The California Independent System Operation Corporation issued a statewide Flex Alert on Monday, asking California residents to voluntarily conserve electricity through Wednesday evening.
Cal ISO, the state's power grid operator, urged people to conserve electricity between 2 p.m. and 9 p.m. Tuesday and Wednesday to help avoid potential power outages caused by increased air conditioner use.
The week's hot temperatures are expected to drive up people's use of air conditioners, which can strain the power grid. "Consumers are urged to voluntarily conserve electricity to help avoid more serious steps to protect the power grid, including local rotating outages," the agency said in a statement.
"Consumers can help avoid power outages by turning off all unnecessary lights, using major appliances before 2 p.m. and after 9 p.m., and setting air conditioners to 78 degrees or higher," the agency said.
• Set thermostat at 78° or higher and turn off, if away
• Cool with fans and draw drapes
• Turn off unnecessary lights and appliances
• Use major appliances in morning or late evening
