Stanwell has reaffirmed its commitment to delivering affordable, reliable and sustainable energy for all Queenslanders.

In FY25, the Queensland Government introduced the Electricity Maintenance Guarantee (EMG) to provide safe, secure and reliable electricity supply, through the prioritisation of financial and non-financial performance of Stanwell’s portfolio of thermal generation assets.

In line with the EMG’s requirements, Stanwell continues to prioritise the maintenance and performance of its thermal generation assets, successfully delivering all FY25 key performance indicator (KPI) targets across personal safety, process safety, operational performance and capital investment.*

Stanwell CEO Michael O’Rourke said Stanwell takes great pride in making sure its coal-fired power stations are well maintained so they operate safely and reliably – providing critical grid stability.

“Stanwell and Tarong power stations are two of the most reliable and efficient coal-fired power stations in the National Electricity Market (NEM),” Mr O’Rourke said.

“We provide more than a third of all Queensland’s power with a 12-month moving average reliability factor greater than 98 per cent. This is how Stanwell delivers safe, secure and reliable electricity supply to the market.

“This is further highlighted by Stanwell’s summer availability performance of 96 per cent (from the start of December to the end of March).

“Stanwell undertakes a rigorous year-round asset maintenance program, including major unit overhauls, under its long-term Asset Management Strategy to ensure generation assets continue to operate safely and reliably.

“In the past financial year alone, Stanwell invested approximately $200 million on three major overhauls at Stanwell and Tarong power stations.”

Mr O’Rourke welcomed the upfront approval of sustaining capital required to implement the five-year asset management plan, as part of the Electricity Maintenance Guarantee.

“Over the next five years, we’ll invest $908 million in sustaining capital across our assets and operations, the majority of which will be used to ensure our coal-fired power stations continue to remain safe, reliable and responsive to the evolving needs of the energy market,” he said.
