LCG, September 12, 2025--Entergy announced yesterday that the Public Utility Commission of Texas (PUCT) approved Entergy Texas’ proposal to build two efficient natural gas-fired power plants to support the region’s rapid growth. The combined electric generating capacity of the two facilities, the Legend Power Station and the Lone Star Power Station, will add over 1,200 MW to the Southeast Texas power grid to support new customer demand, increase reliability and lower costs for all customers. Both facilities are scheduled to commence operations by mid-2028.

Back to the Drawing Board for Salem Harbor Plant
LCG, July 13, 2004--The Federal Energy Regulatory Commission (FERC) issued an order last week for PG&E National Energy Group Inc. - the bankrupt owner of the Salem Harbor Power Plant - to work with ISO New England and others to develop a better plan to address the $85 million environmental cleanup of the plant. The FERC did not approve the plans that would have Eastern Massachusetts electric customers pay environmental cleanup costs.If an agreement on a new plan that addresses the FERC's concerns is not delivered within 60 days, the FERC will order a full investigation to determine if the plan "may be unjust, unreasonable...or otherwise unlawful."The Salem Harbor power station includes three coal-fired generating units totaling 313 MW, plus 450 MW oil-burning unit. PG&E has requested ISO New England officials to shut down the plant, given its lack of funds to pay for the environmental cleanup costs. However, from a system reliability perspective, ISO New England sees the plant as needed to avoid blackouts. "The ISO is pleased that the FERC recognizes that a reliability operating agreement for Salem Harbor will be needed until power system conditions improve in the Greater Boston area," said Ellen Foley, a spokeswoman for ISO New England.Those interested in purchasing the plant from PG&E must address the uncertainties regarding who carries the $85 million cost for environmental clean-up, plus the potential impact of transmission upgrades that would effectively (a) increase the competition between Salem and other generating stations and (b) reduce its "reliability" value from ISO New England's perspective.
