Massachusetts State Solar Overview
Massachusetts has one of the most mature solar markets in the United States, supported by strong state policies, net metering, and incentive programs.
A recent study by SEIA and Synapse Energy Economics found that continuing the state’s leadership on solar and storage would deliver more than $313 million in annual consumer savings by 2030 and stronger winter grid reliability.
The SMART program continues to play a central role in driving solar deployment, particularly for distributed generation, alongside broader clean energy goals and grid modernization efforts.
As the market evolves, Massachusetts is increasingly focused on integrating solar with energy storage, managing grid constraints, and refining compensation structures to support continued growth.
SEIA Massachusetts State Policy Priorities
Three of SEIA’s top policy priorities in the Commonwealth include:
- Supporting ongoing implementation and refinement of the SMART program to ensure long-term market stability and continued solar deployment.
- Advancing improvements to interconnection processes to reduce delays and enable more efficient integration of distributed solar and storage resources.
- Engaging in regulatory proceedings to address grid constraints, compensation mechanisms, and project timelines as the market matures.
