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.

Tampa Electric Initiates Regulatory Approval Process for IGCC Plant in Florida
LCG, July 23, 2007--Tampa Electric, the principal subsidiary of TECO Energy, filed on July 20 an application with the Florida Public Service Commission (FPSC) to demonstrate the need to construct the proposed 632-MW Polk Unit 6, a coal-fired power plant. The proposed new unit would employ an advanced, Integrated Gasification Combined Cycle (IGCC) design. Tampa Electric plans to commence operations at the proposed plant by 2013.
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 gasification plant will be designed to gasify both biomass and coal. Tampa Electric was the country's first utility to commercialize IGCC technology in partnership with the Department of Energy's (DOE) clean coal technology program by developing Polk 1 in 1996.
The proposed new unit is to be build at the existing Polk Power Station in Polk County, Florida.
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.
The new generating capacity would be used to serve the growing demand for electricity in Florida and to maintain reliability.
Tampa Electric filed the application at a time when coal is not king in Florida. Florida Governor Charlie Crist recently raised concerns regarding the threat of climate change and the use of fossil fuels. In June, the FPSC reached a decision to not approve the coal-fired plant proposed by Florida Power and Light in Glades County. Furthermore, a group of community-owned, power entities (Florida Municipal Power Agency (FMPA), JEA, Reedy Creek Improvement District, and the City of Tallahassee) have decided to suspend permitting activities for the Taylor Energy Center, an 800-MW, coal-fired power plant proposed to be built in Taylor County, Florida.
