Vattenfall optimises offshore wind farm layouts over a 25-year horizon with AI-assisted engineering tools
The AI tools optimise turbine placement, cable routing, and installation sequence, maximising net present value over the full lifecycle of a wind park, accounting for wind data, seabed conditions, inter-turbine interference, and regulation.
Friction
Offshore wind farm design is an enormously complex optimisation problem. Suboptimal choices made in the design phase lock in losses over a 25-year operational lifetime. Traditional engineering approaches could not explore enough design variants to find the true optimum.
Breakthrough
Developed with scientists from DTU Denmark and Bologna University, the tools use Mathematical Optimisation combined with heuristic AI to model wind patterns, seabed topology, and shadow effects between turbines. NPV optimisation runs over the full 25+ year lifetime. Results are peer-reviewed.
Impact
€150M+ NPV gain on already-acquired wind farm sites, peer-reviewed. Tools contributed to competitive bids on subsidy-free offshore wind farms. Vattenfall's wind capacity grew 34% in 2024 through commissioning of new parks. Design process significantly accelerated.

Problem
Offshore wind development requires enormous capital investment over a 25+ year horizon. Mistakes made in the design phase cannot be undone. Yet traditional engineering tools could not explore the full solution space.
What made it smart
Optimising for NPV over the full lifetime, rather than for a proxy metric like power output, is the key insight. It forces the model to account for all cost drivers simultaneously: not just wind yield, but installation costs, cable length, seabed complexity, and regulatory constraints.
Technical approach
Mixed-Integer Linear Programming models wind patterns, seabed, and wake effects between turbines. AI heuristics extend the solution search space beyond what pure MILP can handle at speed. Engineers use the tools for decision support during tender preparation.
Strategic lesson
The highest-value AI in capital-intensive industries sits at the design and investment decision stage, where every optimisation compounds over decades, not quarters.
Reflection question
Where in your organisation are major investment decisions made that will lock in costs or capabilities for 10, 20, or 25 years, and how much of that decision is currently based on exploring the full solution space?
