Why it matters:
These projects add 450 megavolt-amperes (MVA) of capacity, supporting the surging electricity demand in high-growth areas while preparing the network to withstand extreme weather and shifting consumption patterns.
"These projects are part of Meralco’s broader network enhancement strategy, ensuring that our infrastructure is future-ready to meet growing energy demand while improving operational flexibility and service reliability," said Froilan J. Savet, Meralco first vice president and head of networks.
Capacity boost in key areas
Metro Manila upgrades:
ASEANA GIS Substation (Parañaque City): A new smart substation now supports major commercial hubs, including ASEANA 3, Ayala Malls Manila Bay, Seda Manila Bay, and Uni-Asia International Prime Holdings Inc.
Bridgetowne GIS Substation (Pasig/Quezon City): Expanded to meet the needs of Giga Tower, Tera Tower, Opus Mall, and GBF Center.
Makati GIS Substation: Enhanced capacity for key customers like Cash & Carry Mall, St. Clare’s Medical Center, and SMDC Red Residences.
Southern Luzon expansion:
Tayabas Power Transformer upgrade: Increased from 100 MVA to 300 MVA to support load growth in Quezon and Laguna.
Strengthening the network backbone
Meralco energized five sub-transmission system projects aimed at improving operational reliability and supporting major infrastructure developments:
Laguna: Capacity of the Dila–Real 115 kV line was increased, enhancing reliability for Calamba, Los Baños, Bay, Pila, and Calauan.
Bulacan: The Malolos–Tabang and Malolos–Calumpit 69 kV lines were energized to support rising demand and the Department of Transportation’s North-South Commuter Railway project.
Quezon City: Meralco launched its first fully indoor GIS switching station in Regalado, improving switching flexibility and reliability for critical facilities such as ST Telemedia Global Data Centers.
Cavite: The Abubot Substation was upgraded with three new 115 kV circuit breakers, bolstering supply to customers in Dasmariñas, General Trias, and Imus, including De La Salle University Medical Center and San Miguel Yamamura.
Bigger picture
These Q2 projects are part of Meralco’s ongoing network modernization plan, which aims to:
Anticipate long-term demand growth in residential, commercial, and industrial sectors.
Support key economic zones and infrastructure projects.
Ensure resilience against power interruptions caused by climate-related risks.
What they’re saying
"These infrastructure investments reflect our unwavering commitment to power progress and ensure that our customers have access to reliable, sufficient, and high-quality electricity. As demand continues to grow, we will continue to upgrade and expand our facilities and strengthen our distribution network which serves as the backbone of our efforts to support the country’s economic development," Savet said.
The bottom line:
Meralco’s Q2 investments strengthen the reliability and flexibility of the power grid, positioning it to meet future energy needs while supporting the country’s economic and infrastructure growth. —Ed: Corrie S. Narisma
