Try Dealroom → company, to fund the expansion of its wind farm in Buenos Aires Province. The financing splits into a US$20 million tranche from IDB Invest and up to US$80 million mobilized from international lenders, with a corporate guarantee from AES Argentina.
Who's in? BBVA and FMO joined the B tranche, with FMO disclosing a US$20 million participation. Global law firm Clifford ChanceDealroom has a profile for this one. Try Dealroom → advised IDB Invest, with a team led by Washington, DC partner Fabricio Longhin.
What's the endgame? The money funds Vientos Bonaerenses III and IV in Tornquist and Bahía Blanca, adding 102.4MW of capacity. That nearly doubles the complex to 202.2MW total and is expected to produce roughly 370 GWh of additional electricity each year, sold to commercial and industrial customers.
Why now? The deal follows IDB Invest's "Originate to Share" model, in which its US$20 million tranche is designed to mobilize long-term private capital for infrastructure. The electricity will be traded under Argentina's Renewable Energy Term Market (MATER), which supplies large private users rather than relying on subsidized state procurement.
What could go wrong? The wider opportunity remains constrained by grid capacity, with recent MATER proposals flagging limited transmission headroom. The project's payoff depends partly on its ability to connect and deliver reliably.
The signal: The round stands out less for its size than for its structure — a concrete example of private capital backing market-based renewables in Argentina. As the country diversifies its energy matrix and leans on private offtake, deals like this test whether multilateral lenders can crowd in foreign financing at scale.
