## Relationship to the Yorktown platform
The fund sits inside the Yorktown Partners platform, a New York private equity firm founded in 1997 that specializes in energy-focused investments across the United States.[3](https://www.privateequityinternational.com/institution-profiles/yorktown-partners.html) According to the firm's own statements, Yorktown has raised over $8 billion of capital commitments across thirteen partnerships since 1991 and provided financing and leadership to over 90 companies in the energy industry.[5](https://www.encapinvestments.com/news/us-grid-company-secures-investment-backing-encap-investments-lp-and-yorktown-partners)
The renewable infrastructure fund is linked to the older Yorktown Energy Partners series by two markers visible in the filings: the shared filing address at 410 Park Avenue and the same related persons on the Form D.[1](https://www.sec.gov/Archives/edgar/data/1801461/000180146120000001/0001801461-20-000001-index.html) • [2](https://13f.info/form-d/0001801461-yorktown-renewable-energy-infrastructure-fund-l-p)
## People
The Form D names seven related persons: Robert A Signorino, W Howard Keenan, Bryan H Lawrence, Tomas R LaCosta, Peter A Leidel, Bryan R Lawrence, and James C Crain.[2](https://13f.info/form-d/0001801461-yorktown-renewable-energy-infrastructure-fund-l-p) Peter Leidel is listed by Private Equity International as a founding partner of Yorktown Partners and Bob Signorino as chief financial officer.[3](https://www.privateequityinternational.com/institution-profiles/yorktown-partners.html) Directory aggregation of Form D role filings from 2011 to 2026 (unverified) shows Bryan Lawrence with 37 filings across 4 firms.[4](https://aum13f.com/firm/yorktown-partners-llc) In 2026, [Bryan H. Lawrence](https://www.edgepedia.org/bryan-h-lawrence) signed the Yorktown Energy Partners IX 13F as managing member of the general partner's general partner.[6](https://www.sec.gov/Archives/edgar/data/1503466/000114036126005795/0001140361-26-005795.txt)
The sources do not describe the individual track records these partners brought to the renewable vehicle beyond their shared Yorktown platform history.
## The 2020 fund, by the numbers
The fund's Form D was filed on January 31, 2020, reporting $125,000,000 total sold, with the first sale on January 16, 2020 and an indefinite total offering amount.[2](https://13f.info/form-d/0001801461-yorktown-renewable-energy-infrastructure-fund-l-p) • [1](https://www.sec.gov/Archives/edgar/data/1801461/000180146120000001/0001801461-20-000001-index.html) The filing claims exemptions under Rule 506(b) and Investment Company Act sections 3(c)(1) and 3(c)(7), the 3(c)(7) exemption indicating the fund is offered to qualified purchasers.[1](https://www.sec.gov/Archives/edgar/data/1801461/000180146120000001/0001801461-20-000001-index.html) • [4](https://aum13f.com/firm/yorktown-partners-llc)
A later amendment reported fund AUM of $34.3 million as of March 31, 2021 (unverified, directory source), against the $125.0 million sold, a gap the sources do not explain; it may reflect capital not yet drawn, but no source states why.[4](https://aum13f.com/firm/yorktown-partners-llc) Within the same manager's family of vehicles, the renewable fund sits among the smaller ones: Yorktown Midstream Partners LP is reported with $138.2 million sold and $206.0 million AUM (unverified, directory source).[4](https://aum13f.com/firm/yorktown-partners-llc) The evidence does not include peer energy-transition infrastructure funds, so no like-for-like size comparison is possible.
## Strategy and portfolio
The Form D classifies the fund as a venture capital fund in the pooled investment fund industry, based in New York.[2](https://13f.info/form-d/0001801461-yorktown-renewable-energy-infrastructure-fund-l-p) The sources do not detail stage, check size, geography, or the split between venture-style bets and yield assets.
The one publicly identified investment is the announcement carried on EnCap Investments' newsroom: Yorktown Partners backed **US Grid Company (USGRDCO)** alongside EnCap Investments to acquire and manage critical electric generation assets in major US cities, using large-scale battery storage and renewable energy projects to decarbonize the grid.[5](https://www.encapinvestments.com/news/us-grid-company-secures-investment-backing-encap-investments-lp-and-yorktown-partners) This is the sponsors' own announcement, not independent reporting, and the sources do not attribute the deal to the 2020 fund specifically. Independent portfolio reporting is otherwise thin: no verified list of the fund's portfolio companies, exits, or write-downs exists in the evidence.
## Recent developments
