LCG, November 13, 2026--The U.S. Energy Information Administration (EIA) today issued an "In-Brief Analysis" highlighting the record lows for hydropower generation in the Southwest this summer. The prolonged drought conditions affecting the Colorado River Basin caused record low hydropower generation this summer in the Southwestern electricity supply region, which includes Arizona, New Mexico, and small parts of Nevada and California. Hydropower generation from April through August 2026 was a full 28 percent lower than the 10-year average and 19 percent lower than during the same period last year.

Fires, Heat and Humidity Trigger Power Curtailment
LCG, Sept. 14, 2000Two wildfires burning near transmission line, a disappearing could cover that let in the sun and high humidity in the southern part of the state combined yesterday afternoon to cause the California Independent System Operator to declare a stage two electrical emergency and begin the process of curtailing power deliveries to large customers with interruptible contracts.Yesterday's power demand in the state had been forecast to peak around 4:00 p.m. at 41,500 megawatts, but chances are it went higher because it was a hot, muggy day the kind that air-conditioners are made for. Making matters worse, a fire near Castaic, just north of Los Angeles, threatened transmission lines, making it harder to get power to where it was needed most.Another fire, in the high Sierras east of Fresno, cut access to power that Cal-ISO was depending on to help maintain reliability on California's overloaded system.Cal-ISO directed SoCal Edison to reduce its electrical load by 862 megawatts. To achieve this load reduction, the company is required to activate its voluntary load curtailment program, under which large industrial, commercial, and agricultural customers, as well as customers on SoCal Edison's air conditioner cycling program, agreed to have their power temporarily interrupted in exchange for reduced rates.The curtailment measures are aimed at avoiding a stage three electric emergency, under which utilities would be directed to shed load through necessitating involuntary rolling, or rotating, outages for blocks of customers across their service areas until sufficient reserve levels are achieved."By all of us sticking together and cutting back power use as much as possible, we can get through this difficult period and possibly avoid a stage three emergency," Pam Bass, SoCal Edison's senior vice president for customer service, said.
