EXERGY's AKÇA plant is situated in the Denizli region in Turkey. This is a low enthalpy geothermal plant (fluid temperature at 105 C°/220 F°) generating a power output of 4 MW.
EXERGY are proud to announce the operational launch of another geothermal plant in Turkey for the client AKÇA ENERJI. With the successful completion of this ORC binary installation, the Akca plant will be the world’s first equipped with 2-pressure-level cycle on a single-disk turbine. This unique technological achievement sees EXERGY at the forefront of innovation consistent with its commitment to improve technical performance and deliver superior service to customers. The Turkish Ministry of Energy and Natural Resources confirmed in June that the plant meets the required performance targets. AKÇA ENERJI will therefore benefit fromincreased revenues coming from the government feed-in-tariff improving the payback of the geothermal plant.
The AKÇA plant, situated in the Denizli region, is a low enthalpy geothermal plant (fluid temperature at 105 C°/220 F°) generating a power output of 4 MW. The installation of the innovative Radial Outflow Turbine, EXERGY’s core development of turbine design, enabled EXERGY to offer the client a superior plant performance with 2 pressure levels with a single expander, producing up to 20% more power than competitors using a single pressure level system. The performance tests EXERGY’s staff conducted on the plant have given extremely positive results indicating a very high turbine efficiency, over 5% more than the guaranteed figures provided to the client.
This new binary plant configuration will increase the feasibility of low-enthalpy 3-8 MW range plants down to 100 °C and open up new possibilities for EXERGY clients to exploit low enthalpy small resources more efficiently and economically than ever before.
EXERGY’s CEO Claudio Spadacini commented on this new achievement: “We are very proud of the new goal we have reached with the AKÇA plant. This project, representing a milestone in the EXERGY portfolio, is the outcome of the technical strength and combined effort of EXERGY’s talented team. Moreover, it confirms once more the competitiveness and validity of our Radial Outflow Turbine technology to provide higher efficiency and its flexibility to adapt to diverse conditions. Thanks to our technology, our client AKÇA will benefit from a new source of energy in a more efficient and profitable way.”
