Onderzoek Draadslachtoffers en Effectiviteit Hawk Eye-draadmarkeringen Verbinding Vierverlaten Ens 380 kV

TENDER DESCRIPTION

For the project Vierverlaten–Ens 380 kV connection (VVL-ENS380), research must be carried out into the effectiveness of Hawk Eye (a new form of wire marking, see this link to an article on the TenneT website) and the updating of key figures on bird collision victims per species. Both are required for the permitting of the project, but must also be applicable TenneT-wide for other line projects. At present, research data from 1987 is being used to determine the number of wire collision victims under high-voltage power lines. These data no longer match the current situation and provide an insufficient basis for carefully substantiating the ecological impact of high-voltage infrastructure. This creates uncertainty about the magnitude of the effects on bird populations and about the effectiveness of any mitigation measures. The intended research therefore has two interrelated objectives. First, an up-to-date baseline measurement will be carried out to gain insight into the number of bird collision victims under and in the direct vicinity of the existing 220 kV high-voltage connection between Vierverlaten and Ens. Next, the effectiveness of mitigation measures will be investigated…
