Delmarva Power announced Tuesday that it will buy the power produced by the 38-megawatt Chestnut Flats wind farm in Blair County, Pa., near Altoona.

Delmarva had originally agreed to buy power from a western Maryland wind farm built by Synergics Eastern Wind Energy L.L.C., which environmentalists have opposed because it allegedly threatens an endangered bat species.

Synergics instead will supply Delmarva from the Pennsylvania facility, which was developed by Gamesa Technology Corp. using turbines manufactured at its plant in Fairless Hills, Bucks County.    - Andrew Maykuth
