The $2 billion expansion of the Snowy Mountains hydro scheme, dubbed "Snowy Hyrdo 2.0", is set to be fast-tracked - with Prime Minister Malcolm Turnbull announcing today $8 million in funding towards a $29 million feasibility study on the project.
The upgrade aims to increase the 4,000 megawatt output by 50 per cent - a plan that will power up to 500,000 homes, and create 5,000 new jobs.
At the announcement Turnbull called the project, which will begin construction next year, "the biggest pump hydro scheme in the southern hemisphere."
Turnbull says the scheme will lead to lower electricity costs.
"We know there are at least a million households, probably a lot more, that are paying more for electricity than they need to because they are on the wrong plan," Turnbull said.
"So we are taking action right now to ensure Australians right now are not paying more for their electricity than they need."
Bill Shorten said of the PM's helicopter arrival at the site to make the announcement, "a joyride in a helicopter doesn't help families with their energy bills."
First announced during the 2017 Federal Budget, Treasurer Scott Morrison called the Snowy Mountains Scheme "the benchmark for nation building infrastructure."
At the time, Morrisson said the Commonwealth "is open" to acquiring a larger share or outright ownership of Snowy Hydro from the NSW and Victorian State Governments, "subject to some sensible conditions".
"First, all funds received by the States would need to be reinvested in priority infrastructure projects.
"Second, Snowy Hydro's obligations under its water licence would be reaffirmed and we would commit to work together to expedite and streamline environmental and planning processes associated with Snowy 2.0, without compromising any standards or controls.
Third, Snowy Hydro would have to remain in public hands."
The Federal Government has announced a $2 billion expansion of the Snowy Mountains hydro scheme, increasing the 4,000 megawatt output by 50 per cent - a plan that will power up to 500,000 homes.
The decision has been met with much impressed nodding from fellow politicians, and now here's what experts have to say about it.
