Sharon Santhosh, energy storage applications engineer at Wärtsilä, talks all things BESS noise, including enclosure design, the various mitigating measures engineers can implement, and implications of BESS technology developments further down the line.
How to reduce battery energy storage site noise?
Here are a few solutions for battery energy storage site noise reduction. Inverter units may be outfitted with manufacturer noise-reducing kits, but this often isn't enough to significantly reduce noise emissions at property lines.
Are battery energy storage systems noisy?
Ethan Brush, a technical expert from the noise and acoustics services company Acentech, recently released a study highlighting the increasing concern over noise issues associated with battery energy storage systems (BESS).
How can a Bess reduce noise?
Effective BESS noise reduction can be achieved with the inclusion of sound barriers and sound walls. Incorporating a BESS helps stabilize the energy supply to the grid and improve system voltage during times of high demand. It helps reduce power loss in the transmission network and can store excess renewable energy that would normally be curtailed.
What is equipment noise data?
The equipment noise data will be used to generate a model of the total facility's sound emitted at the property line and at sensitive receptors such as homes. The model includes all necessary equipment sound sources along with topographical features of the surrounding area.
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.
How can Acentech reduce the noise from Bess installations?
Like solar and wind energy sites, Acentech is positioned to be a national resource for mitigating the noise from BESS installations so that they can be properly sited per local regulations, and to reduce the risk of community annoyance.
