Petronet LNG Ltd. (PLL) has signed a 15-year binding term sheet with Oil and Natural Gas Corp. Ltd. (ONG) for ethane unloading, storage, and handling services, PLL said in a filing with the stock exchanges. The agreement will begin sometime in Oct-Dec 2028 and end on the 15th anniversary of the commencement date. The deal could earn PLL revenue of up to Rs. 50-bn over the 15-year period.
PLL is developing ethane unloading, storage, and handling facilities with an ethane storage capacity of nearly 170,000 cubic metres at Dahej in Gujarat. The company is also building a third jetty at Dahej, which will be capable of handling ethane and propane, in addition to liquefied natural gas (LNG).
As per the term sheet, ONGC will reserve capacity of nearly 600-ktpa at PLL’s ethane storage and handling facilities at Dahej. PLL, on its part, will receive, store, and handle ethane sourced by ONGC and its subsidiaries or affiliates at Dahej and redeliver it to ONGC at the delivery point.
ONGC seeks to import ethane as part of its long-term strategy to ensure a reliable and consistent supply of the gas as feedstock for the ONGC Petro additions Ltd. (OPaL) facility at Dahej. ONGC also plans to procure and import ethane through very large ethane carriers on long-term, short-term, and spot basis. OPaL operates one of the country's largest petrochemical complexes at Dahej, including an ethylene cracker unit that uses ethane as the primary feedstock.
