Company Profile: Solar Tower Systems GmbH Complete Solar Island Heliostat Field Receiver (direct steam and molten salt) Control System developed with Bosch Rexroth STS Technology: Savings in Heliostat Field: Up to 15% less Reflector Area Up to 50% less Ground Area STS offers License for STS-Technology Technology Transfer Services Performance estimation STS looks for local industrial partners 6

Saudi-Arabia specific characteristics of the Tower Technology Tower in general doesn t have the track record as the trough technology 1 2 Large technological innovations are more likely than in more mature technologies 8 7 6 Those innovations should be realized in smaller projects (less risk!) 4 3 4 5 Local know-how can be created in pilot projects This can be beneficial for the local industry (even as a gateway to larger projects) Capacity building an education will be an important aspect A (research) pilot plant could fulfill a variety of purposes 7

Proposal for a Joint Pilot Project A complete Solar Tower Plant that fulfills a variety of Purposes: The education of amongst others, Scientists, Students, Operational Staff, Technicians in a complete solar power plant. One or more research platforms can be included to test, validate and compare different receiver concepts for electrical or non-electrical (high temperature) applications under Saudi-Arabian conditions. Localization of research and development and creation of local know-how. 8

Proposal for a Joint Pilot Project Purposes of the heliostat field: Local Production of Heliostats: The German Companies intend to deliver Technology (e.g. Licenses) rather than hardware. The project enables Saudi suppliers to contribute to larger (commercial) projects. Testing and operation of different heliostat types under local conditions Infrastructure for measurement and qualification of heliostat suppliers for other projects (e.g. deflectometry) Development and optimization of heliostat field infrastructure (e.g. customized cabling, wireless) and other innovative technologies (e.g. automatic cleaning systems) 9

Solar Tower Technology Made in Germany Summary and take-aways Key Statements Tower will have a considerable share of the future CSP market Tower technology is less mature than trough Large innovation steps should be taken within small projects Our Proposal A pilot solar tower plant to qualify local suppliers and local knowhow Infrastructure for R&D on electrical and non-electrical applications Opportunities and benefits for Saudi partners Creation of local know-how A low risk market entry (reference and qualification) Why choosing German partners Strategy: Large local content and strong local partners High tech and high quality technology supplier 10
