ABSTRACT
This chapter considers the technical properties of storage systems, including flywheel, compressed air, and various battery technologies. Technologies developed for facility- and campus-scale energy storage show promise for managing short-term electrical demand peaks as well as longer-period demand response events. The chapter focuses on the practical considerations of customer energy storage applications, the energy storage technologies currently available, and the primary barriers to widespread behind-the-meter energy storage implementation. Energy storage has become a proven solution for demand response events, peak demand reduction, power quality regulation, and emergency response power supplies. While there are several technologies that support facility-scale energy storage, batteries and flywheels are the most mature and readily available technologies. Advancements in flywheel technologies during the last 15 years have enabled them to compete with batteries in the power quality and dependability markets. Improved marketing and better education of building owners can help overcome these market barriers.
