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.

EPA Proposes Carbon Standard to Limit New Coal-fired Power Generation
LCG, March 28, 2012--The U.S. Environmental Protection Agency (EPA) yesterday proposed the first Clean Air Act standard for carbon pollution from new power plants. The EPA stated that the rule creates a path forward for new technologies to be deployed at future facilities that will allow companies to burn coal, while emitting less carbon pollution.
The EPA stated that the rulemaking proposed only concerns future generating units and does not apply to existing units or units that will start construction over the next 12 months.
The EPA's new rules for new power plants will apply to all fossil fuel generators greater than 25 MW and will limit carbon dioxide emissions to 1,000 pounds per megawatt hour generated. With that limit, new coal-fired facilities will need to capture and sequester a portion of emissions. Current carbon capture technologies are not readily available on a commercial scale and are expensive.
EPA Administrator Lisa P. Jackson said, "Right now there are no limits to the amount of carbon pollution that future power plants will be able to put into our skies ? and the health and economic threats of a changing climate continue to grow. We?re putting in place a standard that relies on the use of clean, American made technology to tackle a challenge that we can?t leave to our kids and grandkids."
As a direct result of a Supreme Court ruling in 2007, EPA in 2009 determined that greenhouse gas pollution threatens Americans? health and welfare by leading to long lasting changes in our climate that can have a range of negative effects on human health and the environment.
The EPA stated that its proposed standards can be met by a range of power facilities burning different fossil fuels, including natural gas technologies, as well as coal with technologies to reduce carbon emissions. Even without today?s action, the EPA states that the power plants that power plants to be built in the future would already comply with the standard. Thus the EPA does not project an additional cost for industry to comply with this standard.
EPA's comment period for the rule will be open for 60 days following publication in the Federal Register.
