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.

TVA Sued for Smoking Up the Great Smokies
LCG, Oct. 4, 2000The National Parks Conservation Association has filed a lawsuit against the Tennessee Valley Authority, charging that the taxpayer-owned electric utility is making the Great Smoky Mountains National Park smokier than it ought to be, the Environmental News Service reported yesterday.In a lawsuit filed in Federal District Court in Knoxville, Tenn., the conservation association says TVA has exceeded Clean Air Act limits for opacity, a measurement of the density of smokestack pollutants, at its 1,400 Kingston and 712 megawatt John Sevier power plants.Kingston burns about 3.8 million tons of coal per year and John Sevier more than two million tons, ENS said. And they are not even TVA's dirtiest coal-burners. The federal agency's Chattanooga plant puts out more oxides of nitrogen than any other U.S. industrial facility while its Cumberland City facility leads the way in emitting sulphur dioxide.No one is quite sure how TVA, which was created in the 1930s to harness the Tennessee River, got into coal-fired power plants or nuclear plants, for that matter. The lawsuit seeks a court order requiring TVA to comply with established air pollution emission limits, ENS said, and to pay civil penalties to the federal government for opacity violations for the past five years."People like to think of the Smokies as a pristine natural environment," said Tom Kiernan, NPCA president. "In fact, it's among the most polluted national parks in America. TVA is a federal agency and a major source of that air pollution, and we want the agency to do much, much more to protect the park."
