Assets and Resource Use
Hydro Tasmania ensures sustainable hydropower production by careful engineering management of its portfolio of generation assets through maintaining, refurbishing and upgrading as required to balance production opportunities with risk management whilst ensuring public safety.
A comprehensive risk management program monitors the condition and performance of our assets and prioritises maintenance, refurbishment and upgrade projects to implement the program.
In 2007-08, Hydro Tasmania made significant improvements to lift asset management further towards a sustainable proactive approach and world-class practice. We developed a system to monitor condition and performance and assess risk for the entire generation portfolio. This in turn improved and clarified maintenance and operational requirements and more clearly defined the five-year capital works program. Importantly, the process also improves the alignment of asset management with NEM trading requirements. Identified ‘champions’ are responsible for implementing the plan in 2008-09 and coordinating works to achieve a balance between plant outage, energy supply and trading outcomes.
Hydro Tasmania invested $37.4 million in capital works for assets during 2007-08, with major work on Poatina Power Station and the Lemonthyme Power Station and its water conduit.
Two significant unplanned outages resulted from plant failures at Poatina and Bell Bay power stations. Our people responded rapidly to resolve the problems and showed an outstanding level of ingenuity, collaboration with our suppliers and teamwork across the business. The reviews of each event led to improvements in systems and processes.
The age of Bell Bay Power Station provides a challenge to managing the condition of the plant which is maintained under contract by Transfield Worley Parsons.
