US retail giant signs energy storage deal

San Francisco-based startup Advanced Microgrid Solutions (AMS) has been selected by Walmart to install its advanced energy storage systems at a number of the US retailer’s Southern California stores.

Under the agreement, AMS will design, install and operate these systems, and in doing so will
apparently improve efficiency, guarantee energy savings, and provide fast, flexible grid support to local utilities, all at no upfront cost to Walmart.

In the first phase of the project, AMS will install 40 megawatt hours (“MWh”) of advanced energy storage systems at 27 stores in Southern California. These energy storage systems will allow the retail giant to reduce costs by permanently reducing each store’s peak electricity demand while providing dispatchable grid support to Southern California Edison (“SCE”).
