AGL appoints demolition contractor for Liddell Power Station


The closure of AGL’s Liddell Power Station in the Upper Hunter is a step closer to fruition.

Delta Group has been awarded the contract for its demolition as the site prepares for its transformation into a low carbon industrial energy hub.

After first announcing the retirement of Liddell in 2015, the full termination of the plant, located between Muswellbrook and Singleton, will now take place in April next year – with one of four units already retired in April 2022.

AGL chief operating officer Markus Brokhof said it would be the first of the company’s thermal generation sites to be converted into an integrated, low-carbon industrial energy hub.

“After more than 50 years of generating electricity for Australia, Liddell Power Station has reached the end of its operational life and will close in April 2023,” he stated.

“We’re very pleased to announce Delta Group has been awarded the contract for the demolition of the station.

“It’s a significant piece of work.

“Liddell Power Station has been an important part of the Upper Hunter community for a long time now and it’s also the home of many great memories for thousands of people who’ve worked there over the years.”

The demolition process is expected to begin in early 2024 and take approximately two years. 

Work will include removal of all main structures (boilers, chimneys, turbine houses, coal plant) and ancillary buildings, and leveling of the site using recovered crushed concrete.

More than 90% of the materials in the power station are expected to be recycled during demolition, including 70,000 tonnes of steel which is more than the total weight of steel works for the Sydney Harbour Bridge.

Critical infrastructure, such as transmission connections, will be retained to support the ongoing use of the site as an industrial energy hub, helping provide employment and essential economic activity for the region.

Planning approval has already been granted for a 500MW/2GWh grid-scale battery.

Delta Group executive general manager Jason Simcocks admitted they were looking forward to executing the “landmark” project.

“Our team’s approach during the planning phase has helped us to better understand AGL’s and its stakeholder needs, requirements and expectations in relation to the closure process,” he said.

“We’re fully-committed in assisting AGL achieve a low-risk, safe and environmentally-sound project leaving behind a positive legacy for the local and regional community.

“We’ll work with residents, industry, businesses and local governments to achieve this common goal.”
