Solar Power is inexhaustible …

Each year over 1 billion terawatt
hours of solar irradiation arrive on
Earth. This corresponds to about
60,000 times of the world's current
electricity demand. Thus, solar
power has the biggest potential of
all renewable energies.

Parabolic-trough power plants utilize proven technology

   Solar irradiation is concentrated 70-80
   times on a receiver tube, which is
   situated in the focal line of a parabolic-
   trough mirror; the heat is picked up by a
   thermo oil, flowing inside the tubes, and
   transferred to a conventional water/steam
   cycle with a steam turbine and generator
   set.

   Operation is possible in solar-only or
   hybrid mode (w/ natural gas co-firing)

   Power generation is possible on demand;
   thermal storage and natural gas co-firing
   allow power generation independent from
   actual solar irradiation

Solar Millennium meets the challenges of future
power supply

Continuous development of existing and new technologies

          Cost reduction and increased efficiency (e.g. direct steam generation)
          Extension of location possibilities (e.g. by using dry cooling)
          Electricity production around the clock (e.g. solar / biogas hybrid operation)
          Widening the possible field of application (e.g. desalination of sea water)
