Introduction to SES
3
Overview
SES acquired the world’s most efficient solar technology, the McDonnell Douglas solar Dish Stirling system, developed at a cost of $400 million by McDonnell Douglas, U.S. DOE & Kockums of Sweden
SES develops central station solar electric plants and sells electricity through Power Purchase Agreements with leading utility companies
SES will sell equipment for turn-key solar thermal Dish Stirling electrical power plants
About SES

Strategic Partners
SES founded in 1996, based in Phoenix, Arizona
SES has outstanding technical expertise in solar energy development
NTR invested $100 million in April 2008 and continues provide millions in funding, as well as excellent proficiency in large scale infrastructure and renewable energy
Together SES and NTR are capable of building the world’s largest and most efficient solar generating facilities

Significant Competitive Advantages vs. Other Solar Technologies
2 - 3x more efficient at producing grid-quality electricity. We hold the world’s record for efficiency at 31.25% (Converts 31.25% of the energy that hits our mirrors into grid quality electric power).
Requires approximately one-half of the raw materials and cost of a solar power plant of equal output.
Uses <1% of water used by other CSP
Modular system and high availability
More flexible siting
Lower startup costs
Targeted for utility-scale power
Source: Southern California Edison and Sandia National Laboratories
SunCatcher Efficiency vs. Other Solar
Efficiency is key to SES’ cost-competitiveness

Phased Commercialization
12
High Volume, Low Cost Manufacturing Model
The SunCatcher is like a “funny-shaped” automobile
Cost Reduction Drivers:
Economies of scale
Automation
Simplify product / reduce number of parts
Off-the-shelf components
Simplify assembly
Projected cost reductions are based on a learning curve approach widely used in industry
SES is leveraging potential strategic partners and key suppliers to transform hand-built units into a high performance, low-cost product

Jobs and Cost
Total cost to build plant is approximately $1 billion
Construction jobs will range from 300 to 700 during four years
Solar Two will create more than 160 new full-time jobs to operate solar generating facility
Local job impact will be even greater with multiplier effect
