PLN EPI Secures Gas Supply of 111 Million MMSCFD from Mako Gas Field FID
PT PLN Energi Primer Indonesia (PLN EPI) has ensured a gas supply of 111 million standard cubic feet per day (MMSCFD) for 10 years from the Mako Gas Field in the Duyung Work Area following the project’s formal achievement of Final Investment Decision (FID).
This final investment decision represents a strategic measure in strengthening the supply of primary energy for power generation requirements, particularly in the Batam and Central Sumatra regions. The Mako Gas Field, operated by West Natuna Exploration Limited, is located offshore in the Natuna area, Riau Islands, at a water depth of approximately 80 metres.
The FID announcement was made at the SKK Migas office and attended by numerous officials and stakeholders from the oil and gas industry, including the Director General of Oil and Gas at the Ministry of Energy and Mineral Resources Laode Sulaiman, Head of SKK Migas Djoko Siswanto, Chairman of Conrad Asia Energy Ltd Peter Botten, and CEO of Conrad Asia Energy Miltiadis Xynogalas.
Head of SKK Migas Djoko Siswanto stated that FID approval signifies the project’s readiness to enter the construction and full execution phase. “This project represents an important step in increasing national gas production whilst ensuring the utilisation of Natuna resources for domestic needs,” said Djoko.
He explained that the Mako Gas Field project has undergone a lengthy process since the signing of the Production Sharing Contract (PSC) in 2007, gas discovery in 2017, approval of the Plan of Development (POD) in 2019, POD revision in 2022, signing of the Gas Purchase and Sales Agreement (PJBG) in 2025, and the final investment decision in 2026. Gas production from the field is targeted to commence in 2027.
Chief Executive Officer of PLN EPI Rakhmad Dewanto welcomed the achievement of the Mako Field FID as it will ensure fulfilment of gas supply in accordance with the PJBG signed between PLN EPI and West Natuna Exploration Limited on 11 July 2025. According to him, the contract is also related to the assignment from the Ministry of Energy and Mineral Resources to PLN through PLN EPI to build and operate the WNTS–Pemping gas pipeline.
“Gas supply from the Natuna region is crucial to meeting the increasing electricity needs in Batam and Central Sumatra,” said Rakhmad.
Electricity demand growth in the region is estimated to reach 12–15 per cent annually, with the majority of power plants utilising gas fuel. He added that the declining gas supply from Sumatra’s onshore areas makes supply from Natuna increasingly important for maintaining national energy security.
Director of Gas and Fuel at PLN EPI Erma Melina Sarahwati stated that construction of the WNTS–Pemping gas pipeline is currently proceeding according to plan. The project conducted groundbreaking on 10 February 2026 and is targeted to commence operations in July 2026.
This pipeline will serve as important infrastructure linking gas supply from the Natuna region to Batam’s power system.
“Development of this gas infrastructure aligns with the national energy transition strategy, which promotes the utilisation of cleaner, more efficient energy based on domestic resources,” said Erma.
According to her, this project not only strengthens national energy security but also supports efforts towards a more sustainable energy system in the future.
