California grid operators warned residents to prepare for voluntary energy cuts and other emergency measures, such as turning down the air conditioning and forgoing electric vehicle charges, as the state braces for a period of excessive heat expected to last through Tuesday.

The California Independent System Operator said in a statement it is taking measures to bring “all available resources” online ahead of the heat wave, which is expected to be the longest and most severe high-heat period to hit the state so far this year.

An excessive heat warning is in effect through much of Southern California, with the National Weather Service warning of “dangerously hot” conditions that could climb as high as 115 degrees in some parts of the state.
