Electrical Energy Storage Systems (EES). Part 5-2: Safety Requirements for Grid-Connected EES. Electrochemical Systems

This document establishes essential safety requirements for electrochemical energy storage systems integrated into electrical grids. It specifically addresses the fifth part of a broader series focused on electric energy storage systems, detailing technical criteria necessary to ensure the secure operation of such installations. The scope covers the design, construction, and operational parameters that mitigate potential risks associated with large-scale electrochemical storage connected to the utility network. By defining clear safety protocols, it aims to prevent hazards such as thermal runaway, electrical faults, and other failures that could compromise grid stability or public safety. The content provides guidance applicable to system developers, integrators, and operators who must adhere to these specifications during the lifecycle of the storage facility. It serves as a technical reference for aligning domestic implementations with recognized international safety benchmarks, ensuring consistency and reliability across interconnected energy infrastructure without imposing direct evaluation or commentary on its strategic value.
