Stubbo Solar Project Achieves Full Commercial Operation in NSW
A big solar farm called Stubbo Solar in New South Wales, Australia, has officially started working at full power.
It's one of the largest solar farms ever built in Australia and cost a lot of money to build.
This solar farm can make enough clean electricity to power many homes.
It was built by a company called ACEN Australia, which is working with the government to bring more clean energy to the state.
The project also made sure all its solar panels can be reused or recycled when they are old, which is good for the environment.
It also helped local businesses and communities during its construction.
This is part of a bigger plan to use more renewable energy and stop relying on fossil fuels.
Stubbo Solar, a 520 MWdc (400 MWac) solar project in New South Wales, has reached full commercial operation.
The project represents an investment of approximately AUS $760 million and is one of Australia's largest solar installations.
It was developed ahead of the formal establishment of the Central-West Orana Renewable Energy Zone.
Stubbo Solar is the first large-scale solar project certified for full circularity, ensuring panel reuse or recycling.
The project invested nearly AUS $85 million into the NSW economy during construction, including support for local businesses and First Nations communities.
