Can better turbines alone scale offshore wind to the pace Europe’s 2030 and 2040 climate and energy security targets require? Not on their own. However efficient a turbine becomes, its electricity is only useful if it reaches the people, industries, and public services that need it. That’s what offshore wind grid infrastructure does, and it deserves as much policy attention as turbine technology itself.
A recent example: the Bornholm Energy Island
In January 2026, at the North Sea Summit in Hamburg, Germany and Denmark concluded a bilateral cost-sharing and financing agreement for the Bornholm Energy Island. This builds on cooperation between the two countries that dates back further, including a €645.2 million Connecting Europe Facility grant agreement signed in September 2025. The January agreement establishes the financial framework needed to move the project into implementation. The European Commission has framed it as a first delivery under the Energy Highways initiative, introduced through the European Grids Package, which the Commission presented on 10 December 2025.
Denmark’s Energinet and Germany’s 50Hertz are developing the project. It will connect 3 GW of offshore wind generation capacity to the Danish and German electricity systems through a single hub on Bornholm. The European Commission describes it as the world’s first hybrid direct current interconnector. Rather than simply linking one wind farm to one national grid, a radial connection, it combines offshore generation with a cross-border electricity link between two countries in a single asset.
That combination is part of why the Commission has prioritised it as a Project of Common Interest (PCI). PCI status gives a project access to coordinated permitting and regulatory procedures. It also makes the project eligible to apply for support under the Connecting Europe Facility. Funding itself isn’t automatic; it depends on meeting the relevant conditions.
This is background context, not a LIGHTWIND initiative. We’re highlighting it because it illustrates a policy dynamic that matters for any offshore wind technology, including the kind LIGHTWIND is working on. Generation capacity and the infrastructure to carry it cannot be planned separately.
The policy challenge behind projects like this
Approving individual projects like Bornholm is only part of the task. Commission guidance published alongside the December 2025 Grids Package reported that at least 16 Member States faced grid connection queues as of mid-2025. Connection requests have been growing sharply year on year. In many markets, renewable generation and new electricity demand are progressing faster than the network connections needed to accommodate them.
Closing that gap involves questions that go beyond building more cables. Who pays for cross-border infrastructure? How are the costs split between the countries and consumers who benefit differently from it? The Grids Package proposes strengthening the use of congestion income, revenue generated from price differences between markets, for infrastructure of cross-border relevance. It also seeks to strengthen cross-border cost-and-benefit allocation, so investment responsibilities better reflect how benefits are distributed between participating and neighbouring countries. These remain legislative proposals moving through the EU process, not yet binding rules. Bornholm itself required Denmark and Germany to agree a shared cost-sharing framework before construction could proceed. That’s exactly the kind of negotiation that determines whether a hybrid project like this actually gets built, not just approved on paper.
Permitting timelines matter too. Under the existing TEN-E framework, PCI permit-granting procedures follow coordinated timelines that generally total up to 42 months. Extensions are possible in defined circumstances. The December 2025 Grids Package proposes additional measures to further accelerate permitting for grids, renewable generation, and storage. This has also increased attention on anticipatory investment: building network capacity ahead of fully confirmed demand, alongside safeguards against inefficient or stranded investment if expected projects don’t materialise.
Grid infrastructure is more than cables
It’s worth being precise about what “grid infrastructure” actually covers. The physical assets, cables, converter stations, substations, are the most visible part. But they depend on a regulatory architecture that has to work just as well: permitting rules, market arrangements for hybrid offshore assets, connection queue management, and agreed responsibilities between national regulators and transmission system operators.
There’s also a security dimension worth acknowledging. Interconnection can strengthen resilience through diversification and cross-border support. But reliance on individual high-capacity cables and converter stations can also create critical points of failure. That trade-off is part of the current policy conversation around offshore and cross-border energy infrastructure, not a side issue.
On the market side: a hybrid interconnector doesn’t simply send electricity to the country that “needs it most.” Flows depend on market coupling, available capacity, price signals, and operational security. Its value lies in allowing offshore generation and cross-border trade to use shared infrastructure more flexibly.
Turbines and grids: interdependent, not separate tracks
Turbine and drivetrain innovation, the kind of work LIGHTWIND is engaged in, focuses on generating more power more efficiently and cost-effectively, particularly for floating platforms further from shore. That’s one important part of scaling offshore wind, alongside ports, installation vessels, component manufacturing, and the grid infrastructure and market rules covered above.
Distance from shore is where the turbine and grid questions connect most directly. The farther a wind farm sits from the coast, the more expensive and technically demanding the export cables and grid connection become. That’s a large part of why floating offshore wind, which can be sited farther out and in deeper water than fixed-bottom turbines, faces a particularly demanding version of the grid infrastructure challenge.
Where LIGHTWIND fits
LIGHTWIND is developing drivetrain technology aimed at making floating offshore wind lighter and more cost-effective. Because floating wind farms can be located farther offshore, they may face more demanding and costly export-system requirements. Where several projects, countries, or offshore hubs share infrastructure, as with Bornholm, coordinated cross-border planning becomes particularly important. A lighter, more cost-effective drivetrain only creates value if the grid exists to carry what it generates.
What this means for policymakers
The lesson from Bornholm isn’t simply that grids matter, that much is already well understood. It’s that offshore wind targets, grid development plans, cost and benefit allocation between Member States, and permitting timelines need to be designed together, not sequenced one after the other. Technology programmes can improve the performance and cost of individual turbines. Coordinated infrastructure planning determines whether those improvements translate into secure, affordable electricity delivered at the scale Europe’s targets require.
