Tallawarra gas-fired power station expansion passes regulatory milestone

A proposed expansion of EnergyAustralia’s gas-fired power station at Tallawarra in New South Wales has passed a significant regulatory milestone with a change accepted to the design of the expansion.

Tallawarra power station is located near Shellharbour Airport and during the early consultation phase of the project, concerns were raised by the airport users that the plume from the proposed open cycle gas turbine could cause potential impacts on aviation activities.

EnergyAustralia Tallawarra B project director Julian Turecek said, “We worked with Shellharbour Council, local airport users and other stakeholders to significantly redesign our proposal to lower the plume height”.

The NSW Department of Planning, Industry and Environment and the Civil Aviation Safety Authority (CASA) have now determined that aviation risks have been managed to an acceptable level.

The project is on track to boost the state’s power supplies for the summer of 2022-23, ahead of the scheduled retirement of the Liddell power station.

“Our stakeholders appreciated the importance of this project for New South Wales households and businesses, and they were generous with their input,” Mr Turecek said.

“That’s meant we’ve been able to improve the engineering design so that we have an even better project than what was originally proposed.

“With an innovative engineering solution that lowers the plume from the open cycle gas turbine, we have demonstrated that aviation and a new gas plant can safely co-exist.”

The Tallawarra plant expansion is estimated to deliver a $300 million boost to the Illawarra economy and create hundreds of jobs during peak construction. Once developed, the 300 megawatt facility could start within 25 minutes and power around 60,000 New South Wales homes.

With regulatory approval in place, EnergyAustralia will now focus on securing a contract for supply and construction and finalise the business case, with the aim of making a final investment decision later this year.

The Tallawarra development follows the announcement last week that EnergyAustralia had agreed to underpin development of the 250 megawatt Kidston pumped-hydro storage facility, located in Queensland.

“These projects are examples of the modern energy system taking shape in Australia. These are challenging times, but we won’t be slowing down. Our customers and communities are depending on us,” Mr Turecek said.
