Energy storage cabinets are noisy

Are battery energy storage systems causing noise?

Battery Energy Storage Systems (BESS) are relatively new to the US, and communities are only just starting to become aware of the noise issues they can create. BESS’s are generally large power storage facilities, often comprised of hundreds of battery units the size of shipping containers spread over many acres of land.

Why does a Bess battery make a loud noise?

In our work with BESS, the noise is commonly associated with the battery and inverter modules’ heating and cooling systems, with the use of fans and compressors being the main emitters. However, the noise levels emitted are highly variable and depend on several factors, including operating conditions, ambient temperatures, and speed drives.

What makes a Bess a noisy facility?

This noise is often tonal, which can mean the facility noise levels are held to a more restrictive noise limit. Power Conversion System (PCS): The PCS is an essential component of the BESS as it converts electricity between direct and alternating currents.

Does your battery storage facility comply with the city's 45 dBA nighttime noise requirement?

We were able to demonstrate the facility complied with the City’s 45 dBA nighttime noise requirement. If you want further advice on battery storage facility noise issues or have already decided to take action and need a noise output tested and analyzed, contact Noise Monitoring Services today on (323) 546-9902.

Did NMS conduct a noise study for a new battery energy storage facility?

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.

What are the main noise sources from a Bess facility?

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.
