Italy’s electricity transmission system operator has awarded a tender to Younicos, Samsung SDI and Italian renewable energy producer Green Utility to provide 1MW/1MWh of battery storage aimed at stabilising Sardinia's electrical grid.
Younicos will install the battery, to be implemented as part of Terna’s 2012 Grid Defense Plan. The plan is one of two macro-projects the operator has launched involving investment in storage systems, the other being the 2011 Grid Development Plan.
The 2012 Defense Plan has two phases, with the Sardinia battery installed in the first phase, dubbed 'storage lab'. During this phase 16MW of large-scale energy storage will be deployed across several projects and their performance assessed via a series of pilot schemes. Following a successful storage lab trial phase, the second phase of the plan will see 24MW of storage deployed in Sardinia and Sicilly.
The 1MW/1MWh Sardinia battery system will be lithium-ion based, with another 1MW/1MWh that can be added as an option. Control software has been developed by Younicos, with the company’s chief technical officer Clemens Triebel saying Terna’s “ambitious” approach to storage made the operator a “role model for Europe”.
