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.

California ISO Declares a Stage 3 Alert – No Outages Yet
LCG, Jan. 16, 2001The California Independent System Operator, still struggling to come up with enough power to meet a forecast demand of 32,315 megawatts in its control area, declared a Stage 3 Electricity Emergency at 7:20 this morning, pacific time.The ISO said that a total of 10,700 megawatts of generation was off line because of planned maintenance or forced outages. The 1,190 megawatt San Onofre Unit 3 nuclear power plant was among that, having shut down for refueling. Another 1,600 megawatts worth of generation tripped off line over the weekend when something broke.On the best day in spring, with all plants operating and the state's rivers in full flow, Cal-ISO would have a little more than 44,000 megawatts of power at its disposal. That is a far cry from the 53,000 megawatts of generating capacity some state officials say the state has.The discrepancy is the one that accompanies comparisons of apples with oranges. Cal-ISO is responsible only for that portion of the transmission network owned by the state's three investor-owned utilities. The ISO can draw on the power generated only by plants owned by those utilities or the ones sold by them to independent power producers.The state officials, on the other hand, look at total in-state generation, which includes power generated in plants owned by municipal utilities, irrigation districts and rural electric cooperatives. The last time we looked, the Los Angeles Department of Water and Power, a municipal utility, owned about 6,500 megawatts of capacity.Today, about 33,000 megawatts are available to Cal-ISO, and Cal-ISO is going to need all of it.
