From driveways to rooftops, renewable energy is reshaping how we use electricity, and distribution network operator UK Power Networks is now deploying a new device to support the adoption of low-carbon technologies on traditional electricity networks.
To help customers adopt clean technologies like electric vehicles and solar panels without delays, UK Power Networks is trialling a new technology that maximises the use of existing low-voltage cables rather than build anew.
The company has partnered with Ecojoule Energy and Fundamentals to deploy new smart EcoVAR units that balance electricity on local networks, reducing the need for costly new infrastructure.
How the tech works
The initiative will see five EcoVAR units – which are smart, pole-mounted devices – installed that keep the network operating efficiently at the low-voltage level, where most homes and businesses are connected.
The technology works by managing the flow of electricity across the network’s three separate lines, known as phases. Sometimes one phase can become overloaded while others are underused.
The EcoVAR unit automatically redistributes electricity to the quieter lines, helping the network accommodate more clean-energy technologies without spending customers’ money on infrastructure where it is not needed.
Installed on existing poles, the device can be up and running within hours.
Trials in place
The first unit has been installed in Graveney Bridge, Kent, with data collected during the trial being used to assess how effectively the system improves network efficiency.
Each unit is monitored and updated remotely, allowing for smarter management of power flows.
The trial will also test the unit across different weather conditions, helping to ensure that as low-carbon technologies become widespread, electricity networks remain resilient, flexible, and ready for the future.
Luca Grella, Head of Innovation at UK Power Networks, notes, “Being the first to install this kind of technology in the UK highlights our commitment to working with partners who share our vision for a smarter, more resilient grid.
“The EcoVAR trial is helping us understand how digital solutions can deliver real improvements for customers at street level.”
Colin Relf, Treasurer of Graveney & Goodnestone Village Hall, is delighted the community is part of the trial, stating, “The EcoVAR device has been a godsend.
“Export was very unreliable, preventing a much-needed income that, without it, could have ultimately led to the Village Hall closing. It provides peace of mind and security for supplying back onto the grid.”
