How an Electrical Consultant Helps Reduce Energy Costs

Older lighting systems can consume more electricity than modern alternatives. However, simply changing lamps is not always enough. Businesses should also consider how lighting is controlled and when lights are required.

An electrical consultant can assess lighting layouts and operating patterns. Recommendations may include LED lighting, occupancy sensors, daylight controls, timers or improved switching arrangements.

For example, lights in meeting rooms may not need to remain on when the rooms are empty. Sensors can help reduce unnecessary use.

In warehouses and other large spaces, lighting controls can also help match illumination with occupancy and working patterns.

The right solution depends on the building and its use. A professional assessment helps avoid spending money on changes that provide little benefit.

Using Variable Speed Drives

Motors can account for a significant share of electricity use in industrial and commercial environments.

Pumps, fans, compressors and other motor-driven equipment may not always need to operate at full speed. Running a motor at a higher speed than necessary can result in wasted energy.

Variable speed drives (VSDs) allow motor speed to be adjusted according to demand.

An electrical consultant can assess whether VSDs are suitable for specific equipment. The consultant can consider the motor, operating conditions, control requirements and expected energy savings.

For businesses with many motors, even small improvements in individual systems can contribute to a meaningful reduction in overall electricity consumption.

Managing Electrical Loads

Energy costs are also influenced by when electricity is used.

Businesses with high power demand may benefit from better load management. This involves understanding when major equipment operates and whether some loads can be shifted or controlled.

An electrical consultant can review the building's demand profile and identify opportunities to improve the way electrical loads are managed.

For example, some non-critical equipment may be scheduled to operate at different times. Automated controls can also reduce unnecessary operation.

Load management becomes even more important when businesses add electric vehicle charging, solar PV systems, battery storage or new production equipment.

Reducing Standby Energy Use

Equipment that appears inactive may still consume electricity.

Computers, displays, printers, control systems and other devices can continue using power when left in standby mode. Across a large office or commercial building, this can add up.

A review of operating schedules can help identify equipment that remains powered when it is not required.

An electrical consultant can recommend suitable controls and operating strategies. These may include automatic shutdown systems, timers or centralised controls.

The goal is not to switch off equipment that needs to remain operational. Instead, the focus is on finding safe ways to reduce unnecessary consumption.
