(a) The Legislature finds and declares that it is the public policy of this state to ensure the health and safety of highly vulnerable persons residing in skilled nursing facilities during power outages that may result from a public safety power shutoff, an emergency, a natural disaster, or other cause.
(b)
1. (1) A skilled nursing facility shall have an alternative source of power to protect resident health and safety for no fewer than 96 hours during any type of power outage.
2. (2) For purposes of this section, “alternative source of power” means a source of electricity that is not received through an electric utility but is generated or stored onsite, which may include, but is not limited to, emergency generators using fuel, large capacity batteries, and renewable electrical generation facilities.
(c) For purposes of this section, “resident health and safety” includes, but is not limited to, maintaining a safe temperature for residents, maintaining availability of life-saving equipment, and maintaining availability of oxygen-generating devices.
(d) A facility that uses a generator as its alternative source of power shall maintain sufficient fuel onsite to maintain generator operation for no less than 96 hours or make arrangements for fuel delivery for an emergency event.

(e) A facility that uses batteries or a combination of batteries in tandem with a renewable electrical generation facility as its alternative source of power shall have sufficient storage or generation capacity to maintain operation for no fewer than 96 hours. A facility shall also make arrangements for delivery of a generator and fuel in the event power is not restored within 96 hours and the generation capacity of the renewable electrical generation facility is unable to provide sufficient power to comply with state requirements for long-term care facilities.
