CORTES, Bohol, August 13 (PIA) -- The National Grid Corporation of the Philippines (NGCP) is set to make a scheduled shutdown of the Maasin-Ubay-Corella 138 kilovolt (KV) line to finally restore to its permanent towers that have been temporarily replaced by Emergency Restoration System (ERS) towers.
That is if the local distribution companies could not get an approved islanding operation, or the use of land-based power supply generators, which are isolated from the national grid.
It may be recalled that at the peak of Typhoon Odette’s wrath, NGCP towers 43, 22, and 105, all in Leyte island, were toppled, disconnecting the power lines in the entire Bohol and some parts of Leyte.
To immediately restore the power, NGCP has to put up emergency towers called ERS to temporarily re-string the powerlines and bring the grid supply to Bohol, while the transmission company builds the replacement permanent towers.
These permanent towers are all ready to permanently carry the load which were transferred to the ERS, according to NGCP.
Because of this, there will be a scheduled power interruption along Maasin-Ubay-Corella 138KV line on August 20, 2022 from 4:00 a.m. to 7:00 p.m., according to a power advisory from NGCP.
The scheduled shutdown would facilitate the safe stringing of conductors, final clipping, reconductoring works and test as well as recommissioning of the affected towers, said Engr. Jiuseppe Lomaad, NGCP District 2 manager for Cebu and Bohol.
The 69KV Ubay-Tapal line would also be de-energized for safety purposes during the stringing operations. (RAHC/PIA7 Bohol)
