The levelized cost of storage (LCOS) is a metric used to evaluate the economic feasibility of energy storage systems by calculating the per-unit cost of storing electricity over the lifetime of the system. It takes into account various factors including capital costs, operational expenses, and the total energy delivered over time. This concept is crucial for understanding how different energy storage technologies compare in terms of cost-effectiveness, influencing decisions about sizing, placement, and optimizing the operations of these systems.
