Codman Community Farm to draw all its power from the sun

(Editor’s note: this story was updated with corrected figures on April 8.)

Codman Community Farms will install solar photovoltaic panels on the roofs of three barns and that will provide 100% of the facility’s electricity by this summer.

Work will begin soon on reshingling the barns (which were last replaced more than 20 years ago) at a cost of $110,000, paid for via Community Preservation Act funds approved at last month’s Annual Town Meeting. SunBug will design and build the solar photovoltaic array at a cost of $150,000, but two grants totaling $50,000 will offset some of that. Donations to CCF (including its ongoing capital campaign) will cover the rest.

The 54 kW system will generate all the electricity CCF needs. “With our conversion to a high-efficiency heat pump, we will no longer be reliant on fossil fuels and will effectively become ‘net zero’,” said David Alperovitz, president of CCF’s Board of Trustees.

CCF qualified for the $20,000 grant from the U.S. Department of Agriculture’s Rural Energy for American Program (REAP) due to its robust farm activities, with more than 50% of its income derived from agricultural products. Codman is only the second nonprofit to receive a REAP grant and the first in many years. The other grant for $30,000 came from the Massachusetts Department of Agriculture Resources.

The farm will also save or earn roughly $15,000 a year on electricity and Solar Massachusetts Renewable Target (SMART) program tariffs, Alperovitz said. The state’s SMART program is a long-term sustainable solar incentive program that offers compensation for lean energy usage calculated as a proportion of the kilowatt hours of the electricity that a solar-powered facility produces.

Codman Community Farms will be the first town-owned entity to go solar, but certainly not the last. The Rural Land Foundation is hoping to build a 250 kW solar canopy in the mall parking lot this year, and the rebuilt Lincoln School, with a 700-770 kW system according to 2018 estimates, will be net zero for energy use when it comes online in 2023. The First Parish Church is also planning a 20 kW array.

Other nonresidential solar arrays are already up and running at St.-Anne’s-in-the-Fields Episcopal Church and in the meadow behind Lincoln Woods.

Further down the road, officials are hoping for town-owned solar PV arrays on the Public Safety Building roof and atop the transfer station. That complex project is still tackling issues such as getting access to the grid through land owned by Minute Man National Historical Park. If and when the two projects are completed, they could generate up to 50% of the electricity used by town facilities.

“Working with the town of Lincoln has been amazing,” Alperovitz said. “[Town Administrator] Tim Higgins and [Town Facilities Manager] Michael Haines have been enormously supportive and helpful, and without them this would not have been possible. They pushed for funding for the shingles to be redone in a time frame that’s in keeping with our grant restrictions, and they’ve allowed us to thread a fine needle (still in process) through many obstacles and hurdles.”

The Historic District Commission has also been “wonderful and supportive,” he added.

“I’m reveling in the fact that the farm buildings will soon be powered by the sun (our eggs are already washed by water heated by the sun as well), and the fact that establishing this system will help to put the farm on better footing financially for the years to come,” Alperovitz said.
