If buildings shifted one third of their peak electricity consumption to the middle of the day, this would save $1.7 billion annually and add additional peak capacity equivalent to 52% of Australia’s existing coal generation fleet. It would reduce Australia’s greenhouse gas emissions from electricity by 1.9% (2,780,000 tonnes) per year and accelerate decarbonisation by encouraging more renewable energy investment.

In order to pursue such potential benefits governments should measure and incentivise demand flexibility in buildings.
