Safety of Grid-Scale Battery Energy Storage Systems

Page | 005

• There are numerous international standards which regulate the design, manufacture and distribution of lithium-ion batteries to ensure they are adequately tested for safety, reliability and durability (detailed further in Section 3).
• Safety is fundamental to the development and design of energy storage systems. Each energy storage unit has multiple layers of prevention, protection and mitigation systems (detailed further in Section 4). These minimise the risk of overcharge, overheating or mechanical damage that could result in an incident such as a fire. There are also international best practice guidelines for industry to aid developers in the design and operation of battery storage systems in a safe and secure manner. A global approach to hazard management in the development of energy storage projects has made the lithium-ion battery one of the safest types of energy storage system.
