Cal. Pub. Resources Code § 25705
If the commission determines that all reasonable conservation, allocation, and service restriction measures may not alleviate an energy supply emergency, and upon a declaration by the Governor or by an act of the Legislature that a threat to public health, safety, and welfare exists and requires immediate action, the commission shall authorize the construction and use of generating facilities under such terms and conditions as specified by the commission to protect the public interest.
Within 60 days after the authorization of construction and use of such generating facilities, the commission shall issue a report detailing the full nature, extent, and estimated duration of the emergency situation and making recommendations to the Governor and the Legislature for further energy conservation and energy supply measures to alleviate the emergency situation as alternatives to use of such generating facilities.
