A $600 million gas-fired power plant in the NSW Hunter Valley has been given the final environmental tick of approval.
Federal environment Minister Sussan Ley said the project at Kurri Kurri was approved after rigorous assessment and on condition the government-owned Snowy Hydro Limited meets the conditions established by the NSW government when it approved the project in December.
The Hunter Power Project, due to be built by next year, would ensure ongoing reliable and affordable power for the people of NSW when the Liddell coal-fired power station shuts, Ms Ley said on Monday.
The the 660 MW plant will create up to 600 direct jobs at the peak of construction and 1200 indirect jobs across the state, she said.
"This thorough bilateral assessment with NSW has paved the way for the development and operation of this new critical infrastructure in a way that sensitively manages, protects and rehabilitates the environment," Ms Ley said in a statement.
Energy Minister Angus Taylor will visit Kurri Kurri to announce the approval of the plant on Monday.
The project was critical to keep the lights on and power prices low after the closure of the Liddell power station in 2023, he said.
"The project is good for jobs, it's good for business and importantly it's good for securing affordable, reliable power. "
The project was also vital to keep important businesses such as the Tomago Aluminium Smelter operating, he said.
Last week Labor agreed to support the project as long as it runs entirely on green hydrogen by 2030.
The policy change - which Labor defends as helping ensure jobs, and power supply- comes as the opposition attempts to defend its seats of Paterson, where the plant is located, and Hunter, where Joel Fitzgibbon is retiring.
However, community groups in the Hunter are vehemently opposed.
Gas Free Hunter Alliance co-ordinator Fiona Lee said the project would be "bad for the Hunter, and bad for Australia".
"Sussan Ley should be protecting the environment, not rubber stamping dirty, outdated fossil fuel projects which will worsen the impacts of climate change and pollute the local environment," Ms Lee said.
She accused Mr Taylor of lacking commitment to supporting regional communities to transition away from fossil fuels, or to taking real action on climate change.
"The Hunter region needs secure, future-focused jobs.
"Investing $610 million or more of public funds into an unnecessary and outdated gas plant will create just 10 long-term jobs."
More than 55,000 people have signed petitions opposing the power plant.
Of the 261 submissions on the proposed power plant, only two supported it, she said.
