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.
