Continuing its reputation for technical excellence, Natural Power landed a top five score in an independent Energy Yield Analysis blind test against sixty teams from 56 participants including most major consultancies.
Natural Power's assessment of the yield of an operational wind farm, based on the provided pre-construction data, varied from the actual metered production by just 0.07%.
The Comparative Resource Energy Yield Assessment Procedures (CREYAP) exercise, managed by renewable energy developer RES together with DTU, was part of a practical session at the European Wind Energy Association (EWEA) Resource Assessment Workshop in Dublin earlier this year.
The result confirms Natural Power's position as a provider of first-class finance-grade energy yield analysis services for wind farm lenders, investors and developers, and demonstrates our continued commitment to the application of cutting edge best practice in the field of wind farm resource assessment.
Utilising over two decades of practical consulting experience, the technical team started by using the five years of data from the primary 50m mast as the long-term dataset. They also employed the company's Computational Fluid Dynamics (CFD) methodology (based on VENTOS®) to analyse the data provided to them to carry out the energy yield assessment.
Oisin Brady, Director of French operations at Natural Power, also chaired a session on Wind Conditions Modelling at the workshop. The session discussed the complexities of new sites, the ever-increasing demands placed by operators and financiers, and how these issues are being addressed through significant progress in weather modelling, computational power and a merger of meteorological and engineering approaches to modelling.
With almost 20 years of practical experience in wind energy consultancy and an international reputation for technical excellence and innovation, Natural Power's technical team have worked on over 40 GW for their clients.
