Prime Energy has completed the scheduled maintenance turnaround of the Malampaya Deep Water Gas-to-Power Project, restoring indigenous natural gas production and moving the project closer to bringing two new wells online to extend the field’s operating life.

Gas deliveries resumed at 12:01 AM on July 15 as scheduled following the month-long maintenance campaign, which covered the project’s Shallow Water Platform off northwest Palawan and the Onshore Gas Plant in Tabangao, Batangas City.

According to Prime Energy, the turnaround also included upgrades needed to integrate the Malampaya East-1 and Camago-3 wells under the Malampaya Phase 4 (MP4) project. The new wells are expected to deliver first gas in the fourth quarter of 2026.

The Razon-led company said the additional wells will strengthen the country’s domestic natural gas supply and extend the Malampaya field’s productive life by up to six years.

“Completing this turnaround safely is essential to maintaining the reliability of Malampaya’s operations and supporting the country’s energy needs,” said Prime Energy President and CEO Donnabel Kuizon Cruz.

“This activity was also critical to preparing our facilities for the next phase of indigenous gas production so that homes, businesses and industries continue to benefit from a reliable domestic energy source,” she added.

The maintenance campaign involved hundreds of engineers, technicians, offshore specialists, marine crews, and contractors carrying out inspection, maintenance, and engineering works across offshore facilities, subsea infrastructure, and onshore systems.

According to Prime Energy, the turnaround was completed safely and on schedule despite weather-related challenges.

The company said it coordinated with the Department of Energy, the National Grid Corporation of the Philippines, and its power generation customers throughout the planned outage to implement alternative fuel arrangements and help maintain power supply.

Prime Energy added that this coordination became critical during Super Typhoon Inday (international name: Bavi), when Malampaya supplied emergency gas to Prime CoreGen power plants after severe weather temporarily disrupted LNG terminal operations, preventing a power plant shutdown through a seamless fuel transition.

Malampaya has supplied indigenous natural gas to power plants in Batangas for more than two decades and remains one of the country’s key energy assets, providing fuel for plants that supply a significant portion of Luzon’s electricity.

Will the Malampaya Phase 4 project provide enough breathing room for the Philippines’ energy security as the country works to expand its indigenous gas resources? Join the discussion.
