Energy storage and EV infrastructure solutions firm NHOA has commissioned a 31MWh battery energy storage system (BESS) in Peru for multinational utility and IPP Engie.

The BESS unit was provided by NHOA to Engie Energía Perú on a turnkey basis and has been deployed at Engie’s 800MW ChilcaUno thermoelectric power plant, in Chilca, on the coast near the capital Lima.

It was inaugurated on 15 September in a ceremony attended by the Peruvian Minister of Energy Oscar Vera, the Vice-Minister of Energy Jaime Lu and the French Ambassador to Peru, H.E. Marc Giacomini. Engie is headquartered in Paris while NHOA is primarily based in Italy, though active globally.

When Engie announced the ChilcaUno BESS project last year, it said it would both help the plant operate at full capacity while also providing primary frequency regulation services to the electricity grid in Peru.

Luca Roccia, VP Americas for NHOA, commented: “We are exceptionally proud to have successfully completed this iconic project, especially considering the unprecedented challenges posed by the global macroeconomic and geopolitical environment.”

It is likely to be among the largest, if not the largest, BESS in the country. Another multinational utility and independent power producer (IPP), Italy-headquartered Enel, brought a 14.6MW BESS online at its Ventanilla thermal power plant in Callao online in 2021. Enel then described it as the country’s “first large-capacity battery system”.

Engie’s announcement comes two months after Canada-based stock market-quoted developer Polaris Renewable Energy announced it was launching a battery storage project in Peru, although gave no additional details and did not respond to a request from Energy-Storage.news when asked to do so.
