The California Independent System Operator is calling for voluntary electricity conservation from 5:00 p.m. to 9:00 p.m. over the next two days.
That means you are being asked set air conditioners to 78 degrees or higher and to not use other appliances during these peak hours.
On hot days like this, cooling centers and community pools are open for free throughout the Valley, including Fresno and Merced Counties.
