Under the first phase of an agreement signed with Walmart on April 11, Advanced Microgrid Solutions of San Francisco will design, install, and operate 40 MWh of advanced energy storage at 27 of the discount retailer’s 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 regulated utility Southern California Edison .
Walmart has set an ambitious goal to power 50 percent of its operations with renewable energy sources by 2025 – and already has installed onsite generation, including solar PV, at 350 of its stores.
AMS’ Hybrid Electric Buildings platform “ automatically and efficiently optimize[s] a building’s overall energy usage, controlling energy consumption and lowering costs, while generating revenues from utilities for grid service,” the company said.. Southern California Edison, one of the largest grid operators in the U.S., will be able to tap into these advanced energy storage systems to reduce demand on the grid.
“Cost efficiency is the hallmark of the Walmart brand,” said the retailer’s VP for Energy Mark Vanderhelm. “Adding energy storage capabilities to our clean energy resources reduces the capacity needed from the grid and is part of our commitment to increase reliance on renewable energy.”
In a March 30 report, Bloomberg said that many of America’s biggest corporations, including Apple. and Wal-Mart Stores, “are sticking by their pledges to fight climate change even as President Donald Trump guts his predecessor’s environmental policies.”
Companies say their promises, coordinated by the Obama administration, reflect their push to cut energy costs, head off activist pressure and address a risk to their bottom line in the decades to come.
“This work is embedded in our business,” Wal-Mart spokesperson Kevin Gardner told Bloomberg in an email. It’s “good for the business, our shareholders and customers; if ultimately we are able to positively impact the environment in the process, that’s a win too.”
