National Grid Corp. of the Philippines (NGCP) said Thursday it is set to energize major transmission projects in 2026 with a combined cost of P18.5 billion, following the completion of critical components including facility upgrades and grid stability improvements.
The grid operator targeted seven projects for completion within the year to address economic drivers such as load growth, system reliability and power quality.
These projects also facilitate the entry of new renewable and non-renewable generating plants while complementing major power grid backbones.
The 2026 rollout includes the P1.9-billion Amlan-Dumaguete 138kV transmission line, the P2.4-billion Tuguegarao-Lal-lo Magapit 230kV transmission line, the P8.1-billion Tuy 500/230kV Substation Stage 1, the P4.2-billion Nabas-Caticlan-Boracay 138kV transmission line and the P757.98-million Tacurong-Kalamansig 69kV transmission line.
NGCP is also scheduled to finish Stage 2 of its Visayas Substation Reliability project, which has an approved cost of P1.02 billion, along with the relocation of steel poles along the Hermosa-Duhat 230kV transmission line.
The company said that despite continuing challenges in right-of-way and permitting, it remains committed to the work ahead and is optimistic about completing these projects within the year.
NGCP spokesperson Cynthia Perez-Alabanza said the company continues to seek the support of government agencies and local government units to ensure the expedited release of permits, noting that their assistance is “vital to unhampered project implementation.”
The 2026 targets follow a series of infrastructure expansions in 2025 where the company completed the upgrading of 14 substations.
Key 2025 developments included the installation of a 1,000MVA transformer capacity at the Castillejos Substation and new 300MVA transformers at the Calaca and Concepcion substations.
Other 2025 completions involved 100MVA transformers for the Corella, Toril, Pitogo, Maramag, Dingle, Calbayog and Paranas substations.
The Davao Substation received a 150MVA transformer, while the San Jose and Mabinay substations were fitted with 50MVA transformers.
The company also finished a 100MVA expansion at its Iloilo Substation in April 2025 as part of the Panay-Guimaras Interconnection project. Voltage improvement initiatives were also finalized in the Tigaon, Malvar, Baybay, Sta. Barbara and Zamboanga substations.
