Sonnedix, Copec EMOAC Sign PPAs for Chilean BESS Project

Why It Matters

The PPAs accelerate Chile’s transition to a more resilient, low‑carbon grid by unlocking storage for intermittent renewables, while positioning Sonnedix as a leading storage provider in Latin America.

Key Takeaways

• Sonnedix signs three PPAs with Copec EMOAC for 117 MW BESS.
• Librillo BESS will deliver 643.8 MWh, operating 5 hours daily.
• Commercial operation slated for April 2027, enhancing Chile’s grid flexibility.
• Project supports nighttime renewable integration, reducing curtailment.
• Sonnedix now manages 1 GW in Chile, 1.8 GW pipeline.

Pulse Analysis

Chile’s rapid expansion of solar and wind generation has outpaced the grid’s ability to absorb variable output, prompting utilities and corporates to seek storage solutions that can shift power to periods of low generation. Battery energy storage systems (BESS) like the 117 MW Librillo project provide a dispatchable resource that smooths supply curves, mitigates curtailment, and enhances overall system reliability. By delivering 643.8 MWh over a five‑hour window each day, the facility will enable Copec EMOAC to tap nighttime renewable energy that would otherwise be wasted.

The partnership between Sonnedix and Copec EMOAC underscores a broader trend of corporate buyers locking in long‑term renewable contracts that include storage components. Copec EMOAC’s PPAs give it firm access to clean energy at predictable prices, while Sonnedix leverages its expertise in hybrid projects to diversify revenue streams beyond solar and wind alone. The integration at the Francisco node will improve solar output management in the Antofagasta region, reducing volatility and supporting the country’s goal of achieving 70% renewable electricity by 2030.

Regionally, the Librillo BESS signals growing investor confidence in Latin America’s storage market, where projects are still a fraction of global capacity. As more developers replicate Sonnedix’s model—pairing large‑scale batteries with existing renewable assets—grid operators can expect smoother dispatch, lower balancing costs, and a faster path to decarbonisation. The anticipated 2027 commercial start date positions the project to capture early market share, set performance benchmarks, and catalyse further financing for the continent’s next wave of energy‑storage investments.
