Engie and Ares Strengthen Partnership with New Solar and Storage Investments
Published · 3 min read

On March 25, 2025, Engie North America expanded its partnership with Ares Management, a leading firm in alternative asset management. This partnership involves an exciting new investment in a 900 MW solar and storage portfolio in the United States. Engie will maintain a controlling stake, continuing to manage the assets. This expansion is part of their ongoing effort to grow renewable energy in the U.S. and meet the country’s rising power demand.
Details of the Recent Transaction
The recent deal between Engie and Ares will add an additional 0.9 GW of energy capacity to their portfolio, bringing the total joint energy capacity to 3.7 GW. The deal includes solar energy projects that are already operating in key U.S. power grids like ERCOT and MISO. Engie will retain control of these projects and continue to operate and manage them. This transaction follows a deal in September 2024, where Engie sold part of a 2.7 GW portfolio across U.S. grids including ERCOT, MISO, PJM, and SPP.
- Engie retains control of the assets.
- Ares is expanding its stake in renewable energy.
Why is this important? This expansion helps Engie with its capital recycling strategy. By selling stakes in some of its projects, Engie can reinvest in new renewable energy projects, thus supporting its mission to meet the growing demand for clean energy in the U.S. The partnership with Ares allows both companies to collaborate and strengthen their position in the clean energy market.
Strategic Growth in Renewable Energy
This partnership is a win-win for both companies. Engie’s focus is on expanding renewable energy generation, while Ares brings in crucial financial support. Engie’s Chief Renewables Officer, Dave Carroll, explained how this deal is part of Engie’s efforts to meet the increasing need for clean energy:
“The addition of almost 1 GW of generation and storage shows our commitment to meeting U.S. power needs and our strategy to keep deploying clean energy solutions,” said Carroll.
This partnership ensures that renewable energy will be a key part of meeting U.S. energy demands. Engie plans to continue working with Ares to drive growth in solar and battery storage projects, aiming to increase the share of sustainable energy in the U.S. power grid.
Portfolio Components and Future Prospects
The 900 MW portfolio includes three solar projects that are already up and running in the ERCOT and MISO grids. In addition, the deal also involves a battery storage project co-located with one of the solar projects in ERCOT. This is a big step forward for solar and storage technologies, as integrating solar with battery storage allows for more efficient energy storage and better reliability for the grid.
Components of the Portfolio
- Three solar projects in ERCOT and MISO.
- One battery storage project co-located in ERCOT.
This deal represents a strong commitment from both Engie and Ares to grow their combined energy portfolio. Steve Porto, a partner at Ares, shared his thoughts:
“We are excited to expand our relationship with Engie. Seeing their operational strengths and the value in these assets has strengthened our belief in the long-term potential of this partnership,” said Porto.
The Path Ahead for Engie and Ares
This new partnership represents strong growth potential for both companies. By adding another 1 GW of generation and storage, they are positioning themselves to meet future energy needs and continue their leadership in the renewable energy sector.
The expansion is just the beginning. Both companies are likely to continue growing their joint portfolio of solar energy projects and battery storage. As they deepen their collaboration, they aim to capitalize on future opportunities in the renewable energy market.
