Voltage optimisation

In today’s world, where energy consumption is a pressing concern, businesses and individuals alike are seeking ways to reduce their electricity bills, lower their carbon footprint and make their operations more sustainable. One effective technology that has gained significant attention is voltage optimisation. Powerdown220 is the UK’s leading expert in voltage optimisation solutions, offering high quality voltage optimisers, professional installation and exceptional project support.


Understanding voltage optimisation

Voltage optimisation is a smart and proactive approach to manage electricity consumption by controlling the incoming voltage supplied to electrical equipment. Average UK voltage is 242v, around ten per cent higher than equipment requires. This higher voltage not only leads to increased energy consumption, but also results in higher electricity bills and unnecessary wear and tear on electrical appliances.

Voltage optimisation lowers the incoming voltage to a level that is more suitable for the electrical equipment’s efficient operation. By optimising their voltage, businesses can achieve significant energy savings and reduce their carbon emissions, making a positive impact on the environment.

How voltage optimisation works

Voltage optimisation systems are installed between the incoming electrical supply and the electrical equipment, acting as a buffer. These systems monitor the voltage levels and adjust them to ensure a consistent and optimal voltage range. 

The optimisation process involves stepping down the voltage when it exceeds the desired range and slightly boosting when it falls below the required level. This way, electrical equipment receives a steady, regulated supply of voltage, maximising its efficiency and lifespan.

Benefits of voltage optimisation

  • Reduced electricity bills

    One of the primary advantages of voltage optimisation is its potential to deliver substantial cost savings on electricity bills. By utilising only the necessary voltage, energy consumption is lowered, resulting in reduced expenses over time. At Powerdown220, our typical customer saves between seven and twelve percent on their electricity bill through our voltage optimisers.

  • Extended equipment lifespan

    UK Wiring Regs (BS7671) states that powering equipment at a constant voltage of 240v and above can decrease its lifespan by up to 46 per cent. Voltage optimisation mitigates the wear and tear caused by excessive voltage, increasing the lifespan of electrical equipment. This leads to lower maintenance and replacement costs, contributing to long-term savings.

  • Lower carbon emissions

    By consuming less electricity, thanks to voltage optimisation, businesses and individuals play a part in reducing carbon emissions. This aligns with sustainability goals and environmental responsibilities.

  • Enhanced return on investment (ROI)

    Investing in voltage optimisation technology yields a quick and substantial return on investment. The savings on electricity bills quickly offset the initial investment, providing long-term financial benefits. 

  • Efficient voltage management

    Voltage optimisation ensures a consistent and stable voltage supply, improving the performance of electrical equipment, such as power supplies and variable speed drives.

Voltage optimisation is a smart solution that empowers businesses to save energy, reduce electricity bills, and contribute to reduce emissions targets. Our voltage optimisation machines come with intelligent monitoring software, that allows customers to see their savings in real-time through their own portal, download reports on their usage, and notice spikes and surges happening across their site.

Powerdown220, with its expertise in voltage optimisation technology, offers high quality optimisers, professional installation services and exceptional after-sale support. We can support your project from start to finish.


Where is voltage optimisation used?

Voltage optimisation is used by a wide range of entities, including:

  • Commercial and industrial businesses

    Many businesses across various industries, such as manufacturing, retail, hospitality, and data centres, implement voltage optimisation to reduce energy consumption and lower electricity bills.  Industrial facilities in particular, with a significant number of electrical equipment and high energy demands, can benefit greatly from this technology.

  • Public sector organisations

    Government agencies, schools, universities and hospitals often use voltage optimisation to minimise energy costs and enhance their sustainability efforts. These institutions have large energy footprints and can achieve substantial savings through voltage optimisation.

  • Hospitality sector

    Hotels, restaurants, and other hospitality establishments can benefit from voltage optimisation by reducing their energy costs, thus improving their bottom line and promoting their eco-friendly practices to customers.

  • Retail stores

    Retail chains and individual stores implement voltage optimisation to cut operational costs and reduce their carbon footprint. For retail businesses with multiple locations, voltage optimisation can lead to substantial cumulative savings.

  • Data centres

    Data centres, which consume massive amounts of electricity to operate and cool their servers, can achieve significant energy savings with voltage optimisation technology. This efficiency improvement aligns with the data centre industry’s growing focus on sustainability.

  • Renewable energy integration

    Voltage optimisation can also be used in conjunction with renewable energy sources like solar and wind power. It helps in stabilising and optimising voltage levels to ensure seamless integration and efficient use of renewable energy in the grid.

We supply voltage optimisers to businesses across the UK in every sector, from manufacturing to hospitality.
