The project is complete and had demonstrations at 29 different sites. The recipient collected baseline data and installed new, high efficiency electric equipment, such as toaster ovens, soup warmers, rice cookers, and espresso machines at 18 of these restaurants. Cumulative energy savings for all plug load equipment can be substantial. The appliance with the highest average daily energy use and potential for energy savings was the conveyor toaster. It uses more than 20 times the energy on average than the appliance with the lowest average daily energy use, the soup warmer. Frontier also tested induction and conduction cook tops. The COVID-19 pandemic has had a substantial impact on the food service industry and leaving a glut of used equipment on the market. The recipient has pivoted to meet the changing needs of industry by providing on-line webinars and developing virtual tools that focus on energy efficient equipment and low-carbon solutions.
This project assessed the reduction potential of electric commercial plug load foodservice equipment at 29 different commercial kitchens and demonstrates the potential for reduced energy consumption through the use of pre-commercial appliance designs and control technologies.
This project could lower energy costs by encouraging the adoption and implementation of advanced design and controls for commercial food service plug load appliances that use less energy than conventional systems. This could save up to $467 in annual energy cost per plug load appliance, with savings up to 65% for replacements. Total savings on the equipment could total over $1,500 annually if energy saving controls were optimized for each appliance and the site has a combination of a vertical toaster, food warmer, espresso machine, hot plate, rice cooker, and soup warmer. The COVID-19 pandemic has had a substantial impact on the commercial foodservice market.
