Voltage Management Trial

Jemena recently carried out a voltage management trial in Airport West and Coburg South to test new technology that regulates the voltage of electricity supplied to homes and businesses as more rooftop solar is installed across our electricity network.

The trial tested the use of Volt-Var Control (VVC) which is a dynamic voltage management technology that ensures voltages remain within the required range and helps protect the power quality of the network.

The trial wrapped up in August 2024 and successfully demonstrated that this new technology can maintain electricity supply voltages when faced with voltage fluctuations caused by growth in rooftop solar. This means that more of our customers will be able to install solar with without causing voltage issues or experiencing limits to the amount of excess electricity they can export back into the grid.

The technology is now ready to be rolled out across Jemena’s electricity network and planning for this is underway.
