360-MW millennium power plant achieves commercial operation status

BETHESDA, Md., April 12, 2001 — PG&E National Energy Group, an affiliate of PG&E Corporation today announced that its 360-megawatt Millennium Power plant in Charlton, Massachusetts achieved commercial operation.

“The achievement of commercial operation is a significant milestone for the Millennium project and the community,” said Mark Winne, plant general manager. “The gas and steam turbines used at Millennium are the latest in combined-cycle combustion technology,” Winne said.

The plant is fueled with natural gas transported by Tennessee Gas Pipeline Company and has the ability to generate enough power to meet the needs of approximately 360,000 homes. Its power will be sold into the competitive New England electric system.

Siemens Westinghouse Power Generation manufactured the 501G-combustion turbine and steam turbine generator that comprise the power-island of the facility.

The National Energy Group has ownership or management interests in more than 7,000 megawatts and more than 10,000 megawatts in new power plant development or construction currently under way.

Its pipeline system in the Pacific Northwest has the ability to transport 2.7 billion cubic feet of natural gas a day. The National Energy Group’s power and gas trading operation is one of the fastest growing in the nation with a 2000 trading volume of 283 million megawatt-hours of power and 6.5 billion cubic feet per day of natural gas.
