Iligan City, Philippines – Short rotational power outages are expected in some areas in Mindanao as four hydroelectric plants and two independent power producers undertake repairs and preventive maintenance work this week.
Thus, the National Grid Corp. of the Philippines (NGCP) said it has asked power utility firms and electric cooperatives in Mindanao to set up a load reduction plan amid the situation.
Eugene Bicar, NGCP-Mindanao systems operation head, said the power plants have been temporarily shut down for preventive maintenance work.
He said requests have been made to power utilities and electric cooperatives in Mindanao to drop some of their feeders to address the generation problem and prevent overloading of transmission lines.
Power supply is now limited as the Agus 1 (unit 2) in Marawi City, Agus 5 (unit 1) in Iligan City, Agus 2 (unit 1) in Lanao del Sur, and the Pulangi hydroelectric plant in Bukidnon are now temporarily shut down.
Also in the same situation are the Western Mindanao Power Corp. in Zamboanga City and the STEAG coal-fired power plant in Villanueva, Misamis Oriental.
“Short rotational (power outages) in some areas in Mindanao are expected during the peak hours from 10 a.m. to 4 p.m. and 6 p.m. to 8 p.m. daily based on actual system condition until curtailment is lifted,” Bicar said.
However, he said steps are being made to correct the problems of the power plants as soon as possible so that power supply in the Mindanao grid is normalized with a comfortable level of generation reserves.
