Hitachi Energy has warned that the UK’s slow grid expansion is inflating energy system costs and threatening net zero progress.
A new report by Aurora Energy Research shows Great Britain now has the fifth highest curtailment costs in Europe, contributing to a €8.9 billion total in 2024.
Curtailment costs across Europe have risen 27% in four years and modelling suggests Great Britain’s bill will double by 2030. This is driven by rapid growth in variable renewables contrasted with sluggish grid buildout.
The report also shows Great Britain has the longest grid connection queue in Europe relative to peak demand. The queue represents around 6.7 times annual peak demand, signalling that the country is underprepared for electrification.
Hitachi Energy is calling for urgent action to accelerate grid development. The company argues for technical innovation, standardisation and streamlined permitting to unlock capacity faster.
It also highlights Dogger Bank Wind Farm as an example where integrated planning has delivered up to £4.3 billion in consumer savings.
The EU Grids Package, due on 10 December, is expected to lay out a major upgrade plan for Europe’s electricity networks. Hitachi Energy says it represents a critical opportunity that should not be missed.
Aurora’s data shows congestion volumes rising sharply in several countries and over 800 GW of solar and wind projects seeking grid access in major European markets. Europe will need 465,000 km of new transmission lines and 6.3 million km of distribution lines by 2045.
