The Siemens division Infrastructure & Cities has put an energy storage solution into operation in Italy. The installation was completed at the end of February and is a pilot plant with an output of 1 MVA and a capacity of 500 kWh. The energy storage solution comes from the Siestorage series and has been installed in the medium voltage distribution network of Enel, the biggest power utility of Italy, headquartered in Rome. Enel will use it to study new Smart Grid solutions for voltage regulation, the integration of renewable energy sources into the medium voltage network, the integration of an electric vehicle charging station into the medium voltage network as well as to study black start capabilities.

•Siemens has developed, in conjunction with one of the world’s largest manufacturers of lithium ion batteries, a modular energy storage system that consists of a compact battery and converter cabinet as its smallest unit, but is expandable up to 2 MWh and 8 MVA.
