ÖZET Çalışmanın amacı, Bursa ili sınırlarında yer alan Çivili kömür sahasının kaynak kestirimidir. Bu amaçla sahada yapılan sondajlar, jeolojik harita ve raporlar kullanılarak bir veri tabanı oluşturulmuştur. Bu veri tabanının doğruluğu kontrol edildikten sonra katı modeller oluşturulmuş, daha sonra katı modeller, blok modellere ayrılmış ve her bir bloğun kalite öznitelikleri Jeoistatistiksel yöntemle kestirilmiştir. Kestirim için Kriging yöntemi kullanılmıştır. Ayrıca kalite tonaj eğrileri üretilmiş ve çapraz doğrulama yapılmıştır. Çivili sahasındaki linyit damarları modellenmiş, kaynak miktarı ve özellikleri Jeoistatistiksel olarak sondaj verisi azlığından dolayı 2 boyutta kestirilmiştir. Çivili sahasının güney kısmına ilave sondajlar yapılarak kaynak miktarı yeniden kestirilmelidir. 

ABSTRACT The aim of the study is to estimate the resource of the Çivili coal field which is located in Bursa-Orhaneli. For this purpose, borehole data of the field, geological map and some technical reports related to Coal Field have been studied to prepare the database. After checking the database, the solid models have been constructed. Then solid model is divided into blocks and mean qualities of each block are estimated by using geostatistical methods such as kriging. In addition to estimation, quality tonnage curves are produced and cross validation is made. In conclusion, as data are lacking, coal seams of the fields are modelled and resources are estimated in 2-D by using geostatistical methods. It is suggested that new drill holes should be made at South of Çivili coal field and the resource should be reestimated.

ABSTRACT In meeting the increasing energy needs, increasing the utilization of Turkey’s domestic lignite resources both in the generation of electrical energy as well as in heating and industry, it has always been one of Turkish Coal Enterprises’ fundamental policies in relation to natural resources to conduct the exploration, and production of local lignite resources in a manner that is compliant with the environment by using latest clean coal technologies and to exploit them in a manner that would provide the highest added value, while converting these resources into final product by processing the produced raw materials in a manner that would benefit the economy. Turkey’s annual domestic coal production is about 80 million tons and approximately %45 percent of this production belongs to General Directorate of Turkish Coal Enterprises (TKI). TKI is in the 8th place as having most employees of total and also it is in 3th place as being most profitable companies between the first 500 industrial companies in Turkey.
Turkish Coal Enterprises (TKI), the most experienced authority in coal mining sector in Turkey, was established in 1957 and has been contributing lots of experience to mining sector for 58 years.

In this study, the importance of coal in Turkey will be explained and adding to that general information the role of the Turkish Coal Enterprises will be investigated and the history of 58 years’ will be given in details. 




1     THE IMPORTANCE OF COAL IN TURKEY

1.1            Energy in Turkey

According to the data of the International Energy Agency (Coal Information 2014), there are 1,05 trillion tons of coal reserves worldwide, while 769 million tons thereof is hard coal.[i]
Global coal production in 2014 was 7,8 billion tons. Almost half of that (i.e. 3,56 billion tons) was produced by China alone. In the same period, China imported 312 million tons of coal and consumed a total of 3,872 billion tons. China’s coal production in 2013 was 3,53 billion tons.
According to many resources, coal is expected to hold the biggest share in global power generation projections for the year 2030 by several agencies. Likewise, it is forecasted that electric power generation from fossil fuels will be 20 trillion kWh (IEA, 2013). According to different resources, it is forecasted that, despite the leaps in renewable energy, the fossil fuels will gain predominance with ever-increasing speed.

1.2            Place of Coal in Energy

According to the Domestic Resource Based Energy Production Program Action Plan elaborated within scope of the Tenth Development Plan (2014 – 2018), it is known that 62 percent and 49 percent of the trade deficit resulted from net energy imports in 2012 and 2013 respectively, that oil, natural gas and hard coal imports are continuously increasing to meet rapidly growing energy demand, and that this situation leads to continuation of high import dependency in energy and creates pressure on current account balance and energy supply security.
To establish high and stable growth in Turkish economy, utilization of all possible domestic resources in energy production is deemed as a priority, which is of crucial importance for enabling sustainable development.
In this scope, the aim is to increase the share of domestic resources, including domestic and international oil and natural gas drillings, in primary energy production to 35 percent by the end of 2018 which was 27 percent at the end of 2012.
It is also aimed at increasing electricity generation from domestic coal sources to 57 billion kWh in 2018 which was 32 billion kWh in 2013.
Hence, the existing coal resources are quite important for Turkey, considering that the country has neither natural gas nor oil, which leaves coal as the only energy resource to decrease the country’s current deficit.
Turkey’s coal reserves make up 1% of the 1,05 trillion tons of coal reserves worldwide. 14,1 billion tons of our coal reserves reaching up to 15,4 billion tons together with the reserves recently discovered by MTA is lignite coal, whereas the remaining 1,3 billion tons is hard coal.
When looking at the distribution of lignite coal according to establishments, it can be seen that;
•        EUAŞ holds a share of 55% with 7,3 billion tons,
•        the General Directorate of Turkish Coal Enterprises holds a share of 27% with 3,7 billion tons;
•        the private sector holds a share of 11% with 1,6 billion tons; and
•        MTA holds a share of 10% with 1,5 billion tons. 
The installed electric power generation capacity of Turkey, which was 2.234 MW back in the 1970’s, increased by 32-fold in the last 43 years to reach 72.156 MW by October 2015. Approximately 56,4 million tons of coal were produced in our country in 2014, while thereof 85% was consumed by thermal power plants, 7,4% by the industry, and 7,6% by households.

2     TURKISH COAL ENTERPRISES (TKı)

TKI was established in 1957 under Law No: 6974. It is a State-Owned Economic Enterprise operating according to provisions of Statutory Decree No. 233. Turkish Coal Enterprises was established with the aim to make use of energy raw materials such as lignite, peat, shale and asphaltite in line with the State’s General Energy and Fuel Policy, meet the country’s requirements, and make utmost contribution to the economy of the country.
Turkish Coal Enterprises is the relevant establishment affiliated to the Ministry of Energy and Natural Resources.
TKI has a capital of 1 Billion TL, with 800 Million TL therefrom currently paid-in.
Turkey’s total coal reserves are 15,4 billion tons, while thereof 1,3 billion tons is hard coal and the remaining 14,1 billion tons is lignite coal. 3,7 billion tons of the 14,1 billion tons of lignite coal reserves is owned by TKI.
Turkish Coal Enterprises has 2 Enterprise Directorates and 1 Directorate of Operations affiliated to them. Besides, TKI carries on its activities with 6 Control Directorates which are affiliated to the General Directorate. TKI is providing employment to 19 thousand people in total, comprising 5 thousand directly employed staff and 14 thousand employed through service procurement from the private sector.
In 2013, TKI made a turnover of 2,5 billion TL and gained 178 million TL profit.
75% of its activities are carried out through service procurement from the private sector.
From among ISO 500 industrial enterprises, TKİ is ranking 4th in terms of profitability in the public sector, 5th in employment, and 5th in turnover.

2.1            Importance of TKI with regard to Coal Mining

Having achieved a growth rate of annually 5% in average during the period 2002-2010, our country ranked 17th among the world’s biggest economies in 2010 with a growth rate of 8,9%. Moreover, Turkey is a country of high potential in terms of the increase in power consumption. For instance, the country’s power consumption is estimated to reach approximately 390.000 GWh, i.e. 390 billion kWh by 2020, which means that there is a need for additional capacity in power generation of about 3.000-4.000 MW annually.
What needs to be done first and foremost to solve the problem of security of supply is to make more use of domestic resources, and then to diversify both the imported energy resources and the countries which these energy resources are imported from.
 Turkey is one of the countries that have managed to overcome the global economic crisis quickest and suffered least from the recent economic uncertainty worldwide. It is the fastest growing economy across Europe, with an average growth rate of 6% during the period 2002-2011. In 2011, the Turkish economy achieved a growth rate of 8,5% exceeding the expectations of IMF which had estimated it to be 7,5%. 
Per capita income has increased three-fold in the last 10 years, from USD 3.492 to USD 10.444. According to the Purchasing Power Parity (PPP), per capita income has increased to almost 16 thousand USD.
By means of the “Electricity Energy Market and Supply Security Strategy Paper” which was put into effect in 2009 by Resolution of the Higher Board of Planning in order to reduce external dependency of our country in energy supply, it has been decided to put in use the entire domestic coal potential of our country by 2023 and, in this scope, to increase the country’s electric energy production capacity to 100.000 MW and the domestic coal based power generation capacity to 30.000 MW.
The domestic coal based thermal power plants in our country have currently an installed capacity of about 8.729 MW.[ii] To reach the targets for 2023, there is need for additional capacity of 21.300 MW in addition to the currently available capacity.
Turkey’s total coal reserves are 15,4 billion tons, while thereof 1,3 billion tons is hard coal and the remaining 14,1 billion tons is lignite coal. Previously, TKİ owned 2,1 billion tons of the 14,1 billion tons of lignite reserves, but increased to a total of 3,7 billion tons through the new coal sites (approx. 1,6 billion tons) taken over from MTA.
Adopting a new approach which can be summarized as “collecting share from unit electric power generated from coal (royalty)”, TKİ has opened its coal sites to the use by private sector, with the condition to construct thermal power plants.
Within scope of this new method which is employed in tenders that have been and will be made and is summarized above as “collecting share from unit electric power generated from coal”, the investor is given 6 years to construct a power plant without collecting any fee for the use of coal sites put at the disposal of the investor. Starting from the end of that period, a share will be collected in return for the unit electric power (kWh) that will be generated at the constructed power plant.
The thermal power plant investment period is about 5-6 years. In order to accomplish the targets set for 2023, it is required that the foundations of these coal-based power plants are laid until 2016 at the latest.
Within scope of the mentioned targets and for the purpose of increasing the share of our country’s electric power requirement met from domestic resources, the coal site number IR-5359 (Bolu-Göynük-Himmetoğlu village) with reserves reaching up to 39 million, the ownership of which is held by the General Directorate of TKI, is being operated by AKSA Göynük Enerji Üretim A.Ş since 04.08.2006 under a royalty granted to the company with the condition to construct a thermal power plant. Construction of the thermal power plant’s 1st unit with a capacity of 2x135 MW was completed by AKSA Göynük Enerji Üretim A.Ş. in the first half of 2015. The company started to generate power under the royalty in July 2015, while the power plant’s opening ceremony took place on August 14th, 2015. The dam constructed in order to procure the water that will be used for power plant cooling activities has been completed to 99% and has a capacity of 2,25 million mᶟ.
With the 2nd unit to be commissioned by year end, the power plant will provide employment to 600 people directly, and 6000 people indirectly. This project will allow for the generation of electric power of 1,9 billion kWh annually, which is more than the 2-fold of the electricity that was consumed in the entire province of Bolu in 2014. 
Other power plant projects, which are currently under construction at sites the license of which is held by TKI, are as follows:
Owned by TKI and located at Adana-Tufanbeyli:
-        The site with 323 million tons coal reserves was contracted out on 29 May 2012 under the condition to construct a thermal power plant with a minimum capacity of 600 MW;
Owned by TKI and located at Bursa-Keles;
-        The site with 61 million tons coal reserves was contracted out on 1 November 2012 under the condition to construct a thermal power plant with a minimum capacity of 270 MW;
Owned by TKI and located at Kütahya-Tunçbilek;
-        The site with 117 million tons coal reserves was contracted out on 26 March 2013 under the condition to construct a thermal power plant with a minimum capacity of 300 MW;
Lastly, owned by TKI and located at Bingöl-Karlıova;
-        The site with 80 million tons coal reserves was contracted out on 30 May 2013 under the condition to construct a thermal power plant with a minimum capacity of 150 MW.
Another power plant with fluidized bed, which is currently under construction at coal sites the license of which are held by TKI in Manisa-Soma, is the Kolin Soma Thermal Power Plant which is constructed in an environment-friendly manner in terms of emission values, under a contract signed with Hidrogen A.Ş on 03.10.2012. Although the foundations of the plant were laid on 19 March 2014 with the participation of the Turkish Minister of Energy and Natural Resources after the licensing and EIA procedures had been completed for the project, which will have a capacity of 510 MW with 153 million tons of coal reserves capable to generate 3,7 billion kWh electric power annually whilst creating direct employment to ca. 2.600 people along with indirect employment to 26.000 people, the location of the plant had to be changed due to certain environmental problems such as olive grow law etc. EIA of the new plant location has been completed and the plant foundations have been laid in no time. Once power generation is started, the entire amount of electricity consumed in the province of Manisa in 2012, corresponding to 3,5 billion kWh will be met by this project alone.
After the contracts signed with the relevant companies, site delivery was made in line with applicable procedures.
The construction of thermal power plants with fluidized bed, which are currently under construction at coal sites the license of which are held by TKI, in an environment-friendly manner in terms of emission values, are also about to finish.
These include the following plants:
Under construction in Eskişehir-Mihalıççık:
-        The plant with reserves of 41 million tons and a capacity of 290 MW (2X145 MW) (to be commissioned in 2016);
Under construction in Silopi-Harbul:
-        The plant with asphaltite reserves of 30 million tons and a capacity of 405 MW (3X135 MW) (1st unit commissioned in 2009, 2nd unit commissioned in 2015; the 3rd unit will be commissioned in 2016 due to security problems);
To be constructed in Silopi-Üçkardeşler:
-        The plant with asphaltite reserves of 22 million tons and a capacity of 135 MW (plant foundations to be laid in 2016);
Located at Şırnak-Silopi-Sereder Sırtı Region:
-        The license of the plant with asphaltite reserves of 28 million tons and a project capacity of 270 MW was revoked by court order, but a new process has been commenced in order to complete the project. 
Plant capacities that could be potentially installed at new sites taken over by TKI from MTA are as follows:
•        Eskişehir- Alpu;
approximately 3345 MW from 1,5 billion tons of proved reserves at a quality of 2,050 Kcal/kg quality;
•        Kırklareli-Pınarhisar-Vize;
approximately 300 MW from 140 million tons of proved reserves at a quality of 1,875 Kcal/kg;
•        Konya-Ilgın;
approximately 135 MW from 30 million tons of proved reserves at a quality of 2,300 Kcal/kg.
The total capacity at new sites is approximately 3780 MW.
Apart from contracts awarded under the condition to construct a thermal power plant, there are also sites which are privatized or decided to be privatized by Resolution of the High Board of Privatization.
The plant with 457 MW capacity located at Sivas-Kangal within the body of EÜAŞ was privatized in early 2013, together with sites that have reserves of 100 million tons.
Similarly, the coal site owned by TKI with 176 million tons of reserves located at Kütahya Seyitömer was privatized by tender dated 28.12.2012, together with 600 MW power plants owned by EUAŞ.
Besides, a Resolution by the High Board of Privatization, requiring that the coal sites with 405 million tons of reserves located in Muğla Yatağan and Yeniköy owned by TKI shall be privatized by the end of 2016 together with the 1680 MW capacity plants procuring coal from those sites, was published in the Official Gazette dated 27.08.2013. The tender for the Yeniköy Thermal Power Plant and coal sites and the tender for the Yatağan Thermal Power Plant and coal sites did take place in 2014 at different dates. Contracts awarded in both of these two tenders have already been signed.
Besides, by Resolution of the High Board of Privatization dated 07.08.2014 number 2014/76, the BLI Directorate of Operations, which used to be affiliated to the GLİ Enterprise Directorate, was transferred to Soma Elektrik Üretim ve Tic. A.Ş., free of charge, together with all rights and liabilities pertaining thereto pursuant to Law No. 4046 on Privatization Practices.
In order to reach our targets for 2023 by making use of coal as the only domestic resource available to us, all necessary efforts are made at great pace to make sure that the foundations of relevant thermal plants are laid until 2016.
Thereby, TKİ will be the direct coal supplier of thermal plants which will reach approximately 7.919 MW capacity together with the new additional units that will provide 6.200 MW capacity in addition to the 1.719 MW plants owned by EUAŞ, for which TKI is already providing coal supply. All domestic lignite and asphaltitee coal based power plants to be constructed will be state-of-the-art, in other words environment-friendly in terms of their emission values.

3     CONCLUSION

Having produced 1,67 billion tons of coal in 2003, China produced 3,872 billion tons of the total amount of coal (7,8 billion tons) produced worldwide in 2014. Thus, China has pioneered the global coal sector in electric power generation all alone in recent years. Along with the excessive production of coal, a rapid increase has been observed in China’s production and consumption of energy. However, considering that developing economies will be determinative for the future “energy supply” dynamics, it must be taken into consideration that the power consumption speed in India, Indonesia, Brazil, and Middle East might get higher than that of China.
The fact that sustainable energy policies and security of energy supply are the fundamentals of a country’s development as well as economic and national security is nowadays acknowledged by almost everybody. Therefore, it is a requirement for each and every country to secure energy supply from uninterrupted, reliable, cheap, clean, and diversified resources, and to make efficient use of them.
It is necessary to adopt as a Basic Policy a standing which requires most efficient exploration and production of domestic coals in order to reduce the external dependency of our country in energy supply, while taking all environmental measures that might be necessary when making use of them.
In line with the target to put in use the entire domestic coal potential of our country by 2023 pursuant to the “Electricity Energy Market and Supply Security Strategy Paper” which was put into effect in 2009 by Resolution of the Higher Board of Planning;
it is of crucial importance to be a close follower of improvements achieved in clean coal technologies worldwide (improvements in coal firing technologies, coal gasification, coal mining etc.), taking into consideration the fact that our coal resources, among and above all fossil fuels, are
“A RESOURCE THAT MUST BE PUT IN USE WITH PRIORITY” 
As a matter of fact, considering that our country has rich lignite reserves and that future explorations might create the opportunity to discover and develop new coal deposits, it can be seen that making maximum use of coal in future for power generation purposes is quite inevitable.
