This guidance document explains requirements for the use of electric standby and hybrid electric systems as an option for compliance with California's TRU regulations' in-use performance standards. A TRU's compliance can be maintained beyond seven years if an electric standby or hybrid electric system is integrated into the equipment and used within the guidelines for an Alternative Technology.
