Advanced Microgrid Solutions (AMS) says it will work with Wal-Mart Stores Inc. to deploy 40 megawatt-hours of advanced energy storage systems at 27 stores in Southern California.

These energy storage systems will allow the retailer to reduce costs by reducing each store’s peak electricity demand while providing dispatchable grid support to Southern California Edison.

AMS says that its platform uses energy consumption data, retail and wholesale energy prices, carbon intensity, and efficiency metrics to create a diagnostic energy profile for each building. The AMS platform is intended to optimize energy resources in real time at the building level, the fleet level, and across portfolios.

Under the agreement, AMS will design, install, and operate the energy storage systems in an effort to improve efficiency, guarantee energy savings, and provide grid support. No upfront cost to Walmart is expected.

Walmart aims to power 50% of its operations with renewable energy sources by 2025, and has already installed onsite generation, including solar photovoltaics, at 350 of its stores.

Southern California Edison will be able to tap into the energy storage systems to reduce demand on the grid.

AMS designs, finances, installs and manages advanced energy management solutions for commercial, industrial and government building owners. AMS’s energy storage portfolio management software provides continuously optimized resource management, cost reduction, and revenue generation for large-scale energy users and utilities.
