Summary

United Energy will use voltage control devices installed at substations across its entire distribution network to deliver demand response (DR) as a participant of the Demand Response initiative. The United Energy Distribution Demand Response project will deliver 12 MW of DR reserve from 1 December 2017, increasing to 30 MW of DR reserve in years 2 and 3.

How the project works

The United Energy Distribution Demand Response project works by slightly reducing the voltage at substations across its network in Melbourne and the Mornington Peninsula. By using smart meter voltage data at customer substation locations, United Energy will be able to ensure the reductions are done in a precise and controlled manner. The voltage will be reduced by an average of 3 per cent during peak demand surges, where appliances are able to continue being used. By only running the system at low voltages for short and controlled periods of time, United Energy can provide AEMO with reserve without harming their systems.

Area of innovation

While a relatively simple idea, the project is innovating how we can look to leveraging the available voltage range from smart-meter measurements to keep supply to customers within the allowable voltage limits as a way to stabilise the grid in peak demands – without having to ask consumers to reduce their energy usage.

Benefit

The program will help to establish whether DR can assist in maintaining a stable electricity grid in Eastern Australia.
