About SES

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

SES & NTR Partnership

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

SunCatcher Efficiency vs. Other Solar

High Volume, Low Cost Manufacturing Model Technologies

  • 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

  • Detroit high-performance engine manufacturer will build Stirling engine

  • Cost Reduction Drivers:

  • Economies of scale

  • Automation

  • Simplify product / reduce number of parts

  • Off-the-shelf components

  • Simplify assembly

El Centro Plant Technologies

SES Solar Two


Stirling energy systems inc

Solar Two Plant Technologies

  • Imperial Valley site designed for 750 MW, enough energy for approximately 500,000 homes

  • 30,000 Solar Dish Stirling systems

  • 20-year Power Purchase Agreement with SDG&E up to 900 MW

  • Sited on 650,000 acres at Plaster City, 10 miles west of El Centro

  • Construction scheduled for 2010 – 2014

  • SDG&E and SCE contracts support supply chain sustainability


Schedule and process
Schedule and Process Technologies

  • Application For Certification filed with the California Energy Commission June 30, 2008

  • Memorandum of Understanding with CEC and Bureau of Land Management

  • State and federal approvals required

  • Estimated approval 12 to 16 months

  • Construction Spring 2010


Jobs and cost
Jobs and Cost Technologies

  • 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


Additional benefits
Additional Benefits Technologies

  • Stirling Energy will emit no greenhouse gasses and displace tons of harmful emissions from old power plants in San Diego

  • Stirling will enhance economic development, spark solar energy generation and produce millions of dollars of new revenues for the County of Imperial

  • Solar Two will require only 33 acre-feet of water to generating 750 megawatts of clean solar energy
