WHAT IT MEANS
- DOE’s Panay power supply plan adds 775MW of new generation to the region through 2030, with the earliest tranche landing only in 2028.
- Existing operators such as Therma Visayas, Panay Energy Development Corp, and GNPower Kauswagan hold the first position on restoration work and likely first position on the new contracts.
- Distribution utilities and industrial users in Iloilo and Western Visayas absorb the outage risk for at least two more years while the new capacity is built.
- The Mindoro-Panay Interconnection will eventually let Panay draw power from Luzon, which shifts pricing power away from Panay-based generators once it opens.
- Energy Secretary Sharon Garin has already said the buildout should have started five years ago, which puts real delivery risk on the 2028 to 2030 dates.
Panay’s power problem now has a paper trail. The Department of Energy laid out its Panay power supply plan on September 15, promising 775 megawatts of new generation through 2030 and a transmission link to Luzon that would finally end the island’s isolation on the grid. The announcement landed on the same day the National Grid Corporation of the Philippines put the Visayas grid under yellow and red alerts, with nearly 963 megawatts of capacity sitting offline from broken and derated plants. The timing was not a coincidence. It was the plan meeting the problem it was built to solve, in real time, on the same afternoon.
The Panay Power Supply Plan Adds Capacity In Three Stages
The Panay power supply plan splits new generation into dated tranches rather than a single project. Panay gets 135MW of baseload capacity by 2028, another 270MW in 2029, and 150MW in 2030. Alongside that, DOE is weighing 220MW to 440MW of gas-fired mid-merit capacity by 2028, pending investor commitments, to serve Panay and neighboring Negros through their shared transmission link. Combined at the low end, that is 775MW of new capacity arriving over four years.
| Capacity Tranche | Target Year | Type |
|---|---|---|
| 135MW | 2028 | Baseload |
| 270MW | 2029 | Baseload |
| 150MW | 2030 | Baseload |
| 220MW to 440MW | 2028 | Gas-fired mid-merit |
| 253MW | 2026 to 2028 | Ancillary services and battery storage |
Baseload plants run continuously and set the floor for supply. Mid-merit gas capacity fills the gaps when a major unit trips or renewable output drops. Together they form the backbone of the Panay power supply plan, but every megawatt in that table sits at least two years out. Nothing in the table addresses September 2026.
The Interconnection Changes Who Holds Pricing Power
The second half of the Panay power supply plan is the Mindoro-Panay Interconnection, which will physically connect the Visayas grid to the transmission link between Batangas and Mindoro. Once finished, Panay gains a second route to Luzon’s grid, on top of the existing Cebu-Negros-Panay backbone that already links it to the rest of the Visayas.
This is not simply a reliability upgrade. It changes who can sell power into Panay. Today, Panay-based generators hold a captive market. The island sits at the end of the Visayas transmission line, and outside supply during a shortage is limited to whatever the interregional links can carry. Once the interconnection opens, Luzon-based merchant plants gain a new addressable market on days when Panay is short, and Panay’s own generators lose some of the pricing power that comes from being the only game in town during a squeeze. Local operators who have quietly benefited from scarcity pricing during alert periods are looking at a longer runway before that changes, but the direction of the shift is now set.
Restoration Work Is Buying The Grid Time Now
While the dated tranches sit years out, DOE is leaning on plant restoration to get through the next few months. Forced-outage units at Therma Visayas, Panay Energy Development Corp, Therma South, and GNPower Kauswagan are scheduled to return between September and October 2026, aimed at rebuilding reserves before the next alert cycle. A medium-term layer adds 253MW of ancillary services, including battery storage spread across five Visayas provinces, to smooth over supply gaps while the permanent capacity comes online.
This restoration work carries its own exposure. The plants coming back online in September and October are units that failed once already this year, part of a pattern stretching back to a 260MW emergency scheme rolled out in June and a two to three day blackout history on Panay dating to 2023. Restoring a plant that already broke down is not the same as building new capacity that has never failed. The Panay power supply plan leans on both, but only one of the two carries a demonstrated failure record.
Existing Operators Hold The Early Advantage
The companies already running plants on Panay, Therma Visayas, Panay Energy Development Corp, Therma South, and GNPower Kauswagan, are the ones DOE is calling on to restore capacity right now. That gives them operational visibility and standing relationships with DOE and NGCP that newer entrants bidding for the 2028 to 2030 tranches will not have on day one. Whoever finishes construction fastest inside a grid this constrained gets first call on interconnection queue slots and contracting priority, and the companies already on the ground start that race ahead.
National Grid Corporation of the Philippines also gains ground here, regardless of which generator wins the new capacity contracts. Building the Mindoro-Panay Interconnection expands NGCP’s regulated transmission asset base, a position that strengthens whether the new baseload plants are built on time or not.
Iloilo Businesses Carry The Exposure Until 2028
The businesses that do not gain from any of this are the ones running on Panay’s grid today. Distribution utilities such as MORE Power and Panay Electric take the commercial and reputational hit every time NGCP calls a red alert, a shortfall that sits upstream in generation and transmission, well outside their control. Continuous-process operations in Iloilo, sugar milling, food processing, and export-oriented manufacturing, absorb direct production losses on alert days, and that exposure does not close until the first meaningful capacity lands in 2028 at the earliest.
For anyone weighing a facility, warehouse, or expansion decision in Western Visayas over the next two years, that exposure is no longer a guess. DOE just put dates on it. A site-selection committee evaluating Iloilo now has a documented, government-confirmed reliability gap to price into the decision, something that was previously an assumption rather than a published fact.
The Panay power supply plan does not compensate anyone for the intervening years. There is no rebate structure, no insurance mechanism, and no compensation clause tied to the alert schedule. The businesses absorbing red alert losses in 2026 and 2027 carry that cost on their own books while the capacity that would have prevented it is still under construction.
The Dates Carry Their Own Risk
Energy Secretary Sharon Garin has already undercut confidence in her own timeline. Presenting the plan, she said the buildout should have been in motion five years ago. That is not a minor aside. It is the official acknowledging that the region is years behind where it needed to be, from the department now asking the market to trust a fresh set of dates for 2028, 2029, and 2030.
The near-term measures, restoring forced-outage plants and deploying batteries, are the parts of the Panay power supply plan DOE can control directly through existing contracts and directives. The 2028 to 2030 tranches depend on private capital committing to construction timelines DOE cannot enforce past the terms of whatever contracts eventually get signed. A department that admits it missed its own window five years ago is not necessarily one whose next set of dates should be taken as fixed.
If any single tranche in the Panay power supply plan slips a year, the practical effect on Panay’s grid is another year of the same red and yellow alert pattern the region has lived with since 2023. There is no fallback layer built into the announcement for that scenario. The plan reads as sequential, not parallel, which means a delay in the 2028 baseload tranche pushes every date behind it as well, including the 2029 and 2030 additions that depend on the earlier infrastructure being in place first.
FAQs
What does the Panay power supply plan actually include?
It combines 775MW of new baseload and gas-fired mid-merit generation through 2030, the Mindoro-Panay Interconnection linking Panay to Luzon’s grid, and near-term measures including plant restoration and 253MW of battery storage and ancillary services.
When will Panay’s power supply actually improve?
DOE expects the region to become noticeably more stable by 2029, once the first two baseload tranches and the gas mid-merit capacity are online. The earliest new capacity under the Panay power supply plan arrives in 2028.
Who benefits most from the new capacity contracts?
Operators already running plants on Panay, including Therma Visayas, Panay Energy Development Corp, and GNPower Kauswagan, hold an early position through their restoration work and existing relationships with DOE and NGCP.
Does the interconnection lower electricity prices on Panay?
Not directly and not immediately. It gives Panay a second route to draw power from Luzon during shortages, which over time reduces the pricing power that comes from being an isolated market during supply squeezes.
Why does Garin’s five-year comment matter for investors?
It is the energy secretary acknowledging that the department’s own planning was late before this announcement, which is reason to treat the 2028 to 2030 delivery dates as commitments that depend on execution, not fixed outcomes.
Panay’s grid stays exposed through 2028 no matter how the new contracts get allocated. The operators already on the island move first into the coming capacity buildout, NGCP expands its transmission footprint either way, and the businesses running on Panay’s grid absorb two more years of a risk that now has a government date stamped on it. What shifts first is not the supply, it is who gets to plan around the shortage instead of reacting to it.
