Supermarkets are among the most energy-intensive commercial buildings. Refrigeration alone accounts for about half of a supermarket’s total energy consumption. And ever more supermarkets are adding in-store food service for customers. Not only do grocery stores stand to lose valuable inventory and prepared food during a power outage, but they could also lose customers wanting to buy food and other supplies. Keep your grocery store open for business during a power outage - and gain a competitive advantage - with a Generac standby power system.
