ESIC Energy Storage Commissioning Guide

This report updates the previously published Energy Storage Integration Council (ESIC) Energy Storage Commissioning Guide 2018. In order to align with the rapidly changing energy storage technology space, these guidelines were refined to address how commissioning can be most efficiently addressed and executed in terms of project costs, safety, and schedule. Field experiences, lessons learned, and recent codes and standards updates that influence storage system commissioning were considered and adopted through a structured process involving the ESIC Working Group 3 Commissioning Task Force. Recent learnings influence the need to address commissioning intricacies from all stages of project development; commissioning needs to be assessed from the initial stages of project conception and efforts need to be identified, refined, assigned, budgeted, and scheduled appropriately in a continual effort until commissioning takes place. Failure to do so exposes the storage project to added costs and schedule delays. Decommissioning and recommissioning, which has become a focus area for many aging energy storage projects is also explored. This report presents considerations for all stages of project development, from inception to decommissioning as well as details on how numerous entities may be involved, the efforts of each, and the interdependencies between these entities.
