LOS ANGELES (AP) — Operators of California’s electricity grid have declared a Flex Alert for Tuesday to encourage conservation as inland regions continue to swelter in high heat.
The California Independent System Operator said Monday that the forecast peak demand is 47,500 megawatts and conservation will be critical.
A Flex Alert was also called on Friday and Cal-ISO says consumers reduced demand by nearly 1,000 megawatts, equal to the output of two large power plants.
The National Weather Service has issued excessive-heat warnings for the central and southern San Joaquin Valley and from Santa Barbara County through southeastern California.
A wide area of mountains and adjacent deserts in the inland region east of Los Angeles is under a flash-flood watch because of very moist and unstable conditions that will produce afternoon thunderstorms.
