| Executive Summary |
Short covering letter / preliminary-result summary. |
Project and result summary tables. |
Planned
Single summary of configuration, wind resource, AEP chain, losses, P-values and key limitations.
|
| Project / site description |
Maps for two layout variants. |
Detailed site description, maps and photographs. |
Partial
Calculation site and layout exist; formal project/site passport is planned.
|
| Wind-data source / period |
Long-term-corrected measurements are mentioned; detailed procedure is not shown in the supplied PDF. |
Mast / Vortex LES / long-term data are described. |
Implemented
ERA5 multi-year hourly data and calibrated-resource lineage are recorded. Formal source/period/height passport will be expanded in reports.
|
| Measurement QA / QC |
Not disclosed in the supplied preliminary report. |
Coverage and a 75° direction correction are described. |
Planned
To be added when mast/LiDAR measurements are ingested: gaps, filtering, sensor/mast effects and calibration history.
|
| Long-term adjustment / MCP |
Long-term correction is mentioned; diagnostics are not disclosed. |
Method is described and R² is reported. |
Partial
Current calibrated ERA5 workflow and long-term statistics are implemented; it is not labelled measurement-based MCP. WindKit/brightwind are future options when site measurements exist.
|
| Vertical extrapolation |
Method details are not shown. |
Shear exponent / vertical profile and hub-height wind are reported. |
Implemented
Explicit power-law hub-height conversion with automatic ERA5 10/100 m alpha, local two-point option and manual sensitivity alpha.
|
| Air density |
Reported per WTG. |
Methodology and values are included. |
Partial
Turbine presets retain reference air density; explicit site-density correction and report treatment remain to be completed.
|
| Elevation / DEM source |
FITNAH 3D is identified as the terrain-flow method; the exact elevation-data source is not separated in the supplied summary. |
Topography / roughness are documented for WAsP CFD. |
Implemented
Copernicus GLO-30 via OpenTopography, uploaded GeoTIFF and synthetic flat DEM are supported. Dataset provenance is being standardized.
|
| Surface roughness / land cover |
Not separated from the terrain-flow description in the supplied preliminary report. |
Topography and roughness are documented for the WAsP CFD workflow. |
Planned
Add a roughness layer independent of DEM: land-cover source, z0 conversion table, optional displacement height and sector/local provenance. ESA WorldCover / CORINE are candidate free sources.
|
| Wind-climate representation |
The supplied preliminary report does not expose the complete internal representation. |
Sector/statistical wind-climate treatment is used in the consultant workflow. |
Partial
Primary engine remains chronological hourly time series. Add parallel sector-wise wind rose / Weibull diagnostics so statistical and hourly representations are explicit and comparable.
|
| Atmospheric profile: shear / veer / stability |
Not fully disclosed in the supplied preliminary report. |
Vertical profile / shear treatment is described. |
Partial
Power-law shear is implemented. Directional veer and atmospheric-stability treatment are future extensions with explicit uncertainty when not available.
|
| Ambient turbulence / TI |
Not fully exposed in the supplied preliminary report. |
Turbulence/site-flow assumptions are part of the consultant methodology. |
Partial
PyWake currently uses an explicit ambient TI assumption. Add TI provenance, directional TI handling, report output and later measurement-based TI when mast/LiDAR data exist.
|
| Background terrain-flow field before wakes |
FITNAH 3D. |
WAsP CFD / speed-up. |
Validation pending

|
| Layout / WTG coordinates |
Two variants are shown. |
Map and coordinates are provided. |
Implemented
Dedicated Layout / Siting stage is implemented before terrain flow: manual/uploaded coordinates or generated layouts, wind-rose / energy-rose orientation, fast PyWake wake-AEP screening, immutable layout export and terrain target envelope.
|
| Turbine definition / Power & Ct |
Models and source-document references are provided. |
Characteristics and curve graphics are provided; the supplied report contains some inconsistencies. |
Implemented
Stored power/Ct curves and turbine metadata are used by the calculation. Report provenance/revision controls will be expanded.
|
| Wake model |
windPRO is named; the exact wake model is not disclosed in the supplied PDF. |
N. O. Jensen. |
Implemented

|
| Wake-model configuration passport |
Not fully disclosed in the supplied preliminary report. |
Wake-model settings are partially documented. |
Partial
Standardize deficit model, superposition, rotor averaging, wake-expansion formulation, ambient TI, turbulence model and deflection settings in every run/export.
|
| Flow-model validation / benchmark cases |
Consultant model validation is outside the scope of the supplied preliminary report. |
Consultant methodology cites its selected flow model; benchmark detail is not the focus of the supplied report. |
Validation pending
Validation chain: Bypass → WindNinja COM flat DEM → WindNinja COM real terrain → NinjaFOAM/OpenFOAM RANS cross-check → external/GWA relative cross-check. Add published benchmark cases where practical.
|
| Per-WTG results |
Wind speed, density, park efficiency, AEP after wakes and net values. |
Wind speed, density, gross, after-wake AEP and sensitivities. |
Partial

| P75 / P90 / P95 |
P50/P75/P90 are presented. |
P50/P75/P84/P90/P95 are presented. |
Planned

|
| P-value horizon |
Not clearly separated in the supplied preliminary report. |
1 / 5 / 10 / 20-year horizons are shown. |
Planned
