I have received a response from National Grid ESO to some of my questions on the Early Outlook for Winter 2022. In this post I update my analysis and add some further commentary on the risks to energy security this winter. Reliance on interconnectors [...]
Today National Grid ESO has published its early view of the Winter Outlook for 2022/23. Unbelievably, it believes the capacity margin will be slightly higher than last year at 4.0 GW compared with 3.9 GW. This strikes me as extreme wishful thinking which does [...]
There has been a lot of noise recently about the prospect of a move to some form of location-based pricing in the GB electricity market. National Grid ESO is strongly in favour, seeing nodal pricing alongside a return to centralised dispatch as the best [...]
In my previous post I looked at Ofgem’s network charging reforms. Here I will summarise the conclusion of the Significant Code Review into network access (now known as the “Access SCR”), which was originally part of a wider review into network access and forward-looking [...]
One night last week I had a dream that hydro-power isn’t generated by water, but by a mouse called Lucy which is getting tired, with dire consequences for the market. The dream made more sense than the tangle which is known as network charging [...]
This month the Government and Ofgem have announced the creation of a new system operator to manage both the gas and electricity transmission systems in Great Britain. Dubbed the “Future System Operator”, the organisation will be publicly owned and involves the nationalisation of National [...]
In October, the 1,400 MW interconnector between Britain and Norway, known as the North Sea Link, began commercial operations. The €1.6 billion project is a joint venture between National Grid and Norwegian system operator Statnett. Unlike the other markets with which Britain is linked, [...]
Several people have reached out to me today asking me to comment on Ofgem’s announcement about the SOLR cost recovery, so I’m writing this quick blog on the subject. Back in October, Ofgem published a letter setting out its plans to make temporary changes [...]
While Britain has been struggling with unprecedented retail market chaos, there have been unprecedented events of a different sort on the other side of the world in South Australia, which saw negative demand on the transmission system for the first time ever. In fact [...]
Last week National Grid ESO announced that it has begun to use a novel new tool for measuring grid inertia. One of the challenges of managing an electricity system with a large amount of intermittent generation is maintaining grid frequency within operational tolerances. If [...]
