Walmart expands solar footprint to Massachusetts

New York -- Walmart plans to install solar panels on about half of its stores in Massachusetts, making it the largest user of solar power in the state. Walmart is partnering with Greenskies Renewable Energy LLC, Middletown, Conn., on the project, which involves 27 stores. “On average, the systems we’ll be using in Massachusetts will provide from 10% to 15% of each store’s power requirements,’’ said David Ozment, Walmart’s director of energy programs. “We’re very optimistic that we’re going to save some dollars over time.”
