2012 Performance Evaluation Review  
Energy storage -in the form of UPS units -in a datacenter has been primarily used to fail-over to diesel generators upon power outages.  ...  There has been recent interest in using these Energy Storage Devices (ESDs) for demand-response (DR) to either shift peak demand away from high tariff periods, or to shave demand allowing aggressive under-provisioning  ...  This typically takes a few seconds (at most a couple of minutes), and most datacenters provision UPS devices with lead-acid batteries of possibly 2X-3X this capacity.  ...
