Powerstar - Voltage Optimisation (VO) System
Voltage optimisation (VO) is a transformer-based technology which optimises the incoming supply from the national grid to match the voltage required by equipment at your organisation. Optimising the voltage will reduce your commercial energy use and costs as well as lowering your carbon footprint and CO2 emissions at the same time. It’s sometimes referred to as Voltage Management or Voltage Regulation.
Spikes, sags, or fluctuations in your voltage supply or a consistent overvoltage can cause damage to equipment, disrupt operations, and waste energy. Sudden changes in voltage can trip sensitive electrical equipment. Consistently supplying equipment with a higher voltage than required can cause damage or premature burnout.
Optimising, conditioning, and reducing your incoming voltage supply protects your electrical equipment while reducing electrical consumption, costs, and carbon emissions. The Importance of commercial voltage optimisation, regulation & management cannot be underestimated for any business looking to develop a net-zero strategy. We do not offer Voltage Optimisation for domestic premises.
The benefits of commercial voltage optimisation for your business include:
- Lower Your Carbon Emissions – Lowering your carbon footprint and increasing your business’s green credentials and helping you towards your Net-Zero target
- Waste Less Energy – Using less energy means lower electricity bills saving your business money. A typical business could save thousands of pounds every year.
- Improved Power Quality – Better power quality means less wear and tear and maintenance costs for your electrical equipment potentially significantly prolonging it’s life.
- Smart Energy Management Systems – Monitor your energy savings to see just how much you are saving. – All Powerstar Voltage Optimisation systems are fitted with Remote Monitoring Capability
An added benefit of voltage optimsiation for your business can also be the reduced maintenance costs, which leads to increased operational lifespan for your electrical equipment. By stabalising and resolving any power flow harmonics issues which can be found in some buildings the lifespan on your electrical equipment can be considerably increased. An example of this can be found in our St Johns School and Sixth Form College case study.
Powerstar’s voltage optimisation solutions have online, remote monitoring capabilities, providing full visibility of asset performance, savings, and more. Unlike other providers, our solution uses a unique patented method for regulating the voltage.
Guaranteed Voltage Optimisation SavingsWhen we complete a voltage optimisation proposal for you we will give you a guaranteed savings amount. If your savings are below the guaranteed saving we will refund the difference. So with Powerstar, you are guaranteed to save!
How does this guarantee work?We base our proposals on your site having a 242V supply, this is the national average supply voltage. We use this and the supplied usage data to work out how much you will save. If after the first year you don’t hit the percentage saving and all other conditions are met we will refund the difference.
We can also conduct an installation feasibility study to give you an even more accurate saving amount.
The cheapest and greenest energy is the energy you don’t use.

Why voltage optimisation is necessary?
Voltage optimisation, or regulation is necessary because the voltage of electricity supplied by the National Grid typically fluctuates. In order to meet their binding requirement of supplying users with 230V, with a tolerance of +10% and –6%. This means that in practice, UK sites can be supplied with voltages ranging between 216V and 253V. The National Grid actually supplies a higher average voltage – typically around 245V – to ensure that the lowest value is still acceptable.
In the UK, electrical equipment is generally designed to work at 220V. This means that it is always operating at a higher voltage than necessary, which causes damage and reduces its working lifetime.
How does a voltage optimiser work?
We use our own patented technology to achieve the voltage reduction, which is far more efficient than other voltage optimisation or regulation solutions. Traditional solutions transform the entire voltage supplied to a site, and thus suffer large losses. The Powerstar solution transforms only the reduced voltage and therefore loses far less energy in doing so.
Voltage management also smooths out the peaks and troughs that can occur in voltage supply from National Grid, making your site more resilient by supplying equipment with a steady, reliable voltage and avoiding sudden surges or sags in the supplied power
The technology can either provide a set level reduction for high, but stable incoming voltage profiles, or can dynamically regulate a fluctuating voltage profile to maintain a desired, & optimum level.
