Quantrex digital platform operational across portfolio

The rollout of Quantrex's proprietary digital twin platform is now complete across all offshore wind assets. Real time data from more than 800 turbines flows continuously into AI models that predict performance optimize output and schedule maintenance before failures occur. Early results show a 12% reduction in unplanned downtime across the offshore portfolio.
Every offshore wind turbine in the Quantrex portfolio is now connected to the company's proprietary digital twin platform. The rollout which began in 2023 with a pilot across twelve turbines at Nordvik Array has been completed ahead of schedule with all 847 offshore turbines now fully integrated.
Digital twin
A digital twin is a continuously updated virtual model of a physical asset. Every Quantrex turbine is equipped with more than 400 sensors monitoring rotor speed blade pitch nacelle temperature gearbox vibration generator output and dozens of other parameters. Data from those sensors flows in real time to the digital twin platform where AI models compare actual performance against the predicted performance of a perfect twin operating under the same conditions.
Deviations from expected performance trigger alerts that are reviewed by the operations team and in many cases result in maintenance interventions that prevent failures before they occur.
Turbines connected
The early results are striking. In the six months since the final turbines were connected to the platform the offshore portfolio has recorded a 12% reduction in unplanned downtime compared to the equivalent period in the previous year. Three major gearbox failures were predicted and prevented through early intervention.
Blade erosion was identified on fourteen turbines at a stage where repair is straightforward and inexpensive rather than requiring full blade replacement. And average turbine availability across the offshore portfolio has risen from 94.2% to 96.8%.
Performance benefits
The platform also delivers performance optimization benefits beyond fault detection. AI models continuously adjust blade pitch and yaw settings on every turbine to maximize energy capture given the real time wind conditions at each location. The optimization runs every thirty seconds and has delivered an average output improvement of 3.8% across the offshore portfolio compared to the previous control system.
At portfolio scale that improvement is equivalent to commissioning an additional 340 MW of generating capacity without building a single new turbine.
The next phase
Dr Sato described the platform as the most important operational capability Quantrex has ever built. We have fundamentally changed what it means to operate an offshore wind farm. We are no longer waiting for things to go wrong and then fixing them. We are predicting what will go wrong weeks in advance and preventing it. That shift has real consequences for output revenues and the long term economics of every asset we operate.
The next phase of the platform rollout will extend digital twin connectivity to the onshore wind and solar portfolios. Work on onshore integration is already underway with completion expected by the end of 2026.
