Across these 50 “Venture - Series Unknown” energy rounds (most recent date 2025-11-27 at Syspetro, undisclosed; oldest 2022-06-21 at Kuva Systems and Steelhead Composites, each $9M and $5M), the disclosed amounts show a wide spread: the largest disclosed round is EnergyX at $450M on 2022-07-15, which dwarfs the next-largest disclosed amounts ($450M also appears for Electrify America on 2022-06-28). Below that top tier, multiple companies cluster in the tens-of-millions range—for example Highview Power ($171M, 2025-11-11), Electra ($167M, 2022-07-01), and Sunly ($193M, 2022-10-13).
Geographically and temporally, there’s a pronounced late-window cadence: 5 disclosed/undisclosed entries fall between 2025-11-02 and 2025-11-18 (including Empact at $116M on 2025-11-02 and EnTouch Controls at $50M on 2025-09-16), while earlier years (2022) contain many of the mega-rounds and mid-sized financings. The list is heavily “Series Unknown” by label (all 50 rows) and includes 6 undisclosed amounts (Syspetro 2025-11-27, Moment Energy 2025-11-05, Sinohydo 2025-09-19, Qair 2022-10-05, SEaB Energy 2022-09-01, Uptime Analytics 2022-09-01, EINHUNDERT Energy 2022-08-16), with the smallest disclosed amount at Kitekraft $1M on 2022-07-14.

Frequently asked
What stands out at the top end for disclosed funding, and how concentrated is it?
EnergyX ($450M on 2022-07-15) and Electrify America ($450M on 2022-06-28) tie for the largest disclosed round, and that level sits well above the next-largest disclosed amounts such as Yellow Door Energy ($400M, 2022-10-12) and Lunar Energy ($300M, 2022-08-24).
How do the smallest disclosed rounds compare to the rest of the list?
The smallest disclosed amount is Kitekraft at $1M (2022-07-14), with several other low prints in the $2M–$10M band such as Delta Green ($2M, 2025-10-14) and Barghest Building Performance ($2M, 2022-09-13).
Are there visible recency clusters where multiple rounds landed close together?
Yes: within about two weeks in late 2025 there are several entries, including Empact ($116M on 2025-11-02), Highview Power ($171M on 2025-11-11), and Syspetro (undisclosed on 2025-11-27), alongside other near-dated rounds like Moment Energy (undisclosed, 2025-11-05).
Which cities show repeated presence, or is the list mostly singletons by location?
Most locations appear once—for example, Raleigh-level repetition is not visible—while the dataset does include multi-country dispersion (e.g., London appears for Highview Power 2025-11-11 and Tesseract 2022-09-07, and for SEaB Energy 2022-09-01 as undisclosed).
How much of the list is “undisclosed,” and does that affect comparisons of outliers?
Undisclosed amounts appear in multiple rows (e.g., Syspetro on 2025-11-27; Moment Energy on 2025-11-05; Sinohydo on 2025-09-19; Qair on 2022-10-05; SEaB Energy and Uptime Analytics on 2022-09-01; EINHUNDERT Energy on 2022-08-16). The top-tier outlier comparisons still hold because the largest disclosed amount is explicitly $450M for EnergyX and Electrify America.
Does the stage labeling look uniform, or are there mixed stage formats within “Energy” here?
All 50 entries use the same stage label “Venture - Series Unknown,” so the stage mix is uniform; the main variance is in disclosed amounts, ranging from Kitekraft’s $1M (2022-07-14) up to the $450M top tier (EnergyX and Electrify America).
