Tenders Are Invited For Research Services – Research Wire Casualties And Effectiveness Hawk Eye Wire Markings Vierverlaten Ens 380 Kv Connection

Research Services – Research Wire Casualties And Effectiveness Hawk Eye Wire Markings Vierverlaten Ens 380 Kv Connection. For The Vierverlaten-Ens 380 Kv Connection Project (Vvl-Ens380), Research Must Be Carried Out Into The Effectiveness Of Hawk Eye (New Form Of Wire Marking, See This Link To Article On Tennet Website) And Updating Key Figures For Wire Casualties Per Type. Both Are Necessary For The Permit Granting Of The Project, But Must Also Be Applicable Across Tennet For Other Line Projects. Research Data From 1987 Is Currently Used To Determine The Number Of Wire Casualties Under High-Voltage Connections. These Data No Longer Correspond To The Current Situation And Do Not Provide An Adequate Basis To Carefully Substantiate The Ecological Impact Of High-Voltage Infrastructure. This Creates Uncertainty About The Extent Of The Effects On Bird Populations And About The Effectiveness Of Any Mitigation Measures. The Intended Research Therefore Has Two Related Objectives. First Of All, A Current Baseline Measurement Is Carried Out To Gain Insight Into The Number Of Wire Casualties Under And In The Immediate Vicinity Of The Existing 220 Kv High-Voltage Connection Between Vierverlaten And Ens. The Effectiveness Of Mitigation Measures Is Then Examined By Applying Them To Selected Masts And Conductors And Monitoring The Results. An Important Part Of The Research Concerns The Assessment Of The Effectiveness Of Different Types Of Bird Markings. Within The Organization There Is A Preference For The Use Of The Hawk Eye Wire Marking As A Mitigating Measure. However, There Is Currently No Scientific Substantiation Of Its Effectiveness Under Dutch Conditions For Broader Implementation. The Research Must Therefore Provide The Knowledge Base Necessary To Make Well-Founded Choices About The Use Of This Measure And To Demonstrate Its Contribution To Reducing Wire Casualties.
