Greens NSW Lead Candidate David Shoebridge made the announcement alongside Riverina Green’s candidate Ray Goodlass, and said the plan will be far reaching.

“PowerNSW is the Green’s vision for public-owned, 100 per cent renewable energy in NSW,” he said.

“It will be a game changer for the state and households, cutting costs, tackling climate change, and delivering jobs and real economic benefits to the region.”

Mr Shoebridge said PowerNSW will have energy hubs in four locations across NSW, including the Riverina and Murray region, Central West, Northern Tablelands and Broken Hill. 

As well as fighting climate change, Mr Shoebridge said the initiative will save the public hundreds of dollars.

“It will be a retailer, a distributor and a generator, and we know by having a publicly owned retailer and taking the sale of electricity out of the hands of corporate bodies, we can save households between 250 and 380 dollars a year on their power bills,” he said. 

Construction of relevant infrastructure is estimated to take 2-5 years, costing $5 billion.

"$5 billion to save the nation from the on-going impact of climate change is a worthwhile investment," Mr Shoebridge said. 

The Greens' lead candidate said the plan will provide up to 4,000 jobs over the next decade, and is hopeful regional land-owners will get on board.

"A key part of delivering renewable energy through PowerNSW is building the large scale solar and wind generators in regional NSW, and we know that this part of regional NSW, from the river all the way through to the hay plains, has extraordinary renewable energy potential, especially in solar," he said.

"We’re expecting a significant buy in from land-owners that will get an ongoing guaranteed return for their land when renewable energy projects are put in place.

"Solar and wind farms have a very low impact on land-owners and allow the land to continue to be used for productive agricultural needs."

Mr Shoebridge said the plan will lead to NSW being completely renewable if successful. 

"It will build one gigawatt of renewable energy a year on a reverse auction basis, and when done for a decade, that will make NSW 100 per cent renewable," he said.

Riverina's Greens candidate Ray Goodlass said the plan needs to be a priority.

"We need to prioritise ecological sustainability to ensure that the planet continues to provide a welcoming home for all life," he said.

"We can really bring down energy prices by returning gas and electricity to the public sector."
