MONONGAHELA — FirstEnergy says it will close two coal-fired power plants in southwestern Pennsylvania as scheduled next week with no expectations they will be sold or reopened under stricter environmental regulations.

“Those plants are losing money today and will lose money in the future. Our plans are not to run those units again,” company president James Lash told state lawmakers at a Thursday hearing.

Lash said no potential buyers have come forward for the 370-megawatt Mitchell Power Station in Washington County or the 1,710-megawqatt Hatfield’s Ferry Power Station in Greene County. He said the company has made job offers to 140 of 175 union workers affected.

Members of the House Consumer Affairs Committee are considering testimony on the effects of the closures on the region’s electric grid.

Valley Forge-based PJM Interconnection, which distributes electricity to Pennsylvania and 12 other states, said last month it saw “no system reliability problems” stemming from the planned Friday deactivation.

Pamela Witmer, a member of the state Public Utility Commission, testified that although FirstEnergy gave the 90 days required to review the reliability of service, she still worried that PJM might not have had enough time to assess the effects of losing 2,000 megawatts of power, which help supply 1.5 million Pennsylvania homes each year.
