Study Insights
- Electricity demand in the Philippines grew by about 140% from 2003 to 2024, while transmission capacity expanded by only about 11%, highlighting the importance of how the system responds to rising demand.
- Delays in transmission projects, regulatory processes, and right-of-way constraints continue to affect investment timing.
- The study recommends strengthening regulatory incentives, improving institutional coordination, and supporting timely and efficient transmission investment.

Electricity demand in the Philippines has risen sharply over the past two decades, but how the power transmission system responds to this growth depends largely on regulatory design and institutional coordination, according to a study by the 蝌蚪传媒 (蝌蚪传媒).
Titled “The Need for Power Transmission Sector Reforms in the Philippines,” the study by 蝌蚪传媒 Senior Research Fellow Adoracion M. Navarro examines how regulatory frameworks, investment incentives, and coordination across agencies influence transmission sector performance.
While global energy tensions have brought renewed attention to power security, the study underscores that many of the sector’s challenges are structural and persist even in the absence of external shocks.
From 2003 to 2024, electricity consumption in the Philippines increased from 52,941 gigawatt-hours to 126,941 gigawatt-hours, an increase of about 140%.
Over the same period, transmission lines expanded from 20,774 circuit-kilometers to around 23,110 circuit-kilometers, or roughly 11%.
The study notes that this gap reflects how regulatory frameworks and institutional coordination influence the speed and efficiency with which the system responds to rising demand.
“This underinvestment in transmission contributed to the ongoing energy insecurity in the Philippines,” the study said.
The transmission sector plays a central role in delivering electricity from power plants to distribution utilities and large consumers.
In the Philippines, it operates under a hybrid structure, with government ownership of assets and private sector participation in operations, requiring clear regulatory oversight and coordination.
According to the study, delays in transmission projects remain a key issue. These delays are linked to a combination of regulatory processes, right-of-way constraints, and coordination challenges across institutions, which together affect investment timing and the system’s ability to keep pace with demand.
The study also highlights that delays in regulatory processes, particularly in rate-setting, can create uncertainty and influence investment decisions, with implications for both service delivery and cost outcomes.
“When transmission infrastructure is not available on time, lower-cost or cleaner generation gets curtailed, forcing the system to rely on more expensive alternatives,” the study said.
This illustrates how regulatory and coordination dynamics can translate into higher system costs, especially during periods of elevated fuel prices. However, the study emphasizes that these vulnerabilities stem from long-standing structural conditions.
To address these challenges, the study recommends strengthening regulatory incentives, improving coordination among institutions, and ensuring that investment and cost-recovery mechanisms support timely and efficient transmission development.
It also emphasizes the importance of streamlining processes for right-of-way and permitting, as well as enhancing regulatory capacity to support more predictable, transparent decision-making.
“Improving transmission sector performance will depend on regulatory capacity and clarity, effective coordination, and a governance framework that consistently prioritizes reliability, affordability, and long-term system resilience,” the study concluded.
The study positions transmission reform as a key part of building a power system that can respond to growing demand and evolving energy sources, while remaining resilient to both domestic and external pressures.
