NGCP upgrades substations in North Luzon
Published on April 20, 2023 12:00 AM
To further improve power transmission services, NGCP recently energized new power transformers in several substations as part of the second stage of its North Luzon Substation Upgrading Project.
In February, NGCP energized its 100 MegaVolt-Ampere (MVA) Transformer 1 in Tuguegarao Substation in Cagayan, and another 100MVA Transformer 1 in San Esteban Substation in Ilocos Sur. On 15 March 2023, a 100MV Transformer was also energized in Laoag Substation, Ilocos Norte.
“The upgrading of these substations is being done to cater the load growth and provide N-1 contingency to substations in NGCP’s North Luzon Region. Without the project, power interruptions may be experienced by customers in the event of failure of existing transformers and power circuit breakers”, said NGCP.
A requirement of the Philippine Grid Code, an N-1 contingency is the ability of the grid to withstand a major system disturbance with minimal or no impact to the system.
Besides these provinces, NGCP is also set to upgrade its substations in other areas such as La Union, Nueva Vizcaya, Isabela, Pangasinan, Tarlac, Pampanga, Zambales, and Nueva Ecija.
The overall substation upgrading project has already been filed with the Energy Regulatory Commission (ERC) with a total project cost of PhP 9.93 Billion.###
