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.

DOE Clears the Path to Build Coal Plant Employing IGCC Technology
LCG, April 3, 2007--The Department of Energy (DOE) announced today that it has executed a Record of Decision that, according to the DOE statement, "clears the path for construction of a $569-million, 285-megawatt coal-fired power plant that will be one of the cleanest, most efficient plants of its kind in the world." The new plant will be built near Orlando, Florida at the existing Stanton Energy Center that is owned by the Orlando Utilities Commission (OUC).
The new coal plant will employ an integrated gasification-combined cycle (IGCC) technology based on the transport gasifier that Southern Company and others have been developing at the Power Systems Development Facility near Wilsonville, Alabama. The transport gasifier offers a simpler method to generate power from coal and is cost-effective when handling low rank coal, as well as coals with high moisture or high ash content. The DOE will provide a $235 million federal grant for the development of the advanced coal plant.
The new facility will be co-owned by Southern Power Company (the unregulated subsidiary of Southern Company), OUC, and Kellogg, Brown and Root. Operations of the new facility had been planned previously announced to commence in 2010.
The project is one of three, demonstration projects receiving funding through the federal Clean Coal Power Initiative (CCPI), a 10-year, $2-billion demonstration program designed to improve the environmental performance of coal-fired power plants in the United States. The other two projects are Excelsior Energy Inc. and ConocoPhillips? 531-MW Mesaba Energy Project in Minnesota, and the Pegasus Technology Project, which combines Pegasus Technologies Inc. with Texas Genco to demonstrate technology advancements to reduce emissions.
Southern Company's wholly owned utility, Mississippi Power Company, is also developing an advanced coal plant. Last December, plans were announced to build a 600-MW power plant fueled by lignite in Kemper County, Mississippi that would use an advanced gasification technology developed by Southern Company. The estimated cost of the facility is approximately $1.8 billion. The project is to receive over $133 million in tax credits from the DOE as a result of the National Energy Policy Act of 2005. The Mississippi plant is scheduled to commence operations in June 2013.
