[9][10][11][13] With the initiative of the governmental Electrical Power Resources Survey and Development Administration (Turkish: Elektrik İşleri Etüt İdaresi, EIE), a research project was started by Zorlu Petrogas Oil &Gas group.

[16] In December 2011, the provincial administration allocated 70 decares (70,000 m2; 750,000 sq ft) land needed for the construction site of the geothermal power plant expansion.

The project forecast 575 GWh annual electrical energy generation, and a contribution to the country's economy at US$60 million yearly.

The geothermal fluid would be used also in dry ice production and for heating in greenhouses and households in the villages around the power plant.

[1][2][17][18] Kızıldere geothermal field is situated at the western branch of Büyük Menderes Graben within the limits of Denizli Province.

[3][6][8][9][10] The first geological and geophysical surveys in the Kızıldere geothermal field began in 1965, and were carried out by the state-owned Turkish Mineral Research and Exploration Co. (MTA).

The calcium carbonate dissolves from the rocks and later gets deposited as limescale on the instruments in the geothermal well and at the brink, such as demisters, heat exchangers, and other locations, and this causes a drop in pressure.

[3][5][6] In addition to electricity generation, the geothermal fluid serves for processing of carbon dioxide gas as a byproduct, and this is used in dry ice production at two nearby plants.
