As part of today’s reformed national pricing process, there is an acute focus on reducing network curtailment, the renewable generation we have to switch off due to grid constraints, and the cost of replacing it with non-renewable generation elsewhere. In this working paper, I look at a different type of curtailment: oversupply of renewables, when […]
The Administrative Strike Price (ASP) for wind has risen sharply this round. The main driver? It appears to be lower assumed load factors in DESNZ’s modelling — a change that appears to add between £19/MWh and £33/MWh. Several changes complicate AR6 vs AR7 comparisons: AR6 assumed a very high offshore wind net load factor of
Over several months I worked with the brilliant CS team to explore what good consumer outcomes look like for the climate transition, how tensions should be balanced, and how to lay out a framework to support government decision making.
The objective of this paper is to review a wide range of options that could be incorporated into a reformed national market and help the government make a well-informed decision on which market structure to take forward.
This project explores the question of how much capacity on the national, main transmission network is economically efficient given the likely capacity, type and spatial distribution of generation and the magnitude and location of demand in a decarbonised electricity system.
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,
