A lender-ready wind resource assessment with QC, MCP long-term correction, flow modelling, gross-to-net losses, uncertainty budget, and P50/P75/P90 outputs.

How fast is the turnaround?

Typical delivery is 4 to 6 weeks depending on data quality, terrain complexity, and the number of masts or datasets in scope.

Do you work with lenders and technical advisors?

Yes. The workflow is written for project finance review by lenders and technical advisors, and the report is structured to be reviewed line by line.

Wind Resource Assessment

Bankable WRA, delivered on a lender timetable.

Independent wind resource assessments for global projects. The work is built around QC, long-term correction, flow modelling, uncertainty propagation, and IEC 61400 site suitability so the output can survive lender technical advisor review.

What it includes

MEASNET-aligned QC

Met mast or LiDAR data is cleaned before modelling. Data recovery, drift, icing, and shadow issues are documented explicitly.

Long-term correction

MCP against ERA5, MERRA-2, or local reference datasets to extend short onsite records into a defendable climate.

Flow modelling and losses

WAsP for simpler terrain, WindPRO or CFD when the site demands it, plus gross-to-net loss build-up.

Frequently asked

How do you handle sparse on-site data?

Short or gappy records are extended via MCP against ERA5 / MERRA-2 with explicit uncertainty terms. If correlation is poor, a second reference is brought in.

Will your report satisfy lender review?

Yes. Every deliverable is built to the standard lenders and technical advisors expect: independent, MEASNET-aligned QC, IEC 61400 site suitability, and defensible long-term correction.

Can you coordinate with our technical advisor?

Yes. Methodology memos and data archives are shared on request, and defence calls are included in the standard scope.
