Fairhaven: FAQ

Where is Fairhaven?
In Anne Arundel County, Maryland (MD). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.
How big is Fairhaven?
3 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Fairhaven?
EIA-860M names Baltimore Gas & Electric Co as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.
Is this the same as Fairhaven LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Baltimore Gas & Electric Co here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Fairhaven LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Fairhaven still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
