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.

Is Chile ready for a standalone energy storage project?

This project alone nears the capacity (13GWh) the Chilean Ministry of Energy sought in a public land bidding auction for standalone energy storage projects in May of 2024. Chile has been one of the countries at the forefront of the renewable energy transition in Latin America, first with solar PV and now with BESS.

How much energy storage will Chile have in 2024?

During the Energy Storage Summit Latin America (ESS LatAm) in October 2024, 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 2024, could power up to 3.4GW of 4-hour duration energy storage.

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).

Does Chile need a nighttime electricity supply?

“Mining represents roughly 60% of the total energy consumption [in Chile]. Out of roughly 12GW, nearly 7-8GW comes from mining, all of which need to be supplied 24/7. There’s a lot of space [to supply with batteries],” explains McDonough. Rojas outlined the urgent need to decarbonise the nighttime electricity supply in Chile.
