Who owns Bangkok Cogeneration Company Limited
One company in the researched set discloses a stake in Bangkok Cogeneration Company Limited, none of it sized by anyone who discloses it. Bangkok Cogeneration Company Limited is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Bangkok Cogeneration runs natural gas fired combined cycle cogeneration plants in the Map Ta Phut Industrial Estate in Rayong province, Thailand, producing electricity and process steam at the same time. It was set up in 1995 under Thailand's Small Power Producer scheme by Air Products Investment B.V. alongside Thai shareholders including Huakee Paper, Chatubut Holding and Bangkok Industrial Gas. Its first plant has an installed capacity of 112 megawatts, and a second plant was built with an initial 162 megawatts and a further 89 megawatt phase, covered by a 25 year power purchase agreement signed with the Electricity Generating Authority of Thailand in 2020. Power and steam go to the national grid and to industrial customers on the estate.
Source
Bangkok Cogeneration Company Limited 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 Bangkok Cogeneration Co., Ltd. company website, Air Products and Chemicals, Inc. Exhibit 21.1 subsidiaries list (SEC EDGAR) and Bangkok Cogeneration Co Ltd company profile (Bloomberg). 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.
- Air Products and Chemicals, Inc.. Foreign industrial gas/cogeneration producer in Thailand, accounted for under the equity method. Part of the combined equity affiliates balance; no individually disclosed value. source
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 Bangkok Cogeneration Company Limited where a holder stated one, and are missing where no holder did.
