SLIDE 32

ORMAT’S POWER PLANT ADVANTAGES

It is a tool capable to easily accommodate changes in

reservoir enthalpy and operating conditions such as temperature and pressure

Modular development, additional units may be added later

and single units can be moved to other sites.

Air cooling enabling 100 % reinjection of the geothermal

fluid

Track record for sustaining the pressure and temperature in

the reservoir and avoiding subsidence

Simple to operate and maintain
Very high availability and low cost maintenance projects
Know how capability and knowledge incorporating 40 years
f experience in manufacturing ORC based power

generations systems.
