Several different trends are converging to make battery storage more attractive. Battery pack costs have dropped from about $1,000 per kilowatt-hour in 2010 to $230 per kilowatt-hour in 2016, according to a report released in June by McKinsey & Co. At the same time, energy rates continue to soar, and many states—including California, New York, Massachusetts, and Hawaii—are turning to incentives to help push companies to find ways to manage their consumption.
