- Project PartnersNoneThis demand response project was completed on 2 December 2020.
United Energy uses voltage control devices installed at 47 zone substations across its distribution network to deliver demand response (DR) as a participant of the Demand Response initiative. The United Energy Distribution Demand Response project delivered over 150 MW of DR reserve during the three-year trial.
- Previously, the use of voltage control to provide demand response services has presented a level of risk as it could not be guaranteed that customer voltages would not fall below the stipulated regulated limits, which in turn risks household appliance damage.
- United Energy has addressed this risk by developing an advanced technique using smart meters to implement voltage reduction without deteriorating their regulatory voltage compliance.
- Voltage across the network can be reduced by 3% on average to deliver at least 30MW of demand response within 10 minutes when called upon, sustained over a 4-hour period between 10am and 10pm on business days.

How the project works
The United Energy Distribution Demand Response project used the existing fleet of smart meters deployed across the distribution network in Melbourne and the Mornington Peninsula to provide time-lagged customer voltage data from all connected smart meters to enable reductions in voltage while maintaining voltage compliance during the demand response event.
Area of innovation
While a relatively simple idea, the project innovated how the industry can leverage 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.
The program helped establish the idea that DR can assist in maintaining a stable electricity grid in Eastern Australia.
United trial fine tunes Victoria’s grid stability
As temperatures soared across Australia’s south-east in late January this year, Victorian distributor United Energy activated a novel approach to demand response.
EDITORIAL: The Distributed Energy Revolution
If millions of Australian households and businesses continue to invest in their own solar and battery systems, this vast array of small scale energy assets known as Distributed Energy Resources (DER) could create enormous disruption to the electricity system.
ACCC calls for “reset” of electricity market, backs demand response
The Australian Competition and Consumer Commission (ACCC) has released its final report on electricity prices on Wednesday, calling for reforms to overhaul what it dubbed a “broken” electricity market.
