Among the 25 most recent energy funding entries shown, the largest disclosed round is Mainstream Renewable Power’s $271M (2025-04-03), and it dwarfs the next-largest disclosed amounts: Amarenco’s $212M (2025-04-15) and Greenlink Interconnector’s $200M (2026-06-16). Most other disclosed rounds cluster far lower, including multiple entries in the ~$20M–$60M range (for example, Revolve Renewable Power at $40M in 2026-02-05 and Xerotech at $49M in 2024-09-06), while several small disclosed rounds sit below $5M (e.g., Clontarf Energy $600K on 2024-09-25 and Barryroe Offshore Energy $1M on 2023-10-02).
Date and geography also cluster. Revolve Renewable Power ($40M on 2026-02-05), Greenlink Interconnector ($200M on 2026-06-16), and AeroBeam ($60K on 2026-06-25) anchor the most recent period, while a dense April 2025 window includes XFuel ($5M on 2026-05-27) outside it but does include Mainstream Renewable Power ($271M on 2025-04-03), Amarenco ($212M on 2025-04-15), and WElink Group ($22M on 2024-05-13 is not in the same month) plus broader spring 2025 activity like Urban Volt ($45M on 2025-05-02). Dublin-based entries recur frequently (e.g., Greenlink Interconnector in Saggart, Revolve Renewable Power in Dublin, and Greencoat Renewables in Dublin), with other counties appearing as well (Cork, Galway, Limerick, and Westmeath).

Frequently asked
What stands out as the largest disclosed round, and how does it compare to the rest of the table?
Mainstream Renewable Power’s $271M (2025-04-03) is the largest disclosed amount in the 25 rows. It sits well above the next-largest disclosed rounds shown, including Amarenco at $212M (2025-04-15) and Greenlink Interconnector at $200M (2026-06-16).
Are there outlier entries that are much smaller or have missing disclosed amounts?
Yes: AeroBeam is a low outlier at $60K (2026-06-25), far below most other disclosed rounds like Revolve Renewable Power’s $40M (2026-02-05) and Xerotech’s $49M (2024-09-06). There are also two non-disclosed entries: TechMet (undisclosed on 2026-01-09) and BHSL (undisclosed on 2022-04-20), which prevent direct comparisons against the disclosed distribution.
Which stage classifications dominate, and what share of rows lack a specified amount?
Within the rows shown, “Series Unknown” appears in most entries (22 of 25), while other labels include Private Equity (BHSL, 2022-04-20) and Post-IPO Equity (Greencoat Renewables, $311M on 2022-04-01). Two rows show “undisclosed” amounts (TechMet on 2026-01-09; BHSL on 2022-04-20), and one row lacks a stage label entirely (Fincovi on 2020-04-03, $700K with a blank stage field).
Is there a temporal cluster in the most recent years or a long run-up across the window shown?
The table spans from 2020-04-03 (Fincovi, $700K) to a latest date of 2026-06-25 (AeroBeam, $60K). In addition to the most recent mid/late-2026 activity (AeroBeam on 2026-06-25; Greenlink Interconnector on 2026-06-16; XFuel on 2026-05-27), there is also concentrated funding around spring 2025, including Mainstream Renewable Power ($271M on 2025-04-03), Amarenco ($212M on 2025-04-15), and Urban Volt ($45M on 2025-05-02).
Does geography cluster around Dublin, or are other counties equally represented?
Dublin-area locations recur repeatedly: Greenlink Interconnector is listed in Saggart, Dublin; Revolve Renewable Power and Urban Volt are listed in Dublin; and Greencoat Renewables is listed in Dublin (2022-04-01). Other counties appear but less frequently, including Cork (Amarenco $212M on 2025-04-15; Simply Blue Group $29M on 2022-11-17; Eqtec $3M on 2023-09-04), Galway (ÉireComposites $4M on 2025-12-08; Xerotech $49M on 2024-09-06), and Limerick (VIOTAS $11M on 2025-05-22; BNRG Renewables is in Dublin, but BHSL is in Limerick with an undisclosed amount on 2022-04-20).
