Maintenance outage underway at Bayswater power station

A $24 million maintenance outage is currently underway at AGL Macquarie’s Bayswater power station, near Muswellbrook.

Work started on Bayswater Unit 3 on March 31, with the outage expected to be completed by late May.

AGL Macquarie general manager Kate Coates said the work will prepare the power station for efficient and reliable operation over the years ahead.

“The outage has started well and we are confident of completing the work on time,” Ms Coates said.

“In particular, with winter approaching, we are focused on preparing our power stations for the increase in energy demand colder weather can bring.

“Power stations like Bayswater are built with four separate generating units.

“Each unit runs autonomously and can be taken offline for maintenance without any impact on the operation or output of the remainder of the power station.

“To ensure the station operates efficiently and to prevent unexpected breakdown, each unit needs scheduled routine maintenance.”

With traditionally lower energy demand levels during current autumn months, the outage will not affect customers’ energy supply.

“Hundreds of contractors have arrived on site, and are working with the AGL Macquarie team for the seven-week outage,” Ms Coates said.

“It is a busy time, and our employees and contractors are working hard to ensure reliable energy for our community and customers.

“During the seven weeks we will complete over 75,000 hours of work.

“With most contractors staying in the region, the outage will also be a significant economic boost for the Upper Hunter.”

Contractors working on the outage include Toshiba, TW Power Services, ALS and GE.

The scope of work planned for the outage includes extensive inspection surveys and repairs on secondary super heater panels, secondary air heaters and gas ducts.

Several special maintenance projects will also be completed during the seven weeks.

A new generator circuit breaker unit and an upgraded generator protection system will be installed, both supplied by GE.

A replacement high pressure heater is also being lifted into position.

The 48-tonne vessel was manufactured in New Zealand over the past six months, and arrived recently in Port Kembla, before being transported to Bayswater power station.
