Optimising energy efficiency: the potential benefits of voltage optimisation in business

FESPA’s Associations and Technical Lead, Graeme Richardson-Locke, discusses the advantages of voltage optimisation for businesses looking to reduce energy consumption and operational costs, as well as offering a more sustainable approach to business operations.

In the quest for sustainable and cost-effective business practices, energy efficiency is a paramount consideration for enterprises worldwide. Voltage optimisation technology presents a promising solution to reduce energy consumption, cut operational costs, and promote a greener approach to business operations. This article explores the potential benefits of voltage optimisation in a business-to-business context, delving into its functionality, applicability and potential percentage energy savings.


  1. The concept of voltage optimisation: Voltage optimisation is a proven technique designed to regulate voltage levels within electrical systems to achieve energy efficiency without compromising on functionality. In many electrical distribution networks, the voltage is intentionally set higher than necessary to compensate for voltage drops during transmission. However, this practice leads to energy wastage and increased wear and tear on electrical equipment.
  2. How voltage optimisation works: Voltage optimisation technologies work by analysing the incoming voltage and adjusting it to the optimum level required by connected equipment. By reducing the voltage to an appropriate level, businesses can significantly lower their energy consumption, leading to direct cost savings on electricity bills.

  3. Energy savings in a business setting: Across various industrial sectors, voltage optimisation has demonstrated substantial energy savings potential. Studies indicate that businesses can achieve energy savings ranging from 5% to 20% or even higher, depending on the specific circumstances. By implementing voltage optimisation solutions, companies can improve their energy efficiency metrics and enhance their environmental sustainability efforts.

  4. The relevance of voltage optimisation in the European Union (EU): Voltage optimisation technology is applicable not only in the UK but also across the EU. The majority of EU member states adhere to a nominal voltage of 230V for single-phase electrical systems and 400V for three-phase electrical systems. The effectiveness of voltage optimisation varies based on the existing electrical infrastructure and voltage regulations in each country.

  5. Benefits for three-phase equipment: Businesses that rely on three-phase equipment, such as motors, compressors and heavy machinery, can benefit significantly from voltage optimisation. Three-phase equipment operates more efficiently and delivers higher power output when supplied with stable and balanced voltages. Voltage optimisation can ensure balanced voltage levels, reduce equipment heating, improve power factors and extend the lifespan of the machinery.

  6. Industrial case studies: Numerous case studies illustrate the tangible advantages of voltage optimisation in diverse industrial settings. In a study conducted by the National Physical Laboratory in the UK, energy savings of around 12% for lighting and office equipment and up to 15% for refrigeration and air conditioning systems were achieved. A case study by the US Department of Energy reported energy savings of approximately 5% to 10% in an industrial facility
  7. Implementation and savings projection: To realise the full potential of voltage optimisation, a comprehensive energy audit is essential. Engaging with qualified professionals who specialise in voltage optimisation for industrial applications can help businesses assess the precise savings that can be achieved in their specific context. By understanding voltage levels, equipment performance and electricity consumption patterns, businesses can project the percentage energy savings that voltage optimisation will bring.

Voltage optimisation technology offers a promising pathway for businesses seeking to enhance energy efficiency, reduce operational costs and demonstrate environmental responsibility. With potential energy savings ranging from 5% to 20%, or even higher, this technology can significantly impact the bottom line while promoting a greener business approach. As the world increasingly embraces sustainable practices, voltage optimisation stands as an accessible and effective solution for businesses across the EU and beyond. By leveraging this technology, businesses can bolster their competitiveness, align with green initiatives, and pave the way for a more sustainable future.
