Construction of the Hunter Power Project at Kurri has created 600 direct jobs and provided skill development opportunities in high-demand trades.
The number of apprentices on site are also rising, with Snowy Hydro working with principal contractor UGL to provide an additional 12 apprenticeship positions in June.
It included three female and two First Nations apprentices.
The positions include a boilermaker, nine electricians, and two mechanical fitters.
Construction of Australia's newest gas peaker is in the final stages. It is due to open in December as part of the federal government's Future Gas Strategy.
Snowy Hydro chief executive Dennis Barnes said the jobs boost would continue long after construction of the $950 million project was completed.
"We are proud of our contribution to the construction, engineering, and infrastructure sector here in the Hunter, especially given the current tradespeople shortages in Australia," he said.
"This project will have a lasting impact on the size and proficiency of the local workforce.".
Electrical apprentice Daniel Battle said he became interested in the electrical trade after working as a trades assistant on the project.
"This apprenticeship is giving me the necessary skills, knowledge, and experience while working to a high standard within the industry to become an electrician," he said.
Apprentice boilermaker Jackson Scott said he was passionate about fabrication and welding.
"I was very lucky to be offered an apprenticeship shortly after starting at the Hunter Power Project," he said.
"HPP is preparing me to have a successful career contributing to important infrastructure in our country, and I'm extremely grateful."
Electrical apprentice Camilla Lindeberg said she worked as a cleaner for seven months before applying for an apprenticeship.
"I never thought of being an electrical apprentice until the opportunity presented itself, and I'm excited for what the future holds," she said.
"The challenge of learning something new and directly contributing to building Hunter Power Project gives me a great sense of achievement and sets me up for a whole new career with endless opportunities," Ms Lindeberg said.
Snowy Hydro is also looking to the future workforce through its community support programme.
In 2024, Snowy Hydro extended its Local School STEM Fund to the Cessnock local government area.
More than $26,000 was awarded to schools in the area to foster learning opportunities and career pathways for local young people with a focus on STEM.
