(1) Length of Compensation Rate Terms. All STGUs will be eligible to receive compensation under 225 CMR 28.00 for 20 years from the STGU's Incentive Payment Effective Date. STGUs under 225 CMR 28.07(5)(e)2. will be eligible to receive compensation from the Incentive Payment Effective Date for the first phase of the STGU until 20 years from the Incentive Payment Effective Date set for the STGU's total nameplate capacity. The Base Compensation Rate and Compensation Rate Adders contained in an STGU's Final Statement of Qualification shall be fixed for those 20 years, subject to any suspension or revocation issued pursuant to 225 CMR 28.17(3). (2) Base Compensation Rates. Base Compensation Rates for each Program Year will be established and published pursuant to 225 CMR 28.05(6) and shall be the same across all Electric Distribution Company service territories. STGUs less than or equal to 25 kW shall receive a Flat Incentive Rate pursuant to 225 CMR 28.14(3). Base Compensation Rates shall be established for the following capacity ranges: (a) 25 kW - 250 kW; (b) 250 kW - 500 kW; (c) 500 kW - 1,000 kW; and (d) 1,000 kW - 5,000 kW. (3) Compensation Rate Adders. Compensation Rate Adders for each Program Year will be established and published pursuant to 225 CMR 28.05(6) and shall be the same across all Electric Distribution Company service territories. energy Storage Adder Nominal Rated Power Capacity of l::nergyStora_ge S)rstem) DC Rated Capacity of the Solar Photovoltaic System =~--------------------------------------------------~• (( Nominal Rated Power Capacity of Energy Storage System) (o 7 - (a ( ominal Raced Power Capacity of Ener_qy Stora_qe System)))) DC Raced Capacity of the Solar Photoi,-olcaic System exp • • DC Raced Capacity of che Solar Photovoltaic Syscem [ 0 8 (0 l ( Nominal Rated Useful J::nergyof the Energy Storage System))] .

An STGU may add and/or remove a Compensation Rate Adder one time during its tariff term. An STGU that qualifies for a Compensation Rate Adder after its Commercial Operation Date may only receive the Compensation Rate Adder for the remainder of its tariff term, provided it can demonstrate continued compliance with the eligibility criteria. The value of each Compensation Rate Adder for which an STGU is eligible will be the applicable Compensation Rate Adder at the time the STGU qualifies for the Compensation Rate Adder. (b) Locational Compensation Rate Adders. Locational Compensation Rate Adders shall include: 1. Brownfield STGU; 2. Building Mounted STGU; 3. Canopy STGU; 4. Dual-use Agricultural STGU; 5. Floating Solar STGU; 6. Landfill STGU; 7. Large Building Mounted STGU; and 8. Raised Racking STGU. (c) Off-taker Based Compensation Rate Adders. Off-taker Based Compensation Rate Adders shall include: 1. Community Shared STGU; 2. Low Income Property STGU; and 3. Public Entity STGU. (d) Other Adders. 1. Pollinator Adder; 2. Solar Tracking Adder. (e) Energy Storage Adder. An STGU that meets the eligibility requirements of 225 CMR 28.07(5)(e)1. shall be eligible to receive a variable adder to its Base Compensation Rate. 1. Energy Storage Adder Multiplier. The energy storage adder multiplier will be published in the Department's Guideline on Base Compensation Rates, Compensation Rate Adders, and Annual Assessment and shall be the same across all Electric Distribution Company service territories. 2. Energy Storage Adder Formula. The variable energy storage adder for STGUs paired with Energy Storage Systems that meet the requirements of 225 CMR 28.07(5)(e)1. will be calculated using the below formula. The Department shall publish a Guideline on Energy Storage that provides an Energy Storage Adder calculator and explains the parameters of 225 CMR 28.13(3)(e)2. (f) Combining Base Compensation Rates and Compensation Rate Adders. 1. Combining Adders. An STGU greater than 25 kW can combine its Base Compensation Rate with no more than one Compensation Rate Adder from each of the two categories listed in 225 CMR 28.13(3)(b) through (c), provided it meets the eligibility criteria to qualify for each of the Compensation Rate Adders. 2. Exception for Brownfield STGUs. Qualification for the Brownfield STGU Locational Adder shall not count towards an STGU's count of Compensation Rate Adders under 225 CMR 28.13(3)(f)1.
