LCG, Dec. 12, 2000--Constellation Energy Group and Niagara Mohawk Power Corp. said separately this morning that Constellation will purchase Unit 1 and 82 percent of Unit 2 of the Nine Mile Point nuclear power plant in a deal valued at about $1.04 billion.

Niagara Mohawk said the sellers will realize $815 million in cash, $134 million in interest and $88 million in decommissioning savings.

Constellation will get 82 percent of the 1,148 megawatt Nine Mile Point Unit 2 from its owners, Niagara Mohawk, New York State Electric & Gas Co., Rochester Gas & Electric Co. and Central Hudson Gas & Electric Corp. The Long Island Power Authority, an 18 percent owner of Nine Mile 2, elected to hang onto its share of the unit.

Niagara Mohawk is the sole owner of the 609 megawatt Nine Mile Point Unit 1.

The terms of the deal include power purchase agreements under which Constellation will sell 90 percent of the output of the two reactors back to the sellers for about 10 years at an average price of around $35 per megawatt-hour.
