NGCP upgrades substations in North Luzon

THE National Grid Corporation of the Philippines (NGCP) on Thursday said that they had earmarked close to P10 billion for the upgrading of the 230kV Northern Luzon substation.

“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,” the NGCP said in their statement

“Without the project, power interruptions may be experienced by customers in the event of failure of existing transformers and power circuit breakers,” they added.

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 March 15, 2023, a 100MV Transformer was also energized in Laoag Substation,  Ilocos Norte.

The NGCP said that 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 P 9.93 Billion.
