THE National Grid Corporation of the Philippines (NGCP) has advised its customers and the general public to take necessary preparations and precautions for the scheduled 10-hour power service interruption that would hit a huge area of Northern Luzon today.
The power outage is due to the annual preventive maintenance and testing of equipment at Gamu substation.
To be directly affected are areas being serviced by the Isabela I Electric Cooperative Inc. (Iselco I) – Reina Mercedes Substation and entire franchise areas of Isabela II Electric Cooperative, Inc. (Iselco II).
Also to be affected are areas that cover the Cagayan I Electric Cooperative Inc. (Cagelco I), Cagayan II Electric Cooperative Inc. (Cagelco II) and Kalinga Electric Cooperative Inc. (Kaelco).
Aside from the annual preventive maintenance of the Gamu substation, simultaneous maintenance and testing of protection equipment will also be conducted at Santiago and Tuguegarao substations and correction of hotspots along Santiago-Gamu-Tuguegarao 230kV transmission line.
As a result of the scheduled maintenance works, power supply will be temporarily interrupted in the provinces of Cagayan, Apayao, Kalinga and parts of Isabela from 8 a.m. to 6 p.m. today.
“Normal operations will immediately resume after work completion,” the NGCP said.
