Residential electrification has reduced gas demand in Australian state Victoria by around 5.6 petajoules per year, while cutting energy bills by around AU$185 million ($130.04 million) since 2023, the Institute for Energy Economics and Financial Analysis said Thursday.
"By cutting gas demand through electrification, Victoria can mitigate against the risk of future gas supply gaps while lowering energy bills," IEEFA said. "By contrast, importing more gas into Victoria carries significant infrastructure costs that would need to be added to consumer bills."
The reduction in gas consumption is equivalent to 10.5% of demand from large commercial and industrial users, the institute noted.
If electrification continues at recent rates, IEEFA projects that 2040 gas demand will be reduced by 40 PJ/year, which is more than the combined annual consumption of the state's mining and power generation sectors. Household savings could grow to AU$6.6 billion by the same period.
"While the savings are considerable, they come with a note of caution: Existing policies alone cannot fully mitigate the risk of future gas supply gaps," IEEFA said, adding that new regulations, such as those set to begin in 2027, have to be successfully implemented to accelerate electrification.
