This study reviews international experience with pricing and compensation mechanisms for battery energy storage systems (BESS) in Australia, Germany, Ireland, Italy, Japan, Türkiye, Ukraine, and Great Britain. It examines lessons from efforts to scale up energy storage services across major power markets in Europe and the Asia-Pacific region and traces the evolution of regulatory policies, market access rules, use cases, payment models, support instruments, and common barriers to deployment.
It identifies lessons for each jurisdiction examined. Grid access is a significant obstacle, resulting in connection queues and delays in Great Britain, Germany, Australia, and Japan. Eliminating barriers and allowing revenue stacking have proved highly effective, but competitive markets alone are rarely sufficient to create a v iable business case. Longterm support instruments that provide predictable revenue can therefore be critical to securing financing for storage projects.
