NTR – Track Record of Success
Formed in 1999 in Phoenix, SES acquires dish system technology previously developed by McDonnell Douglas, Southern California Edison, the Dept. of Energy and Sandia National Laboratories
Focus on developing and commercialising the SunCatcher technology for solar thermal applications
Signs Power Purchase Agreements with each of San Diego Gas & Electric (750 MW) and Southern California Edison (850MW)
May ‘08 - NTR plc (renewable energy operator and developer) completes a $100m investment in May to take a controlling interest in SES (followed by a further $55m in November 2009)
• Integration well underway -headcount triples in first six months
• Hire of key management with relevant business / finance expertise (e.g. GE, BP, Ford, Goldman Sachs, Lazard)
• 2 x AFCs submissions (key permitting filing in CA) filed with the CEC
• 4 new dishes using the X0 design are successfully constructed and commissioned at Sandia

(II) TECHNOLOGY
A new paradigm clean energy solution
SunCatcher
• 25 kW solar power system • The system consists of a solar concentrating dish
structure that supports an array of parabolic mirrored facets
• Dish concentrator tracks, collects, and focuses the Sun’s energy onto solar receiver tubes which contain hermetically sealed hydrogen gas
• This heats and pressurizes the gas in the heater head tubing, powering a high-efficiency four-cylinder, reciprocating Solar Stirling Engine
• The Stirling engine converts thermal energy to grid-quality electricity by utilizing hydrogen as an internal working fluid that is recycled through the engine

The Stirling Engine – Invented in 1816
• Developed by leading solar industry pioneers: Ford, Kockums, Boeing, McDonnell Douglas, Southern California Edison, the Department of Energy and Sandia National Laboratories
• Track record of 20+ years of R&D and testing at a total cost of $500m

(III) CASE STUDY- MARICOPA SOLAR
Maricopa Solar – Tessera Solar’s First Commercial Plant
Unveiled world’s first commercial-scale SunCatcher Plant with Utility Partner Salt River Project on 22nd January 2010
• 1.5 MW (60 units) commercial power plant in Peoria, Arizona
• Fully assembled and online in late 2009
• PPA with Salt River Project
• Full commissioning 15th

Maricopa Solar: Installation of Pedestals
§A low-amplitude vibratory piling§No excavation§No grading§No concrete§Ease of decommissioning
Dish Assembly§ The Maricopa reached a
target rate of assembling 2.5 dishes per day
§ A PCU can be swapped for routine or unplanned maintenance in <15 min
(IV) UTILITY SCALE VERSUS DISTRIBUTED SYSTEMS
“... energy experts now say developers' focus should be on deploying smaller solar plants ... But can CSP tap into this interim market for distributed energy, or must it always be limited to utility-scale applications?”

Large V Small Scale Solar
June 29th 2010
“Building large central station solar plants and transmission lines to remote desert locations also involves major environmental trade-offs in terms of water usage and impact on virgin desert”
“The technology that is expected to dominate the distributed generation market is photovoltaics (PV). Most agree that CSP will be left to niche applications.”
Scaling down SunCatcher technology is easier than other CSP due to low water usage and modularity

SunCatcher – Modularity
The modularity of the design allows commissioning of smaller blocks which significantly reduces commissioning risk and enables revenues during the construction phase
