Snowy 2.0 was never going to be cheap. But it will be much cheaper than relying on batteries for storage
The final cost assessment for the Snowy 2.0 pumped hydro project has been released, estimating total expenditure between A$22 billion and A$25 billion with completion expected in late 2029. This figure represents a significant increase from the initial A$2 billion estimate provided by former Prime Minister Malcolm Turnbull in 2017, attributed to engineering challenges, tunneling delays, and rising construction costs. Despite criticism regarding budget overruns, the article argues that the project is approximately 80 percent complete and offers superior long-term value compared to alternatives. Specifically, building equivalent grid-scale battery storage would cost three times more upfront, whereas the hydro facility is designed to operate for 150 years compared to the typical 20-year lifespan of lithium-ion batteries. The infrastructure is positioned as essential for meeting Australia's target of 82 percent renewable energy generation by 2030, particularly to address overnight electricity demand as aging coal-fired power stations retire.
Alinta Energy has withdrawn plans for a $1.8 billion pumped hydro energy storage scheme in northern New South Wales, citing economic and timing challenges associated with critical transmission lines. The 900-megawatt Oven Mountain project, located near the rural hamlet of Carrai, was one of the largest initiatives within the Armidale Renewable Energy Zone. An Alinta Energy spokesperson stated that the decision followed years of technical studies, planning, and stakeholder engagement. The withdrawal marks the second failure of a state-significant renewable energy project this month, following Origin Energy’s scrapping of the proposed 870-megawatt Skye Ridge Wind Farm near Walcha. The Oven Mountain site is situated approximately 60 kilometers southeast of Armidale and 75 kilometers northwest of Kempsey. The area features steep, forested terrain along the Great Dividing Range and serves as the traditional country of the Thunggutti Indigenous people. The design relied on moving water between two dams via a turbine, storing energy generated during the day for release during peak nighttime usage. Although listed for consideration as a state significant development, the project remained in the assessment phase with NSW Planning authorities when the developer pulled out. Local political leaders reacted with surprise to the announcement. Sam Coupland, the Mayor of Armidale Shire, said the council learned of the cancellation only that morning. He described his reaction as shock and questioned whether state and federal planning regulations had become excessively burdensome. Coupland argued that numerous environmental requirements were rendering vital infrastructure projects unviable. He noted that the council had spent several years collaborating with Alinta Energy to plan supporting roadworks, specifically highlighting the Kempsey-to-Armidale Road restoration as the largest engineering project ever undertaken by a local council in New South Wales. Michael Kemp, the state member for the coastal electorate of Oxley, characterized the decision as a poor outcome for the mid-north coast community. He emphasized that the project would have generated significant trade jobs during construction and provided ongoing employment thereafter. Arthur Bain, the deputy mayor of Kempsey and chief executive of the Thunggutti Local Aboriginal Land Council, expressed mixed feelings regarding the loss. While acknowledging that the site’s steep gorge geography and natural waterfalls made it ideal for pumped hydro, Bain noted that the location’s isolation ultimately undermined its economic viability. The cancellation occurs against a backdrop of severe cost escalations in Australia’s largest renewable energy initiative, known as Snowy 2.0. An official report confirms that the Snowy 2.0 hydro scheme in New South Wales is now expected to cost up to A$25 billion, a figure exceeding twelve times the original estimate. The project, intended to function as a giant battery by pumping water between dams in the Snowy Mountains, will not be completed until late 2029. This timeline represents an eight-year delay from the initial projection announced by Prime Minister Malcolm Turnbull in 2017, when the anticipated price tag was merely $2 billion without a supporting business case. Three years prior to the current report, the Snowy 2.0 price tag had already been revised upward from $6 billion to $12 billion. However, the latest findings indicate that even the $12 billion estimate was based on incomplete construction designs. Upon completion, the facility will generate up to 2,200 megawatts of power, sufficient to supply three million homes for a week. The federal government has pledged to finish the project while criticizing the previous administration for lacking due diligence before construction began. In response, the opposition argues that the current government bears responsibility for the cost blowout given its duration in power. They also pointed to a 2023 funding change that shifted more cost risk to taxpayers. Critics argue that the core issue lies in approving projects before fully understanding risks and true costs. Australia has a documented record under both major political parties of failing to deliver megaprojects on time and within budget. A Deloitte report earlier this year found that thirteen publicly funded road, rail, and energy projects had exceeded their initial estimates by A$130 billion combined. Despite the strategic necessity of Snowy 2.0 to fill gaps in electricity generation and storage as coal plants retire, questions remain regarding the total financial burden on taxpayers versus contractors. Proponents of the Snowy 2.0 project highlight its long-term value compared to alternative storage methods. With the project approximately 80 percent complete, supporters argue that building grid-scale batteries with equivalent energy storage capacity would cost three times more than the final $22 billion estimate. Furthermore, while lithium-ion batteries typically last around 20 years, the Snowy 2.0 infrastructure is designed to operate for 150 years. Renewables currently provide about 50 percent of power in the National Electricity Market, with a government target of reaching 82 percent by 2030. As coal plants age and prepare for closure within the next decade, long-duration storage solutions like pumped hydro are viewed as essential for managing overnight demand when solar output is minimal. The debate extends to other major infrastructure ventures, including the national high-speed rail project connecting Newcastle to Sydney, which is expected to cost at least $93 billion if extended to Western Sydney’s international airport. A final decision on proceeding with that construction is slated for 2028. Meanwhile, the federal government has allocated nearly $660 million over the next two years to develop the investment case for the rail line. Observers suggest that Australia requires a more robust system to independently validate cost estimates for such massive undertakings to prevent future financial overruns.

Alinta Energy has cancelled plans for a $1.8 billion, 900-megawatt pumped hydro project in northern New South Wales, citing economic and timing challenges related to a critical transmission line. The Oven Mountain scheme, located near Carrai, was part of the Armidale Renewable Energy Zone and had undergone years of technical studies and stakeholder engagement before being deemed unviable. This cancellation marks the second major renewable energy project to be abandoned in the region this month, following the scrapping of Origin Energy’s Skye Ridge Wind Farm. Local officials expressed disappointment, with Armidale Shire Mayor Sam Coupland stating that excessive environmental regulations and planning hurdles were making such infrastructure projects financially unfeasible. The project was previously considered critical to state energy infrastructure, and its withdrawal leaves local councils having invested significant resources into supporting roadworks.

The Snowy 2.0 hydroelectric expansion project in New South Wales is now estimated to cost up to A$25 billion, a figure exceeding twelve times the original A$2 billion projection made in 2017. The completion date has also slipped to late 2029, eight years later than initially planned. While the current federal government pledges to complete the project, citing potential gaps in electricity supply if it were cancelled, the opposition holds the incumbent administration accountable for the cost overruns and recent changes to funding structures. Experts argue that the issue reflects a systemic failure in Australian governance regarding the approval of large-scale infrastructure projects without adequate risk assessment. Similar cost escalations have been observed in other major initiatives, including the High Speed Rail network and Melbourne’s Suburban Rail Loop.
