For each Billing Period, an Eligible Customer‐Generator will receive a bill credit for each kilowatt‐hour of energy supplied by their Renewable Electrical Generating Facility to the Utility. For each supplied kilowatt‐hour of energy, the energy credit shall be calculated by multiplying the Avoided Cost of Energy (ACOE) rate and, if applicable, the time of delivery factor (“Time of Delivery Factor”) for that supplied kilowatt hour. Each Billing Period, the bill credit will be used to offset the utility bill of the Eligible Customer‐Generator and, if there are any remaining energy credits, these energy credits will be applied to subsequent utility bills until the earlier of (1) the exhaustion of the energy credit; or (2) the termination of electric service. If any net energy credits exist at the termination of service, the Utility will pay the Eligible Customer‐Generator the value of the remaining energy credits.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with RPU - Riverside Public Utilities before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
