California's power grid operator has lifted its call for statewide energy conservation this weekend, despite the continuing heat wave, though the Flex Alert continues through Friday at 6 p.m.
The California Independent System Operator says conservation will not be critical on Saturday and Sunday, based on forecast electricity demand.
It might be time to turn the air conditioning back on, especially if you're coming in after working out in the heat. The Occupational Safety and Health Administration recommends, for those working out in the heat, to schedule frequest rest breaks in the shade or in an air-conditioned environment. They also urge calling 911 in the event of heat stroke.
Cal-ISO notes that it is keeping watch on the power outlook for Monday.
The heat wave has brought triple-digit highs to the interior regions of California all week. Forecasters see a slight cooling trend early next week.
