CPS Guidelines

The Department of Energy Resources (DOER) has published guidelines on the topics listed below in order to support the Clean Peak Energy Standard regulation and provide further clarification to stakeholders.

Guidelines include:

  1. Clean Peak Resource Eligibility Guideline
  2. Clean Peak Demand Response Resource Guideline
  3. Clean Peak Energy Reserves Guidelines
  4. Clean Peak Distribution Circuit Multiplier Guideline
  5. Clean Peak Determination of Sales Guideline

CPS Qualified Units List

Qualified Clean Peak Resources are listed here on the Qualified Units List. These units have met all the eligibility requirements to participate under the Clean Peak Energy Standard. Their NEPOOL GIS Certificates are known as Clean Peak Energy Certificates or CPECs. CPECs can be used only for compliance with the Massachusetts Clean Peak Energy Minimum Standard, not for any other energy portfolio standard

Actual Monthly System Peak Report

The Actual Monthly System Peak is defined in the Clean Peak Energy Standard as the highest net demand for electricity in a calendar month in ISO-NE Control Area. The Hour of Actual Monthly System Peak is the hour in which that occurs. DOER utilizes that monthly ISO-NE reported peak to identify when the Actual Monthly System Peak Multiplier should modify the number of Clean Peak Energy Certificates generated by a Clean Peak Resource.

Minimum Standard

2020 Clean Peak Minimum Standard

Pursuant to M.G.L. Ch. 25A Section 17(a), DOER is required to annually increase the Minimum Standard by not less than 0.25 percent of kilowatt-hour sales by retail electricity suppliers in the Commonwealth.  DOER has determined that 1.5 percent of sales by retail electricity suppliers in the Commonwealth shall be met with Clean Peak Energy Certificates in the 2020 compliance year.

2019 Clean Peak Minimum Standard

Pursuant to Chapter 227 of the Acts of 2018, not later than December 31, 2018, DOER was required to establish the baseline minimum percentage of kilowatt-hours sales to end-use customers that shall be met with clean peak certificates beginning on January 1, 2019.

After reviewing available information, the statutory definition of clean peak resources, and a number of other factors, DOER determined that approximately 0 MWh were being served by existing clean peak resources during peak load hours as of December 31, 2018, and established the Minimum Standard percentage requirement for retail electricity suppliers in the 2019 compliance year at 0%
