A felled coconut tree caused a five-hour power outage in General Santos City and Sarangani province on Sunday, an official of the National Grid Corporation of the Philippines said yesterday.
Milfrance Q. Capulong, NGCP Mindanao regional corporate communications officer, said the power outage started at 3 p.m. with the tripping of the Matanao-GenSan 138-kilovolt line.
“A coconut tree fell in between tower numbers 38-39... Clearing works were completed and power restored at 8:20 p.m.,” she said in a text message.
The affected line is in Barangay San Pedro, Kiblawan town in Davao del Sur. Ms. Capulong did not say why the tree fell on the transmission line.
At the weekend, Davao Light and Power Co. also explained an electrocuted bird broke the line suspension insulator that resulted in an outage in a major section of Davao City’s downtown on Friday.
“Customers connected to its Gaisano substation had experienced an unscheduled power interruption , which occurred between 7:34 a.m. to 9:06 a.m.,” a company statement said, referring to DLPC.
Customers include businesses covering at least one square kilometer at the city’s central business district.
Meanwhile, Cynthia Perez-Alabanza, NGCP spokesperson, explained late last week that the recent “red alerts” in the Mindanao grid were due to a generation deficiency caused by the scheduled maintenance of some power plants, and the unexpected shutdown or reduced capacity of others.
During periods of generation deficiency, NGCP implements Mindanao grid-wide power load curtailment to maintain the power grid’s security and reliability.
“It is NGCP’s obligation under the law and its franchise to ensure that the grid operates at an optimum level with due consideration for safety, security and reliability,” Ms. Alabanza said.
Based on NGCP’s power outlook as of yesterday, the system capacity of the Mindanao grid stood at 1,276 megawatts (MW), with a peak load of 1,067 MW, or a reserve of 209 MW equivalent to roughly 20% of the island’s expected demand during the day.
