Who owns Grayling Generating Station Limited Partnership
One company in the researched set discloses a stake in Grayling Generating Station Limited Partnership, none of it sized by anyone who discloses it.

Grayling Generating Station Limited Partnership owns a 38 megawatt biomass power plant near Grayling in northern Michigan that has been running since 1992. It burns wood waste, mainly bark and sawdust from local lumber mills together with non merchantable material left from logging, plus tyre derived fuel, and generates roughly 230,000 megawatt hours a year, enough for about 38,000 homes. The output is sold to Consumers Energy under a long term power purchase agreement, and the plant is operated by NorthStar Clean Energy, the non utility arm of CMS Energy. Because it consumes forestry and mill residue the plant also functions as a disposal outlet for the region's timber industry.
Source
Grayling Generating 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 NorthStar Clean Energy project page for Grayling Generating Station, Atlantic Power project page for Grayling, Michigan and Global Energy Monitor entry for Grayling power station. 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. Wood waste-fueled power generator; long-term PPA with Consumers Energy plus a reduced dispatch agreement and an operating/management contract. Partnership interest, not stock, so 'shares' is null. Value not individually disclosed; see the combined 'Investments' balance note on the T.E.S. Filer City row above, which covers this investee too. 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 Grayling Generating Station Limited Partnership where a holder stated one, and are missing where no holder did.
