SgurrEnergy's loss tree and performance ratio assessment is a structured breakdown of every deduction applied between a renewable project's gross resource and its net energy yield, quantifying each loss category — soiling, wake, clipping, curtailment, degradation and availability — and documenting the assumptions behind it to a transparent, lender-ready bankable standard.
Why This Service Matters
SgurrEnergy develops and reviews loss trees to ensure production estimates properly reflect technical losses, availability assumptions, degradation, grid constraints and operational realities.
When This Service Is Needed
Yield assumptions require transparent loss allocation
A project has technology, site or grid conditions that affect losses
A lender requires clear explanation of production deductions
An asset owner needs to diagnose where energy is being lost
