Community Energy Storage (CES)

Introduction

Community Energy Storage (CES) consists of multiple small battery-based energy storage units connected to the utility transformers’ 240/120 V secondary and controlled from a common remote control. Initially the individual CES Units will be pad-mounted and typically be deployed in Underground Residential Distribution (URD) settings adjacent to a single phase pad mount transformer. A large number of these small storage units will be aggregated regionally and controlled as a fleet (see Figure 1).

The individual CES Units will have controls to manage their individual charge and discharge activity in response to regional needs at the circuit, station, or system level. The regional needs will be managed by a CES Control Hub or by integration into another control platform, herein referred to as an Integration Platform. If used, the CES Hub will be deployed as hardware and software typically installed at the station for the circuit(s) on which its fleet of CES Units are installed. A utility may elect to implement the same control functionality in an Integration Platform which has broader application, possibly including other distributed resources. The Integration Platform would not require the hardware on which the CES Hub will implement this regional control functionality.
