United Natural Foods Utilizes World Energy for Online Energy Procurement

PROVIDENCE, RI and WORCESTER, MA, April 28 /CNW/ - World Energy Solutions, Inc. (NASDAQ: XWES; TSX: XWE), a leading energy management services firm, today announced it has helped United Natural Foods, Inc. (NASDAQ: UNFI) procure over 25 million kWh of electricity and renewable energy for its distribution centers in Connecticut, Massachusetts, New Hampshire and Pennsylvania. Complementing its commitment to environmental sustainability initiatives and promoting Green energy, UNFI worked with World Energy to cost effectively purchase energy through successful auction events over the World Energy Exchange(R).

The online auctions tested various terms and energy mixes, attracting top suppliers in each respective state and spurring competitive bidding that yielded cost savings to UNFI for both traditional and renewable energy. Additionally, through the process, UNFI was able to secure 25 percent green power for its Massachusetts and Connecticut facilities, which will reduce carbon dioxide emissions by approximately 2,500 metric tons, or the equivalent of nearly 5,800 barrels of oil.
