Focusing on Battery Energy Storage Systems (BESS)

Heyda Provides Expert Noise Assessment Services for BESS Facilities

The emergence of new technologies such as Battery Energy Storage Systems (BESS) brings the challenge of assessing their impact on the acoustic environment. This post outlines the process of conducting an acoustic assessment, following the guidelines of BS 4142:2014+A1:2019 and local authority requirements.

BESS Noise Assessment

Understanding the Framework

BS 4142:2014 provides a method for rating and assessing sound of an industrial nature, like that potentially produced by BESS. It helps determine the impact on nearby sensitive receptors, typically residential properties. Local authorities also set specific requirements, which often align with BS 4142 but may include additional criteria.



The Assessment Process

    1. Initial Site Survey and Baseline Noise Levels: The assessment typically begins with a site survey to understand the existing noise environment. Baseline noise levels are measured, typically over a representative period, to establish the pre-existing sound landscape without the BESS operational.

    2. Identifying Noise Sources and Potential Impact: Key components of the BESS that could generate noise are identified. This includes cooling systems, transformers, and any associated infrastructure. The potential noise impact from these sources is considered in the context of the nearest noise-sensitive receptors.

    3. Predictive Modelling: Using data from the manufacturer and empirical data, acoustic consultants predict the noise levels that the BESS will generate. This modelling considers factors like distance to receptors, topography, and intervening structures.

      • BS 4142:2014 Rating Method: The predicted noise levels are then rated according to BS 4142:2014. This involves comparing the predicted noise levels against the baseline levels, with adjustments made for tonal, impulsive, or intermittent characteristics of the noise.

      • Local Authority Requirements: Alongside BS 4142, the specific criteria set by the local authority are also considered. These might include more onerous noise limits or additional assessment for certain noise characteristics.

    4. Mitigation Strategies: If the assessment indicates a potential adverse impact, mitigation strategies are developed. This could include acoustic barriers, repositioning of components, or modifications to the BESS’s operational parameters.

    5. Reporting and Liaison with Authorities: A detailed report is prepared, outlining the assessment process, findings, and recommendations. This report is submitted to the local authority as part of the planning process. Effective communication with the authorities ensures that all concerns are addressed and compliance is achieved.

Post-Installation Monitoring

After the BESS is operational, post-installation monitoring may be conducted to verify that the actual noise levels align with the predictions. If discrepancies are found, further mitigation may be required.
