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.

LCG, September 4, 2025--Puget Sound Energy (PSE) announced yesterday that phased construction has commenced on its 142-MW Appaloosa Solar Project, a utility-scale solar facility underway in southeastern Washington. The project is being built by Qcells EPC, who will serve as the module manufacturer and the engineering, procurement, and construction (EPC) solution provider. Construction is scheduled through 2026, and commercial operation is expected at the end of next year.

Construction Underway of IGCC Coal Plant in Florida
LCG, September 12, 2007--Southern Company announced yesterday that construction is now underway of an advanced, coal-fired power plant employing integrated gasification combined cycle (IGCC) technology. The new plant is near Orlando, Florida at the existing Stanton Energy Center that is owned by the Orlando Utilities Commission (OUC). The IGCC plant is co-owned by Southern Power Company (the unregulated subsidiary of Southern Company), OUC, and Kellogg, Brown and Root.
Southern Power will operate the plant, and commercial operation is scheduled for June 2010.
The facility will use an IGCC technology based on the Transport Integrated Gasification (TRIG) technology that Southern Company and others have been developing at the Power Systems Development Facility near Wilsonville, Alabama. The IGCC process converts coal into a synthesis gas and minimizes most of the sulfur dioxide (SO2), nitrogen oxides (NOx), mercury (Hg) and other emissions before the gas fuels a combustion turbine generator. The hot exhaust gas from the turbine heats water to produce steam to power a steam turbine and generate electricity a second time. 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 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 Department of Energy (DOE) will provide a $235 million federal grant for the development of the advanced coal plant.
Tampa Electric, the principal subsidiary of TECO Energy, has also proposed building a coal-fired, IGCC facility in Florida. In July, Tampa Electric filed an application with the Florida Public Service Commission (FPSC) to demonstrate the need to construct Polk Unit 6, a 632-MW unit using an IGCC design. The proposed new unit is to be build at the existing Polk Power Station in Polk County, Florida. Tampa Electric plans to commence operations at the proposed plant by 2013.
Tampa Electric estimates the capital cost to be approximately $2 billion, which includes $1.6 billion for engineering, procurement and construction, plus $400 million in additional related costs, such as transmission infrastructure, environmental permitting, project management, staffing and training, and contingency costs.
Tampa Electric was the country's first utility to commercialize IGCC technology in partnership with the DOE's clean coal technology program by developing Polk 1 in 1996.
