Prime Energy Resources Development NV completed a month-long maintenance shutdown at the Malampaya deep-water gas-to-power project, restoring domestic gas flows and clear-cutting the path for a major field expansion by late next year.

In a statement on Friday, July 17, Prime Energy said that gas deliveries from the offshore field resumed on Wednesday morning, July 15, after workers completed facility upgrades across both its offshore platforms and onshore networks.

The turnaround was the foundational groundwork for Malampaya Phase 4, an infrastructure campaign designed to integrate two new production wells—Malampaya East-1 and Camago-3—with first gas targeted for the fourth quarter of 2026.

The new wells is the most significant capital upgrade for the asset in recent years. The expansion aims to arrest declining production at the aging field, fortify the Philippines’ domestic power supply, and extend the commercial life of the asset by up to six years.

The project supplies natural gas to a cluster of power plants in Batangas province that generate roughly a fifth of the main island of Luzon’s electricity needs, shielding the grid from volatile international spot markets for imported fuels.

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

The maintenance window was critical to preparing facilities for the next phase of indigenous gas production, Cruz added.

The maintenance campaign required round-the-clock deployments of hundreds of engineers, subsea technicians, and marine crews across the Shallow Water Platform off northwest Palawan and the Onshore Gas Plant in Batangas City.

The shutdown also stress-tested the tight coordination between the operator, the Department of Energy, the National Grid Corporation of the Philippines, and downstream power generators. During the maintenance window, the field's strategic importance was spotlighted when Super Typhoon Inday disrupted operations at nearby imported liquefied natural gas terminals.

Malampaya provided emergency gas reserves to the Prime CoreGen power plants, averting forced outages and maintaining grid stability through the peak of the storm.

Prime Energy, a subsidiary of billionaire Enrique Razon’s Prime Infrastructure Capital Inc., operates the Service Contract 38 consortium with a 45 percent stake. Its partners include UC 38 LLC and state-led PNOC Exploration Corp. Over its two decades of operation, the project has contributed billions of pesos in government revenues while serving as the anchor of the country's domestic gas industry. (Gabriell Christel Galang)
