BESS Failures: Study by EPRI, PNNL, and TWAICE Shows Quality Assurance and Battery Monitoring Could Prevent Majority of Failures
2024年5月15日 - 10:03PM
TWAICE, the leading provider of battery analytics software, the
Electric Power Research Institute (EPRI), and the Pacific Northwest
National Laboratory (PNNL) published today their joint study: the
first publicly available analysis of the root causes of battery
energy storage system (BESS) failures. In aggregating why battery
systems have failed in the past in an easily accessible format, the
report will help guide efforts to mitigate storage incidents in the
future and minimize BESS risk.
The report draws primarily from EPRI’s BESS Failure Event
Database to categorize failure incidents by cause and failed
element. Of the 81 events in the database, 26 had sufficient
information to establish a root cause. TWAICE engineers worked with
EPRI and PNNL to classify these failures, applying their expertise
in battery analysis to determine causes and categorize them.
Their findings ultimately showed that many BESS failures can be
prevented with better quality assurance and battery monitoring.
Contrary to popular belief, the engineers determined only three
failures could be traced to defects on the cell or module,
underscoring the need for tools that enable improved commissioning
and operational analysis of the entire system.
“Understanding the reasons behind battery storage failures is
critical for preventing them, which is why we’re pleased to help
create the first-ever public analysis of BESS incidents by cause,”
said Ryan Franks, Senior Engineer at TWAICE. “The report emphasizes
the importance of battery analytics, with most of the failures
traced to the integration and operation stages. We believe this new
resource will help guide further development of analytics software
that can ensure BESS safety. We’re honored to support EPRI in the
publication of this report and thankful for the collaboration of
their engineers and those from PNNL.”
In underscoring the importance of battery analytics and its
future development, the report lays the foundation for a more
resilient and secure energy storage infrastructure. The analysis of
failure incidents demonstrates that, while manufacturing defects do
contribute to some failures, operators must pay equal attention to
potential errors during the design, integration, and operation of
BESS units. Analytics software is ideally suited to detect these
incidents before they lead to a system failure, and the publication
of this report should help guide the development of mitigation
strategies – which include the deployment of battery analytics.
The full report can be downloaded at EPRI’s website. TWAICE,
EPRI, and PNNL will present a summary of the report at the Energy
Storage Safety and Reliability Forum at Pacific Northwest National
Laboratory from May 14-16, 2024.
