The stacks are expected to be brought down in April next year.

Works to demolish and remove other parts of the decommissioned power station will start this July.

“Liberty Industrial has been appointed to manage the demolition of Munmorah Power Station, which was decommissioned in 2014,”  Delta Electricity’s interim chief executive Ray Madden said.

“Liberty Industrial are expected to take possession of the site this month, with staged demolition works expected to start in July.”

The demolition is expected to be completed by September 2018. 

The site will be cleared to ground level, meaning that all structures on the site including the power station building, coal plant buildings, overland conveyors, above-ground pipelines and the two chimney stacks will be removed. 

“Munmorah Power Station was built in the 1960s and was closed after 45 years of operation in 2012,” Mr Madden said.

“Its ageing infrastructure and cost of operation meant that it was no longer economically viable to compete against newer and more efficient plants.” 

Liberty Industrial have developed a staged demolition plan that outlines the order in which the demolition will take place. 

“Demolition works are likely to commence with the turbine halls, coal conveyors and coal plant,” Mr Madden said.

“The felling of the chimney stacks is planned for approximately April 2017.”

He said Liberty Industrial had been appointed for their expertise with large industrial demolition projects and their “impeccable safety record”. 

Colongra gas-fired power station is located adjacent to the old coal-fired power station, and it will continue to operate.
