Typical Manufacturing Electricity use in Newfoundland & Labrador


    Motors are the biggest users of electricity in Newfoundland and Labrador’s manufacturing sector, followed closely by HVAC, lighting and air compressors. Read on to see how you can reduce your electricity costs in these areas and don’t forget you can get back up to $50,000 when you make eligible energy efficient upgrades to your business.


    • Buying new motors? When it’s time for replacement opt for premium-efficiency motors which can be up to 8% more efficient when compared to standard motors. Also choose the correct sized motor for the job. Motors operate most efficiently between 75% and 100% of their full load rating.
    • Vary the run speed – Use variable speed drives when the motor doesn’t need to operate at full power at all times. Variable speed drive (VSD) motors can use over 35% less energy compared to motors running at a constant speed. VSDs also allow for a ‘smooth startup’, ultimately extending the life of the motor.
    • Switch to efficient belts – Consider switching the V-belts to synchronous belts on motors in your facility. Synchronous belts offer increased reliability and are about 3% more efficient than V-belts. Due to their design, synchronous belts are less prone to slippage, improving their efficiency and do not require re-tensioning after installation.
    • Voltage – Make sure the voltage applied to the motor is as close to the design limits as possible. (The limit can be found on the motor’s nameplate). Increasing the voltage at the motor outside of its design limits can lead to a decrease in the power factor. Lower power factors may be monetarily penalized by your power company.
    • Set continuous use motors to shut down or “sleep” after a certain period of inactivity or during hours when the building is unoccupied.
    • Perform regular cleaning and maintenance – Tighten belts and pulleys to prevent slippage, lubricate motors and drives regularly to reduce friction and replace worn bearings.

    HVAC Fans and Pumps

    • For larger offices, the use of a Building Automation System (BAS) will efficiently manage energy usage for the building. These systems can save up to 30% in energy costs.
    • Where applicable, install adjustable speed drives on fans and pumps. Adjustable speed drives can decrease energy use by over 35%.


    • LED Wall Packs – Get $25 back for each LED wall pack you install and save up to 70% of electrical energy costs.
    • Occupancy sensors – Save up to 40% on lighting energy costs when you install occupancy sensors. Calculate your rebate.
    • 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.
    • Replace incandescent Exit signs with LED. Get a $20 takeCHARGE rebate at select locations. You save over $200 over the life of the sign in reduced energy costs and reduced material and labour for bulb changes.
    • Minimize exterior lighting. At night only use what you need for safety and security purposes.
    • Use day-lighting whenever possible.
    • Encourage employees to turn off the lights at the end of the day.

    Air Compressors

    • Monitor, check and inspect all components for wear, proper temperatures and settings, leaks, proper lubrication and clogged filters.
    • Inspect the system regularly and fix any leaks. Repairing leaks can save up to 50% of your compressed air annual energy costs and help improve the system operations.
    • Use compressed air only when it is necessary. Shut down your central compressor during non-working hours. If small amounts of compressed air are required, separate those uses from the main system and supply them from a smaller compressor.
    • Maintain air pressure at the lowest pressure acceptable.
