NATURAL GAS DISTRIBUTION AND CONNECTION LINES





NATURAL GAS PIPELINES


RUSSIAN FEDERATION-TURKEY NATURAL GAS MAIN TRANSMISSION LINE


The 842 km long Russian Federation-Turkey Natural Gas Main Transmission Line enters Turkey at Malkoçlar and then follows Hamitabat, Ambarli, Istanbul, Izmit, Bursa, Eskisehir route to reach Ankara. The pipeline has compressor stations at Kirklareli, Ambarli, Pendik, Bursa and Eskisehir and a fiscal metering station at Malkoçlar.


The construction of the pipeline started on October 26, 1986 and the line reached Hamitabat on June 23, 1987. Since then, imported natural gas has been used at the Trakya Combined Cycle Power Plant in Hamitabat. The pipeline reached Ankara in August 1988. Natural gas began to be supplied to the İstanbul Fertilizer Industry Co. (IGSAS) in July 1988, to the Ambarli Power Plant in August 1988 and to Ankara for residential and commercial purposes in October 1988. The use of natural gas by the industrial sector started in August 1989.

The Eastern Anatolia Natural Gas Main Transmission Line aims to transport natural gas produced mainly in Iran and other countries to the east of Turkey.


In this context, a Natural Gas Sale and Purchase Agreement was signed on August 8, 1996 between the Republic of Turkey and the Islamic Republic of Iran according to which natural gas delivery to Turkey would start at a volume of 3 bcma to reach 10 bcma on a recieving basis.


The Eastern Anatolia Natural Gas Main Transmission Line is approximately 1,491km-long with a diameter varying from 48” to 16” starts from Doğubayazıt and reaches Ankara through Erzurum, Sivas, and Kayseri, and another branch thereof reaches Seydişehir through Kayseri and Konya.


The complete pipeline system was ready for gas transportation as of June 2001. Natural gas delivery from Iran started on December 10, 2001 with the completion of the Bazargan Metering Station in Iran.





SAMSUN - ANKARA NATURAL GAS TRANSMISSION LINE


A 25 year term Sale and Purchase Agreement was signed on December 15, 1997 by the Russian Federation and Turkey. Under this Agreement 16 Bcma of Russian gas would be transported.


The Russian Fed.-Black Sea-Turkey Natural Gas Pipeline;

The pipeline within the Turkish territory surfaces at Samsun and follows Amasya, Corum, Kirikkale and ends in Ankara.


The system became operational and natural gas delivery from the Russian Federation was started on 20 February 2003.





TURKEY – GREECE NATURAL GAS PIPELINE


In association with the European Union INOGATE Programme (Interstate Oil and Gas Transport to Europe), which was developed for the transportation of natural gas via Turkey and Greece to be supplied from Caspian Basin, Russia, Middle East, South Mediterranean countries and other international sources to the European markets.


The Turkey – Greece Natural Gas Transmission Pipeline is the first stage of the project. The Line pipe diameter is 36 inches. Total length is 296 km. Turkey has 211 km and Greece has 85 km. Between Karacabey and the Marmara Sea (Değirmencik) is 121 km, the Marmara Sea Crossing (Kızılcaterzi) is 17 km, the Trakya section is 73 km.


In addition, the 420 m long (Meriç / Evros) River crossing was implemented by horizontal drilling. The pipeline enters into Greece from İpsala and ends in Komotini.


The Commercial Agreement was signed in December 23, 2003 between BOTAS and DEPA. The quantity of gas supplies to Greece in 2006 was 250 Million m³, whereas it will subsequently reach to 750 Million m³ per year.


The constructions of the Land Section (Lot-I) was completed on July 30, 2007, Sea Section (Lot-II) was completed on July 05, 2007 and Meriç-Evros River Crossing (Lot-III) was finished on August 18, 2007.


The Pipeline construction started in 2005, was completed and became operational on November 18, 2007.




AZERBAIJAN – TURKEY NATURAL GAS PIPELINE (Sahdeniz)


An agreement was signed between Turkey (BOTAŞ) and Azerbaijan (SOCAR) for the transportation of natural gas via Georgia which will be produced in Azerbaijan. Within the scope of this agreement, the Azerbaijan – Turkey Natural Gas Pipeline project was developed and awarded in three (3) phases.


Phase I and Phase II were awarded on May 04, 2005, and Phase III comprising construction of both the Hanak Compressor Station and Türkgözü Metering Station was signed on September 23, 2005.


The Azerbaijan – Turkey Natural Gas Pipeline Phase I was completed in December 30, 2006 starting from the Posof district of Kars province near to the Turkey – Georgia border. It has approximately 113 km length and 42 inches diameter. Besides, natural gas was also supplied to the Ardahan province.


The Turkey – Azerbaijan Natural Gas Pipeline Phase II, started upon the completion of Phase I and extended to the Erzurum – Horasan direction was completed on March 09, 2007. Natural gas was also supplied to the Kars district.




KARACABEY - İZMİR NATURAL GAS TRANSMISSION LINE


Within the scope of the studies for widespread gas usage throughout Turkey, the main line will be extended from Bursa (Karacabey) to Izmir - Aliaga so that natural gas would be supplied to the industrial and residential areas on route.


The Bursa - Can Natural Gas Transmission Line was the first phase of the Aegean Line to be completed and become operational in 1996. It the second phase of the Project the line will be extended from Bursa- Karacabey to İzmir. Within this Project; for the purpose of supplying natural gas to the Aliağa Combined Cycle Power Plant and the industrial areas, a 35 km. connection line to Aliaga Combine Cycle Power Plant and 7 km long Aliağa Branch line was built.


The construction of the 241 km. long line was completed in 2003.
