Norfolk Board presses NextG Grid for safety metrics, transparency on Pond Street battery storage

The Norfolk Board of Health pressed NextG Grid on safety monitoring and public transparency for a proposed Pond Street community solar installation with battery storage at its June 30 meeting.

Board member Andy Bakinowski, who said he supports solar projects, told Daniel Serber of NextG Grid that he had submitted written comments and remained concerned about changes in the project’s battery system and possible particulate emissions. “My interest was more in the fact that the particulate matter… the reports that have been done… by Next simply didn’t have any particulate matter,” Bakinowski said, adding he had shared a picture of a Tesla battery fire as an illustrative example.

John Bowman, the board clerk, and other members pressed for measurable safety metrics — examples included counts of alarm calls, system downtimes, liquid‑cooling failures and OSHA log information — and asked NextG Grid to present operations‑and‑maintenance data one year after the site reaches full operation. "I'm asking for some level of transparency," Bowman said, describing the requested metrics as a way to tell a clear safety story to town residents.

Daniel Serber, representing NextG Grid, said the project is a community solar installation enrolled in the Massachusetts SMART program and described the customer‑aggregation approach. He said 51% of the project’s power is dedicated to low‑income residents and 49% to other subscribers, and that bill credits begin only after the system produces energy. On monitoring, Serber said system performance is computer‑logged and the operator can produce weekly, monthly or annual reports. “Everything you've said is an output that we would get as part of the normal operations and maintenance process,” he said, offering to make such logs available to the town on request.

Chief Kenny of the fire department told the board the department has held preliminary training with an experienced trainer and that the battery containers themselves are constructed to be highly robust. He emphasized that human and animal interference are frequently the cause of failures and said training and live‑fire simulations increase the department’s readiness.

Board members also raised local hydrogeologic questions and provided NextG Grid maps showing the site’s relationship to a nearby Zone 2 area; members asked the company to review those materials as part of the town’s evaluation. Several members suggested planning‑board conditions could require operations logs be available to the town and that the planning board and board of health coordinate on any site‑plan conditions tied to safety reporting.

Next steps: board members said they will share example metrics (including a set of conditions used by another town) with NextG Grid and with the planning board; NextG Grid agreed to provide monitoring outputs on request and to participate in the town’s review. The board continued a separate public hearing on bodyworks regulations to the July 28 meeting and will revisit any next steps related to the Pond Street project as part of that review and ongoing planning‑board processes.
