Grouped from Form D issuer names (generation, sleeve, jurisdiction and legal-form tokens removed); a name-only match, so abbreviated or renamed vehicles can be missed. Sold and investor figures are each vehicle's latest Form D; sleeves that report the same figure share one family-wide total and are counted once. Performance lines are what a public pension plan reports for its own interest in that fund, net, on the plan's cash flows and valuation date; they are not the general partner's figures.

Questions About CLEAN ENERGY FUND, L.P.
Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.
What is CLEAN ENERGY FUND, L.P.?
CLEAN ENERGY FUND, L.P. is a Delaware limited partnership that filed a Form D with the SEC on September 11, 2026 as a other investment fund. The filing claims Rule 506(b), Section 3(c), Section 3(c)(7) for an offering of pooled investment fund interests.
Is CLEAN ENERGY FUND, L.P. legit?
AltStreet does not rate legitimacy; it reports the public record. CLEAN ENERGY FUND, L.P. filed a Form D with the SEC on September 11, 2026 claiming Rule 506(b), Section 3(c), Section 3(c)(7). A Form D is a notice of an exempt offering, not a review or approval of it. The newest notice reports $449,666,440 sold to 37 investors. AltStreet's enforcement record (SEC, FINRA and state actions) shows no action naming the issuer as of today. Before investing, confirm the filing on EDGAR, check the seller's registration on FINRA BrokerCheck, and read the offering documents, which a Form D does not include.
Is CLEAN ENERGY FUND, L.P. registered with or approved by the SEC?
No. A Form D is a notice that an issuer is selling securities under an exemption from registration, and the SEC does not review, approve, or pass on the merits of the offering. The filing shows that CLEAN ENERGY FUND, L.P. claimed Rule 506(b), Section 3(c), Section 3(c)(7) and disclosed the items the form requires, such as the amount sold, the minimum investment, related persons, and anyone paid to sell the securities. It does not verify the issuer's claims or its business.
How much has CLEAN ENERGY FUND, L.P. raised?
CLEAN ENERGY FUND, L.P. reported $449,666,440 sold from 37 investors in an offering of indefinite size as of the Form D filed September 11, 2026.
Who can invest in CLEAN ENERGY FUND, L.P.?
The offering relies on Rule 506(b), which permits sales to accredited investors and to no more than 35 non-accredited investors who meet a sophistication standard, and prohibits general solicitation. Because the fund also relies on Section 3(c)(7), each investor must be a qualified purchaser, generally an individual with at least $5 million in investments. The filing reports no non-accredited investors. The filing lists the minimum investment as $0, meaning no minimum was stated.
What is the minimum investment in CLEAN ENERGY FUND, L.P.?
The Form D lists the minimum investment as $0, which means the issuer did not state a minimum on the form. The offering documents, not the Form D, set the actual subscription terms.
Who is selling CLEAN ENERGY FUND, L.P. and how are they paid?
The Form D names no recipient of sales compensation, which usually means the issuer or its affiliates are placing the securities directly. Sales commissions are reported as $0 and finders' fees as $0. Form D allows these to be estimates.
Who is behind CLEAN ENERGY FUND, L.P.?
The Form D lists 5 related persons: Clean Energy Transition GP I Limited, executive officer (General Partner); Benjamin Singh, director (Director of the General Partner); Andrew Linford, director (Director of the General Partner); Charles Woolnough, director (Director of the General Partner); Clean Energy Transition LLP, promoter (Investment Adviser).
