Typhoon Tino has disrupted power supply in parts of Leyte and Samar as multiple transmission lines were knocked out, leaving thousands of customers without electricity. 

The National Grid Corporation of the Philippines (NGCP) reported outages on several key 69kV lines, affecting electric cooperatives including Leyte III Electric Cooperative, Inc. (LEYCO III), IV, V, Don Orestes Romualdez Electric Cooperative, Inc. (DORELCO), Southern Leyte Electric Cooperative, Inc. (SOLECO), Biliran Electric Cooperative, Inc. (BILECO), Surigao Del Norte Electric Cooperative, Inc. (SURNECO), Siargao Electric Cooperative, Inc. (SIARELCO), and Surigao del Sul Electric Cooperative II, Inc. (SURSECO II.)

The Maasin-Baybay 69kV line went offline at 10:35 PM, cutting power to LEYECO IV customers. In contrast, the Ormoc-San Isidro 69kV line, which tripped at 10:19 PM, left DORELCO, SOLECO, LEYECO III, LEYECO V, and BILECO subscribers without electricity. 

The Ormoc-Baybay 69kV line, down since 11:29 PM, affected LEYECO IV and V, and the Maasin-San Isidro 69kV line, which went out at 9:42 PM, disrupted SOLECO’s supply. 

The Placer-Madrid 69kV line also tripped at 10:20 p.m., leaving SURNECO, SIARELCO, and SURSECO II customers without power. 

NGCP further reported that one 138kV and one 350kV line remain unavailable.

NGCP has mobilized its line crews and is conducting patrols and simultaneous restoration activities in areas already accessible. 

“Loss of power may be caused by affected transmission facilities of NGCP or distribution facilities of local distribution utilities or electric cooperatives. 

Specific cities and municipalities affected by the power interruptions are determined by concerned Distribution Utilities, unless the outage affects the entire franchise area,” the company said.

Customers in the affected areas may experience intermittent or prolonged outages depending on the extent of the damage and accessibility for repair crews. 

NGCP is urging residents to coordinate with their local electric cooperatives for updates on restoration.
