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.

State Squeezes Through Another Hot Day

LCG, Aug. 2, 2000--The California Independent System Operator declared its daily Stage 2 "Power Watch" yesterday and is likely to do so again today, but so far during this five-day heat wave, the state has squeezed through with power to spare.

If a reserve margin of about 2 percent can be called "power to spare."

Peak demand on the statewide electrical grid yesterday was 45,503 megawatts and Cal-ISO said it expects that to increase to 45,723 megawatts today. Those figures are awfully close to the state record of 45,884 megawatts, set on July 12 of last year.

Cal-ISO has three levels of power watch. When reserves look like they are going to be tight, a Stage 1 power watch is called, and customers are asked to reduce their electricity consumption by drying the laundry at midnight and setting the air-conditioner thermostat a notch higher.

If that doesnt do the trick, Cal-ISO will declare a Stage 2 power watch, like yesterday and today. Stage 2 involves service interruption to customers with interruptible power contracts with their utilities.

If demand exceeds available capacity, a Stage 3 power watch would be called. Involuntary service interruptions, or rolling blackouts, would begin and wouldnt stop until the emergency had passed.

Cal ISO hasnt had to call a Stage 3 emergency, but all it would take is one big power plant to trip off line, or a high voltage transmission line to short out to a tree.

California imports about a quarter of its power from other states, over high voltage transmission lines. In the summer of 1996, one of those lines in Oregon shorted out to a tree. The load was shifted to other lines and they shut down. Pretty soon, power plants in California began shutting down to protect themselves. This all happens automatically.

Eventually, in that incident four years ago, a massive power outage affected the 13 western states.
