Every data centre incident in public reporting that started in the power systems: UPS and battery rooms, backup generators, switchgear, transformers and fuel. Each entry says what happened and lists its sources. Free to read.
The Energy Incident Register is a data contributor to the PV Fire Intelligence Network (PV-FIN) , led by BRE, and has been reported by DatacenterDynamics (DCD) .

Where the reporting names the part that failed, UPS and battery rooms come up most often: 22 of the 92 entries, then backup generators (15).
52 of the 92 entries are fires or thermal events, and 17 are classed as major.
46 of the 92 entries are dated 2024 or later.
Counted from the words of the reporting itself. An entry is counted under each part its reporting names, and "Not stated" means the public reporting did not say.
The entries the register classes as major: the longest outages, the worst damage and the incidents where people were hurt.
Every data centre entry
How many data centre fires have there been?
The register holds 92 data centre incidents from public reporting, 2010 to 2026, in 27 countries. 52 of them are fires or thermal events; the rest are power failures, explosions, gas releases and electrical injuries in the power systems. These are the incidents that reached public reporting; many smaller ones never do.
What causes most data centre fires?
Where the public reporting names the part that failed, the most common is UPS and battery rooms (22 entries), followed by backup generators (15) and switchgear and electrical rooms (10). In 52 entries the reporting does not say what failed.
Do lithium-ion UPS batteries cause data centre fires?
6 entries name lithium-ion batteries, including Lithium-ion battery explosion causes data centre fire in Daejeon (EIR-1893, 2025); Battery room fire at Digital Realty data centre in Hillsboro, Oregon (EIR-0106, 2025); Explosion and multi-day fire at SIN11 Digital Loyang 1 data centre, Singapore (EIR-0116, 2024). Lead-acid UPS batteries appear too. Each entry gives the source for what was said.
Which data centre incidents were the most serious?
17 of the 92 entries are classed as major, among them Reported fire at an AWS data centre in Bahrain after alleged attack (EIR-1897, 2026); Fire reported at an Amazon data centre site in Jerome Township, Ohio (EIR-1958, 2025); Lithium-ion battery explosion causes data centre fire in Daejeon (EIR-1893, 2025). The full list is on this page.
Where do data centre fires happen most?
In the reporting the register has found, United States (33), United Kingdom (14), India (5) have the most entries. That partly reflects where data centres are built and where the press reports on them.
Is there a list of data center fires?
Yes. This page lists every data centre (data center) fire and power failure the register has published, 92 entries from 2010 to 2026, each with its sources, free to read and cite. It is rebuilt from the register as new incidents are published.
What this page covers, and what it does not
The register records incidents in a data centre's power systems, because those are the parts that their failure modes with battery storage and the grid: lithium-ion and lead-acid UPS batteries, diesel generators and their fuel, switchgear and transformers. A software outage or a cooling fault with no fire or power failure is not recorded here.
Public reporting on data centre fires often names the operator but rarely the battery chemistry, the UPS make or the cause. The register does not guess them. Where a fire service, regulator or the operator states one, the entry carries it and says who said it.
If you run data centres or insure them and want a field added, tell us what it should be .
For data centre operators, their insurers and lenders
A submission tells you what the broker chose to include. The register tells you what has been reported the site, the operator and the equipment, with the source for every line, and a modelled cost and downtime range where no figure was published.
Each entry: the site and operator where the source names them, what happened, the contributing factors, the lessons and every source. Never a person. A spreadsheet of the whole set arrives when you confirm an alert sign-up on this page.
