Shell has confirmed its complete withdrawal from two major floating wind projects in Scotland as part of a strategic reassessment of its capital commitments. The company has sold its 50% stake in MarramWind to its partner ScottishPower Renewables, a subsidiary of Spanish group Iberdrola, which will now solely develop the 3 GW project. Simultaneously, Shell has returned the concession for the 2 GW CampionWind project to Crown Estate Scotland, the owner of the Scottish seabed and administrator of the ScotWind programme, which will now seek to reallocate the site.
A pivot towards fast cash-generating activities
This move reflects Shell’s intent to reduce future capital expenditure in long and complex projects in favour of more competitive segments such as liquefied natural gas (LNG), energy trading and power trading. The withdrawal also highlights structural constraints affecting the UK floating wind sector, including high installation costs, connection delays and limited visibility ahead of the next Contract for Difference (CfD) auction round scheduled for 2025.
ScottishPower consolidates MarramWind, CampionWind returns to the market
ScottishPower Renewables has confirmed it will continue developing MarramWind after taking full control of the project. Meanwhile, CampionWind has been returned to Crown Estate Scotland, which will either reallocate it to new developers or place it on hold. This development alters the composition of the ScotWind pipeline and tests the market’s capacity to meet the technical, industrial and contractual requirements of floating wind deployment.
Strengthened CfD framework, but persistent uncertainty
The UK has revised the CfD framework for upcoming auction rounds by raising Administrative Strike Prices and offering twenty-year contracts indexed to inflation (CPI). However, these adjustments still fall short of Shell’s internal investment return thresholds, especially when compared with opportunities in LNG or flexible power solutions.
Impact on the Scottish industrial supply chain
While MarramWind’s continuation provides partial support to the local supply chain, the withdrawal from CampionWind removes 2 GW of near-term volume. This reduction may delay industrial investment in floating-specific infrastructure such as hulls, dynamic cables and port facilities—elements critical to achieving cost competitiveness through scale.
Shell maintains selective capital allocation strategy
By reducing its exposure to high-intensity, long-cycle assets, Shell aligns with its announced capex range of $20bn to $22bn between 2025 and 2028. The renewables portfolio is shifting towards an “asset-light” model with greater emphasis on trading, flexibility, and retail. This approach is consistent with the group’s “value over volume” strategy, which aims to optimise returns without expanding physical energy production.
Limited market impact, but medium-term implications
As neither project had reached final investment decision (FID), the immediate impact on the UK electricity market is minimal. However, the removal of CampionWind may reduce regional supply prospects in the medium term. Key developments to monitor include Crown Estate Scotland’s decision on the site’s future, the results of AR7, and the grid connection timeline managed by Electricity System Operator (ESO).
