How long is the warranty period for Chilean energy storage batteries

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 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.

Is Chile ready for a battery storage project?

Battery storage projects cannot come soon enough for Chile. While Chile has been at the forefront of renewable energy generation growth in Latin America for close to a decade, that growth has most recently undergone serious growing pains.

Will capacity payments be applicable to energy storage systems in Chile?

Pursuant to Law 21,505, the Chilean Ministry of Energy has proposed to amend the regulations on capacity payments to allow for those payments to be applicable to energy storage systems.

What happens if a battery loses a 10 year warranty?

At the end of the 10-year period, the battery is guaranteed not to have lost more than 20% of its storage capacity. It will act like a 4 kWh battery in the worst case scenario. If it loses more than 20% of its capacity, then you are entitled to a battery replacement, as the warranty terms will have been broken.

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.
