Common Problems in Container Energy Storage Commissioning

What are the biggest concerns in battery storage systems?

For its “BESS Pros Survey”, battery analysis software maker Twaice surveyed experts about their biggest concerns in the commercial operation of battery storage systems (BESS). System performance and availability concerned the battery professionals the most. They also highlighted technical issues interrupting day-to-day operations as a problem.

What are the commissioning requirements?

The following commissioning requirements will be verified during the commissioning process: specifications, codes and standards, safety requirements, applications, and testing. In the Procurement and Design phase, a vendor/contractor is chosen, i.e., a bid is accepted by the owner for construction and installation of the system.

Do energy storage subsystems have to pass a factory witness test?

Each subsystem must pass a factory witness test (FWT) before shipping. (Note: The system owner reserves the right to be present for the factory witness test.) This is the first real step of the commissioning process—which occurs even before the energy storage subsystems (e.g., power conditioning equipment and battery) are delivered to the site.

What information should be collected after the commissioning process?

After the completion of the commissioning process, it is important to collect all the test results and baseline measurements into a singular closeout document. This information can be referenced during future maintenance activities to provide information about potential changes in the system or operation.
