What happened

On 2 August 2017 a lithium ion battery energy storage system, part of the Gochang wind integration BESS installed for wind integration purposes in Gochang, North Jeolla province, South Korea, experienced a failure incident. The system had an energy capacity of approximately 1.5 MWh and was outdoor mounted. According to the EPRI BESS failure incident database, the system was newly installed with an age of zero years at the time of the incident, indicating the failure occurred at or shortly after commissioning.

No further details on the nature of the failure, injuries, fire response or damage were available from the source consulted. This entry has been drafted from a database summary only, as the underlying article text could not be retrieved.

Lessons learned

  1. New lithium ion BESS may fail at or shortly after commissioning, so operators should carry out full testing before energisation.
  2. BESS used for wind integration need the same safety reviews as standalone storage projects.
