Who owns Bromley Battery Storage?

Is this the same as Bromley Battery Storage LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Bromley Energy Storage LLC 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 "Bromley Battery Storage LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Bromley Battery Storage still running?
