How can the local added value be increased? Capacity Building

Desertec concept

Solar electricity production in North Africa

Production for increasing local demand

Later additional transport to Europe

Approx. 600 GW CSP installed until 2050

Equivalent to 250 Andasol plants per year

Requires a substantial contribution of the African countries

The African countries have to be enabled to contribute to the planning, erection and operation of solar thermal power plants

Summary

Solar thermal power plants are a proven technology for solar electricity generation at utility scale.

At present numerous projects are realised world-wide

Solar thermal power plants feature a fair balance between national and international added value

The Desertec concept offers an ambitious vision for the implementation of renewable energies in North-Africa

The realisation of Desertec demands a substantial contribution of the North-African countries

This contribution can only be achieved by an appropriate Capacity Building
