How big is Biron Mill?

62 MW of nameplate capacity across 4 units, as of the EIA-860M release for 2026-07.

EIA-860M names ND Paper, Inc. 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 Biron Mill LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — ND Paper, Inc. 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 "Biron Mill LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.

Is Biron Mill still running?

EIA-860M files it as "Out of service but expected to return to service in next calendar year" for 2026-07. Statuses change monthly, and this page follows the monthly release.
