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 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 and .

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.
