Australia Faces Decade of High Electricity Prices Despite Net Zero Push

Despite a commitment to net zero emissions,Australian households are bracing for at least another decade of elevated electricity prices,according to warnings from the nation’s energy chiefs. A recent survey conducted by the Australian energy Council (AEC) reveals widespread concern among industry leaders that unavoidable costs associated with the energy transition are yet to be fully reflected in consumer bills.
The AEC, representing major players like AGL, Origin, and Energy Australia, found that planned expansions to the electricity network – specifically poles and wires – are a important driver of these anticipated cost increases. “I think it’s the calm before the storm, and… the storm is coming around cost and competitiveness,” one chief executive reported. Another executive cautioned that costs for network infrastructure are poised to “go up and go up by increasing levels,” with consumers largely unaware of the scale of the challenges ahead.
While the increasing adoption of renewable energy sources has recently exerted downward pressure on electricity generation costs, the expense of maintaining and upgrading the existing grid, and building new infrastructure to support renewables, is expected to offset these savings.
Ms. Kinnear, head of the AEC, emphasized that her members “understood the urgency of climate change and the role of the energy industry in meeting our emissions ambitions.” She echoed the sentiment that replacing aging coal-fired power stations is inevitable.
“The AEC supports the transition to net zero emissions by 2050 on the premise that the least-cost, lowest-impact pathway is an energy system dominated by renewables,” Ms. Kinnear stated. Research from the CSIRO and international energy experts consistently supports this view, with the International Energy Agency recently finding that pursuing net zero by 2050 would ultimately benefit consumers compared to a slower approach.
A Decade of Price Pressure
However, Ms. Kinnear stressed that significant investment will be required to build new generation capacity, expand transmission and distribution networks, and implement necessary backup systems. This investment will inevitably impact consumer bills. “We need to ensure that clean, affordable energy remains accessible to everyone during the transition,” she said. “Replacing ageing, emissions-intensive generation with predominantly renewable energy is not costless.”
Several chief executives, speaking anonymously, expressed more direct concerns. one stated that “the most urgent issue… is addressing affordability.” Another warned that the public is “not really wise” to the true cost of the transition, anticipating that “power bills will go up for a while before they go down.” They also noted that promises of bill reductions from governments are unlikely to materialize in the near future.
Concerns were also raised about broader challenges hindering the transition, including escalating construction costs, local opposition to projects, and political instability. Delays in constructing new transmission lines and large-scale wind and solar farms could jeopardize the reliability of existing fossil fuel plants. Some CEOs suggested that coal closures may even need to be postponed, possibly requiring taxpayer funding to keep older plants operational.
“The transition right now is delicately poised and at quite an important point,” said a leader from a generation and retail company. “There have been these bumps along the way, it is taking longer to deliver the new generation and transmission projects [and] transmission is obviously a critical path.”
Network Costs and Broader Pressures
Energy Networks Australia, representing poles and wires companies, cautioned against solely attributing cost pressures to transmission projects.CEO Dominique van den Berg highlighted that rising interest rates, labor costs, and material demands are also contributing factors. She emphasized that replacing aging infrastructure is “no longer optional,” but “essential,” and represents a primary driver of new investment. “Even in this environment, transmission lines are still a relatively small share of a household bill.”
Despite these challenges, Ms. van den Berg reiterated that a combination of renewables, storage, and gas remains the most cost-effective and environmentally sound solution for replacing retiring coal plants.
The path forward remains complex, but one thing is clear: Australian consumers should prepare for a sustained period of high electricity prices as the nation navigates its ambitious, yet costly, energy transition.
