How do critics view the feasibility and economic viability of Snowy 2.0?
-Critics argue that Snowy 2.0's economic and technical feasibility is questionable due to its high costs, long delays, and the availability of alternative energy storage solutions like batteries that could be cheaper and quicker to deploy.
What are the benefits of Snowy 2.0, despite the challenges and criticisms?
-Despite the criticisms, Snowy 2.0 is seen as a crucial part of Australia's energy transition, providing long-duration storage for renewable energy and ensuring energy security by contributing to the stability of the national grid.
Outlines
π Snowy 2.0: Ambitions and Challenges
Snowy 2.0, a pumped hydro scheme aimed at fostering a low-carbon future, is portrayed as a critical engineering and environmental endeavor with the potential to power up to 3 million homes for a week. Despite its promise as a valuable asset for the energy transition, the project faces criticism for long delays and escalating costs. Early enthusiasm for its nation-building potential is contrasted with significant setbacks, including a stuck tunnel boring machine (TBM) named Florence, indicative of deeper issues such as cost underestimations and ground condition misjudgments. The narrative underscores the challenges of balancing technical ambition with practical realities, highlighting both the optimism surrounding the project's impact on energy transition and the critiques of its execution.
π Technical Setbacks and Political Ambitions
The journey of Snowy 2.0 is marked by significant technical and administrative hurdles, starting from its conceptualization during an energy crisis, through its political endorsement by Prime Ministers Malcolm Turnbull and Scott Morrison. The project, initially sketched on a beer coaster, symbolizes a high-stakes response to Australia's renewable energy storage needs, yet it quickly encounters geological challenges, cost blowouts, and delays. This narrative strand explores the dichotomy between the political will to realize a vision of nation-building through renewable energy storage and the complex reality of engineering challenges, environmental concerns, and community opposition.
π Environmental Impact and Community Concerns
The development of Snowy 2.0 is faced with environmental and social challenges, including concerns over its impact on national parklands and community apprehension regarding new transmission lines. Despite its potential to contribute significantly to Australia's energy transition, the project's execution raises questions about the balance between technological progress and environmental stewardship. The discussion extends to the implications of large-scale infrastructure projects on local communities and ecosystems, emphasizing the importance of careful planning and stakeholder engagement in achieving sustainable development goals.
πΌ Corporate Governance and Public Trust
Snowy 2.0's progression is complicated by issues of transparency and public communication, particularly concerning the challenges faced by the TBM Florence. The narrative delves into the management decisions and the ensuing public scrutiny over the project's cost overruns and operational setbacks. This section highlights the importance of trust and accountability in public infrastructure projects, questioning the balance between corporate optimism and the reality of project execution. It examines the role of corporate governance in fostering public trust and the critical need for honest, transparent communication with stakeholders.
π§ Safety Concerns and Contractor Performance
The construction phase of Snowy 2.0 unveils significant safety concerns and criticisms of the main construction contractor's performance history. The project's challenges are compounded by incidents leading to worker injuries and environmental hazards, casting a shadow over the contractor's safety record and operational decisions. This part underscores the critical importance of safety in large-scale engineering projects and the consequences of compromising on contractor selection and risk management practices, reflecting on past incidents to stress the necessity of prioritizing worker safety and environmental protection.
π Reevaluating Renewable Energy Solutions
As Snowy 2.0 continues to face operational, environmental, and financial hurdles, the discussion shifts towards alternative renewable energy solutions and the broader implications for Australia's energy policy.

Highlights
snowy 2.0 was sold as nation building, for a low carbon, future it's a revolution it's exciting, from a technical and Engineering point, of view but it's absolutely critical to, save the planet from being, fried
a mega project that could power up, to 3 million, homes for an entire week we are building, something which is an incredibly, valuable asset to the energy transition
but this pumped Hydro scheme has been, afflicted by long delays and massive, cost, blowouts
I knew it was just going to be, an absolute dog of a project that making, outlandish claims about when the sche, was going to be finished and they still, are
they got, the cost wrong the ground conditions the, time the schedule and I think the way, they leveled with the public they've got, that wrong, too
deep in the snowy mountains a giant, tunnel boring machine is stuck the, perfect illustration of how this, socalled nation building project has, gone so horribly wrong
on this episode, of Four Corners we go beyond the, corporate spin to reveal the inside, story of snowy 2.0 and how repeated, warnings of problems that lay ahead were, ignored
Dennis Barnes became snowy, hyro chief executive in February, inheriting a project plagued by problems
snowy 2.0 is being built in, rugged country deep in the Kiosco, National, Park
it will will now cost $12 billion, six times the initial estimate for this, snowy has copped sustained criticism
imagine more than 20 km of tunnels this, size full of, water so lots of people have said really, harsh things about snowy 2.0 that'll, never be completed what do you say to, them
we're about to go on, board a massive tunnel boring machine, called Florence it's at the very heart, of snowy's, problems
Florence has barely moved in 19, months at the entrance to the tunnel, where the machine is stuck sits a small, statue of St Barbara the patron saint of, tunneling she's charged with protecting, workers and watching over, projects
snowy will be hoping for her, good good, grace we encountered soft ground before, we were expecting, to that soft ground stopped Florence, suppos to step hazards and created a, world of pain for Dennis, Barnes
I expect in weeks not, months as soon as the slurry plant is, operating we'll push forward I was, wrong there's you know mistakes that we, all make and I was wrong to you know, perhaps somewhat naive and optimistic uh, and you know I'm learning as I go as you, would, expect
