Power transmission services across the Visayas Grid have returned to normal operations after National Grid Corp. of the Philippines (NGCP) completed key restoration efforts following a magnitude 6.9 earthquake in Cebu on Sept. 30, 2025.
Power transmission services in the Visayas were normalized as early as Oct. 1, even while repairs on other transmission lines were still ongoing. The NGCP said it energized the Daanbantayan–Tabango 230kV Line 2, a submarine cable linking Cebu and Leyte, on Oct. 3.
More recently, NGCP energized the Compostela-Daanbantayan 230kV Line 1 on Oct. 7 at 2: 18AM and it is now operating in parallel with the earlier restored Line 2.
Restoration works are continuing for the remaining line on outage, the Daanbantayan-Tabango 230kV Line 1. These lines provide n−1 contingency to the backbone transmission corridor already restored and do not affect any power customers.
NGCP said it deployed over 60 personnel to work on restoration activities following the earthquake, which also damaged the company’s facilities at its Daanbantayan Substation, near the epicenter of the earthquake.
“NGCP is working round the clock to ensure the stability and normal grid operations in Visayas following the magnitude 6.9 earthquake. Our teams on the ground continue their restoration and repair works to bolster the reliability of the transmission network,” the company said.
NGCP, which operates the country’s transmission highway through its franchise and concession agreement with the government, advised the public to coordinate with their respective distribution utilities and electric cooperatives for localized power interruptions.
The company said it would continue to monitor the situation and remained on alert with aftershocks still being recorded.
