Aside from Steag’s maintenance shutdown, which was scheduled until Nov. 10, Mindanao’s power supply was also affected by the decreased production due to low water inflow of the NPC’s Pulangi IV hydroelectric plant in Bukidnon.
Pulangi IV reduced its generation capacity from 180 MW to 150 MW due to the plant’s declining water inflow.
“Socoteco II will maximize and dispatch any available power supply. If, during the day, there will be a system improvement, some feeders may experience shorter than the announced duration of brownout,” Desesto added.
Engr. Joseph Yanga, Socoteco II technical services supervisor, said NPC and NGCP reduced the area’s power allotment to 53 MW due to the earlier cutoff from the Mindanao grid of one of Steag’s two 105-MW generating units.
He said such allocation was 57 MW short of the city’s daily peak power demand of 110 MW.
Yanga said Aboitiz-owned Therma Marine Inc. augments the area’s requirement by 30 MW based on a supply contract earlier forged by Socoteco II. (Allen V. Estabillo/MindaNews)
