According to a report from The Daily Wire, California officials are begging residents to reduce the strain on the state’s power grid by not charging their electric vehicles while The Golden State gets hammered with a heat wave.

The California Independent System Operator is expected to issue a “voluntary energy conservation” notice for Labor Day weekend to free up resources for increased electricity consumption.

Residents experienced blackouts over last year’s Labor Day weekend.

“The warnings of low grid capacity come days after the California Air Resources Board issued new rules requiring 35% of new vehicles to produce zero emissions by 2026 — a standard that will rise to a 68% benchmark by 2030 and a 100% level by 2035. Yet experts have warned that the state’s electric grid will require significant upgrades to manage a rapid transition away from internal combustion vehicles,” DW reports.

“Today, most people charge their electric cars when they come home in the evening — when electricity demand is typically at its peak,” according to researchers at Cornell University’s College of Engineering. “If left unmanaged, the power demanded from many electric vehicles charging simultaneously in the evening will amplify existing peak loads, potentially outstripping the grid’s current capacity to meet demand.”

The western United States is facing a likely “prolonged and record heat wave” that could lead to temperatures as high as 115 degrees Fahrenheit, according to the National Weather Service.

In addition, to avoid charging your EV for the weekend, officials are also asking residents to set thermostats to 78 degrees or higher and avoid using large appliances, the American Public Power Association requested.
