The Philippines will review plans to retire the 232MW Mindanao coal-fired power plant in Misamis Oriental province because the rehabilitation of a major regional power complex could cause an electricity supply shortage.
The country could put on hold plans to accelerate the retirement of the Mindanao coal plant to 2026 from 2031, the Department of Energy (DoE) said.
The plant, majority owned by private-sector Aboitiz Power, started operations in 2006 under a build-operate-transfer (BOT) agreement with the National Power and Power Sector Assets and Liabilities Management. The plant was originally scheduled to be retired in 2031 once the BOT agreement had run its course and plant ownership transferred to the national government, but authorities later decided to shut it down by 2026. The plant consumes over 1mn t/yr of coal.
Authorities might review the retirement plans to offset the loss of power supply from the 1,000MW Agus-Pulangi hydropower complex, which will be rehabilitated next year. The complex comprises seven hydropower plants and serves as a key source of baseload power in the Mindanao grid. It is currently capable of producing only 600-700MW of power because of siltation and ageing infrastructure. Parts of the power complex are over 50 years old and its oldest dam, Agus 6, started commercial operations in April 1971. The rehabilitation involves repairing, replacing and upgrading the components of an existing hydroelectric power plant to restore its functionality, improve efficiency and extend its lifespan.
The complex will run at a derated capacity during rehabilitation works, which could take several years. This comes as power demand in the Mindanao grid continued to increase last year. Demand averaged 2.248GW in 2024, a 10.2pc increase from 2.040GW a year earlier.
The Mindanao plant could supply enough power to keep the grid stable at its full capacity, by covering for the loss in generating capacity and meeting the increase in power demand, DoE added.
