Before 2023, EIA reported storage paired with photovoltaic inside the photovoltaic group; from 2023, batteries are their own group, paired with photovoltaic or not. Neither is added into photovoltaic here.

Distributed generation that is not net metered
A different arrangement: customer-sited or utility-owned generation that is paid or credited some other way, or not at all. EIA reports it separately, and it is not added to the net metering figures.

Community solar
Massachusetts has 608 community solar projects serving customers, 1,087.2 MW-AC in all, in the National Laboratory of the Rockies' list as of September 2026.
| Subscriptions marketed by | Projects | Capacity (MW-AC) |
|---|---|---|
| Third Party | 595 | 1,058.8 |
| Utility | 13 | 28.3 |
In queue: market tracking, not a registry
The laboratory also tracks 1.9 MW-AC as in queue here as of September 2026: awarded, under construction, or likely to come online in the next few years.
Projects in queue change without notice, and many are never built. This figure is kept apart from the capacity serving customers and never added to it.
These counts and capacities are our own sums of the laboratory's project list; its license keeps us from publishing a copy of the list itself. About the dataset
