Saltwind Energy Clears the Path for a Community Solar Array
A 28-megawatt project on reclaimed industrial land would sell shares to households and small firms blocked from rooftop installs.
Saltwind Energy received final zoning clearance for a 28-megawatt community solar array on the old kiln grounds east of the channel, the company announced Monday.
The vote at the regional land use commission was 6–1, with one abstention, after a hearing that ran past eleven and drew forty-one speakers. It closes a permitting process that began in September 2023 and survived two continuances, a revised stormwater plan, and a challenge to the parcel's contamination closure letter that the state resolved in Saltwind's favor last November.
Unlike utility-scale farms that sell only into the wholesale market, the project is structured so residents and small businesses can buy subscription shares and receive bill credits. Priority windows open first for households within a five-mile radius and for renters who cannot install panels.
The share structure is unusually granular. The smallest subscription is a quarter-kilowatt block priced at $310, which Saltwind estimates returns between $34 and $41 a year in credits at current rates. Households enrolled in the utility's low-income rate class can subscribe with no upfront payment and repay from credits, a provision the company added in the third round of hearings after sustained pressure from tenant organizers.
Environmental groups that opposed earlier proposals said the current plan's pollinator ground cover and stormwater design addressed their main concerns.
"It is not wilderness," said advocate Rowan Fields. "It is a better use of a scarred parcel."
Fields led the coalition that killed Saltwind's 2022 proposal for a site three miles north, on wet meadow that hosted a documented breeding population of shorebirds. He is careful to say the reversal is not a conversion. "We did not become fans of solar developers," he said. "They stopped asking for the wrong field."
## What the ground was
The kiln grounds ran as a brick and refractory works from 1911 until 1978, and then as an unpermitted equipment yard for most of the decade that followed. Sixty-one acres are capped. Nothing can be built there with a conventional foundation, which is precisely why the parcel sat on the tax rolls at a nominal valuation for twenty-two years while every other buildable acre east of the channel was spoken for.
Saltwind's racking is ballasted — concrete blocks sitting on the cap rather than piles driven through it. Project lead Mira Cho said the design added roughly $2.6 million to construction cost against a driven-pile alternative and was never seriously debated internally. "You do not put holes in a cap to save money," she said. "That is how a solar project becomes a Superfund story."
Financing blends tax equity, a green bond from Meridian Cooperative Bank, and a state resilience grant. The bond closed at $19.4 million in March. The resilience grant, $6.8 million, carries a clawback if the project fails to enroll 400 low-income subscribers within thirty months of commercial operation — a condition Cho called "fair and genuinely uncomfortable."
Construction is slated to begin after the autumn migration window, with a target energization date of March 2028.
## The objection that has not gone away
Critics still question interconnection costs and whether credits will keep pace with rate changes. The interconnection study came back at $8.2 million, roughly double Saltwind's 2023 planning estimate, and the utility's cost allocation is under appeal.
The rate question is sharper. Bill credits are pegged to a tariff the public utilities board revisits every three years. Subscribers pay a fixed price today for a credit whose value the board could reduce in 2029 or 2032, and nothing in the subscription contract prevents that.
Halvard Teng, a retired actuary who has appeared at every hearing on the project since the first one, has made this his single issue. He does not oppose the array. He opposes the sales pitch.
"They are selling a thirty-year asset against a three-year price," Teng said. "I have asked four times for the sensitivity table — what happens to a subscriber's payback if the credit rate falls fifteen percent in 2029 — and I have been handed a brochure four times."
Cho does not dispute the underlying risk. She said contracts will be written in plain language and reviewed by an independent consumer advisor, and that Saltwind will publish a downside scenario in the subscription materials rather than only a base case. Asked whether the company would guarantee a floor on credit value, she said no. "We cannot promise something the board controls. We can promise we will not pretend the board does not exist."
Teng, told of that answer, said it was the first responsive thing he had heard in three years and still not a table.
If subscriptions fill on schedule, Saltwind says a second phase could double capacity by 2029 without expanding the fence line — a claim that depends on panel efficiency improvements the company has not specified and on the interconnection appeal going its way.
Subscription enrollment opens on May 18 at a storefront office on Quarry Road, in a building that was the brickworks' pay hut and still has the barred window where wages were handed out through a slot. Saltwind is keeping the bars. Cho said the contractor offered to remove them and she asked him not to.
"People should be able to see what the ground used to be for," she said. "It makes the argument better than we do."
