RGreen Invest secures €900 million for fifth energy transition fund amid fierce European competition

Paris-based RGreen Invest has closed its fifth energy transition equity fund at €900 million, marking a sizeable step up from the €670 million final close of its previous Infragreen vehicle in 2021. According to the announcement by the manager, Infragreen V was launched in summer 2023 with an initial target in the €800 million–€1 billion range and is structured as an Article 9 product under SFDR.

RGreen said the fundraising took longer than anticipated amid challenging market conditions and heightened competition from larger generalist managers moving into the European energy transition space. “It was hard to fight against huge generalist funds or big funds, but in the end we’ve done well,” Stéphanie Bégué, managing partner at RGreen Invest, told Infrastructure Investor. She also pointed to strong retention among existing backers, saying the fund achieved “an 80 percent re-up rate [from the previous fund], which is good after the period of time we crossed.”

Infragreen V follows the same core strategy as its predecessors, targeting equity and quasi-equity stakes in mid-market projects across generation, storage and electrification, while avoiding subsidy-dependent and high-technology-risk assets. Bégué said the fund concentrates energy production investments where power prices are elevated, aiming “to produce green electrons at a very low price.” The vehicle targets double-digit returns over a ten-year investment horizon.

The manager has already deployed roughly 70 percent of Infragreen V’s capital and expects the vehicle to be fully allocated by year-end, the firm said. Early portfolio entries include French energy storage player NW Storm, Vienna-based independent power producer Renalfa IPP and Italian biomethane developer Belenergia.

RGreen’s broader platform and recent activity underline its multi-strategy approach across equity and debt. The firm manages the Infrabridge short-term senior debt series, which has financed hundreds of megawatts for developers, and in February 2025 partnered with Echosys Invest to close a €100 million Afrigreen Debt Impact Fund aimed at commercial, industrial and small utility solar in Africa. In September 2025 the firm’s infrastructure debt arm provided senior bridge financing for the conversion of biogas plants into high-efficiency biomethane units in northern Italy, and RGreen later sold its 50 percent stake in the Italian solar platform GDS Italia to Générale du Solaire.

Institutional demand for Infragreen V came from a mixed pool of French and wider European investors, the manager said, naming the French Pension Reserve Fund, the European Investment Fund and several large insurers among backers. Around half of limited partners in the new vehicle are reported to be new to RGreen, and 30–40 percent of LPs come from outside France. RGreen Invest manages approximately €3.4 billion of assets.

Industry data and recent fundraising trends show that mid-market infrastructure managers are spending more time on the road; Infrastructure Investor’s 2025 fundraising report notes a two‑year cycle has become common. Bégué’s comments and RGreen’s outcome reflect those pressures while signalling that specialised managers can still secure substantial backing by emphasising sector expertise and pipeline delivery.

RGreen’s stated preference for markets such as Italy and parts of Eastern Europe, together with a recent easing in capital expenditure for European developers driven by shifts in global supply dynamics, has been cited by the firm as supportive for deployment and value creation. The company framed its approach as prioritising predictable, lower‑risk technologies and merchant exposures where unit economics allow competitively priced clean power production.
