Code of Practice for Electrical Energy Storage Systems (IET Codes and Guidance)

Electrical Energy Storage Systems (EESS) provide storage of electrical energy so that it can be used later.EESS may be installed for a variety of reasons, for example increasing the 'self-consumption' of buildings fitted with renewable energy systems; arbitrage services; ancillary services and providing a back-up or alternative power supply. This Code of Practice looks at EESS applications and provides information for practitioners to specify safely and effectively, design, install, commission, operate and maintain a system. The scope of this Code of Practice includes EESS intended for fixed installation applications including: individual dwellings,commercial applications, including multi-occupancy buildings and multi-occupancy residential buildings,industrial applications, and covers: electrochemical energy storage systems in electrical installations,integration into low voltage (LV) power systems (AC and DC) and,systems aligned with existing standards, regulations, and guidance.
