Project Highlights

  • One license area, Kocaköy and Gülpınar
  • Tuzla is one of the top geothermal areas in Turkey
  • Thermal bath and hot springs in the vicinity

Transmark Turkey Gülpinar's Operations

The region around Tuzla is one of the most promising areas for geothermal power production in Turkey. Several geothermal research wells were drilled by MTA (Mineral Research and Exploration Institute) during the 70’s to 90’s confirming very high temperatures and permeability in reservoirs. The highest geothermal gradient was discovered in a 130m deep well producing high rates at approximately 150°C.

With approximately 20 wells drilled  and with only four operational geothermal powerplants near Tuzla in 2021, the region remains relatively under-developed.

Transmark Renewables considers Turkey a key market due to the following characteristics:

    Strong geological potential

    • Turkey has an estimated geothermal resource potential over 4,500 MW
    • With an installed capacity in Turkey of just 30 MW in 2008, the country achieved a fenomenal growth of installed capacity to approximately 1500 MW in 2020 with governmental targets set at 3000 MW the following years.

    Attractive market fundamentals

    • With a population of approximately 80 million people and a GDP growth of 6.5%, Turkey is a large and growing economy depending largely on imported fossil energy
    • Due to these developments and the Paris agreements, the electricity market requires a strong increase of renewable energy capacity

    Feed-in tariff

    • Renewable electricity production is mainly promoted through a guaranteed feed-in tariff. Opportunities for domestic and sustainable forms of energy production – hydro, wind, solar, geothermal and others – are abundant in Turkey. Encouraging policies backed by favourable feed-in tariffs are expected to increase their shares in the national grid in the coming years.
