Committee flags three‑phase power as potential obstacle to large solar arrays
Summary
Members discussed that large solar arrays may require three‑phase service; Robert Irving said Mutton Road likely lacks three‑phase and relayed that Fire Chief MacDuffie told him the fire station does not have three‑phase service but could benefit from it.
Robert Irving raised a technical constraint, saying a large solar array would likely require a three‑phase power connection and that "Mutton road likely does not have three‑phase." He said he had discussed the issue with Fire Chief MacDuffie, who indicated the fire station does not have three‑phase service but could benefit from it.
Committee members noted that the presence or absence of three‑phase service will influence siting decisions and costs for larger installations. The group agreed Unitil should be asked whether three‑phase would be necessary for planned arrays and what upgrades, if any, would be required.
