Wisconsin Energy, NRG Abandon Power Plant Sale

LCG, Sept. 20, 2001--Wisconsin Energy Corp. said this morning that it and NRG Energy Inc. have jointly terminated an agreement by NRG to purchase two power plants owned by Wisconsin Energy in Connecticut. The companies cited regulatory uncertainty as the reason.

"We are disappointed that we have to terminate this agreement, but remain confident that we will be able to profitably sell these assets because of their importance to the New England electricity market, fuel flexibility and skilled workforce," said Richard A. Abdoo, chief executive of Wisconsin Energy. "In the meantime, we will continue to safely and reliably operate these plants."

Wisconsin Energy said it had anticipated the receipt of approximately $350 million in gross proceeds from the sale, adding that the plants have operated profitably and the company expects that the contribution to earnings prior to an ultimate sale will remain positive.

"As we have announced, we are focusing on our core competencies of electric generation and electric and gas distribution in our service territory, pump manufacturing, and continuing our announced strategic priority of focusing on Wisconsin's energy needs with our "power the future" program," Abdoo said. "We remain committed to selling these assets to monetize their value for the benefit of our shareholders."

The power plants, located in Bridgeport and New Haven, Conn., have a combined capacity of about 1,100 megawatts.
