By the numbers: What Ballarat's sustainability push actually looks like on the ground

Ballarat has cut its corporate greenhouse gas emissions by roughly 38 percent since 2015, according to data published by the City of Ballarat in its most recent annual sustainability report. That number sounds encouraging. The harder figure sits underneath it: the municipality still generated an estimated 1.4 million tonnes of carbon dioxide equivalent across the broader community in the last measured year, and the council's own net-zero target is 2030.

Four years is not long. The gap between the headline win and the work remaining has become a live political question in Ballarat, particularly as state and federal budget decisions on renewable infrastructure pile up through mid-2026. Victoria's broader push to reach 95 percent renewable electricity by 2035 depends heavily on regional areas carrying the load — transmission corridors, wind easements, community battery programs — and Central Highlands communities are already feeling the land-use tension that comes with that.

Solar, batteries and what's actually installed

The uptake numbers at the household level are striking. As of June 2026, more than 14,800 rooftop solar systems had been registered across the City of Ballarat local government area, representing an installed capacity above 78 megawatts. That is roughly double the figure recorded five years ago. The Wendouree and Sebastopol postcodes — traditionally the city's more affordable housing corridors — account for a disproportionate share of new installs, largely driven by the federal government's expanded Household Energy Upgrades Fund, which offered low-interest loans of up to $30,000 for eligible owner-occupiers.

Community batteries are a different story. Ballarat currently has two operational community-scale battery assets: one at the Ballarat Aquatic and Lifestyle Centre on Gillies Street North, commissioned in late 2024 with a 500 kilowatt-hour capacity, and a second smaller unit associated with the Delacombe Town Centre precinct. A third, proposed for the Sebastopol Library site on Albert Street, has been in planning since early 2025 and remains unfunded. The council applied to the Australian Renewable Energy Agency's Community Batteries for Household Solar program in February 2026; a decision has not yet been announced.

Waste data tells a more complicated story. Ballarat's landfill diversion rate — the share of collected waste that does not end up at the Lucas Street Transfer Station and ultimately the regional landfill near Smythesdale — was 52 percent in 2024-25. The state government's Recycling Victoria policy framework set a target of 80 percent diversion by 2030. At the current trajectory, independent modelling cited in council documents suggests Ballarat would reach around 61 percent by that date without significant additional intervention.

Where the money is going — and what's still missing

The City of Ballarat allocated $4.2 million to sustainability-related capital works in its 2025-26 budget, up from $2.8 million the year before. The largest single line item was $1.6 million for LED street lighting upgrades across the CBD and the Sturt Street boulevard, a project that council officers say will reduce street lighting energy costs by approximately $340,000 annually once complete. Work on that project began in March 2026 and is scheduled to finish before Christmas.

What's harder to track is the private and community investment flowing through programs like Sustainability Victoria's Energy Local grant stream, which funded the Ballarat Community Energy cooperative's feasibility work for a proposed 2-megawatt solar farm on the city's northern fringe. That project is still in a development application phase with the council as of this week.

Residents wanting to engage with what's coming next have a practical near-term option. The City of Ballarat is running a community consultation session on its updated Climate Emergency Action Plan at the Mining Exchange on Lydiard Street North on July 16, from 5:30pm to 7:30pm. Submissions to the plan close on August 8. Council officers say the updated plan will, for the first time, include annual interim targets rather than a single 2030 endpoint — which would make it easier to measure, year by year, whether the gap between the good-looking headline number and the harder one underneath it is actually closing.
