This bill would revise and recast the definition of “electrical corporation” to, among other things, eliminate certain existing exceptions to the definition of “electrical corporation,” thereby expanding the scope of that term and the entities over which the CPUC has regulatory authority. The bill would additionally exempt from that definition a corporation or person employing one or more distributed energy resources, as defined, that has the capacity to be coupled with one or more energy storage systems for the generation of electricity primarily for specified uses. It would also exempt from the definition of “electrical corporation” a microgrid, as defined, that primarily serves the included load of the microgrid, as provided. Finally, the bill would require the CPUC to retain jurisdiction over the interconnection of a microgrid to the distribution system of a large electrical corporation, as defined.
