LCG, November 26, 2025--RWE announced today the commissioning of the Stoneridge Solar project, located in Milam County, Texas. The project capacity is 200 MW of solar power, plus a battery energy storage system (BESS) that provides 100 MW (200 MWh) of battery storage capacity. The BESS improves the supply of short-term, reliable, affordable electricity in ERCOT.

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

NRG Backs Out of Nuclear Expansion Project in Texas
LCG, April 20, 2011--NRG Energy, Inc. (NRG) yesterday announced that it will write down its investment in the development of South Texas Project (STP) units 3 and 4. Moreover, NRG stated that it will not invest additional funds in the STP development effort.
Last month the United States Nuclear Regulatory Commission (NRC) issued a favorable final environmental impact statement (EIS) for building the two, 1,350-MW Advanced Boiling Water Reactors (ABWRs) at the South Texas Project, an existing nuclear station located approximately 90 miles southwest of Houston. Nuclear Innovation North America (NINA), a partnership between NRG and Toshiba Corp., applied for the permits in late 2007. NINA had planned to receive a construction license next year and commence operations of the two units in 2016 and 2017, respectively.
NRG's backing out of the STP project is driven by the recent events in Japan. NRG's President and CEO stated, "The tragic nuclear incident in Japan has introduced multiple uncertainties around new nuclear development in the United States which have had the effect of dramatically reducing the probability that STP 3 and 4 can be successfully developed in a timely fashion. We continue to believe both in the absolute necessity of a U.S. nuclear renaissance and that STP 3 and 4 is the best new nuclear development project in the country bar none. However, the extraordinary challenges facing U.S. nuclear development in the present circumstance and the very considerable financial resources expended by NRG on the project over the past five years make it impossible for us to justify to our shareholders any further financial participation in the development of the STP project."
NRG stated that NINA has suspended indefinitely all detailed engineering work and other pre-construction activities and will be focused solely on securing (i) a combined operating license (COL) from the NRC and (ii) a loan guarantee from the U.S. Department of Energy (DOE).
The South Texas Project Nuclear Operating Company currently operates units 1 and 2, which are 1,410-MW pressurized water reactors that commenced operations in the late 1980s. STP ownership is divided among NRG at 44 percent, San Antonio municipal utility CPS Energy at 40 percent, and Austin Energy at 16 percent.
