Encouraging Green Power: Cooperation between the Private Sector and Government
Avi Brenmiller, May 21 2008
What is Solar Thermal Power?
Free and secure resource, widely available and highly predictable
Uses reflectors to concentrate sun’s energy and create heat
Uniquely suited for answering peak demands
% of power generated vs. capacity

Who is Solel?
Game-changing, massive scale solutions Clean & renewable solar “fuel” for power plants One-stop solution Only commercially proven electricity-producing solar
thermal technology: California SEGS Over 300 employees – world’s largest solar thermal
company Building power plants in Spain and US Over $450 million in backlog in 2008 Ongoing major investments in R&D and production
capacity
Obstacles to solar projects (and not just in Israel)
Lack of any clear regulatory framework to govern the basic transactions
Not clear how to acquire land to build a power plant
Who would sell the electricity and who would purchase it
With which entity would a potential private supplier of electricity sign a contract
Need to be competitive from Day 1
Direct subsidy though end user’s bill, sector by sector Government revenue guarantees to producers (feed-in tariffs
protected by law – average of 0.30 € KWh up to 34.5 € KWh) Local authorities support local production with grants in
range of 30% with no tax on project revenues Commoditization of project financing process: package can
be 90% debt/ 10% equity Commercial debt packages – up to 18 or 20 years Grid connection streamlined and divided between three
agencies : production, delivery, and grid management
Encouraging Green Power :Spanish Example
Solel Solution: Utility Scale Solar Fuel
KJC Solar Plant in Mojave Desert with parabolic trough
Producing 350 MW of clean, renewable
electricity Supplying the needs of half a million
consumers Eliminating the need for two million barrels of
oil a year
The SEGS Solar Fields: Mojave Desert
Solel’s technology commercially proven Solel’s technology commercially proven
for over twenty yearsfor over twenty years
Solel recently re-supplied all of the plants’ solar receivers, upgrading output by up to 30%
Elements of a Solar Power Plant
Solar Field Power Block
HTF System Balance of plant Civil works
Solel’s SunField 6 :Built-In Solar Fuel
Change the rules of the energy equation: Solel to partner with governments, utilities, and local engineering & construction companies to build solar powered power plants
Solel offers an independent source of energy to every country with an independent source of sunshine
Plug in Solel’s clean solar field into the power plant model – no emissions
Solel’s fully engineered solar field packages fuel local job creation and economic growth
Solel offer to Governments and Utilities
