Hundreds of job seekers and high school students will be offered training to work on the Snowy 2.0 project.
The training will be offered under a partnership between TAFE NSW, the NSW government and the project's contractor Future Generation Joint Venture.
The Snowy 2.0 renewable energy project, located within Kosciuszko National Park, involves the construction of a 240-metre long pumped-hydro power station about 800 metres underground.
It is expected to generate about 2000 megawatts of electricity.
The federal government has said Snowy 2.0 will create 2000 jobs during construction and generate billions of dollars of investment in regional NSW.
The project needs skilled workers "ready to roll up their sleeves and get involved", NSW Premier Dominic Perrottet said in a statement on Saturday.
"I encourage young people across the state's south who are looking for an exciting opportunity to consider a future working on this project."
Deputy Premier Paul Toole said young people would be given practical skills and job-specific training to get jobs in the industry.
"Snowy 2.0 is a nation-building multi-generational project, and it's fitting that TAFE NSW plays a pivotal role in training the thousands of people who will make it a reality," he said.
Hundreds will be given specific training in manufacturing and civil construction, and high school students who enrol can split their time between school and working on site, Skills and Training Minister Alister Henskens said.
He said seven school-based apprentices from Monaro High School were already signed up and studying to become certified in process manufacturing.
Mr Henskens said it was a big win for the community because it means local youths receive training close to home.
Some 170 Snowy 2.0 workers have already been trained through TAFE NSW, Mr Henskens said.
TAFE NSW will also expand its programs in the Monaro region to include a certificate three in civil construction and several Aboriginal pre-vocational programs.
