backup power battery cost breakdown in Chile 2025

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 energy storage will Chile have in ?

During the Energy Storage Summit Latin America (ESS LatAm) in October , Ana Lía Rojas, executive director at the Chilean renewable energy and energy storage association (ACERA), explained how the current levels of curtailment in Chile, which could end up at approximately 5TWh in , could power up to 3.4GW of 4-hour duration energy storage.

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.

Why is energy storage important in Chile?

Image: Grenergy Grid constraints have prevented Chile from maximising the potential of its world-class solar resources. Energy storage has, therefore, become a necessity to ensure the financial viability of PV projects, writes Jonathan Tourino Jacobo.

Should energy storage be a luxury asset in Chile?

Having energy storage in Chile is no longer a luxury asset but has become an “absolute necessity”, explains Alejandro McDonough, business development manager of Americas area sales at Wärtsilä Energy Storage and Optimisation (Wärtsilä ES&O).

Why are project finance transactions increasing in Chile?

Fitch Ratings-Sao Paulo/New York-01 April : 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.

We expect price differentials in Chile to fall as BESS-installed capacity grows and new transmission comes online adding more uncertainty to long term arbitrage revenues.

All Chilean energy storage players, ranging from IPPs to PCS providers, are now closely awaiting the publication of the capacity market decree (DS N 62) expected in Q2 of . This decree is expected to provide capacity payments based on the duration of storage projects as seen in the table below

In July , AES announced plans to construct a 763 MW solar plant with a 1,063 MW battery offering five-hour storage, as reported in pv magazine LatAm. Construction is expected to begin in April in the Antofagasta region in the north of the country, ahead of an expected commissioning date in

Grenergy’s Oasis de Atacama project, currently being built in phases, will co-locate 2GW of solar PV generation with as much as 11GWh of battery storage when completed. Image: Grenergy Grid constraints have prevented Chile from maximising the potential of its world-class solar resources. Energy

Aurora’s analysis highlights co-locating 5-hour batteries with solar installations can potentially double revenues through load shifting. It finds that 5-hour batteries cycling once per day offer the most cost-effective solution by capturing over 70% of zero-price hours. Crucially, under current

According to modelling by the International Energy Agency, Chile is on track to eliminate coal-fired power by and get to over 90% renewables on an annual basis by then. The latest: In January , coal made up less than 11% of Chile’s electrical output, a new monthly low, according to data
