Energy funding in Washington (11 most recent entries shown) is split between a single, dominant outlier and a long tail of smaller rounds. Venture Global LNG’s $1.3B debt financing on 2021-11-22 dwarfs the next-largest disclosed amounts, with the largest non-outlier shown being Sol Systems’ $675M on 2025-07-16; everything else in the table ranges from $200M down to $100K.
The entries also cluster tightly by geography and timing: all 11 rows list Washington, District of Columbia, United States, and 5 of the 11 rounds (C-Quest Capital $150M on 2023-04-12; ARC Clean Energy $7M on 2023-10-26; Emerald Cities Collaborative $730K on 2023-06-13; Arcadia $200M on 2022-05-10; SparkMeter $10M on 2022-03-24) fall between 2022 and 2023.

Frequently asked
Which disclosed round is the clear outlier in Washington energy funding, and how does it compare to the next-largest?
Venture Global LNG’s $1.3B debt financing (2021-11-22) is far above the rest of the disclosed amounts. The next-largest disclosed round is Sol Systems at $675M (2025-07-16), making the 2021 outlier roughly “in a different tier” versus every other entry shown.
How concentrated are rounds temporally within the date range covered by this list?
Across the 11 rows (from 2021-11-22 to 2025-07-16), there’s a notable mid-window cluster: 5 entries fall in 2022–2023 (SparkMeter $10M on 2022-03-24; Arcadia $200M on 2022-05-10; GreenMet $100K on 2022-03-17; Emerald Cities Collaborative $730K on 2023-06-13; ARC Clean Energy $7M on 2023-10-26). Earlier (2021) is limited to Venture Global LNG, and later activity shows up most clearly in 2024–2025 via Curio ($8M on 2024-04-18), Nithio Holdings ($10M on 2024-01-25), and Sol Systems ($675M on 2025-07-16).
Are there over-represented stage labels among these Washington energy startups?
Yes. “Series Unknown” appears in 5 of 11 rows, including Sol Systems (2025-07-16, $675M), Nithio Holdings (2024-01-25, $10M), ARC Clean Energy (2023-10-26, $7M), Emerald Cities Collaborative (2023-06-13, $730K), and C-Quest Capital (2023-04-12, $150M). The explicitly labeled stages are fewer: one “Series B” (Zeno Power, 2025-05-14, $50M), one “Seed” (Curio, 2024-04-18, $8M), one “Series E” (Arcadia, 2022-05-10, $200M), one corporate round (GreenMet, 2022-03-17, $100K), and one debt financing (Venture Global LNG, 2021-11-22, $1.3B).
Do any specific rounds or companies sit unusually low compared with the rest of the disclosed amounts?
GreenMet’s $100K corporate round (2022-03-17) is the smallest disclosed amount in the list. That $100K figure sits below the next-smallest disclosed entry, Emerald Cities Collaborative at $730K (2023-06-13), and is far below the mid-single-digit-to-tens-of-millions range shown for ARC Clean Energy ($7M on 2023-10-26) and Curio ($8M on 2024-04-18).
Is the geography truly concentrated within Washington, or are there multiple city listings under this label?
All 11 entries list the same location format: Washington, District of Columbia, United States. There are no alternate city/metro strings shown in the rows (e.g., no additional Washington-area cities), so the concentration is complete within the displayed dataset.
