Oil India Ltd (OIL) on Monday announced that it has signed a long-term Gas Sale and Purchase Agreement (GSPA) with North Eastern Electric Power Corporation (NEEPCO) for the continued supply of 1.4 million metric standard cubic metres per day (MMSCMD) of natural gas.

Under the new pact, OIL will supply gas to NEEPCO’s Assam Gas-Based Power Station (AGBPS) at Bokuloni in Dibrugarh district for another 15 years, extending their existing 10-year arrangement.

“The new 15-year agreement succeeds the earlier 10-year deal, ensuring uninterrupted energy supply to the region,” OIL said in an official statement.

Through this partnership, OIL and NEEPCO aim to enhance energy security in Assam and the Northeast, supporting India’s goal of ensuring affordable and clean energy access.

The AGBPS, Assam’s largest gas-based power station, plays a key role in meeting the region’s electricity demand. The station relies on OIL’s consistent natural gas supply to maintain stable operations and meet growing consumption needs.

“The signing of this extended-term agreement reaffirms OIL’s commitment to leveraging its robust reserve base and production capabilities to ensure a sustainable gas supply from domestic sources,” the company added.

The long-term arrangement strengthens both organisations’ contributions to regional energy reliability, while aligning with India’s broader clean energy and sustainability goals.
