7-Eleven is bringing fast charging to NYC motorists in the days ahead, having announced plans to deploy Green Charge Networks energy storage solutions.
7-Eleven and GCN worked with the U.S. Department of Energy (DOE) and several large utility companies to leverage local solar generation and energy storage, which enables the use of high-powered electric equipment, including EV fast chargers. This avoids extreme consumption peaks that lead to expensive electricity-demand charges for commercial rate payers.
Green Charge Networks’ energy storage system, GreenStation, manages the power consumption at the 5820 Francis Lewis Boulevard 7-Eleven location in Flushing, N.Y. It monitors the store’s load on a second-by-second basis and counteracts peaks and valleys by discharging and charging from an internal ion battery bank.
"Even when the New York City electric grid experienced an all-time peak on July 19 during the recent heat wave, the GreenStation allowed for EV fast charging while reducing peak demand by 56 percent," says Vic Shao, Green Charge Networks’ CEO.
"Convenience retailing in today’s world increasingly requires the use of high-powered electrical devices, including foodservice equipment and EV fast chargers," adds Tom Brennan, 7-Eleven’s vice president of infrastructure services. "Meeting our customers changing needs while keeping demand charges and thus our electricity costs in check is a very attractive value proposition for us."
The GreenStation empowers industrial and commercial ratepayers to manage power consumption and rising demand charges. The energy-storage product is easy to install, maintenance free and economical. The root technology is a stochastic controller with sophisticated software that flattens the power load curve during peak consumption periods, with positive financial implications for the customer and electricity utility.
