TWAICE, the leading provider of battery analytics software, Electric Power Research Institute (EPRI) and Pacific Northwest National Laboratory (PNNL) published today their joint study: the most recent, comprehensive publicly available analysis of the root causes of battery energy storage system (BESS) failure incidents.
Battery energy storage system (BESS) failure is being investigated heavily because of how disastrous BESS failures can be, and how important BESS is to the future of the grid. A joint study commissioned to analyze root causes of BESS failures underlined the impact of battery monitoring more than battery cell defects.
The focus of the database is on lithium ion technologies, but other battery technology failure incidents are included. Failure incident: An occurrence caused by a BESS system or component failure which resulted in increased safety risk. For lithium ion BESS, this is typically a thermal risk such as fire or explosion.
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
Note that the Stationary Energy Storage Failure Incidents table tracks both utility-scale and C&I system failures. It is instructive to compare the number of failure incidents over time against the deployment of BESS. The graph to the right looks at the failure rate per cumulative deployed capacity, up to 12/31/2024.
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.
PoF is not the only type of physics-based approach to model battery failure modes, performance, and degradation process. Other physics-based models have similar issues in development as PoF, and as such they work best with support of empirical data to verify assumptions and tune the results.
Nairobi, Kenya – July 2025 — The Kenya Electricity Generating Company (KenGen) has officially commissioned its first Battery Energy Storage System (BESS) to power a modular data center in Nairobi, marking a major milestone in the country's clean energy transition. First reported by the Citizen, the system, which has a capacity of 1. Digital Resilience: The BESS. Kenya's plans to host a $1 billion data centre backed by Microsoft and UAE-based G42 have stalled, after President William Ruto said the country lacks sufficient power capacity to support the project.

Telecom operators and banks seek high-performance infrastructure to support core applications. Rising e-governance adoption.

This paper presents a techno-economic optimization model to analyze the economic viability of a photovoltaic battery (PVB) system for different residential customer groups in Switzerland clustered based.
The Kenya Electricity Generating Company is piloting use of a Battery Energy Storage System for uninterrupted renewable power, marking a new frontier in Kenya's green energy strategy.
The Cabinet has approved new energy and petroleum policies and a transport financing model, as President Ruto cites daily load-shedding and targets 10,000MW capacity and revived road and rail projects. key driver for economic growth. With over 25% of the population still lacking. The National Energy Policy 2025–2034 is therefore a tool in spearheading our country's vision of equitable energy transition, focusing on innovation, resilience, and sustainability to meet the needs of all Kenyans. They have fostered regulatory reforms and incentivized investment in the energy sector and laid the foundation for energy governance in the country bot nd 9. However, when examined critically, the policy reveals key gaps — particularly regarding its environmental commitments and the protection of community rights. This policy must reflect the fact that we need to.
