Dogal Energy Generation Co. Ltd. is a private purpose firm that has been founded initially under Art.4 of Law 3096 then granted by generation license from the Regulatory Authority for 30 years in order to realize the natural gas fired combined cycle co-generation thermal facility project ( which has 390MW Electricity and 100 MW Heat capacity).

Date of establishment : October 28 ,1997
Capital : 65.550.000.000.000 TL
Activity purpose : Establishing and operating Bogazkoy 390 MW Natural Gas Fired Thermal Power Plant


As being a Doga Holding participation , the company will build and operate a 390 MW Natural Gas Fired Thermal Plant in Istanbul-Esenyurt under Electricity Market Law as an Independent Power Producer (IPP). The project is developed in order to meet heat energy need of the region and electricity need of the country.

The electricity energy generated by the plant will be transmitted to national grid system through the 154 KV high voltage transmission line that passes over facility area.

The facility will also generate heat energy of 100MW in order to benefit from the turbines flue gas. The quantity of heat energy to be generated is determined according to the demand of the region. Heat energy will be served to household in the area through via regional heating system in the form of hot water.
