“Superhighway” has a powerful ring to it. It seems like a definitive answer that will put bottlenecks firmly in the rear-view mirror. Yet the UK’s new electricity superhighway, accepted by the energy regulator this week, is a extra contained endeavor.
The £3.4bn Eastern Green Link 2 does imply a big step-up in electricity transport capability. When operational in 2029, it will present 2 gigawatt of capability over 436km, from Scotland to Yorkshire, a near-30 per cent improve in contrast with peak availability throughout the border at present. It can be the first venture to obtain ultimate funding sign-off from Ofgem beneath new guidelines to speed up the supply of infrastructure.
The fly in the ointment, nevertheless, is that upgrading the UK’s electricity grid for the energy transition is such an unlimited endeavor that this enterprise barely makes a dent in it. The problem is a worldwide one. National Grid has almost doubled its funding plan to £60bn, of which just about 80 per cent will be on electricity networks. Goldman Sachs estimates that Europe alone will want virtually €800bn on transmission and distribution in the coming decade.
There are two causes. First, electricity demand will rise sharply as EVs and warmth pumps take off. And secondly, renewables generate electricity elsewhere from the previous fossil power stations.
Wind power is more and more being generated in Scotland, and — even with this piece of equipment — there’s not sufficient transport capability to ship it to areas of demand in the south of the UK. Already, peak electricity manufacturing in Scotland is maybe 10-14GW, thinks Tom Edwards from Cornwall Insight, in contrast with native peak consumption of 3GW. Scotland might add as a lot as 10GW of manufacturing capability by 2030.
Worse, transport bottlenecks are solely part of the downside. Renewables are struggling to connect with the grid, with greater than 700GW of potential capability caught in a queue, based on a June report by Octopus Energy. Efforts to handle this have not delivered a significant acceleration.
Ofgem’s fast-track course of for transport infrastructure does supply a spark of hope. National Grid’s electricity system operator has 5 tasks in the new lane, for a mixed 10GW of transport capability. And better certainty of funding permits the operator to lock in scarce provides of cables and cable-laying ships.
Yet regardless of these efforts, it’s exhausting to shake the feeling that delivering the big funding plans introduced by utilities stays staggeringly bold — as does the hope of decarbonising electricity grids any time quickly.
