Renewables

Graph shows aggregated output from renewables connected to the ISO grid.

Net Demand

The net demand curve depicts the variability in demand and supply that the ISO must counter balance to maintain grid reliability. Net demand is calculated by taking the actual demand and subtracting the electricity produced by variable generation resources, wind and solar, that are directly connected to the ISO grid.

Higher levels of variable electricity generation increases the ISO operational need for resources with the technological flexibility to start and stop quickly, and maintain output for set periods of time, so we can match supply and demand at all times.

Flex Alerts

Funded by the investor-owned utilities and authorized by the CA Public Utilities Commission, Flex Alerts are part of an educational and emergency alert program that informs consumers about how and when to conserve electricity. Go to flexalert.org for more information.
