Residential and commercial projects may receive net-metering offset payments for electricity generated by the project. Commercial projects also pay federal and state income tax on the payments as shown in the explanation for after tax net equity cash flow above. The electricity purchase price is equal to Flat Rate on the Utility Rates page.
Offset Payments =
Electric Output x Electricity Purchase Price
