Roundtrip efficiency is a key performance measure for an energy storage system, describing how much energy is lost over a full cycle of charging and then discharging. It is defined as the energy delivered during discharge divided by the energy supplied during charging, expressed as a percentage, with a higher figure meaning lower losses and lower operating costs; round trip efficiency has a strong effect on the economics of energy storage, particularly for grid stability, integrating renewable energy and managing peak demand.
