Financial Overview

(See Note 2 - Business Segments for financial results by segment.)

The following income discussion summarizes, by segment, a comparison of the six months ended June 30, 2008, to the six months ended June 30, 2007.

Regulated Utility contributed income of $23.3 million in 2008 ($24.9 million in 2007). The decrease in earnings is primarily the result of the expiration of sales contracts to Other Power Suppliers and an increase in operating expense, depreciation expense and interest expense. These factors were partially offset by increased revenues attributable to current cost recovery on our environmental retrofit projects, new FERC approved wholesale rates, and higher retail and municipal kilowatt-hour sales.

Nonregulated Energy Operations contributed income of $1.4 million in 2008 ($2.8 million in 2007). The decrease is primarily due to higher gains from land sales in Minnesota during 2007.

Investment in ATC contributed income of $4.0 million in 2008 ($3.7 million in 2007).

Real Estate contributed income of $2.0 million in 2008 ($14.6 million in 2007). Income was lower in 2008 due to the continued weak real estate market and two large sales that closed in the second quarter of 2007.

Other contributed income of $3.6 million in 2008 ($2.9 million in 2007). The increase is primarily due to a $3.8 million after-tax gain realized from the sale of certain available for sale securities in the first quarter of 2008. The gain was triggered when securities were sold to reallocate investments to meet defined investment allocations based upon an approved investment strategy.

COMPARISON OF THE QUARTERS ENDED JUNE 30, 2008 AND 2007

(See Note 2 - Business Segments for financial results by segment.)

Regulated Utility

Operating revenue decreased $15.5 million, or 9 percent, from 2007, primarily due to decreased fuel clause recoveries and the reduction in revenue from sales to Other Power Suppliers. The decrease was partially offset by higher revenues attributable to current cost recovery on our environmental retrofit projects, new FERC approved wholesale rates, an approximately 2 percent increase in retail and municipal kilowatt-hour sales, and increased gas sales.

Fuel clause recoveries decreased $22.9 million in 2008 primarily as a result of decreased purchased power expenses reflecting increased Company generation and increased hydro availability (see Fuel and Purchased Power Expense discussion below).

Revenue from sales to Other Power Suppliers decreased $7.6 million from 2007 due to the expiration of sales contracts.

Increased revenues attributable to current cost recovery on our environmental retrofit projects totaled $4.8 million.

New FERC approved wholesale rates, effective March 1, 2008, resulted in an additional $2.1 million of operating revenue.

Kilowatt-hour sales to our retail and municipal customers increased 2 percent from 2007, primarily due to a 3.2 percent increase in industrial load. The increase in industrial sales in 2008 primarily reflects increased sales to one taconite customer that was partially idled in 2007. Total regulated utility kilowatt-hour sales were down 3.0 percent as the expiration of sales contracts to Other Power Suppliers more than offset the increased retail and municipal sales.

Gas sales increased $1.7 million, or 44 percent, over 2007 reflecting a colder 2008.

COMPARISON OF THE QUARTERS ENDED JUNE 30, 2008 AND 2007 (Continued)
Operating revenue (Continued)

Revenue from electric sales to taconite customers accounted for 27 percent of consolidated operating revenue in 2008 (24 percent in 2007). Revenue from electric sales to paper and pulp mills accounted for 9 percent of consolidated operating revenue in 2008 and 2007. Revenue from electric sales to pipelines and other industrials accounted for 7 percent of consolidated operating revenue in 2008 and 2007.

Operating expenses decreased $14.7 million from 2007.

Fuel and Purchased Power Expense decreased $17.9 million, or 19 percent, from 2007, primarily due to a decrease in purchase power expense reflecting increased Company generation and increased hydro availability. In 2007, scheduled outages at Boswell Unit 3 and Taconite Harbor Unit 2 as well as generator repairs at Boswell Unit 4 drove the higher purchased power expense.

Operating and Maintenance Expense increased $2.2 million, or 4 percent, from 2007 due to increased gas purchases, reflecting a colder 2008; and higher salaries and wages, reflecting annual inflationary increases.

Depreciation Expense increased $1.0 million from 2007 reflecting higher property, plant and equipment balances as a result of increased construction activity.

Interest Expense increased $0.4 million, or 8 percent, from 2007 primarily due to higher long term debt balances from increased construction activity.

Other income increased $0.2 million from 2007 due to higher earnings from the capitalization of AFUDC-Equity reflecting increased construction activity.

Nonregulated Energy Operations

Operating revenue increased $2.1 million, or 13 percent, from 2007 primarily due to higher coal prices at BNI Coal.

Operating expenses increased $1.4 million, or 9 percent, from 2007 primarily due to higher fuel expense and dragline repairs at BNI Coal.

Investment in ATC

Equity Earnings increased $0.4 million, or 13 percent, from 2007 resulting from our pro-rata share of ATC's earnings on an increased investment balance as discussed in Note 3.

Real Estate

Operating revenue decreased $20.1 million from 2007. Revenue from land sales was $2.6 million in 2008 and did not include any previously deferred revenue. In 2007, revenue from land sales was $25.2 million, which included $1.0 million in previously deferred revenue and reflected two large sales that closed during the second quarter of 2007. Operating revenue in 2008 also included the pre-tax gain of $4.5 million resulting from the sale of the retail shopping center in Winter Haven, Florida on May 1, 2008.

There were no sales at Town Center or Palm Coast Park for the quarter ended June 30, 2008. For the quarter ended June 30, 2007, 435,000 non-residential square feet were sold at Town Center and 40,000 non-residential square feet were sold at Palm Coast Park. Town Center sold 130 residential units and Palm Coast Park sold 406 residential units. For the quarter ended June 30, 2008, 49 acres of Other Land was sold (no acres sold in 2007).

Operating expenses decreased $4.3 million, or 53 percent, from 2007 reflecting a decrease in the cost of real estate sold and decreased selling expenses.

COMPARISON OF THE QUARTERS ENDED JUNE 30, 2008 AND 2007 (Continued)

Other

Other income decreased $2.0 million from 2007 primarily due to lower earnings on cash and short-term investments of $0.8 million primarily due to lower average cash balances and the 2007 release from a loan guarantee for Northwest Airlines Corporation of $1.0 million.

Income Taxes

For the quarter ended June 30, 2008, the effective tax rate on income before minority interest and income taxes was 36.5 percent (31.9 percent for the quarter ended June 30, 2007). The effective tax rate was lower in 2007 primarily due to a state income tax audit settlement ($1.5 million effect). The effective rate of 36.5 percent for the quarter ended June 30, 2008, deviated from the statutory rate (approximately 40 percent) primarily due to deductions for Medicare health subsidies, AFUDC-Equity, investment tax credits, wind production tax credits and depletion.

COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2008 AND 2007

Regulated Utility

Operating revenue decreased $2.4 million from 2007, primarily due to decreased fuel clause recoveries and the reduction in revenue from sales to Other Power Suppliers. The decrease was partially offset by higher revenue attributable to current cost recovery on our environmental retrofit projects; an approximate 4 percent increase in retail and municipal kilowatt-hour sales, higher gas sales and new FERC approved wholesale rates.

Fuel clause recoveries decreased $15.0 million in 2008 primarily as a result of decreased purchased power expenses reflecting increased Company generation and increased hydro availability (see Fuel and Purchased Power Expense discussion below).

Revenue from sales to Other Power Suppliers decreased $13.2 million from 2007 due to the expiration of sales contracts.

Increased revenues attributable to current cost recovery on our environmental retrofit projects totaled $10.1 million.

Kilowatt-hour sales to our retail and municipal customers increased approximately 4 percent from 2007, primarily due to a 5.0 percent increase in industrial sales. The increase in industrial sales in 2008 primarily reflects increased sales to one taconite customer that was partially idled in 2007 and another customer that was shut down due to weather related issues in 2007. Total regulated utility kilowatt-hour sales are down 1.0 percent as the expiration of sales contracts to Other Power Supplier contracts more than offset the increased retail and municipal sales.

Gas sales increased $3.6 million, or 27 percent, over 2007 reflecting a colder 2008.

New FERC approved wholesale rates, effective March 1, 2008, resulted in an additional $2.3 million of operating revenue.

Revenue from electric sales to taconite customers accounted for 26 percent of consolidated operating revenue in 2008 (23 percent in 2007). Revenue from electric sales to paper and pulp mills accounted for 10 percent of consolidated operating revenue in 2008 (9 percent in 2007). Revenue from electric sales to pipelines and other industrials accounted for 7 percent of consolidated operating revenue in 2008 and 2007.

Operating expenses increased $0.3 million from 2007.

Fuel and Purchased Power Expense decreased $9.3 million, or 5 percent, from 2007, due to a decrease in purchase power expense reflecting increased Company generation and increased hydro availability. In 2007, scheduled outages for the AREA plan and Boswell Unit 3 environmental upgrades as well as generator repairs at Boswell Unit 4 drove the higher purchased power.

COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2008 AND 2007 (Continued)
Operating Expenses (Continued)

Operating and Maintenance Expense increased $7.7 million, or 7 percent, over 2007 due to increased gas purchases reflecting a colder 2008, higher salaries and wages and transmission expense.

Depreciation Expense increased $1.9 million from 2007 reflecting higher property, plant, and equipment balances as a result of increased construction activity.

Interest Expense increased $1.0 million, or 10 percent, from 2007 primarily due to higher long term debt balances from increased construction activity.

Other income increased $0.8 million from 2007 due to higher earnings from the capitalization of AFUDC-Equity reflecting increased construction activity.

Nonregulated Energy Operations

Operating revenue increased $2.6 million, or 8 percent, from 2007, primarily due to higher coal prices at BNI Coal.

Operating expenses increased $2.6 million, or 8 percent, from 2007 primarily due to higher fuel expense and dragline repairs at BNI Coal.

Other income decreased $2.0 million from 2007 due to higher gains from land sales in Minnesota during 2007.

Investment in ATC

Equity Earnings increased $0.9 million, or 15 percent, from 2007 resulting from our pro-rata share of ATC's earnings on an increased investment balance as discussed in Note 3.

Real Estate

Operating revenue decreased $25.6 million from 2007. Revenue from land sales was $3.9 million in 2008 and did not include any previously deferred revenue. In 2007, revenue from land sales was $32.5 million, which included $2.3 million in previously deferred revenue and reflected two large sales that closed during the second quarter of 2007. Operating revenue in 2008 also included the pre-tax gain of $4.5 million resulting from the sale of the retail shopping center in Winter Haven, Florida on May 1, 2008.

There were no sales at Town Center or Palm Coast Park for the six months ended June 30, 2008. Through June 30, 2007, 435,000 non-residential square feet were sold at Town Center and 40,000 non-residential square feet were sold at Palm Coast Park. Town Center sold 130 residential units and Palm Coast Park sold 406 residential units. For the six months ended June 30, 2008, 51 acres of Other Land was sold (367 acres in 2007).

Operating expenses decreased $3.8 million, or 34 percent, from 2007 reflecting a decrease in the cost of real estate sold and decreased selling expenses.

Other

Operating expenses increased $0.4 million from 2007 as a result of additional expense related to our Georgia Water dispute as discussed in Note 11.

Other income increased $3.6 million from 2007 primarily due to a $4.0 million after-tax gain realized from the sale of certain available for sale securities in the first quarter. The gain was triggered when securities were sold to reallocate investments to meet defined investment allocations based upon an approved investment strategy. The increase was partially offset by lower earnings on cash and short-term investments reflecting lower average cash balances and a lower average interest rate, and the 2007 release from a loan guarantee for Northwest Airlines Corporation of $1.0 million.

COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2008 AND 2007 (Continued)

Income Taxes

For the six months ended June 30, 2008, the effective tax rate on income before minority interest and income taxes was 36.6 percent (35.1 percent for six months ended June 30, 2007). The effective tax rate was lower in 2007 primarily due to a state income tax audit settlement ($1.5 million effect). The effective rate of 36.6 percent for the six months ended June 30, 2008, deviated from the statutory rate (approximately 40 percent) primarily due to deductions for Medicare health subsidies, AFUDC-Equity, investment tax credits, wind production tax credits and depletion.

CRITICAL ACCOUNTING ESTIMATES

Certain accounting measurements under applicable GAAP involve management's judgment about subjective factors and estimates, the effects of which are inherently uncertain. Accounting measurements that we believe are most critical to our reported results of operations and financial condition include: real estate revenue and expense recognition, pension and postretirement health and life actuarial assumptions, regulatory accounting, the valuation of investments and taxation. These policies are reviewed with the Audit Committee of our Board of Directors on a regular basis and summarized in Part II, Item 7 of our 2007 Form 10-K.

OUTLOOK

Earnings Guidance. ALLETE reaffirms its previously stated earnings guidance of a range from $2.70 to $2.90 per share for 2008. This earnings projection does not include an impact from any investment we may make in new growth opportunities.

Energy. As part of our strategy, we will leverage the strengths of our Regulated Utility business to improve our strategic and financial outlook and seek growth opportunities in close proximity to existing operations in the Midwest. We believe electric industry deregulation is unlikely in Minnesota and Wisconsin in the next five years.

Minnesota Power expects significant rate base growth over the next several years as it makes capital expenditures to comply with renewable energy requirements and environmental mandates. In addition, significant investment will be made in our existing low-cost generation fleet to provide for continued future operations as we continue to believe ownership of low-cost generation is a competitive advantage. Minnesota Power will also look for transmission opportunities which strengthen and enhance the regional transmission grid and take advantage of our geographic location between sources of renewable energy and growing energy markets. Our capital investments will be recovered through a combination of current cost recovery riders and anticipated increased base electric rates. We also expect kilowatt-hour growth due to the potential for up to 400 MW of additional growth from several new industrial customers planning projects in our service territory.

Our energy strategy is to be a leader in the movement toward renewable energy and cleaner power plants. We believe we can meet our customers' electric energy needs for the next decade while achieving real reductions in total carbon emissions. We are aggressively pursuing our renewable energy resources and expect to comply with Minnesota's renewable energy requirements prior to the 2025 deadline.

Renewable Generation Sources. The areas in which we operate have strong wind, water and biomass resources, and provide us with opportunities to develop a number of renewable forms of generation. Our electric service area in northeastern Minnesota is well situated for delivery of renewable energy that is generated here and in adjoining regions. We intend to secure the most cost competitive and geographically advantageous renewable energy resources available. We believe that the demand for these resources is likely to grow, and the costs of the resources to generate renewable energy will continue to escalate. While we intend to maintain our disciplined approach to developing generation assets, we also believe that by acting sooner rather than later we can deliver lower cost power to our customers and maintain or improve our cost competitiveness among regional utilities. We will continue to work cooperatively with our customers, our regulators and the communities we serve to develop generation options that reflect the needs of our customers as well as the environment. We believe that our location and our proactive leadership in developing renewable generation provide us with a competitive advantage. For more than a century, we have been Minnesota's leading producer of renewable hydroelectric energy.

OUTLOOK (Continued)
Energy (Continued)

We have already begun executing our renewable energy and cleaner power plant strategy. Taconite Ridge Wind I, a $50 million, 25-MW wind facility located in northeastern Minnesota became operational in July 2008. Costs related to the construction of this facility have been included in our May 2, 2008 rate filing.

On May 13, 2008, we announced plans to develop several hundred megawatts of wind energy in North Dakota and purchase an existing 250 kV DC transmission line to transport this wind energy to customers while gradually reducing the supply of energy currently delivered to our system on this same transmission line from Square Butte's coal-fired Milton R. Young Unit 2. The North Dakota wind project is expected to meet our mandated renewable energy supply requirements for our retail load. We anticipate signing definitive agreements and making the required regulatory filings for the project in the third quarter of 2008. Closing on the purchase of the transmission line is expected in the first quarter of 2009.

Integrated Resource Plan (IRP). On October 31, 2007, we filed our IRP, a comprehensive estimate of future capacity needs within the Minnesota Power service territory. On July 25, 2008, we filed a request with the MPUC for approval to re-file our IRP by October 1, 2009, in order to incorporate the North Dakota wind project and otherwise update our load forecasting and modeling in the IRP.

Climate Change. A key component of our energy strategy is a goal to reduce overall GHG emissions. While there continues to be debate about the causes and extent of global warming, certain scientific evidence suggests that emissions from fossil fuel generation facilities are a contributing factor. Minnesota Power has a long history of environmental stewardship.

We believe that future regulations may restrict the emissions of GHGs from our generation facilities. Several proposals on the federal level to "cap" the amount of GHG emissions have been made. Other proposals consider establishing emissions allowances or taxes as economic incentives to address the GHG emission issue.

In 2007, Minnesota passed legislation establishing non-binding targets for GHG reductions. This legislation establishes a goal of reducing statewide GHG emissions across all sectors producing those emissions to a level at least 15 percent below 2005 levels by 2015, at least 30 percent below 2005 levels by 2025, and at least 80 percent below 2005 levels by 2050. Minnesota is also participating in the Midwestern Greenhouse Gas Accord, a regional effort to develop a multi-state approach to GHG emission reductions. We are proactively taking steps to strategically engage the GHG emission issue and the impact of climate change regulation on our business.

Minnesota Power is addressing this challenge by taking the following steps that also ensure reliable and environmentally compliant generation resources to meet our customer's requirements:

· We will consider only carbon minimizing resources to supply power to our customers. We will not consider a new coal resource without a carbon emission solution.

· We will aggressively pursue Minnesota's Renewable Energy Standard by adding significant renewable resources to our portfolio of generation facilities and power supply agreements.

· We will continue to improve the efficiency of coal-based generation facilities.

· We plan to implement aggressive demand side conservation efforts.

· We will continue to support research of technologies to reduce carbon emissions from generation facilities and support carbon sequestration efforts.

· We plan to achieve overall carbon emission reductions while maintaining competitively priced electric service to our customers.
