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.
On 2nd February 2021, our Managing Director, Graham Kenyon, is joining John Peckham, of Astute Technical Services Limited, to provide an insight into the requirements of an electrical design role. The presentation will cover the fundamental principles of BS 7671, and review the duties on some other legislation and standards for electrical installation designers.
The event will be hosted by Colin Penfold, of the Operations department of Defra, and Colin, John and Graham will be answering live questions raised during the Webinar.

Title: Responsibilities for those in an electrical installation design role
Date: Tuesday 2nd February 2021
Time: 3 pm GMT
Duration: 1 hour 30 minutes
** now updated to BS 7671:2018+A1:2020, and the 4th Edition of the IET Code of practice for electric vehicle charging equipment installation **
G Kenyon Technology Ltd, as a content partner with the IET Academy, has developed an on-line course for designers and installers of Electric Vehicle Charging Equipment Installations.
Learn on-line, at your own pace
This course will cover: the design of electrical installations for, and specification of, electric vehicle charging equipment installations; the requirements detailed in Section 722 of BS 7671:2018; and recommendations of the IET Code of Practice for Electric Vehicle Charging Installations, 3rd Edition. It provides an understanding of the key requirements for protection against electric shock, including selection and use of earthing systems, and introduces vehicle-as-storage, wireless power transfer (WPT) and smart infrastructure installations.

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.

Interest in utilising d.c. power systems within buildings is on the increase, for various applications relating to:
- Distributed / local energy generation and storage
- Electronic devices
- Data centre installations
- LED lighting
Our Principal, Graham Kenyon, has written an article for the IET’s Wiring Matters, which discusses the challenges that are presented by what could be seen as a change of direction for wiring systems in buildings.
