The projects will be constructed in two of the state's Renewable Energy Zones.
The projects in Apsley (Central-West Orana REZ) and Muswellbrook (Hunter Central Coast REZ) involve building and operating 120-megawatt and 150-megawatt battery storage systems which will connect to the existing electricity network.
The new projects will create 132 jobs inject $280 million into NSW's economy, help maintain energy reliability and keep the lights on throughout the state.
The REZs across New South Wales are the power plants of the future. They will support new jobs and business opportunities during construction and operation in regional areas.
There are currently 27 large-scale renewable energy, transmission lines and storage projects under assessment in the NSW planning system. If approved, they would provide 9 gigawatts of renewable energy and 5.5 megawatts of firming storage.
The battery is expected to be operational towards the end of 2025 and has a lifespan of 20 years.
The Renewable Energy Roadmap will provide 12 gigawatts of renewable energy by 2030. The approval of the Apsley and Muswellbrook projects takes us closer to that target.
Quotes attributable to Minister for Energy, Penny Sharpe
"Giving these batteries the green light will play a critical role in securing reliable, renewable energy across NSW.
"The transformation of our energy system needs to occur as soon as possible.
"Batteries are not only critical to supporting our state's transition to net zero, they will assist us to get there sooner."
Quotes attributable to Minister for Planning and Public Spaces, Paul Scully
"This cutting-edge technology will capture, store and distribute energy to help secure supply for thousands of homes and put downward pressure on electricity prices.
"The batteries will be used during peak power consumption times and provide backup during outages or extreme weather events reducing the need for costly distribution upgrades or emergency generators."
