Assembly Solar Project: FAQ

- 50 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns Assembly Solar Project?
- EIA-860M names Assembly Solar I, LLC 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 Assembly Solar Project LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Assembly Solar I, 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 "Assembly Solar Project LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
