TEP assisted the Manx Electricity Authority in identifying potential windfarm sites which met key requirements of good exposure to wind; accessibility by road for transportation of equipment; and locations that could link into the existing electricity system.
Sites that met the basic requirements were appraised in relation to strategic development constraints. These constraints included: designated sites of nature conservation value; areas of high landscape value; aircraft flight zones; areas of land subject to contamination or subsidence; land allocated for development and proximity to housing.
The most preferred sites were then subject to further detailed assessment allowing the feasibility of wind power development on the island to be examined further in subsequent phases of work.
