Overview
- Copenhagen Infrastructure Partners, through its Growth Markets Fund II, issued a final notice to proceed and started building the Patache battery project under its main contracts.
- The utility-scale system provides 300MW of power with 1,500MWh of storage and sits near transmission lines and heavy industry in northern Chile.
- The battery will store excess solar by day and feed the grid at peak to cut CO2, and the project has qualified for an internationally recognized carbon-offset program.
- CIP says Patache applies lessons from its Arena battery in Antofagasta, which is now operating and delivering power to the grid.
- Industry group ACERA reports storage kept curtailment from reaching 8TWh in 2025 and forecasts about 9GW of four-hour batteries online in Chile by the end of 2026.
