T.E.S. Filer City Station Limited Partnership owns a roughly 72 megawatt cogeneration plant at Filer City, Michigan, near Manistee, which began commercial operation in 1990.

It is held in equal halves by Tondu Corporation and the CMS Energy generation business now trading as NorthStar Clean Energy, which operates the site, and the owners have advanced a plan to convert it to run wholly on biomass with carbon capture, using Babcock & Wilcox technology sized to capture up to 550,000 tons of carbon dioxide a year.

T.E.S. Filer City Station Limited Partnership files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from TES Filer City Station (NorthStar Clean Energy), Filer City Station (Global Energy Monitor) and Michigan coal plant eyes BECCS retrofit (POWER Magazine). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- CMS Energy Corporation. Coal-fueled power generator; long-term PPA between the partnership and Consumers Energy plus an employee assignment agreement. A limited partnership interest, not shares of stock, so 'shares' is left null. No individual dollar value is disclosed: CMS Energy's consolidated balance sheet carries a single combined 'Investments' line ($63 million at 30 Jun 2026, $61 million at 31 Dec 2025, in Total other non-current assets) that is not broken out by investee and, per the project's combined-balance rule, cannot be assigned to this or any of the other three equity-method partnerships below. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of T.E.S. Filer City Station Limited Partnership where a holder stated one, and are missing where no holder did.
