Massachusetts Clean Energy Guide

Massachusetts is a national leader in offshore wind development and clean energy policy. With ambitious net-zero targets and the first commercial-scale offshore wind farm in the US, the state is pioneering the East Coast clean energy transition.

Offshore Wind Leadership

Massachusetts has positioned itself as the hub of US offshore wind development. The state's long coastline and strong, consistent winds make it ideal for offshore wind generation. Vineyard Wind 1, located 15 miles south of Martha's Vineyard, became the nation's first commercial-scale offshore wind project when it began operations in 2024.

Major Offshore Wind Projects

• Vineyard Wind 1: 806 MW, first US commercial-scale offshore wind farm, operational 2024
• New England Wind (formerly Commonwealth Wind): New England Wind 1 (791 MW) contracted in 2024, with New England Wind 2 (1,080 MW) in development south of Martha's Vineyard
• SouthCoast Wind (formerly Mayflower Wind): 2,400 MW total capacity in development phases; federal construction approval remanded by BOEM in late 2025, delaying the project at least two years

Supply Chain Development

Massachusetts is developing offshore wind manufacturing and assembly facilities. New Bedford Marine Commerce Terminal serves as a staging area for offshore wind components, while the state attracts blade manufacturing, foundations, and operations facilities to support the growing industry.

Solar Development

Despite its northern latitude, Massachusetts has built substantial solar capacity through aggressive incentive programs. The SMART (Solar Massachusetts Renewable Target) program provides incentives that have driven deployment across residential, commercial, and utility-scale segments.

SMART Program

The SMART program replaces the earlier SREC program with more predictable, long-term incentive payments. Under SMART 3.0, effective September 2025, capacity targets and incentive rates are set annually at the start of each program year, with a fixed incentive for projects under 25 kW and adders for storage, low-income participation, and brownfield development. The program has successfully driven deployment while reducing costs over time.

Climate Policy Framework

Massachusetts has one of the most comprehensive climate policy frameworks in the nation. The 2021 Climate Law established legally binding emissions reduction requirements: 50% below 1990 levels by 2030, 75% by 2040, and net-zero by 2050. The state's Clean Energy and Climate Plan details sector-by-sector strategies to achieve these goals.

Building Decarbonization

Massachusetts is pioneering building electrification policies. The state offers incentives for heat pump adoption, has updated building codes to encourage all-electric construction, and allows municipalities to adopt stretch codes and fossil fuel restrictions for new construction.

Key Developers Active in Massachusetts

• Vineyard Wind (Avangrid/Copenhagen Infrastructure Partners): Leading offshore wind developer
• SouthCoast Wind (Ocean Winds): Major offshore wind project developer
• Eversource: Major utility with clean energy investments
• National Grid: Utility supporting renewable integration
• BlueWave Solar: Leading community solar developer
• New Leaf Energy (formerly Borrego): Commercial and community solar developer

Challenges & Outlook

Massachusetts faces challenges including high electricity costs, limited land for utility-scale solar, and transmission constraints for offshore wind integration. The offshore wind industry has faced cost pressures and project delays due to supply chain issues and rising interest rates.

However, the state's strong policy framework, established offshore wind industry, and commitment to climate goals position it well for continued clean energy leadership. Success in offshore wind will be particularly critical for meeting the state's ambitious emissions targets.
