Wind Power: Noise

Volume 503: debated on Thursday 14 January 2010

To ask the Secretary of State for Energy and Climate Change pursuant to the answer of 7 January 2010, Official Report, column 636W, on wind power: noise, for what reasons he endorses the current maximum permitted night-time noise limit from onshore wind turbines. (310705)

As stated in my answer of 7 January 2010, the 43 decibel night-time limit in the ETSU-R-97 guidance is derived from the 35 dB(A) sleep disturbance criteria referred to in Planning Policy Guidance 24 (Planning and Noise).

ETSU-R-97 describes a framework for the measurement of wind farm noise and gives indicative noise levels thought to offer a reasonable degree of protection to wind farm neighbours, without placing unreasonable restrictions on wind farm development or adding unduly to the costs and administrative burdens on wind farm developers or local authorities. The suggested noise limits in ETSU and their reasonableness have been evaluated with regard to regulating the development of wind energy in the public interest. We have no robust new evidence to suggest that the current guidance is not achieving its aim.
