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.

Salt River Project Efforts to Restart Mohave Generating Station Stall
LCG, February 8, 2007--The Salt River Project (SRP) announced Tuesday that it has concluded that it will be unable to upgrade and restart the coal-fired Mohave Generating Station near Laughlin, Nevada. Negotiations with Southern California Edison, the majority owner and operator of the facility have ceased. SRP stated that it was unable to adequately address its need for timely regulatory approvals to restart the plant by 2011.
The Mohave Generating Station, with an electric generating capacity of 1,580-MW, was closed at the end of 2005, when the 35-year operating permit expired. To reopen the plant, investments expected to cost $1.1 billion are necessary for a variety of improvements, including the installation of pollution control equipment required under a 1999 consent decree. Other issues include obtaining water supplies from the Hopi and Navajo tribes.
The current owners of the facility are Southern California Edison (SCE), SRP, Nevada Power Company, and the Los Angeles Department of Water and Power (LADWP), and their respective ownership percentages are: 56, 20, 14 and 10 percent. In June 2006 SCE, Nevada Power Company and LADWP all stated that they would not participate in reopening the power plant. SRP then announced in September that it was seeking new partners to rebuild the facility and that it planned to have a final environmental impact statement by the summer of 2007.
The State of California's position to reduce carbon emissions and limit the use of electricity generated by coal-fired plants is clearly at odds with the California utilities importing power from the Mohave Generating Station. SCE stated that it would continue to explore options, including the sale or decommissioning of the facility.
