When businesses are searching for energy-saving technologies, there are a variety of options to consider. However, not all these technologies are equally well-known, and some don’t receive the same level of government backing. In this article, Josh Connolly, marketing manager at Powerdown220, argues that voltage optimisation has been wrongly overlooked as a significant energy-saving solution.
In today’s energy crisis, businesses are eager to save money on their electricity bills and operate more sustainably. You may assume that a widely available technology capable of achieving both goals would already be well known, but have you heard of voltage optimisation?
In the UK, the National Grid supplies electricity at an average of 242 volts, while most electrical equipment is designed to operate efficiently at around 220 volts. This means many businesses are paying for unnecessary excess voltage. Additionally, over-volting equipment not only costs more in terms of energy use, but it also shortens the lifespan of machinery and appliances.
Voltage optimisation addresses this problem by regulating the incoming voltage to the appropriate level for your equipment. The result? Businesses typically save around eight percent on their energy bills, while simultaneously reducing their carbon footprint.
The principle behind voltage optimisation is simple: by supplying electrical equipment with the exact voltage it needs, businesses can save on energy use while improving equipment efficiency. Despite this, voltage optimisation remains relatively underused, even though it can offer a quicker return on investment (ROI) than more commonly known technologies like solar panels. Typically, businesses that install voltage optimisation units see a return on investment within 18 months.
Given these benefits, why is voltage optimisation not more widely recognised or adopted?
In my experience, it’s rare to meet facilities managers who have heard of voltage optimisation. It’s a hidden technology, operating out of sight and mind. Unlike solar panels, which are often installed in visible locations like rooftops, voltage optimisers are typically located in basements or out-of-sight electrical rooms.
For example, many Toby Carvery and Harvester restaurants are fitted with voltage optimisers. Earlier this year, Powerdown220 completed the largest rollout of voltage optimisation in UK history, installing optimisers across 1,100 sites. But, since these units are tucked away, the technology remains largely invisible to the public.
The potential for voltage optimisation to reduce the UK’s energy consumption is vast. In 2023, the UK used 266 terawatt-hours (TWh) of electricity. If voltage optimisers were installed across the UK, delivering an average eight percent reduction in consumption, the country’s energy use could be cut by 21 terawatt-hours. This significant reduction in energy demand would make a notable contribution to the UK’s sustainability goals.
Voltage optimisation may not be the most talked-about energy-saving technology, but that doesn’t mean it’s any less valuable. As Ged Hebdige, Powerdown220’s electrical engineer, points out, “voltage optimisation isn’t ‘sexy’, but it’s effective.” While solar panels are visible and attract attention, voltage optimisers quietly go about their job of saving energy and reducing costs.
For businesses serious about cutting energy costs, improving sustainability, and extending the lifespan of their equipment, voltage optimisation and energy saving should be at the forefront of their strategy.
