California Code, Government Code - GOV § 8558

(c)(1) “Local emergency” means the duly proclaimed existence of conditions of disaster or of extreme peril to the safety of persons and property within the territorial limits of a county, city and county, or city, caused by conditions such as air pollution, fire, flood, storm, epidemic, riot, drought, cyberterrorism, sudden and severe energy shortage, deenergization event, electromagnetic pulse attack, plant or animal infestation or disease, the Governor's warning of an earthquake or volcanic prediction, or an earthquake, or other conditions, other than conditions resulting from a labor controversy, which are or are likely to be beyond the control of the services, personnel, equipment, and facilities of that political subdivision and require the combined forces of other political subdivisions to combat, or with respect to regulated energy utilities, a sudden and severe energy shortage or deenergization event that requires extraordinary measures beyond the authority vested in the Public Utilities Commission.

(2) A local emergency proclaimed as the result of a deenergization event does not trigger the electric utility obligations set forth in Public Utilities Commission Decision 19-07-015 or its successor decisions as related to deenergization events. A local emergency proclaimed as the result of a deenergization event does not alter the electric utilities' Public Utilities Commission-approved cost-recovery mechanisms for their own costs associated with deenergization events.
