A meaningful comparison.
A Danish wind farm may generate more than a Spanish one without performing better. Compare actual delivery with a modelled expectation for the conditions and equipment at each site.
- Establish the baseline.Resource conditions, equipment and comparable periods.
- Find the deviation.Delivered energy against expected output, with uncertainty.
- Investigate the cause.Availability, losses, curtailment and operating evidence.
ERA5 and other resource inputs inform the baseline. Weather reanalysis alone cannot establish an equipment fault or a grid restriction. Diagnosis needs operating evidence.
