With dynamic
VO, incoming voltage is monitored continuously and adjusted in real-time, enabling supply to be maintained as close as possible to the ideal nominal voltage. There is no need to interrupt the load for adjustments, and a minimum optimised voltage can be guaranteed –making it particularly suitable for sites operating sensitive equipment
lines. The ROI on VO can be compelling when improved energy efficiencies can ºbe demonstrated and reduced production downtime or maintenance are factored in.
There are two main choices when selecting a VO solution. Fixed VO reduces supply to a set level. Here, any adjustments to output can only be made when the system is electrically isolated. While this more traditional VO technology offers some benefit, energy savings can be limited when the percentage reduction in voltage is fixed. Fixed VO doesn’t provide the flexibility of modern, dynamic VO.
such as CNC, or where demand varies or fluctuations are particularly prevalent. With dynamic VO, site consumption and energy savings are visible in real time, providing greater insight to help energy managers make better-informed decisions.
Where Powerstar has established that VO is a viable and efficient recommendation for customers, the typical payback period is between two and five years, with immediate savings on energy spend – between 5 and 8%, on average. For theWernick Group, a company committed to sustainable manufacturing, Powerstar
installed two VO units which have reduced energy
consumption by 9.2%, equating to 19 tonnes CO2 saved each year, and generating cost savings of approximately £18,000 p.a. At M I Dickson, the largest family-owned food manufacturer and retailer in the Northeast, our site survey showed unstable, overly-high voltage supply. Introducing dynamic VO has reduced energy consumption by over 8,000 kWh (despite production volume increasing by 10%). The company is using 52.8 kWh fewer per tonne of product, and VO has generated energy savings of 13%.
For any business considering VO, an initial discussion with a potential supplier should give you an indicative ROI, based on your business and site specifics. A subsequent full site survey, undertaken by a specialist who can scope installation requirements, will enable them to gain a thorough understanding of your site profile and provide a detailed voltage log, with accurate projections of
savings in kWh, CO2, and payback time. Ultimately, VO isn’t appropriate for every
business. But, where it offers energy savings – when specified correctly for each site profile – it delivers efficiently, and effectively.
