The cost of Snowy Hydro 2.0 has blown out to as much as $25bn, with a major reassessment finding the long-delayed renewable energy project will not be completed until the end of the decade.
asserted
project → blow → decade
First touted by the Turnbull government in 2017 with a price tag of $2bn, the cost of the project in the Kosciuszko national park has increased dramatically over time.
asserted
cost → tout → time
In 2023 it was revised to almost $13bn, with construction due to completed by the end of 2028.
asserted
construction → revise → 2028
But new projections by the Snowy Hydro company, released on Thursday night, shows it will now cost at least $22.2bn, with contingency for a further increase to $25bn.
asserted
it → release → 25bn
Work to build the new underground power station is under way, with about 5,000 people at work on the project.
But the project reset shows Snowy 2.0 won’t be completed and fully commissioned until 2029.
asserted
Snowy → build → 2029
The Albanese government plans to announce additional project oversight and financing structures for Snowy 2.0 in coming weeks.
asserted
government → plan → weeks
Another injection of taxpayer funds is expected, along with possible private financing components.
asserted
injection → expect → components
Beset by challenges – including major delays when a specialist boring machine became bogged and wedged in hard rock – the project’s timeline and extraordinary cost overruns have been blamed on its unique nature, significant risk and technical complexity.
asserted
timeline → Beset → nature
The boring machine, known as Florence, is still not yet at the halfway point of its 15km tunnel work.
asserted
machine → bore → work
Principal contractor, Future Generation Joint Venture (FGJV), also faced “cost estimation challenges”, according to the company.
uncertain
contractor → face → company
Since the project was signed off on in late 2018, more detailed technical analysis has been required, while FGJV has missed productivity targets and failed on cost and planning performance.
asserted
FGJV → sign → performance
Global price rises for construction equipment, services and staff have all exceeded early estimates.
asserted
rises → exceed → estimates
The project aims to link two existing Snowy reservoirs with tunnels up to 27km long.
asserted
project → aim → tunnels
Once completed, it will be able to generate 2,200 megawatts of power and provide 350,000 megawatt-hours of storage.
asserted
it → complete → storage
Despite the soaring cost and repeatedly delays, Snowy Hydro chief executive, Dennis Barnes, said the situation could have been worse.
uncertain
situation → soar → cost
“This project is incredibly complex, it is off the charts even for mega projects,” he said.
asserted
he → say → projects
“The original contract had so many flaws, and the project was stalled.
asserted
project → stall → flaws
The thing I’m pleased about is that if it wasn’t for the reset, if it wasn’t for the collaborative relationship we now have with the contractor, I think this would have been worse.
asserted
this → ’m → contractor
“The silver lining is the project is beginning to hit its straps.”
asserted
project → begin → straps
Asked if he was concerned community confidence in Snowy 2.0 was shot, Barnes said the project would provide half the storage capacity needed for renewables in Australia and would help lower electricity prices.
asserted
project → ask → prices
Snowy 2.0 is expected to be the largest source of stored dispatchable energy in the national electricity market, with its functions to include firming intermittent wind and solar generation and absorbing surplus renewable generation during periods of low demand.
asserted
Snowy → expect → demand
It will provide peak-load generation during periods of high demand and boost supply during prolonged periods of low wind and solar output.
asserted
It → provide → output
Critically, it is designed to reduce extreme wholesale price spikes by adding substantial supply when the market is stressed.
asserted
market → design → supply
“I’m confident that we can get the message out that the lowest cost system of the future is renewables backed by Snowy pumped hydro, batteries, and gas,” Barnes said.
asserted
Barnes → ’m → hydro
The energy minister, Chris Bowen, and the finance minister, Katy Gallagher blamed the former Coalition government for the poor design and cost projections, but insist Snowy 2.0 is necessary to strengthen Australia’s national energy grid.
asserted
Snowy → blame → grid
Labor looks set to attempt to place blame for the delays and overruns at the feet of the former energy minister and current opposition leader, Angus Taylor.
asserted
Labor → set → minister
“The government remains transparent about the pressures facing this project and securing the best possible outcome for taxpayers, energy consumers and the grid,” they said in a statement.
asserted
they → remain → statement
“Once complete, the pumped hydro expansion of the Snowy Scheme will provide more than half of the total energy storage the grid needs by 2050, strengthening energy security and putting downwards pressure on energy prices.”
asserted
grid → pump → prices
