When temperatures rise in summer, so does demand for electricity across the state, particularly in the form of increased air conditioning use. Heightened demand can also coincide with reduced energy imports due to neighboring states facing similar heat patterns, and reduced in-state hydroelectric power production due to drought. Wildfires can also disrupt power generation and transmission lines, further impacting supply. To keep Californians safe and ensure a successful transition to a reliable, affordable, clean energy future, the state is working to rapidly deploy new projects and maintain existing resources for emergency use. Consumers are also encouraged to participate in conserving electricity when possible as outlined below.
Ways to Help
The public, consumers and businesses can do their part to help when California experiences extreme weather that causes tight energy supplies. Here are some ways to help:
- Voluntarily conserve energy during a Flex Alert
- Get paid to conserve energy during grid emergencies through new and innovative demand response programs:
