Electrical Energy Storage Systems Unit 5: Specification of an EESS – Key Factors and Battery Life
This unit provides a detailed study of three of the most important technical parameters surrounding an electrical energy storage system: capacity over life, efficiency and power. These are important throughout the whole life of an electrical energy storage system and as such are useful when specifying a system and comparing different problems/designs.

Director and Principal Consultant at G Kenyon Technology Ltd, Graham has established his reputation designing and implementing control and information management systems in the challenging environments presented by world-class construction programmes in the airport and railway industries.
Graham is well versed in standard-setting, as he serves as Chair of both the IET’s Wiring Regulations Policy Committee and JPEL/64 Sub-Committee D for BS 7671, and is a member of the CIBSE’s Electrical Services Group Committee. He has supported many other committees during his involvement with IET Standards.
Graham is co-author of the IET Code of Practice for Electrical Energy Storage Systems, author of the IET Code of Practice for Electric Vehicle Charging Equipment Installation, and editor of some of the IET’s Wiring Regulations publications: Guidance Note 5 Protection against electric shock (8th Edition); Guidance Note 6 Protection against overcurrent (8th Edition); and Electrical installation design guide (4th Edition).
Dr Andrew F Crossland CEng PhD MEng. Andrew is a specialist in interdisciplinary modelling - combining social, financial and technical modelling to develop and deliver energy projects. He has worked in the railway, electrical distribution, research and solar industries developing new techniques and models for the rapidly changing, and increasingly low carbon energy mix. He won the Energy UK “Rising Star” Award for his work in the sector in 2017.
Andrew founded the energy tracking system MyGridGB, charting the British electricity mix, carbon emissions and fossil fuel consumption in real time. Through this he works to provide an unbiased view of the potential and contribution of different energy sources.
As an Energy Storage Specialist for three years at SolarCentury, Andrew helped to developed on residential, large battery and microgrid projects in the UK and East/Southern Africa. Andrew was also Chair of the Behind the Meter Energy Storage Group at the Solar Trade Association at this time.
In 2018, Andrew joined Infratec in New Zealand working on energy projects across New Zealand and the Pacific. He is also a director of Advance Further Energy Ltd which provides specialist energy storage consultancy services in the UK.
