What are the high voltage line corridors?
20-80 m
Right of Way (ROW)
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

•Conclusions
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
High Voltage Lines Corridors
Methodology – the work flow
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
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
