DECENTRALIZED PRIVATE POWER GENERATION

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 • of experience in manufacturing ORC based power generations systems.
