SUGAR LAND--April 30, 2018--Written by John Egan for Industrial Info Resources (Sugar Land, Texas)--Electricity storage, principally in the form of lithium-ion batteries, is widely regarded as the next big thing that will transform all sectors of the electricity business--generators, transmitters, distributors, energy-services companies and renewable-power developers. Industrial Info is tracking roughly three dozen battery-storage projects in the U.S. valued at slightly more than $1 billion. Many analysts expect that to grow significantly in the next few years. Virtually each day brings another announcement by an electric utility of a new battery-storage deployment. Regulatory commissions are a principal force driving increased deployments, which have helped dramatically reduce the cost of storage.
