  2. The spatial impact of high voltage transmission lines over the European landscape Mircea ARDELEAN

  3. High Voltage Lines Corridors • What are the high voltage line corridors? • Methodology • What is their impact over the space? • Conclusions

  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

  7. High Voltage Lines Corridors • What are the high voltage line corridors? • Methodology • What is their impact over the space? • Conclusions

  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./km2 • 85% of population lives in areas with densities ≥ 300 in./km2 • = average European population density 150 in./ km2 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

  12. High Voltage Lines Corridors • What are the high voltage line corridors? • Methodology • What is their impact over the space? • Conclusions

  13. High Voltage Lines Corridors Impact • High voltage corridors: 12 000 km2 area, 240 000 km length 0,25% from total area, 5 km/100km2

  14. High Voltage Lines Corridors Impact • Corridors cost in high density areas 400 km2 area, 8800 km length 0,30% from total area 6,6 km/100km2

  15. 20 bln € 600 mln € High Voltage Lines Corridors Impact • Corridors cost in high density areas

  16. High Voltage Lines Corridors Impact • Corridors in Natura 2000 1287 km2

  17. High Voltage Lines Corridors Impact • Corridors in CLC 2006

  18. High Voltage Lines Corridors Impact – Case study: Czech Republic Area: 267 km2 Length: 5330 km Urban area: 24 km2 Urban length: 480 km

  19. High Voltage Lines Corridors Impact – Case study: Czech Republic 11x Artificial urban: 10 km2 12x-13x Artificial industrial: 3 km2 14x Artificial green: 0,5 km2 21x-24x Agricultural arable: 174 km2 31x Forests: 45 km2 32x-33x Grassland: 2 km2 4xx-5xx Wetlands&Water: 1,5 km2

  20. High Voltage Lines Corridors • What are the high voltage line corridors? • Methodology • What is their impact over the space? • Conclusions

  21. High Voltage Lines Corridors Conclusions • Affected area: 12000 km2– Size of small country • Estimated costs: • more than 20 bln euros in real estate • more than 3,5 bln euros in forests • Remedies • Underground cables • Increase line’s capacity • Distributed energy
