Link end analysis
Wind turbines are thought to interfere with microwave links in three separate ways: nearfield effects, diffraction and reflection. To avoid interference from these effects, three exclusion zones can be constructed along the path of an existing communication link. If turbines are positioned such that they do not encroach on these exclusion zones, the turbine will not affect the link.
For many sites, two dimensional analysis is sufficient to ensure that turbines do not interfere with existing links, and this is the preferred method of link operators. In reality, however, the exclusion zones are three dimensional volumes which are not fully represented on two dimensional maps. For more complicated sites, it is necessary to perform full three dimensional space analysis to confirm or prove that the turbines will not interfere with microwave links. Using approved Ofcom guidelines, TNEI has the expertise to perform three dimensional link end analysis. TNEI can produce and submit reports to mobile link operators in support of turbine applications in sites where we believe unfounded objections have been raised.
We have close ties to the telecommunications industry and can negotiate directly with operators to resolve any potential conflicts.

Site finding and appraisal
TNEI works closely with a range of parties interested in renewable energy developments to offer site finding services across the UK, including wind farm developers or owners of a land portfolio, and solar PV developers. These same skills and datasets can easily be applied to a range of other technologies.
GIS sieve analysis
Our approach is guided by our clients and their requirements, as well as the area of search to agree a number of ‘filter’ criteria, which are then applied using a GIS mapping exercise. The output of this mapping exercise will be a list and map showing areas of land that are within the set parameters.
Initial review and assessment
This phase of work can be broken down into a number of sub-phases depending on the size of the area of search and client requirements. The objective of this phase is to review or reduce further, the areas of land identified in the sieving exercise.
Wind turbine constraints in particular can be numerous, complex and ever changing, so the interpretation of such constraints can be challenging. This is where the TNEI team can make a professional assessment of the land’s potential to host a development; balancing both development risk and potential benefits to deliver an assessment that aligns with the client’s investment analysis criteria.
Detailed assessment and landowner approaches
We work closely with our clients to deliver a bespoke package of work to meet their requirements. From detailed layout creation, to landowner identification and approaches, TNEI has the relevant capabilities to provide a competitive and effective service.
