The UK's offshore wind sector requires urgent government action to restore investor confidence and meet 2030 decarbonisation goals, industry leaders warned at the All-Energy conference in Glasgow on 14 May.
Speaking at the panel Offshore Wind 2024: A Year in Turmoil, experts called for policy stability, streamlined consenting and stronger supply chains to unlock the sector's potential.
Chair of industry body Global Wind Energy Council (GWEC) Jonathan Cole criticised the government's proposed locational marginal pricing reforms, arguing they introduce complexity and deter long-term investment. "We're not building coffee shops and bookstores, we're building infrastructure that will sit in one location for generations," he said. Cole warned that a 1pc rise in capital costs could erase £20bn in projected benefits, urging policymakers to prioritise stability over "speculative" market changes.
ScottishPower Renewables' chief executive, Charlie Jordan, echoed the need for clarity, highlighting the £75bn investment in UK grid upgrades, particularly in Scotland, as critical for jobs and future-proofing the energy system. He said the ongoing review of electricity market arrangements (Rema) risks undermining grid investment and called for practical measures like general taxation to protect consumers from rising transmission costs.
Both panellists stressed the need to accelerate consenting processes to maintain project timelines. They also emphasised strengthening the UK's offshore wind supply chain to compete with nations like South Korea and France. "Without swift action on ports, manufacturing and grid connections, we'll lose opportunities," Jordan said, pointing to Scotland's ScotWind seabed leasing programme and Celtic Sea offshore wind projects.
Scotland has 3GW of offshore wind capacity across seven wind farms, including the 1.1GW Seagreen and 30MW Hywind Scotland. Projects under construction, such as the 450MW Neart na Gaoithe and 882MW Moray West, bring the nation's pipeline to 10.2GW expected by 2030, aligning with the Scottish government's 11GW target. The ScotWind seabed leasing round saw 25GW of leasing options agreements awarded in January 2022, with projects like the 2.1GW Berwick Bank, 1.1GW Inch Cape and 560MW Green Volt in planning. But recent setbacks have raised concerns about deliverability.
The cancellation of Danish utility Orsted's 2.4GW Hornsea 4 project in May, despite a 15-year contracts for difference (CfD) at £83/MWh, underscores the sector's challenges. Orsted cited rising costs and "execution risks" from installing 180 turbines, highlighting economic unviability under current conditions.
Transparency in energy pricing was deemed essential for public support. Jordan said prohibitive costs, driven by taxes and seabed leasing fees, make UK industrial users 70pc less competitive than their European counterparts. Cole added that clear communication is vital as discussions about market reforms and potential EU alignment intensify.
With the upcoming seventh round of the CfD scheme and ongoing government consultations, the panel urged decisive action to stabilise the sector. "This is the time for long-term vision, not academic experiments," Cole said.
