The noise of battery energy storage system (BESS) technology has "exploded" as a concern in the last six months, an executive from system integrator Wartsila ES&O said.
As energy storage sites expand, managing noise pollution becomes critical. Discover innovative technologies and design strategies that minimize sound impacts while maintaining high-performance energy storage solutions.
"NFPA 855" the Standard for the Installation of Stationary Energy Storage Systems, provides comprehensive guidelines for the safe installation of stationary energy storage
However: The day, evening and night RBLs measured at the location are above the Typical existing background noise levels for a Rural Residential Receiver, with the night RBLs being in line with the ·Typical existing background noise levels for Urban Residential Receivers; The NCA is within close proximity vicinity of industrial noise sources
Grid-scale battery storage has the potential to significantly assist in the renewable energy transition. Noise has emerged as a key environmental impact challenge in the development of BESS.
Darren Lafon-Anthony, Director of Acoustics at Enzygo Ltd looks at noise generated by BESS facilities, the potential impact on the environment and mitigation measures available to reduce noise impacts and target noise levels at receptors.

While the sound power level of a source is fixed, the sound pressure level depends upon the distance from the source. Both are measured in dB so can be easily confused.
The noise modelling assumes that during daytime and night-time periods all battery storage HVAC, inverters, transformers and switchgear plant are in operation and therefore the noise predictions provide an indication of the highest likely noise level.
These battery energy storage systems typically consist of rechargeable batteries, power conversion systems, cooling systems and control electronics. BESS facilities tend to produce high noise levels generated mostly by the compressors and fans in the electrical equipment cooling systems.
When planning for a battery energy storage site, it is important to enlist the help of acoustical consultants to navigate the regulatory process surrounding noise and ensure the right noise controls are implemented.

BESS units primarily emit noise from their cooling systems, but balance of system (BOS) components like inverters and transformers also produce noise emissions.
In July, 2022, NMS was retained to conduct a detailed noise study for a new Battery Energy Storage Facility near Los Angeles (for confidentiality purposes, no identifying client or site information is included in this article). The facility consisted of over 300 batteries, over 60 PCS units and two transformers covering about 6 acres of land.
Batteries: Rechargeable battery units are the core of the Battery Energy Storage System. Battery units (often 20 ft. in length and 8 ft in width and height) include cooling systems to maintain optimal operating temperature. The cooling systems use fans and condensing units which can generate noise levels up to 92 dBA at 1 m from the equipment.
Substation. Noise emissions from these items of equipment varies widely depending on size, operating capacity, outdoor temperature, and equipment supplier. Battery Container Battery containers generally make little noise during normal operation when external ambient air temperatures are in the 5°C to 25°C range.
The main noise sources from a BESS facility are: Like any electronic device, grid-scale battery systems operate most optimally and safely at an ideal temperature and humidity. Therefore, various air or liquid cooling and heating systems are used.
Depending on the capacity of the BESS, a substation contains a variety of noise generating elements the main one of which will be the transformer with fan assisted cooling with other elements contributing lower noise levels.
