Mirova Energy Transition 6 Fund Reaches €1.2 Billion at Second Close
November 13, 2025
Mirova, an affiliate of Natixis Investment Managers dedicated to sustainable finance, is pleased to announce that its flagship energy transition fund, Mirova Energy Transition 6 (MET6)1, successfully held its second close in August 2025, reaching €1.2 billion in commitments. This milestone was achieved thanks to strong support from both returning investors and new partners.
With 10 investments totaling more than €960 million, circa half of MET6 target size, in committed capital, MET6 has already deployed nearly half of its target fund size, confirming the fund’s rapid pace of execution. MET6 portfolio is reflective of the fund’s strategy with one third invested in large renewable portfolios in three geographies, half of the commitments dedicated to the growth of three Independent Power Producers with extensive track record and the rest in the e-mobility space.
Over the past year, the team has screened more than 300 opportunities, representing €18 billion in equity and over 190 GW of installed capacity. The pipeline remains robust, with several projects in advanced discussions expected to close by year-end. These opportunities reflect MET6’s strategic focus on sector and geographic diversification.
MET6 invests in greenfield, brownfield and corporate infrastructure across OECD countries. Target sectors include renewable energy production (solar photovoltaic, onshore wind, hydropower), energy storage, low-carbon mobility and energy efficiency.
With a target fund size of €2 billion, Mirova will continue its fundraising efforts throughout 2025.
“The successful second close of MET6 marks a pivotal moment in our journey to accelerate the energy transition. Institutional investors continue to show strong appetite for energy transition infrastructure, drawn by its potential to deliver stable, long-term returns while aligning with global decarbonization goals. The asset class stands out for its resilience, depth, and capacity to generate predictable cash flows, especially in a volatile macroeconomic environment.”
