Germany-headed energy utility major RWE AG has revealed that it has invested some £200 000 (≈ EUR 233 000) on new noise abatement technology for its Markinch Power Station in Fife, Scotland. The 55 MW biomass-fired combined heat and power (CHP) plant has the ability to generate power for 100 000 homes and has been operational since 2015, most recently investing in a state-of-the-art Energy Centre that provides heat to the Glenrothes Energy Network.
In 2019, RWE conducted a noise assessment and identified a low-frequency tonal noise associated with the steam turbine generator. Although the noise is within all operational limits, RWE has been working with the Scottish Environment Protection Agency (SEPA) to find a solution to minimize any audible background noise.
RWE identified a material that can act as an acoustic jacket around the generator and the installation was fitted during the first half of 2021. The technology is fitted externally therefore the station’s operations were not impacted.
Following a series of noise performance tests on and offsite by an external specialist, results confirm that the insulation has significantly reduced the low-frequency tonal noise.
RWE is committed to improving the efficiency of the plant, with both technical and physical investments. It is also important that we look for ways to minimize the impact our operations have on the local community. Many of our staff live locally and RWE is proud to be a part of the local community We will continue to work with local stakeholders and look for constant improvements, commented Kathrin Schmelter, Plant Manager, Markinch Power Station.
