Overhaul Keeps Wivenhoe Power Station in Top Shape
Media Release Tuesday, 17 November 2015 Overhaul keeps Wivenhoe Power Station in top shape A $5.2 million overhaul at CS Energy’s hydrolectric Wivenhoe Power Station near Brisbane wrapped up recently, ensuring the power station continues to generate electricity safely and reliably for Queenslanders. CS Energy Chief Executive Officer Martin Moore said the Wivenhoe works were one of four overhauls planned for CS Energy’s power stations this financial year, adding up to a $71.4 million investment in these important assets. Mr Moore said each overhaul provided an economic boost to accommodation and other businesses in communities surrounding CS Energy’s power stations. “CS Energy’s site workforces increase significantly during an overhaul as short-term contractors are required to help carry out the maintenance and upgrades of the power station equipment,” Mr Moore said. “Wivenhoe Power Station’s workforce grew more than five-fold during this overhaul – up from a permanent workforce of 14 people to a peak of more than 90 people when you include the 80 contractors on site.” Mitsubishi Hitachi Power Systems was the major contractor for the two-month overhaul, with additional contractors carrying out specialised work including ABB, Schneider, ViPac, Berg Engineering and Crown Engineering. Mr Moore said Wivenhoe Power Station has a 30 year history of providing quick-start capacity to the national electricity grid. “Wivenhoe Power Station works like a giant rechargeable battery, drawing power from the grid to pump water from Wivenhoe Dam up to Splityard Creek Dam,” Mr Moore said. “The water is then released from Splityard Creek Dam down through tunnels to the power station’s turbines, driving the generators to produce electricity.” Wivenhoe Power Station is the only pumped storage hydroelectric plant in Queensland. -

Wivenhoe Power Station
Wivenhoe Power Station Location Wivenhoe Pocket via Fernvale, in South East Queensland Capacity 570 MW for 10 hours Fuel Pumped storage hydroelectric Employees 13 employees CS Energy is a Queensland government owned corporation and a major wholesale provider of electricity in Australia. We employ almost 500 people and have a trading portfolio of 4,105 megawatts in the National Electricity Market (NEM). CS Energy operates the 1,510 megawatt Callide Power Station near Biloela in Central Queensland, the 750 megawatt coal-fired Kogan Creek Power Station, near Chinchilla in South West Queensland, and the 570 megawatt pumped storage hydroelectric Wivenhoe Power Station, near Esk in South East Queensland. The Kogan Creek Mine also forms part of CS Energy’s portfolio of assets. Wivenhoe Power Station Wivenhoe Power Station is the only pumped storage hydroelectric plant in Queensland. This strategic asset in CS Energy’s portfolio provides fast ramping capability. Wivenhoe’s two 285 MW units are the largest hydromachines in Australia, weighing 1,500 tonnes each. Electricity is generated, absorbed and stored at Wivenhoe Power Station by recycling water between a lower reservoir (Wivenhoe Dam) and upper reservoir (Splityard Creek Dam). Using electricity from the grid, Wivenhoe Power Station pumps water from Wivenhoe Dam up into Splityard Creek Dam. The water is then released from Splityard Creek Dam through tunnels back to the power station to drive the Callide Power Station turbines and generators to produce electricity. In this way, Wivenhoe Power near Biloela in Central Queensland Station works like a giant rechargeable battery. Kogan Creek Power Station Commissioned in 1984, the power station has an expected life of up to 100 years. -
