Enabling the DSO transition - A consultation on the ESO’s approach to Distribution System Operation (2021)

Former Community Member

This is an opportunity for a more coordinated approach in the development of the whole electricity system, through joined-up thinking and application of systems engineering principles. Read our response to the Energy System Operator (ESO) consultation.

We believe:



  • A truly ‘whole (electricity) system’ approach requires a broader perspective.

  • Community energy enterprises (physical or virtual), energy hubs and individual customers (enabled by technology), will have an increasing influence on physical energy flows across distribution, and ultimately transmission networks.

  • Greater consideration is needed, as to the important role that flexibility from Distributed Energy Resources (DERs) will play in the wider electricity, and ultimately whole energy system.

  • ESO and DSOs must continue to evolve systems and processes that minimise inconsistencies, including applying sensitivity analyses to better understand the potential impact of any unresolved differences.

  • A more fundamental review of industry code governance is required.

    To be fair the only place I have seen 690/1k2 up close was in Germany in a large manufacturing site run by Siemens, and there were indeed transformers in a number of odd places. The huge advantage over 11kV is that both sides of the transformer are (well almost) LV and that makes it easier to work with, as cables, switches, contactors, breakers etc. seemed to be nothing extra special, certainly not like we, or they, would have required for full blown HV.

    I suspect that they can buy enough to lean on the makers to get a  cables and things normally marked as  600/1000 proof tested and certified for a bit more... It is really unnerving to see what looks like really super weedy cables - 3 phase in 2.5mm doing something like 55kW  instead of 18 and oh the length!  - right to the far end of the hanger and nary a flicker .. Which is why they did it of course...

    Their 400/690 was more like 380/660, but then their 230 is really 220 so it is not really a fair test.

    In the UK I do not know, I suspect there is not that much 400/690.

    My real point is that for interlinking substations that are already spaced apart based on volt drops at 230V, you need more volts to make it work. I realise this is not true in London, where they are so close they can LV mesh, but we do not all live in London.
