Abu Dhabi’s Mubadala Investment Company is partnering with UK private equity company Actis to invest €300 million ($352 million) in Rezolv Energy, a Romania-based clean energy producer.
The investment will help Rezolv Energy to accelerate its growth and become a market-leading renewable energy developer in Central and Eastern Europe, according to a press statement.
Mubadala first acquired an undisclosed stake in Rezolv through a joint venture with Actis in September 2025.
Since its investment, Rezolv Energy has 750 megawatts (MW) of renewable energy projects under construction in Romania and Bulgaria, and an additional 1.5 gigawatts (GW) of project pipeline in advanced development.
This includes Europe’s largest solar power generation project in Dama in Romania.
The company has a total generation capacity of more than 2GW through solar and wind farms, according to its website.
The investment highlights Mubadala’s growing portfolio of renewable and clean energy companies and technologies in Europe, Asia and North America, a report by Wam said.
In 2022, Mubadala invested in Tata Power’s renewables platform in India and Skyborn Renewables, the world’s largest private offshore wind developer, the report added.
Mubadala is Abu Dhabi’s sovereign wealth fund and has more than $300 billion of assets under management.
Earlier this month it gave a rare look into how it plans to allocate capital globally, outlining an infrastructure strategy that prioritises expansion in the US and Asia while becoming more selective in Europe.
