"Gas connections for all new housing and sub-divisions will be banned in
Victoria from January 1 next year. The long-term result of the state
government’s significant change to planning approvals will be all-electric
housing. The ACT made similar changes early this year, in line with a shift
away from gas across Europe and other locations, although the NSW Premier Chris
Minns has baulked at doing the same.
Around 80% of homes in Victoria are connected to gas. This high uptake was
driven by gas being seen as more affordable and sustainable than electricity
over past decades. The situation has changed dramatically as renewable
electricity generation increases and costs fall.
Research has suggested for more than a decade that the benefits of all-electric
homes stack up in many locations. New homes built under mandatory building
energy performance standards (increasing from 6 to 7 stars in Victoria in May
2024) need smaller, cheaper heating and cooling systems. Installing
reverse-cycle air conditioning for cooling provides a cost-effective heater as
Savings from not requiring gas pipes, appliances and gas supply infrastructure
help to offset the costs of highly efficient electric appliances. Mandating
fully electric homes means economies of scale will further reduce costs."
