SMART 3.0 Program Details

This page contains information on the current version of the Commonwealth's SMART solar incentive program (225 CMR 28.00) for solar installers and developers. On this page you will find resources to participate in SMART, current incentive rates and capacity, program implementation guidelines, and regulatory updates.

Please note that the SMART 3.0 program is currently subject to an ongoing tariff proceeding before the Department of Public Utilities, docketed under 25-175. Please read the Tariff Proceeding section below for more details. 

* DOER will continue accepting applications and issuing Preliminary Statements of Qualification, but DOER will not be issuing Final Statements of Qualification until the tariff is approved. Please note that SMART incentive payments will not be backdated to the project's commercial operation date. The 20-year SMART tariff term will begin after DPU approval of the tariff and the issuance of a project's Final Statement of Qualification.

Program Regulations

On August 28th, 2025, DOER filed final regulations for the SMART 3.0 Program with the Secretary of State's Office, under 225 CMR 28.00. (See summary of program changes.) DOER also made a single redline edit to SMART 1.0 and 2.0 existing regulation, 225 CMR 20.00. The revised version of these regulations became effective upon publication in the Massachusetts Register on September 12, 2025. 

The final 225 CMR 28.00 regulations are linked below. 

Tariff Proceeding

On November 21, 2025, The Electric Distribution Companies (EDCs) jointly submitted a filing, docketed under 25-175, to the Department of Public Utilities (DPU) for review and approval of the proposed SMART 3.0 Tariff. The EDCs proposed that the DPU review the filing in two phases: 

  1. Non-controversial and clarifying changes to the tariff. 
  2. Additional revisions. 

The EDCs are not seeking approval of specific costs at this time.

Tariff Proceeding Status

DOER will update this page with the current status of the tariff proceeding and any pertinent information for program participants. You can also check the status of the proceeding in the DPU File Room, under Docket No. 25-175

  • On March 13, 2026, DOER filed a letter in the docket providing an overview of the annual SMART Program Assessment process, and the EDCs filed a revised version of the SMART 3.0 Tariff
  • On May 19, 2026, DPU approved the revised SMART 3.0 Tariff and ordered the EDCs to file company-specific SMART 3.0 Tariffs. DOER expects to start issuing Final Statements of Qualification once the company-specific SMART 3.0 Tariffs are approved by DPU. 

* DOER will continue accepting applications and issuing Preliminary Statements of Qualification, but DOER will not be issuing Final Statements of Qualification until the tariff is approved. Please note that SMART incentive payments will not be backdated to the project's commercial operation date. The 20-year SMART tariff term will begin after DPU approval of the tariff and the issuance of a project's Final Statement of Qualification. 

Annual Capacity and Rates

Per program regulations, DOER will publish an Annual Report with details on available capacity, set asides, and incentive rates for the applicable Program Year. In a given Program Year, DOER will accept applications from January 1 through December 31 of that year.

Program Year 2026

On October 1, 2025, DOER published the Draft Program Year 2026 Annual Report. DOER accepted public comments on the draft report until October 31, 2025.The public comments that DOER received on the Draft Annual Report can be found here: Public Comments.

Program Year 2026 Annual Report

Per the report, Program Year 2026 will have 600 MWAC of available capacityfor STGUs subject to the capacity cap.

Program Year 2026 Flat Incentive Rates (≤25 kW)

Small (≤25 kW AC) Solar Tariff Generating Units (STGUs) and Low-Income STGUs, as defined in 225 CMR 28.00, receive a flat incentive rate per kilowatt-hour (kWh) of energy generated (Solar Incentive Payment = $/kWh x kWh generated). Unlike other STGU types, these incentive rates are fixed for all STGUs of this kind, based on the previous year's average net metering credit value. The flat incentive rates for Program Year 2026 are shown in the table below. 

STGU TypeFlat Incentive Rate (2026)
STGUs ≤25 kWAC$0.03/kWh
Low Income STGUs$0.06/kWh

Program Year 2026 BTM Value of Energy Workbook

DOER has created a Value of Energy and Incentive Calculator for Behind-the-Meter facilities >25 kW AC. This calculator is intended to be a tool to calculate the Value of Energy and fixed incentive compensation rate for Behind-the-Meter systems. The calculation is based on project type, size, distribution company service territory, and customer rate class. This workbook does not necessarily reflect the final tariff value a system will be qualified for, but is available as a tool to help estimate the value that a particular customer may receive under different scenarios. This workbook will be in effect through December 31, 2026.
