Spanish IPP Sonnedix has signed three power purchase agreements (PPAs) for its 117MW/643.8MWh Sonnedix Librillo battery energy storage system (BESS) project in Chile.
The PPAs were signed with Copec EMOAC, the Chilean, renewables-focused subsidiary of mining and forestry group COPEC.
Sonnedix said the partnership will allow Copec EMOAC to integrate nighttime energy into its portfolio through the discharge of the Librillo BESS.
The company also said the agreement represents a significant step in the consolidation of long-term contracts linked to renewable energy and storage in Chile. It includes supply at the Francisco node, in the north of the country, and incorporates substantial storage capacity through BESS, helping to enable optimised solar energy management and mitigating its variability.

Battery energy storage deployment is rapidly expanding in Chile. Based on current trajectories, Chilean renewable energy and storage association ACERA, forecasts that roughly 9GW of BESS capacity, with an average duration of 4 hours, will be online by the close of 2026, achieving the nation’s 2030 target of 2GW four years early.
Central Oasis represents Grenergy’s second gigawatt-hour-scale hybrid project in the country, following the Oasis de Atacama development in Chile’s Atacama Desert region. The two together will total around 15GWh of BESS once fully built out.
Earlier this month, Denmark-based Copenhagen Infrastructure Partners (CIP) began construction on the 300MW/1,500MWh Patache BESS in northern Chile.
CIP claimed that Patache is “strategically located in an area with world class solar resource”, sited adjacent to existing transmission infrastructure and energy intensive industrial clusters.
In 2023, Nine projects, totalling over 2GWh of capacity, and pairing solar or wind with energy storage submitted environmental impact assessments (EIAs) in Chile, by companies including Engie, EDF and Sonnedix.
Sonnedix submitted the Carica Wind Park, a project that included a 92MW/400MWh BESS, with a commercial operation date of 2027 and an investment of US$290 million.
