Haverhill Solar Power Project: FAQ

- 1 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns Haverhill Solar Power Project?

- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Massachusetts Electric Co here — not the project company that holds the asset.
