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.

California Legislators Pass Energy Bill that Could Improve Outlook for Diablo Canyon

LCG, July 1, 2022--The California State legislature passed legislation (AB-205) Wednesday that could enable the Diablo Canyon nuclear plant to continue operating and providing carbon-free power to support the electric reliability of the California grid. The nuclear plant may also be able to access federal funds from the Infrastructure Bill’s $6 billion Civil Nuclear Credit (CNC) Program that is designed to keep nuclear power plants with financial shortfalls online. The Governor is expected to sign the legislation.

Back in June 2016, PG&E announced a Joint Proposal with labor and environmental organizations that would increase investment in energy efficiency, renewables and storage beyond then-current state mandates while prematurely phasing out PG&E’s 2,240-MW Diablo Canyon Power Plant in lieu of operating under license extensions. (The reactors’ operating licenses expire in November 2024 for Unit 1 and August 2025 for Unit 2.)

The current legislation, AB-205, would establish the Strategic Reliability Reserve (SRR) to be administered by the California Department of Water Resources (DWR) to support electrical grid reliability. The bill authorizes DWR to contract for, purchase, finance or otherwise secure electrical generation to create additional capacity available during extreme energy grid events.

The bill would require DWR to prepare a plan for its actions to invest in electric reliability for the California Energy Commission (CEC) to consider and approve. Furthermore, the bill requires the DWR to consult with the CEC, California Public Utilities Commission (PUC) and the California Independent System Operator (CAISO) or other applicable balancing authorities, and the California Air Resources Board when carrying out the duties of SRR.

The bill could also support and accelerate new renewable power installations. The bill would authorize the CEC to permit the siting of facilities by the DWR in implementing SRR programs, and it would establish an expedited review of applications. This bill would require the CEC in reviewing permitting requests to determine optimal location for resources based on electric reliability, reducing public safety power shutoffs, decreasing the use of high-emission resources and minimizing air pollution.

The DWR also would be required to submit a report to the Joint Legislative Budget Committee starting on January 31, 2023, and in specified intervals, on expenditures related the program.
