Networks
Last week I had the pleasure of being one of the keynote speakers at the Institute of Directors Guernsey Branch annual convention, speaking about energy policy options for the Bailiwick in the context of climate ambitions. The day before, the States had published a [...]
Ofgem is in the process of reforming the way in which users pay for access to and use of electricity networks, which I have described in previous posts here and here. The Targeted Charging Review is the more advanced project and is tackling reform [...]
Ofgem has now published National Grid’s technical analysis of the 9 August blackout. Much of the meat is contained in the appendices. The report does not answer many of the questions that have been asked in relation to the incident, and throws up a [...]
National Grid has now published National Grid ESO’s initial report into the 9 August blackout. The extremely repetitive 26-page report sheds some new light onto the events on the day (and I was rather gratified to see that my hunch relating to Hornsea tripping [...]

On Friday evening, there was a widespread power blackout across many parts of the UK, with transport systems in particular being affected. Supplies were restored within an hour although the transport problems took far longer to resolve, with the knock-on effects of delayed trains [...]

The rapid deployment of renewable generation, and its impact on the electricity system in terms of transmission capacity management, balancing intermittency and frequency control has triggered the need for an entirely new suite of flexibility products. At the same time, the opportunities to earn [...]
The consultation into Ofgem’s minded-to decision in its Targeted Charging Review into residual network charging and embedded benefits closed this week with strong objections being made by renewable and distributed energy bodies who see the proposals as damaging the business models for small embedded [...]
Ofgem is exploring major changes to electricity network charging and access arrangements that will affect all users of the system from large businesses to households, from large transmission-connected to generation to behind-the-meter storage operators. In this second post on network charging and access reform, I [...]
