4. High Voltage Lines Corridors What are the high voltage line corridors?

5. High Voltage Lines Corridors What are the high voltage line corridors? 20-80 m Right of Way (ROW)

6. High Voltage Lines Corridors What are the high voltage line corridors? Right of Way – differs from country to country 20-25 m …………. Below 110kV 35-40 m …………. 110kV 50-60 m …………. 220kV 70-80 m …………. 400kV 80-90 m …………. 750kV Importance: Access for maintenance Protection from accidents Restrictions on building and activities Act as selective and partial barrier Impact over the economy of the crossed spaces Disrupt the space

8. High Voltage Lines Corridors Methodology Source of data PLATTS electrical transmission dataset European Population Grid GESTAT Corine Land Cover 2006 Natura 2000 Soil Atlas …other datasets Reliability

9. High Voltage Lines Corridors Methodology – the work flow

10. High Voltage Lines Corridors Methodology High population density areas Above 300 in./km 2 85% of population lives in areas with densities ≥ 300 in./km 2 = average European population density 150 in./ km 2 X 2

11. High Voltage Lines Corridors Methodology Cost estimation 3% lower real estate price neighboring an electric line (McNair & Abelson, 2010) Land below an electric line is lost for real estate land price = 50 euro /sqm as European average
