About Natural Gas


  • Historically, India has relied on coal to power its electricity sector, liquid fuels as feed stock and oil for its transport sector. But for environmental reasons we need to focus on cleaner fuels.
  • The development of Natural Gas industry in the country started in 1960s with discovery of gas fields in Assam and Gujarat. After discovery of South Basin fields by ONGC in 1970s, Natural Gas assumed importance. The Exploration activities in India were earlier carried out only by the National Oil Companies (ONGC & OIL) under nomination regime. Later private companies where allowed to enter into exploration through JV with NOCs under Pre-NELP regime. Subsequently, 100% foreign participation in exploration was allowed in the current NELP regime. Later discoveries were made in Gujarat, KG basin, Cauvery basin, Tripura, Assam etc. In 2004, liquefied Natural Gas was imported from Qatar and LNG terminal was set up at Dahej of 5 MMTPA capacity.
  • Gas is one of the cleanest fuel with less carbon dioxide per joule delivered than either by coal or oil and far fewer pollutants than other hydrocarbon fuels.

Allocation and Supply of Natural Gas:

Natural gas available in India can broadly be classified into two categories, viz. (i) Domestic Natural Gas and (ii) Imported Re-gassified Liquefied Natural Gas (R-LNG). Keeping in view the shortage of natural gas in the country, domestic gas is allocated to various sectors based on the Policy Guidelines issued by the Government from time to time. In case of imported gas, the marketers are free to import LNG and sell the RLNG to customers. A statement showing sector-wise supplies of natural gas is given in table below.

In order to enable early monetization of gas produced from small and isolated fields of National Oil Companies, the Ministry had issued guidelines on 16.1.2012 providing for allocation of gas from such fields by National Oil Companies (NOCs) through process of bidding. The limit of peak production of the field was kept as 0.1 MMSCMD for qualifying as small and isolated field. Based on the experience, the Ministry has revised the guidelines and issued fresh guidelines on 08.7.2013. In the new guidelines, the sectoral priority has been done away with and price bidding has been introduced for the purpose of selecting the customer. Further, the limit of peak production has been raised from 0.1 MMSCMD to 0.2 MMSCMD for the purpose of qualifying as a small and isolated field. The fresh guidelines are expected to lead to faster monetization with higher returns for NOCs. This initiative is likely to encourage NOCs in making investment in exploration.

Natural Gas Infrastructure in India:

Natural Gas Infrastructure consists of R-LNG terminals, Gas Pipelines and City Gas Distribution (CGD) networks.

(i) Natural Gas Pipelines:

At present, the country has a gas pipeline network length of 14,987 Km having capacity of 401 MMSCMD spread over 15 States & UTs. The details of major existing pipelines are as follows-

Natural Gas Pipelines

1 Hazira-Vijaipur-Jagdishpur -GREP-Dahej-Vijaipur GAIL(India) Limited 4222
2 Dahej-Vijaipur (DVPL)-Vijaipur-Dadri (GREP) Upgradation GAIL(India) Limited 1280
3 Uran-Trombay Oil and Natural Gas Corporation Limited 24

20 Chhainsa-Jhajjar-Hissar GAIL(India) Limited 455
21 Dabhol-Bangalore GAIL(India) Limited 1414
    Total: 14987.6

At present, there is a strong regional imbalance within the country with regard to access natural gas. Few states like Gujarat, Maharashtra and UP together consume more that 65% of the available gas, while a large number of states have no access to gas. This regional imbalance is mainly on account of lack of pipeline infrastructure in many states like West Bengal, Bihar, Jharkhand, Odisha and Chhattisgarh. In order to take the benefits associated with natural gas to all states across the nation, it is essential that the pipeline network is expanded to all regions of the country Ministry is contemplating to development of a National Gas Grid having multiple points of injection and multiple points of withdrawal. The proposed gas grid would connect the gas sources to major demand centers such as industrial clusters, big cities etc.

(ii) R-LNG Terminals:

At present, Natural Gas demand far exceeds domestic supply and this shortage is likely to prevail in the near future. Additional demand is catered through imported R-LNG. However, the demand for RLNG is price sensitive.

During 2013-14, Kochi LNG terminal having 5 MMTPA capacity for re gasification has been commissioned. With commissioning of Kochi Terminal, the total re-gasification capacity of four R-LNG terminals has increased to 22 MMTPA (79.2 MMSCMD). The capacity of these 4 R-LNG terminals is likely to be increased further to 32.5 MMTPA (117 MMSCMD) by 2016-17. The consumption of RLNG in the first six months of 2013-14 was 39 MMSCMD.

Existing Operational R-LNG Terminals Capacity

Existing Operational R-LNG Terminals Capacity

2014-15 2015-16 2016-17
Dahej PLL 10 10 15
Hazira Hazira LNG 5 5 7.5*
Kochi PLL 5 5 5
Dhabol GAIL 2 5 5
Total Existing Capacity (MMTPA) 22 25 32.5
Total (MMSCMD) 79.2 90 117

Besides the above terminals, re gasification terminals of about 35.5- 36.5 MMTPA are being planned on the eastern and western coasts of India by different entities. Development of these projects would depend on techno-commercial feasibility.

(iii) City Gas Distribution (CGD) Infrastructure:

The CGD sector comprises of Compressed Natural Gas (CNG) and Piped Natural Gas (PNG) customers. With increased availability of gas in the country, the CGD network has been enlarged to cover various cities supplying gas for domestic consumers, public transport, and commercial/ industrial entities. As on 31.12.2013, there are a total of 936 compressed natural gas (CNG) stations across the country and 24, 14,288 households with Piped Natural Gas (PNG) connectivity. The consumption of gas in the CGD network during 2013-14 was around 15.48
MMSCMD, of which 8.60 MMSCMD was used for CNG (transport) & PNG (domestic) and 6.88 MMSCMD was used for Industrial & Commercial PNG. At present, there are a number of entities operating in 47 geographical areas (GAs) and currently 18 GAs are under bidding process by PNGRB. The PNGRB has envisaged a roll out plan of CGD network development through competitive bidding in more than 300 possible GAs in a phased manner depending upon the availability of natural gas and pipeline connectivity.

In order to promote CNG (transport) and PNG (domestic) and for a developed CGD sector in the country, Ministry has taken a decision to meet 100% requirement (to the maximum extent possible) of CNG (transport) and PNG (domestic) of all CGD entities across the nation without any discrimination amongst entities. Guidelines in this regard have been issued in February, 2014. This decision has brought down the price of CNG (Transport) and PNG (domestic) across the nation and has led to increase in the consumption of natural gas, an environmentally friendly fuel, in the sector.

Further in order to bring transparency in pricing of CNG (transport) & PNG (domestic), the Ministry has issued instructions in February, 2014 to CGD entities to display the breakup of CNG price at CNG stations and to furnish the breakup of PNG (domestic) price in the invoice issued to the customers.

The Ministry is formulating guidelines relating to grant of rights to entities for sale of CNG as transportation fuel through CNG Stations. The intent of the envisaged guidelines is to promote setting up of several CNG stations in various cities/towns across the country, including along highways, and also to foster competition amongst eligible entities in the CNG segment, analogous to that in liquid transportation fuel (MS, HSD and ATF) segment. This would lead to faster rollout of large number of CNG stations across the nation.
