The Benefits of Net Metering Aggregation for Renewable Energy Systems

Is your business generating electricity through solar or other renewable energy generation systems? If so, then understanding how to fully benefit from the Net Energy Metering Aggregation (NEMA) program may be of great value to your operation.

NEMA, also known as “meter aggregation,” allows a single, centralized solar panel system to service multiple meters/service points.  Meter aggregation was made possible through SB 594 which Governor Jerry Brown signed into law in 2012. 

NEMA expands on the existing Net Energy Metering (NEM) program that allows a customer to receive a credit for the surplus electricity that is supplied to the electric grid. Expanded virtual net metering allows customers multiple meters to use on-site generation more efficiently and economically; however, meters on contiguous properties must be solely owned, leased, or rented by the eligible customer-generator to be included.    

Before NEMA, beneficiaries of NEM could either roll over the monetary value of any net surplus energy to the next billing cycle (of the meter to which the generating system is attached) or receive payment for any surplus energy at a lower rate.

NEMA has been implemented by PG&E, SCE and SDG&E at different levels since the end of 2013. Western Growers encourages members to explore the benefits of the meter aggregation for your operation.
