    This demand response project was completed on 14 August 2019.


The Zen Ecosystems Demand Response project will see Zen Ecosystems deploy its “smart” connected thermostats across Victoria and South Australia, to aggregate and control heating and cooling within commercial and residential buildings. The project will aim to deliver 5 MW of demand response reserve from 1 December 2017, increasing to 15 MW of demand response reserve in year 3.

How the project works

The Zen Ecosystems Demand Response project will deliver its reserve through direct load control, where air conditioning, heating and ventilation can be automated by ZenHQ using a network of connected thermostats across Victoria and South Australia in the commercial and residential customer segments. Residential customers are also able to participate in a behavioural demand response program to voluntarily contribute to managing their energy usage during peak demand.

Area of innovation

The automated, “smart” and connected Zen Thermostat is an innovative approach to reducing peak loads on an energy network. Zen, an Australian company, trialled this approach successfully in the United States, where it was able to show energy savings of between 10-30%.


The program will help to establish whether demand response can assist in maintaining a stable electricity grid in Victoria and South Australia.

The demand response army of customers that's 1.7 million strong...

When you join forces with a big operator and work together on a really big idea, the results you tend to get are, well…

Zen and the art of demand response (or how to stay cool about staying cool this summer)

It’s a small black or white box, elegantly yet simply designed, and it could be in your home soon, making a difference not just to your own electricity bill but helping to secure the system as a whole.
