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.

Arkansas Public Service Commission Appeals Court Decision on SWEPCO's Coal Project
LCG, July 9, 2009--The Arkansas Public Service Commission (APSC) yesterday petitioned the Arkansas Supreme Court to review a recent appellate court decision that would delay or stop further development of the proposed John W. Turk Jr. electric generating station, a 600-MW, coal-fired project in Hempstead County, Arkansas.
Local landowners appealed a November 2007 decision by the APSC to grant a Certificate of Environmental Compatibility and Public Need (CECPN) to Southwestern Electric Power Company (SWEPCO) to build the plant. The locals stated that the proposed coal-fired facility would harm the local environment. On June 24, 2009, the Arkansas Court of Appeals ruled in favor of local landowners that the APSC's review of SWEPCO's proposed coal-fired project and site selection was inadequate.
APSC officials stated that the procedure for SWEPCO's application is consistent with the process used since they received jurisdiction in 1973 to review and issue such permits. The official said that the process was ?fair? and ?allowed all parties to argue the issues.?
Last week SWEPCO requested the Arkansas Supreme Court review the appellate court's decision. According to a SWEPCO spokesperson, "The APSC approval was overturned because the court objected to the approval procedure and not because the judges objected to the Turk Plant. We believe the Turk Plant holds the best future for long-term reliability and affordable power for our customers."
The estimated cost of the ultra-supercritical, advanced coal project is $1.6 billion, and project construction and spending is advancing at a rapid pace. Construction on began late last year, after the air permit was received from the Arkansas Department of Environmental Quality in November 2008. According to a SWEPCO spokesperson, "Approximately $713 million has already been spent on plant construction, and a total of $1.3 billion has been committed. It would cost even more to stop construction and then restart it."
SWEPCO will continue construction for the time being.
SWEPCO also serves customers in Louisiana and Texas. In March 2008, the Louisiana Public Service Commission (LPSC) unanimously approved SWEPCO's request to build the plant, including a requirement for SWEPCO to prepare and submit a study that identifies potential, cost-effective energy efficiency and load management programs for SWEPCO's Louisiana customers. The Public Utility Commission of Texas approved the proposal in July 2008.
