COVID-19: A Message from the IET Journals Team We would like to reassure all of our valued authors, reviewers and editors that our journals are continuing to run as usual but, given the current situation, we can offer flexibility on your deadlines if you should need it. Our systems are set up to work to fixed timescales and may issue automatic reminder emails – please do not hesitate to get in contact with us at [email protected] if you need an extension or to discuss options. We recognise the tremendous contribution that you all make to the IET journals and would like to take this opportunity to thank you for your continued support.

IET Energy Systems Integration is a Gold Open Access multi-disciplinary journal that covers the integration of multiple energy systems (e.g. electricity, nature gas, heating, cooling, hydrogen, and low-carbon transport), at various scales (from multinational, national, community scale down to building level) and across the energy supply chain (from energy conversion, transmission, distribution down to consumption). The journal publishes original research findings, the latest perspectives from research projects and technology development, and systematic reviews in the field of energy systems integration.

The topics of interest include, but are not limited to:

Energy Apparatus for ESI

• Design, modelling and validation of energy apparatus for ESI

• Artificial intelligence, cyber security, and cyber-physical systems applied in energy apparatus

• Standards of advanced energy apparatus

Technologies of Individual Energy Vectors for ESI 

Technologies of:

• Electrical networks for ESI

• Natural gas networks for ESI
