UK Power Networks is trialling a technology that maximises the use of existing low voltage cables rather than build anew allowing for a more localised power distribution.

Partnering with Ecojoule Energy and Fundamentals, the EcoVAR trial will see five units installed including smart, pole-mounted devices , to keep the network balanced and 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. Installed on existing poles, the device can be up and running within hours.

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.
