Mirova Energy Transition 6 Fund Reaches US$1.4 Billion at Second Close

Mirova, an affiliate of Natixis Investment Managers dedicated to sustainable finance, has announced that its flagship energy transition fund, Mirova Energy Transition 6 (MET6), successfully held its second close in August 2025, reaching €1.2 billion (US$1.4 billion) in commitments.

With 10 investments amounting to over €960 million (US$1.1 billion), representing around half of its total target size, MET6 has already deployed nearly 50% of its committed capital, demonstrating a strong and accelerated investment pace. The fund’s portfolio aligns closely with its strategic focus, allocating roughly one-third to large-scale renewable energy portfolios across three regions, half to supporting the growth of three established Independent Power Producers (IPPs), and the remaining share to investments within the e-mobility sector. Over the past year, the team has evaluated more than 300 investment opportunities, totaling approximately €18 billion (US$21 billion) in equity value and representing over 190 GW of installed capacity.

MET6 focuses on greenfield, brownfield, and corporate infrastructure investments across OECD countries, targeting sectors such as renewable energy generation (including solar PV, onshore wind, and hydropower), energy storage, low-carbon mobility, and energy efficiency. With a target fund size of €2 billion (US$2.33 billion), Mirova plans to continue its fundraising efforts throughout 2025 to support these sustainable infrastructure initiatives.
