The Australian government’s Capacity Investment Scheme (CIS), launched by the Labor administration to support the development of large-scale renewable energy projects, has so far yielded limited operational results, raising concerns about its effectiveness and potential financial risks. Since its inaugural auction in 2023, the scheme has funded 94 projects; however, only one— a 46-megawatt solar farm in Victoria— is currently operational. Of the projects announced, 35 are under contract, with just 15 reaching a final investment decision.
Opposition energy spokesman Dan Tehan has voiced significant apprehension over the slow progress of the CIS, warning that the sluggish pace could jeopardize the government’s goal of achieving 82 percent renewable electricity by 2030. The target, integral to Australia’s energy transition ambitions, was notably omitted from a preliminary draft of Labor’s national policy platform ahead of the next federal election scheduled for 2028. Despite this, the government continues to emphasize the role of wind and solar energy in reducing electricity costs and revitalizing domestic industries while attributing grid instability to coal power.
Financial concerns surrounding the CIS escalated following the May federal budget, with critics describing the program as a “potentially multibillion-dollar green debt bomb” concealed within the budget’s contingent liabilities. These liabilities, including the CIS and the Snowy 2.0 hydroelectric project—which has experienced significant cost overruns—are not fully disclosed due to commercial sensitivities. As a result, the true fiscal impact on taxpayers remains uncertain, with potential liabilities likely to materialize over time.
Energy Minister Chris Bowen defended the scheme, stating that many CIS projects are expected to come online closer to the decade’s end, characterizing the rollout as non-linear. Bowen also attributed the previously limited pipeline of investment-ready renewable energy projects to the prior government, accusing former Energy Minister Angus Taylor of failing to adequately support renewables. Bowen further criticized the Coalition’s approach as one focused on preserving coal and leaving households to bear higher costs.
At a recent Senate estimates hearing, officials from the Clean Energy Council reported that the volume of green energy projects reaching financial closure has declined to the lowest level in a decade. Department of Climate Change, Energy, the Environment and Water deputy secretary Matthew Brine noted that while batteries and solar projects are progressing well under the CIS, wind energy developments face multiple challenges, including rising turbine costs and social licence issues related to transport and community acceptance. Brine emphasized that all forms of energy generation must remain financially viable.
Meanwhile, calls for a broader market-based approach to energy project financing have been voiced. Nationals leader Matt Canavan, speaking at a NSW Nationals conference, criticized financial institutions for effectively acting as gatekeepers by restricting funding for coal and gas projects. Canavan argued that this has hampered the sector’s ability to meet rising energy demand, including from growing AI data centre operations, and claimed that some lenders are declining finance for agricultural businesses that do not align with net-zero targets.
As the government continues to navigate the complexities of its renewable energy transition, questions persist around the CIS’s long-term impact on both Australia’s energy capacity and public finances.
