SgurrEnergy's long-term data correlation and uncertainty analysis adjusts short-term on-site measurements against long-term reference datasets, producing a long-term corrected, bankable resource estimate for a renewable energy project. It gives yield and revenue assumptions a defensible long-term basis rather than one limited to the on-site measurement period, strengthening confidence for financing and transactions.
Why This Service Matters
SgurrEnergy correlates measured or modelled resource data with long-term reference datasets to reduce uncertainty and strengthen yield assumptions used in investment and financing decisions.
When This Service Is Needed

On-site measurement duration is limited
Long-term variability may affect project revenue assumptions
A lender requests defensible long-term correction methodology
A transaction requires validation of historic resource assumptions
