The Department of Energy’s (DOE) annual summer ritual is familiar: it promises that the electricity supply will be “enough and stable,” but the power grid clearly is not getting the memo.

After decades of forecasting, energy officials still miss the mark so consistently that it almost feels as if rotational blackouts—or brownouts—have already been built into the system’s expectations. Then, almost on cue, come the yellow and red alert declarations by system operator National Grid Corporation of the Philippines (NGCP), followed by the industry’s favorite encore: a noisy blame game while consumers are left sweating in the dark.

From Wednesday to Friday last week, while chaos was unfolding in the Senate, the country’s power grid staged its own national drama that forced Filipinos to endure rotational blackouts lasting up to three sweltering hours in some areas. For context, I prefer to use “blackouts” for consistency with global usage, although Filipinos more commonly refer to these incidents as brownouts.

Historically, summer in the Philippine power sector feels less like a season to be enjoyed and more like a nationwide suspense thriller, because consumers never know when the next blackouts and surging electricity bills will strike. But while Filipinos endured brutal summer heat without electricity, what made the blackouts even more infuriating was the flood of conflicting explanations from the industry and the government—as if coherent thinking and technical expertise were also on outage.

DOE pins blame first, questions later

From the DOE’s standpoint, the response came in a strongly worded directive ordering NGCP to fully disclose the back-to-back tripping of the 500-kV lines linking the massive Ilijan gas plants in Batangas.

According to the energy department, “the alert conditions were triggered by the tripping of the 500kV Ilijan-Dasmarinas transmission lines at approximately 6:00am on May 13, 2026, followed by the subsequent tripping of the 500kV Ilijan-Tayabas transmission lines,” adding that “the combined loss of these facilities resulted in the complete isolation of the Ilijan gas [plant] from the Luzon grid.” That prompted a cascading effect on the Visayas grid as well, since part of its power supply is directly imported from Luzon.

The department also primarily reprimanded NGCP for its “failure to promptly declare and report the Ilijan-Dasmarinas line trip to the relevant regulatory authorities at the time of the incident.” Therefore, it is now demanding the submission of a detailed report covering timelines, affected areas, plant outages, reserve levels, and restoration actions taken, among other details.

Nevertheless, what the DOE seemed to overlook is the critical technical core of the matter: the full sequence of events. A checklist-style report alone cannot reveal the real trigger of a grid failure.

To recall past blackout incidents, while a transmission line trip is often the effect, the cause sometimes stems from prior faults in other chains of the system—whether from power plants, switchyards, or other connection assets. This makes a full reconstruction of events essential to fairly determine what actually failed and who is truly at fault. Doing so will require more than a single account from NGCP; the DOE must also demand a complete causality chain report from the first plant that went offline. That way, the sequence of failures or system faults can be properly traced.

In fact, industry veterans and experts are now asking a pointed question: Does the DOE still have the technical depth to properly investigate and analyze complex faults in the country’s power system?

NGCP’s version of the blackout story

While Energy Secretary Sharon Garin quickly took to social media to fault the grid operator, saying there’s a “lack of supply because there’s a lack of grid,” NGCP itself had been in the media laying out a slightly different account of the situation.

NGCP claimed the tripped transmission line was restored, but Ilijan’s failure to re-synchronize back to the grid kept the system unstable, thus prolonging Luzon’s blackouts all the way to Friday.

Atty. Mutya Alabanza, the company’s spokesperson, narrated that the incident went beyond the Ilijan transmission line tripping. She noted that 31 power plants were on forced outages while others were running below capacity (de-rated).

However, the most striking statement in the narrative given by NGCP was this: several plants were also on "unplanned" maintenance shutdowns. Bluntly, that needs deeper scrutiny. The DOE must determine whether these plants were actually on unscheduled downtimes or merely suffered forced outages and failed to immediately resynchronize after the transmission line breakdown.

Instead of competing and confusing storylines from stakeholders and the government, what’s needed is a single steady hand to bring everyone to the table. The country needs a leader to clearly map out the root cause, the recovery hurdles, and the safeguards needed to prevent a repeat of this consumer-punishing grid disturbance.

It is obvious that leadership rests with the Energy Secretary, yet the real question is whether the DOE will fully uncover responsibility and impose meaningful penalties—especially in a system where consumers endure high bills and blackouts, but repeat offenders or habitually delinquent industry players often walk away unscathed.

Baseload capacity gap: Investment design flaw or policy neglect?

One key point raised by NGCP is the persistent lack of readily dispatchable baseload capacity, which leaves the grid exposed and far too fragile whenever a major plant suddenly goes on a forced outage. Baseload capacity refers to round-the-clock power generation that keeps the grid running continuously—an indispensable foundation for keeping the power system stable and reliable.

The DOE’s current planning direction is heavily tilted toward massive-scale variable or intermittent renewable energy investments, with its main policy engine being a series of green energy auctions (GEAs) across different RE technologies. For years, industry players have been cautioning the DOE about the urgent need for baseload capacity additions, yet current energy planning appears to be giving that concern far less attention than required.

While Secretary Garin is advancing nuclear to eventually replace coal's dominance in the baseload mix, that reality is still 10 to 15 years away. The core issue is simple: you cannot remedy a crisis that started yesterday with a solution that will only arrive a decade from now.

Even under a declared coal moratorium, already-approved coal projects are somehow finding a path to implementation. However, they are facing mounting resistance from environmental advocates and civil society groups, consequently hampering their advancement to the construction phase.

At this stage of grid unreliability, the DOE’s challenge is clear: secure firm baseload capacities and expand energy storage deployments if variable renewables are to be scaled aggressively without destabilizing the power system.

It is fair to note that solar plants helped cushion daytime demand and limit rotational brownouts, but the persistence of nighttime blackouts exposes a deeper gap: the absence of reliable, 24/7 baseload capacity.

The issue circles back to one fundamental question: Has the DOE efficiently planned for the country’s short-, medium-, and long-term energy needs, or is the recurring system instability proof that it has not? Truth be told, this cyclical summer mess points to a system that is clearly underprepared and mismanaged.
