PUC of Texas Approves Entergy Texas' Plans to Build Over 1,200 MW of Gas-Fired Capacity

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.

Growing Competition for New Nuclear Reactor Designs

LCG, September 16, 2005--Constellation Energy and AREVA Inc. announced yesterday that they formed a joint venture, UniStar Nuclear, to develop and sell new nuclear power plants in the United States. The plants will be based upon AREVA's 1,600-MW European pressurized water reactor (EPR) that is currently being deployed in Europe. Bechtel Power Corporation will support the venture with its expertise as an architect-engineer and constructor.

Unistar Nuclear will provide the platform to develop joint ventures, and AREVA will be the prime contractor, providing the nuclear reactor and all support systems, instrumentation and control system and initial load of nuclear fuel. Constellation Energy, through new joint ventures, would license, construct, own and operate the new nuclear power plants based upon AREVA's EPR design.

The EPR design is used in one reactor currently under construction in Finland and is used in another reactor to be built in France. The companies stated that over 200 engineers are now working in support of obtaining a design certification for the U.S. Evolutionary Power Reactor (US EPR) as a standard plant from the United States Nuclear Regulatory Commission (NRC). The companies expect that new plants will be ready to begin production in 2015.

The announcement of the new venture adds to the growing competition associated with the development of new nuclear reactors. On August 31, GE Energy submitted its Design Certification application to the NRC for its economic simplified boiling water reactor (ESBWR). GE anticipates the Final Design Approval toward the end of 2006 and that it will receive Design Certification immediately thereafter. The ESBWR is a 1,500-MW design that incorporates passive safety features that rely upon natural forces, such as gravity, in order to reduce reliance on active, mechanical systems, like pumps and valves.

Another primary reactor design for consideration in the United States is offered by Westinghouse Electric. A year ago, the NRC granted a Final Design Approval to Westinghouse for its AP1000 advanced reactor design.
