The Philippines is preparing for potential electricity
supply disruptions across Luzon, Visayas and Mindanao as a projected Super El
Niño threatens power generation and increases consumption toward the end of
2026.
Energy Secretary Sharon Garin warned on November 9 that
prolonged extreme heat could create significant pressure on the country's
electricity system. Higher temperatures are expected to push up household and
business consumption while reducing the efficiency and availability of several
power generation facilities.
The Department of Energy (DOE) expects the weather
phenomenon to reach its peak in late 2026 and continue into early 2027, raising
concerns about the country's ability to maintain sufficient electricity
reserves during the period.
Hydropower facilities face the greatest exposure, with
projected operating capacity falling to approximately 40%. Solar generation
could also be constrained to around 80% of its potential output. Conventional
power sources, including coal, natural gas and oil-fired plants, are not
entirely protected from weather-related disruptions.
The demand side presents another challenge. According to
Garin, every 1-degree Celsius increase in temperature could add approximately
100 megawatts to national electricity demand. This creates a difficult
operating environment in which power producers may have less electricity
available precisely when consumers need more.
Battery energy storage systems currently contribute only 253
megawatts of capacity, providing limited additional support for balancing
supply and demand.
Visayas Faces the Highest Projected Risk of Red Alerts
DOE projections indicate that all three major power grids
could experience critical supply conditions if additional generating capacity
is not secured.
The Visayas grid faces the possibility of four red alerts,
compared with one projected for Luzon and two for Mindanao.
A red alert is declared when available electricity cannot
adequately cover consumer demand and the operating reserves required to
maintain grid stability. Such conditions increase the possibility of rotational
brownouts and other service interruptions.
Yellow alerts could also become more frequent as generating
reserves diminish. Although less severe than red alerts, these warnings
indicate that the available reserve capacity is insufficient to meet
established requirements.
Garin acknowledged that the reliability of existing power
plants remains a significant concern. Aging facilities and generators that do
not consistently meet operational standards are more vulnerable to breakdowns
during periods of extreme heat.
Unscheduled outages could further reduce available
electricity, making supply projections less predictable. The DOE cannot
guarantee that all generating facilities will remain operational throughout the
anticipated El Niño period.
Government Seeks Additional Generating Capacity
To reduce the likelihood of electricity shortages, the DOE
is exploring temporary and standby power generation options, including
additional power barges and conventional plants that can be brought online when
necessary.
Garin said deploying power barges could take approximately
three months. The department is therefore coordinating with companies that own
available units within the country while assessing standby diesel and
coal-fired facilities.
The government is also conducting an inventory of potential
generating resources and engaging private-sector participants to identify
additional capacity.
These arrangements are intended to provide a contingency
buffer if actual electricity availability deteriorates beyond the department's
current forecasts.
The effectiveness of these preparations will depend on how
quickly additional facilities can be mobilized, their operational readiness and
whether sufficient fuel supplies are available when demand peaks.
Energy Security Risks Compound Existing Economic
Pressures
The anticipated power supply challenges come as the
Philippines continues to deal with higher energy costs linked to the conflict
in the Middle East. The country remains under a state of national energy
emergency, adding another layer of uncertainty to its energy outlook.
Rising energy expenses contributed to inflation reaching a
three-year high in October and placed additional pressure on economic growth
during the third quarter of 2026.
Weather conditions are creating a parallel concern. Dry
conditions are spreading across several parts of the country, with five
provinces already experiencing meteorological drought, 11 under dry spell
conditions and another 10 reporting dry conditions.
Reduced rainfall could further constrain hydropower
generation, potentially weakening an important component of the country's
electricity supply during the months when cooling demand is expected to
increase.
While Garin expressed confidence that the government is
preparing for the situation, the projected supply gaps highlight the importance
of securing backup generation before extreme conditions arrive.
The coming months will test the resilience of the Philippine power sector, particularly its ability to manage simultaneous increases in electricity consumption and reductions in generating capacity.
