Melbourne's Net Zero Push Hits a Critical Week: New Targets, Funding Fights and a CBD Solar Milestone

Victoria's net zero agenda lurched forward on two fronts this week. The state government confirmed Thursday that the Victorian Renewable Energy Target — set at 95 per cent by 2035 — will be backed by a further $180 million in grid storage contracts, even as Labor faces mounting pressure from industry groups who say the rollout of rooftop solar incentives is being strangled by bureaucratic delays at Solar Victoria, the state agency managing rebate applications.

The timing matters. With federal carbon accounting periods kicking in from January 2027 and Melbourne's own Zero Carbon Buildings standard scheduled for mandatory enforcement on commercial properties from 1 September 2026, developers, councils and community groups are all watching the same clock. Delay now means penalty exposure later — and the property market, already jittery with falling prices and cautious first-home buyers sitting on their hands, can ill afford another regulatory headache.

Fitzroy to Fishermans Bend: What's Actually Moving

The most concrete achievement this week came from the City of Yarra. Its council confirmed that more than 60 per cent of residential rooftops across Fitzroy, Collingwood and Abbotsford now carry solar panels — the highest street-level saturation of any inner-urban municipality in the country, according to data compiled by the Australian PV Institute. That milestone was partly driven by the Yarra Zero Carbon program, a council-administered top-up rebate that has been running since 2023 and has processed just over 4,200 applications.

Across town, the Fishermans Bend urban renewal precinct — Australia's largest urban infill project at 485 hectares — is wrestling with a different problem. The Melbourne Fishermans Bend Authority wants every new build in the Montague and Lorimer quarters to be all-electric from the ground up, but gas connections are still being approved on some lots under grandfather provisions that critics say the state government has been too slow to abolish. The Electrical Trades Union lodged a formal complaint with the Department of Energy, Environment and Climate Action on Tuesday, arguing the inconsistency is costing their members planning certainty on contracts worth an estimated $340 million across the precinct through 2028.

The CFMEU, whose relationship with the state government remains combustible on multiple fronts, has separately flagged that green retrofit work on older commercial buildings along Flinders Lane and Collins Street is generating significant member hours — but that union-endorsed training for heat-pump installation is still under-resourced, with only three registered training organisations in Victoria currently certified to deliver the relevant Certificate III pathway.

The Numbers Behind the Ambition

Victoria's own data is both encouraging and sobering. The state hit 36 per cent renewable electricity generation in the 2024–25 financial year, up from 28 per cent the year before, driven largely by the Bulgana Green Power Hub and the Western Renewables Link transmission project running from Bulgana to Sydenham. But building emissions — covering heating, cooling and hot water in homes and offices — remain stubbornly flat, accounting for roughly 53 per cent of Melbourne's total municipal carbon output, according to figures published by the City of Melbourne's Environment Portfolio in March 2026.

The Allan government's flagship Home Energy Upgrade package, which provides interest-free loans of up to $10,000 for households to switch from gas appliances to electric alternatives, received 11,400 applications in its first six months. The scheme's allocated budget will be exhausted by October at current take-up rates, raising questions about whether a top-up will appear in the mid-year budget update expected in December.

For residents and businesses trying to navigate this week's developments practically: Solar Victoria's rebate portal is currently quoting a 14-week processing time for standard residential applications, down from 22 weeks in March. The City of Melbourne's Zero Carbon Buildings team is running free compliance workshops at the Town Hall annex on Swanston Street through July, with the next session booked for July 15. Developers in Fishermans Bend have been advised to seek written confirmation of their gas connection status before lodging any further permit applications — a workaround that is hardly elegant, but is currently the only way to avoid being caught in the middle of a dispute that state and local governments have not yet resolved.
