Wivenhoe Power Station Noise Control PROJECT: Wivenhoe Power Station INDUSTRY TYPE: Power Generation CLIENT: CS Energy LOCATION: Wivenhoe Initial project requirements: Wivenhoe Power Station, operated by CS Energy, is a hydropower generating system. Wivenhoe is approximately 50 km west of Brisbane and is the only pumped hydroelectric storage plant in Queensland. Not only is the power station the only pumped storage hydroelectric plant in Queensland, but it also has two of the largest hydro machines in Australia – 285 MW generators. The power station cycles water between Splityard Creek Dam and Wivenhoe Dam. The power station turbine room generates high noise levels, creating an uncomfortable working environment for the adjacent offices. Flexshield solution: Flexshield has an existing working relationship with CS Energy, having also worked with CS Energy at Kogan Creek Power Station. The Flexshield Group has a long experience working on Power Station noise control solutions across Australia - the full list is at the end of the case study. For our current project with CS Energy, our AcousTech senior acoustic project engineer visited the site to conduct an acoustic assessment and design the solution. The solution included treating the existing office with high-density V100 Sonic System modular acoustic panel facing the perforations into the room. We also replaced the current non-acoustic cold room doors with Flexshield high- performance Sonic Access Rw46 acoustic doors. Noise levels were further reduced by adding Calando Nude White panels to the ceiling. We sourced the Calando Panel from our Commercial Acoustics Company – Avenue Interior Systems. The solution Flexshield provided made a more comfortable working environment - allowing workers to communicate better and improve the number of sick days due to noise fatigue.

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.
