State regulators gave the final go-ahead Tuesday to Old Dominion Electric Cooperative to start building a new $675 million power plant in Cecil County.

The new Wildcat Point Generation Facility, fueled by natural gas, will help Old Dominion meet the region's growing demand for electricity, CEO Jackson Reasor said. The plant, located next to the cooperative's existing property in Conowingo, is expected to generate 1,000 megawatts of electricity each year, power for roughly 390,000 homes.

The Virginia-based non-profit, which serves 1.2 million households in Maryland, Virginia and Delaware, went to the Maryland Public Service Commission for approval of the plant last spring. The project is expected to create 600 construction jobs and employ about 30 people after it opens in 2017, according to the cooperative.
