoverable in 
our  electric  rates  as  allowed  by  our  regulators  or  through  our  cost-plus  fixed  fee  coal  supply  agreements  at  BNI  Energy; 
however, there is no certainty that regulators will continue to allow recovery of these rising costs in the future.

We are exposed to significant reputational risk.

The  Company  could  suffer  negative  impacts  to  its  reputation  as  a  result  of  operational  incidents,  violations  of  corporate 
compliance policies, regulatory violations, operations that produce or enable the production of GHG emissions or other events 
which  may  result  in  negative  customer  perception,  increased  regulatory  oversight,  and  negative  consequences  to  our  credit 
ratings and ability to access capital, each of which could have an adverse effect on our financial position, results of operations 
and cash flows. 

We  are  subject  to  physical  and  financial  risks  associated  with  climate  change  and  other  catastrophic  events,  such  as 
natural disasters and acts of war.

Catastrophic events at or near Company facilities and equipment on which the Company depends upon or that otherwise impact 
the Company such as fires, wildfires, including the impact to Company facilities and operations or potential liability if caused 
by Company equipment, earthquakes, explosions, and floods, severe weather, such as ice storms, hailstorms, or tornadoes or 
similar  occurrences,  as  well  as  acts  of  war,  could  adversely  affect  the  Company’s  facilities,  operations,  financial  position, 
results of operations and cash flows. Although the Company has contingency plans and employs crisis management to respond 
and  recover  operations  in  the  event  of  a  severe  disruption  resulting  from  a  catastrophic  event,  these  measures  may  not  be 
successful.  Furthermore,  despite  these  measures,  if  a  catastrophic  event  were  to  occur,  our  financial  position,  results  of 
operations and cash flows could be adversely affected.

Entity-wide Risks (Continued)

The  scientific  community  generally  accepts  that  emissions  of  GHG  are  linked  to  global  climate  change.  Physical  risks  of 
climate  change,  such  as  more  frequent,  longer  duration  or  more  extreme  weather  events,  changes  in  temperature  and 
precipitation  patterns,  increased  risk  of  wildfires,  changes  to  ground  and  surface  water  availability,  and  other  related 
phenomena, could affect some, or all, of our operations. Severe weather or other natural disasters could be destructive, which 
could result in increased costs or limit the availability of key materials, supplies, labor and services used in our operations or to 
respond to damaged facilities. An extreme weather event can also directly affect our capital assets, causing disruption in service 
to customers due to facility outages, downed wires and poles or damage to other operating equipment. 

Climate-related  risks  that  could  adversely  affect  our  financial  position  and  results  of  operations  include  effects  of 
environmental- or economic-based laws, regulations, incentives or initiatives designed to reduce the quantity or impact of GHG 
emissions,  the  ability  of  our  regulated  businesses  to  obtain  rate  adjustments  to  recover  costs  and  investments  to  implement 
clean-energy transition plans, or disruptions to the economy or energy markets caused by climate change. This includes the risk 
of laws or regulations that create mandates that do not allow for a transition that protects the safety, reliability or affordability of 
energy for our customers, are implemented before cost-effective technology is developed and regulatory policy is established, 
or  require  the  electric  sector  to  decarbonize  faster  than  other  sectors  and  ahead  of  our  current  goal  to  deliver  100  percent 
carbon-free  energy  to  customers  by  2050.  Additionally,  restrictions  on  land  use,  wildlife  impacts,  and  other  environmental 
regulations could affect the siting, construction and operation of new or existing generation and transmission facilities needed to 
transition to lower-carbon generation sources.

These all have the potential to adversely affect our business and operations.

We are vulnerable to acts of terrorism or cybersecurity attacks.

Our operations may be targets of terrorist activities or cybersecurity attacks, which could disrupt our ability to provide utility 
service at our regulated utilities, develop or operate our renewable energy projects at ALLETE Clean Energy, or operate our 
other businesses. The impacts may also impair the fulfillment of critical business functions, negatively impact our reputation, 
subject us to litigation or increased regulation, or compromise sensitive, confidential and other data.

There have been cybersecurity attacks on U.S. energy infrastructure in the past and there may be such attacks in the future. Our 
generation,  transmission  and  distribution  facilities,  information  technology  systems  and  other  infrastructure  facilities  and 
systems could be direct targets of, or otherwise be materially adversely affected by such activities. Hacking, computer viruses, 
terrorism,  theft  and  sabotage  could  impact  our  systems  and  facilities,  or  those  of  third  parties  on  which  we  rely,  which  may 
disrupt our operations.

Our  businesses  require  the  continued  operation  of  sophisticated  custom-developed,  purchased,  and  leased  information 
technology systems and network infrastructure as well as the collection and retention of personally identifiable information of 
our  customers,  shareholders  and  employees.  Although  we  maintain  security  measures  designed  to  prevent  cybersecurity 
incidents and protect our information technology and control systems, network infrastructure and other assets, our technology 
systems,  or  those  of  third  parties  on  which  we  rely,  may  be  vulnerable  to  disability,  failures  or  unauthorized  access  due  to 
hacking,  viruses,  acts  of  war  or  terrorism  as  well  as  other  causes.  If  those  technology  systems  fail  or  are  breached  and  not 
recovered in a timely manner, we may be unable to perform critical business functions including effectively maintaining certain 
internal controls over financial reporting, our reputation may be negatively impacted, we may become subject to litigation or 
increased  regulation,  and  sensitive,  confidential  and  other  data  could  be  compromised.  If  our  business  were  impacted  by 
terrorist  activities  or  cybersecurity  attacks,  such  impacts  could  have  an  adverse  effect  on  our  financial  position,  results  of 
operations and cash flows.

We maintain insurance against some, but not all, of the risks and uncertainties we face.

We  maintain  insurance  against  some,  but  not  all,  of  the  risks  and  uncertainties  we  face.  The  occurrence  of  these  risks  and 
uncertainties, if not fully covered by insurance, could have a material effect on our financial position, results of operations and

Government  challenges  to  our  tax  positions,  as  well  as  tax  law  changes  and  the  inherent  difficulty  in  quantifying 
potential  tax  effects  of  our  operations  and  business  decisions,  could  adversely  affect  our  results  of  operations  and 
liquidity.

We  are  required  to  make  judgments  regarding  the  potential  tax  effects  of  various  financial  transactions  and  our  ongoing 
operations  in  order  to  estimate  our  obligations  to  taxing  authorities.  The  obligations,  which  include  income  taxes  and  taxes 
other  than  income  taxes,  involve  complex  matters  that  ultimately  could  be  litigated.  We  also  estimate  our  ability  to  use  tax 
benefits,  including  those  in  the  form  of  carryforwards  and  tax  credits  that  are  recorded  as  deferred  tax  assets  on  our 
Consolidated Balance Sheet. A disallowance of some or all of these tax benefits could have an adverse impact on our financial 
position, results of operations and cash flows.

We  are  currently  utilizing,  and  plan  to  utilize  in  the  future,  our  carryforwards  and  tax  credits  to  reduce  our  income  tax 
obligations. If we cannot generate enough taxable income in the future to utilize all of our carryforwards and tax credits before 
they expire, we may incur adverse charges to earnings.

If federal or state tax authorities deny any deductions or tax credits, negatively change existing tax laws or policies, or fail to 
extend or renew policies beneficial to the Company, such as those for renewable energy production tax credits, our financial 
position, results of operations and cash flows may be adversely impacted.

Performance Graph.

The  following  graph  compares  ALLETE’s  cumulative  Total  Shareholder  Return  on  its  common  stock  with  the  cumulative 
return of the S&P 500 Index and the Philadelphia Utility Index. The S&P 500 Index is a capitalization-weighted index of 500 
stocks designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 
stocks  representing  all  major  industries.  Because  this  composite  index  has  a  broad  industry  base,  its  performance  may  not 
closely track that of a composite index comprised solely of electric utilities. The Philadelphia Utility Index is a capitalization-
weighted index of 20 utility companies involved in the generation of electricity.

The calculations assume a $100 investment on December 31, 2017, and reinvestment of dividends.

Overview

Basis of Presentation. We present two reportable segments: Regulated Operations and ALLETE Clean Energy. Our segments 
were determined in accordance with the guidance on segment reporting. We measure performance of our operations through 
budgeting and monitoring of contributions to consolidated net income by each business segment. 

Regulated  Operations  includes  our  regulated  utilities,  Minnesota  Power  and  SWL&P,  as  well  as  our  investment  in  ATC,  a 
Wisconsin-based  regulated  utility  that  owns  and  maintains  electric  transmission  assets  in  portions  of  Wisconsin,  Michigan, 
Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 
150,000  retail  customers.  Minnesota  Power  also  has  14  non-affiliated  municipal  customers  in  Minnesota.  SWL&P  is  a 
Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and 
water  service  in  northwestern  Wisconsin  to  approximately  15,000  electric  customers,  13,000  natural  gas  customers  and 
10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state 
and federal regulatory authorities. (See Note 4. Regulatory Matters.)

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean 
Energy currently owns and operates, in seven states, more than 1,200 MW of nameplate capacity wind energy generation with a 
majority contracted under PSAs of various durations. In addition, ALLETE Clean Energy also engages in the development of 
wind energy facilities to operate under long-term PSAs or for sale to others upon completion. ALLETE Clean Energy currently 
has approximately 100 MW of wind energy facilities under contract to be sold to others.

Corporate and Other is comprised of New Energy, a renewable development company; our investment in Nobles 2, an entity 
that owns and operates a 250 MW wind energy facility in southwestern Minnesota; South Shore Energy, our non-rate regulated, 
Wisconsin  subsidiary  developing  NTEC,  an  approximately  600  MW  proposed  combined-cycle  natural  gas-fired  generating 
facility;  BNI  Energy,  our  coal  mining  operations  in  North  Dakota;  ALLETE  Properties,  our  legacy  Florida  real  estate 
investment; other business development and corporate expenditures; unallocated interest expense; a small amount of non-rate 
base generation; land holdings in Minnesota; and earnings on cash and investments.

ALLETE  is  incorporated  under  the  laws  of  Minnesota.  Our  corporate  headquarters  are  in  Duluth,  Minnesota.  Statistical 
information  is  presented  as  of  December  31,  2022,  unless  otherwise  indicated.  All  subsidiaries  are  wholly-owned  unless 
otherwise  specifically  indicated.  References  in  this  report  to  “we,”  “us”  and  “our”  are  to  ALLETE  and  its  subsidiaries, 
collectively.

2022 Financial Overview

The  following  net  income  discussion  summarizes  a  comparison  of  the  year  ended  December  31,  2022  to  the  year  ended 
December 31, 2021. 

Net  income  attributable  to  ALLETE  in  2022  was  $189.3  million,  or  $3.38  per  diluted  share,  compared  to  $169.2  million,  or 
$3.23  per  diluted  share,  in  2021.  Net  income  in  2022  included  higher  earnings  at  Minnesota  Power  resulting  from  the 
implementation of interim rates on January 1, 2022, net of interim rate reserves, and also included net income of $7.8 million 
from New Energy, which was acquired in April 2022. These increases were partially offset by lower earnings from ALLETE 
Clean Energy reflecting challenges under the Caddo and Diamond Spring wind energy facilities’ power sales agreements and 
additional losses related to the sale of the Northern Wind project. Net income in 2021 included South Shore Energy’s sale of a 
portion  of  its  interest  in  NTEC  to  Basin  Electric  Cooperative  and  the  resulting  recognition  of  an  approximately  $8.5  million 
after-tax gain, or $0.16 per share, related to prior development costs and risks incurred. Net income in 2021 also included an 
approximately $5 million after-tax, or $0.10 per share, negative impact related to ALLETE Clean Energy’s Diamond Spring 
wind energy facility due to an extreme winter storm event in the southwest United States in February 2021. Earnings per share 
dilution in 2022 was $0.23 due to additional shares of common stock outstanding as of December 31, 2022. 

Regulated Operations net income attributable to ALLETE was $149.9 million in 2022, compared to $129.1 million in 2021. 
Net income at Minnesota Power was higher than 2021 primarily due to the implementation of interim rates on January 1, 2022, 
net  of  interim  rate  reserves.  This  increase  was  partially  offset  by  higher  costs  under  a  PPA  with  Manitoba  Hydro,  higher 
operating and maintenance expense, and lower kWh sales to industrial customers. Our after-tax equity earnings in ATC were 
lower than 2021 primarily due to period over period changes in ATC’s estimate of a refund liability related to the appeals court 
decision on MISO return on equity complaints. (See Note 6. Equity Investments.) 

ALLETE Clean Energy net income attributable to ALLETE was $16.3 million in 2022 compared to $26.3 million in 2021. 
Net income in 2022 reflected challenges under the Caddo and Diamond Spring wind energy facilities’ power sales agreements 
resulting from extreme market volatility and transmission congestion in the Southwest Power Pool. Net income in 2022 also 
included additional losses related to the sale of the Northern Wind project. Net income in 2021 included an approximately $5 
million after-tax negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme 
winter storm event in the southwest United States in February 2021.

Corporate and Other net income attributable to ALLETE was $23.1 million in 2022 compared to $13.8 million in 2021. Net 
income  in  2022  reflects  net  income  from  New  Energy  of  $7.8  million,  which  included  a  $8.3  million  after-tax  expense  as  a 
result of purchase price accounting related to projects under development at the time of acquisition. Net income in 2022 also 
reflects higher earnings from our investment in Nobles 2 due to higher wind resources in 2022, higher land sales at ALLETE 
Properties, earnings from Minnesota solar projects placed into service in 2022 and lower income taxes. These increases were 
partially offset by transaction costs of $2.7 million after-tax related to the acquisition of New Energy, and higher other expenses 
compared to 2021. Net income in 2021 included South Shore Energy’s sale of a portion of its interest in NTEC to Basin which 
resulted in the recognition of an approximately $8.5 million after-tax gain related to prior development costs and risks incurred.

Operating  Revenue  –  Utility  increased  $31.4  million  from  2021  primarily  due  to  the  implementation  of  interim  rates  at 
Minnesota  Power  on  January  1,  2022,  as  well  as  increased  recoveries  under  the  Minnesota  conservation  improvement 
program  and  higher  gas  sales.  These  increases  were  partially  offset  by  lower  revenue  from  kWh  sales  and  lower  fuel 
adjustment clause recoveries.

Interim  retail  rate  revenue  of  $85.5  million  was  collected  in  2022,  which  was  partially  offset  by  an  interim  rate  refund 
reserve of approximately $18 million due to the regulatory outcome of the MPUC’s decision in Minnesota Power’s 2022 
general  rate  case.  In  addition,  Minnesota  Power  recorded  a  charge  of  approximately  $8  million  pre-tax  to  write  off  the 
deferred portion of residential customer interim rates. Minnesota Power also recorded additional revenue of approximately 
$9 million pre-tax for an increase in expected recoveries under its cost recovery riders. (See Note 4. Regulatory Matters.)

Conservation  improvement  program  recoveries  increased  $5.9  million  from  2021  primarily  due  to  an  increase  in  related 
expenditures. (See Operating Expenses - Operating and Maintenance.)

Gas sales at SWL&P increased $4.6 million as a result of colder weather and higher gas prices in 2022 compared to 2021. 
(See Fuel, Purchased Power and Gas – Utility.)

Lower kWh sales reduced revenue $27.4 million from 2021 reflecting lower sales to industrial customers and other power 
suppliers, partially offset by higher sales to residential and commercial customers as well as higher pricing on sales to other 
power  suppliers.  Sales  to  residential  and  commercial  customers  increased  from  2021  primarily  due  to  colder  weather  in 
2022 compared to 2021. Sales to industrial customers decreased primarily due to lower sales to taconite customers resulting 
from  less  taconite  production  in  2022  compared  to  2021,  reflecting  Cliffs’  Northshore  mine  being  temporarily  idled  in 
2022.  (See  Outlook  -  Customers  -  Northshore  Mining.)  Sales  to  other  power  suppliers,  which  are  sold  at  market-based 
prices into the MISO market on a daily basis or through PSAs of various durations, decreased in 2022 compared to 2021 
primarily due to additional kWh sales made in 2021 to mitigate the uncertainty of customers’ energy needs and potential 
load loss due to the COVID-19 pandemic.

Revenue  from  electric  sales  to  taconite  customers  accounted  for  32  percent  of  regulated  operating  revenue  in  2022 
(33  percent  in  2021).  Revenue  from  electric  sales  to  paper,  pulp  and  secondary  wood  product  customers  accounted  for 
5 percent of regulated operating revenue in 2022 (5 percent in 2021). Revenue from electric sales to pipelines and other 
industrial customers accounted for 10 percent of regulated operating revenue in 2022 (9 percent in 2021).

Fuel adjustment clause revenue decreased $24.1 million primarily due to lower kWh sales, partially offset by higher fuel 
and purchased power costs attributable to retail and municipal customers. (See Fuel, Purchased Power and Gas – Utility.) 
Fuel  adjustment  clause  revenue  in  2021  also  reflected  a  $5  million  charge  recorded  in  2021  resulting  from  the  MPUC’s 
decision  to  order  refunds  in  Minnesota  Power’s  fuel  adjustment  clause  filing  covering  the  period  July  2018  through 
December 2019. (See Note 4. Regulatory Matters.)

Operating Expenses increased $5.5 million from 2021.

Operating  and  Maintenance  expense  increased  $23.3  million,  or  11  percent,  from  2021  primarily  due  to  higher 
conservation improvement program expenses, professional services and materials purchased for generation facilities, labor 
expenses  and  higher  vegetation  management  expenses.  These  increases  were  partially  offset  by  lower  pension  and  other 
postretirement  benefit  expenses.  In  addition,  2022  included  rate  case-related  expenses  for  Minnesota  Power’s  rate  case. 
(See Note 4. Regulatory Matters.)

Transmission  Services  –  Utility  expense  increased  $1.4  million,  or  2  percent,  from  2021  primarily  due  to  higher  MISO-
related expense.

Depreciation and Amortization expense increased $1.2 million, or 1 percent, from 2021 primarily due to a higher plant in 
service balance in 2022.

Fuel, Purchased Power and Gas – Utility expense decreased $16.9 million, or 3 percent, from 2021 primarily due to lower 
energy  purchases  due  to  lower  kWh  sales,  partially  offset  by  higher  purchased  power  prices  and  fuel  prices.  Fuel  and 
purchased power expense related to our retail and municipal customers is recovered through the fuel adjustment clause.

Taxes  Other  than  Income  Taxes  decreased  $3.5  million,  or  6  percent,  from  2021  primarily  due  to  lower  property  tax 
expense resulting from an updated estimate of taxable market values and rates in 2022.

Equity Earnings decreased $2.0 million from, or 9 percent, 2021 primarily due to period over period changes in ATC’s 
estimate  of  a  refund  liability  related  to  the  appeals  court  decision  on  MISO  return  on  equity  complaints.  (See  Note  6. 
Equity Investments.)

Other Income increased $3.9 million from 2021  primarily due to lower pension and other postretirement plan non-service 
credits. (See Note 1. Operations and Significant Accounting Policies.)

Operating  Revenue  increased  $31.4  million,  or  36  percent,  from  2021  primarily  due  to  revenue  from  the  closing  of  a 
portion  of  ALLETE  Clean  Energy’s  Northern  Wind  project  in  December  2022.  Operating  revenue  in  2022  was  also 
impacted by lower realized pricing under the Caddo and Diamond Spring wind energy facilities’ power sales agreements 
resulting from extreme market volatility and transmission congestion in the Southwest Power Pool. Operating revenue in 
2021 included the negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility resulting from 
an extreme winter storm event in the southwest United States in February 2021.

Energy’s Northern Wind project.

Cost  of  Sales  -  Non-utility  increased  $53.7  million  from  2021  reflecting  additional  losses  in  2022  related  to  ALLETE 
Clean Energy’s project to repower and sell its Northern Wind project resulting from inflationary increases and significant 
cost pressures. In addition, Cost of Sales – Non-utility in 2022 reflected a $10.2 million reserve in the second quarter of 
2022 related to the sale of the Northern Wind project, which was fully offset by a gain on removal of the PSA liability for 
the  Northern  Wind  project  upon  decommissioning  of  the  wind  energy  facilities.  (See  Other  Income  and  Outlook  – 
ALLETE Clean Energy.)

ALLETE Clean Energy (Continued)

Operating  and  Maintenance  expense  increased  $5.8  million,  or  14  percent,  from  2021  primarily  due  to  operating  and 
maintenance expenses related to the Caddo wind energy facility, which commenced operations in December 2021.

Depreciation  and  Amortization  expense  increased  $9.4  million,  or  19  percent,  from  2021  primarily  due  to  additional 
property,  plant  and  equipment  in  service  related  to  the  Caddo  wind  energy  facility,  which  commenced  operations  in 
December 2021.

Taxes Other Than Income Taxes increased $3.6 million from 2021 primarily due to higher property tax expense related to 
the Caddo wind energy facility, which commenced operations in December 2021.

Other Income increased $10.5 million from 2021 primarily due to a gain on removal of the PSA liability for the Northern 
Wind project upon decommissioning of the wind energy facilities. (See Cost of Sales – Non-utility and Outlook – ALLETE 
Clean Energy.)

Net Loss Attributable to Non-Controlling Interest increased $22.6 million from 2021 reflecting net losses attributable to 
non-controlling  interest  for  the  Caddo  wind  energy  facility  as  well  as  higher  net  losses  attributable  to  non-controlling 
interests for the Glen Ullin and Diamond Spring wind energy facilities resulting from higher wind resources and a higher 
PTC value in 2022 compared to 2021.

Corporate and Other

Operating  Revenue  increased  $88.7  million,  or  85  percent,  from  2021  reflecting  revenue  from  New  Energy,  which  was 
acquired  in  April  2022,  higher  revenue  at  BNI  Energy  which  operates  under  cost-plus  fixed  fee  contracts,  as  a  result  of 
higher expenses in 2022 compared to 2021 and higher land sales at ALLETE Properties compared to 2021.  

Net Income Attributable to ALLETE was $23.1 million in 2022 compared to $13.8 million in 2021. Net income in 2022 
reflects  net  income  from  New  Energy  of  $7.8  million,  which  included  a  $8.3  million  after-tax  expense  as  a  result  of 
purchase price accounting related to projects under development at the time of acquisition. Net income in 2022 also reflects 
higher  earnings  from  our  investment  in  Nobles  2  due  to  higher  wind  resources  in  2022,  higher  land  sales  at  ALLETE 
Properties,  earnings  from  Minnesota  solar  projects  placed  into  service  in  2022  and  lower  income  taxes.  These  increases 
were  partially  offset  by  transaction  costs  of  $2.7  million  after-tax  related  to  the  acquisition  of  New  Energy,  and  higher 
other expenses compared to 2021. Net income in 2021 included South Shore Energy’s sale of a portion of its interest in 
NTEC  to  Basin  which  resulted  in  the  recognition  of  an  approximately  $8.5  million  after-tax  gain  related  to  prior 
development costs and risks incurred.

Income Taxes – Consolidated

For the year ended December 31, 2022, the effective tax rate was a benefit of 31.2 percent (benefit of 24.3 percent for the 
year ended December 31, 2021). The effective tax rate for 2022 was a lower benefit primarily due to lower production tax 
credits, higher pre-tax income and higher net losses attributable to non-controlling interests in subsidiaries. (See Note 11. 
Income Tax Expense.)

2021 Compared to 2020

The  comparison  of  the  results  of  operations  for  the  years  ended  December  31,  2021  and  2020  is  included  in  Management's 
Discussion in the Annual Report on Form 10-K for the year ended December 31, 2021. We have identified an immaterial prior 
period error with respect to the recognition of a non-cash impairment expense for our Northern Wind operating assets in 2020, 
and  the  prior  period  results  have  been  revised  accordingly  for  comparability.  See  Note  1.  Operations  and  Significant 
Accounting Policies for additional information.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with GAAP requires management to make various 
estimates  and  assumptions  that  affect  amounts  reported  in  the  Consolidated  Financial  Statements.  These  estimates  and 
assumptions may be revised, which may have a material effect on the Consolidated Financial Statements. Actual results may 
differ from these estimates and assumptions. These policies are discussed with the Audit Committee of our Board of Directors 
on a regular basis. We believe the following policies are most critical to our business and the understanding of our results of 
operations.

Regulatory Accounting. Our regulated utility operations are subject to accounting standards for the effects of certain types of 
regulation. These standards require us to reflect the effect of regulatory decisions in our financial statements. Regulatory assets 
represent  incurred  costs  that  have  been  deferred  as  they  are  probable  for  recovery  in  customer  rates.  Regulatory  liabilities 
represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been 
incurred.  The  Company  assesses  quarterly  whether  regulatory  assets  and  liabilities  meet  the  criteria  for  probability  of  future 
recovery or deferral. This assessment considers factors such as, but not limited to, changes in the regulatory environment and 
recent rate orders to other regulated entities under the same jurisdiction. If future recovery or refund of costs becomes no longer 
probable, the assets and liabilities would be recognized in current period net income or other comprehensive income. (See Note 
4. Regulatory Matters.)

Pension and Postretirement Health and Life Actuarial Assumptions. We account for our pension and other postretirement 
benefit  obligations  in  accordance  with  the  accounting  standards  for  defined  benefit  pension  and  other  postretirement  plans. 
These standards require the use of several important assumptions, including the expected long-term rate of return on plan assets, 
the discount rate and mortality assumptions, among others, in determining our obligations and the annual cost of our pension 
and other postretirement benefits. In establishing the expected long-term rate of return on plan assets, we determine the long-
term  historical  performance  of  each  asset  class  and  adjust  these  for  current  economic  conditions  while  utilizing  the  target 
allocation  of  our  plan  assets  to  forecast  the  expected  long-term  rate  of  return.  Our  pension  asset  allocation  as  of 
December  31,  2022,  was  approximately  46  percent  equity  securities,  50  percent  fixed  income  and  4  percent  real  estate.  Our 
postretirement health and life asset allocation as of December 31, 2022, was approximately 66 percent equity securities, and 
34  percent  fixed  income.  Equity  securities  consist  of  a  mix  of  market  capitalization  sizes  with  domestic  and  international 
securities. In 2022, we used weighted average expected long-term rates of return of 6.00 percent in our actuarial determination 
of  our  pension  expense  and  5.41  percent  in  our  actuarial  determination  of  our  other  postretirement  expense.  The  actuarial 
determination  uses  an  asset  smoothing  methodology  for  actual  returns  to  reduce  the  volatility  of  varying  investment 
performance over time. We review our expected long-term rate of return assumption annually and will adjust it to respond to 
changing market conditions. A one-quarter percent decrease in the expected long-term rate of return would increase the annual 
expense for pension and other postretirement benefits by approximately $2.2 million, pre-tax.

The discount rate is computed using a bond matching study which utilizes a portfolio of high quality bonds that produce cash 
flows similar to the projected costs of our pension and other postretirement plans. In 2022, we used weighted average discount 
rates  of  3.28  percent  and  3.09  percent  in  our  actuarial  determination  of  our  pension  and  other  postretirement  expense, 
respectively.  We  review  our  discount  rates  annually  and  will  adjust  them  to  respond  to  changing  market  conditions.  A  one-
quarter percent decrease in the discount rate would increase the annual expense for pension and other postretirement benefits by 
approximately $1.0 million, pre-tax.

The mortality assumptions used to calculate our pension and other postretirement benefit obligations as of December 31, 2022, 
considered  a  modified  PRI-2012  mortality  table  and  MP-2021  mortality  projection  scale.  (See  Note  12.  Pension  and  Other 
Postretirement Benefit Plans.)

Valuation of Business Combinations and Resulting Goodwill. When we acquire a business, the assets acquired and liabilities 
assumed are recorded at their respective fair values as of the acquisition date. Determining the fair value of intangible assets 
acquired as part of a business combination requires us to make significant estimates. These estimates may include the amount 
and timing of projected future cash flows, the discount rate used to discount those cash flows to present value, the assessment of 
the asset’s life cycle, and the consideration of legal, technical, regulatory, economic and competitive risks.

Critical Accounting Policies (Continued)

Goodwill. Goodwill is the excess of the purchase price (consideration transferred) over the estimated fair value of the net assets 
of  the  acquired  businesses.  In  accordance  with  GAAP,  goodwill  is  not  amortized.  The  Company  assesses  whether  there  has 
been  an  impairment  of  goodwill  annually  in  the  fourth  quarter  and  whenever  an  event  occurs  or  circumstances  change  that 
would indicate the carrying amount may be impaired. Impairment testing for goodwill is done at the reporting unit level. An 
impairment loss is recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the 
reporting  unit.  The  test  for  impairment  requires  us  to  make  several  estimates  about  fair  value,  most  of  which  are  based  on 
projected  future  cash  flows.  Our  estimates  associated  with  the  goodwill  impairment  test  are  considered  critical  due  to  the 
amount of goodwill recorded on our Consolidated Balance Sheet and the judgment required in determining fair value. The fair 
value  of  the  New  Energy  reporting  unit  was  determined  using  a  discounted  cash  flow  model,  using  significant  assumptions 
which included a discount rate of 14 percent, cash flow forecasts through 2027, industry average gross margins, and a terminal 
growth rate of 3.5 percent. Any forecast contains a degree of uncertainty, and changes in the forecasted cash flows and other 
assumptions  could  significantly  increase  or  decrease  the  calculated  fair  value  of  New  Energy.  The  results  of  our  annual 
impairment test are discussed in Note 1. Operations and Significant Accounting Policies and Note 7. Fair Value in this Form 
10-K. Goodwill was $154.9 million as of December 31, 2022.

Impairment  of  Long-Lived  Assets.  We  review  our  long-lived  assets  for  indicators  of  impairment  in  accordance  with  the 
accounting standards for property, plant and equipment on a quarterly basis.

In accordance with the accounting standards for property, plant and equipment, if indicators of impairment exist, we test our 
long-lived  assets  for  recoverability  by  comparing  the  carrying  amount  of  the  asset  to  the  undiscounted  future  net  cash  flows 
expected to be generated by the asset. Cash flows are assessed at the lowest level of identifiable cash flows. The undiscounted 
future net cash flows are impacted by trends and factors known to us at the time they are calculated and our expectations related 
to:  management’s  best  estimate  of  future  sales  prices;  holding  period  and  timing  of  sales;  method  of  disposition;  and  future 
expenditures necessary to maintain the operations.

Taxation.  We  are  required  to  make  judgments  regarding  the  potential  tax  effects  of  various  financial  transactions  and  our 
ongoing operations to estimate our obligations to taxing authorities. These tax obligations include income taxes and taxes other 
than  income  taxes.  Judgments  related  to  income  taxes  require  the  recognition  in  our  financial  statements  of  the  largest  tax 
benefit of a tax position that is “more-likely-than-not” to be sustained on audit. Tax positions that do not meet the “more-likely-
than-not” criteria are reflected as a tax liability in accordance with the accounting standards for uncertainty in income taxes. We 
record a valuation allowance against our deferred tax assets to the extent it is more-likely-than-not that some portion or all of 
the deferred tax assets will not be realized.

We are subject to income taxes in various jurisdictions. We make assumptions and judgments each reporting period to estimate 
our  income  tax  assets,  liabilities,  benefits  and  expenses.  Judgments  and  assumptions  are  supported  by  historical  data  and 
reasonable projections. Our assumptions and judgments include the application of tax statutes and regulations, and projections 
of  future  federal  taxable  income,  state  taxable  income,  and  state  apportionment  to  determine  our  ability  to  utilize  NOL  and 
credit  carryforwards  prior  to  their  expiration.  Significant  changes  in  assumptions  regarding  future  federal  and  state  taxable 
income or a change in tax rates could require new or increased valuation allowances which could result in a material impact on 
our results of operations.

Outlook

ALLETE is an energy company committed to earning a financial return that rewards our shareholders, allows for reinvestment 
in our businesses, and sustains growth. The Company has a long-term objective of achieving consolidated earnings per share 
growth within a range of 5 percent to 7 percent.

ALLETE  is  predominately  a  regulated  utility  through  Minnesota  Power,  SWL&P,  and  an  investment  in  ATC.  ALLETE’s 
strategy is to remain predominately a regulated utility while investing in ALLETE Clean Energy, New Energy and its Corporate 
and Other businesses to complement its regulated businesses, balance exposure to the utility’s industrial customers, and provide 
potential long-term earnings growth. ALLETE expects net income from Regulated Operations to be approximately 75 percent 
of total consolidated net income in 2023. ALLETE expects its businesses to generally provide regulated, contracted or recurring 
revenues, and to support sustained growth in net income and cash flow.

On  August  16,  2022,  the  Inflation  Reduction  Act  was  signed  into  law.  We  believe  our  businesses  will  benefit  from  certain 
provisions  of  the  legislation  including  from  the  extension  and  transferability  of  production  tax  credits  and  investment  tax 
credits, among others. We do not anticipate any impact from the new alternative minimum tax. We will continue to assess the 
impact of the legislation as additional implementation guidance becomes available.

Minnesota Carbon-Free Legislation. On February 7, 2023, the Minnesota Governor signed into law legislation that updates the 
state’s renewable energy standard and requires Minnesota electric utilities to source retail sales with 100 percent carbon-free 
energy by 2040. The law increases the renewable energy standard from 25 percent renewable by 2025 to 55 percent renewable 
by 2035, and requires investor-owned Minnesota utilities to provide 80 percent carbon-free energy by 2030, 90 percent carbon-
free energy by 2035 and 100 percent carbon-free energy by 2040. The law utilizes renewable energy credits as the means to 
demonstrate  compliance  with  both  the  carbon-free  and  renewable  standards,  includes  an  off-ramp  provision  that  enables  the 
MPUC  to  protect  reliability  and  customer  costs  through  modification  or  delay  of  either  the  renewable  energy  standard,  the 
carbon-free  standard,  or  both,  and  streamlines  development  and  construction  of  wind  energy  projects  and  transmission  in 
Minnesota. The Company is evaluating the law to identify challenges and opportunities it could present. 

Regulated  Operations.  Minnesota  Power’s  long-term  strategy  is  to  be  the  leading  electric  energy  provider  in  northeastern 
Minnesota  by  providing  safe,  reliable  and  cost-competitive  electric  energy,  while  complying  with  environmental  permit 
conditions and renewable energy requirements. Keeping the cost of energy production competitive enables Minnesota Power to 
effectively compete in the wholesale power markets and minimizes retail rate increases to help maintain customer viability. As 
part of maintaining cost competitiveness, Minnesota Power intends to reduce its exposure to possible future carbon and GHG 
legislation  by  reshaping  its  generation  portfolio,  over  time,  to  reduce  its  reliance  on  coal.  Minnesota  Power  has  a  goal  of 
delivering  100  percent  carbon-free  energy  by  2050.  (See  EnergyForward.)  We  will  monitor  and  review  proposed 
environmental regulations and may challenge those that add considerable cost with limited environmental benefit. Minnesota 
Power will continue to pursue customer growth opportunities and cost recovery rider approvals for transmission, renewable and 
environmental investments, as well as work with regulators to earn a fair rate of return.

Regulatory Matters. Entities within our Regulated Operations segment are under the jurisdiction of the MPUC, FERC, PSCW 
and NDPSC. See Note 4. Regulatory Matters for discussion of regulatory matters within these jurisdictions.

2022  Minnesota  General  Rate  Case.  On  November  1,  2021,  Minnesota  Power  filed  a  retail  rate  increase  request  with  the 
MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 
10.25  percent  and  a  53.81  percent  equity  ratio.  On  an  annualized  basis,  the  requested  final  rate  increase  would  generate 
approximately  $108  million  in  additional  revenue.  In  orders  dated  December  30,  2021,  the  MPUC  accepted  the  filing  as 
complete and authorized an annual interim rate increase beginning January 1, 2022, with approximately $80 million expected to 
be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination 
on recovery at the end of the rate case.

Regulatory Matters (Continued)

At a hearing on January 23, 2023, the MPUC made determinations regarding Minnesota Power’s general rate case including 
allowing a return on common equity of 9.65 percent and a 52.50 percent equity ratio. Upon commencement of final rates, we 
expect additional revenue from base rates of approximately $60 million and an additional $10 million in revenue recognized 
under cost recovery riders on an annualized basis, subject to final written order and reconsideration. Final rates are expected to 
commence in the third quarter of 2023; interim rates will be collected through this period with reserves recorded as necessary. 
As a result of the MPUC’s determinations made on January 23, 2023, Minnesota Power has recorded a reserve for an interim 
rate refund of approximately $18 million pre-tax as of December 31, 2022, which is subject to MPUC approval of Minnesota 
Power’s refund calculation. In addition, Minnesota Power recorded a charge of approximately $8 million pre-tax to write-off 
the deferred portion of residential customer interim rates. Minnesota Power also recorded additional revenue of approximately 
$9 million pre-tax for an increase in expected recoveries under its cost recovery riders. Minnesota Power plans to file its next 
rate case in the fourth quarter of 2023.

Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that 
surrounds several reservoirs on its hydroelectric system and is no longer required to maintain its operations. The land has an 
estimated value of approximately $100 million, and Minnesota Power proposed to credit ratepayers the net proceeds from the 
sales  in  a  future  rate  case  or  through  its  renewable  resources  rider  to  mitigate  future  rate  increases.  In  an  order  dated 
November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers subject to 
certain conditions and required compliance filings.

2022 Wisconsin General Rate Case. In 2022, SWL&P filed a rate increase request with the PSCW seeking an average increase 
of 3.6 percent for retail customers. The filing sought an overall return on equity of 10.4 percent and a 55 percent equity ratio. 
On an annualized basis, the requested final rate increase would have generated an estimated $4.3 million in additional revenue. 
In an order dated December 20, 2022, the PSCW approved an annual increase of $3.3 million reflecting a return on equity of 
10.0 percent and 55 percent equity ratio. Final rates went into effect January 1, 2023.

Industrial Customers and Prospective Additional Load

Industrial  Customers.  Electric  power  is  one  of  several  key  inputs  in  the  taconite  mining,  paper,  pulp  and  secondary  wood 
products, pipeline and other industries. Approximately 52 percent of our regulated utility kWh sales in 2022 (47 percent in 2021 
and 47 percent in 2020) were made to our industrial customers. We expect industrial sales of approximately 6.5 million MWh 
in 2023 (6.7 million MWh in 2022 and 7.2 million in 2021). (See Item 1. Business – Regulated Operations – Electric Sales / 
Customers.)

Taconite.  Minnesota  Power’s  taconite  customers  are  capable  of  producing  up  to  approximately  41  million  tons  of  taconite 
pellets annually. Taconite pellets produced in Minnesota are primarily shipped to North American steel making facilities that 
are  part  of  the  integrated  steel  industry,  which  continue  to  lead  the  world  in  environmental  performance  among  steelmaking 
countries. According to the U.S. Department of Energy, steel production in the U.S. is the most energy efficient of any major 
steel  producing  country.  Steel  produced  from  these  North  American  facilities  is  used  primarily  in  the  manufacture  of 
automobiles,  appliances,  tubular  applications  for  all  industries,  and  in  the  construction  industry.  Steel  is  also  a  critical 
component of the clean energy transformation underway today. Meeting the demand for more renewable energy and the need 
for  additional  infrastructure  to  transport  green  energy  from  the  point  of  generation  to  the  end  user  both  require  steel. 
Historically, less than 10 percent of Minnesota taconite production has been exported outside of North America.

There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American 
Iron and Steel Institute, an association of North American steel producers, reported that U.S. raw steel production operated at 
approximately 78 percent of capacity in 2022 (82 percent in 2021 and 68 percent in 2020). The World Steel Association, an 
association  of  steel  producers,  national  and  regional  steel  industry  associations,  and  steel  research  institutes  representing 
approximately 85 percent of world steel production, projected U.S. steel consumption in 2023 will increase by approximately 
2 percent compared to 2022.

Outlook (Continued)
Industrial Customers and Prospective Additional Load (Continued)

Minnesota Power’s taconite customers may experience annual variations in production levels due to such factors as economic 
conditions, short-term demand changes or maintenance outages. We expect taconite production from our taconite customers of 
approximately 33 million tons in 2023. We estimate that a one million ton change in Minnesota Power’s taconite customers’ 
production  would  impact  our  annual  earnings  per  share  by  approximately  $0.04,  net  of  expected  power  marketing  sales  at 
current  prices.  Changes  in  wholesale  electric  prices  or  customer  contractual  demand  nominations  could  impact  this  estimate. 
Minnesota  Power  proactively  sells  power  in  the  wholesale  power  markets  that  is  temporarily  not  required  by  industrial 
customers  to  optimize  the  value  of  its  generating  facilities.  Long-term  reductions  in  taconite  production  or  a  permanent  shut 
down of a taconite customer may lead Minnesota Power to file a general rate case to recover lost revenue. 

USS Corporation. USS Corporation has announced plans to invest approximately $150 million to construct a system dedicated 
to producing direct reduced-grade (DR-grade) pellets at its Keetac plant. USS Corporation broke ground on the project in the 
third quarter of 2022, which is expected to be completed and producing DR-grade pellets in 2024. This will enable the existing 
pelletizing plant to not only create DR-grade pellets for use as a feedstock for a direct reduced iron (DRI) or hot briquetted iron 
(HBI) process that ultimately supplies electric arc furnace steelmaking but also maintains the optionality to continue producing 
blast furnace-grade pellets. USS Corporation’s Minntac and Keetac plants are large power industrial customers of Minnesota 
Power. USS Corporation has the capability to produce approximately 15 million and 5 million tons annually at its Minntac and 
Keetac plants, respectively.

Cleveland-Cliffs,  Inc.  (Cliffs).  In  2020,  Cliffs  announced  that  it  had  completed  the  previously  announced  acquisition  of 
substantially  all  of  the  operations  of  ArcelorMittal  USA  LLC  and  its  subsidiaries.  Cliffs  had  stated  that  upon  closure  of  the 
acquisition, Cliffs would be the largest flat-rolled steel producer and the largest iron ore pellet producer in North America. The 
acquisition  included  ArcelorMittal’s  Minorca  mine  in  Virginia,  Minnesota,  and  its  ownership  share  of  Hibbing  Taconite  in 
Hibbing,  Minnesota,  which  are  both  large  industrial  customers  of  Minnesota  Power.  Cliffs  is  Minnesota  Power’s  largest 
customer.  The  acquisition  has  increased  customer  concentration  risk  for  the  Company  and  could  lead  to  further  capacity 
consolidation for both steel blast furnaces and related Minnesota iron ore production.

Cliffs  completed  construction  of  a  hot  briquetted  iron  production  plant  in  Toledo,  Ohio,  in  2020,  which  has  utilized  direct 
reduced-grade pellets from Northshore Mining. In October 2021, Cliffs indicated it plans to move direct reduced-grade pellet 
production to its Minorca mine and that Northshore Mining would become a “swing facility” due to the higher royalty rates at 
that mine. (See Northshore Mining.).

Northshore Mining. On February 11, 2022, Cliffs announced that with the use of additional scrap in its basic oxygen furnaces, 
its iron ore needs are not as high as before. In determining where to adjust production, Cliffs decided to idle all production at its 
Northshore mine until at least April 2023. Cliffs has also indicated that going forward it will be limiting the tonnage of iron ore 
pellets sold to third parties. Northshore Mining has the capability to produce approximately 6 million tons annually. Minnesota 
Power  has  a  PSA  through  2031  with  Silver  Bay  Power,  which  provides  the  majority  of  the  electric  service  requirements  for 
Northshore Mining. (See Cliffs.)

Silver  Bay  Power.  In  2016,  Minnesota  Power  and  Silver  Bay  Power  entered  into  a  PSA  through  2031.  Silver  Bay  Power 
supplies  approximately  90  MW  of  load  to  Northshore  Mining,  an  affiliate  of  Silver  Bay  Power,  which  had  previously  been 
served  predominately  through  self-generation  by  Silver  Bay  Power.  Starting  in  2016,  Minnesota  Power  supplied  Silver  Bay 
Power  with  at  least  50  MW  of  energy  and  Silver  Bay  Power  had  the  option  to  purchase  additional  energy  from  Minnesota 
Power  as  it  transitioned  away  from  self-generation.  In  2019,  Silver  Bay  Power  ceased  self-generation  and  Minnesota  Power 
began supplying the full energy requirements for Silver Bay Power.

Hibbing  Taconite.  Hibbing  Taconite  is  a  joint  venture  between  subsidiaries  of  Cliffs  (85.3  percent  ownership)  and  USS 
Corporation (14.7 percent ownership). The joint venture is managed by Cliffs and is also a Large Power Customer of Minnesota 
Power.  Hibbing  Taconite  has  the  capability  of  producing  8  million  tons  of  taconite  annually.  Hibbing  Taconite  has  proven 
mineral reserves to support its operations through 2026; and is actively seeking additional mineral reserves to operate beyond 
its currently stated mine life.

Minnesota Sulfate Wild Rice Water Quality Standard. On April 29, 2021, the EPA identified rivers and lakes in Minnesota in 
which wild rice grows that have sulfate levels that exceed Minnesota’s sulfate limit for wild rice waters. On September 1, 2021, 
three additional wild rice waters with sulfate levels that exceed Minnesota’s sulfate limit were identified. The EPA directed the 
MPCA  to  add  these  rivers  and  lakes  to  its  list  of  impaired  waters  which  can  be  used  to  set  limits  in  discharge  permits  for 
industrial activities such as mining. Minnesota Power’s taconite customers could be adversely impacted if they are required to 
significantly reduce sulfate discharges.

Paper, Pulp and Secondary Wood Products. The North American paper and pulp industry continues to face declining demand 
due to the impact of electronic substitution for print and changing customer needs. As a result, certain paper and pulp customers 
have  reduced  their  existing  operations  in  recent  years  and  have  pursued  or  are  pursuing  product  changes  in  response  to  the 
declining demand. The resulting reduction in production capacity outside of Minnesota for certain paper grades has solidified 
our paper customers’ operations, at least for the near term, and as such we expect operating levels in 2023 at the major paper 
and pulp mills we serve to be at similar levels as in 2022. 

ST Paper. In May 2021, ST Paper announced it had completed the purchase of the Duluth Mill from Verso Corporation. ST 
Paper is completing a project at the Duluth Mill to produce tissue. In January 2022, Minnesota Power entered into an electric 
service agreement with ST Paper that would begin Large Power Customer service with a minimum term of six years upon start-
up of operations, which is anticipated in 2023. A petition for approval of the electric service agreement was approved by the 
MPUC  in  May  2022.  Upon  start-up  of  operations,  ST  Paper  will  become  a  Large  Power  Customer  as  we  expect  to  serve 
requirements of at least 10 MW of customer load.

Pipeline and Other Industries.

Cenovus Energy. In 2018, a fire at Cenovus Energy’s refinery in Superior, Wisconsin, which was owned by Husky Energy at 
that time, disrupted operations at the facility. Under normal operating conditions, SWL&P provides approximately 14 MW of 
average  monthly  demand  to  the  refinery  in  addition  to  water  service.  The  facility  remains  at  minimal  operations,  and  the 
refinery is expected to resume normal operations in 2023. 

Prospective Additional Load. Minnesota Power is pursuing new wholesale and retail loads in and around its service territory. 
Currently,  several  companies  in  northeastern  Minnesota  continue  to  progress  in  the  development  of  natural  resource-based 
projects that represent long-term growth potential and load diversity for Minnesota Power. We cannot predict the outcome of 
these projects.

EnergyForward.  Minnesota  Power  is  executing  EnergyForward,  its  strategy  assuring  reliability,  protecting  affordability  and 
further improving environmental performance. The plan includes completed and planned investments in wind, solar, natural gas 
and hydroelectric power, construction of additional transmission capacity, the installation of emissions control technology and 
the idling and retirement of certain coal-fired generating facilities. Minnesota Power has a vision to deliver 100 percent carbon-
free  energy  to  customers  by  2050,  continuing  its  commitment  to  climate,  customers  and  communities  through  its 
EnergyForward strategy. This vision builds on Minnesota Power’s recent achievement of now providing 50 percent renewable 
energy to its customers.

2021 Integrated Resource Plan (IRP). On February 1, 2021, Minnesota Power filed its latest IRP, which was approved by the 
MPUC  in  an  order  dated  January  9,  2023.  The  approved  IRP,  which  reflects  a  joint  agreement  reached  with  various 
stakeholders,  outlines  Minnesota  Power’s  clean-energy  transition  plans  through  2035.  These  plans  include  expanding  its 
renewable  energy  supply,  achieving  coal-free  operations  at  its  facilities  by  2035,  and  investing  in  a  resilient  and  flexible 
transmission and distribution grid. As part of these plans, Minnesota Power anticipates adding up to 700 MW of new wind and 
solar  energy  resources,  and  ceasing  coal  operations  at  Boswell  Units  3  and  4  by  2030  and  2035,  respectively.  Minnesota 
Power’s  plans  recognize  that  advances  in  technology  will  play  a  significant  role  in  completing  its  transition  to  carbon-free 
energy supply, reliably and affordably. Minnesota Power is expected to file its next IRP by March 1, 2025.

In recent years, Minnesota Power has transformed its energy supply from more than a 95 percent reliance on coal to become a 
leader in the nation’s clean-energy transformation. Since 2013, the company has closed or converted seven of its nine coal-fired 
units and added nearly 900 megawatts of renewable energy sources. Additionally, Minnesota Power has been a leader in energy 
conservation, surpassing the state’s conservation goals each year for the past decade.

Nemadji Trail Energy Center (NTEC). In 2017, Minnesota Power submitted a resource package to the MPUC which included 
requesting approval of a natural gas capacity dedication and other affiliated-interest agreements for NTEC, an approximately 
600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly 
owned by Dairyland Power Cooperative, Basin and South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary. 
Minnesota  Power  is  expected  to  purchase  approximately  20  percent  of  the  facility's  output  starting  in  2025  pursuant  to  the 
capacity dedication agreement.

Renewable  Energy.  Minnesota  Power  continues  to  execute  its  renewable  energy  strategy  and  recently  reached  its  goal  of 
supplying 50 percent of its energy by renewable energy sources. Minnesota Power also has a goal of delivering 100 percent 
carbon-free energy by 2050. (See EnergyForward.) 

Minnesota Power has approved cost recovery riders for certain renewable investments and expenditures as well as investments 
and expenditures related to compliance with the Minnesota Solar Energy Standard. The cost recovery riders allow Minnesota 
Power to charge retail customers on a current basis for the costs of certain renewable and solar investments and expenditures 
plus a return on the capital invested. (See Note 4. Regulatory Matters.) 

Wind  Energy.  Minnesota  Power’s  wind  energy  facilities  consist  of  Bison  (497  MW)  located  in  North  Dakota,  and  Taconite 
Ridge  (25  MW)  located  in  northeastern  Minnesota.  Minnesota  Power  also  has  two  long-term  wind  energy  PPAs  with  an 
affiliate of NextEra Energy, Inc. to purchase the output from Oliver Wind I (50 MW) and Oliver Wind II (48 MW) located in 
North Dakota.

Minnesota Power uses the 465-mile, 250-kV DC transmission line that runs from Center, North Dakota, to Duluth, Minnesota, 
to transport wind energy from North Dakota while gradually phasing out coal-based electricity delivered to its system over this 
transmission line from Square Butte’s lignite coal-fired generating unit. Minnesota Power is currently pursuing a modernization 
and capacity upgrade of its DC transmission system to continue providing reliable operations and additional system capabilities.

Nobles 2 PPA. Minnesota Power has a long-term PPA with Nobles 2 that provides for Minnesota Power to purchase the energy 
and associated capacity from a 250 MW wind energy facility in southwestern Minnesota through 2040. The agreement provides 
for the purchase of output from the facility at fixed energy prices. There are no fixed capacity charges, and Minnesota Power 
will only pay for energy as it is delivered. (See Corporate and Other – Investment in Nobles 2.)

Manitoba  Hydro.  Minnesota  Power  has  two  long-term  PPAs  with  Manitoba  Hydro.  The  first  PPA  provides  for  Minnesota 
Power to purchase 250 MW of capacity and energy from Manitoba Hydro through May 2035. The second PPA provides for 
Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro through June 2040.  (See Note 9. Commitments, 
Guarantees and Contingencies.)

Solar  Energy.  Minnesota  Power’s  solar  energy  supply  consists  of  Camp  Ripley,  a  10  MW  solar  energy  facility  at  the  Camp 
Ripley Minnesota Army National Guard base and training facility near Little Falls, Minnesota, and a community solar garden in 
northeastern  Minnesota,  which  is  comprised  of  a  1  MW  solar  array  owned  and  operated  by  a  third  party  with  the  output 
purchased by Minnesota Power and a 40 kW solar array that is owned and operated by Minnesota Power. SWL&P also plans to  
construct a 470 kW solar array in 2023 as part of a community solar garden in Superior, Wisconsin, which was approved by the 
PSCW in October 2020.

In  June  2020,  Minnesota  Power  filed  a  proposal  with  the  MPUC  to  accelerate  its  plans  for  purchasing  solar  energy  from 
approximately  20  MW  of  solar  energy  projects  in  Minnesota  which  was  approved  in  a  June  2021  order.  These  solar  energy 
projects  will  be  constructed  and  owned  through  an  ALLETE  subsidiary  with  an  estimated  investment  of  $40  million. 
Construction of these solar energy projects commenced in 2022 and will be operational in 2023.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid 
or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, 
investments to enhance our own transmission facilities, investments in other transmission assets (individually or in combination 
with others) and our investment in ATC. See Item 1. Business – Regulated Operations and Note 9. Commitments, Guarantees 
and Contingencies.

Transmission (Continued)

North Plains Connector Development Agreement. ALLETE and Grid United LLC, an independent transmission company, have 
signed a memorandum of understanding to explore transmission opportunities, with plans to execute a North Plains Connector 
development  agreement  in  the  first  half  of  2023.  The  project  is  a  new,  approximately  385-mile  high-voltage  direct-current 
(HVDC)  transmission  line  from  central  North  Dakota,  to  Colstrip,  Montana  that  will  be  the  first  transmission  connection 
between three regional U.S. electric energy markets— MISO, the Western Interconnection and the Southwest Power Pool. This 
new  link,  open  to  all  sources  of  electric  generation,  would  create  3,000  MW  of  transfer  capacity  between  the  middle  of  the 
country  and  the  West  Coast,  easing  congestion  on  the  transmission  system,  increasing  resiliency  and  reliability  in  all  three 
energy markets, and enabling fast sharing of renewable energy across a vast area with diverse weather patterns. The project is 
expected to cost approximately $2.5 billion. ALLETE expects to pursue at least 35 percent ownership and would oversee the 
line’s  operation.  The  companies  expect  project  permitting  to  start  in  2023  as  they  work  toward  an  in-service  date  of  2029, 
pending regulatory approvals. 

Duluth Loop Reliability Project. On October 21, 2021, Minnesota Power submitted an application for a certificate of need for 
the  Duluth  Loop  Reliability  Project.  This  transmission  project  was  proposed  to  enhance  reliability  in  and  around  Duluth, 
Minnesota. The project includes the construction of a new 115-kV transmission line; construction of an approximately one-mile 
extension of an existing 230-kV transmission line; and upgrades to several substations. A certificate of need and route permit 
are expected in first quarter of 2023. The Duluth Loop Reliability Project is expected to be completed and in service by 2025, 
subject to MPUC approval, with an estimated cost of $50 million to $70 million. 

MISO Long Range Transmission Plan. Minnesota Power and Great River Energy announced on July 25, 2022, their intent to 
build a 150-mile, 345-kV transmission line, connecting northern Minnesota to central Minnesota to support continued reliability 
in  the  Upper  Midwest.  Great  River  Energy,  a  wholesale  electric  power  cooperative,  and  Minnesota  Power  filed  a  Notice  of 
Intent to Construct, Own and Maintain the transmission line with the MPUC on August 1, 2022. This joint project is part of a 
portfolio  of  transmission  projects  approved  on  July  25,  2022,  by  MISO,  as  part  of  the  first  phase  of  its  Long  Range 
Transmission Plan. Planning for the $970 million transmission line is in its early stages with the route anticipated to generally 
follow existing rights of way in an established power line corridor. The two utilities expect to seek a combined Certificate of 
Need  and  Route  Permit  from  the  MPUC.  The  MPUC  will  determine  the  final  route  as  well  as  cost  recovery  for  Minnesota 
Power’s  approximately  50  percent  estimated  share  of  the  project.  Subject  to  regulatory  approvals,  the  transmission  line  is 
expected to be in service in 2030.

Investment in ATC. ATC’s most recent 10-year transmission assessment, which covers the years 2022 through 2031, identifies a 
need for between $5.1 billion and $6.2 billion in transmission system investments. These investments by ATC, if undertaken, 
are expected to be funded through a combination of internally generated cash, debt and investor contributions. As opportunities 
arise, we plan to make additional investments in ATC through general capital calls based upon our pro rata ownership interest 
in ATC.

ALLETE Clean Energy. 

ALLETE Clean Energy will pursue growth through acquisitions or project development. ALLETE Clean Energy is targeting 
acquisitions of existing operating portfolios which have a mix of long-term PSAs in place and/or available for repowering and 
recontracting.  Further,  ALLETE  Clean  Energy  will  evaluate  actions  that  will  lead  to  the  addition  of  complimentary  clean 
energy  products  and  services.  At  this  time,  ALLETE  Clean  Energy  is  focused  on  actions  that  will  optimize  its  clean  energy 
project  portfolio  of  operating  and  development  projects,  which  may  include  recontracting,  repowering,  entering  into 
partnerships and divestitures along with continued acquisitions or development of new projects including wind, solar, energy 
storage or storage ready facilities across North America.

Portions  of  our  ALLETE  Clean  Energy  business  are  experiencing  return  pressures  that  are  impacting  our  earnings  per  share 
growth  from  increased  competition,  and  lower  forward  price  curves,  as  a  growing  amount  of  investment  capital  is  being 
directed  into  wind  generation  opportunities.  In  addition,  current  and  potential  new  project  developments  can  be  negatively 
affected by a lower ALLETE stock price, which may result in such projects not being accretive, or otherwise unable to satisfy 
our financial objectives criteria to proceed. In response to these market pressures, we are actively evaluating additional growth 
opportunities  to  deliver  more  comprehensive  clean  energy  solutions  for  customers  at  ALLETE  Clean  Energy,  which  may 
include wind, solar, storage solutions, and related energy infrastructure investments and services. We believe that the renewable 
energy industry is entering a new phase of growth and that we are well-positioned to serve customers and drive future growth at 
ALLETE. ALLETE Clean Energy will continue to optimize its existing wind energy facility portfolio, seek development of its 
remaining safe harbor inventory of tax credit qualified turbines, and explore other renewable energy opportunities to expand its 
service offerings to further enhance its growth and profitability.

Outlook (Continued)
ALLETE Clean Energy (Continued)

In  May  2021,  ALLETE  Clean  Energy  announced  that  it  acquired  the  rights  to  the  approximately  92  MW  Red  Barn  wind 
development  project  and  the  approximately  68  MW  Whitetail  renewable  development  project  in  southwestern  Wisconsin. 
ALLETE Clean Energy also signed an asset sale agreement for the completed Red Barn wind project with Wisconsin Public 
Service Corporation and Madison Gas and Electric Company. At a hearing in January 2022, the PSCW approved the sale of the 
Red Barn wind project, which is expected to close in 2023, subject to completion of construction and receipt of permits.

ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and 
geographic diversity. The current operating portfolio is subject to typical variations in seasonal wind with higher wind resources 
typically available in the winter months. The majority of its planned maintenance leverages this seasonality and is performed 
during lower wind periods. ALLETE Clean Energy’s current operating portfolio is as follows:

negotiate an agreement on a new PSA.

Non-cash  amortization  to  revenue  recognized  by  ALLETE  Clean  Energy  relates  to  the  amortization  of  differences  between 
contract  prices  and  estimated  market  prices  on  assumed  PSAs.  As  part  of  wind  energy  facility  acquisitions,  ALLETE  Clean 
Energy  assumed  various  PSAs  that  were  above  or  below  estimated  market  prices  at  the  time  of  acquisition;  the  resulting 
differences between contract prices and estimated market prices are amortized to revenue over the remaining PSA term. Non-
cash  amortization  is  expected  to  be  approximately  $5  million  in  2023,  $6  million  annually  in  2024  through  2027,  and 
decreasing thereafter through 2032.

South  Shore  Energy.  South  Shore  Energy,  ALLETE’s  non-rate  regulated,  Wisconsin  subsidiary,  is  developing  NTEC,  an 
approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which 
will  be  jointly  owned  by  Dairyland  Power  Cooperative,  Basin  and  South  Shore  Energy.  Minnesota  Power  is  expected  to 
purchase  approximately  20  percent  of  the  facility's  output  starting  in  2027  pursuant  to  a  capacity  dedication  agreement. 
Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost 
is  estimated  to  be  approximately  $700  million,  of  which  South  Shore  Energy’s  portion  is  expected  to  be  approximately 
$150  million.  South  Shore  Energy’s  portion  of  NTEC  project  costs  incurred  through  December  31,  2022,  is  approximately 
$7 million.

BNI Energy. In 2022, BNI Energy sold 3.7 million tons of coal (3.9 million tons in 2021) and anticipates 2023 sales will be 
higher than  2022. BNI Energy operates under cost-plus fixed fee agreements extending through December 31, 2037.

ALLETE  Properties.  Our  strategy  incorporates  the  possibility  of  a  bulk  sale  of  the  entire  ALLETE  Properties  portfolio. 
Proceeds  from  a  bulk  sale  would  be  strategically  deployed  to  support  growth  initiatives  at  our  Regulated  Operations  and 
ALLETE Clean Energy. ALLETE Properties also continues to pursue sales of individual parcels over time and will continue to 
maintain key entitlements and infrastructure.

Income Taxes

ALLETE’s  aggregate  federal  and  multi-state  statutory  tax  rate  is  approximately  28  percent  for  2022.  ALLETE  also  has  tax 
credits  and  other  tax  adjustments  that  reduce  the  combined  statutory  rate  to  the  effective  tax  rate.  These  tax  credits  and 
adjustments historically have included items such as production tax credits, excess deferred taxes, non-controlling interests in 
subsidiaries, as well as other items. The annual effective rate can also be impacted by such items as changes in income before 
income  taxes,  state  and  federal  tax  law  changes  that  become  effective  during  the  year,  business  combinations,  tax  planning 
initiatives and resolution of prior years’ tax matters. We expect our effective tax rate to be a benefit of approximately 5 percent 
for 2023 primarily due to federal production tax credits as a result of wind energy generation and non-controlling interests in 
subsidiaries. We also expect that our effective tax rate will be lower than the combined statutory rate over the next 10 years due 
to production tax credits attributable to our wind energy generation.

Operating Activities. Cash provided by operating activities was lower in 2022 compared to 2021. Cash provided by operating 
activities  in  2022  reflected  higher  payments  for  inventories,  net  of  customer  deposits  received,  compared  to  2021  primarily 
related to ALLETE Clean Energy’s Northern Wind and Red Barn projects. This decrease was partially offset by the timing of 
recovery under the fuel adjustment clause.

Cash provided by operating activities was lower in 2021 compared to 2020. Cash from operating activities in 2021 included 
lower  net  income  and  higher  payments  for  inventories  compared  to  2020,  and  was  negatively  impacted  by  the  timing  of 
recovery under the fuel adjustment clause.

Investing Activities. Cash used in investing activities was lower in 2022 compared to 2021. Cash used for investing activities in 
2022 reflected lower additions to property, plant and equipment and lower payments for equity method investments compared 
to 2021. These decreases were partially offset by cash payments for the acquisition of New Energy.

Cash used in investing activities was lower in 2021 compared to 2020. Cash used for investing activities in 2021 reflected lower 
additions to property, plant and equipment and lower payments for equity method investments compared to 2020.

Financing  Activities.  Cash  provided  by  financing  activities  was  lower  in  2022  compared  to  2021  primarily  due  to  higher 
repayments of short-term and long-term debt and higher dividends on common stock in 2022. These decreases were partially 
offset by higher proceeds from the issuance of common stock, higher proceeds from issuance of short-term and long-term debt, 
and higher proceeds from non-controlling interest in 2022. 

Cash  provided  by  financing  activities  was  lower  in  2021  compared  to  2020  primarily  due  to  lower  proceeds  from  non-
controlling  interest  in  subsidiaries  and  higher  repayments  of  short-term  and  long-term  debt  in  2021.  These  decreases  were 
partially offset by higher proceeds from the issuance of common stock and higher proceeds from the issuance of short-term and 
long-term debt in 2021.

Liquidity and Capital Resources (Continued)

Working Capital. Additional working capital, if and when needed, generally is provided by consolidated bank lines of credit 
and the issuance of securities, including long-term debt, common stock and commercial paper. As of December 31, 2022, we 
had  consolidated  bank  lines  of  credit  aggregating  $475.7  million  ($432.0  million  as  of  December  31,  2021),  most  of  which 
expire  in  January  2026.  We  had  $32.8  million  outstanding  in  standby  letters  of  credit  and  $31.3  million  outstanding  draws 
under  our  lines  of  credit  as  of  December  31,  2022  ($31.5  million  in  standby  letters  of  credit  and  $159.7  million  outstanding 
draws as of December 31, 2021). We also have other credit facility agreements in place that provide the ability to issue up to 
$252.0 million in standby letters of credit. As of December 31, 2022, we had $245.4 million outstanding in standby letters of 
credit under these agreements.

In  addition,  as  of  December  31,  2022,  we  had  2.9  million  original  issue  shares  of  our  common  stock  available  for  issuance 
through  Invest  Direct  and  2.1  million  original  issue  shares  of  common  stock  available  for  issuance  through  a  distribution 
agreement with Lampert Capital Markets. (See Securities.) The amount and timing of future sales of our securities will depend 
upon market conditions and our specific needs.

Securities. We entered into a distribution agreement with Lampert Capital Markets, in 2008, as amended most recently in 2020, 
with respect to the issuance and sale of up to an aggregate of 13.6 million shares of our common stock, without par value, of 
which 2.1 million shares remain available for issuance as of December 31, 2022. For the year ended December 31, 2022, no 
shares of common stock were issued under this agreement (0.8 million shares for net proceeds of $51.0 million in 2021; none in 
2020). 

During the year ended December 31, 2022, we issued 0.3 million shares of common stock through Invest Direct, the Employee 
Stock  Purchase  Plan  and  the  Retirement  Savings  and  Stock  Ownership  Plan,  resulting  in  net  proceeds  of  $16.2  million 
(0.3 million shares for net proceeds of $18.9 million in 2021; 0.4 million shares for net proceeds of $18.1 million in 2020). See 
Note 10. Common Stock and Earnings Per Share for additional detail regarding ALLETE’s equity securities.

On  April  5,  2022,  ALLETE  issued  and  sold  approximately  3.7  million  shares  of  ALLETE  common  stock.  Net  proceeds  of 
approximately $224 million were received from the sale of shares. Proceeds were used primarily to fund the acquisition of New 
Energy and capital investments at ALLETE Clean Energy.

Financial Covenants. See Note 8. Short-Term and Long-Term Debt for information regarding our financial covenants.

Pension  and  Other  Postretirement  Benefit  Plans.  Management  considers  various  factors  when  making  funding  decisions, 
such as regulatory requirements, actuarially determined minimum contribution requirements and contributions required to avoid 
benefit restrictions for the defined benefit pension plans. For the year ended December 31, 2022, we made no contributions to 
the  defined  benefit  pension  plans.  On  January  17,  2023,  we  contributed  $6.5  million  in  cash  to  the  defined  benefit  pension 
plans. We do not expect to make any further contributions to our defined benefit pension plans in 2023, and we do not expect to 
make any contributions to our other postretirement benefit plans in 2023. (See Note 10. Common Stock and Earnings Per Share 
and Note 12. Pension and Other Postretirement Benefit Plans.)

Off-Balance  Sheet  Arrangements.  Off-balance  sheet  arrangements  are  discussed  in  Note  9.  Commitments,  Guarantees  and 
Contingencies.

Contractual Obligations and Commercial Commitments. ALLETE has contractual obligations and other commitments that 
will need to be funded in the future, in addition to its capital expenditure programs. Material contractual obligations and other 
commitments are as follows:

Long-Term  Debt.  ALLETE  has  material  long-term  debt  obligations,  including  long-term  debt  due  within  one  year.  These 
obligations include the principal amount of bonds, notes and loans which are recorded on the Consolidated Balance Sheet, plus 
interest. (See Note 8. Short-Term and Long-Term Debt.)

Pension and Other Postretirement Benefit Plans. Pension and other postretirement benefit plan obligations include the current 
estimate  of  future  benefit  payments.  Pension  contributions  are  dependent  on  several  factors  including  realized  asset 
performance, future discount rate and other actuarial assumptions, Internal Revenue Service and other regulatory requirements, 
and contributions required to avoid benefit restrictions for the pension plans. Funding for the other postretirement benefit plans 
is  impacted  by  realized  asset  performance,  future  discount  rate  and  other  actuarial  assumptions,  and  utility  regulatory 
requirements. Our obligations are estimates and will change based on actual market performance, changes in interest rates and 
any changes in governmental regulations. (See Note 12. Pension and Other Postretirement Benefit Plans.)

Operating  Lease  Obligations.  ALLETE  has  certain  operating  lease  obligations  for  the  minimum  payments  required  under 
various  lease  agreements  which  are  recorded  on  the  Consolidated  Balance  Sheet.  (See  Note  1.  Operations  and  Significant 
Accounting Policies.)  

Easement  Obligations.  ALLETE  has  easement  obligations  for  the  minimum  payments  required  under  our  land  easement 
agreements at our wind energy facilities. (See Note 9. Commitments, Guarantees and Contingencies.)

PPA Obligations. PPA obligations represent our Square Butte, Manitoba Hydro and other PPAs. (See Note 9. Commitments, 
Guarantees and Contingencies.)

Other  Purchase  Obligations.  ALLETE  has  other  purchase  obligations  covering  our  minimum  purchase  commitments  under 
coal  supply  and  rail  contracts,  and  long-term  service  agreements  for  wind  energy  facilities.  (See  Note  9.  Commitments, 
Guarantees and Contingencies.)

Credit Ratings. Access to reasonably priced capital markets is dependent in part on credit and ratings. Our securities have been 
rated  by  S&P  and  by  Moody’s.  Rating  agencies  use  both  quantitative  and  qualitative  measures  in  determining  a  company’s 
credit  rating.  These  measures  include  business  risk,  liquidity  risk,  competitive  position,  capital  mix,  financial  condition, 
predictability  of  cash  flows,  management  strength  and  future  direction.  Some  of  the  quantitative  measures  can  be  analyzed 
through  a  few  key  financial  ratios,  while  the  qualitative  ones  are  more  subjective.  Our  current  credit  ratings  are  listed  in  the 
following table:

The disclosure of these credit ratings is not a recommendation to buy, sell or hold our securities. Ratings are subject to revision 
or  withdrawal  at  any  time  by  the  assigning  rating  organization.  Each  rating  should  be  evaluated  independently  of  any  other 
rating. 

Common Stock Dividends. ALLETE is committed to providing a competitive dividend to its shareholders while at the same 
time funding its growth. ALLETE’s long-term objective is to maintain a dividend payout ratio similar to our peers and provide 
for future dividend increases. Our targeted payout range is between 60 percent and 70 percent. In 2022, we paid out 77 percent 
(78 percent in 2021; 78 percent in 2020) of our per share earnings in dividends. On February 3, 2023, our Board of Directors 
declared a dividend of $0.6775 per share, which is payable on March 1, 2023, to shareholders of record at the close of business 
on February 15, 2023.

(a) These capital expenditures are part of Minnesota Power’s clean-energy transition plans, which include its vision to deliver 100 percent 
carbon-free  energy  to  customers  by  2050,  as  detailed  in  Minnesota  Power’s  latest  IRP,  which  was  approved  by  the  MPUC  in 
January  2023.  These  capital  expenditures  are  dependent  on  successful  requests  for  proposal  by  Minnesota  Power.  (See  Outlook  – 
EnergyForward.) 

(b) Capital expenditures in 2023 do not include costs related to ALLETE Clean Energy’s  project to develop and sell the 92 MW Red Barn 

project as these projects will be sold upon completion. (See Outlook – ALLETE Clean Energy.) 

(c) Our portion of estimated capital expenditures for construction of NTEC, an approximately 600 MW proposed combined-cycle natural 
gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and 
South Shore Energy.

(d) These amounts do not include any capital expenditures related to the North Plains Connector Development Agreement. (See Outlook – 

Transmission.)

We are well positioned to meet our financing needs due to adequate operating cash flows, available additional working capital 
and access to capital markets. We will finance capital expenditures from a combination of internally generated funds, debt and 
equity  issuance  proceeds.  We  intend  to  maintain  a  capital  structure  with  capital  ratios  near  current  levels.  (See  Capital 
Structure.) 

Environmental and Other Matters

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of 
regulatory  changes  to  the  Clean  Air  Act,  the  Clean  Water  Act  and  various  waste  management  requirements  have  been 
promulgated  by  both  the  EPA  and  state  authorities  over  the  past  several  years.  Minnesota  Power’s  facilities  are  subject  to 
additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to 
reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy 
during rulemaking implementation. (See Note 9. Commitments, Guarantees and Contingencies.)

Market Risk (Continued)

INTEREST RATE RISK

We are exposed to risks resulting from changes in interest rates as a result of our issuance of variable rate debt. We manage our 
interest rate risk by varying the issuance and maturity dates of our fixed rate debt, limiting the amount of variable rate debt, and 
continually monitoring the effects of market changes in interest rates. We may also enter into derivative financial instruments, 
such as interest rate swaps, to mitigate interest rate exposure. The following table presents the long-term debt obligations and 
the corresponding weighted average interest rate as of December 31, 2022:

Interest rates on variable rate long-term debt are reset on a periodic basis reflecting prevailing market conditions. Based on the 
variable  rate  debt  outstanding  as  of  December  31,  2022,  an  increase  of  100  basis  points  in  interest  rates  would  impact  the 
amount of pre-tax interest expense by $2.2 million. This amount was determined by considering the impact of a hypothetical 
100 basis point increase to the average variable interest rate on the variable rate debt outstanding as of December 31, 2022.

COMMODITY PRICE RISK

Our  regulated  utility  operations  incur  costs  for  power  and  fuel  (primarily  coal  and  related  transportation)  in  Minnesota,  and 
power and natural gas purchased for resale in our regulated service territory in Wisconsin. Minnesota Power’s exposure to price 
risk for these commodities is significantly mitigated by the current ratemaking process and regulatory framework, which allows 
recovery of fuel costs in excess of those included in base rates or distribution of savings in fuel costs to ratepayers. SWL&P’s 
exposure  to  price  risk  for  natural  gas  is  significantly  mitigated  by  the  current  ratemaking  process  and  regulatory  framework, 
which allows the commodity cost to be passed through to customers. We seek to prudently manage our customers’ exposure to 
price risk by entering into contracts of various durations and terms for the purchase of power and coal and related transportation 
costs (Minnesota Power) and natural gas (SWL&P).

POWER MARKETING

Minnesota Power’s power marketing activities consist of: (1) purchasing energy in the wholesale market to serve its regulated 
service  territory  when  energy  requirements  exceed  generation  output;  and  (2)  selling  excess  available  energy  and  purchased 
power. From time to time, Minnesota Power may have excess energy that is temporarily not required by retail and municipal 
customers  in  our  regulated  service  territory.  Minnesota  Power  actively  sells  any  excess  energy  to  the  wholesale  market  to 
optimize the value of its generating facilities.

We are exposed to credit risk primarily through our power marketing activities. We use credit policies to manage credit risk, 
which includes utilizing an established credit approval process and monitoring counterparty limits.

Item 9A. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

As  of  December  31,  2022,  evaluations  were  performed,  under  the  supervision  and  with  the  participation  of  management, 
including  our  principal  executive  officer  and  principal  financial  officer,  on  the  effectiveness  of  the  design  and  operation  of 
ALLETE’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 
1934  (Exchange  Act).  Based  upon  those  evaluations,  our  principal  executive  officer  and  principal  financial  officer  have 
concluded  that  such  disclosure  controls  and  procedures  are  effective  to  provide  assurance  that  information  required  to  be 
disclosed  in  ALLETE’s  reports  filed  or  submitted  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported 
within the time periods specified in the SEC’s rules and forms, and such information is accumulated and communicated to our 
management,  including  our  principal  executive  officer  and  principal  financial  officer,  to  allow  timely  decisions  regarding 
required disclosure.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term 
is defined in Exchange Act Rule 13a-15(f) or 15d-15(f). Under the supervision and with the participation of our management, 
including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our 
internal  control  over  financial  reporting  based  on  the  Internal  Control  –  Integrated  Framework  (framework)  issued  by  the 
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  our  evaluation  under  the  framework,  our 
management concluded that our internal control over financial reporting was effective as of December 31, 2022.

The  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of  December  31,  2022,  has  been  audited  by 
PricewaterhouseCoopers  LLP,  an  independent  registered  public  accounting  firm,  as  stated  in  their  report  which  is  included 
herein.

On April 15, 2022, the Company completed the acquisition of New Energy. As a result, management has excluded New Energy 
from our assessment of internal control over financial reporting. New Energy is a wholly-owned subsidiary whose total assets 
and total revenues represent 1 percent and 5 percent, respectively, of the related Consolidated Financial Statement amounts as 
of and for the year ended December 31, 2022.

Changes in Internal Controls

There has been no change in our internal control over financial reporting that occurred during our most recent fiscal quarter that 
has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of ALLETE, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheet of ALLETE, Inc. and its subsidiaries (the “Company”) as of 
December 31, 2022 and 2021, and the related consolidated statements of income, of comprehensive income, of equity and of 
cash flows for each of the three years in the period ended December 31, 2022, including the related notes and financial 
statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial 
statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2022, 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 consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2022 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, 2022, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated 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 Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express 
opinions on the Company’s consolidated financial statements and 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 consolidated 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 consolidated financial statements included performing procedures to assess the risks of material misstatement 
of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. 
Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated 
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 consolidated 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.

As described in Management’s Report on Internal Control over Financial Reporting, management has excluded New Energy 
from its assessment of internal control over financial reporting as of December 31, 2022, because it was acquired by the 
Company in a purchase business combination during 2022. We have also excluded New Energy from our audit of internal 
control over financial reporting. New Energy is a wholly-owned subsidiary whose total assets and total revenues excluded from 
management’s assessment and our audit of internal control over financial reporting represent 1% and 5%, respectively, of the 
related consolidated financial statement amounts as of and for the year ended December 31, 2022.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) 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 

ALLETE, Inc. 2022 Form 10-K
67

expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (iii) 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.

Critical Audit Matters

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

Accounting for the Effects of Regulatory Matters

As described in Note 4 to the consolidated financial statements, the Company’s regulated utility operations are subject to 
accounting standards for the effects of certain types of regulation. As of December 31, 2022, there was $467 million of 
regulatory assets and $550 million of regulatory liabilities recorded. Regulatory assets represent incurred costs that have been 
deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to 
customers and amounts collected in rates for which the related costs have not yet been incurred. Management assesses quarterly 
whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. As disclosed by 
management, these standards require the Company to reflect the effect of regulatory decisions in its financial statements. This 
assessment considers factors such as, but not limited to, changes in the regulatory environment and recent rate orders to other 
regulated entities under the same jurisdiction. If future recovery or refund of costs becomes no longer probable, the assets and 
liabilities would be recognized in current period net income or other comprehensive income.  

The principal consideration for our determination that performing procedures relating to the Company’s accounting for the 
effects of regulatory matters is a critical audit matter is the significant judgment by management in determining the 
recoverability of costs; this in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures 
and evaluating audit evidence obtained related to the recoverability of costs.    

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to 
management’s implementation of new regulatory orders, changes to existing regulatory orders, and assessing the recoverability 
of costs. These procedures also included, among others, evaluating (i) the reasonableness of management’s assessment of 
impacts arising from correspondence with regulators and changes in laws and regulations, (ii) management’s judgments related 
to the recoverability of regulatory assets and the establishment of regulatory liabilities, and (iii) the sufficiency of the 
disclosures in the consolidated financial statements. Testing the regulatory assets and liabilities involved considering the 
provisions and formulas outlined in rate orders, other regulatory correspondence, and application of relevant regulatory 
precedents.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

Financial  Statement  Preparation.  References  in  this  report  to  “we,”  “us,”  and  “our”  are  to  ALLETE  and  its  subsidiaries, 
collectively.  We  prepare  our  financial  statements  in  conformity  with  GAAP.  These  principles  require  management  to  make 
informed  judgments,  best  estimates,  and  assumptions  that  affect  the  reported  amounts  of  assets,  liabilities,  revenue  and 
expenses. Actual results could differ from those estimates. The presentation of certain prior period amounts on the Consolidated 
Financial Statements have been adjusted for comparative purposes.

Subsequent  Events.  The  Company  performed  an  evaluation  of  subsequent  events  for  potential  recognition  and  disclosure 
through the time of the financial statements issuance. 

Principles  of  Consolidation.  Our  Consolidated  Financial  Statements  include  the  accounts  of  ALLETE,  all  of  our 
majority-owned subsidiary companies and variable interest entities of which ALLETE is the primary beneficiary. All material 
intercompany balances and transactions have been eliminated in consolidation.

Variable  Interest  Entities.  The  accounting  guidance  for  “Variable  Interest  Entities”  (VIE)  is  a  consolidation  model  that 
considers if a company has a variable interest in a VIE. A VIE is a legal entity that possesses any of the following conditions: 
the  entity’s  equity  at  risk  is  not  sufficient  to  permit  the  legal  entity  to  finance  its  activities  without  additional  subordinated 
financial  support,  equity  owners  are  unable  to  direct  the  activities  that  most  significantly  impact  the  legal  entity’s  economic 
performance (or they possess disproportionate voting rights in relation to the economic interest in the legal entity), or the equity 
owners lack the obligation to absorb the legal entity’s expected losses or the right to receive the legal entity’s expected residual 
returns. Entities are required to consolidate a VIE when it is determined that they have a controlling financial interest in a VIE 
and therefore are the primary beneficiary of that VIE, as defined by the accounting guidance for “Variable Interest Entities.” In 
determining whether ALLETE is the primary beneficiary of a VIE, management considers whether ALLETE has the power to 
direct the most significant activities of the VIE and is obligated to absorb losses or receive the expected residual returns that are 
significant to the VIE. The accounting guidance for VIEs applies to certain ALLETE Clean Energy wind energy facilities and 
our investment in Nobles 2. (See Tax Equity Financing.)

Business  Segments.  We  present  two  reportable  segments:  Regulated  Operations  and  ALLETE  Clean  Energy.  Our  segments 
were determined in accordance with the guidance on segment reporting. We measure performance of our operations through 
budgeting and monitoring of contributions to consolidated net income by each business segment. 

Regulated  Operations  includes  our  regulated  utilities,  Minnesota  Power  and  SWL&P,  as  well  as  our  investment  in  ATC,  a 
Wisconsin-based  regulated  utility  that  owns  and  maintains  electric  transmission  assets  in  portions  of  Wisconsin,  Michigan, 
Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 
150,000  retail  customers.  Minnesota  Power  also  has  14  non-affiliated  municipal  customers  in  Minnesota.  SWL&P  is  a 
Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and 
water  service  in  northwestern  Wisconsin  to  approximately  15,000  electric  customers,  13,000  natural  gas  customers  and 
10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state 
and federal regulatory authorities.

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean 
Energy currently owns and operates, in seven states, more than 1,200 MW of nameplate capacity wind energy generation  with 
a majority contracted under PSAs of various durations. In addition, ALLETE Clean Energy also engages in the development of 
wind energy facilities to operate under long-term PSAs or for sale to others upon completion. ALLETE Clean Energy currently 
has approximately 100 MW of wind energy facilities under contract to be sold to others.

NOTE 1.  OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

Corporate and Other is comprised of New Energy, our investment in Nobles 2, South Shore Energy, BNI Energy, ALLETE 
Properties,  other  business  development  and  corporate  expenditures,  unallocated  interest  expense,  a  small  amount  of  non-rate 
base generation, land holdings in Minnesota, and earnings on cash and investments.

New  Energy  is  a  renewable  energy  development  company  with  a  primary  focus  on  solar  and  storage  facilities  while  also 
offering comprehensive operations, maintenance and asset management services.

Our investment in Nobles 2 represents a 49 percent equity interest in Nobles 2, the entity that owns and operates a 250 MW 
wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power.

South  Shore  Energy,  ALLETE’s  non-rate  regulated,  Wisconsin  subsidiary,  is  developing  NTEC,  an  approximately  600  MW 
proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned 
by  Dairyland  Power  Cooperative,  Basin  and  South  Shore  Energy.  Minnesota  Power  is  expected  to  purchase  approximately 
20 percent of the facility's output starting in 2027 pursuant to a capacity dedication agreement. Construction of NTEC is subject 
to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately 
$700  million,  of  which  South  Shore  Energy’s  portion  is  expected  to  be  approximately  $150  million.  South  Shore  Energy’s 
portion of NTEC project costs incurred through December 31, 2022, is approximately $7 million.

BNI Energy mines and sells lignite coal to two North Dakota mine-mouth generating units, one of which is Square Butte. In 
2022, Square Butte supplied 50 percent (227.5 MW) of its output to Minnesota Power under long-term contracts. (See Note 9. 
Commitments, Guarantees and Contingencies.)

ALLETE Properties represents our legacy Florida real estate investment. Our strategy incorporates the possibility of a bulk sale 
of the entire ALLETE Properties portfolio. Proceeds from a bulk sale would be strategically deployed to support growth at our 
Regulated  Operations  and  ALLETE  Clean  Energy.  ALLETE  Properties  continues  to  pursue  sales  of  individual  parcels  over 
time and will continue to maintain key entitlements and infrastructure. 

Cash, Cash Equivalents and Restricted Cash. We consider all investments purchased with original maturities of three months 
or less to be cash equivalents. As of December 31, 2022, and 2021, restricted cash amounts included in Prepayments and Other 
on the Consolidated Balance Sheet include collateral deposits required under an ALLETE Clean Energy loan agreement. The 
restricted cash amounts included in Other Non-Current Assets represent collateral deposits required under an ALLETE Clean 
Energy loan agreement and PSAs. The December 31, 2020 amount also includes deposits required under tax equity financing 
agreements.  The  following  table  provides  a  reconciliation  of  cash,  cash  equivalents  and  restricted  cash  reported  within  the 
Consolidated Balance Sheet that aggregate to the amounts presented in the Consolidated Statement of Cash Flows.

(a) The decommissioning of the existing Northern Wind assets resulted in a reclassification from Property, Plant and Equipment – Net to 
Inventories – Net in the second quarter of 2022 as they were repowered and subsequently sold to a subsidiary of Xcel Energy Inc. In the 
third  quarter  of  2022,  safe  harbor  equipment  was  transferred  to  the  project  entity  resulting  in  an  additional  reclassification  from 
Property, Plant and Equipment – Net to Inventories – Net.

(b) Amount reclassified to Current Liabilities resulting from the exercise of an option to buy out a non-controlling interest. 

Accounts Receivable. Accounts receivable are reported on the Consolidated Balance Sheet net of an allowance for doubtful 
accounts.  The  allowance  is  based  on  our  evaluation  of  the  receivable  portfolio  under  current  conditions,  overall  portfolio 
quality, review of specific situations and such other factors that, in our judgment, deserve recognition in estimating losses.

Concentration  of  Credit  Risk.  We  are  subject  to  concentration  of  credit  risk  primarily  as  a  result  of  accounts  receivable. 
Minnesota Power sells electricity to seven Large Power Customers. Receivables from these customers totaled $11.3 million as 
of December 31, 2022 ($7.8 million as of December 31, 2021). Minnesota Power does not obtain collateral to support utility 
receivables,  but  monitors  the  credit  standing  of  major  customers.  In  addition,  Minnesota  Power,  as  permitted  by  the  MPUC, 
requires  its  taconite-producing  Large  Power  Customers  to  pay  weekly  for  electric  usage  based  on  monthly  energy  usage 
estimates,  which  allows  us  to  closely  manage  collection  of  amounts  due.  Minnesota  Power’s  taconite  customers,  which  are 
currently owned by two entities at the end of 2022, accounted for approximately 32 percent of Regulated Operations operating 
revenue and approximately 26 percent of consolidated operating revenue in 2022 (32 percent of Regulated Operations operating 
revenue and 28 percent of consolidated operating revenue in 2021 and 29 percent of Regulated Operations operating revenue 
and 25 percent of consolidated operating revenue in 2020).

Long-Term  Finance  Receivables.  Long-term  finance  receivables  relating  to  our  real  estate  operations  are  collateralized  by 
property  sold,  accrue  interest  at  market-based  rates  and  are  net  of  an  allowance  for  doubtful  accounts.  We  assess  delinquent 
finance receivables by comparing the balance of such receivables to the estimated fair value of the collateralized property. If the 
fair value of the property is less than the finance receivable, we record a reserve for the difference. We estimate fair value based 
on recent property tax assessed values or current appraisals.

Available-for-Sale  Securities.  Available-for-sale  debt  and  equity  securities  are  recorded  at  fair  value.  Unrealized  gains  and 
losses  on  available-for-sale  debt  securities  are  included  in  accumulated  other  comprehensive  income  (loss),  net  of  tax. 
Unrealized gains and losses on available-for-sale equity securities are recognized in earnings. We use the specific identification 
method as the basis for determining the cost of securities sold. 

Inventories – Net. Inventories are stated at the lower of cost or net realizable value. Inventories in our Regulated Operations 
segment  are  carried  at  an  average  cost  or  first-in,  first-out  basis.  Inventories  in  our  ALLETE  Clean  Energy  segment  and 
Corporate and Other businesses are carried at an average cost, first-in, first-out or specific identification basis.

Property,  Plant  and  Equipment.  Property,  plant  and  equipment  are  recorded  at  original  cost  and  are  reported  on  the 
Consolidated  Balance  Sheet  net  of  accumulated  depreciation.  Expenditures  for  additions,  significant  replacements, 
improvements and major plant overhauls are capitalized; maintenance and repair costs are expensed as incurred. Gains or losses 
on  property,  plant  and  equipment  for  Corporate  and  Other  operations  are  recognized  when  they  are  retired  or  otherwise 
disposed. When property, plant and equipment in our Regulated Operations and ALLETE Clean Energy segments are retired or 
otherwise  disposed,  no  gain  or  loss  is  recognized  in  accordance  with  the  accounting  standards  for  component  depreciation 
except  for  certain  circumstances  where  the  retirement  is  unforeseen  or  unexpected.  Our  Regulated  Operations  capitalize 
AFUDC, which includes both an interest and equity component. AFUDC represents the cost of both debt and equity funds used 
to  finance  utility  plant  additions  during  construction  periods.  AFUDC  amounts  capitalized  are  included  in  rate  base  and  are 
recovered  from  customers  as  the  related  property  is  depreciated.  Upon  MPUC  approval  of  cost  recovery,  the  recognition  of 
AFUDC ceases. (See Note 2. Property, Plant and Equipment.)

We believe that long-standing ratemaking practices approved by applicable state and federal regulatory commissions allow for 
the recovery of the remaining book value of retired plant assets. The MPUC order for Minnesota Power’s 2015 IRP directed 
Minnesota Power to retire Boswell Units 1 and 2, which occurred in the fourth quarter of 2018. As part of the 2016 general 
retail rate case, the MPUC allowed recovery of the remaining book value of Boswell Units 1 and 2 through 2022. Minnesota 
Power’s latest IRP, which was approved by the MPUC in an order dated January 9, 2023, includes ceasing coal operations at 
Boswell  Units  3  and  4  by  2030  and  2035,  respectively.  Boswell  Unit  3  and  Unit  4  have  a  net  book  value  of  approximately 
$235 million and $435 million, respectively, as of December 31, 2022. (See Note 4. Regulatory Matters.) Minnesota Power’s 
latest IRP also includes the retirement of Taconite Harbor. As of December 31, 2022, Taconite Harbor had a net book value of 
approximately $25 million. We do not expect to record any impairment charge as a result of these operating changes at Taconite 
Harbor  and  Boswell.  In  addition,  we  expect  to  be  able  to  continue  depreciating  these  assets  for  at  least  their  established 
remaining  useful  lives;  however,  we  are  unable  to  predict  the  impact  of  regulatory  outcomes  resulting  in  changes  to  their 
established remaining useful lives. 

Impairment  of  Long-Lived  Assets.  We  review  our  long-lived  assets  for  indicators  of  impairment  in  accordance  with  the 
accounting standards for property, plant and equipment on a quarterly basis. This includes our property, plant and equipment 
(see Property, Plant and Equipment) and land inventory. Land inventory is accounted for as held for use and is recorded at cost, 
unless the carrying value is determined not to be recoverable in accordance with the accounting standards for property, plant 
and equipment, in which case the land inventory is written down to estimated fair value.

NOTE 1.  OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

In accordance with the accounting standards for property, plant and equipment, if indicators of impairment exist, we test our 
long-lived  assets  for  recoverability  by  comparing  the  carrying  amount  of  the  asset  to  the  undiscounted  future  net  cash  flows 
expected to be generated by the asset. Cash flows are assessed at the lowest level of identifiable cash flows. The undiscounted 
future net cash flows are impacted by trends and factors known to us at the time they are calculated and our expectations related 
to: management’s best estimate of future use; sales prices; holding period and timing of sales; method of disposition; and future 
expenditures necessary to maintain the operations.

We  continue  to  monitor  changes  in  the  broader  energy  markets  along  with  wind  resource  expectations  that  could  indicate 
impairment  at  ALLETE  Clean  Energy  wind  energy  facilities  upon  contract  expirations.  A  decline  in  energy  prices  or  lower 
wind resource expectations could result in a future impairment.

In 2022 and 2021 there were triggering events that indicated an impairment for our property, plant, and equipment at certain 
ALLETE Clean Energy wind energy facilities with expiring PSAs for which a recoverability test was performed indicating that 
the undiscounted cash flows adequately supported the property, plant and equipment book values. As a result, no impairment 
was  recorded  in  2022  and  2021.  In  2020,  there  were  indicators  of  impairment  for  ALLETE  Clean  Energy’s  Northern  Wind 
project. See Immaterial Revision to Prior Period.

Immaterial Revision to Prior Period. We have identified an immaterial prior period error with respect to the recognition of a 
non-cash impairment expense for our Northern Wind operating assets in the fourth quarter of 2020 prior to the execution of the 
purchase and sales agreement for a repower and sale of the wind energy facility. Specifically, the remaining net book value of 
the property, plant and equipment used in the recoverability test was calculated incorrectly. If the net book value would have 
been calculated correctly in the recoverability test, an $8.8 million after-tax impairment expense would have been recognized in 
the fourth quarter of 2020. We evaluated the effects of this error on our previously-issued consolidated financial statements in 
accordance  with  the  guidance  in  Accounting  Standards  Codification  Topic  (ASC)  250,  Accounting  Changes  and  Error 
Corrections,  ASC  250-10-S99-1,  Assessing  Materiality,  and  ASC  250-10-S99-2,  Considering  the  Effects  of  Prior  Year 
Misstatements  when  Quantifying  Misstatements  in  Current  Year  Financial  Statements,  and  concluded  that  no  prior  period  is 
materially misstated. Accordingly, we have revised our consolidated financial statements for the impacted prior periods herein.

Derivatives.  ALLETE  is  exposed  to  certain  risks  relating  to  its  business  operations  that  can  be  managed  through  the  use  of 
derivative instruments. ALLETE may enter into derivative instruments to manage those risks including interest rate risk related 
to certain variable-rate borrowings and commodity price risk related to sales to retail and municipal customers as well as other 
power suppliers. We have determined that either these agreements are not derivatives, or, if they are derivatives, the agreements 
qualify for the normal purchases and normal sales exception to derivative accounting guidance; therefore, derivative accounting 
is not required.

Accounting for Stock-Based Compensation. We apply the fair value recognition guidance for share-based payments. Under 
this  guidance,  we  recognize  stock-based  compensation  expense  for  all  share-based  payments  granted,  net  of  an  estimated 
forfeiture rate. (See Note 13. Employee Stock and Incentive Plans.)

Goodwill. Goodwill is the excess of the purchase price (consideration transferred) over the estimated fair value of net assets of 
acquired businesses. In accordance with GAAP, goodwill is not amortized. Goodwill is assessed annually in the fourth quarter 
for  impairment  and  whenever  an  event  occurs  or  circumstances  change  that  would  indicate  the  carrying  amount  may  be 
impaired. Impairment testing for goodwill is done at the reporting unit level.

As of the date of our annual goodwill impairment testing in 2022, the Company elected to bypass the qualitative assessment of 
goodwill for impairment, proceeding directly to the two-step impairment test for the New Energy reporting unit. In performing 
Step 1 of the impairment test, we compared the fair value of the reporting unit to its carrying value including goodwill. If the 
carrying  value  including  goodwill  were  to  exceed  the  fair  value  of  a  reporting  unit,  Step  2  of  the  impairment  test  would  be 
performed. Step 2 of the impairment test requires the carrying value of goodwill to be reduced to its fair value, if lower, as of 
the test date.

For Step 1 of the impairment test, we estimated the reporting unit's fair value using standard valuation techniques, including 
techniques which use estimates of projected future results and cash flows to be generated by the reporting unit. Such techniques 
generally  include  a  terminal  value  that  utilizes  a  growth  rate  on  debt-free  cash  flows.  These  cash  flow  valuations  involve  a 
number  of  estimates  that  require  broad  assumptions  and  significant  judgment  by  management  regarding  future  performance. 
Our  annual  impairment  test  in  2022  indicated  that  the  estimated  fair  value  of  New  Energy  exceeded  its  carrying  value,  and 
therefore no impairment existed. The fair value of the reporting unit was determined using a discounted cash flow model, using 
significant assumptions which included a discount rate of 14 percent, cash flow forecasts through 2027, industry average gross 
margins, and a terminal growth rate of 3.5 percent.

Leases. We determine if a contract is, or contains, a lease at inception and recognize a right-of-use asset and lease liability for 
all leases with a term greater than 12 months. Our right-of-use assets and lease liabilities for operating leases are included in 
Other  Non-Current  Assets,  Other  Current  Liabilities  and  Other  Non-Current  Liabilities,  respectively,  in  our  Consolidated 
Balance Sheet. We currently do not have any finance leases.

Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent the obligation 
to  make  lease  payments  arising  from  the  lease.  Operating  lease  right-of-use  assets  and  lease  liabilities  are  recognized  at  the 
commencement date based on the estimated present value of lease payments over the lease term. As our leases do not provide 
an  explicit  rate,  we  determine  the  present  value  of  future  lease  payments  based  on  our  estimated  incremental  borrowing  rate 
using information available at the lease commencement date. The operating lease right-of-use asset includes lease payments to 
be made during the lease term and any lease incentives, as applicable. 

Our  leases  may  include  options  to  extend  or  buy  out  the  lease  at  certain  points  throughout  the  term,  and  if  it  is  reasonably 
certain  at  lease  commencement  that  we  will  exercise  that  option,  we  include  those  rental  payments  in  our  calculation  of  the 
right-of-use asset and lease liability. Lease and rent expense is recognized on a straight-line basis over the lease term. Leases 
with a term of 12 months or less are not recognized on the Consolidated Balance Sheet. 

The majority of our operating leases are for heavy equipment, vehicles and land with fixed monthly payments which we group 
into two categories: Vehicles and Equipment; and Land and Other. Our largest operating lease is for the dragline at BNI Energy 
which includes a termination payment at the end of the lease term if we do not exercise our purchase option. The amount of this 
payment is $3 million and is included in our calculation of the right-of-use asset and lease liability recorded. None of our other 
leases contain residual value guarantees.

Environmental  Liabilities.  We  review  environmental  matters  on  a  quarterly  basis.  Accruals  for  environmental  matters  are 
recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based 
on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional 
technical  or  legal  information  becomes  available.  Accruals  for  environmental  liabilities  are  included  in  the  Consolidated 
Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to 
environmental  contamination  treatment  and  cleanup  are  expensed  unless  recoverable  in  rates  from  customers.  (See  Note  9. 
Commitments, Guarantees and Contingencies.)

Revenue.

Contracts with Customers – Utility includes sales from our regulated operations for generation, transmission and distribution of 
electric service, and distribution of water and gas services to our customers. Also included is an immaterial amount of regulated 
steam generation that is used by customers in the production of paper and pulp.

Contracts with Customers – Non-utility includes sales of goods and services to customers from ALLETE Clean Energy and our 
Corporate and Other businesses. 

Other  –  Non-utility  is  the  non-cash  adjustments  to  revenue  recognized  by  ALLETE  Clean  Energy  for  the  amortization  of 
differences between contract prices and estimated market prices for PSAs that were assumed during the acquisition of various 
wind energy facilities.

Revenue Recognition. Revenue is recognized upon transfer of control of promised goods or services to our customers in an 
amount that reflects the consideration we expect to receive in exchange for those products or services. Revenue is recognized 
net  of  allowance  for  returns  and  any  taxes  collected  from  customers,  which  are  subsequently  remitted  to  the  appropriate 
governmental authorities. We account for shipping and handling activities that occur after the customer obtains control of goods 
as  a  cost  rather  than  an  additional  performance  obligation  thereby  recognizing  revenue  at  time  of  shipment  and  accruing 
shipping and handling costs when control transfers to our customers. We have a right to consideration from our customers in an 
amount  that  corresponds  directly  with  the  value  to  the  customer  for  our  performance  completed  to  date;  therefore,  we  may 
recognize revenue in the amount to which we have a right to invoice.

Nature of Revenue Streams 

Utility

Residential and Commercial includes sales for electric, gas or water service to customers, who have implied contracts with the 
utility,  under  rates  governed  by  the  MPUC,  PSCW  or  FERC.  Customers  are  billed  on  a  monthly  cycle  basis  and  revenue  is 
recognized for electric, gas or water service delivered during the billing period. Revenue is accrued for service provided but not 
yet billed at period end. Performance obligations with these customers are satisfied at time of delivery to customer meters and 
simultaneously consumed.

Municipal includes sales to 14 non-affiliated municipal customers in Minnesota under long-term wholesale electric contracts. 
One of these wholesale electric contracts include a termination clause requiring a three-year notice to terminate. These contracts 
have termination dates ranging through 2037, with a majority of contracts expiring in 2029. Performance obligations with these 
customers are satisfied at the time energy is delivered to an agreed upon municipal substation or meter. 

Industrial  includes  sales  recognized  from  contracts  with  customers  in  the  taconite  mining,  paper,  pulp  and  secondary  wood 
products, pipeline and other industries. Industrial sales accounted for approximately 52 percent of total regulated utility kWh 
sales  for  the  year  ended  December  31,  2022.  Within  industrial  revenue,  Minnesota  Power  had  seven  Large  Power  Customer 
contracts,  each  serving  requirements  of  10  MW  or  more  of  customer  load  as  of  December  31,  2022.  These  contracts 
automatically  renew  past  the  contract  term  unless  a  four-year  written  notice  is  given.  Large  Power  Customer  contracts  have 
earliest termination dates ranging from 2026 through 2029. We satisfy our performance obligations for these customers at the 
time energy is delivered to an agreed upon customer substation. Revenue is accrued for energy provided but not yet billed at 
period  end.  Based  on  current  contracts  with  industrial  customers,  we  expect  to  recognize  minimum  revenue  for  the  fixed 
contract  components  of  approximately  $55  million  per  annum  through  2026,  $15  million  in  2027,  and  $25  million  in  total 
thereafter, which reflects the termination notice period in these contracts. When determining minimum revenue, we assume that 
customer  contracts  will  continue  under  the  contract  renewal  provision;  however,  if  long-term  contracts  are  renegotiated  and 
subsequently approved by the MPUC or there are changes within our industrial customer class, these amounts may be impacted. 
Contracts  with  customers  that  contain  variable  pricing  or  quantity  components  are  excluded  from  the  expected  minimum 
revenue amounts.  

Other  Power  Suppliers  includes  the  sale  of  energy  under  a  long-term  PSA  with  one  customer  as  well  as  MISO  market  and 
liquidation sales. The expiration date of this PSA is 2028. Performance obligations with these customers are satisfied at the time 
energy  is  delivered  to  an  agreed  upon  delivery  point  defined  in  the  contract  (generally  the  MISO  pricing  node).  The  current 
contract with one customer contains variable pricing components that prevent us from estimating future minimum revenue.

Other  Revenue  includes  all  remaining  individually  immaterial  revenue  streams  for  Minnesota  Power  and  SWL&P,  and  is 
comprised of steam sales to paper and pulp mills, wheeling revenue and other sources. Revenue for steam sales to customers is 
recognized at the time steam is delivered and simultaneously consumed. Revenue is recognized at the time each performance 
obligation is satisfied. 

CIP Financial Incentive reflects certain revenue that is a result of the achievement of certain objectives for our CIP financial 
incentives. This revenue is accounted for in accordance with the accounting standards for alternative revenue programs which 
allow for the recognition of revenue under an alternative revenue program if the program is established by an order from the 
utility’s regulatory commission, the order allows for automatic adjustment of future rates, the amount of revenue recognized is 
objectively determinable and probable of recovery, and the revenue will be collected within 24 months following the end of the 
annual period in which it is recognized. CIP financial incentives are recognized in the period in which the MPUC approves the 
filing, which is typically mid-year.

ALLETE Clean Energy

Long-term  PSA  revenue  includes  all  sales  recognized  under  long-term  contracts  for  production,  curtailment,  capacity  and 
associated renewable energy credits from ALLETE Clean Energy wind energy facilities. Expiration dates of these PSAs range 
from 2024 through 2039. Performance obligations for these contracts are satisfied at the time energy is delivered to an agreed 
upon point, or production is curtailed at the request of the customer, at specified prices. Revenue from the sale of renewable 
energy credits is recognized at the same time the related energy is delivered to the customer when sold to the same party. 

Sale of Wind Energy Facility includes revenue recognized for the design, development, construction, and sale of a wind energy 
facility to a customer. Performance obligations for these types of agreements are satisfied at the time the completed project is 
transferred to the customer at the commercial operation date. Revenue from the sale of a wind energy facility is recognized at 
the time of asset transfer. 

Other is the non-cash adjustments to revenue recognized by ALLETE Clean Energy for the amortization of differences between 
contract  prices  and  estimated  market  prices  on  assumed  PSAs.  As  part  of  wind  energy  facility  acquisitions,  ALLETE  Clean 
Energy  assumed  various  PSAs  that  were  above  or  below  estimated  market  prices  at  the  time  of  acquisition;  the  resulting 
differences between contract prices and estimated market prices are amortized to revenue over the remaining PSA term.

Corporate and Other 

Long-term  Contract  encompasses  the  sale  and  delivery  of  coal  to  customer  generation  facilities.  Revenue  is  recognized  on  a 
monthly basis at the cost of production plus a specified profit per ton of coal delivered to the customer. Coal sales are secured 
under  long-term  coal  supply  agreements  extending  through  2037.  Performance  obligations  are  satisfied  during  the  period  as 
coal is delivered to customer generation facilities. 

Sale  of  Renewable  Development  Projects  includes  revenue  recognized  from  development  only  and  development  plus 
construction  type  projects  that  are  sold  to  a  customer.  For  development  only  projects,  revenue  is  recognized  at  point  in  time 
when  all  required  development  responsibilities  have  been  completed  and  ownership  has  transferred  to  the  customer.  For 
development  plus  construction,  the  transaction  price  is  allocated  to  two  performance  obligations  based  upon  the  standalone 
selling price of each obligation. Revenue is recognized on the development performance obligation upon satisfying all required 
development  activities  and  ownership  transferring  to  the  customer.  Revenue  for  the  construction  performance  obligation  is 
recognized  over  time  based  on  construction  costs  incurred,  beginning  at  notice  to  proceed  through  the  commercial  operation 
date.

Other primarily includes revenue from BNI Energy unrelated to coal, revenue from New Energy for asset management services 
and non-development activities, the sale of real estate from ALLETE Properties, and non-rate base steam generation that is sold 
for use during production of paper and pulp. Performance obligations are satisfied when control transfers to the customer.

Payment  Terms.  Payment  terms  and  conditions  vary  across  our  businesses.  Aside  from  taconite-producing  Large  Power 
Customers,  payment  terms  generally  require  payment  to  be  made  within  15  to  30  days  from  the  end  of  the  period  that  the 
service has been rendered. In the case of its taconite-producing Large Power Customers, as permitted by the MPUC, Minnesota 
Power  requires  weekly  payments  for  electric  usage  based  on  monthly  energy  usage  estimates.  These  customers  receive 
estimated  bills  based  on  Minnesota  Power’s  estimate  of  the  customers’  energy  usage,  forecasted  energy  prices  and  fuel 
adjustment clause estimates. Minnesota Power’s taconite-producing Large Power Customers have generally predictable energy 
usage  on  a  weekly  basis  and  any  differences  that  occur  are  trued-up  the  following  month.  Due  to  the  timing  difference  of 
revenue recognition from the timing of invoicing and payment, the taconite-producing Large Power Customers receive credit 
for the time value of money; however, we have determined that our contracts do not include a significant financing component 
as the period between when we transfer the service to the customer and when they pay for such service is minimal.

Assets Recognized From the Costs to Obtain a Contract with a Customer. We recognize as an asset the incremental costs 
of  obtaining  a  contract  with  a  customer  if  we  expect  the  benefit  of  those  costs  to  be  longer  than  one  year.  We  expense 
incremental costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year 
or less. As of December 31, 2022, we have $21.0 million of assets recognized for costs incurred to obtain contracts with our 
customers ($23.3 million as of December 31, 2021). Management determined the amount of costs to be recognized as assets 
based  on  actual  costs  incurred  and  paid  to  obtain  and  fulfill  these  contracts  to  provide  goods  and  services  to  our  customers. 
Assets recognized to obtain contracts are amortized on a straight-line basis over the contract term as a non-cash reduction to 
revenue. We recognized $2.4 million of non-cash amortization for the year ended December 31, 2022 ($2.7 million for the year 
end December 31, 2021).

Unamortized Discount and Premium on Debt. Discount and premium on debt are deferred and amortized over the terms of 
the related debt instruments using a method which approximates the effective interest method.

Tax Equity Financings. Certain subsidiaries of ALLETE have entered into tax equity financings that include forming limited 
liability companies (LLC) with third-party investors for certain wind projects. Tax equity financings have specific terms that 
dictate distributions of cash and the allocation of tax attributes among the LLC members, who are divided into two categories: 
the sponsor and third-party investors. ALLETE subsidiaries are the sponsors in these tax equity financings. The distributions of 
cash and allocation of tax attributes in these financings generally differ from the underlying ownership percentage interests in 
the related LLC, with a disproportionate share of tax attributes (including accelerated depreciation and production tax credits) 
allocated to third-party investors in order to achieve targeted after-tax rates of return, or target yield, from project operations, 
and a disproportionate share of cash distributions made to the sponsor. 

The  target  yield  and  other  terms  vary  by  tax  equity  financing.  Once  the  target  yield  has  been  achieved,  a  “flip  point”  is 
recognized. In addition, tax equity financings typically provide that cash distributions can be temporarily increased to the third-
party investors in order to meet cumulative distribution thresholds. After the flip point, tax attributes and cash distributions are 
both typically disproportionately allocated to the sponsor.

Tax equity financings include affirmative and negative covenants that are similar to what a project lender would require in a 
project financing, such as financial reporting, insurance, maintenance and prudent operator standards. Most covenants are no 
longer applicable once the flip point occurs and any other obligations of the third-party investor have been eliminated.

The  third-party  investors’  portions  of  equity  ownership  in  tax  equity  LLCs  are  recorded  as  non-controlling  interest  in 
subsidiaries  on  the  Consolidated  Balance  Sheet  and  earnings  allocated  to  third-party  investors  are  recorded  as  net  loss 
attributable to non-controlling interest on the Consolidated Statement of Income.

Non-Controlling Interest in Subsidiaries. Non-controlling interest in subsidiaries represents the portion of equity ownership, 
net income (loss), and comprehensive income (loss) in subsidiaries that is not attributable to equity holders of ALLETE. These 
amounts as of and for the years ended December 31, 2022 and 2021, related to the tax equity financings for ALLETE Clean 
Energy’s 106 MW Glen Ullin, 80 MW South Peak, 303 MW Diamond Spring and 303 MW Caddo wind energy facilities as 
well as ALLETE’s equity investment in the 250 MW Nobles 2 wind energy facility.

For  those  wind  projects  with  tax  equity  financings  where  the  economic  benefits  are  not  allocated  based  on  the  underlying 
ownership  percentage  interests,  we  have  determined  that  the  appropriate  methodology  for  calculating  the  non-controlling 
interest in subsidiaries balance is the hypothetical liquidation at book value (HLBV) method. The HLBV method is a balance 
sheet approach which reflects the substantive economic arrangements in the tax equity financing structures. 

Under  the  HLBV  method,  amounts  reported  as  non-controlling  interest  in  subsidiaries  on  the  Consolidated  Balance  Sheet 
represent  the  amounts  the  third-party  investors  would  hypothetically  receive  at  each  balance  sheet  reporting  date  under  the 
liquidation  provisions  of  the  LLC  agreements,  assuming  the  net  assets  of  the  wind  projects  were  liquidated  at  amounts 
determined  in  accordance  with  GAAP  and  distributed  to  the  third-party  investor  and  sponsor.  The  resulting  non-controlling 
interest in subsidiaries balance in these projects is reported as a component of equity on the Consolidated Balance Sheet. 

The results of operations for these projects attributable to non-controlling interest under the HLBV method is determined as the 
difference in non-controlling interest in subsidiaries on the Consolidated Balance Sheet at the start and end of each reporting 
period, after taking into account any capital transactions between the projects and the third-party investors. 

ALLETE, Inc. 2022 Form 10-K

NOTE 1.  OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

Factors  used  in  the  HLBV  calculation  include  GAAP  income,  taxable  income  (loss),  tax  attributes  such  as  accelerated 
depreciation  and  production  tax  credits,  capital  contributions,  cash  distributions,  and  the  target  yield  specified  in  the 
corresponding  LLC  agreement.  Changes  in  these  factors  could  have  a  significant  impact  on  the  amounts  that  third-party 
investors and sponsors would receive upon a hypothetical liquidation. The use of the HLBV method to allocate income to the 
non-controlling  interest  in  subsidiaries  may  create  variability  in  our  results  of  operations  as  the  application  of  the  HLBV 
method can drive variability in net income or loss attributable to non-controlling interest in subsidiaries from period to period.

Non-Utility on the Consolidated Statement of Income.

Income  Taxes.  ALLETE  and  its  subsidiaries  file  a  consolidated  federal  income  tax  return  as  well  as  combined  and  separate 
state income tax returns. We account for income taxes using the liability method in accordance with GAAP for income taxes. 
Under the liability method, deferred income tax assets and liabilities are established for all temporary differences in the book 
and tax basis of assets and liabilities, based upon enacted tax laws and rates applicable to the periods in which the taxes become 
payable. 

Due to the effects of regulation on Minnesota Power and SWL&P, certain adjustments made to deferred income taxes are, in 
turn, recorded as regulatory assets or liabilities. 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 credits related to public utility property. In accordance with GAAP for uncertainty in income taxes, we 
are required to recognize in our financial statements the largest tax benefit of a tax position that is “more-likely-than-not” to be 
sustained on audit, based solely on the technical merits of the position as of the reporting date. The term “more-likely-than-not” 
means more than 50 percent likely. (See Note 11. Income Tax Expense.)

Excise Taxes. We collect excise taxes from our customers levied by governmental entities. These taxes are stated separately on 
the billing to the customer and recorded as a liability to be remitted to the governmental entity. We account for the collection 
and payment of these taxes on a net basis.

Asset  Retirement  Obligations.  We  recognize,  at  fair  value,  obligations  associated  with  the  retirement  of  certain  tangible, 
long-lived assets that result from the acquisition, construction, development or normal operation of the asset. Asset retirement 
obligations (AROs) relate primarily to the decommissioning of our coal-fired and wind energy facilities, and land reclamation 
at  BNI  Energy.  AROs  are  included  in  Other  Non-Current  Liabilities  on  the  Consolidated  Balance  Sheet.  The  associated 
retirement costs are capitalized as part of the related long-lived asset and depreciated over the useful life of the asset. Removal 
costs  associated  with  certain  distribution  and  transmission  assets  have  not  been  recognized,  as  these  facilities  have 
indeterminate useful lives. 

Conditional  asset  retirement  obligations  have  been  identified  for  treated  wood  poles  and  remaining  polychlorinated  biphenyl 
and  asbestos-containing  assets;  however,  the  period  of  remediation  is  indeterminable  and  removal  liabilities  have  not  been 
recognized.

Long-standing ratemaking practices approved by applicable state and federal regulatory authorities have allowed provisions for 
future  plant  removal  costs  in  depreciation  rates.  These  plant  removal  cost  recoveries  are  classified  either  as  AROs  or  as  a 
regulatory liability for non-AROs. To the extent annual accruals for plant removal costs differ from accruals under approved 
depreciation  rates,  a  regulatory  asset  has  been  established  in  accordance  with  GAAP  for  AROs.  (See  Note  4.  Regulatory 
Matters.)

NOTE 4.  REGULATORY MATTERS

Electric  Rates.  Entities  within  our  Regulated  Operations  segment  file  for  periodic  rate  revisions  with  the  MPUC,  PSCW  or 
FERC.  As  authorized  by  the  MPUC,  Minnesota  Power  also  recognizes  revenue  under  cost  recovery  riders  for  transmission, 
renewable and environmental investments and expenditures. (See Transmission Cost Recovery Rider, Renewable Cost Recovery 
Rider,  Solar  Cost  Recovery  Rider  and  Environmental  Improvement  Rider.)  Revenue  from  cost  recovery  riders  was 
$38.8 million in 2022 ($38.9 million in 2021; $29.9 million in 2020). 

Minnesota Retail Rates. Minnesota Power’s retail rates through 2021 were based on a 2018 MPUC retail rate order that allowed 
for a 9.25 percent return on common equity and a 53.81 percent equity ratio. The resolution of Minnesota Power’s 2020 general 
rate case did not change the allowed return on equity or equity ratio. (See 2020 Minnesota General Rate Case.)

2020 Minnesota General Rate Case. In November 2019, Minnesota Power filed a retail rate increase request with the MPUC 
seeking an average increase of approximately 10.6 percent for retail customers. In December 2019 orders, the MPUC accepted 
the filing as complete and authorized an annual interim rate increase of $36.1 million beginning January 1, 2020.

In April 2020, Minnesota Power filed a request with the MPUC that proposed a resolution of Minnesota Power’s 2020 general 
rate case. Key components of our proposal included removing the power marketing margin credit in base rates and reflecting 
actual  power  marketing  margins  in  the  fuel  adjustment  clause  effective  May  1,  2020;  refunding  to  customers  interim  rates 
collected through April 2020; increasing customer rates 4.1 percent compared to the 5.8 percent increase reflected in interim 
rates;  and  a  provision  that  Minnesota  Power  would  not  file  another  rate  case  until  at  least  November  1,  2021,  unless  certain 
events occur. In a June 2020 order, the MPUC approved Minnesota Power’s petition and proposal to resolve and withdraw the 
general rate case. Effective May 1, 2020, customer rates were set at an increase of 4.1 percent with the removal of the power 
marketing  margin  credit  from  base  rates.  Actual  power  marketing  margins  are  now  reflected  in  the  fuel  adjustment  clause. 
Reserves for interim rates of $11.7 million were recorded in the second quarter of 2020 and refunded in the third and fourth 
quarters of 2020.

2022  Minnesota  General  Rate  Case.  On  November  1,  2021,  Minnesota  Power  filed  a  retail  rate  increase  request  with  the 
MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 
10.25  percent  and  a  53.81  percent  equity  ratio.  On  an  annualized  basis,  the  requested  final  rate  increase  would  generate 
approximately  $108  million  in  additional  revenue.  In  orders  dated  December  30,  2021,  the  MPUC  accepted  the  filing  as 
complete and authorized an annual interim rate increase beginning January 1, 2022, with approximately $80 million expected to 
be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination 
on recovery at the end of the rate case.

At a hearing on January 23, 2023, the MPUC made determinations regarding Minnesota Power’s general rate case including 
allowing a return on common equity of 9.65 percent and a 52.50 percent equity ratio. Upon commencement of final rates, we 
expect additional revenue from base rates of approximately $60 million and an additional $10 million in revenue recognized 
under cost recovery riders on an annualized basis, subject to final written order and reconsideration. Final rates are expected to 
commence in the third quarter of 2023; interim rates will be collected through this period with reserves recorded as necessary. 
As a result of the MPUC’s determinations made on January 23, 2023, Minnesota Power has recorded a reserve for an interim 
rate refund of approximately $18 million pre-tax as of December 31, 2022, which is subject to MPUC approval of Minnesota 
Power’s refund calculation. In addition, Minnesota Power recorded a charge of approximately $8 million pre-tax to write-off 
the deferred portion of residential customer interim rates. Minnesota Power also recorded additional revenue of approximately 
$9 million pre-tax for an increase in expected recoveries under its cost recovery riders. Impacts of regulatory outcomes that are 
determined  subsequent  to  the  balance  sheet  date,  and  prior  to  issuance  of  the  financial  statements,  are  recognized  in  the 
financial statements as of the balance sheet date.  

FERC-Approved  Wholesale  Rates.  Minnesota  Power  has  wholesale  contracts  with  14  non-affiliated  municipal  customers  in 
Minnesota and SWL&P. Two of the wholesale contracts include a termination clause requiring a three-year notice to terminate.  

Minnesota  Power’s  wholesale  electric  contract  with  the  Nashwauk  Public  Utilities  Commission  is  effective  through 
December 31, 2037. The wholesale electric service contract with SWL&P is effective through February 28, 2026. Under the 
agreement with SWL&P, no termination notice has been given. The rates included in these two contracts are set each July 1 
based  on  a  cost-based  formula  methodology,  using  estimated  costs  and  a  rate  of  return  that  is  equal  to  Minnesota  Power’s 
authorized rate of return for Minnesota retail customers. The formula-based rate methodology also provides for a yearly true-up 
calculation for actual costs incurred.

NOTE 4.  REGULATORY MATTERS (Continued)
Electric Rates (Continued)

Minnesota  Power’s  wholesale  electric  contracts  with  13  other  municipal  customers  were  extended  in  January  2022  and  are 
effective through 2029. These contracts are based on fixed prices for capacity and energy. The base energy charge for each year 
is adjusted annually for updated fuel and purchased power costs.

Transmission Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place to charge retail customers on 
a  current  basis  for  certain  transmission  investments  and  expenditures,  including  a  return  on  the  capital  invested.  Current 
customer  billing  rates  are  based  on  an  MPUC  order  dated  December  27,  2022,  which  provisionally  approved  Minnesota 
Power’s latest transmission factor filing submitted on October 31, 2022.  

Renewable Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place to charge retail customers on a 
current basis for the costs of certain renewable investments and expenditures, including a return on the capital invested. Current 
customer billing rates for the renewable cost recovery rider were approved by the MPUC in a 2020 order. On February 2, 2022, 
Minnesota  Power  submitted  its  latest  renewable  factor  filing,  which  included  a  request  to  recover  a  regulatory  asset  of 
$3.8 million related to the recognition of production tax credits due to a metering error at Bison. The filing was approved in an 
order dated January 24, 2023 authorizing Minnesota Power to include updated billing rates on customer bills for recovery of the 
regulatory asset.

Solar  Cost  Recovery  Rider.  Minnesota  Power  has  an  approved  cost  recovery  rider  in  place  to  charge  retail  customers  on  a 
current basis for solar costs related to investments and expenditures for meeting the state of Minnesota’s solar energy standard. 
Current customer billing rates for the solar cost recovery rider were approved by the MPUC in an order dated August 31, 2022.

Electric Vehicle Charging Infrastructure Petition. In April 2021, Minnesota Power filed a petition seeking approval to install 
and  own  DC  fast  charger  stations  for  electric  vehicles  across  its  service  territory,  implement  accompanying  rates  for  those 
stations,  and  track  and  recover  investments  and  expenses  for  the  project.  In  an  October  2021  order,  the  MPUC  approved 
Minnesota Power’s petition.

Fuel  Adjustment  Clause.  In  2020,  Minnesota  Power  filed  its  fuel  adjustment  forecast  for  2021,  which  was  approved  by  the 
MPUC in a December 2020 order, subject to the annual prudence review and true-up filing in 2022. During 2021, Minnesota 
Power  incurred  higher  fuel  and  purchased  power  costs  than  those  forecasted  in  its  May  2020  filing,  which  resulted  in  the 
recognition  of  an  approximately  $56  million  regulatory  asset  through  December  31,  2021.  Minnesota  Power  submitted  its 
annual true-up filing and a significant events filing in March 2022 requesting recovery of these under-collected fuel adjustment 
clause  recoveries.  The  MPUC  approved  recovery  of  the  regulatory  asset  in  an  order  dated  July  5,  2022;  recovery  of  the 
regulatory asset will continue through mid-2023. 

Minnesota Power also incurred higher fuel and purchased power costs in 2022 than those factored in its fuel adjustment forecast 
filed  in  May  2021  for  2022,  which  resulted  in  the  recognition  of  an  approximately  $13  million  regulatory  asset  as  of 
December  31,  2022.  Minnesota  Power  filed  a  significant  events  filing  in  June  2022  requesting  to  increase  rates  from 
August  2022  through  December  2022  in  order  to  recover  the  under-collected  fuel  adjustment  clause  recoveries  that  were 
expected for 2022. No parties objected to the request and higher rates were implemented in August 2022. Minnesota Power will 
request recovery of the remaining regulatory asset as part of its annual true-up filing expected to be submitted to the MPUC in 
March 2023.

In  2020,  Minnesota  Power  filed  its  FAC  report  covering  the  period  July  2018  through  December  2019.  In  a  2020  order,  the 
MPUC  referred  the  review  of  Minnesota  Power’s  forced  outage  costs  during  the  period  of  the  report,  which  totaled 
approximately $8 million, to an administrative law judge (ALJ) for a contested case hearing to recommend to the MPUC if any 
of  those  costs  should  be  returned  to  customers.  On  August  11,  2021,  the  ALJ  recommended  that  Minnesota  Power  refund 
approximately $5 million to ratepayers. Minnesota Power submitted exceptions to the ALJ’s report to the MPUC stating that it 
disagreed  with  the  ALJ’s  recommendation  and  that  no  refund  should  be  made  as  the  Company  operated  its  facilities  in 
accordance with good utility practice. At a hearing on January 13, 2022, the MPUC agreed with the ALJ’s recommendation and 
ordered the refund of approximately $5 million to ratepayers, which was recorded as a reserve as of December 31, 2021, and 
refunded to customers in 2022.

Wisconsin Retail Rates. SWL&P’s retail rates through 2022 were based on a December 2018 order by the PSCW that allowed 
for a return on equity of 10.4 percent and a 55.0 percent equity ratio.

NOTE 4.  REGULATORY MATTERS (Continued)
Electric Rates (Continued)

2022 Wisconsin General Rate Case. In 2022, SWL&P filed a rate increase request with the PSCW seeking an average increase 
of 3.6 percent for retail customers. The filing sought an overall return on equity of 10.4 percent and a 55 percent equity ratio. 
On an annualized basis, the requested final rate increase would have generated an estimated $4.3 million in additional revenue. 
In an order dated December 20, 2022, the PSCW approved an annual increase of $3.3 million reflecting a return on equity of 
10.0 percent and 55 percent equity ratio. Final rates went into effect January 1, 2023.

Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP, which was approved by the MPUC in 
an order dated January 9, 2023. The approved IRP, which reflects a joint agreement reached with various stakeholders, outlines 
Minnesota  Power’s  clean-energy  transition  plans  through  2035.  These  plans  include  expanding  its  renewable  energy  supply, 
achieving  coal-free  operations  at  its  facilities  by  2035,  and  investing  in  a  resilient  and  flexible  transmission  and  distribution 
grid. As part of these plans, Minnesota Power anticipates adding up to 700 MW of new wind and solar energy resources, and 
ceasing  coal  operations  at  Boswell  Units  3  and  4  by  2030  and  2035,  respectively.  Minnesota  Power’s  plans  recognize  that 
advances  in  technology  will  play  a  significant  role  in  completing  its  transition  to  carbon-free  energy  supply,  reliably  and 
affordably. Minnesota Power is expected to file its next IRP by March 1, 2025.

Conservation  Improvement  Program.  Minnesota  requires  electric  utilities  to  spend  a  minimum  of  1.5  percent  of  gross 
operating revenues, excluding revenue received from exempt customers, from service provided in the state on energy CIPs each 
year. 

On April 1, 2022, Minnesota Power submitted its 2021 consolidated filing detailing Minnesota Power’s CIP program results 
and proposed CIP financial incentive, which was approved by the MPUC in an order dated July 5, 2022. As a result, Minnesota 
Power  recognized  revenue  of  $1.9  million  in  2022  for  the  approved  CIP  financial  incentive  ($2.4  million  in  2021  and  
$2.4 million in 2020). CIP financial incentives are recognized in the period in which the MPUC approves the filing.

In 2020, Minnesota Power submitted its CIP triennial filing for 2021 through 2023 to the MPUC and Minnesota Department of 
Commerce, which outlines Minnesota Power’s CIP spending and energy-saving goals for those years. Minnesota Power’s CIP 
investment goal is $10.9 million for 2023.

MISO Return on Equity Complaint. MISO transmission owners, including ALLETE and ATC, have an authorized return on 
equity of 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional transmission organization 
based on a 2020 FERC order which is subject to various outstanding legal challenges related to the return on equity calculation 
and refund period ordered by the FERC. On August 9, 2022, the U.S. Court of Appeals for the District of Columbia Circuit 
vacated  and  remanded  the  2020  FERC  order  back  to  the  FERC.  We  cannot  predict  the  return  on  equity  the  FERC  will 
ultimately authorize in the remanded proceeding. (See Note 6. Equity Investments.)

Minnesota Solar Energy Standard. Minnesota law requires at least 1.5 percent of total retail electric sales, excluding sales to 
certain customers, to be generated by solar energy. At least 10 percent of the 1.5 percent mandate must be met by solar energy 
generated  by  or  procured  from  solar  photovoltaic  devices  with  a  nameplate  capacity  of  40  kW  or  less  and  community  solar 
garden subscriptions. Minnesota Power has met both parts of the solar mandate to date. 

In  June  2020,  Minnesota  Power  filed  proposal  with  the  MPUC  to  accelerate  its  plans  for  purchasing  solar  energy  from 
approximately  20  MW  of  solar  energy  projects  in  Minnesota  which  was  approved  in  a  June  2021  order.  These  solar  energy 
projects  will  be  constructed  and  owned  through  an  ALLETE  subsidiary  with  an  estimated  investment  of  $40  million. 
Construction of these solar energy projects commenced in 2022 with a portion of these projects placed into service in the fourth 
quarter of 2022; the remaining project is expected to be placed into service in 2023.

Regulatory Assets and Liabilities. Our regulated utility operations are subject to accounting standards for the effects of certain 
types  of  regulation.  Regulatory  assets  represent  incurred  costs  that  have  been  deferred  as  they  are  probable  for  recovery  in 
customer  rates.  Regulatory  liabilities  represent  obligations  to  make  refunds  to  customers  and  amounts  collected  in  rates  for 
which the related costs have not yet been incurred. The Company assesses quarterly whether regulatory assets and liabilities 
meet the criteria for probability of future recovery or deferral. With the exception of the regulatory asset for Boswell Units 1 
and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates 
for these regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or 
over the corresponding period related to the asset or liability.

(a) Current regulatory assets are presented within Prepayments and Other on the Consolidated Balance Sheet.
(b) Fuel adjustment clause regulatory asset and liability represent the amount expected to be recovered from or refunded to customers for 

the under- or over-collection of fuel adjustment clause recoveries. (See Fuel Adjustment Clause.)

(c) Defined  benefit  pension  and  other  postretirement  items  included  in  our  Regulated  Operations,  which  are  otherwise  required  to  be 
recognized  in  accumulated  other  comprehensive  income,  are  recognized  as  regulatory  assets  or  regulatory  liabilities  on  the 
Consolidated Balance Sheet. The asset or liability will decrease as the deferred items are amortized and recognized as components of 
net periodic benefit cost. (See Note 12. Pension and Other Postretirement Benefit Plans.) 

(d) These costs represent the difference between deferred income taxes recognized for financial reporting purposes and amounts previously 

billed to our customers. The balances will primarily decrease over the remaining life of the related temporary differences.

(e) The cost recovery rider regulatory assets and liabilities are revenue not yet collected from our customers and cash collections from our 
customers in excess of the revenue recognized, respectively, primarily due to capital expenditures related to Bison and the GNTL as well 
as differences between production tax credits recognized and those assumed in Minnesota Power’s base rates. The cost recovery rider 
regulatory assets as of December 31, 2022, will be recovered within the next two years.

(f) Asset retirement obligations will accrete and be amortized over the lives of the related property with asset retirement obligations.
(g) This  regulatory  asset  represents  costs  of  remediation  for  a  former  manufactured  gas  plant  site  located  in  Superior,  Wisconsin,  and 

formerly operated by SWL&P. We expect recovery of these remediation costs to be allowed by the PSCW in rates over time.

NOTE 5. ACQUISITIONS

2022 Activity

New Energy. On April 15, 2022, a wholly-owned subsidiary of ALLETE acquired 100 percent of the membership interests of 
New Energy for a purchase price of $165.5 million. Total consideration of approximately $158.8 million was paid in cash on 
the  acquisition  date,  which  is  net  of  cash  acquired  and  debt  assumed.  New  Energy,  which  is  headquartered  in  Annapolis, 
Maryland, is a renewable energy development company with a primary focus on solar and storage facilities while also offering 
comprehensive  operations,  maintenance  and  asset  management  services.  The  acquisition  of  New  Energy  is  consistent  with 
ALLETE’s  stated  strategy  of  additional  investment  in  renewable  energy  and  related  infrastructure  across  North  America  to 
support the Company’s sustainability-in-action strategy while providing potential long-term earnings growth. 

The acquisition was accounted for as a business combination and the purchase price was allocated based on the estimated fair 
values of the assets acquired and the liabilities assumed at the date of acquisition. The allocation of the purchase price, which 
was  finalized  in  the  fourth  quarter  of  2022,  is  shown  in  the  following  table.  Fair  value  measurements  were  valued  primarily 
using the discounted cash flow method and replacement cost basis. The goodwill recorded is primarily attributable to the highly 
skilled workforce of New Energy and synergies expected to arise as a result of the acquisition. 

Since the acquisition in April 2022, aggregate revenue was $80.2 million. The Company has not presented separate results of 
operations since closing or combined pro forma financial information of the Company and New Energy since the beginning of 
2021, as the results of operations for New Energy are not material to the Company's consolidated financials.

ATC’s authorized return on equity is 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional 
transmission organization, based on a 2020 FERC order which is subject to various outstanding legal challenges related to the 
return  on  equity  calculation  and  refund  period  ordered  by  the  FERC.  On  August  9,  2022,  the  U.S.  Court  of  Appeals  for  the 
District  of  Columbia  Circuit  vacated  and  remanded  the  2020  FERC  order  back  to  FERC.  As  a  result  of  this  decision,  ATC 
recorded a reserve in the third quarter of 2022 for anticipated refunds to its customers for approximately $31 million of which 
our share was approximately $2.4 million pre-tax. We cannot predict the return on equity FERC will ultimately authorize in the 
remanded proceeding.

In addition, the FERC issued a Notice of Proposed Rulemaking in April 2021 proposing to limit the 50 basis point incentive 
adder  for  participation  in  a  regional  transmission  organization  to  only  the  first  three  years  of  membership  in  such  an 
organization. If this proposal is adopted, our equity in earnings from ATC would be reduced by approximately $1 million pre-
tax annually.

NOTE 7.  FAIR VALUE

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between 
market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would 
use  in  pricing  the  asset  or  liability,  including  assumptions  about  risk  and  the  risks  inherent  in  the  inputs  to  the  valuation 
technique.  These  inputs  can  be  readily  observable,  market  corroborated,  or  generally  unobservable.  We  primarily  apply  the 
market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we 
utilize  valuation  techniques  that  maximize  the  use  of  observable  inputs  and  minimize  the  use  of  unobservable  inputs.  These 
inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest 
priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest 
priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows:

Level 1 — Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Active markets 
are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information 
on an ongoing basis. This category includes primarily equity securities.

Level 2 — Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the 
reported date. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities 
or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models 
using  highly  observable  inputs,  such  as  commodity  options  priced  using  observable  forward  prices  and  volatilities.  This 
category includes deferred compensation and fixed income securities.

Level  3  —  Significant  inputs  that  are  generally  less  observable  from  objective  sources.  The  types  of  assets  and  liabilities 
included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and 
subjective models and forecasts used to determine the fair value.

NOTE 7.  FAIR VALUE (Continued)

The following tables set forth by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair 
value on a recurring basis as of December 31, 2022, and December 31, 2021. Each asset and liability is classified based on the 
lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to 
the fair value measurement requires judgment, which may affect the valuation of these assets and liabilities and their placement 
within the fair value hierarchy levels. The estimated fair value of Cash and Cash Equivalents listed on the Consolidated Balance 
Sheet  approximates  the  carrying  amount  and  therefore  is  excluded  from  the  recurring  fair  value  measures  in  the  following 
tables.

Assets  and  Liabilities  Measured  at  Fair  Value  on  a  Nonrecurring  Basis.  Non-financial  assets  such  as  equity  method 
investments, goodwill, intangible assets, and property, plant and equipment are measured at fair value when there is an indicator 
of impairment and recorded at fair value only when an impairment is recognized.

Equity  Method  Investments.  The  aggregate  carrying  amount  of  our  equity  investments  was  $322.7  million  as  of 
December  31,  2022  ($318.0  million  as  of  December  31,  2021).  The  Company  assesses  our  equity  investments  in  ATC  and 
Nobles  2  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  our  investments 
may not be recoverable. For the years ended December 31, 2022 and 2021, there were no indicators of impairment. (See Note 6. 
Equity Investments.)

Goodwill. The Company assesses the impairment of goodwill annually in the fourth quarter and whenever an event occurs or 
circumstances change that would indicate that the carrying amount may be impaired. The Company’s goodwill is a result of the 
New Energy acquisition in 2022. (See Note 1. Operations and Significant Accounting Policies and Note 5. Acquisitions.) The 
aggregate carrying amount of goodwill was $154.9 million as of December 31, 2022.

Property, Plant and Equipment. The Company assesses the impairment of property, plant, and equipment whenever events or 
changes in circumstances indicate that the carrying amount of property, plant, and equipment assets may not be recoverable. 
(See Note 1. Operations and Significant Accounting Policies.) For the years ended December 31, 2022, and 2021, there was no 
impairment of property, plant, and equipment. 

We believe that long-standing ratemaking practices approved by applicable state and federal regulatory commissions allow for 
the recovery of the remaining book value of retired plant assets. The MPUC order for Minnesota Power’s 2015 IRP directed 
Minnesota Power to retire Boswell Units 1 and 2, which occurred in the fourth quarter of 2018. As part of the 2016 general 
retail rate case, the MPUC allowed recovery of the remaining book value of Boswell Units 1 and 2 through 2022. Minnesota 
Power’s latest IRP, which was approved by the MPUC in an order dated January 9, 2023, includes ceasing coal operations at 
Boswell  Units  3  and  4  by  2030  and  2035,  respectively.  Boswell  Unit  3  and  Unit  4  have  a  net  book  value  of  approximately 
$235 million and $435 million, respectively, as of December 31, 2022. (See Note 4. Regulatory Matters.) Minnesota Power’s 
latest IRP also includes the retirement of Taconite Harbor. As of December 31, 2022, Taconite Harbor had a net book value of 
approximately $25 million. We do not expect to record any impairment charge as a result of these operating changes at Taconite 
Harbor  and  Boswell.  In  addition,  we  expect  to  be  able  to  continue  depreciating  these  assets  for  at  least  their  established 
remaining  useful  lives;  however,  we  are  unable  to  predict  the  impact  of  regulatory  outcomes  resulting  in  changes  to  their 
established remaining useful lives. 

NOTE 8.  SHORT-TERM AND LONG-TERM DEBT

Short-Term  Debt.  As  of  December  31,  2022,  total  short-term  debt  outstanding  was  $272.6  million  ($214.2  million  as  of 
December  31,  2021),  and  consisted  of  long-term  debt  due  within  one  year  and  included  $0.1  million  of  unamortized  debt 
issuance costs. 

As  of  December  31,  2022,  we  had  consolidated  bank  lines  of  credit  aggregating  $475.7  million  ($432.0  million  as  of 
December 31, 2021), most of which expire in January 2026. We had $32.8 million outstanding in standby letters of credit and 
$31.3 million outstanding draws under our lines of credit as of December 31, 2022 ($31.5 million in standby letters of credit 
and $159.7 million outstanding draws as of December 31, 2021).

NOTE 8.  SHORT-TERM AND LONG-TERM DEBT (Continued)

Long-Term  Debt.  As  of  December  31,  2022,  total  long-term  debt  outstanding  was  $1,648.2  million  ($1,763.2  million  as  of 
December  31,  2021)  and  included  $8.2  million  of  unamortized  debt  issuance  costs.  The  aggregate  amount  of  long-term  debt 
maturing  in  2023  is  $91.9  million;  $94.8  million  in  2024;  $386.1  million  in  2025;  $79.4  million  in  2026;  $122.5  million  in 
2027;  and  $1,154.4  million  thereafter.  Substantially  all  of  our  regulated  electric  plant  is  subject  to  the  lien  of  the  mortgages 
collateralizing  outstanding  first  mortgage  bonds.  The  mortgages  contain  non-financial  covenants  customary  in  utility 
mortgages, including restrictions on our ability to incur liens, dispose of assets, and merge with other entities.

Minnesota  Power  is  obligated  to  make  financing  payments  for  the  Camp  Ripley  solar  array  totaling  $1.4  million  annually 
during the financing term, which expires in 2027. Minnesota Power has the option at the end of the financing term to renew for 
a  two-year  term,  or  to  purchase  the  solar  array  for  approximately  $4  million.  Minnesota  Power  anticipates  exercising  the 
purchase option when the term expires. 

On  February  28,  2022,  ALLETE  entered  into  an  unsecured  term  loan  agreement  (February  Term  Loan)  to  borrow  up  to 
$175 million. No draws were made on the February Term Loan, which was subsequently terminated in April 2022.  

On March 24, 2022, ALLETE entered into a $170 million unsecured term loan agreement (March Term Loan). The Term Loan 
is  due  March  23,  2023,  and  may  be  repaid  at  any  time.  Interest  is  payable  monthly  at  a  rate  per  annum  equal  to  SOFR  plus 
0.75 percent. Proceeds from the Term Loan were used for general corporate purposes.

On  August  9,  2022,  ALLETE  issued  $75  million  of  its  First  Mortgage  Bonds  (Bonds)  to  certain  institutional  buyers  in  the 
private placement market. The Bonds, which bear interest at 4.54 percent, will mature in August 2032 and pay interest semi-
annually in February and August of each year, commencing on February 9, 2023. ALLETE has the option to prepay all or a 
portion  of  the  Bonds  at  its  discretion,  subject  to  a  make-whole  provision.  The  Bonds  are  subject  to  additional  terms  and 
conditions  which  are  customary  for  these  types  of  transactions.  Proceeds  from  the  sale  of  the  Bonds  were  used  to  refinance 
existing indebtedness and for general corporate purposes. The Bonds were sold in reliance on an exemption from registration 
under Section 4(a)(2) of the Securities Act of 1933, as amended, to institutional accredited investors.

NOTE 8. SHORT-TERM AND LONG-TERM DEBT (Continued)
Long-Term Debt (Continued)

Financial Covenants. Our long-term debt arrangements contain customary covenants. In addition, our lines of credit and letters 
of  credit  supporting  certain  long-term  debt  arrangements  contain  financial  covenants.  Our  compliance  with  financial 
covenants  is  not  dependent  on  debt  ratings.  The  most  restrictive  financial  covenant  requires  ALLETE  to  maintain  a  ratio  of 
indebtedness  to  total  capitalization  (as  the  amounts  are  calculated  in  accordance  with  the  respective  long-term  debt 
arrangements) of less than or equal to 0.65 to 1.00, measured quarterly. As of December 31, 2022, our ratio was approximately 
0.40 to 1.00. Failure to meet this covenant would give rise to an event of default if not cured after notice from the lender, in 
which  event  ALLETE  may  need  to  pursue  alternative  sources  of  funding.  Some  of  ALLETE’s  debt  arrangements  contain 
“cross-default”  provisions  that  would  result  in  an  event  of  default  if  there  is  a  failure  under  other  financing  arrangements  to 
meet  payment  terms  or  to  observe  other  covenants  that  would  result  in  an  acceleration  of  payments  due.  ALLETE  has  no 
significant restrictions on its ability to pay dividends from retained earnings or net income. As of December 31, 2022, ALLETE 
was in compliance with its financial covenants.

(a) Easement obligations represent the minimum payments for our land easement agreements at our wind energy facilities.  
(b) Does not include the Oliver Wind I, Oliver Wind II or Nobles 2 PPAs, as Minnesota Power only pays for energy as it is delivered. (See 

Power Purchase Agreements.)

(c) Consists of long-term service agreements for wind energy facilities and minimum purchase commitments under coal and rail contracts.

Power Purchase and Sales Agreements. Our long-term PPAs have been evaluated under the accounting guidance for variable 
interest  entities.  We  have  determined  that  either  we  have  no  variable  interest  in  the  PPAs,  or  where  we  do  have  variable 
interests, we are not the primary beneficiary; therefore, consolidation is not required. These conclusions are based on the fact 
that  we  do  not  have  both  control  over  activities  that  are  most  significant  to  the  entity  and  an  obligation  to  absorb  losses  or 
receive  benefits  from  the  entity’s  performance.  Our  financial  exposure  relating  to  these  PPAs  is  limited  to  our  capacity  and 
energy payments. 

These agreements have also been evaluated under the accounting guidance for derivatives. We have determined that either these 
agreements  are  not  derivatives,  or,  if  they  are  derivatives,  the  agreements  qualify  for  the  normal  purchases  and  normal  sales 
exception to derivative accounting guidance; therefore, derivative accounting is not required.

Square Butte PPA. Minnesota Power has a PPA with Square Butte that extends through 2026 (Agreement). Minnesota Power is 
obligated  to  pay  its  pro  rata  share  of  Square  Butte’s  costs  based  on  its  entitlement  to  the  output  of  Square  Butte’s  455  MW 
coal-fired generating unit. Minnesota Power’s output entitlement under the Agreement is 50 percent for the remainder of the 
Agreement, subject to the provisions of the Minnkota Power PSA described in the following table. Minnesota Power’s payment 
obligation  will  be  suspended  if  Square  Butte  fails  to  deliver  any  power,  whether  produced  or  purchased,  for  a  period  of  one 
year. Square Butte’s costs consist primarily of debt service, operating and maintenance, depreciation and fuel expenses. As of 
December  31,  2022,  Square  Butte  had  total  debt  outstanding  of  $210.2  million.  Annual  debt  service  for  Square  Butte  is 
expected to be approximately $47.2 million in 2023, $32.2 million in 2024, $28.4 million in 2025, and $28.6 million in 2026 of 
which Minnesota Power’s obligation is 50 percent. Fuel expenses are recoverable through Minnesota Power’s fuel adjustment 
clause and include the cost of coal purchased from BNI Energy under a long-term contract.

Minnesota  Power’s  cost  of  power  purchased  from  Square  Butte  during  2022  was  $82.7  million  ($82.4  million  in  2021; 
$79.5  million  in  2020).  This  reflects  Minnesota  Power’s  pro  rata  share  of  total  Square  Butte  costs  based  on  the  50  percent 
output entitlement. Included in this amount was Minnesota Power’s pro rata share of interest expense of $5.1 million in 2022 
($5.8 million in 2021; $7.1 million in 2020). Minnesota Power’s payments to Square Butte are approved as a purchased power 
expense for ratemaking purposes by both the MPUC and the FERC.

Coal, Rail and Shipping Contracts. Minnesota Power has coal supply agreements providing for the purchase of a significant 
portion of its coal requirements through December 2023. Minnesota Power also has coal transportation agreements in place for 
the  delivery  of  a  significant  portion  of  its  coal  requirements  through  December  2024.  The  costs  of  fuel  and  related 
transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s utility customers through the 
fuel adjustment clause.

Environmental Matters.

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of 
regulatory  changes  to  the  Clean  Air  Act,  the  Clean  Water  Act  and  various  waste  management  requirements  have  been 
promulgated  by  both  the  EPA  and  state  authorities  over  the  past  several  years.  Minnesota  Power’s  facilities  are  subject  to 
additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to 
reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy 
during rulemaking implementation.

We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all 
necessary  permits  have  been  obtained.  We  anticipate  that  with  many  state  and  federal  environmental  regulations  and 
requirements  finalized,  or  to  be  finalized  in  the  near  future,  potential  expenditures  for  future  environmental  matters  may  be 
material  and  require  significant  capital  investments.  Minnesota  Power  has  evaluated  various  environmental  compliance 
scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers.

We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that 
a  liability  has  been  incurred  and  the  amount  of  the  liability  can  be  reasonably  estimated  based  on  current  law  and  existing 
technologies.  Accruals  are  adjusted  as  assessment  and  remediation  efforts  progress,  or  as  additional  technical  or  legal 
information  becomes  available.  Accruals  for  environmental  liabilities  are  included  in  the  Consolidated  Balance  Sheet  at 
undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental 
contamination treatment and cleanup are expensed unless recoverable in rates from customers.

Air.  The  electric  utility  industry  is  regulated  both  at  the  federal  and  state  level  to  address  air  emissions.  Minnesota  Power’s 
thermal  generating  facilities  mainly  burn  low-sulfur  western  sub-bituminous  coal.  All  of  Minnesota  Power’s  coal-fired 
generating  facilities  are  equipped  with  pollution  control  equipment  such  as  scrubbers,  baghouses  and  low  NOX  technologies. 
Under currently applicable environmental regulations, these facilities are substantially compliant with emission requirements.

Cross-State  Air  Pollution  Rule  (CSAPR).  The  CSAPR  requires  certain  states  in  the  eastern  half  of  the  U.S.,  including 
Minnesota, to reduce power plant emissions that contribute to ozone or fine particulate pollution in other states. The CSAPR 
does  not  require  installation  of  controls  but  does  require  facilities  have  sufficient  allowances  to  cover  their  emissions  on  an 
annual basis. These allowances are allocated to facilities from each state’s annual budget, and can be bought and sold. Based on 
our review of the NOX and SO2 allowances issued and pending issuance, we currently expect generation levels and emission 
rates will result in continued compliance with the CSAPR. The EPA’s CSAPR Update Rule issued in March 2021 revising the 
2016  CSAPR  Update  does  not  apply  to  the  state  of  Minnesota  and  is  therefore  not  currently  projected  to  affect  Minnesota 
Power’s  CSAPR  compliance.  Minnesota  Power  will  continue  to  monitor  ongoing  CSAPR  rulemakings  and  compliance 
implementation,  including  the  EPA’s  Good  Neighbor  Rule  proposed  on  April  6,  2022,  to  modify  certain  aspects  of  the 
CSAPR’s program scope and extent.

National Ambient Air Quality Standards (NAAQS). The EPA is required to review the NAAQS every five years. If the EPA 
determines that a state’s air quality is not in compliance with the NAAQS, the state is required to adopt plans describing how it 
will reduce emissions to attain the NAAQS. Minnesota Power actively monitors NAAQS developments and compliance costs 
for existing standards or proposed NAAQS revisions are not currently expected to be material. The EPA is currently reviewing 
the secondary NAAQS for NOx and SO2, as well as particulate matter. In June 2021, the EPA announced it will reconsider the 
December 2020 final rule retaining the 2012 particulate matter NAAQS. On January 6, 2023 the EPA announced a proposed 
rule  to  revise  the  primary  annual  particulate  matter  NAAQS  from  its  current  level  while  retaining  the  other  primary  and 
secondary particulate matter NAAQS. A final rule is expected by the end of 2023. The EPA also announced in October 2021 
that  it  was  reconsidering  the  2020  Ozone  NAAQS  rule  finalized  in  December  2020,  and  issued  a  policy  assessment  on 
April 28, 2022, recommending retention of the current standard. A proposed Ozone NAAQS rule is expected in the first half of 
2023. Anticipated compliance costs related to the proposed and expected NAAQS revisions cannot yet be estimated; however, 
costs could be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

EPA Good Neighbor Plan for 2015 Ozone NAAQS. On April 6, 2022, the EPA published a proposed rule, the Good Neighbor 
Plan, to address regional ozone transport for the 2015 Ozone NAAQS by reducing NOx emissions during the period of May 1 
through September 30 (ozone season). This rule is intended to address certain good neighbor or interstate transport provisions 
of  the  Clean  Air  Act  relative  to  the  2015  Ozone  NAAQS.  In  the  justification  for  the  proposed  rule,  the  EPA  asserted  that 
26  states,  including  Minnesota,  are  modeled  as  significant  contributors  to  downwind  states’  challenges  in  attaining  or 
maintaining ozone NAAQS compliance within their state borders. The Good Neighbor Plan proposes to resolve this interstate 
transport issue by implementing a variety of NOx reduction strategies, including federal implementation plan requirements, NOx 
emission limitations, and ozone season allowance program requirements, beginning with the 2023 ozone season. The proposed 
rule would apply to fossil-fuel fired power plants in 25 states and certain other industrial sources in 23 states. Implementation of 
the rule would occur in part through changes to the existing CSAPR program. 

Minnesota  Power  reviewed  the  proposed  rule,  assessed  its  potential  impacts  and  submitted  public  comments  to  the  EPA  on 
June  21,  2022.  Concerns  noted  by  Minnesota  Power  and  other  entities  included  the  technical  accuracy  of  the  EPA’s 
assumptions and methods used to identify Minnesota as a significant contributor state, as well as the proposed rule’s intended 
timeline. Anticipated compliance costs related to the Good Neighbor Plan cannot yet be estimated; however, the costs could be 
material, including costs of additional NOx controls, emission allowance program participation, or operational changes, if any 
are required. Minnesota Power would seek recovery of additional costs through a rate proceeding. The EPA intends to issue a 
final  rule  in  early  2023,  following  a  final  action  to  approve  or  disapprove  the  ozone  transport  State  Implementation  Plans 
(SIPs). On January 31, 2023, the EPA announced its final action to partially disapprove SIPs for the states of Minnesota and 
Wisconsin,  and  to  disapprove  19  other  SIP  submissions.  The  Company  is  currently  reviewing  this  SIP  final  action  and  any 
associated  costs  cannot  yet  be  anticipated  until  the  issuance  of  the  EPA’s  final  Good  Neighbor  Plan,  which  is  expected  in 
March 2023.

EPA National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial and Institutional 
Boilers  and  Process  Heaters  (Industrial  Boiler  MACT)  Rule.  A  final  rule  issued  by  the  EPA  for  Industrial  Boiler  MACT 
became effective in 2013 with compliance required at major existing sources in 2016. Minnesota Power’s Hibbard Renewable 
Energy Center and Rapids Energy Center are subject to this rule. Compliance with the Industrial Boiler MACT Rule consisted 
largely  of  adjustments  to  fuels  and  operating  practices  and  compliance  costs  were  not  material.  Subsequent  to  this  initial 
rulemaking, litigation from 2016 through 2018 resulted in court orders directing that the EPA reconsider certain aspects of the 
regulation  including  the  basis  for  and  numerical  value  of  several  different  emission  limits.  On  October  6,  2022,  the  EPA 
published  a  final  rule  in  the  Federal  Register  incorporating  these  changes.  The  rule  became  effective  on  December  5,  2022, 
imposing a 3-year compliance deadline of October 6, 2025. Minnesota Power’s initial review of this new rule indicates that the 
revisions  should  not  significantly  impact  the  Company’s  affected  units.  As  such,  compliance  costs  associated  with  the  new 
Industrial  Boiler  MACT  Rule  are  not  currently  expected  to  be  material;  however  Minnesota  Power  would  seek  recovery  of 
additional costs through a rate proceeding.

Climate  Change.  The  scientific  community  generally  accepts  that  emissions  of  GHGs  are  linked  to  global  climate  change 
which  creates  physical  and  financial  risks.  Physical  risks  could  include,  but  are  not  limited  to:  increased  or  decreased 
precipitation and water levels in lakes and rivers; increased or other changes in temperatures; increased risk of wildfires; and 
changes in the intensity and frequency of extreme weather events. These all have the potential to affect the Company’s business 
and operations. We are addressing climate change by taking the following steps that also ensure reliable and environmentally 
compliant generation resources to meet our customers’ requirements:

•
•
•
•

•

Expanding renewable power supply for both our operations and the operations of others;
Providing energy conservation initiatives for our customers and engaging in other demand side management efforts;
Improving efficiency of our generating facilities;
Supporting  research  of  technologies  to  reduce  carbon  emissions  from  generating  facilities  and  carbon  sequestration 
efforts; 
Evaluating and developing less carbon intensive future generating assets such as efficient and flexible natural gas-fired 
generating facilities;

• Managing vegetation on right-of-way corridors to reduce potential wildfire or storm damage risks; and
•

Practicing sound forestry management in our service territories to create landscapes more resilient to disruption from 
climate-related changes, including planting and managing long-lived conifer species.

EPA  Regulation  of  GHG  Emissions.  In  2019,  the  EPA  finalized  several  separate  rulemakings  regarding  regulating  carbon 
emissions  from  electric  utility  generating  units.  These  rulemakings  included  repealing  the  Clean  Power  Plan  (CPP)  and 
adopting  the  Affordable  Clean  Energy  Rule  under  Section  111(d)  of  the  Clean  Air  Act  (CAA)  to  regulate  CO2  emissions  at 
existing coal-fired power plants. The CPP was first announced as a proposed rule under Section 111(d) of the CAA for existing 
power plants entitled “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units”. The 
Affordable Clean Energy Rule established emissions guidelines for states to use when developing plans to limit CO2 from coal-
fired power plants. The EPA also published regulations for the state implementation of the Affordable Clean Energy Rule and 
other Section 111(d) rules. Affected facilities for Minnesota Power included Boswell Units 3 and 4, Hibbard Units 3 and 4, and 
Taconite Harbor Units 1 and 2; Taconite Harbor Units 1 and 2 are currently economically idled.

In January 2021, the D.C. Circuit issued an opinion vacating the Affordable Clean Energy Rule and remanded the Affordable 
Clean Energy Rule back to the EPA for further consideration, consistent with the D.C. Circuit’s finding that the EPA erred in 
interpreting the CAA, pending rehearing or appeal. Four petitions for review of the D.C. Circuit’s opinion were subsequently 
granted by the U.S. Supreme Court in October 2021, consolidated under West Virginia v. EPA et al. On June 30, 2022, the U.S. 
Supreme Court released its opinion in favor of West Virginia and aligned parties. The Supreme Court found the EPA’s CPP 
structure of generation shifting to be disallowed under Section 111(d) of the CCA on grounds of the major questions doctrine. 
The court did not opine upon the regulatory approach the EPA proposed in the Affordable Clean Energy Rule. The petitions 
were remanded to the D.C. Circuit. The EPA has indicated that it intends to issue a proposed rule in early 2023 with a new set 
of emission guidelines for states to follow in submitting state plans to establish and implement standards of performance for 
GHG emissions from existing fossil fuel-fired electric generating units. Minnesota Power will continue to monitor any related 
guidelines and rulemakings issued by the EPA or state regulatory authorities.

In April 2021, the Biden Administration announced a goal to reach 100 percent carbon pollution-free electricity by 2035 as part 
of the Nationally Determined Contributions pledge, which is part of an international effort to limit global warming. At this time, 
no specific regulatory pathway to achieve these reductions has been proposed. Minnesota Power will continue to monitor these 
developments.

Minnesota  had  already  initiated  several  measures  consistent  with  those  called  for  under  the  now  repealed  CPP  and  vacated 
Affordable  Clean  Energy  Rule.  Minnesota  Power  continues  implementing  its  EnergyForward  strategic  plan  that  provides  for 
significant emission reductions and diversifying its electricity generation mix to include more renewable and natural gas energy. 
We are unable to predict the GHG emission compliance costs we might incur as a result of a replacement for the Affordable 
Clean Energy Rule or other future laws, regulations or administrative policies; however, the costs could be material. Minnesota 
Power would seek recovery of additional costs through a rate proceeding.

Additionally in January 2021, the EPA issued a rulemaking to apply CO2 emission New Source Performance Standards (NSPS) 
to new, modified and reconstructed fossil fuel-fired electric generating units under Section 111(b) of the CAA. Currently, the 
EPA is a performing a comprehensive review of the Section 111(b) GHG NSPS for electric generating units, with a notice of 
proposed  rulemaking  expected  in  early  2023.  Minnesota  Power  is  monitoring  the  NSPS  final  rule  and  any  further  Section 
111(b)  developments  including  their  potential  impact  to  the  Company.  The  proposed  combined-cycle  natural  gas-fired 
generating facility, NTEC, is expected to meet these NSPS requirements.

Water.  The  Clean  Water  Act  requires  NPDES  permits  be  obtained  from  the  EPA  (or,  when  delegated,  from  individual  state 
pollution  control  agencies)  for  any  wastewater  discharged  into  navigable  waters.  We  have  obtained  all  necessary  NPDES 
permits, including NPDES storm water permits for applicable facilities, to conduct our operations.

Steam Electric Power Generating Effluent Limitations Guidelines. In 2015, the EPA issued revised federal effluent limitation 
guidelines (ELG) for steam electric power generating stations under the Clean Water Act. It set effluent limits and prescribed 
BACT for several wastewater streams, including flue gas desulphurization (FGD) water, bottom ash transport water and coal 
combustion  landfill  leachate.  In  2017,  the  EPA  announced  a  two-year  postponement  of  the  ELG  compliance  date  of 
November  1,  2018,  to  November  1,  2020,  while  the  agency  reconsidered  the  bottom  ash  transport  water  (BATW)  and  FGD 
wastewater provisions. On April 12, 2019, the U.S. Court of Appeals for the Fifth Circuit vacated and remanded back to the 
EPA portions of the ELG that allowed for continued discharge of legacy wastewater and leachate. On October 13, 2020, the 
EPA  published  a  final  ELG  Rule  allowing  re-use  of  bottom  ash  transport  water  in  FGD  scrubber  systems  with  limited 
discharges related to maintaining system water balance. The rule sets technology standards and numerical pollutant limits for 
discharges of bottom ash transport water and FGD wastewater. Compliance deadlines depend on subcategory, with compliance 
generally  required  as  soon  as  possible,  beginning  after  October  13,  2021,  but  no  later  than  December  31,  2025,  or 
December  31,  2028,  in  some  specific  cases.  The  rule  also  established  new  subcategories  for  retiring  high-flow  and  low-
utilization  units,  and  established  a  voluntary  incentives  program  for  FGD  wastewater.  In  accordance  with  the  January  2021 
Executive  Order  13990,  the  EPA  was  mandated  to  conduct  a  review  of  actions  and  polices  taken  during  the  prior 
administration,  including  the  2020  ELG  Rule.  On  September  14,  2021,  the  EPA  published  a  notice  of  availability  for  its 
preliminary effluent guidelines program plan. In the plan, the EPA confirmed the agency is initiating a rulemaking process to 
strengthen  wastewater  pollution  limitations  from  FGD  and  bottom  ash  transport  water  discharges  while  the  2020  ELG  Rule 
remains in effect. The EPA is expected to publish a proposed rule in 2023.

Under  the  2020  ELG  rule,  most  bottom  ash  transport  water  discharge  to  surface  waters  must  cease  no  later  than 
December 31, 2025, except for small discharges needed to retain water balance. The majority of bottom ash transport will either 
need to be re-used in a closed-loop process or routed to a FGD scrubber. FGD wastewater is required to meet stringent water 
quality standards for discharge to surface water.

Bottom ash transport and FGD wastewater ELG’s are not currently expected to have a significant impact on Minnesota Power 
operations. Boswell Energy Center, where ELG’s are primarily applicable, completed conversion to dry bottom ash handling 
and installed a FGD dewatering system in September 2022. The dry conversion projects eliminated bottom ash transport water 
and  minimized  wastewater  from  the  FGD  system.  Re-use  and  onsite  consumption  is  planned  for  the  remaining  FGD  waste 
stream and for dewatering legacy wastewater from Boswell’s existing impoundments. Water re-use and consumption activities 
are expected to eliminate the need for surface water discharges prior to the current ELG Rule deadline of December 31, 2025.

The  EPA’s  additional  reconsideration  of  legacy  wastewater  and  leachate  discharge  requirements  has  the  potential  to  impact 
leachate  discharges  associated  with  the  closed  impoundment  at  the  Laskin  and  Taconite  Harbor  Energy  Centers  Dry  Ash 
Landfill. In its spring 2022 Unified Agenda, the EPA announced it intends to consolidate consideration of legacy wastewater 
and leachate with the ELG/FGD and BATW proposed rulemaking currently expected in 2023. It is unknown at this time if the 
rule revisions will include new requirements for these waste streams.

At  this  time,  we  estimate  no  additional  material  compliance  costs  for  ELG  bottom  ash  water  and  FGD  requirements. 
Compliance costs we might incur related to other ELG waste streams (e.g., leachate) or other potential future water discharge 
regulations at Minnesota Power facilities cannot be estimated; however, the costs could be material, including costs associated 
with wastewater treatment and re-use. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Permitted  Water  Discharges  –  Sulfate.  In  2017,  the  MPCA  released  a  draft  water  quality  standard  in  an  attempt  to  update 
Minnesota’s existing 10 mg/L sulfate limit for waters used for the production of wild rice with the proposed rulemaking heard 
before an administrative law judge (ALJ). In 2018, the ALJ rejected significant portions of the proposed rulemaking and the 
MPCA  subsequently  withdrew  the  rulemaking.  The  existing  10  mg/L  limit  remains  in  place,  but  the  MPCA  is  currently 
prohibited under state law from listing wild rice waters as impaired or requiring sulfate reduction technology. 

In April 2021, the MPCA’s proposed list of impaired waters submitted pursuant to the Clean Water Act was partially rejected 
by the EPA due to the absence of wild rice waters listed for sulfate impairment. The EPA transmitted a final list of 32 EPA-
added wild rice waters to the MPCA in November 2021. This list could subsequently be used to set sulfate limits in discharge 
permits for power generation facilities and municipal and industrial customers, including paper and pulp facilities, and mining 
operations.  At  this  time  we  are  unable  to  determine  the  specific  impacts  these  developments  may  have  on  Minnesota  Power 
operations, if any. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Solid and Hazardous Waste. The Resource Conservation and Recovery Act of 1976 regulates the management and disposal of 
solid and hazardous wastes. We are required to notify the EPA of hazardous waste activity and, consequently, routinely submit 
reports to the EPA.

Coal Ash Management Facilities. Minnesota Power produces the majority of its coal ash at Boswell, with small amounts of ash 
generated  at  Hibbard  Renewable  Energy  Center.  Ash  storage  and  disposal  methods  include  storing  ash  in  clay-lined  onsite 
impoundments (ash ponds), disposing of dry ash in a lined dry ash landfill, applying ash to land as an approved beneficial use, 
and trucking ash to state permitted landfills. 

Coal  Combustion  Residuals  from  Electric  Utilities  (CCR).  In  2015,  the  EPA  published  the  final  rule  (2015  Rule)  regulating 
CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act (RCRA) in the Federal Register. 
The rule includes additional requirements for new landfill and impoundment construction as well as closure activities related to 
certain existing impoundments. Costs of compliance for Boswell and Laskin are expected to be incurred primarily over the next 
15 years and be between approximately $65 million and $120 million. Compliance costs for CCR at Taconite Harbor are not 
expected to be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Minnesota  Power  continues  to  work  on  minimizing  costs  through  evaluation  of  beneficial  re-use  and  recycling  of  CCR  and 
CCR-related  waters.  In  2017,  the  EPA  announced  its  intention  to  formally  reconsider  the  CCR  rule  under  Subtitle  D  of  the 
RCRA. In March 2018, the EPA published the first phase of the proposed rule revisions in the Federal Register. In 2018, the 
EPA finalized revisions to elements of the CCR rule, including extending certain deadlines by two years, the establishment of 
alternative  groundwater  protection  standards  for  certain  constituents  and  the  potential  for  risk-based  management  options  at 
facilities  based  on  site  characteristics.  In  2018,  a  U.S.  District  Court  for  the  District  of  Columbia  decision  vacated  specific 
provisions of the CCR rule. The court decision resulted in a change to the status of three existing clay-lined impoundments at 
Boswell  that  must  now  be  considered  unlined.  The  EPA  proposed  additional  rule  revisions  in  2019  to  address  outstanding 
issues from litigation and closure timelines for unlined impoundments, respectively. The first of these rules, CCR Part A Rule, 
was finalized in September 2020. The Part A Rule revision requires unlined impoundments to cease disposal of waste as soon 
as technically feasible but no later than April 11, 2021. Minnesota Power sought EPA approval under the Part A Rule to extend 
the closure date for two active Boswell impoundments in November 2020. Upon completion of dry ash conversion activities, 
Boswell ceased disposal in both impoundments on September 17, 2022 and formally withdrew the CCR Part A Application. 
The EPA acknowledged the Part A variance application withdrawal on September 20, 2022, and indicated that no further EPA 
review of Boswell’s Part A variance application will occur. Both impoundments are now inactive and have initiated closure.

Additionally, the EPA released a proposed Part B rulemaking in February 2020 addressing options for beneficial reuse of CCR 
materials,  alternative  liner  demonstrations,  and  other  CCR  regulatory  revisions.  Portions  of  the  Part  B  Rule  addressing 
alternative liner equivalency standards were finalized in November 2020. According to the EPA’s updated fall 2022 regulatory 
agenda, finalization of the remainder of the proposed Part B Rule is expected in late 2023. Two additional rulemakings are also 
expected in mid-2023, the proposed Legacy Impoundment Rule and the Final Federal Permit Rule. The Legacy Impoundment 
Rule will include a revised definition for legacy CCR Impoundments which could regulate impoundments that had closed prior 
to the effective date of the 2015 Rule. The Final Federal Permit Rule will finalize procedures for implementing a CCR Federal 
Permit  Program.  Expected  compliance  costs  at  Boswell  due  to  the  2018  court  decision  and  subsequent  rule  revisions  are 
reflected in our estimate of compliance costs for the CCR rule noted previously.

(a) For the years ended December 31, 2021 and 2020, the federal and state current tax expense was minimal due to NOLs which resulted 
from the bonus depreciation provisions of certain tax legislation. Federal and state NOLs are being carried forward to offset current 
and future taxable income. For the year ended December 31, 2022, federal NOLs were fully utilized and production tax credits were 
used to partially offset federal taxable income.

(b) For the years ended December 31, 2022, 2021 and 2020, the federal tax benefit is primarily due to production tax credits.
(c) For  the  year  ended  December  31,  2022,  the  state  impact  includes  the  benefit  of  deferred  repricing  as  a  result  of  the  New  Energy 

acquisition.

(a) Excess  deferred  income  taxes  are  being  returned  to  customers  under  both  the  Average  Rate  Assumption  Method  and  amortization 

periods as approved by regulators. (See Note 4. Regulatory Matters.)

The effective tax rate was a benefit of 31.2 percent for 2022 (benefit of 24.3 percent for 2021; benefit of 39.7 percent for 2020). 
The  2022  and  2021  effective  tax  rates  were  primarily  impacted  by  production  tax  credits  and  non-controlling  interests  in 
subsidiaries. The 2020 effective tax rate was primarily impacted by production tax credits.

Unrecognized tax benefits are the differences between a tax position taken or expected to be taken in a tax return and the benefit 
recognized  and  measured  pursuant  to  the  “more-likely-than-not”  criteria.  The  unrecognized  tax  benefit  balance  includes 
permanent tax positions which, if recognized would affect the annual effective income tax rate. 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 effective tax rate 
but would accelerate the payment of cash to the taxing authority to an earlier period. The gross unrecognized tax benefits as of 
December  31,  2022,  included  $0.6  million  of  net  unrecognized  tax  benefits  which,  if  recognized,  would  affect  the  annual 
effective income tax rate. 

As  of  December  31,  2022,  we  had  immaterial  accrued  interest  (none  as  of  December  31,  2021,  and  2020)  related  to 
unrecognized  tax  benefits  included  on  the  Consolidated  Balance  Sheet  due  to  our  NOL  carryforwards.  We  classify  interest 
related  to  unrecognized  tax  benefits  as  interest  expense  and  tax-related  penalties  in  operating  expenses  on  the  Consolidated 
Statement  of  Income.  Interest  expense  related  to  unrecognized  tax  benefits  on  the  Consolidated  Statement  of  Income  was 
immaterial in 2022, 2021 and 2020. There were no penalties recognized in 2022, 2021 or 2020. The unrecognized tax benefit 
amounts have been presented as an increase to the net deferred tax liability on the Consolidated Balance Sheet.

No material changes to unrecognized tax benefits are expected during the next 12 months.

ALLETE and its subsidiaries file a consolidated federal income tax return as well as combined and separate state income tax 
returns  in  various  jurisdictions.  ALLETE  is  currently  under  examination  by  the  state  of  Wisconsin  for  the  tax  years  2018 
through 2020. ALLETE has no open federal audits, and is no longer subject to federal examination for years before 2019 or 
state examination for years before 2018. Additionally, the statute of limitations related to the federal tax credit carryforwards 
will remain open until those credits are utilized in subsequent returns.

NOTE 12.  PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

We  have  noncontributory  union,  non-union  and  combined  retiree  defined  benefit  pension  plans  covering  eligible  employees. 
The combined retiree defined benefit pension plan was created in 2016, to include all union and non-union retirees from the 
existing plans as of January 2016. The plans provide defined benefits based on years of service and final average pay. We made 
no contributions to the plan trusts in 2022 ($10.3 million in 2021; $10.7 million in 2020). We also have a defined contribution 
RSOP covering substantially all employees. The 2022 plan year employer contributions totaled $12.0 million ($11.5 million for 
the 2021 plan year; $11.2 million for the 2020 plan year). (See Note 10. Common Stock and Earnings Per Share and Note 13. 
Employee Stock and Incentive Plans.) 

The non-union defined benefit pension plan was frozen in 2018, and does not allow further crediting of service or earnings to 
the plan. Further, it is closed to new participants. The Minnesota Power union defined benefit pension plan is also closed to new 
participants, and the SWL&P union defined benefit pension plan was closed to new participants effective February 1, 2022. 

We have postretirement health care and life insurance plans covering eligible employees. In 2010, the postretirement health care 
plan  was  closed  to  employees  hired  after  January  2011,  and  the  eligibility  requirements  were  amended.  In  2014,  the 
postretirement life plan was amended to close the plan to non-union employees retiring after December 2015, and in 2018, the 
postretirement  life  plan  was  amended  to  limit  the  benefit  level  for  union  employees  retiring  after  December  2018.  The 
postretirement health and life plans are contributory with participant contributions adjusted annually. Postretirement health and 
life benefits are funded through a combination of Voluntary Employee Benefit Association trusts (VEBAs), established under 
section  501(c)(9)  of  the  Internal  Revenue  Code,  and  irrevocable  grantor  trusts.  In  2022,  no  contributions  were  made  to  the 
VEBAs (none in 2021; none in 2020) and no contributions were made to the grantor trusts (none in 2021; none in 2020).

Management considers various factors when making funding decisions such as regulatory requirements, actuarially determined 
minimum contribution requirements and contributions required to avoid benefit restrictions for the pension plans. Contributions 
are based on estimates and assumptions which are subject to change. On January 17, 2023, we contributed $6.5 million in cash 
to the defined benefit pension plans. We do not expect to make any further contributions to the defined benefit pension plans in 
2023, and we do not expect to make any contributions to the defined benefit postretirement health and life plans in 2023.

Accounting  for  defined  benefit  pension  and  other  postretirement  benefit  plans  requires  that  employers  recognize  on  a 
prospective basis the funded status of their defined benefit pension and other postretirement plans on their balance sheet and 
recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that 
arise during the period but are not recognized as components of net periodic benefit cost.

The  defined  benefit  pension  and  postretirement  health  and  life  benefit  expense  (credit)  recognized  annually  by  our  regulated 
utilities are expected to be recovered (refunded) through rates filed with our regulatory jurisdictions. As a result, these amounts 
that are required to otherwise be recognized in accumulated other comprehensive income have been recognized as a long-term 
regulatory asset (regulatory liability) on the Consolidated Balance Sheet, in accordance with the accounting standards for the 
effect  of  certain  types  of  regulation  applicable  to  our  Regulated  Operations.  The  defined  benefit  pension  and  postretirement 
health  and  life  benefit  expense  (credits)  associated  with  our  other  operations  are  recognized  in  accumulated  other 
comprehensive income.

In establishing the expected long-term rate of return on plan assets, we determine the long-term historical performance of each 
asset  class,  adjust  these  for  current  economic  conditions,  and  utilizing  the  target  allocation  of  our  plan  assets,  forecast  the 
expected long-term rate of return.

The discount rate is computed using a bond matching study which utilizes a portfolio of high quality bonds that produce cash 
flows similar to the projected costs of our pension and other postretirement plans. 

The Company utilizes actuarial assumptions about mortality to calculate the pension and postretirement health and life benefit 
obligations.  The  mortality  assumptions  used  to  calculate  our  pension  and  other  postretirement  benefit  obligations  as  of 
December 31, 2022, considered a modified PRI-2012 mortality table and MP-2021 mortality projection scale.

There were no shares of ALLETE common stock included in pension plan equity securities as of December 31, 2022 (no shares 
as of December 31, 2021).

The  defined  benefit  pension  plans  have  adopted  a  dynamic  asset  allocation  strategy  (glide  path)  that  increases  the  invested 
allocation to fixed income assets as the funding level of the plan increases to better match the sensitivity of the plan’s assets and 
liabilities  to  changes  in  interest  rates.  This  is  expected  to  reduce  the  volatility  of  reported  pension  plan  expenses.  The 
postretirement health and life plans’ assets are diversified to achieve strong returns within managed risk. Equity securities are 
diversified among domestic companies with large, mid and small market capitalizations, as well as investments in international 
companies. The majority of debt securities are made up of investment grade bonds. 

Following are the current targeted allocations as of December 31, 2022:

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between 
market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would 
use  in  pricing  the  asset  or  liability,  including  assumptions  about  risk  and  the  risks  inherent  in  the  inputs  to  the  valuation 
technique.  These  inputs  can  be  readily  observable,  market  corroborated,  or  generally  unobservable.  We  primarily  apply  the 
market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we 
utilize  valuation  techniques  that  maximize  the  use  of  observable  inputs  and  minimize  the  use  of  unobservable  inputs.  These 
inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest 
priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest 
priority to unobservable inputs (Level 3 measurement). (See Note 7. Fair Value.)

Accounting  and  disclosure  requirements  for  the  Medicare  Prescription  Drug,  Improvement  and  Modernization  Act  of  2003 
(Act) provide guidance for employers that sponsor postretirement health care plans that provide prescription drug benefits. We 
provide  a  fully  insured  postretirement  health  benefit,  including  a  prescription  drug  benefit,  which  qualifies  us  for  a  federal 
subsidy under the Act. The federal subsidy is reflected in the premiums charged to us by the insurance company.

NOTE 13.  EMPLOYEE STOCK AND INCENTIVE PLANS

Employee Stock Ownership Plan. We sponsor an ESOP within the RSOP. Eligible employees may contribute to the RSOP 
plan as of their date of hire. The dividends received by the ESOP are distributed to participants. Dividends on allocated ESOP 
shares are recorded as a reduction of retained earnings. ESOP employer allocations are funded with contributions paid in either 
cash or the issuance of ALLETE common stock at the Company’s discretion. We record compensation expense equal to the 
cash  or  current  market  price  of  stock  contributed.  ESOP  compensation  expense  was  $12.0  million  in  2022  ($11.5  million  in 
2021; $11.2 million in 2020).

According  to  the  accounting  standards  for  stock  compensation,  unallocated  shares  of  ALLETE  common  stock  held  and 
purchased  by  the  ESOP  were  treated  as  unearned  ESOP  shares  and  not  considered  outstanding  for  earnings  per  share 
computations. All ESOP shares have been allocated to participants as of December 31, 2022, 2021 and 2020.

Stock-Based Compensation. 

Stock Incentive Plan. Under our Executive Long-Term Incentive Compensation Plan (Executive Plan), share-based awards may 
be  issued  to  key  employees  through  a  broad  range  of  methods,  including  non-qualified  and  incentive  stock  options, 
performance shares, performance units, restricted stock, restricted stock units, stock appreciation rights and other awards. There 
are 0.8 million shares of ALLETE common stock reserved for issuance under the Executive Plan, of which 0.6 million of these 
shares remain available for issuance as of December 31, 2022.

NOTE 13.  EMPLOYEE STOCK AND INCENTIVE PLANS (Continued)
Stock-Based Compensation (Continued)

The following types of share-based awards were outstanding in 2022, 2021 or 2020:

Performance  Shares.  Under  the  performance  share  awards,  the  number  of  shares  earned  is  contingent  upon  attaining 
specific  market  and  performance  goals  over  a  three-year  performance  period.  Market  goals  are  measured  by  total 
shareholder  return  relative  to  a  group  of  peer  companies  while  performance  goals  are  measured  by  earnings  per  share 
growth. In the case of qualified retirement, death, or disability during a performance period, a pro rata portion of the award 
will be earned at the conclusion of the performance period based on the market goals achieved. In the case of termination 
of employment for any reason other than qualified retirement, death, or disability, no award will be earned. If there is a 
change in control, a pro rata portion of the award will be paid based on the greater of actual performance up to the date of 
the change in control or target performance. The fair value of these awards incorporates the probability of meeting the total 
shareholder return goals. Compensation cost is recognized over the three-year performance period based on our estimate of 
the number of shares which will be earned by the award recipients.

Restricted Stock Units. Under the restricted stock unit awards, shares for participants eligible for retirement vest monthly 
over a three-year period. For participants not eligible for retirement, shares vest at the end of the three-year period. In the 
case of qualified retirement, death or disability, a pro rata portion of the award will be earned. In the case of termination of 
employment for any reason other than qualified retirement, death or disability, no award will be earned. If there is a change 
in control, a pro rata portion of the award will be earned. The fair value of these awards is equal to the grant date fair value. 
Compensation cost is recognized over the three-year vesting period based on our estimate of the number of shares which 
will be earned by the award recipients.

Employee Stock Purchase Plan (ESPP). Under our ESPP, eligible employees may purchase ALLETE common stock at a 
5 percent discount from the market price; we are not required to apply fair value accounting to these awards as the discount 
is not greater than 5 percent.

RSOP. The RSOP is a contributory defined contribution plan subject to the provisions of the Employee Retirement Income 
Security Act of 1974, as amended, and qualifies as an employee stock ownership plan and profit sharing plan. The RSOP 
provides eligible employees an opportunity to save for retirement.

The following share-based compensation expense amounts were recognized in our Consolidated Statement of Income for the 
periods presented.
