Power bills top Australians' data centre worries, poll finds

At a glance

• In a DemosAU survey for Capital Brief, 68 per cent of voters expected a local data centre to raise power prices, the highest of five effects tested.

• Only 23 per cent think Australia should aim to lead the world in hosting data centres, a Capital Brief/DemosAU poll published on 2 November 2026 found.

• Regulated household power prices fell in NSW, south-east Queensland and Victoria on 1 July 2026, and rose 1.4 per cent for flat-rate households in South Australia.

• One bill increase before the energy regulator comes from a transmission line: Transgrid's bid to recover A$1.2 billion of extra costs on EnergyConnect.

• Climate Change and Energy Minister Chris Bowen has asked for rules making data centres contribute to the network costs they cause and back their demand with firmed supply.

Only 23 per cent of Australian voters think the country should aim to be a world leader in hosting data centres, according to the Capital Brief/DemosAU poll published on 2 November 2026, and 38 per cent said the negatives of data centres outweighed the positives, Capital Brief reported. In a second report, it said 44 per cent saw no real benefit for ordinary Australians. Greens senator Sarah Hanson-Young, whose party wants a moratorium on new data centres until national rules are in place, cited the poll in an episode of her podcast published on 2 November 2026.

An earlier DemosAU survey for Capital Brief asked 1,562 voters in August 2026 what a data centre built in their area would do. Electricity prices drew the strongest response, with 68 per cent expecting them to rise.

So far, household bills have moved the other way. Regulated power prices fell in NSW, Victoria and south-east Queensland on 1 July 2026, and a bill increase now before the energy regulator comes from a transmission line overrun rather than data centres. Power prices could rise, as voters fear, if data centres connect without new supply or leave network costs with other users, and the rules Climate Change and Energy Minister Chris Bowen has requested aim to stop both.

Voters expect higher power prices and more jobs from a local data centre

DemosAU asked voters what a data centre in their area would do to electricity prices, pollution, long-term jobs, economic growth and local quality of life. Almost half expected jobs and growth to rise.

In the August survey, 30 per cent of voters said more data centres would be good for Australians, 32 per cent said bad and 38 per cent were neutral or unsure. DemosAU said the issue does not yet generate the hostility seen in the United States. Coalition voters rated more data centres as good on balance by a net 25 points and Labor voters by 12, while Greens and One Nation voters were net negative. Regional and rural voters were net negative at minus 15, against plus 8 in inner metropolitan areas.

Household power prices fell in three states on 1 July 2026

The Australian Energy Regulator (AER) cut its default market offer, the capped price for households on standard plans, by 3.4 to 5 per cent for flat-rate households in NSW and 7.2 per cent in south-east Queensland. The Victorian Default Offer fell about 5 per cent, and South Australia's cap rose 1.4 per cent for flat-rate households.

In the United States, a June 2026 study by researchers at the Electric Power Research Institute, a US industry research body, found data centres modestly lowered average power rates between 2015 and 2024, partly by spreading the grid's fixed costs over more demand. Its authors warn that tight supply could reverse that. Assistant Minister for Science, Technology and the Digital Economy Andrew Charlton has made a similar case for Australia. The Smart Energy Council, the renewable energy industry's peak body, estimates that households would pay about A$9 billion more over six years if 5GW of data centres connected without new clean power and storage.

Transgrid's EnergyConnect claim could add A$18 to household bills in 2027-28

One bill rise now before the AER comes from a transmission line. Transgrid, which owns NSW's high-voltage grid, wants to recover A$1.2 billion of extra costs on EnergyConnect, the line linking South Australia, NSW and Victoria. That would add about A$18 to a typical bill in 2027-28, The Australian reported on 3 November 2026.

Transgrid says the failure of the joint venture contracted to build the line was beyond its reasonable control. The AER's preliminary view, published on 1 September 2026, is that Transgrid has not met the test to reopen what it can charge customers, though costs the AER judges prudent and efficient could still be recovered in its 2028-33 revenue ruling. Retailers AGL Energy and Alinta Energy have backed the AER.

Proposed rules would put grid and supply costs on data centres

The rule changes Bowen has requested cover both price risks, network costs and new supply.

• Network costs. Requests lodged on 22 July 2026 would make data centres and other large users contribute to the network costs they cause. The Australian Energy Market Commission (AEMC), which makes the national electricity rules, is due to publish its draft determination by 1 April 2027.

• New supply. A request lodged on 20 October 2026 proposes that data centres above a size threshold, yet to be set, prove, before connecting, that their demand is backed by new generation, storage or the ability to cut use at peak times in the same region. Without that, Bowen's request says, the costs "could be borne by consumers".

• States and National Cabinet. NSW's network cost reforms rest on a bill that passed its lower house on 15 September 2026, and National Cabinet intends to legislate national data centre standards in early 2027.

States regulate backup diesel generators and noise

Sixty per cent of voters expect a local data centre to increase pollution, and that concern has a basis. Backup diesel generators run for testing and during outages, and Australia has no national emissions standard for them, the Centre for Safe Air, a research centre funded by the National Health and Medical Research Council, told the NSW parliamentary inquiry into data centres. NSW sets emission limits and health-based air criteria, and Victoria's new data centre plan would limit the generators to emergencies and mandatory tests. NSW assesses data centre noise under the same industrial noise policy that applies to warehouses and cold stores.

Data centres support 9,450 jobs, with 23,040 forecast by 2030

Operating data centres in Australia support about 9,450 ongoing jobs and A$2.3 billion of economic activity a year, according to modelling by consultancy Mandala for Data Centres Australia. Mandala forecasts 23,040 ongoing jobs by 2030, plus 18,930 construction jobs to build the pipeline.

The jobs on site are few once a campus is running. Townsville City Council told the Senate inquiry a facility may need only five or six staff to operate, with the larger value in the businesses and investment around it. A study of more than 1,500 US data centres found host areas gained about 2.7 jobs outside construction for every megawatt of eventual capacity, with the gains appearing three to five years after opening, Fortune reported.

Hanson-Young's conditions overlap with the national standards on power and water

Hanson-Young set four conditions for the sector on ABC's Insiders on 9 August 2026: power bills that do not rise, protected water, protected jobs and community benefit. The standards National Cabinet has agreed to develop cover data centre energy, water and land use. Industry and Science Minister Tim Ayres pushed back on a pause in July 2026, saying the national expectations for data centres were being worked through with the states.

Hanson-Young chairs the Senate committee inquiring into AI and data centres. In a progress report on 20 October 2026, the committee moved its reporting date to 23 March 2027.

Data centres use under 1 per cent of Sydney's water

Water was not on DemosAU's list, but it is one of Hanson-Young's conditions, and Sydney's forecast gives it a real basis. Sydney's data centres account for less than 1 per cent of Greater Sydney's water demand, Sydney Water says, but could add up to 20 to 25 per cent to the city's total demand by 2035, though that need not come from drinking water, W.Media reported. NSW's pricing regulator is set to examine how data centres should pay for the water infrastructure built to serve them.

Nationally, data centres use about 0.04 per cent of Australia's distributed water, on CSIRO figures. AWS will cool its new western Melbourne data centre with recycled water from day one.

What to watch

• The network cost rules. Submissions to the AEMC close on 5 November 2026, and its draft determination is due by 1 April 2027.

• Bowen's new supply request. The AEMC has yet to begin consultation on the 20 October 2026 request.

• The EnergyConnect decision. The AER took submissions on its preliminary position until 1 October 2026 and has yet to publish its final decision.

• The national standards. National Cabinet intends to legislate the standards for data centre energy, water and land use in early 2027.

• The Senate inquiry. The committee's report is due on 23 March 2027.
