Which solar container lithium battery for energy storage in Chile is cheaper

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.

Will Engie Chile build a solar-plus-storage project?

The site, the first solar-plus-storage project built from scratch by Engie Chile, will feature 208 lithium-ion battery containers. Engie Chile wants 3.5 GW of installed energy capacity by 2027, with more than 60% of it renewable energy generation and battery capacity.

Can co-located batteries help solar plants capture better power prices?

Co-located batteries, like Engie S.A.’s BESS Coya, will help solar plants capture better power prices by charging the batteries during solar hours when power prices are very low and dispatching energy during peak hours when prices are close to USD 100/MWh.

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.
