The Department shall publish a Guideline on Demand Response Resources to explain the parameters of Demand Response Resources in the Clean Peak Standard. A facility that generates electricity, including a Qualified RPS Resource, shall not be considered a Demand Response Resource.(2)Metering. A Clean Peak Resource shall meter and report 15-minute interval performance in compliance with standards and protocols as established by a third-party Program Administrator designated by the Department. The Department may grant an exception to the 15-minute interval and designate a shorter or longer interval on a case-by-case basis.

All standards and metering protocols shall be subject to review and approval by the Department. A Clean Peak Resource shall submit metered data to the Program Administrator for all hours of the previous month. Subject to review and approval by the Department, the Program Administrator may assess Clean Peak Resources a fee associated with the administration of the CPS. The electrical energy output or performance of a Clean Peak Resource shall be verified by the Program Administrator for the purpose of calculating the number of Clean Peak Energy Certificates a qualified resource produced in the previous month. The Program Administrator shall report the number of Clean Peak Energy Certificates each qualified resource is due to receive to NEPOOL GIS for the purpose of minting Clean Peak Energy Certificates.
(3)Clean Peak Seasons. (a) The four Clean Peak Seasons are established as:1. Spring: March 1st through May 14th;2. Summer: May 15th through September 14th;3. Fall: September 15th through November 30th;4. Winter: December 1st through February 28th; and as adjusted by leap years.(4)Seasonal Peak Periods. The Seasonal Peak Periods establish the time of day in which a qualified resource produces Clean Peak Energy Certificates.

Clean Peak Resources which are owned by a Distribution Company are not eligible for a Distribution Circuit Multiplier. The Department may consider Distribution Circuit Multipliers greater than or less than one. The Department, in coordination with the Distribution Companies, shall determine whether sufficient data is available to enable effective implementation of a Distribution Circuit Multiplier no later than December 31, 2022.

The Near-term Resource Multiplier modifies the number of Clean Peak Energy Certificates generated by a Qualified Energy Storage System that is not co-located with a Qualified RPS Resource or a Demand Response Resource and is interconnected to the Distribution System. The Qualified Energy Storage System must not have received a Statement of Qualification on or before January 1, 2025, and must have a Commercial Operation Date before January 1, 2027. No Qualified Energy Storage System shall receive both the Distribution Circuit Multiplier and the Near-term Resource Multiplier. The Department shall set an initial eligibility cap for the Near-term Resource Multiplier of 50 MW of cumulative Qualified Energy Storage System capacity. After notice and opportunity for public comment, the Department may increase this cap in the future. No individual or affiliated Owner, Operator, or Authorized Agent may qualify for greater than 50% of the capacity designated by the Department. The multiplier shall be two for years one through ten from the Qualified Energy Storage System's effective date on its Statement of Qualification. The Department may publish a guideline that explains the parameters of the applicability of the Near-term Resource Multiplier.(i)Review. Beginning in 2024 and not less frequently than every four years thereafter, the Department shall conduct a review of the Clean Peak Energy Certificate Multipliers and, following stakeholder review and input, may modify the multipliers.(7)Special Provision for Clean Peak Energy Certificate Generation for Energy Reserves. (a) The Department may establish a mechanism by which Clean Peak Energy Certificates may be generated by provision of energy reserves, subject to applicable requirements including, but not limited to, such provision of energy reserves being directly measurable and verifiable in accordance with 225 CMR 21.05(2). The Department shall determine whether such a mechanism can be implemented no later than December 31, 2020. If the Department determines that such a mechanism shall be established, the Department shall publish a Guideline on Energy Reserves that explains the mechanism and its applicability.(8)Clean Peak Certificate Procurement.(a) Each Distribution Company shall competitively procure Clean Peak Energy Certificates pursuant to M.G.L. c. 25A, § 17(c). Clean Peak Certificate procurements shall be designed to achieve an initial target of 30% of the total market obligation of Retail Electricity Suppliers in a given Compliance Year. The Department shall establish a staggered procurement schedule for the issuance for requests for proposals for Clean Peak Certificates.(b) The Department may adjust the procurement target in response to the Market Supply in any Compliance Year. Where Market Supply is below 50%, the Department may increase the subsequent year's procurement target by up to 5%. Where Market Supply is greater than 70%, the Department may decrease the subsequent procurement target by up to 15%. The Department may determine that additional procurements are not required based on Market Supply conditions.(c) A request for proposals to conduct the competitive procurement shall be developed by the Distribution Companies, in consultation with and subject to review and approval by the Department. Such request for proposals may include the following components:(d) Any contracts resulting from a competitive procurement under this section shall be subject to review and approval by the Department of Public Utilities.(e) The Department may establish a Guideline on Clean Peak Certificate Procurements that explains the parameters and provides additional detail to the procurement process.Adopted by Mass Register Issue 1423, eff. 8/7/2020.Amended by Mass Register Issue 1527, eff. 7/19/2024 (EMERGENCY).
