Title 225 CMR 20.00 - Solar Massachusetts Renewable Target (SMART) Program
Section 20.08 - Calculation of Incentive Payments for Solar Tariff Generation Units
Current through Register 1531, September 27, 2024
(1) Calculation of Incentive Payments for Standalone Solar Tariff Generation Units. Any payments provided to the Owner of a Standalone Solar Tariff Generation Unit, which meets the criteria of 225 CMR 20.08(1)(a) or (b), will be equal to total of the Solar Tariff Generation Unit's Base Compensation Rate plus any Compensation Rate Adders minus any Greenfield Subtractor, multiplied by the total kWh generated by the Solar Tariff Generation Unit in the Distribution Company billing period, minus the value of the energy generated by the Solar Tariff Generation Unit in a Distribution Company billing period.
Standalone Solar Incentive Payment
= (Base Compensation Rate + Compensation Rate Adders
- Greenfield Subtractor) * total kWh generated
- value of energy generated
Net Metered Generation Unit Energy Value
= total kWh Generated * net metering credit rate
Alternative On-bill Credit Generation Unit energy value = total kWh generated * energy compensation rate
Non-net Metered Generation Unit energy value
= total kWh generated * State Qualifying Facility value
(2) Calculation of Incentive Payments for Behind-the-Meter Solar Tariff Generation Unit. Payments provided to the Owner of a Behind-the-Meter Solar Tariff Generation Unit by a Distribution Company for RPS Class I Renewable Generation Attributes and Environmental Attributes will be fixed at the point in time that a Solar Tariff Generation Unit receives its Statement of Qualification for the duration that the Solar Tariff Generation Unit is eligible under 225 CMR 20.00 and will be equal to the total of the Solar Tariff Generation Unit's Base Compensation Rate plus any Compensation Rate Adders minus any Greenfield Subtractor, minus the value of energy, multiplied by the total kWh generated by the Solar Tariff Generation Unit in the Distribution Company billing period.
Behind-the-meter Solar Incentive Payment
= [(Base Compensation Rate + Compensation Rate Adders
- Greenfield Subtractor) - value of energy] *total kWh generated
The methodology for calculating the value of the energy for a Behind-the-meter Solar Tariff Generation Unit is dependent on whether the Generation Unit is qualified as a Net-metered Generation Unit, an Alternative On-bill Credit Generation Unit, or a Non-net Metering Generation Unit, and will be determined as follows:
Net-metered value of energy
= (distribution kWh charge + transmission kWh charge
+ transition kWh charge)
+ three-year average of basic service kWh charge)
Alternative on Bill Credit and Non-net Metered value of energy
= [0.65 (three year average of basic service kWh charge
+ distribution kWh charge + transmission kWh charge
+ transition kWh charge
+ 0.35 (three-year average of basic service kWh charge)
