The Ghost Pine Wind Energy Centre, located in Kneehill County, Alberta, includes 51 wind turbines and has the capacity to generate 82 MW of electricity. The wind project consists of 51 wind turbine generators, each at 262 m tall and with a capacity of 1.6 MW. HGC Engineering was retained by NextEra Energy Canada to complete sound level monitoring at several locations near the Ghost Pine Wind Energy Centre.
A Comprehensive Sound Level Survey of the facility was conducted to fulfill the requirements of a decision published by the Alberta Utilities Commission (AUC). The decision required a determination of the noise contribution of the wind facility at three nearby noise-sensitive receptors. The Comprehensive Sound Level Survey was conducted in accordance with the AUC’s Rule 012: Noise Control, which sets out requirements for noise control/assessment of energy facilities and provides specific guidance for the measurement of audible sound from wind turbine generators.
An automated sound level monitoring station was deployed at each of the three receptor locations to collect the data required by Rule 012. All instruments deployed by HGC Engineering were remotely accessible in order to periodically validate the collected data, monitor the operation of the equipment, and to reduce the number of site visits required.
