Wärtsilä’s battery energy storage system (BESS) product Gridsolv Quantum has achieved the “best possible outcome” in UL9540A testing.

Cameron Murray talks to industry experts about the physical security risks to battery storage sites, and how the security and insurance aspects of operating BESS sites are evolving.

The second high-profile battery storage failure due to a faulty sprinkler system could mark the beginnings of exclusions from insurance policies if certain providers develop a negative track record, a source said.

The faulty activation of sprinkler system forced the decommissioning of the LG batteries which were eventually stolen from Terra-Gen’s Valley Center BESS in California, the company told Energy-Storage.news.

Energy storage’s incredible versatility and usefulness can’t be fully unleashed without a comprehensive approach to fire safety.

The battery storage industry can learn lessons on how to approach fire safety from more established sectors as it works to develop standards.

We hear from two battery storage insurance industry sources about how they view the technology and the main risks they assess when designing policies.

Some proposed battery storage projects have been cancelled in the US and Canada since the start of this year, after facing opposition from local communities.

CATL is working with ‘safety science’ specialist UL Solutions on the safer deployment of batteries for stationary storage and transport applications.

Further attempts are being made to recall batteries thought to pose fire risk through overheating in Australia, with thousands of home energy storage systems believed to be affected.
