Demand response programs across the country have many large facilities considering the deployment of energy storage technologies. Technologies developed for facility- and campus-scale energy storage show promise for managing short-term demand peaks as well as longer-period demand response events.
The presenter has investigated facility/campus-scale energy storage for efficiency program administrators in the US and recently completed a storage technology research report for an international consortium of utilities. This work has identified promising avenues for distributed storage. Currently, facility-scale storage has three primary uses: 1. power quality – the monitoring and regulation of voltage fluctuations, frequency disruptions, and harmonic distortions, 2. bridging power – short-term power supply for critical demands, often used to cover time periods in which emergency generators are powering up, 3. energy management – energy storage on a scale to support a facility/campus for extended periods of time. These systems can be responsive to utility demand programs and time-of-use rates to cut peak demand costs.
This presentation will include the technical properties of current storage systems, including flywheel, compressed air, and various battery technologies. The technical and market barriers associated with distributed storage, along with proposed paths for resolving said barriers, will also be discussed.
