NGCP strengthens Mindanao grid reliability through substation upgrades

National Grid Corp. of the Philippines (NGCP) announced that the second phase of its Mindanao Substation Upgrading Program (MSUP), with a budget of P10.56 billion, is progressing as planned.

The recent energization of a 100 Megavolt Ampere (MVA) power transformer in Davao City’s Toril Substation marks a significant milestone in this phase of the project. The Toril substation primarily serves Davao City’s electricity needs and is operated by Davao Light and Power Company.

The energization of the 100MVA power transformer is a key achievement under NGCP’s MSUP2 initiative. The project aims to equip ten substations across several areas, including Lanao del Norte, Misamis Oriental, Bukidnon, Agusan del Norte, Davao del Sur, North Cotabato, and South Cotabato, with new power transformers.

These upgrades will ensure uninterrupted power supply during outages and comply with the N-1 contingency requirement of the Philippine Grid Code. N-1 contingency refers to the ability of the grid to withstand major system disturbances without significant impact.

In the initial stage of the MSUP, NGCP successfully energized 100MVA power transformers in Agus 6, Pitogo, Placer, \NagaMin, and General Santos Substations.

Additionally, 75MVA power transformers were energized in Polanco, Opol, and Maramag Substations, while 50MVA power transformers were installed in San Francisco, Bislig, and Kidapawan Substations.

NGCP also installed capacitor banks in Butuan, Tacurong, Pitogo, General Santos, San Francisco, and Placer Substations.

NGCP expressed confidence that the energization of the transformer in Toril, along with the overall upgrades across \Mindanao, will significantly enhance the grid’s reliability.

These infrastructure improvements are geared towards accommodating the growing business, industrial, and investment activities in the region.

The MSUP2 project has a total cost estimate of P5.56 billion, following the first phase, which was approved by the Energy Regulatory Commission with a project cost of P5 billion. NGCP reiterated its commitment to expanding and improving the country’s transmission grid, aiming to deliver better services at a lower cost to consumers.
