New Delhi: The Petroleum and Natural Gas Regulatory Board (PNGRB) has approved a revised levelised tariff for GAIL’s Integrated Natural Gas Pipeline (INGPL) network, raising the rate to Rs 65.69/MMBTU as an interim measure with effect from January 1, 2026. The order was issued on November 27.

The regulator noted in its order that the tariff determination exercise was conducted “considering the Guidelines for Determination of Natural Gas Pipeline Tariff dated 26th January, 2024.”
PNGRB said the tariff was being revised to incorporate changes relating to System Use Gas (SUG) and updated capacity assessment. The board stated, “The approved levelised tariff for INGPL is Rs 65.69/MMBTU on GCV basis. This interim adjustment primarily accounts for System Use Gas (SUG) and capacity determination.”
GAIL disclosed the tariff order to the stock exchanges on Friday, noting that the revised tariff represents a 12 percent increase over the previous levelled tariff of Rs 58.61/MMBTU.
In its regulatory filing, GAIL said the revision “represents an increase of approximately 12 percent leading to positive impact of approximately Rs 1,200 crore.”
The company added that the interim tariff adjustment will be subject to a full true-up during the next tariff review cycle. GAIL quoted PNGRB’s position that these parameters “will be subject to true-up during the next tariff review exercise scheduled to take effect from 01.04.2028.”
The PNGRB order specifies that only two parameters — SUG and capacity determination — have been considered at this stage. GAIL communicated the same in its exchange filing: “PNGRB has limited the current adjustment to SUG and capacity determination only.”

The regulator noted that all other tariff components such as operational expenditure, capital expenditure, transmission loss, revenue-sharing adjustments and working days will be evaluated in the next tariff cycle. GAIL said, “True-up of all other parameters such as actual and future Opex & Capex, transmission loss, working days, revenue-sharing adjustments, and other regulatory amendments will be undertaken during the next tariff review exercise in FY 2027-28, effective 01.04.2028.”
