Is the highest point on a property always the best wind turbine location?

The short answer

No. Elevation can improve exposure in some circumstances, but terrain can also create complex flow, turbulence and difficult access. Compare the actual candidate rotor locations across the wind directions that matter to the site. A hilltop symbol on a map is not a complete wind assessment, and a lower but well-exposed position can remain a credible option.

Height above sea level is not the whole exposure story

Distinguish the land’s elevation from the rotor’s height above local ground and its position relative to terrain and obstacles. A sharp change in terrain is not equivalent to open, gently varying ground. Flow behaviour depends on the geometry and incoming wind direction.

For example, a ridge position could be exposed in one sector yet have complicated flow in another. If the important energy-bearing winds come from the second sector, judging the location from its appearance on a calm site visit could be misleading.

Compare the alternatives on common terms

Question	Ridge or highest point	Lower exposed position
Wind evidence	Assess the relevant terrain and sectors.	Assess the actual local exposure.
Construction	Check access and working areas.	Use the same construction scope.
Net project result	Include site-specific uncertainty and cost.	Include the same boundaries.

Do not fill missing wind evidence with an assumed universal ridge speed-up factor.

Let the assessment refine the shortlist

Provide the assessor with terrain information and more than one feasible position. A useful recommendation explains the preferred point, the tower-height assumption and the limitations of the evidence. Installation feasibility should remain part of the decision rather than a separate afterthought.

This approach can also prevent paying for a higher-energy location that cannot be serviced economically. MARSTON model selection should use the resulting site assumptions; the turbine rating does not resolve the terrain question by itself.
