RWE Commissions the 200-MW Stoneridge Solar Project in Texas

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.

Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

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 Files with NRC to Construct New Nuclear Reactors in Texas

LCG, September 25, 2007--NRG Energy, Inc. (NRG) and South Texas Project Nuclear Operating Company (STPNOC) yesterday announced that they will file a Combined Construction and Operating License (COL) Application with the Nuclear Regulatory Commission (NRC) to construct and operate two new nuclear units at the South Texas Project, located about 90 miles southwest of Houston. NRG expects the new units to commence operations in 2014 and 2015.

The combined design capacity of the new units will equal or exceed 2,700 MW. The existing two units are pressurized water reactors, each with a capacity of 1,312 MW. NRG selected the Advanced Boiling Water Reactor (ABWR) technology for the new units. The NRC issued final design certification for the GE ABWR in 1997, allowing it to be used in U.S. projects. The ABWR is a "Generation III" reactor design that is in operation today, with four operating units in Japan and three more approaching completion in Taiwan and Japan.

STPNOC, together with a contracting team led by GE-Hitachi Nuclear Energy and Bechtel, prepared the COL application that was to be filed yesterday. The COL application includes two key components: a safety analysis and an environmental report. NRG anticipates that the NRC process will lead to NRG receiving its license approval such that it could commence construction in 2010.

The site and cooling reservoir were originally designed for four units, and the plans are for the new units to be built adjacent to the existing two units. STPNOC, which currently operates units 1 and 2, will operate the new units.

NRG owns 44 percent of the South Texas Project, and CPS Energy and Austin Energy own 40 percent and 16 percent, respectively. The nuclear expansion is part of NRG's corporate strategy to increase non-carbon emitting generation and reduce its carbon intensity.
