Island mode earthing arrangements: New Guidance in the Second Edition of the IET Code of Practice on Electrical Energy Storage Systems
Graham Kenyon, our Managing Director, has co-authored an article with Dr Andrew Crossland, Director of Advance Further Energy Ltd, for the latest Issue 84 of the IET’s Wiring Matters industry magazine.
The article looks at earthing arrangements for electrical installations that can operate in island mode (when the mains supply is lost) when they have a battery storage system connected. Importantly, it highlights changes in the earthing requirements introduced in the 2nd Edition of the IET’ Code of Practice for Electrical Energy Storage Systems, of which Graham is co-author along with fellow industry expert Martin Cotterell.
The draft of the 2nd Edition of the IET Code of Practice for Electrical Energy Storage Systems, which our Principal Graham Kenyon co-authors, is now available for public comment on the IET web-site [link removed as consultation closed].
Comments can be submitted until 10 July 2020.
This IET Code of Practice, which brings together approaches from various standards including BS 7671 to provide authoritative and comprehensive guidance on the subject, is referenced by the recently published MCS Battery Storage Standard.
In January 2020, MCS launched its new standard for battery energy storage, MIS 3012.
The new standard, completed with the assistance of our Managing Director, Graham Kenyon, as technical author, outlines the requirements for battery storage systems that MCS certified installers will use to design, supply and install electrical energy (battery) storage systems.
Read more about the launch on the MCS website.
The standard may be downloaded from the MCS Standards and Tools Library.

Many electrical installations now incorporate new technologies, including embedded generation and home or building automation systems. As use of these technologies becomes more widespread, we need to be ever mindful that control of power to a circuit no longer relies on simple human switching operations. Electrical energy storage technologies that are capable of operating in island mode, continue to provide power when the grid is isolated.
Some incidents that have occurred recently when implementing energy storage systems outside the UK prompted Dr Andrew Crossland and myself to write an article for IET’s Wiring Matters. The article highlights the risks, and discusses safe isolation.
Further guidance on electrical energy storage systems can be found in the IET Code of Practice for Electrical Energy Storage Systems.
