Momentum around Snowy 2.0 keeps gathering speed with the Morrison Government approving the revitalised pumped hydro scheme on Tuesday (26 February) as part of its renewable energy plans for Australia’s future energy mix.

“The Government is pleased to announce shareholder approval has been given for Snowy Hydro Limited to proceed with Snowy 2.0,” Prime Minister, Scott Morrison said.

The next step in the historic project was announced at the Tumut 3 Powerstation, a location that demonstrates the potential the government sees.

“I stood in this very spot [as a child] with my grandfather [Sir William Hudson], who had recently retired as chief engineer and commissioner of the Snowy through the construction phase,” said Energy Minister, Angus Taylor.

“It was only a year or two after this power station [Tumut 3] where we stand had been opened.

“He explained to my family the potential and the impact of pumped hydro, he also explained that there was a great unrealised opportunity for the Snowy Scheme and that was to build a tunnel from Tantangara to Talbingo and use it for pumped hydro.”

Initiated by former Prime Minister Malcolm Turnbull, its hoped Snowy 2.0 will reduce volatility within the changing electricity market and address electricity price concerns.

“Following Snowy Hydro Board’s final investment decision on December 12, the Government has reviewed the project’s business case and is satisfied that the project stacks up and will benefit energy consumers and the Snowy Mountains region,” Mr Morrison said.

The Government has committed up to $1.38 billion in an equity investment for Snowy 2.0, with the remainder of the project to be financed by Snowy Hydro Limited.

“Almost 70 years after the first sod was turned on the mighty Snowy Scheme, we will do it all again,” Snowy Hydro CEO Paul Broad said.

“This significant expansion of the Snowy Scheme will provide the storage and on-demand generation needed to balance the growth of wind and solar power and the retirement of Australia’s ageing fleet of thermal power stations.

“Snowy 2.0 is not only a sound business investment for Snowy Hydro with over 8 per cent return on investment. It also represents the most cost-effective way to ensure a reliable, clean power system for the future.

“When it is completed, Snowy 2.0 will be able to deliver 2000MW of on-demand generation, up to 175 hours of storage, and deliver more competition that will keep downward pressure on prices.

“Snowy Hydro has a strong track record when it comes to pumped-hydro. For decades we’ve been successfully operating our pumping capability at Tumut 3 and that has been invaluable, especially in years of drought,” Mr Broad said.

The Prime Minister said Snowy 2.0 will create up to 2,400 jobs in construction and support up to 5,000 direct and indirect jobs across the Snowy Mountains, as well as provide opportunities for local businesses, improvements in local infrastructure and increased economic activity.

“Planning for the Snowy 2.0 project is well advanced. The Government’s decision green lights the project to progress to the early works stage,” Mr Morrison said.

From the other side of politics, Labor’s Dr Mike Kelly, Member for Eden Monaro says, “While I welcome the announcement that Snowy 2.0 will proceed, this project only makes sense in the renewable energy future that the Liberal and National party vehemently opposes.”

“Only Labor has a clear, consistent and modernising vision for Australia’s energy future; with cleaner renewable energy, more storage, and a modern transmission network.”

Earlier this month, the NSW Government gave planning permission for Snowy 2.0 exploratory works to start in Lobs Hole Ravine region between Tantangara and Talbingo Dams.

Hydropower will be generated by falling water spinning Snowy 2.0’s giant turbines, which can also pump water in the opposite direction. This closed system allows water to be used more than once between the upper dam (Tantangara) and lower dam (Talbingo).

A spokesperson for the National Parks Association (NPA) of NSW has labelled the environmental controls around the project as unsatisfactory.

“While a nation-building project, the Snowy Mountains Hydro Scheme caused enormous environmental damage across 380 sites, 36 requiring major earthworks and revegetation,” the NPA spokesperson says.

While the NPA supports a shift to renewable energy to decarbonise the electricity sector and supports pumped hydro as a component of this shift, it remains opposed to Snowy 2.0 despite the government’s assurances.

Snowy 2.0 is expected to take five years to complete.

There isn’t much water in the two dams and with experts saying climate change will make things worse, where is the water going to come from?

Until we get nuclear we should stick to coal.

Pumped Hydro is about grid scale storage of electricity but it is only about 40% efficient. For every 100kWh that is stored there only 40kWh is recovered due to frictions within the system. It is expensive but at least it is MUCH CHEAPER than using batteries.

When will Australia face reality about energy production and go nuclear. Nuclear is the safest form of energy. Call Bill Gates, he has put hundreds of million dollars into clean safe Gen 3 and Gen 4 nuclear power.
