The overhaul of Wivenhoe power station’s second unit has finished and is set to produce electricity for the national grid again.
The refurbishment took 85 days and cost owner CS Energy $13.5 million. It has a design life of 100 years.
Chief executive officer Martin Moore said the overhaul would ensure the power station operated safely, reliably and efficiently into the future.
CS Energy’s pumped storage hydroelectric Wivenhoe Power Station’s overhaul has finished.
“Wivenhoe Power Station is a peaking power station that has provided quick start capacity to the national electricity grid since 1984,” Mr Moore said.
“The power station works like a giant rechargeable battery by cycling water between an upper and lower reservoir,” Mr Moore said.
“Wivenhoe’s upper reservoir, Splityard Creek Dam, has a capacity of 23,300 megalitres, which is enough to run the power station for up to 10 hours at full load.”
Wivenhoe power station is the only pumped storage hydroelectric plant in Queensland and consists of two 250 megawatt units that are the largest hydro machines in Australia, which each have almost 1500 tonnes spinning when in operation.
