Ofgem OKs Transmission Investments Needed For UK’s 2030 Offshore Wind Target

The title of this post, is the same as that, of this article on offshoreWIND.biz.

This is the sub-heading.

Ofgem has approved the strategic electricity transmission reinforcements required to deliver the UK Government’s 50 GW offshore wind by 2030 target, set out as part of the regulator’s Accelerated Strategic Transmission Investment (ASTI) framework.

A map then shows the principle new transmission reinforcements.

These include two 2 GW subsea HVDC links from Peterhead to England, both of which will be taken forward as joint ventures with National Grid Electricity Transmission (NGET), a 2 GW subsea HVDC link from Spittal in Caithness, connecting to Peterhead, as well as a 1.8 GW subsea HVDC link from Arnish on the Western Isles to the Beauly area near Inverness.

The approval also implies 400 kV onshore reinforcements, between Beauly, Blackhillock, New Deer and Peterhead; between Beauly, Loch Buidhe and Spittal; and between Kintore, Tealing and Westfield; and uprating the existing Beauly to Denny line to enable 400 kV operation on both circuits.

All cables seem to lead to Peterhead.

  1. They don’t say whether this is sufficient to remove all teh constraints on teh system. ESO have shelled out over £200m this year so far in forcing wind operators off the system largely in Scotland due to inadequate transmission and this with an installed capacity nearly 20GW than teh 2030 target. The build out of wind needs to go hand in hand with transmission expansion but can’t help feeling that transmission is always playing catchup.

    • I do wonder, if one thing that needs to be done, is putting energy storage at the nodes. Starting with Peterhead.
