Electric Vehicle (EV) Charger Uptime Reporting Standards

The California Energy Commission (CEC) in collaboration with the California Public Utilities Commission (CPUC) developed uptime recordkeeping and reporting standards for EV chargers purchased through a state incentive program or rate payer charges. For these standards, EV chargers must meet a 97% uptime requirement and share real-time data on the availability and accessibility of chargers. Standards vary by technology type, power level, number of chargers per site, and site ownership model. EV charger uptime data must be reported for a minimum of six years. These standards only apply to EV chargers installed on or after January 1, 2024, and do not apply to residential dwellings with less than five units.

CEC and CPUC must adopt tools to increase charger uptime, including uptime requirements, operation and maintenance requirements, or operation and maintenance incentives. By January 1, 2025, CEC must set standards for how charger operators notify customers about availability and accessibility of public EV charging infrastructure.

Beginning January 1, 2025, the CEC must assess the uptime of EV chargers. The assessment must include considerations for equitable access to EV chargers in low-, moderate-, and high-income communities. The assessment must be updated every two years. For more information, see the CEC website.
