Who owns LUMA Energy, LLC
One company in the researched set discloses a stake in LUMA Energy, LLC, none of it sized by anyone who discloses it. LUMA Energy, LLC 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.

LUMA Energy, LLC operates and maintains the electricity transmission and distribution network of Puerto Rico. It was set up in January 2020 as a fifty fifty venture between Quanta Services of Houston and Canadian Utilities, part of ATCO of Calgary, to bid for the work put out by the Puerto Rico Public-Private Partnership Authority after Hurricane Maria exposed the state of the grid. It won a 15 year operation and maintenance agreement with the Puerto Rico Electric Power Authority worth about 1.5 billion dollars, signed in June 2020, and took over the system on 1 June 2021. LUMA runs, repairs, bills for and is meant to modernise more than 18,000 miles of transmission and distribution lines serving roughly 1.5 million customers, but it owns none of the assets and does not run any power stations, which stay with the public authority and separate generation operators. Its performance has been contested throughout, with island wide outages and repeated political moves to end the contract.
Source
LUMA Energy, LLC 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 Quanta-ATCO joint venture LUMA Energy commences operation and maintenance of Puerto Rico's electric power transmission and distribution system (Quanta Services), Luma Energy (Wikipedia) and LUMA (ATCO). 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.
- Quanta Services, Inc.. Quanta's FY2025 10-K states its portion of earnings from unconsolidated integral affiliates 'includes, among others, our 50% equity interest in LUMA Energy, LLC (LUMA), a joint venture that was selected to operate, maintain, and modernize the approximately 18,000-mile electric transmission and distribution system in Puerto Rico.' LUMA is accounted for as an equity method investment and is an integral unconsolidated affiliate (not consolidated). Neither the FY2025 10-K nor the Q2 2026 10-Q discloses a LUMA-specific carrying value: both report only a combined 'equity method investments, integral unconsolidated affiliates' balance of $283.262 million at 30 Jun 2026 ($265.094 million at 31 Dec 2025) that covers LUMA together with two other unnamed integral affiliates (see the other two holding rows below), so value_usd is null here per the brief's rule against assigning a combined balance to one investee. A 50% interest in an LLC is not a share count, so shares stays null. 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 LUMA Energy, LLC where a holder stated one, and are missing where no holder did.
