US$300M IFC financing backs Central Puerto’s storage and hydro plans.

Central Puerto S.A. has entered into a financing agreement with the International Finance Corporation for US$ 300,000,000. The company states that the funds are earmarked to install 150 MW of battery energy storage systems in the Buenos Aires metropolitan area and to support the acquisition, operation, and maintenance of the 1,440 MW Piedra del Águila Hydroelectric Power Plant.

This structure links long-term capital from a multilateral lender directly to specific generation and storage projects, which are clearly identified by capacity in megawatts. It suggests a focus on both grid stability through storage and ongoing operations of a large hydro facility, though detailed terms such as maturity, pricing, or security are not described in the excerpt.

Future company communications and periodic reports may provide more detail on deployment timing of the 150 MW battery systems and the financial performance of the Piedra del Águila concession over upcoming reporting periods.
