DNV has been chosen by Iberdrola to perform power curve verification at the 496MW St Brieuc offshore wind farm, off the coast of Brittany, in France.
The data gathered by DNV will help Iberdrola to understand and optimise the wind farm’s performance, setting a benchmark for other future offshore wind projects.
DNV will employ nacelle lidar technology to perform the verification.
Developed by Ailes Marines, a subsidiary of Iberdrola, the 62-turbine wind farm has been fully operational since May 2024.
DNV’s power curve verification project encompasses the design, commissioning, and execution of a power performance measurement (PPM) campaign for three machines, along with the installation of all necessary equipment to ensure the campaign meets accreditation standards.
Before deployment, the lidars will be calibrated at DNV’s testing facility in Germany to comply with the updated IEC 61400-50-3:2022 standard.
This standard allows for the use of nacelle-mounted lidars (NML) in performance assessments, an area where DNV has extensive expertise.
The power curve verification will enable Iberdrola to align actual energy production with initial projections, improving the accuracy of economic models for the wind farm.
The initiative enhances operational efficiency and supports broader sustainable development goals.
“DNV is one of the pioneers in power performance measurement using nacelle lidar technology. This project showcases our ability to leverage advanced technologies and adhere to stringent industry standards in wind energy,” said DNV’s executive vice president and regional director for energy systems Santiago Blanco.
“We are dedicated to advancing safety and performance, setting industry benchmarks, and developing solutions to address the global energy transformation.”
Offshore wind resource manager at Iberdrola Jerome Dumont added: “Following the full commissioning of Saint Brieuc Offshore Wind Farm, Iberdrola/Ailes Marines is looking forward to monitoring wind conditions and performance of the asset with the help of nacelle LIDAR technology.
“We expect that the experience and expert knowledge of DNV, one of the key players in power curve testing, will allow for a successful and instructive measurement campaign, based on up-to-date standards and technology.”
