Feasibility of Distributed Electricity Storage

Four different business cases have been analysed for generating benefits from small-scale electricity storage systems. Benefits differ substantially from case to case. The imbalance market appears to be financially most attractive. This case has been worked out in more detail, in which a distinction has been made between active and passive contribution. It can be concluded that grid-connected electricity storage in small, distributed storage systems appears to be financially attractive, provided that battery costs fall significantly below €500 per kWh.
