Under California law (Public Utilities Code Section 2827), utilities were mandated to implement a net energy metering program by January 1, 2010 to compensate rooftop solar customers for extra energy generated until rooftop solar reached five percent of the utility’s peak demand. The program obligated California utilities to make NEM available to eligible customer-generators on a first-come-first-served basis. IID determined its NEM obligation to be 50.2 MW based upon a peak of 1004 MW in 2010, and reached that level ahead of schedule in early 2016.
In July 2016, IID made a policy decision to change its Net Metering Program to ensure that everyone pays their fair share for their use of the energy grid, including customers who choose to install rooftop solar systems on their homes. The Net Billing Program, which was approved by the board after extensive discussion, now aligns prices with the actual cost of providing power for all customers. This was a necessary solution that balances the interests of every customer IID serves in order to continue to deliver on our obligation to providing the greatest value at the lowest cost.
California Public Utilities Code §2827(c)(3)(A) requires electric utilities, including IID, to provide the board with information on the total rated generating capacity used by eligible customer-generators within its service area and the net surplus electricity purchased by the utility. Provided below is information related to the fully-subscribed net energy metering program and IID’s successor program, net billing.

The current price the district pays to customer-generators participating in the NEM and net billing programs for their net surplus electricity generated is approximately $685,740 annually. The current overall gross impact of IID’s distributed generation programs is estimated at $13.2 million annually. Considering the value of solar, the estimated net impact is $5.8 million.
