Investability and Scottish wind: the narrow path to ensuring onshore wind in Scotland is viable

Is an onshore wind farm in Scotland investable in early 2025? It is an important question. Clean Power 2030 needs 13 GW of new onshore wind by 2030, potentially 10 GW in Scotland. Full details, the report and the open source spreadsheet are available via Regen’s website. My answer, in this ‘open-source’ paper produced with […]

Getting interconnectors right for net zero

Electrical interconnectors linking Britain with our neighbours will be critical in a net zero electricity system. They will enable renewable generation across the country by ensuring a market for an increasing fraction of their generation. Interconnectors will also be essential to ensure a secure supply of electricity, something that will become increasingly important as we

How far does the power need to go? The impact of GB-wide transmission network capacity on wind curtailment and access to low carbon electricity

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.

Exploring the implications of locational marginal pricing of electricity

A wholesale market based on ‘locational marginal pricing’ (LMP) has long been advocated by a number of electricity sector economists and commentators as ‘the right answer’, but what is the question, and is it the right answer for the challenges we face now in decarbonising and expanding the electricity system in Britain? In this extended

Locational Signals for Electricity system flexibility alongside a national wholesale market

As the dust settles on the second REMA (Review of Electricity Market Arrangements) consultation, this blog reviews the debate on locational signals, their importance for flexibility, and the need for a more concrete articulation of what could be improved alongside a national wholesale market. It feels like we have been debating the options for improving locational signals
