Do you plan to adjust your household energy use during extreme heat waves?

California utility providers are preparing for increased demand as a heatwave sweeps across the state. The California Independent System Operator has issued a Restricted Maintenance Operations notice for October 12 and 13 to help maintain grid stability.

Why it matters

Utilities are requesting voluntary conservation to reduce the risk of power outages caused by surging demand for air conditioning. Managing grid load during extreme weather remains essential to preventing widespread service interruptions.

The California Independent System Operator has initiated Restricted Maintenance Operations effective from 10 a.m. to 10 p.m. during the impacted days. Officials advise residents to set thermostats to 78 degrees or higher to alleviate grid pressure.
