The presentation was made at IEEE PES 2011 General Meeting Super Sessions in July, 2011. The presentation describes the role of testing in advancing Community Energy Storage (CES) and its challenges. The challenges presented by CES are not simply in the fact that we have a new technology, but rather in the manner for which CES is going to be utilized. Despite a great deal of activity in storage, the “precedent” has not yet been set for Community Energy Storage Systems. Differences with Community Energy Storage are that to date: Utility-scale devices have been utilized for single applications such as regulation or renewable ramping applications - utilization factors make it difficult to attempt to perform additional applications.
