Ormat Technologies, Inc. (NYSE:ORA) announced that it has completed the modification of the 20MW Burdette (Galena1) geothermal power plant into an Evaporative Cooling configuration.

This modification is another step in a multiyear research and development (R&D) program that tested different methods to implement evaporative cooling as well as the associated water treatment solutions. 

Evaporative cooling allows increasing power generation from air cooled facilities by as much as 30% during the hot hours of the day. 

The implementation of this system in the moderate to dry climates, especially in the High Desert, generates more energy per year than water cooled systems with a fraction of the water and chemical consumption of a traditional water cooled system. 

From the consumer's side the implementation of this system further increase the value of geothermal energy as it increases the available energy to the grid at "Summer Peak", the hours of high demand, while maintaining it smooth and predictable dispatch curve which is not affected by temporary cloud coverage or changes to the wind regime. 

Ormat currently operates approximately 180 MW in suitable climates and expects to add another 60MW in the near future. Ormat plans to implement the learning from the operation of the Burdette plant both in its existing fleet and in future installations.
