India\u2019s flagship natural gas transportation firm GAIL (India) has suggested the government meet the entire estimated cost of Rs 12,200 crore to lay a 2,539-km pipeline connecting Uttar Pradesh, Bihar, West Bengal and Odisha. The budgetary support has been sought by the public sector undertaking as it is not confident of getting enough anchor customers for the pipeline \u2014 which the government wants to build in order to boost natural gas availability in the country \u2014 to be economically viable. The Phulpur-Haldia-Ranchi-Dhamra pipeline, earlier known as Jagdishpur-Haldia line, is to be completed by 2018-19. It is expected to offer gas for revival of fertiliser units at Gorakhpur in Uttar Pradesh and Barauni in Bihar.

The government could consider to offer budgetary support so that the gap between the investment and the minimum rate of return for the pipeline could be bridged,\u201d a senior petroleum ministry official told FE. GAIL implements new projects expecting an internal rate of return (IRR) of at least 12%. The petroleum ministry\u2019s plan to offer viability gap funding for natural gas pipelines did not sail through after North Block opined that such scheme does not cover the funding for the development of gas pipelines. \u201cWhile we can confirm that phase I will be completed by December 2018, phases II and III completion will depend on the fertiliser plants coming up in the region as well as the timing of the Dharma LNG terminal,\u201d BC Tripathi, chairman and managing director of GAIL, said recently. The petroleum ministry official quoted above said that his ministry is in \u201cactive consultation\u201d with North Block to find a \u201cviable model\u201d to lay the pipeline shortly. Laying the pipeline and getting new consumers is pivotal for GAIL as well to sell around 6 million tonnes of gas it would be importing from the US beginning 2018. The pipeline, poised to make natural gas reach doorstep of every big and small gas customers in the northern and eastern states, is proposed to be built in three stages \u2014 the first phase of 755 km (Rs 3,220 crore); second phase of 1,201 km (Rs 5,565 crore) and third phase of 583 km (Rs 3,425 crore). This would include the main and the spur lines (see graphic ).
