MANILA — The Malampaya Deep Water Gas-to-Power Project will undergo a scheduled maintenance shutdown for one month starting next week, the Department of Energy (DOE) said.

The DOE said the maintenance activity will run from June 15 to July 15 and will cover key facilities at the Shallow Water Platform in offshore northwest Palawan and the Onshore Gas Plant in Tabangao, Batangas City.

The works will include integrity inspections, servicing of mechanical and control systems, and other safety-critical maintenance activities aimed at ensuring the long-term reliability of operations.

The energy department said the scheduled shutdown was coordinated with relevant stakeholders.

“During the maintenance period, the supply of natural gas from Malampaya will be temporarily halted, requiring power plants to switch to alternate fuel sources,” the DOE said in a statement.

Aside from routine maintenance, the DOE said the tie-in of the Malampaya East-1R1 (MAE-1R1) and Camago-3S3 (CA-3S3) wells will also be undertaken.

“This integration of newly discovered wells into the existing infrastructure will bolster the nation’s indigenous natural gas supply and extend the project’s operational life,” the DOE said.

The Malampaya Deep Water Gas-to-Power Project, located off the coast of Palawan, remains the country’s only indigenous source of natural gas and supplies up to 20 percent of Luzon’s electricity needs.
