Palo Alto's NEM 1 program


The City of Palo Alto’s NEM 1 program meets the requirements of California state legislation. Customers who installed rooftop solar before November 2016 or who applied and were approved for the City of Palo Alto Utilities (CPAU) NEM 1 Reservation program prior to January 1, 2018 are served by the NEM 1 program. NEM 1 customers are compensated at retail rates for electricity they export to the grid for a term of 20 years from the date of system interconnection, as described in this City Staff Report.


After a customer's NEM 1 term is up, the customer is served by Palo Alto's NEM 2 program.


Customers who install rooftop solar after January 1, 2018, and who did not apply and receive approval for a NEM 1 Reservation are served by the City's NEM 2 program.
