Allegheny Energy Supply, the unregulated generating subsidiary of Allegheny Energy Inc., has announced that it will build 88mw of natural gas-fired merchant generating capacity in Guilford Township, near Chambersburg, PA, USA. The new facility will help enhance the power supply of the Franklin County area, creating enough capacity to light up to 88,000 homes. Two 44mw General Electric LM6000 combustion turbines will be constructed near the village of Marion, PA. The equipment will be fired by natural gas and will operate primarily at times of peak electrical demand – typically on the hottest and coldest days of the year. Units are expected to be in commercial operation by the end of this year.
