Benchmarking Battery Performance: Insights from 100+ Operating Energy Storage Sites

Synopsis

Battery energy storage is essential to grid reliability and affordability considerations, yet performance across assets still varies widely. Drawing from ACCURE’s 2025 Energy Storage System Health & Performance Report, this session reveals the state of the industry based on operating data from more than 100 large-scale systems worldwide. Ted James will share independent, data-driven insights into where assets excel and where they fall short — from commissioning delays to state-of-charge errors and efficiency losses. Attendees will gain an evidence-based view into how small performance deviations can result in major financial losses and how the best operators achieve high returns.
