Projects Turkey


Transmark Turkey holds a production license in Çanakkale, one of the well-known geothermal regions in Turkey. Extensive surveys, well testing and simulations indicate a resource of 80 – 160 MWe in the license area of more than four thousand hectares.
  • Approximately 4,300 hectares
  • Up to 170°C geothermal water temperature in region
  • Geothermal resources with enchanting beauty among

Project Highlights

  • One license area, Kocaköy and Gülpınar
  • Transmark Turkey has a greenhouse connected to a slim well
  • Tuzla is one of the top geothermal areas in Turkey
  • Thermal bath and hot springs in the vicinity

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 170°C.

With approximately 20 wells drilled  and with only two operational geothermal powerplants near Tuzla in 2019, the region remains relatively under-developed.

Transmark Turkey Gülpinar's Operations

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

Feed-in tariff

  • Renewable electricity production is mainly promoted through a guaranteed feed-in tariff. Opportunities for 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 share in the national grid in the coming years.

Strong geological potential

  • Turkey has an estimated geothermal resource potential over 4,500 MW
  • With an installed capacity of only 30 MW in 2008, Turkey currently has around 1,347 MW of installed capacity

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
  • Due to these developments and the Paris agreements, the electricity market requires a strong increase of renewable energy capacity
