failure due to a defect in an element of an energy storage system introduced in the manufacturing pro-cess, including but not limited to, the introduction of foreign material into cells, forming to incorrect physical tolerances, or missing or misassembled parts.
In general, energy that is stored has the potential for release in an uncontrolled manner, potentially endangering equipment, the environment, or people. All energy storage systems have hazards. Some hazards are easily mitigated to reduce risk, and others require more dedicated planning and execution to maintain safety.
This report conveys the lessons learned from the Carnegie Road energy storage system (ESS) failure event in the UK, including aspects of emergency response, root cause investigation, and the redesign and rebuild processes.
Interest in storage safety considerations is substantially increasing, yet newer system designs can be quite different than prior versions in terms of risk mitigation. An uncontrolled release of energy is an inevitable and dangerous possibility with storing energy in any form.
Root Cause of Failure: Design, manufacturing, integration/assembly/construction, or operation. Affected BESS Element: Cell/module, controls, or balance of the system. The study analyzes the proportion of failures associated with each root cause and BESS element, the relationship between the two, and trends in failure types and rates over time.
Battery Energy Storage Systems (BESS) have become integral to modern energy grids, providing essential services such as load balancing, renewable energy integration, and backup power. However, as with any complex technological system, BESS are susceptible to failures impacting their performance, safety, and reliability.
