Among the 38 private equity–funded energy companies listed (sorted by round date desc), the largest disclosed round is Invenergy’s $3.0B on 2022-01-07, which dwarfs the rest of the disclosed amounts. The next-largest disclosed figures sit far below that peak, while multiple rounds cluster in the $300M–$775M band (e.g., Silicon Ranch $775M on 2022-01-06; Intersect Power $750M on 2022-06-28; Producers Midstream $500M on 2025-10-12; Pine Gate Renewables $500M on 2022-06-23). Undisclosed rounds also appear often (10 of 38), creating a lower-information set alongside the disclosed-size pattern.
Timing shows a clear temporal edge: the most recent round is Pike (undisclosed) on 2025-11-22, while the oldest entry in the list is Artic Green Energy’s $240M on 2021-07-26. Geographically, the list is broad, but Dallas, Texas appears repeatedly in the same segment framing (Producers Midstream on 2025-10-12; Pine Gate Renewables $500M on 2022-06-23 is Charlotte; Cardinal Midstream $300M on 2022-04-21; Aspen Midstream is listed as Dallas on 2025-09-09), suggesting a modest Midstream/utility-adjacent footprint in that metro even as companies span the US, Europe, Latin America, and South Africa.

Frequently asked
What’s the largest disclosed private equity energy round in this list, and how does it compare to the next-largest disclosed amounts?
Invenergy’s disclosed $3.0B on 2022-01-07 is an outlier at the top. The next-largest disclosed amounts are far lower (e.g., Isagen $1.5B on 2025-10-19 and Intersect Power $750M on 2022-06-28), with many other disclosed rounds clustered well below $1B.
Which cluster stands out in the disclosed-dollar range, based on the amounts shown?
A substantial share of disclosed rounds sits in the mid-to-high hundreds of millions, including $300M+ entries such as Producers Midstream ($500M, 2025-10-12), Intersect Power ($750M, 2022-06-28), Silicon Ranch ($775M, 2022-01-06), and GridServe ($242M, 2022-08-08 is closer to the lower end but still in the hundreds). Meanwhile, only a small number land in the billions (Invenergy $3.0B on 2022-01-07 and Isagen $1.5B on 2025-10-19).
How much of the list is “undisclosed,” and does that affect visibility into size comparisons?
10 of the 38 rows show undisclosed amounts, including Pike (undisclosed, 2025-11-22) and Aspen Midstream (undisclosed, 2025-09-09). As a result, size-based patterning relies on the remaining disclosed rounds, while the top-of-list timing includes several non-disclosed entries (e.g., Pike and Aspen Midstream).
What does the time window look like for these rounds, from the most recent to the oldest entries?
Rounds span from 2021-07-26 (Artic Green Energy, $240M) to 2025-11-22 (Pike, undisclosed). The most recent three dated entries are SolarSaver ($60M, 2025-11-16), Berkeley Energy Commercial Industrial Solutions (BECIS) ($20M, 2025-11-01), and Pike (undisclosed, 2025-11-22).
Are there notable geographic concentrations (cities appearing more than once), or is it broadly distributed?
The list is broadly distributed across North America, Europe, Latin America, Asia, and Africa, but Dallas, Texas shows multiple appearances in this set: Producers Midstream ($500M, 2025-10-12) and Cardinal Midstream ($300M, 2022-04-21) are both listed as Dallas, and Aspen Midstream is also listed with Dallas as its location (undisclosed, 2025-09-09).
