Walmart is also at the forefront of commercializing storage technology and was a pilot customer for SolarCity’s energy storage system for businesses. Since early 2013, Walmart has tested 13 battery storage projects with solar installations across California to provide additional savings to Walmart by using stored electricity to lower peak demand charges. The next ten solar energy storage projects will each use a larger 200 kW (400 kWh) battery, expanding battery storage capabilities as well as further reducing energy expense.
