What is Round Trip Efficiency?
Round trip efficiency (RTE) is the percentage of energy supplied to a storage system that is retrieved from it. Learn how RTE varies by technology, storage duration, age, charging rate, system design, and temperature.
Utility-Scale Battery Storage
Round-Trip Efficiency. Round-trip efficiency is the ratio of useful energy output to useful energy input. (Mongird et al., 2020) identified 86% as a representative round-trip efficiency, and the 2022 ATB adopts this value. In the same report, testing showed 83-87%, literature range of 77-98%, and a projected increase to 88% in 2030.
