Conservation is needed because of power demands primarily from more air conditioning and other equipment in use to keep cool. It remains in effect as the sun goes down because solar power production decreases even as the heat remains into the evening.
The ISO asks Californians:
- Keep air conditioning at 78 degrees. You can also “pre-cool” your home by setting it at a colder temperature in the morning before power demand peaks.
- Defer use of major appliances.
- Turn off unnecessary lights and unplug unused devices.
- Close blinds and drapes.
