EU and North Sea states push offshore wind expansion as fishing industry warns of exclusion, environmental harm and ignored consultation concerns
Hamburg Declaration advances offshore wind without fishing consultation
EU governments and their North Sea partners have agreed a major expansion of offshore wind infrastructure, pledging to deliver more than 100GW of jointly developed capacity, without any formal consultation with the fishing industry or assessment of cumulative impacts on fishing activity.
Energy ministers from Belgium, Denmark, France, Germany, Iceland, Ireland, Luxembourg, the Netherlands, Norway and the United Kingdom signed the Hamburg Declaration at the North Sea Summit, committing to a regional approach that aims to transform the North Seas into Europe’s “green power plant” by 2050.
The declaration builds on earlier political commitments to install up to 300GW of offshore wind in the region by mid-century and sets out a framework for cross-border wind farms, shared grid infrastructure and joint financing mechanisms.
Offshore TSO Collaboration outlines scale of build-out
Alongside the political agreement, the Offshore TSO Collaboration has published recommendations for the coordinated roll-out of more than 100GW of new offshore wind capacity over the next two and a half decades.
According to the collaboration, comprehensive regional planning and cost sharing could allow North Sea renewables to meet around 40 percent of Europe’s energy demand by 2050. The OTC argues that coordinated development would reduce costs, improve efficiency and create a more resilient European energy system.
A central feature of the proposal is the prioritisation of offshore wind projects linked to multiple countries, combined with accelerated completion of national grid connections. The OTC also proposes a hybrid financing model, with cost allocations agreed before projects begin and adjusted later based on realised benefits.
A regional grid map published by the collaboration identifies specific cross-border projects in the North Sea, Irish Sea and Celtic Sea, areas that also support some of Europe’s most productive fishing grounds.
Fishing industry absent from decision-making
Despite the scale of the proposed build-out, there is no reference in the declaration or OTC recommendations to consultation with the fishing industry, displacement of fishing activity, or the cumulative spatial pressure created by offshore wind farms, interconnectors and associated exclusion zones.
Fishing organisations have warned for several years that offshore energy planning is proceeding without serious consideration of long-term impacts on fishing access, stock distribution and fleet viability.
EMK Fishermen criticised the political direction of travel, stating: “They know that offshore wind farms are inefficient and prohibitively expensive, require far too much maintenance, and need to be replaced after 10–15 years. They also know that wind farms harm the marine environment and kill whales and birds. Yet Europe blindly continues with them. At your and our expense.”
Ministers emphasise energy security and regional cooperation
Irish Minister for Climate, Energy and the Environment Darragh O’Brien described the summit as a turning point in regional cooperation, saying that “today’s event underscored the importance of regional cooperation to develop offshore wind capacity in the North Seas region”.
He highlighted Ireland’s offshore wind targets of 5GW in construction by 2030 and 37GW by 2050, pointing to a recent auction that secured 900MW of capacity.
UK Energy Secretary Ed Miliband framed the Hamburg Declaration as a response to geopolitical instability, stating that the agreement would deliver energy sovereignty and reduce dependence on fossil fuels. He said North Sea countries had now agreed, for the first time, to deliver 100GW of offshore wind through joint projects, including offshore hybrid assets connected to multiple countries.
Industry backing focuses on infrastructure, not coexistence
Energy network operators and renewable industry bodies welcomed the declaration, focusing on grid integration, investment certainty and market alignment.
Statements from National Grid Ventures, Energy UK, RenewableUK and Offshore Energies UK highlighted efficiency gains, job creation and energy security. None addressed the loss of fishing grounds or the interaction between offshore wind expansion and fishing activity.
Growing pressure in crowded seas
While the Hamburg Declaration commits signatories to closer cooperation on infrastructure protection and financing, it leaves unresolved how fishing, offshore energy and environmental protection will coexist as marine space becomes increasingly constrained.
For fishermen, the concern is not a single project but the cumulative effect of regional planning decisions taken without their involvement. As offshore wind ambitions accelerate, the absence of the fishing industry from strategic decision-making risks hardening opposition and deepening conflict at sea.
