In 2018-19 the average cost to resolve a thermal constraint in the GB power system was £109 / MWh. In 2022-23 it was £366 / MWh. The reason for the more than three fold rise? The increased cost of turning up gas power stations to replace curtailed renewable output. It is widely accepted that our …

Scottish Futures Trust have published a piece of work I carried out earlier in the year developing a vision laying out how to reform of our electricity market and the way we develop our electricity system. https://shorturl.at/btEHW The vision is predicated on the idea that delivering significant renewable generation capacity is important for net zero, …
A £25/ MWh locational difference in transmission charges for wind by the early 2030s? National Grid ESO published ten year TNUoS forecasts this week giving an illustration of what transmission charges would look like under the current methodology out to 2034. Although the values are published in pounds per kilowatt of installed capacity I often …

I enjoyed the discussion at today’s Scottish Renewables hashtag#onshorewind23 conference “Pounds and Pylons” session. I thought I’d share my key slides for those interested. They highlight the potential size of the gap between Scottish renewable supply and the ability to do something with today and in the future it if we don’t get a better …
Authors: Simon Gill and Keith Bell. The full blog post is available on the UKERC website Development of low carbon electricity generation capacity on a level never seen before is required over the next two decades both to decrease the emissions intensity of electricity production and meet growing demand. Although a fair amount of new …

Thanks to Scottish Renewables for inviting me to speak at the Net Zero Conference yesterday as part of the grid integration session. My topic was the importance of flexibility to integrating clean resources into the electricity grid. It was a chance for me to get out my ‘where is energy stored in our energy system’ …
The current review of wholesale electricity market arrangements has the potential for a significant impact on Scotland’s energy system. To help get to grips with this complex area I’ve written a briefing note – “Review of electricity markets arrangements: what does it mean for Scotland?” 👇👇 It has been produced in conjunction with Scottish Futures Trust …
Authors: Simon Gill, Keith Bell and Callum MacIver Extended Blog post: Available on the UKERC website Report document, including executive summary, full report and stakeholder engagement summary available via the University of Srtathclyde. Along with Keith Bell and Callum MacIver I’ve spent much of the past six months trying to understand the workings ofLMP. We’ve …
Visualising the whole energy system: I was delighted to see The Scottish Government publish two energy system maps as part of the recent draft Energy Strategy and Just Transition Plan. These aim to lay out an infrastructure view of the whole system. Whilst working at SG I designed these maps with teams covering all aspects …
It was great to be part of the launch of Go West! a project I helped kick off with Regen in Spring. The final report highlights the value of a geographically diverse hashtag#offshorewind fleet. It shows the importance of spreading wind capacity around our whole coastline. Delivering that diversity will mean focusing specifically on how …
