Sanford celebrates launch of 28-megawatt solar farm

SANFORD, Maine — Local and company officials gathered Nov. 20 to cut the ribbon on the Mousam River Solar Project, a 28-megawatt solar installation that marks a major milestone in Sanford’s clean-energy leadership.

Set on 140 acres off New Dam Road, the project features high-efficiency solar modules mounted on modern tracking infrastructure. Once fully operational, it’s expected to generate enough electricity to offset the power needs of nearly 6,000 average households.

“This is a great day for clean energy in Maine,” said Jack Kenworthy, chief development officer at Walden Renewables, which developed and operates the facility. “The success of this project reflects the collaboration between landowners, city officials, and our development team. Sanford has been an exceptional partner.”

The Mousam River Solar Project is one of the largest solar installations in southern Maine. It spans several privately owned parcels and is expected to provide long-term commercial tax revenue for the city, while supporting the state’s broader transition to renewable energy.

“Today’s ribbon cutting at Mousam River Solar is an outstanding achievement for Sanford and for Maine,” said Dan Burgess, acting commissioner of the Maine Department of Energy Resources. “I congratulate the local community and Walden Renewables on completing this project, which will generate affordable, reliable power here in Maine, create jobs and economic investment in the region, and provide long-term benefits for the community.”

City leaders say the project reflects Sanford’s commitment to sustainable development and economic growth. With construction now complete, the facility is poised to begin delivering clean energy to the region.

“Projects like this don’t just generate clean energy — they generate real economic value for Sanford,” said Deputy Mayor Maura Herlihy. “…It’s exactly the kind of investment that supports sustainable growth for our community.”

Cait Grant, vice president of York County Community College, also highlighted the project’s workforce implications.

“As renewable energy projects come online across the state, the need for well-trained technicians, electricians, and project specialists will only continue to grow,” she said. “We’re proud to help build that next generation of skilled professionals.”

Sanford now ranks among the top communities in Maine for solar capacity, with approximately 90 megawatts installed — second only to Farmington. Officials say that momentum is no accident, pointing to strong local support, access to transmission infrastructure, and a clear vision for clean-energy investment.
