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.

How long does a battery last in Chile?

Moreover, the lack of an ancillary services market in Chile discourages shorter duration batteries (1-2 hours) as seen in the US and Europe. The general industry consensus is to maximize the availability of the battery and focus on 2-3 revenue streams instead of 4 to 5 (e.g., energy arbitrage, capacity payment, and frequency reserve).

Why should you invest in land at Cockenzie?

Land at Cockenzie may also present significant opportunities for renewable energy-related investment. The council will work together with developers, the landowner, the relevant agencies, local organisations and interested parties, including local residents to ensure that the best use is made of the existing land and infrastructure in this area.
