U.S. Independent Power Producers (IPPs) by Renewable Capacity: 86 Parent Companies Aggregated from EIA-860 Project Companies
86 parent companies of U.S. independent power producers (IPPs), each with its operating solar, wind, battery storage, hydro and geothermal capacity in MW by technology, plant and generator counts, top states, and capacity under construction and planned. Built from the U.S. EIA-860 2025 final data (generators as of 2025-12-31, released 2026-09-10): the project companies that report to EIA were linked to parents using GLEIF parent relationships, SEC Exhibit 21 subsidiary lists and cited GLEIF/SEC records, with the basis and sources for every row. The rows cover 68% (210 GW) of the 307 GW of operating renewable and storage capacity EIA classifies as IPP; 97 GW could not be linked to a parent with evidence (or belongs to excluded bank/fund owners) and is left out, and parents with under 20 MW are not rows. Rate-regulated electric utility generation is excluded.

Where the source data is published
All inputs are free: EIA-860 (U.S. Energy Information Administration, public domain, https://www.eia.gov/electricity/data/eia860/), GLEIF LEI and relationship data (CC0, https://www.gleif.org/) and SEC EDGAR filings (https://www.sec.gov/edgar). What this list adds is the linking of EIA project companies to parents with the evidence, and the aggregation.

Source data as of
EIA-860 2025 final data (released 2026-09-10; generator status as of 2025-12-31); GLEIF golden copy of 2026-10-11; SEC annual reports filed 2026-01 to 2026-04
Last verified is the date we fetched the source data and confirmed it was the latest version the publishers had released.
What this list adds to the free source data
- EIA-860 lists generators under thousands of project-company names (SPVs). This list rolls them up to the parent company the evidence reaches (one row per evidenced parent; where the evidence does not connect two related companies they stay separate rows and the notes say so), with the owner shares from EIA-860 Schedule 4 applied.
- Every row says how its project companies were linked (GLEIF Level 2 parent relationship, SEC Exhibit 21 subsidiary list, a cited GLEIF/SEC record for a brand or head-office address) with the MW per basis and the source URLs.
- Capacity split by technology (solar PV, onshore and offshore wind, batteries, hydro, pumped storage, geothermal, solar thermal), plus plant and generator counts, number of states and the five largest states.
- Development pipeline from EIA-860 proposed generators: MW under construction and MW planned, linked to the same parents.
- Parents that also own a rate-regulated utility are flagged; their utility generation is not in the totals.
- GLEIF parents known to be out of date or missing were corrected from SEC filings (Avangrid to Iberdrola, Calpine to Constellation, Brookfield Renewable's U.S. platforms Scout Clean Energy, Urban Grid, Deriva Energy and Geronimo Power to Brookfield), with the filing cited; rows whose parent LEI record is lapsed say so.
Limitations and what's not included
- Not every IPP is included: 68% of the IPP-sector operating renewable and storage capacity in EIA-860 is linked to a parent. Project companies with no GLEIF parent, no SEC Exhibit 21 listing and no cited brand/address evidence are left out (e.g. Algonquin Power Co, NRG Renew, SunStrong Management, Copia Power, KKR/GA, Erie Boulevard Hydropower). Parents with under 20 MW are not rows.
- Capacity is EIA-860 nameplate MW (AC for solar) at generators with status 'operating' at the end of 2025, times the ownership share in EIA-860 Schedule 4 (or 100% to the operator when no owner is listed). It is not net generation and not contracted capacity.
- Ownership changes after the data dates are not reflected. EIA-860 shows end-2025 owners and GLEIF shows what the entities last reported; some GLEIF parent records are old. Address and brand links (linkage_basis evidence_address / evidence_name_pattern) are weaker than entity-level links: a sold project can keep its former owner's name or reporting address in EIA-860.
- NextEra's row includes projects of XPLR Infrastructure, LP (not wholly owned by NextEra) because they report NextEra Energy Resources' address to EIA and cannot be separated with EIA data.
- parent_level shows how far up the ownership chain the evidence reaches: 56 rows are GLEIF ultimate parents, 6 SEC registrants, 24 group head companies whose own owners (often infrastructure funds) were not verified.
- IPP means EIA's 'IPP Non-CHP' and 'IPP CHP' sectors. Plants of rate-regulated utilities, cooperatives, municipal and other public power, and shares owned by investor-owned utilities or public bodies are excluded; 5 bank, investment-manager or university owners listed by EIA are excluded as not IPPs (see stats.excluded_parents).
- ISO/RTO interconnection queues are not used; the development figures come only from EIA-860 proposed generators, which cover projects that have reported to EIA, not the full queues.
- No website column: none of the sources used gives company websites (SEC submissions data has none for these registrants), and websites were not guessed.
- Organisation data only: no contact persons, e-mail addresses or phone numbers. Delivered as a CSV file.
