Page 16. - Item 2 Properties - Electric Operations Ref. Page 25. - Outlook - Electric Operations - Eighth Paragraph On June 22, 1999 Minnesota Power announced plans to build a natural gas-fired power plant near the city of Superior, Wisconsin. The combustion turbine power generating station will be capable of producing approximately 90 megawatts of electric power and cost approximately $35 million to $40 million to build. Pending any regulatory approvals, construction of the plant would begin during the year 2000 with completion scheduled in 2002. Combustion turbines produce low emissions, making them an environmentally advantageous way to generate electricity. The plant will help alleviate a developing shortage of electricity during periods of peak electrical demand during summer and winter months, thereby improving the dependability of the electric system for the Company's customers. This facility will also help the Company avoid purchasing higher cost power when other Company generating facilities are down for maintenance. Ref.
