Summer isn’t over yet. Judging by this weekend’s forecast and beyond, there is minimal relief in sight.
The California Independent System Operator (Cal ISO) issued a statewide Flex Alert today that calls for voluntary electricity conservation from 1 p.m. to 10 p.m. on Friday, September 1. Consumers are urged to conserve electricity especially during the afternoon when air conditioners typically are at peak use, as well as turn off all unnecessary lights, use major appliances before 1 p.m. and after 10 p.m., and set air conditioners to 78 degrees or higher to avoid any interruptions.
Forecasts now project record demand load on Friday and all available resources are ready to respond. The ISO’s service territory serves about 80 percent of California’s electricity consumers.
A Flex Alert is issued by the ISO when the electricity grid is under stress because of generation or transmission outages, or from persistent hot temperatures.
Conservation tips include:
- Set thermostat at 78 degrees 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
A grid operator monitors the daily forecast and has the ability to notify businesses, local governments, residents and state agencies by media reports or emails. These alerts are typically regionally targeted and grid operators can shift energy resources within different regions to handle anticipated demands.
