# California AB 1072 (20192020) — Public Utilities Commission: audits and reviews.

Under existing law, the Public Utilities Commission has regulatory authority over public utilities, including electrical, gas, heat, telegraph, telephone, and water corporations. The Public Utilities Act requires the commission to inspect and audit the books and records of each electrical, gas, heat, telegraph, telephone, and water corporation for regulatory and tax purposes. The act requires an inspection and audit to be done at least every 3 years if the utility has over 10,000 customers and at least every 5 years if the utility has 10,000 or fewer customers. The act alternatively authorizes the commission to inspect and audit the books and records of those utilities in accordance with the commission-approved general rate case cycle, if that cycle provides for a rate case no less frequently than once every 5 years. The act provides that an audit conducted in connection with a rate proceeding is deemed to fulfill these requirements.
