Big Y Foods

The Big Y Supermarket in Lee, Massachusetts is the first of four stores in the chain to receive an energy portfolio makeover. A 343 kW solar energy system – funded by a PPA through Smart Energy Capital, owned and operated by Hudson Energy Solar, and installed by RGS Energy in August 2012 – sits atop the western Massachusetts store and generates clean, inexpensive electricity for it. The store’s café features a flat panel monitor that displays the system’s real-time operation data for interested customers to learn how the system above their heads is working.

“For nearly four decades, Big Y has been committed to conserving energy and reducing waste,” noted Gary Kuchyt, manager of Big Y Foods’ energy and sustainability programs. “Preserving resources is important to us as a company – not only is it good business, it’s simply the right thing to do.”

Big Y is already under contract for solar energy installations at three more of their stores for a grand total of 2.7 megawatts, using the same Smart Energy Capital / Hudson Energy Solar / RGS Energy partnership.

RGS Energy installed over 1,100 pv modules on the store’s roof and on solar awnings along its face. The solar array, visible from the Massachusetts Turnpike, provides 15% of the building’s energy needs.
