Australian household electricity prices rise nearly 8% in two years amid debate over transition costs

Australian households are facing a sharp rise in electricity costs, with new analysis showing retail prices climbed nearly 8 percent over the past two years and are increasing faster than general inflation.

Energy comparison service iSelect found the average household electricity price rose from 36.1 cents per kilowatt-hour in June 2023 to 38.9 cents in June 2025. That increase outpaced Australia’s headline inflation rate of 2.1 percent recorded in July, placing additional pressure on household budgets already strained by higher living costs.

Economists and industry analysts point to a mix of factors behind the rise. MacroBusiness chief economist Leith van Onselen said the transition from baseload coal to weather-dependent wind and solar has raised network and system costs that are ultimately carried by consumers. He cited transmission upgrades, the capitalisation of those investments into the regulatory asset base, and greater reliance on gas, batteries and pumped hydro to firm intermittent generation as drivers of higher bills.

"Labor lied when it promised that power bills would fall," van Onselen said, referring to a 2022 pledge by the Albanese government to deliver a A$275 cut to household power bills under its climate plan. He argued the costs of transmission and subsidies for renewables are being passed to households and that industries benefiting from the transition are capturing rents while renters, pensioners and low-income households bear the costs. Van Onselen also highlighted Australia’s extensive coal and uranium exports and argued that a domestic policy shift has limited global emissions impact given Australia’s roughly 1 percent share of global emissions.

Not all observers agree with that diagnosis. The Clean Energy Council’s policy chief, William Churchill, pointed to the federal government’s recent climate assessment, which warned that rising seas could put millions of Australians at risk of losing homes, and said those risks underscore the need to accelerate the deployment of clean energy. "The need to prepare and act is now beyond question," Churchill said, adding that faster rollout of renewable projects is central to keeping long-term costs and climate risks in check.

An Institute for Energy Economics and Financial Analysis analyst, Jay Gordon, said household-level responses could offer substantial relief. Gordon argued that upgrading household energy systems — including rooftop solar, batteries and efficiency measures — could cut electricity bills for a typical home by 80 to 90 percent. He said rapid solar uptake has driven daytime wholesale prices to record lows, but a combination of rising fossil fuel prices, high network costs and an ageing generation fleet has kept retail bills high.

Gordon described recent policy responses as dominated by short-term measures, including one-off bill subsidies, and said a stronger focus on household upgrades would reduce both bills and emissions while strengthening grid resilience. He welcomed federal battery rebates but said they missed an opportunity to include other thermal and efficiency upgrades that lessen grid demand.

Banks and market analysts have also documented the household impact. Commonwealth Bank of Australia’s August Household Spending Insights report recorded a 2.9 percent increase in utilities spending, the largest hit to household budgets among the categories it tracks.

Regional differences are shaping the debate. Van Onselen pointed to South Australia — where wind and solar supply roughly three-quarters of generation — as an example of high renewable penetration coinciding with high retail prices. Industry groups and grid planners, however, say high retail prices in some regions reflect historical contracts, network charges and the costs of replacing retiring generation as much as the generation mix itself.

Policymakers are wrestling with trade-offs between speed of the clean energy rollout, network investment, and measures to shield vulnerable households from higher short-term costs. The federal government has introduced measures such as rebates for home batteries and targeted bill relief, while grid operators and transmission developers plan large-scale investment to connect dispersed renewables and provide firming capacity.

Analysts say the near-term outlook for household bills will depend on policy settings, the scale and timing of transmission and firming investments, wholesale fuel prices and how quickly households adopt on-site generation and storage. Industry and consumer advocates highlight that reducing the amount of energy households draw from the grid — through efficiency and smart-use measures — is a direct way to reduce costs.

The conversation has expanded beyond immediate bill impacts to include long-term questions about energy security, industrial competitiveness and emissions. Proponents of faster renewables deployment argue it is essential to limit climate risks and reduce future costs of fossil fuel dependence, while critics emphasise the current distribution of costs and call for diversified approaches, including consideration of nuclear or greater use of domestic fossil fuels, positions that remain politically and technically contentious.

As Australia continues its shift away from ageing thermal generators, the balance between investment in networks and firming resources, consumer-facing support for upgrades, and regulatory choices about how costs are recovered will shape household bills in the years ahead. Policymakers face pressure to manage the transition so that energy remains reliable and affordable while meeting national emissions targets and climate resilience needs.
