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.

Dominion Energy Virginia Receives Approval for Nearly 500 MW of New Solar Capacity
LCG, May 4, 2021--The Virginia State Corporation Commission (SCC) approved last Friday the largest group of new solar projects for Dominion Energy Virginia customers. The nine new solar facilities will total nearly 500 MW of generating capacity and represent a major step toward achieving the goals of the Virginia Clean Economy Act (VCEA) and Dominion Energy's goal of net zero emissions.
The president of Dominion Energy Virginia stated, "This is another major step forward in building a clean energy economy in Virginia. Our customers deserve reliable and affordable energy, and they also deserve a clean environment. These projects will help us deliver on that promise."
Six of the nine new solar projects are PPAs that were selected following a competitive solicitation process. Dominion Energy owns and will operate the other three projects: Grassfield Solar, a 20-MW facility in the City of Chesapeake; Norge Solar, a 20-MW facility in James City County; and Sycamore Solar, a 42-MW facility in Pittsylvania County.
Dominion Energy plans to submit this fall its annual filing to the SCC requesting approval to construct or purchase another large group of solar, wind and energy storage projects. The company will issue Requests for Proposals (RFPs) from developers to support these filings.
The VCEA was signed into law in April 2020 and established renewable portfolio standards (RPS) for Virginia that include requiring Dominion Energy Virginia to be 100 percent carbon-free by 2045 and Appalachian Power to be 100 percent carbon-free by 2050. Furthermore, the VCEA requires nearly all coal-fired plants to close by the end of 2024.
The renewable requirements in the Act established that 16,100 MW of solar and onshore wind is "in the public interest" and requires Virginia's largest energy companies to install or acquire more than 3,100 MW of energy storage capacity by 2035. Furthermore, the VCEA provides that, prior to the end of 2034, up to 5,200 MW of offshore wind generation is "in the public interest."
In any application before the SCC to construct a new generating facility, the utility must include the social cost of carbon, as determined by the Commission, and the Commission may adopt any rules it deems necessary to determine the social cost of carbon.
