The Hunter Transmission Project has been approved, marking what’s being described as a critical milestone for New South Wales’ energy transition.
The project will deliver a new 110-kilometre, 500 kilovolt overhead transmission line running from Bayswater, near Muswellbrook, to Olney, near Eraring, connecting into the state’s wider electricity network. About 90 per cent of the route will be located on mining, energy and government-owned land, a change made in response to community feedback that has reduced the number of directly affected private properties from around 70 to fewer than 20.
The approved pathway has also been adjusted to avoid and minimise impacts on trees and vegetation, and now avoids nearly all known breeding ponds for the threatened Littlejohn’s Tree Frog. The approval carries strict conditions covering social impacts, biodiversity, Aboriginal cultural heritage and local business participation, along with ongoing community engagement requirements as the project moves into delivery.
EnergyCo says the project is expected to support around 830 construction jobs, including around 1,500 direct and indirect jobs across the state. Subject to Federal Government approval, construction is expected to begin in late 2026 and be completed by late 2029.
Minister for Climate Change and Energy Penny Sharpe said the project is one of the most important in the state’s history.
“The Hunter Transmission Project is one of the most important energy projects in NSW because it will help keep the lights on as ageing coal-fired power stations retire,” she said.
“This project is the missing link between the renewable energy being built in Central-West Orana and New England and the millions of homes, businesses, schools and hospitals that rely on affordable and reliable electricity every day.
“Planning approval means we can get on with building the infrastructure needed to secure NSW’s energy future, create jobs, attract investment and deliver cleaner, more affordable power for households and businesses.”
