Noise test of energy storage equipment

Are battery energy storage systems noisy?

chris@ parkerjonesacoustics.com As Battery Energy Storage Systems (BESS) become increasingly prevalent in the UK, it is crucial to address the potential noise concerns associated with their operation.

What are the key components and noise sources of a Bess facility?

Key components and noise sources of a BESS facility include: 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.

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 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.

What are battery energy storage systems?

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.

Why is noise a key environmental impact challenge?

Noise has emerged as a key environmental impact challenge in the development of BESS. But why? 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.
