Diler Holding intends to increase the business volume and diversify the fields of activity. Considering the projection of a national electric energy deficit and the power consumption of the Holding, investments in electricity generation reveals itself as a proper option. It is worth mentioning that average electrical power demand of the affiliated companies of the Holding is 200 MW on average. For this reason, Diler Holding intends to become one of the groups that make remarkable contribution to the power industry in Turkey. To attain its targets it established Diler Elektrik Üretim A.Ş. in 2005 and Atlas Enerji Üretim A.Ş in 2008.
Atlas Enerji Üretim A.Ş. was founded for electricity generation and trading activities. Registered office of the company is in Istanbul, whereas all official procedures and technical issues relating to projects are conducted by the representation office seated in Ankara. Coal fuel thermal plant is managed from Iskenderun.
Atlas Enerji Üretim A.Ş. obtained from the EMRA (Energy Market Regulatory Authority) a power generation license for 2 x 600 MW Coal Fuel Thermal Power Plant Project in Iskenderun. The company is planning to establish natural gas, wind and geothermal power plants on the long run.
2 x 600 MW Thermal Power Plant Project has been completed in two stages. In the phase 1, the two units and shared facilities of the two units (i.e. chimney, turbine-generator building, water treatment facility building, cooling with seawater construction works, coal storage room have been constructed. The two units will generate 8.500.000 kWh per year.
Supercritical boiler technology has been preferred in design for imported coal fuel power plant, and sea water has been used for cooling water. Power plant operates in compliance with the environmental legislation of Turkey.
EIA (Environmental Impact Assessment) approval was obtained from the Ministry of Environment and Forestry for the thermal power plant project in Iskenderun. The project covers an area of 180,000 sqm in total. Location of the map is shown in the following map.
The first unit was commissioned in August 2014 followed by the second unit in December 2014. 15% of generation is sold at the steel factories of the Holding, while the remaining is offered for sale on free market.
Thermal power plant provides employment nearly for 280 employee.
Annual power consumption per person is 2,090 kWh in Turkey, which is below the average of 6,460 kWh in the European Union. According to projections of the Ministry of Energy and Natural Resources (MoENR) for 2004-2020, annual power consumption rate per person will have reached 5,700 kWh by 2020 with a cumulative annual rate of increase by 7.7% in Turkey.
Atlas Enerji Üretim A.Ş, is one of the significant participants of the power industry in Turkey.
2 X 600 MW ATLAS ISKENDERUN THERMAL POWER PLANT
The power plant is established on 180 hectare of area situated in Iskenderun Organized Industrial Zone, nearly 10 km north from Iskenderun. Power generation facilities is 400 m inner the coasts of Mediterranean, next to Yazıcı Demir Çelik San. ve Turizm Tic. A.Ş., an iron and steel factory owned by Diler Holding.
Waste storage area is on a valley that is nearly 14 km distant from the power plant.
As ashes, plaster are raw materials of cement industry they are sold to relevant factories as semi-finished goods.
Turkish Electricity Transmission Company (TEİAŞ) supplied connection to the binding post that is nearly 1 km distance from the power plant.
Primary fuel of the power plant is imported coal with lower calorific value of 6.000 kCal/kg. Natural gas will be used as the initial fuel in the power plant.
Coal is transported to the power plant through the port of Yazıcı Iron-Steel facilities.

Environmental Awareness
Turkey pays attention to put the EU legislation and policies in practice. For this reason, best available techniques have been used for preventing air, water, soil and noise pollution in the project.
Legal, administrative and technical measures to determine the effects of thermal power plant on the physical and biological environment and to prevent, reduce and rehabilitate such effects are explicitly defined in the Environmental Impact Evaluation Report of the project. Pursuant to the cited Report, all environmental effects of the power plant ü including the waste (gas emissions, liquid wastes) are compatible with the Turkish Environmental Legislation.
Power Plant Technical Specifications, which constitutes an integral part of the agreement executed by and between Atlas Enerji and the contractor company, were prepared in the light of the conditions stipulated by the Turkish Environmental Legislation. Gas emission values specified in the Agreement and EIA Report are as follows:
| Emission parameter |
Emission Values (mg/Nm3, based on 6% oxygen) |
|

NOx (as NO2 ) |

As is seen on the table above, Atlas Iskenderun Thermal Power Plant has 10 mg/Nm³ value, and s the cleanest power plant in Turkey in terms of flue gas powder emission as bag filter system was used instead of classical electrostatic filter.
Particle concentration of the gas on the chimney outlet will be 10 mg/Nm³. Although the chimney height appears to be 100 m in the calculations made in compliance with the environmental legislation, it was resolved to construct the building height at 210 m to attain better gas emission values around Atlas Enerji project site as specified in the agreement specifications and in EIA Report.
Flue gas NOx concentration is reduced to limiting values in desulphurization (deSOx) process with the method of wet lime at the SOx concentration Flue Gas Desulphurization Facility absorption tower through the denitrification (deNOx) unit.
An Air Pollution Distribution Modelling was performed in the light of SO2, NOx and particle (powder) mass flows from the chimney, other gas emission sources around the project site, chimney height, flue gas outlet velocity, meteorological and topographical conditions by an expert company approved by the Ministry of Environment and Urban Planning in order to determine the effects of the power plant on the existing air pollution in the region pursuant to the Regulation on Controlling Industrial Air Pollution.
As specified in the aforementioned Regulation, the air pollution modelling was performed for an area of 21 km x 21 km dimensions' in the center of which is the thermal power plant erected and the chimney height contains a circle with a radius 50 times greater than it (210 m x 50 = 10.500 m). The potential pollution levels were examined in the cited area, and results were calculated for the pollution concentrations on the level ground.
The air pollution modelling demonstrated that the potential emissions from the power plant would not substantially alter the existing air quality, and that gas emission values would not exceed the given limiting values even under the worst conditions for operation.
Flue gas emission values emerging from coal firing at the power plant are monitored constantly, the flue gas flow is measured constantly, and results are recorded for PM (powder), O2, SO2, CO, NO2, temperature and mass flow; subsequently results of such measurements are furnished to the Ministry of Environment and Urban Planning in real time (online).
Coal is imported in compliance with the "Communiqué on Foreign Trade Standardization for Environmentally Controlled Fuel Importation" published on the Official Journal on 31.12.2007.
Coal to be imported for the power plant is unloaded at the port and is subsequently transferred to coal stockyard through conveyors inside the closed drifts equipped dusting preventive and dust catcher equipment. Closed coal conveyor drifts after the coal stockyard, coal breaker premises and coal bunkers are also equipped with dust catcher systems.
There are 3 ash hoppers, each with 1200 cubic meter capacity inside the power plant site. Fly ashes are pneumatically sent to the hoppers from the boiler.
Sea water and cooling system of the power plant are also compatible with the Turkish Environmental Legislation in terms of features of the water that will be discharged to the sea (ΔT temperature rise included).
Waste water emerging from different sections of the power plant are treated at the waste Water Treatment facility, and is subsequently discharged to Organized Industrial Site Treatment facility under conditions satisfied as per the Regulation on the Control of Water Pollution.
Fresh water, which will majorly be used as boiler feed make-up, will be met from the Desalination Facility, which will convert salty water from the sea to fresh water. The capacity is 450 ton/h. Fresh water, which is a product of desalination, will be subject to demineralization afterwards. Fresh water requirement of the facility is approximately 420 ton/h.
Power plant equipment has been selected as per the noise levels that would not exceed the limiting values specified in the relevant legislation.
