The National Grid Corporation of the Philippines (NGCP) has completed the new transmission project connecting Cebu and Bohol, enabling them to also transmit power to the Luzon grid.
NGCP said the 138-kilovolt (kV) Calong-calong–Toledo–Colon transmission line went online on August 22.
The 52-circuit kilometer transmission line will boost the Visayas grid’s capability, and will be able to accommodate the 246-megawatt (MW) power plants of the Cebu Energy Development Corporation (CEDC) and the Toledo Power Company’s 82-MW coal-fired power plant.
“The completion of this project fulfilled the N-1 requirement of the transmission corridor in the Western Cebu area. This means a wider, more reliable highway for power suppliers to transmit supply to customers, particularly those served by the plants such as VECO and other distribution utilities in Cebu and Bohol,” NGCP said on Thursday.
The country’s power transmission network operator added that with the enhanced reliability of the transmission line, power supply from the Cebu power plants can reach as far as Luzon.
A new relay facility building to house associated substation equipment, sentry towers to ensure perimeter security, and slope protection for the substation and transmission towers were included in the facility in assuring structural ability.
The facility’s new capacity has complied with the N – 1 provision of the Philippine Grid Code, where it requires a back – up equipment when other facilities are unavailable or on a scheduled shutdown.
“This development is the result of a nationwide program of facility upgrades to ensure that our lines and substations operate at an optimal level and at the same time, ready to accommodate future demand or supply,” NGCP said.
The transmission company is confident that they could repeat this achievement in their other Visayan facilities.
