Regulations) be used to inform the noise assessment. Section 7 of the EMPC Regulations states:
7. Fixed equipment
(1) A person must not operate fixed equipment on any premises –
(a) from 7.00 a.m. until 10.00 p.m., if the fixed equipment, when so operated, emits noise that is greater than 45dB(A); or
(b) from 10.00 p.m. until 7.00 a.m., if the fixed equipment, when so operated, emits noise that is greater than 40dB(A).
(2) A measurement of noise, emitted by fixed equipment on any premises, that is to be measured at residential premises –
(a) is to be taken one metre from the external wall, of the residential premises, that is closest to the fixed equipment emitting the noise; or
(b) if the distance between the external wall of the residential premises closest to the fixed equipment and the property boundary of the residential premises is less than one metre, is to be taken at that property boundary.
Council has confirmed to Neoen that the specified noise levels of 45 dB(A) (7 am to 10 pm) and 40 dB(A) (10 pm to 7 am) apply to measurements taken at the external wall of the residential premises closest to the noise source.
Noise generating equipment associated with the operation of the Project is mainly limited to: • the combined battery and inverter system;
• the MV transformers; and the
• the HV transformers.
Noise levels for the combined battery and inverter systems are dependent on the ‘duty cycle’ of their thermal fan systems. The duty cycle of a fan refers to the speed it is running at and the length of its running time. Generally, the higher the duty cycle, the faster the fan speed and louder the emitted noise. The fan duty cycle applied to effectively cool or heat the equipment depends on both the usage of the equipment (i.e. amount of charging/discharging) and the ambient temperature.
