ESS Fire-Safety Kits Across 20 Sites — What the System Must Prepare
GFI has won a KRW 15.9 billion contract for Samsung SDI's North American ESS fire-safety solution. It will install DI-KIT at 20 sites by 2027. This contract shows that fire-safety devices are being ordered not as a cell-level option but as a site-level system line item. On the operations side, what is needed first is defining the installation sequence across the 20 sites and the interface with existing systems. 1. What Happened To state the conclusion first: ESS fire-safety solutions have moved into a phase of being applied in bulk across multiple sites. Until now, the general approach for North American ESS was to address site-specific safety requirements individually. Bundling…

NFPA 855 (2026 Edition) Revision: ESS Safety Standards Expand From the Cell to the Entire System
Since August 2017, 21 lithium-ion battery ESS fires have occurred in Korea alone, but only a portion of these incidents can be explained by battery cell defects alone. In many cases, the direct cause of fire spread was equipment outside the battery itself — the Balance of System (BOS) — such as missing surge arresters, defective wiring installation, or cooling/HVAC failures. With the release of the 2026 edition of NFPA 855, the National Fire Protection Association (NFPA) has shifted its evaluation criterion from "whether an internal cell defect exists" to "whether propagation to adjacent cells, modules, or racks is blocked." NFPA 855 is the Standard for the Installation of Stationary…
