Final Observations and Recommendations of the GMAC

Pursuant to G.L. c. 164, §§ 92B and 92C, the Grid Modernization Advisory Council (GMAC) provided its recommendations to the electric distribution companies (EDCs) on their first draft electric-sector modernization plans (ESMPs) on November 20, 2023. The Final GMAC Report includes the Observations and Recommendations of the Grid Modernization Advisory Council, including the Memorandum of the GMAC Equity Working Group, and other appendices.

This document was voted on and approved by the GMAC on November 16, 2023.

The GMAC thanks the stakeholders, EDCs, Equity Working Group, consultants, and many others who assisted in the review of the ESMPs and creation of this report, and looks forward to the Department of Public Utilities’ review of these plans.

Grid Modernization Advisory Council (GMAC)

Pursuant to G.L. c. 164, §§ 92B-92C, the Grid Modernization Advisory Council (GMAC) is charged with reviewing and providing recommendations to the state’s investor-owned electric distribution companies’ (EDCs) electric-sector modernization plans (ESMPs). The EDCs develop ESMPs for their respective customer service areas. Each ESMP will include, among other items, a summary of all reviewed, under consideration, or previously approved distribution system investments and alternatives, distribution system improvements to increase system reliability and resiliency for weather and disaster-related risks, distribution system improvements to facilitate transportation and building electrification, forecasts considering 5 and 10 year horizons as well as an assessment of demand through 2050. Once the GMAC has reviewed and provided recommendations, the EDCs will make appropriate revisions to their plan and file it with the Department of Public Utilities.  

The GMAC and ESMP system was set in place by “An Act Driving Clean Energy and Offshore Wind” (Climate Law) in 2022. The Climate Law requires that the state's EDCs prepare the ESMPs to proactively upgrade the distribution system and meet multiple objectives, including:

  • Improve grid reliability, communications, and resiliency;
  • Enable increased, timely adoption of renewable energy and DERs;
  • Promote energy storage and electrification technologies for decarbonization;
  • Prepare for climate-driven impacts on T&D systems;
  • Accommodate transportation and building electrification, and other new loads; and
  • Minimize or mitigate impacts on ratepayers.

The Governor appoints GMAC members who serve for five-year terms. The Commissioner of the DOER chairs the GMAC, which is supported by DOER staff. GMAC members, voting and non-voting, represent a wide array of organizations and interests.

The Council and the ESMPs represent an opportunity for the Commonwealth to increase transparency and broaden stakeholder engagement to the grid planning process. They will support better alignment of distribution system planning and investments with the Commonwealth’s ambitious climate requirements and focus on equitably serving all residents.

During its first meeting on March 31, 2023, the Council adopted by unanimous vote governing documents including by-laws, ground rules, a remote participation policy, and an Executive Committee charter.
