6 FAQs about [Large scale battery storage project financing options in Chile 2025]
How much battery storage does Chile have?
Chile has an operational installed capacity of approximately 1GW in batteries, and another 3GW is under construction. Battery storage has been largely financed by bank lending in recent years, but we believe larger projects could increase the scope for bond financing.
Are battery energy storage systems a viable alternative for Chilean power producers?
With transmission lines at overcapacity and permitting delays slowing the development of new grid infrastructure, battery energy storage systems (BESS) have surged as a profitable alternative for Chilean power producers.
How much does a battery cost in Chile?
In fact, batteries charged at nearly $0/MWh during the day in the sunny, northern desert regions of Chile, sell energy at night for over $100/MWh. Although projects such as Engie’s BESS Coya are already enjoying these large spreads, this capacity payment will partially de-risk Chile’s dependence on volatile, but still profitable, merchant revenues.
Will new solar assets in Chile have storage components?
New utility-scale renewable and PMGE assets in Chile (most of which are distributed solar plants smaller than 9 MW) will likely all have storage components moving forward.
Why are project finance transactions increasing in Chile?
Fitch Ratings-Sao Paulo/New York-01 April 2025: Project finance transactions in Chile are expected to increase due to the recent commissioning of large battery energy storage systems (BESS), Fitch Ratings says. This should balance electricity supply and demand while reducing price volatility for renewable energy generators.
How can battery storage help reduce the financial impact of curtailment?
Battery storage systems can capitalize on this arbitrage opportunity and help reduce the financial impact of curtailment in hybrid solar power plants until large transmission line projects become operational, stabilizing cashflows. Chile has an operational installed capacity of approximately 1GW in batteries, and another 3GW is under construction.
