How the Solar Billing Plan Works

For customers considering solar and other renewable generation1 at their homes, the Solar Billing Plan is designed to help modernize solar rates to promote grid reliability, incentivize solar and battery storage, and help control electricity costs for all Californians. Each month, billing will include charges for energy used from the electric grid, as well as energy credits exported to the grid. 

1 Renewable generation includes solar, wind, renewable gas, and other technologies that satisfy the CEC Renewable Portfolio Standard (RPS) qualifications.

On the Solar Billing Plan, Energy Export Credits will be applied to the amount of electricity a customer exports to the grid and will reflect the electricity’s value to the electric grid during each hour of the day. Energy Export Credits will be calculated by taking the kilowatt hours generated by the customer’s generating system that is exported hourly to the grid multiplied by the Energy Export Credit prices. These EEC prices will vary hourly throughout the day and can be found here for both Pacific Time and Universal Time. Customers who enroll in the Solar Billing Plan before January 1, 2028, will have fixed EEC prices for the first nine years of operation. The nine years is referred to as the lock-in period.

Each year, the EEC Prices are calculated using the CPUC Avoided Cost Calculator (ACC) approved as of January 1 of the calculation year (the “vintage year”). For each “vintage year”, the simple average EEC Price is calculated for each month of a 9-year lock in period, and it is differentiated by hour (24 hours) and by weekdays and weekend/holidays. In addition, each hourly EEC Price is broken down in two components: (1) the Generation EEC Price (energy, cap and trade and generation capacity) component, and (2) the Delivery Service EEC Price (transmission, distribution, greenhouse adder and methane leakage) component.
