During 2010, Advanced Energy engineers attended the Electricity Storage Association’s (ESA) annual meeting in Charlotte, N.C., conducted telephone interviews as well as internet research to learn about current and near-term community and residential energy storage technology. This report provides a summary of Advanced Energy’s findings. Several utilities including American Electric Power (AEP), Detroit Edison (DTE) and Sacramento Municipal Utility District (SMUD) have community energy storage demonstration projects underway. A brief description of each project is included in this report. In response to utility demand for distributed electricity storage systems, several manufacturers have developed CES units. As such, AEP and Electric Power Research Institute (EPRI), with input by utilities and other companies, have developed a specification for Community Energy Storage (CES) systems. A brief description of each of their projects is also included here.
