The NSW Office of Environment and Heritage has released a guide on voltage optimisation for businesses wanting to improve energy efficiency.
The voltage optimisation helps businesses determine if the technology will benefit their site, as well as dispel common misconceptions.
Voltage optimisation works by adjusting voltage supplied to a site. This can better meet the requirements of certain equipment and lights, resulting in improved equipment life and reduced energy use.
Deputy chief executive of the NSW Office of Environment and Heritage Ian Hunter said VO technology was fairly well-known overseas though relatively new to Australia.
“Internationally, voltage optimisation has been shown as a useful option for businesses to reduce their energy use and improve equipment life,” Mr Hunter said.
“It is safe, proven technology, and you are not alone when examining your options. We’re here to help you.
“On optimal sites, some businesses have seen energy savings of up to 12 per cent or more.
“The effectiveness of the technology really depends on a site’s equipment, operational requirements and voltage supply.
“The value of this guide is in helping businesses decide whether it’s worthwhile for them to invest in voltage optimisation.”
An early adopter of the technology in Australia is hotel group Accor.
Chief engineer of Accor’s Sydney Olympic Park hotels Michael Cook said the technology had achieved a 7.7 per cent saving in overall energy use across its Novotel and Ibis venues.
“Voltage optimisation can be quite complicated to implement as there are many things that need to be weighed up, but the benefits of it are worthwhile,” Mr Cook said.
“Not only have we saved on our total energy use, voltage optimisation has enabled us to reduce our peak time consumption, meaning we’re consuming less power when it is at its most expensive.”
The guide provides a five-step framework for decision-making, as well as a toolkit of checklists and business templates that simplify each step.
An accompanying e-learning course will also be developed as a companion to the guide, enabling business owners and managers to work through the decision-making process interactively. It is expected to be launched in April.
