What is the AGS Project?
Anadolu İnovasyon R&D's deep-well geothermal energy technology enables sustainable, uninterrupted energy production from high-temperature geothermal resources without any need for groundwater.
Built on work carried out in partnership with Brunel University of London, TÜBİTAK and the General Directorate of Mineral Research and Exploration (MTA), our technology focuses on using the heat stored in rock 3 to 5 km underground, and on the design and control engineering of the system.
Since 2020 our company has been active in advanced energy generation and storage technology. Our work covers AGS closed-loop geothermal applications and thermal and hydro-mechanical analysis of open-loop systems.
Technology
A fluid is heated by circulating it through the hot underground layer and is then used to generate energy.
24-hour uninterrupted power generation capable of meeting base load.
Unaffected by seasonal changes or external factors.
Long service life; removes the need for energy storage.
Innovative technology with no filtration, separation or re-injection required.
Minimal carbon footprint.
Fields of Application
We are working on our technology under the following headings.
Electricity Generation
District Heating
Ground-Source Heat Pumps
Greenhouse Farming
Heat Storage & Hydrogen
R&D Capabilities
We carry out our geothermal work across 3 research branches with 19 researchers.
- 1Formation conductivity coefficient development
- 2Time-dependent thermo-economic analysis
- 3Dynamic hybrid optimisation and control mechanisms
For system modelling and control, we have developed optimisation and control software with 2 different CFD packages, and updates are ongoing.
Converting abandoned wells
“Drilling is the largest component of well costs; personnel and equipment rental make up the main cost items at this stage.”
1
Survey and analysis
Abandoned deep geothermal and oil wells undergo geophysical surveys and thermal analysis.
2
Cleaning and heat exchanger
After cleaning and any necessary widening, a heat exchanger system is installed to the design specification.
3
Ready-to-use handover
The wells are delivered ready for use with the required cycle or heat pump application.
Why Türkiye?
Underground temperatures vary by geography. As a result, Türkiye has greater potential than many countries in terms of sites for generating electricity with enhanced geothermal systems.

Türkiye's enhanced geothermal potential is more than 4 times its annual electricity demand.
- The United Kingdom, with low geothermal potential and few hot-water sources, built its first geothermal power plant thanks to this technology.
- The USA, the EU, the UK and China are racing to bring enhanced geothermal technology home with major investments.
- Our project is supported by many institutions in Türkiye and abroad, led by MTA, the foremost authority on geothermal energy.
Economic Value
YEKDEM gross sales guarantee
$1.18M
Per year for 1 MWe of installed geothermal capacity.
Market size
$1.30 billion
Annual revenue generated by geothermal energy in Türkiye.
Sales price
$128 / MWh
Compared with $48 for solar and $54 for wind.
- Underground heat can be used to generate energy anywhere, without needing a water source.
- After licensing, Türkiye offers a 15-year purchase guarantee and additional unit-price incentives for geothermal energy.
- In Türkiye, geothermal systems have the highest local-content incentive rate of any energy system.
- Geothermal-powered greenhouse farming receives significant support and incentives in Türkiye.
- A large share of energy investment in Europe focuses on heating; AGS systems are a strong alternative for on-site heat generation.
“Over the next 25 years, geothermal is expected to be the renewable energy source attracting the most investment after solar.”
Goals
To convert hundreds of idle wells already identified as suitable in Türkiye, and to build power plants in our licensed field, including our first well, that generate steady, regular income through premium electricity sales under the YEKDEM scheme. To produce energy with two power plants of 1 MWe and 30 MWe and to build scalable systems for next-generation geothermal applications.
To become a worldwide implementer and project developer in closed-loop next-generation and open-loop geothermal applications, and to produce technology. By building systems that make the most of carbon-credit regulation and incentives, to take our place in energy transition projects in Türkiye and around the world.
