SECURITIES AND EXCHANGE COMMISSION WASHINGTON, DC 20549 FORM 8-K CURRENT REPORT Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 DATE OF REPORT (DATE OF EARLIEST EVENT REPORTED) - MAY 17, 2001 ALLETE, Inc. A Minnesota Corporation Commission File No. 1-3548 IRS Employer Identification No. 41-0418150 30 West Superior Street Duluth, Minnesota 55802-2093 Telephone - (218) 279-5000

ITEM 5. OTHER EVENTS. Reference is made to the 2000 Form 10-K of ALLETE, Inc. (ALLETE) for background information on the following update. Ref. Page 26 - Third Full Paragraph On May 17, 2001 Minnesota Power, ALLETE's electric utility business, and Cleveland-Cliffs Inc. announced that they have submitted a bid to acquire all of the assets of LTV Steel Mining Company (LTV) in northeastern Minnesota. Under terms of the proposal, Minnesota Power would acquire the LTV electric generating facility at Taconite Harbor and non-mining property owned by LTV. Cleveland-Cliffs would acquire the taconite processing plant along with all of LTV's property that is related to the mining operations. The LTV electric generation facility is comprised of three 75 megawatt electric generating units, all of which burn sub-bituminous coal. The facility is already interconnected to Minnesota Power's transmission grid. Minnesota Power will use the electricity generated for regional system capacity and energy needs, and a portion of the power will be reserved for redevelopment at the former LTV site. Upgraded environmental monitoring and control equipment would be installed as needed, subject to Environmental Protection Agency requirements. The taconite mining operation was closed on January 5, 2001 after LTV initiated a Chapter 11 bankruptcy proceeding. LTV has solicited bids from interested parties and has indicated its intent to select a party during the week of May 21, 2001 to commence negotiation of an asset purchase agreement.

Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions or future events or performance (often, but not always, through the use of words or phrases such as "anticipates," "believes," "estimates," "expects," "intends," "plans," "predicts," "projects," "will likely result," "will continue" or similar expressions) are not statements of historical facts and may be forward-looking. Forward-looking statements involve estimates, assumptions and uncertainties and are qualified in their entirety by reference to, and are accompanied by, the following important factors, which are difficult to predict, contain uncertainties, are beyond the control of ALLETE and may cause actual results to differ materially from those contained in forward-looking statements: - prevailing governmental policies and regulatory actions, including those of the United States Congress, state legislatures, the Federal Energy Regulatory Commission, the Minnesota Public Utilities Commission, the Florida Public Service Commission, the North Carolina Utilities Commission, the Public Service Commission of Wisconsin and various county regulators, about allowed rates of return, industry and rate structure, acquisition and disposal of assets and facilities, operation and construction of plant facilities, recovery of purchased power and capital investments, and present or prospective wholesale and retail competition (including but not limited to transmission costs); - economic and geographic factors, including political and economic risks; - changes in and compliance with environmental and safety laws and policies; - weather conditions; - population growth rates and demographic patterns; - competition for retail and wholesale customers; - pricing and transportation of commodities; - market demand, including structural market changes; - changes in tax rates or policies or in rates of inflation; - changes in project costs; - unanticipated changes in operating expenses and capital expenditures; - capital market conditions; - competition for new energy development opportunities; and - legal and administrative proceedings (whether civil or criminal) and settlements that influence the business and profitability of ALLETE. Any forward-looking statement speaks only as of the date on which that statement is made, and ALLETE undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which that statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for management to predict all of those factors, nor can it assess the impact of each of those factors on the businesses of ALLETE or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement. 2 ALLETE Form 8-K dated May 18, 2001
