Across the 42 most recent funded energy startups listed for San Francisco, the largest disclosed round is Gridware’s $1.2B (Generate Capital is listed at $1.2B) on 2024-11-20, which dwarfs the next-largest disclosed amounts such as Recurrent Energy’s $161M (2023-06-06) and Geofy’s $150M (2025-02-20). The smallest disclosed amount is Hydro Wind Energy’s $80K (2025-02-12), making the disclosed range unusually wide even before including the many undisclosed figures.
The dates span 2020-10-07 (Redaptive) through 2025-11-23 (Gridware), with a visible concentration in 2023–2024 where multiple large checks appear (e.g., Recurrent Energy $161M on 2023-06-06; Span.IO $84M on 2023-03-03; Patch Technologies $55M on 2022-09-13 and OhmConnect $55M on 2022-06-09). Stage classification is also heavily uneven: 20 of 42 rows are labeled “Series Unknown” and 4 of 42 rows are explicitly “undisclosed,” while several rounds carry concrete stages (e.g., multiple Series A/B/C, plus early-stage Pre-Seed and Seed).

Frequently asked
What’s the largest disclosed round in this San Francisco energy list, and how extreme is it versus the rest?
The top disclosed amount is Generate Capital’s $1.2B on 2024-11-20, with the next-largest disclosed figures far lower (e.g., Geofy at $150M on 2025-02-20 and Recurrent Energy at $161M on 2023-06-06). Even well-known mid-to-large rounds like Patch Technologies’ $55M (2022-09-13) and OhmConnect’s $55M (2022-06-09) sit below that top outlier.
How much of the list clusters in the most recent time window, and what does that look like by dates?
The most recent entry is Gridware on 2025-11-23 ($55M), and several other disclosures land in 2025 before the year ends (e.g., Renewable Properties $36M on 2025-05-05; Equilibrium Energy $28M on 2025-03-12; Tyba $14M on 2025-02-06). Earlier years still matter, with the earliest dated row in the set at 2020-10-07 (Redaptive, $157M).
Are “Series Unknown” and “undisclosed” common here, and what share of the 42 rows does that represent?
Yes. “Series Unknown” appears in 20 of 42 rows (e.g., Geofy $150M on 2025-02-20; Recurrent Energy $161M on 2023-06-06), while “undisclosed” appears in 4 of 42 rows (e.g., Aether Fuels on 2025-08-11; Carbon Free Energy Cloud on 2023-02-07; Project Vesta on 2022-11-01).
Which stage labels show up as meaningful anchors compared with early-stage entries?
Concrete stages recur: Series A appears on Tyba ($14M, 2025-02-06), GlacierGrid ($5M, 2024-10-04), and Verse ($21M, 2024-05-22), while Seed and Pre-Seed also recur (e.g., Jupe Seed $1M on 2025-04-01; Nuclear Software Pre-Seed $500K on 2025-03-12; Upfront Pre-Seed $500K on 2023-04-05). In contrast, half the rows are not assigned a specific stage label because they are tagged “Series Unknown.”
Is the funding-size spread unusually large, and what are the key low and high anchors?
The disclosed range spans from a low anchor of $80K (Hydro Wind Energy on 2025-02-12) up to $1.2B (Generate Capital on 2024-11-20). That spread is reinforced by other large disclosed rounds sitting in the $100M+ range—such as Recurrent Energy at $161M (2023-06-06) and Span.IO at $84M (2023-03-03)—while several entries cluster in much smaller disclosed checks like $200K (Savion Aerospace on 2021-06-08) or $250M (Aurora Solar on 2021-05-24).
