Energy storage power station noise

Are battery energy storage systems causing noise?

Image: Wartsila. 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. BESS units primarily emit noise from their cooling systems, but balance of system (BOS) components like inverters and transformers also produce noise emissions.

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.

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.

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 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.

What are the noise generating elements in a Bess substation?

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.
