Project Description

The proposed investment consists of a 9-year senior loan of up to USD 300 million to Central Puerto S.A. ("CEPU" or the "Company"), a longstanding client of IFC. The loan will include a US$ 50 million A Loan and US$ 250 million mobilized through B Loans and/or Parallel Loans. The use of proceeds will support CEPU’s capital expenditure plan, which includes: (i) the acquisition of the Piedra del Águila hydroelectric power plant (the HPP) on the Limay River, in Neuquen, Argentina, built between 1985 and 1993, and operated by CEPU since the beginning of operations , and (ii) the installation of a 150 MW Battery Energy Storage System (“BESS”) to be located next to CEPU’s Nuevo Puerto Thermal Powerplant in Buenos Aires (together, the “Project”). The HPP has an installed capacity of 1,440 MW. It consists of a concrete gravity dam with a maximum height of 170 meters, and a powerhouse equipped with four generating units of 360 MW each. The facility includes intakes and penstocks, a spillway, bottom outlets, and associated operational infrastructure such as access roads, a bridge, and electric power supply systems. Since commencing commercial operation, the plant has historically produced an average of 4,439 GWh per year. The Nuevo Puerto BESS will have an initial energy storage capacity of 750 MWh, enabling it to deliver 150 MW of power for 5 continuous hours. Central Puerto S.A. is a leading Argentine energy company engaged in electricity generation through thermal, hydroelectric, wind, and solar power, and is also involved in natural gas transport, distribution, and forestry activities.

Overview of IFC's Scope of Review

IFC’s review of the proposed investments included the review of technical and E&S information made available by the Company for the two assets to be financed, site visits conducted in September 2025 to operational Piedra del Aguila HPP and the location where the BESS will be installed, interviews with CEPU’s management and employees, as well as a review of publicly available information. The IFC reviewed technical, environmental, and social (E&S) due diligence documentation, including CEPU’s policies and procedures, Integrated Management System Manual, the BESS Environmental Impact Assessment, the HPP Environmental Audit, occupational health and safety statistics and procedures, human resources records and documents, and environmental monitoring data. The review also covered the HPP Technical Audit Reports of the Independent Consultants Panel for 2017, 2022, and 2025, which focused on dam maintenance, operational performance, and safety. In addition, IFC held meetings with relevant parties, including the Mayor and Tourism Secretary of Piedra del Águila, representatives from the local school, health center and nearby aquaculture enterprise. The scope of this review and associated action plan is applicable to the assets financed by IFC.
