Eoltech wins repeat contracts to monitor 24 Wind Projects with IREC-index

Eoltech announced that it won repeat contracts from major French customers to monitor 24 wind farms in France, representing a total output of 500MW by deploying IREC-Index. IREC-Index will enable Eoltech’s clients to check the consistency of their fleet’s output against the available wind resource to detect potential turbine performance discrepancies.

The specificity of IREC-Index is to be based on the selection and combination of several data sources that are both independent and coherent with one another. For each region, IREC-Index takes into account at least four distinct and independent sources of wind data, whose consistency in time is checked each month. These data are then converted into production and combined to obtain robust output reference indicators by region, providing valuable information to operators wishing to optimise the energy performance of their wind portfolio.

Eoltech CEO, Habib Leseney said that most players involved in the monitoring of the power output of wind farms are looking for databases providing high correlation levels with their production data. But even if this condition is important, it is not a guarantee of reliability, because consistency in time is generally not taken into account. By combining several independent sources, the IREC Index approach can filter out inconsistent sources and increase the robustness of the results while ensuring that a high correlation level with production data is maintained.
