  Minnesota Power Outlines its EnergyForward Resource Strategy

            A better-balanced power supply for future generations

DULUTH, Minn. -- January 30, 2013

Minnesota Power, a division of ALLETE (NYSE:ALE), today outlined next steps in
its resource strategy to meet the energy needs of its customers with a
balanced energy mix that preserves reliability, protects affordability and
further improves environmental performance.

“Minnesota Power’s EnergyForward resource strategy is our road map to a
cleaner energy future,” said ALLETE Chairman, President and CEO Al Hodnik.
“Our plan keeps pace with a dynamic energy landscape in a sensible and
sustainable manner. EnergyForward builds upon renewable energy investments
already completed. It further diversifies our generation mix, balancing coal,
renewables and natural gas and builds upon significant emission reductions at
our existing power plants, all while preserving the reliable and affordable
power Minnesota Power’s customers expect.”

Components of Minnesota Power’s EnergyForward resource strategy:

  *Renewable energy investments
  *Sustained energy conservation programs
  *Construction of a major transmission line to facilitate delivery of carbon
    free hydropower
  *Investments to reduce emissions at existing facilities and improve
  *Fleet transition of small coal units
  *Addition of natural gas resources

“The resource decisions we are announcing today are the result of changing
energy policy, technology developments, economic factors and input from many
stakeholder groups, and our own commitment toward a competitive,
environmentally compliant, socially responsible regional power supply,” Hodnik

Significant renewable carbon free energy investments

Now that it’s completed three phases of the Bison Wind Project in North
Dakota, Minnesota Power is delivering more than 400 megawatts of clean,
renewable wind energy to customers. With the recent extension of the federal
production tax credit on wind generation equipment, the company is analyzing
adding more wind to its energy mix.

Minnesota Power will further leverage its renewable resources through a power
purchase agreement with Manitoba Hydro for 250 megawatts of hydropower
beginning in 2020. The company is proposing to deliver the carbon free energy
on a new 500-kilovolt transmission line stretching from the Canadian border to
northeastern Minnesota, expected to be completed by 2020.

“Our plan builds on the tremendous progress we’ve made to achieve a more
balanced and sustainable energy mix in a cost competitive manner,” Hodnik
said. “Our North Dakota wind operations have more than tripled the amount of
renewable energy on our system in a short time, moving our power supply from 5
percent renewable energy in 2005, to 20 percent this year.”

As part of its EnergyForward plan, Minnesota Power will upgrade the largest
hydroelectric system in the state, by increasing efficiencies at its Thomson
and Fond du Lac hydroelectric stations. At the same time, the company will
continue its leading-edge Power of One© conservation program which has
exceeded state conservation goals by providing customers with tools to lower
their energy usage.

Reducing emissions and improving efficiencies through technology investments

Minnesota Power plans to invest approximately $350 million in additional
environmental upgrades at its largest electric generator, Boswell Energy
Center Unit 4, to comply with the EPA Mercury Air Toxics Standard (MATS) and
the Minnesota Mercury Emission Reduction Act, resulting in at least a 90
percent reduction in mercury emissions. These upgrades, combined with other
emission reduction investments made since 2006, will result in system-wide
emission reductions of more than 85 percent by 2016. Boswell 4 in 2010 made
major nitrogen oxide emission reductions and increased its operating
efficiency with new turbine rotor investments.

Fleet transition

Over the last year, the company explored alternatives for its small coal units
including retrofitting, refueling and retirement against the backdrop of
environmental regulations and historically low natural gas prices. Careful
consideration of power supply options led to the decision to refuel or remove
from service one-third of its coal energy conversion units. These plans

  *Investing $15 million to convert the company’s 110-megawatt (MW) Laskin
    Energy Center in Hoyt Lakes to a natural gas peaking facility in 2015,
    thereby transforming Laskin into the company’s first all-natural gas
    fueled facility.
  *Retire one of three coal-fired units at Minnesota Power’s 225-MW Taconite
    Harbor facility in Schroeder while maintaining Units 1 and 2, which both
    comply with current and pending environmental regulations.

“We believe re-fueling Laskin and retiring one generating unit at our Taconite
Harbor facility are the most cost effective solutions for our small coal units
to comply with state and federal regulations,” said Minnesota Power Vice
President of Strategy and Planning Al Rudeck.

“The Laskin and Taconite Harbor facilities have provided reliable service and
proven their value for customers over many decades, operated by talented and
dedicated employees,” Hodnik said. “Like many employers in our region,
Minnesota Power is experiencing a significant workforce transition now and for
several years ahead,” Hodnik said. “Every effort will be made to redeploy
skilled employees from affected facilities across our system, as EnergyForward

Natural gas additions

As part of its EnergyForward plan, the company expects to add natural gas to
its long-term power supply beyond the Laskin conversion to natural gas fuel.
“We expect this next resource addition to occur sometime in 2020 or beyond,”
Rudeck said. He said Minnesota Power’s energy mix in the future would consist
of approximately one-third renewable energy, one-third natural gas and one-
third coal-fired generation.

“For more than a century, Minnesota Power has been called upon to make the
critical decisions that power our region’s communities, businesses and
industry reliably and economically,” Hodnik said. “We recognize our
responsibility to this region’s security, comfort and quality of life and that
commitment will continue under our EnergyForward plan.”

Minnesota Power’s energy resource decisions and ongoing plans for fleet
transition are subject to review and approval by the Minnesota Public
Utilities Commission. As part of its EnergyForward plan, Minnesota Power will
file its next Integrated Resource Plan (IRP) with the Minnesota Public
Utilities Commission on March 1. The MPUC is anticipated to make a decision on
the IRP by year end.
