CSP Market Shares and Development

Parabolic Trough today over 90% market share, today

Other CSP Technologies gaining market shares 20 GW installed CSP capacity by 2020 is feasible

BUT: Reliable financial and political framework needed !

Conclusion CSP Components Production in MENA

Near-term: Low-Investment and Low-Complexity Activities in MENA:

Collector Assembly

Collector Installations

Civil: Groundworks, Collector Foundations, Buildings, Infrastructure

MENA manufactoring of approximately 17% of plant invest(+ optional EPC, Proj. Management)

If sustainable MENA-CSP-Markets are given:

More investment-intensive and more complex CSP-Activities in MENA:

Mirror Production

Receiver Production

Other specialized components and processes

Local Value Creation: up to 80% of plant invest
