ENERGY DEVELOPMENT CORPORATION, about choosing EXERGY’s technology for its first geothermal brine recovery project in the Philippines:
“[Radial Outflow Turbines] … are much more compact and efficient, and use a lot less cement when they’re being constructed. Even the footprint of the radial outflow turbine plants we are buying from Italian manufacturer Exergy is much greener than the tech that was available as recently as 10 to 15 years ago… [These turbines] … will produce geothermal power at a more efficient level.”
April 2018
AKCA ENERJI regarding the TOSUNLAR geothermal power plant project initiated in 2015:
“The unit was installed successfully in 2015 utilizing the world’s first 2 pressure level single ORC turbine. The project, which was the first installation of a Radial Outflow Turbine by EXERGY in Turkey, represents a key milestone for both EXERGY and AKCA. AKCA is pleased with the decision to work with EXERGY and has no hesitation in recommending them to other potential customers.”

KARKEY KARADENIZ ELECTRIK URETIM A.S – now KARYEK – regarding the Umurlu 1 and 2 geothermal power plant project implemented in 2015 and 2016:
“The plant has worked well, achieving performance above the targets guaranteed by EXERGY. We greatly appreciated EXERGY’s full commitment to our geothermal project which proved essential to allowing Karkey to benefit from the additional feed-in-tariff for made in Turkey components and achieving the high availability record for both units. This is thanks to Exergy’s responsive and competent after-sales service, provided both on site and through proficient and timely remote control.”
October 2017
EDA RENOVAVEIS, commenting on the Pico Alto geothermal power plant project launched in AUGUST 2017:
“The construction project was a technical and management challenge, with several contractors working at the same time and, on some occasions, under harsh climate conditions. This was effectively overcome thanks to close cooperation between all the highly-specialized teams, successfully lead by EXERGY. We are very pleased with the initial production results. Over the first 2-months of operation, the Pico Alto power plant has been providing a stable and reliable supply of 4 MW of electricity to the grid. Maintaining this high performance in 2018, the annual production of the Pico Alto power plant will likely exceed the forecast made before the construction of the power plant.”
