Compare measured height assumptions and actual curve energy, obtain complete tower and foundation design, and retain receptor and installed-scope evidence.
Record candidate tower locations, obstacles, property boundaries, access and maintenance space. Obtain actual height, setback, aviation and other site requirements from the relevant project process. Keep the turbine rotor envelope and the tower’s structural and working areas distinguishable on the plan.
Collect wind observations with sensor heights, exposure, averaging periods and calibration/quality notes. Derive a measured shear exponent only from comparable paired-height observations, or state the assumptions of a neutral log profile. Preserve directional and seasonal differences that a single exponent can hide.
Use one turbine curve, one resource period and one loss convention for the height comparison. Adjust each reference speed bin with the stated shear assumption and inspect electrical energy at both heights, including cut-out periods. Compare the extra yield with uncertainty rather than assuming a fixed tower benefit.
Obtain the exact tower/turbine load combinations and soil investigation for each feasible height. The structural team must resolve foundation geometry, reinforcement, anchors, settlement and dynamic/fatigue behavior. Screen actual rectangular gravity-footing candidates only within their stated full-contact static scope.
Review sound at the actual receptors with compatible source data and the applicable assessment method. Compare complete tower, foundation, lifting, route and connection quotes and their service implications. Keep resource benefit, project cost and practical maintenance access together in the decision.
Record the chosen height, resource assumptions, accepted design documents, scope exclusions and approval conditions. Retain the surveyed as-built hub position and commissioning baseline. Compare later observed energy and wind records with the same height and meter basis before attributing a difference to tower performance.
Describe rotor-envelope geometry with entered project clearances.
Compare whole-turbine fit in explicit rectangular grid families when an array is proposed.
Check paired-height shear or the valid roughness/displacement domain of a neutral log profile. · Keep any revised height adjustment tied to comparable observations.
Retain the direction-duration context for candidate locations.
Calculate same-curve energy differences for two heights, including zero or negative change.
Inspect particular curve points when a height change crosses an operating threshold.
Retain static candidate pressures and explicit failed comparisons for the supplied load case.
Document measured gust/mean durations without inferring an extreme design class.
Check the stated free-field pressure/power reference and combine compatible receptor levels.
Compare complete actual connection quote boundaries.
Value the incremental delivered energy and dated tower-related costs.
Reconcile actual period energy after commissioning.

Height adjustment and power-curve energy belong to one documented resource model.
Static bearing and stability checks require consistent loads and contact assumptions.
Sound pressure and sound power require different distance-model inputs.
A simple profile can help compare assumptions without resolving complex terrain or turbulent flow.
Extra energy has to be considered with foundations, installation, access and long-term service.
