Typical Food Retail Electricity use in Newfoundland & Labrador
Refrigeration is the highest user of electricitiy for supermarkets and grocery stores and can account for over half of total energy usage. Together space heating and lighting make up about 25% and are the next two biggest uses of electricity. Here are some upgrades you can make to reduce your electricity costs in these areas. Don’t forget you can get back up to $50,000 when you make eligible energy efficient upgrades to your business.
- Replace evaporator fan motors with ECM motors. This is especially effective for walk in coolers and larger fans. ECM motors can reduce energy use by over 50%.
- Install variable speed compressors. A compressor driven by a variable speed drive, better matches the refrigeration load and only works as hard as it needs to, thereby reducing energy requirements.
- Upgrade refrigeration to floating head pressure controls to reduce energy needs. The control system takes advantage of lower outside temperatures to reduce the refrigeration energy.
- Refrigerated Case Doors: Replace open coolers and freezers with doored units. Closed units will reduce energy use by 60% or more. The addition of doors means less cold air escapes into the store, resulting in less electricity use for refrigeration and space heating. Like most energy efficiency upgrades, the benefits go beyond energy savings. The doors also help reduce food spoilage and create a more comfortable shopping environment for customers.
- Heat Recovery – Use heat recovery from the refrigeration system for space and water heating. Refrigeration systems generate large quantities of heat that can be harnessed to provide water and space heating.
- When replacing fluorescent lighting, install high efficiency T8, T5 or LED. New energy efficient lighting such as LED can save you over 35% on your lighting energy costs. LED case lights can also make the merchandise look better.
- Replace incandescent Exit signs with LED. Get a $20 takeCHARGE rebate at select locations and save $300 over the life of the sign from reduced energy use and materials and labour for bulb changes.
- Exterior lighting. Upgrade exterior and parking lot lighting to LED, such as LED wall packs. Get $25 back for each LED wall pack you install and save up to 70% of electrical energy costs.
- Use day-lighting whenever possible.
- Occupancy sensors – Save up to 40% on lighting energy costs when you install occupancy sensors. Calculate your rebate.
Heating, Ventilation, Air Conditioning & Cooling
- Programmable thermostats – Save up to 10% in heating costs when you install programmable thermostats and get a takeCHARGE rebate. Calculate your rebate.
- Install a Mini-split heat pump – These units are great for small retailers and are economical to install. A mini-split heat pump can save you over 40% on your heating costs. They also offer the option of air conditioning for those warm summer months.
- Cold climate or low temperature air source heat pump (ASHP) systems are more efficient than conventional electric baseboards and are a great choice for larger buildings. These systems can achieve savings up to 50% over conventional electric baseboards.
- Larger retailers can use Building Automation Systems (BAS) to efficiently manage energy usage for the building. These systems can save up to 30% in energy costs.
- Address any building envelope issues:
- Roof Insulation
- Wall Insulation
- Gaps around doors, windows and entry point into the facility
