▪ Abstract This article discusses briefly the status of energy storage technologies and explores opportunities for their application in the rapidly changing US energy marketplace. Traditionally, electric utility energy storage has been used to store low-priced purchased or generated electric energy for later sale or use when energy cost would otherwise be much higher. But deregulation and restructuring in the electric industry, coupled with an expanding portfolio of storage alternatives, may lead to many new opportunities for energy storage, especially within the energy distribution infrastructure, and for maintaining or providing power quality at large customer sites. Small, modular, robust energy storage technologies could be used to solve a range of energy supply and infrastructure-related needs. This article provides quantitative evidence of utility-related energy storage status, benefits, and opportunities.
