TotalEnergies Expands LNG Partnership with AES on Renewable and Battery Storage in Caribbean

TotalEnergies announces the closing of its acquisition of a 50 percent stake in the solar, wind and Battery Energy Storage Systems (BESS) portfolio of AES Dominicana Renewables Energy.

This deal follows TotalEnergies’ 2024 acquisition of a 30 percent share in AES solar and battery assets currently under construction in Puerto Rico. The combined portfolio now exceeds 1.5 GW of renewable energy and BESS capacity across the Caribbean.

These transactions advance TotalEnergies' multi-energy strategy in a region where it is a key player in the liquefied natural gas (LNG) value chain.

AES’ renewables portfolio includes over 1 GW of contracted wind, solar, and BESS projects, of which 410 MW is already operational or under construction, supplying electricity under long-term Power Purchase Agreements (PPAs). The portfolio also includes over 500 MW of solar and wind capacity in development, alongside BESS projects, which will be integrated into solar plants to mitigate intermittency and enhance grid stability.

This acquisition will allow TotalEnergies to expand its renewables business in the Dominican Republic, where the Company already has a partially solarized network of 184 service stations, natural gas distribution and a 103 MW solar plant under construction.

The AES’ renewables portfolio includes 485 MW of contracted solar and BESS projects, comprising 200 MW of solar and 285 MW/1,140 MWh of BESS projects currently under construction.

After acquiring 30 percent of these assets in 2024, TotalEnergies is pursuing deployment of its multi-energy strategy on the island, where it is already active in the fuel, lubricants, and aviation sectors, and operates a network of 200 service stations between Puerto Rico and the island of St Thomas.

We are pleased to expand our multi-energy strategy through this partnership with AES, focusing on renewables and battery storage in a region where TotalEnergies is already a leading supplier of LNG, notably for power generation. Since 2018, we have been supplying LNG to AES’s subsidiaries in Panama and the Dominican Republic, said Stéphane Michel, President of Gas, Renewables & Power at TotalEnergies. These new transactions will contribute to our targets of 35 GW of gross renewable capacity by 2025 and over 100 TWh of electricity production by 2030.

We are excited to join forces with TotalEnergies as we diversify the island’s energy mix. The proceeds from this transaction will be reinvested in AES Dominicana, to grow our renewables footprint, said Juan Ignacio Rubiolo, AES Executive Vice President & President, Energy Infrastructure and Leader of International Markets.
