Voltage optimisation systems

What is Voltage Optimisation?

Voltage Optimisation is the reduction of voltage to a site to reduce energy use.

Reducing or stabilizing the voltage has further benefits; reducing maintenance and mechanical loads.


Why is it important for your business?

In accordance with Australian Standards (AS) 60038, electrical supply is delivered at a nominal voltage of 230/400 Volts, with tolerances of -6% to +10% of the nominal voltage. All equipment used within a circuit in Australia is required to operate within these tolerances.

What this means for your business is that all equipment within the circuit should operate between a bandwidth of 216.5V – 253V at the same levels of performance.

To ensure electricity supply to the furthest point on the grid, sometimes voltage is supplied much higher than the nominal voltage. Also, voltage will fluctuate based on the supply and demand within the grid, adding stress on equipment and energy loss through heat and vibration.

What does a Voltage Optimisation system do?

Beovista’s Beolec Mark 4 Voltage Optimisation system is an industrial voltage regulator designed to automatically maintain a constant set-point voltage.

To achieve this it uses a robust and maintenance-free design to accurately maintain the lowest reliable operating voltage thereby maximising the power savings of any site. It also measures, consolidates, and reports energy usage and savings information in real time and this data is directly accessible through the customer web portal.

Is it right for your business?

1. Preliminary analysis

We’ll look at your previous electricity bills and metering data

2. Site inspections

We’ll arrange to come to your sites and review your equipment and processes

3. Installation

We’ll commission each site and we’ll help support any planned shutdowns if required

4. On-going review

Each system is calibrated to each site and we’ll regularly review savings actualized.

Frequently asked questions

Electrical equipment is not perfectly efficient meaning less than 100% of the electrical power is converted to mechanical power. Using the lift as an example, the mechanical output is moving the lift. This does not change regardless if the Beolec is installed or not. The lift will still move say 5 floors. When the lift moves however, the motor is not perfectly efficient so when the Beolec supplies the lift motor then other motor power losses reduce, particularly when it is lightly loaded. So in summary, the lift moved the same distance but it took a little less power to get there.

The Beolec reduces the power required by the downstream electrical loads. Reduced energy demand means lower energy bills.

Voltage imbalance wastes energy in motors and transformers and can cause the costs of repairs and maintenance on a plants equipment to be higher than expected. Aligning phases and providing a smooth continuous flow of predictable voltage can result in improved maintenance of motors, lighting and electronics. A customer across four sites saw a reduction in maintenance costs of $17,000 across six months. This represented a 40% reduction in maintenance costs.

Reducing voltage reduces your kWh consumption of electricity. This is the major metric that your electricity bill tariff rates are charged. By reducing your kWh consumption you are able to reduce your energy bill by up to 20% with an average reduction sitting between 6-12% across the variable component of your electricity bills. On an average $250,000 annual electricity bill this represents a $13,000 saving per year or $150,000 across the length of our licensing agreement.

Simply, voltage reduction reduces kWh consumption of electricity the major volume metric your utility providers tariff structure is charged against. Reducing kWh will equate to a reduction in your electricity bill.
