California Governor Jerry Brown recently signed a new law that could significantly expand virtual net energy metering in California. Since 1996, California utility customers owning renewable energy systems have been able to offset their electricity bills with credits earned by feeding power generated by their systems back to the utility. SB 594 amends California’s net metering law to allow customers to aggregate energy consumed at multiple meters located on their property (or on their contiguous property) and net that use against the power produced by the customer’s renewable facility on the same site.

Meters on contiguous properties must be solely owned, leased, or rented by the eligible customer-generator to be included. Parcels divided by a street, highway, or public thoroughfare are considered contiguous provided that they are otherwise contiguous and under the same ownership. The customer-generator will be able to use the sum of the load of the aggregated meters for purposes of establishing the maximum size renewable generation system to be used for net metering purposes. However, the existing maximum size limit (1 MW) for net-metered generation facilities will apply to customer-generators aggregating multiple meters. Overall, expanded virtual net metering would provide a way for many customers with multiple meters to use on-site generation more efficiently and economically.

Implementation of SB 594 is contingent upon the California Public Utilities Commission (CPUC) making a determination that the expanded virtual net metering program established by the bill will not result in costs being shifted to non-participating ratepayers. The CPUC is required to make this determination by September 30, 2013.Continue Reading SB 594 Signed into Law: Intended to Expand Virtual Net Metering in California
