3E joins Measnet: what it means for bankable wind assessments
3E is now a member of Measnet, International Network of Wind Energy Measurement Institutes, in the Site Assessment competence area. The membership confirms that 3E’s wind measurement and energy yield assessment work meets the quality standard Measnet stands for.
For developers, investors and lenders, it provides independent recognition of the quality of the wind measurements and energy yield assessments. The key first steps for any wind energy projects.
What is Measnet?
Measnet, International Network of Wind Energy Measurements Institutes, is a non-profit founded in 1997. It brings together technical experts from across the renewable energy industry to share knowledge regardless of competition and strengthen quality standards worldwide.
The Measnet Stamp is a globally recognised quality mark, valued in international tenders and trusted to enhance project bankability.
Its more than 30 members are independent testing and technical service providers for the renewable energy industry from around the world, accredited to ISO/IEC 17025 and/or IECRE members.
Since 2015, Measnet collaborates with IECRE as exclusive Proficiency Tests provider for the wind sector in accordance with its regulations. In addition, the A-Liaison signed with the IEC TC 88 group in 2019 allows the organisation to promote technology transfer and speed up the development of technical guidelines on wind measurements.
How does Measnet membership benefit wind project developers and investors?
The main value for clients is lower assessor risk of wind measurements and energy yield assessments. Every wind project carries physical uncertainty: the wind climate varies, and no membership changes that. What Measnet membership provides is confidence that results are based on harmonized methodologies and consistent technical practices, ensuring the highest level of quality and reliability across all Measnet members, in line with the most demanding international industry standards. For lenders, that means fewer surprises, and for developers, a smoother path to financing.
Banks and investors need more than a yield figure: they need confidence that it would stand up to scrutiny. That confidence is what Measnet is built on. We can’t remove the uncertainty, but we can make sure our assessments follow industry best practices and regularly undergo evaluations through proficiency testing against other laboratories. Joining Measnet is an exciting step for 3E, and we are looking forward to a seat at the table where the next generation of standards are shaped. — Arthur Ostyn, Head of the Measurement Lab, 3E
We are very pleased to welcome 3E as Measnet's first member in Belgium. This is an important milestone for our association and a reflection of the continued growth of our international network. We are convinced that 3E's expertise and long-standing experience will provide significant benefits to the entire Measnet community and further strengthen our shared commitment to quality and excellence. — Monika Krämer, Measnet Chairwoman
How is Measnet membership linked to ISO/IEC 17025 and FGW TR6?
ISO/IEC 17025 accreditation is a prerequisite for Measnet membership. It is the international standard for the competence of testing and calibration laboratories. Since 2025, the 3E Measurement Lab at our Brussels headquarters has been accredited to ISO/IEC 17025 by BELAC (772-TEST) for wind measurement campaigns according to IEC 61400-50-1 and -2, and for energy yield assessments following the Measnet procedure for the evaluation of site-specific wind conditions and FGW TR6.
FAQ
- What does Measnet stand for? Measnet stands for Measuring Network of Wind Energy Institutes. It is an international non-profit network of organisations that perform wind energy measurements and assessments.
- Does Measnet membership reduce wind resource uncertainty? No. The physical uncertainty of the wind climate stays the same. Measnet membership reduces assessor risk: the risk that an energy yield estimate depends on which consultant produced it.
- Do you need ISO/IEC 17025 accreditation to join Measnet? Yes. ISO/IEC 17025 accreditation is a mandatory prerequisite for Measnet membership. 3E’s Measurement Lab has held this accreditation since 2025.
