As commercial centers multiply and new communities rise across the Philippines, the demand for dependable electricity continues to intensify, pressing the energy sector to move faster and build smarter. For Manila Electric Company (Meralco), this means ensuring that power infrastructure keeps pace with the country’s changing economic landscape and the growing needs of millions of consumers.
As the country’s largest power distributor, Meralco has been ramping up major infrastructure developments and system upgrades across its franchise area, reinforcing substations, energizing new lines, and adopting smart technologies aimed at delivering reliable, stable, and high-quality electricity service to more than eight million customers.
Even without a distribution rate increase in more than a decade, the utility continues to pour billions into strengthening its network, securing supply, supporting industrial expansion, and preparing for a more digital and decentralized energy future.
In the final quarter of last year alone, Meralco energized six major capital expenditure projects covering key urban centers in Mega Manila as well as rapidly growing areas in Bulacan, Cavite, and Laguna. These projects were designed to improve grid reliability, enhance operational resilience, and expand capacity in areas where energy demand continues to climb.
In the northern part of its franchise, Meralco energized the new Cruz-Na-Daan–Alagao 69-kilovolt Line 2 in Bulacan. Stretching 25.26 kilometers, the transmission line links the Alagao Switching Station to the Cruz-Na-Daan Substation and is expected to provide more stable, resilient, and dependable electricity to residential and industrial customers in San Ildefonso, including Eagle Cement Corporation and Solid North Minerals Corporation.
The company also upgraded its Camarin Substation to improve service reliability and stability in Caloocan City and San Jose del Monte, Bulacan. The project is expected to support rising power requirements in North Caloocan and parts of San Jose del Monte, serving customers such as Maynilad Water Services’ La Mesa Water facility, SM Deparo, SM City San Jose del Monte, Regan Industrial Sales Inc., and Converge J3 Caloocan DC.
In the South Luzon corridor, Meralco completed four critical projects aimed at supporting some of the region’s most dynamic development hubs. Among these was the commissioning of the Island Cove Gas-Insulated Switchgear Substation, which was built to address growing demand in Bacoor, Imus, Kawit, and Noveleta in Cavite.
The new facility is expected to benefit a broad mix of institutional, commercial, and healthcare customers, including Bacoor City Hall, Evo City of Ayala Land Inc., SM City Bacoor, Cavite Medical Center, and Binakayan Hospital and Medical Center.
Meralco also upgraded its San Pedro Substation with the installation of a 34.5-kilovolt Modular Gas-Insulated Switchgear to enhance service reliability in San Pedro and Biñan in Laguna, as well as Carmona in Cavite. Beyond improving power stability, the project is also expected to reduce operational and maintenance costs while serving key communities and large-load customers such as San Pedro City Hall, ON Semiconductor, and Golden Mile Business Park.
To further reinforce Laguna’s industrial corridor, the company modernized the Sta. Rosa II Substation and the Laguna International Industrial Park Substation. The upgraded Sta. Rosa II facility is expected to serve major residential communities, commercial developments, and industrial locators, including Ayala Westgrove, Microtel South Forbes, De La Salle University, Toyota Boshoku, Panasonic, Honda Cars, Furukawa Electric, and Hankyu Hanshin Logistics.
Meanwhile, the enhanced LIIP Substation will support industrial customers such as Toyota Motor Philippines, AICHI Forging Co. of Asia, Zenith Technology, IMASEN Philippines Manufacturing Corp., Ryonan Electric Philippines Corp., Santo Plastic Philippines, and D.W. Plastic Corp. It will also deliver stronger and more consistent power service to nearby commercial establishments and residential communities, including Waltermart Bel-Air Sta. Rosa, Grand Chestnut Grove, and Berkeley Heights.
These developments come as Meralco prepares for its next regulatory period, or First Regulatory Period, covering July 2026 to June 2030, following the Energy Regulatory Commission’s approval of the Rationalized Rules for Setting Distribution Wheeling Rates under Performance-Based Regulation. Under this new cycle, the utility is proposing a ₱272-billion capital program aimed at sustaining reliability, integrating renewable energy, and expanding customer choice.
The scale of the planned investment signals Meralco’s push to build a stronger and more adaptive network that can reduce outages, improve system redundancy, and future-proof electricity service. “This rate reset will enable Meralco to pour in massive investments for storm-hardening, upgrading, and expansion of our facilities, as well as technological advancements necessary to future-proof our distribution network.
These go alongside our efforts to ensure fewer interruptions and faster service restoration, promote consumer empowerment, and support government-mandated customer choice programs,” said Meralco Senior Vice President and Head of Regulatory Management Office Atty. Jose Ronald V. Valles.
Beyond physical upgrades, Meralco’s proposal includes a broad pipeline of programs meant to address sustained customer growth, improve system reliability and power quality, and raise the standard of customer service while responding to new requirements in customer choice, real-time energy management, distributed energy resources, battery storage, sustainable mobility, and cybersecurity.
A major share of the proposed capital outlay will fund the expansion of both electric and non-electric infrastructure. This includes the development of 25 distribution substations and three delivery point substations, along with the construction and expansion of eight operating centers and 10 business centers designed to bring personnel closer to communities and improve customer touchpoints.
These projects are seen as essential to serving Meralco’s more than eight million customers and managing peak demand that now exceeds 9,000 megawatts. Underground cabling projects in selected areas are also being pursued to further strengthen system resilience.
At the core of Meralco’s modernization push is its Advanced Metering Infrastructure Program, under which the company plans to roll out around 12 million smart meters across its franchise area over the next decade. Within the First Regulatory Period alone, Meralco targets the installation of more than three million smart meters over four years, allowing real-time monitoring of energy use, faster outage detection, and better service response.
To accelerate this effort, Meralco has partnered with Itron, Inc., an American technology firm specializing in energy and water resource management, to initially manage 73,000 smart meters in Metro Manila before expanding to other areas. It has also teamed up with Aclara Meters Philippines, Inc., a subsidiary of Hubbell Inc., to deploy another 72,000 smart meters as part of its modernization drive.
These smart metering initiatives will support the planned Grid-Edge Operations and Control Center, which is expected to complement Meralco’s existing System Control Center by bringing low-voltage situational awareness into day-to-day grid operations. Combined with a Distributed Energy Resources Management System, the new facility will allow more coordinated and proactive management of distributed energy resources, demand response programs, and other emerging grid services.
“These technologies are designed to enhance secondary network visibility, particularly as distributed energy resources, residential batteries, and electric vehicle charging stations continue to expand across the grid,” said Meralco Senior Vice President and Head of Networks Froilan J. Savet.
Meralco’s long-term plan also aligns with the government’s clean energy agenda. Proposed investments include wider renewable energy access and electrification initiatives such as affordable solar solutions for households and solar home systems for remote and environmentally protected communities. The company is likewise moving forward with fleet electrification and the deployment of electric vehicle charging infrastructure across its facilities in line with the Electric Vehicle Industry Development Act and national EV roadmap targets.
Supporting all these efforts are planned upgrades to information technology and cybersecurity systems, which have become increasingly critical as grid operations grow more digital, automated, and data-driven. For Meralco, these investments go beyond infrastructure—they are part of a larger effort to build a resilient, responsive, and future-ready power network that can sustain economic growth and improve the quality of life in the communities it serves.
“These investments are critical to Meralco’s mandate to deliver high-quality, reliable, and stable electricity service, enabling us to meet growing and evolving power requirements and support the country’s economic progress,” Valles said.
