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

•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
