This project will utilize 20 MW of A123 lithium-ion batteries to supply a flexible and scalable emissions-free reserve capacity installation for AES Gener. The advanced energy storage installation provides critical contingency services to maintain the stability of the electric grid in Northern Chile, an important mining area. It continuously monitors the condition of the power system and if a significant frequency deviation occurs—for example, the loss of a generator or transmission line—the energy storage system is capable of providing up to 20 MW of power nearly instantaneously. This output is designed to be maintained for 15 minutes at full power, allowing the system operator to resolve the event or bring other standby units online.
