Innergex and Prevalon Add 210MWh New Capacity to Existing Chile BESS

Why It Matters

The added storage strengthens Chile’s grid flexibility, enabling higher renewable penetration and setting a benchmark for secure, certified battery solutions in Latin America. It also positions Innergex and Prevalon as key players in a rapidly scaling market.

Key Takeaways

• San Andrés II BESS adds 42 MW/210 MWh capacity
• Combined San Andrés capacity reaches 77 MW/385 MWh
• Prevalon supplies HD 511 LFP solution with IEC 62443 Level 2
• Chile projects 9 GW BESS by 2026, ahead of 2030 target

Pulse Analysis

Innergex’s latest move in the Atacama region underscores the growing reliance on battery energy storage to balance intermittent solar generation. By linking the 42 MW/210 MWh San Andrés II BESS directly to the existing solar farm, the partnership with Prevalon delivers a seamless, dispatchable power source that can smooth daily output fluctuations. The deployment leverages Prevalon’s HD 511 liquid‑cooled lithium‑iron‑phosphate modules, which combine high energy density with robust thermal management, while the US‑engineered energy management system ensures optimal charge‑discharge cycles and grid interaction.

Chile’s energy landscape is undergoing a rapid transformation, driven by aggressive renewable targets and supportive policy frameworks. Industry association ACERA projects nearly 9 GW of battery storage to be operational by the close of 2026, a figure that dwarfs the nation’s 2 GW goal for 2030. Recent contracts by Spanish IPPs Sonnedix and Grenergy illustrate a competitive pipeline of large‑scale BESS projects, reinforcing Chile’s reputation as a testbed for advanced storage technologies. The cumulative capacity of projects like San Andrés and Salvador now exceeds 140 MW/695 MWh, illustrating how utility‑scale storage is becoming integral to meeting demand peaks and providing ancillary services.

For investors and market observers, the Innergex‑Prevalon collaboration signals confidence in the commercial viability of certified, cyber‑secure storage solutions. The adherence to IEC 62443‑5‑1 Level 2 cybersecurity and UL safety standards mitigates operational risk, a critical factor as grid operators demand higher reliability. As global capital flows increasingly target green infrastructure, the successful energisation of San Andrés II positions both companies to capture further contracts across Latin America, where similar regulatory incentives and renewable growth trajectories are emerging.
