Gas Procurement


PTT purchases natural gas from various gas suppliers. We have engaged into 15 Natural Gas Sales Agreements: 12 Agreements for indigenous gas fields i.e. Pailin, Bongkot North, Bongkot South, Chevron 123, B8/32, Arthit, MTJDA A-18, MTJDA B-17, Nam Phong, Sinphuhom, , Sirikit (Lankrabue), Sirikit (Nongtoom A), and 3 Agreements for overseas gas i.e. Yadana, Yetgun and Zawtika. A total amount of gas procured in 2018 was 4,708 million standard cubic feet per day (MMSCFD) (heating value at 1000 BTU/scf)

Moreover, to ensure security of natural gas supply for the country, PTT has signed 4 long term Liquefied Natural Gas (LNG) Sale and Purchase Agreements (SPA) from global LNG players to serve an increase in Thailand’s demand. In accordance with supply, PTT has established PTTLNG, a wholly owned subsidiary of PTT, to develop, construct, own and operate the first onshore LNG receiving terminal in Thailand and South East Asia. Since 2011, the terminal has successfully provided the reception, unloading, storage and regasification/gas send-out services.The total regasification capacity has been expanded from 10 MTPA to 11.5 MTPA in 2018. While, PTTLNG is also under construction the second LNG receiving terminal which will increase capacity to 19 MTPA in year 2022.


Gas Distribution

Mainly, PTT sells the gas directly to power producers i.e. Electricity Generating Authority of Thailand (EGAT), Independent Power Producers (IPP) and Small Power Producers (SPP) through our Transmission Pipeline. The amount of gas distributed to various types of customers (including natural gas processed at the Gas Separation Plants of PTT) was as follows:

Customers 2009 2010 2011
   EGAT 1,100​ ​30.8 1,344 33.3​ 1,146 ​27.0
   IPP ​905 25.4 943 23.3​ 866​ 21.0
   SPP 456​ ​12.8 475 ​11.8 ​485 12.0
   Industry* 504​ 14.2 ​628 15.5 783​ 19.0
   Gas Separation Plants** 599​ 16.8 ​650 16.1​ 867​ 21.0
   Total 3,564/2 100.0 4,040 100.0 4,147​ 100.0

Note: The amount of natural gas was calculated at the heating value of 1,000 BTU/scf and the number of days according to the calendar year.

  1. * Including the gas sold to PTT Natural Gas Distribution Co., Ltd. and gas for transportation.
  2. ** Excluding gas to CPOC (Operator of MTJDA-B17) for running machinery at production field.

The price structure for power producers consists of two main components: well-head prices and pipeline tariffs, which is under supervision of the National Energy Policy Council (NEPC) and National Energy Policy Office (NEPO).

  • Well-head prices are a total of average price of the gas purchased from suppliers combined with procurement fee and delivery charge
  • Pipeline tariffs consist of two main parts:
    • The demand charges vary according to the location of the clients as follows.
      • ​​​Rayong Offshore 8.5899 Baht/Million BTU
      • Khanom Offshore 14.2177 Baht/Million BTU
      • Onshore 12.0654 Baht/Million BTU
        (to be paid together with the charge for Rayong Offshore)
      • Chana Onshore 2.4855 Baht/Million BTU
      • Namphong Onshore 1.1299 Baht/Million BTU
    • The commodity charge are as follows:
      • Rayong Offshore / Khanom Offshore/ Onshore 1.3380 Baht/Million BTU
      • Chana Onshore 0.0145 Baht/Million BTU
