Probably, the chain of 1600 Hannaford's-Food Lion super-markets in the United States (2600-worldwide) is able to utility shop from all the hundreds of electric ultilities across the U.S. and get a lowest price-highest quality type of an electric deal for themselves. With all those refrigerated displays/store, it's got to add up to lots of power use and lots of electric power savings for Hannaford.
Sorry to hear about the Moultonborough grocery & gas closing up. If you are looking to shop a genuine local store with super quality and good prices....maybe take a peek at Heath's Super & Heath's Hardware in Center Harbor. If Heath's were to close up then only Hannaford would be remain.
Surprise....Heath's Hardware Store now has courtesy cups of hardware store coffee from Vermont Green Mt coffee roasters for all us local losers who are just look'n to kill some time in a nice warm store

! Way-to-go.....Heath Hdwe
