PUC of Texas Approves Entergy Texas' Plans to Build Over 1,200 MW of Gas-Fired Capacity

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.

Duke's IGCC Project Clears Regulatory Hurdles

LCG, January 8, 2009--Duke Energy's proposed integrated gasification combined cycle (IGCC) project yesterday received favorable rulings from the Indiana Utility Regulatory Commission (IURC). The revised cost estimate of $2.35 billion, which reflects a $365 million dollar increase, was approved by the IURC, together with a proposed study regarding carbon emission capture and sequestration.

The coal-fired, IGCC project will be built at Duke's existing Edwardsport Generating Station near Vincennes, Indiana. Once the new, 630-MW power plant is operational, the old facilities, which include coal and oil units that have a capacity of 160-MW, will be retired. Construction on the project commenced last year and is scheduled for completion in 2012.

With the IGCC design, synthetic gas created from coal is used in a gas turbine to generate electricity. The hot exhaust gas from the turbine heats water to produce steam to power a steam turbine and generate electricity a second time. The gasification process offers the potential for lower cost solutions to capture and sequester CO2, which may assist in efforts to thwart global warming. Duke's study will explore capturing and storing carbon dioxide permanently in underground geologic formations.

Duke filed an application for a "Certificate of Public Convenience and Necessity" (CPCN) with the IURC to build the plant in September 2006. In November 2007, the IURC directed Duke to develop carbon capture and storage studies for the project, and Duke filed its plans in May 2008, together with the $365 million cost increase request.
