Trusted, independent validation of battery energy storage system performance and operating characteristics

SHARE:

Any battery energy storage system (BESS) must operate in line with industry expectations and contractual obligations. And project financiers require proof of this before investing. Therefore, it is essential to provide credible validation of your BESS project’s capabilities.

Identifying performance and beneficial characteristics
As part of our broad independent engineer’s (IE) technology review services, DNV offers independent operational performance assessment for BESS assets and portfolios. This helps you identify asset performance with respect to application specific expectations and equipment warranties. It also shows you operating characteristics that are beneficial for asset life.

We review your BESS project documentation and operational data to identify key operating parameters such as temperature, power, c-rate, state-of-charge (SOC) variation, efficiency and degradation. This can include site visits and capacity test witnessing. The service also forms a necessary component of the technology due diligence requested by project financiers.

The operational performance assessment can be coupled with our battery Degradation assessment service. Thereby allowing you to identify battery capacity maintenance needs or make adjustments to battery operations. Trusted assessments We have performed numerous assessments for solar + energy storage portfolios. Equipped with comprehensive technical expertise, our engineers deliver independent reviews that are trusted globally.
