The economic disparity between the National Capital Region (NCR) and the provinces is often measured in infrastructure. Last month, however, it was measured in kilowatts. While Luzon enjoyed a 34.2 percent drop in wholesale electricity prices in August, the Visayas and Mindanao regions faced an extraordinary price shock that exposed just how fragile the regional energy grid really is.
In the Visayas, spot market power prices jumped 64.9 percent last month to ₱18.59 per kilowatt-hour. In Mindanao, the spike was even worse, soaring 88.2 percent to ₱19.56. Data from the Independent Electricity Market Operator of the Philippines (IEMOP) shows these are the highest rates recorded since the wholesale electricity spot market began operating in those regions.
The immediate trigger was due to combination of thin margins and bad timing. Unexpected shutdowns at major power plants forced grid operators to run expensive backup generators to prevent widespread blackouts. Visayas registered its supply fall 2.6 percent to 2,201 megawatts against a hovering demand of 2,094 megawatts. That leaves almost no breathing room.
On the other hand, Mindanao faced its own 7.3 percent supply drop alongside a five percent demand increase, and sending power across the water to help Visayas only stretched its local grid further.
This is not due to bad luck or bad weather, but the direct result of delayed long-term planning. Building a power plant and connecting it to the transmission grid takes three to five years. The severe shortages hitting the central islands today stem from generation investments and line expansions that should have been locked in half a decade ago.
The Department of Energy (DOE) officials acknowledged as much, admitting that the government is now scrambling to catch up to demand that was easy to predict.
Today, the real-world costs are already hitting home. At a recent economic forum in Cebu, local business owners laid out what these daily disruptions mean on the ground.
Rotational brownouts force factories in industrial hubs like Mandaue City to stop assembly lines, reset sensitive equipment, and swallow higher operating expenses. While larger firms can afford to invest in solar arrays or alter work shifts to survive, smaller enterprises face immediate margin compression that threatens their survival.
Unreliable power also undermines regional efforts to attract foreign direct investment (FDI). Local governments can host international trade summits and pitch regional growth stories, but pitch decks do not mean much if the lights flicker out during the meeting. Foreign investors require basic utility security, not promises of relief years down the road.
Energy officials say immediate relief is on the way as six offline plants prepare to restart operations. Looking further ahead, the government points to new baseload and renewable projects secured through the Green Energy Auction Program, scheduled to come online between 2028 and 2031 for Cebu, Bohol, Panay, and Negros.
Yet, with El Niño threatening to dry up hydro reservoirs in the fourth quarter, waiting until 2028 is a tall order for businesses struggling to keep their doors open today.
To keep the Philippines’ southern economies moving, energy regulators, grid operators, and government agencies must stop working in silos. They need to clear regulatory backlogs, fast-track environmental clearances, and fix transmission bottlenecks that leave existing power stranded. Free market mechanisms are designed to price scarcity, but when prices stay this high for this long, they cease to be a signal and start acting as a tax on local enterprise. The country cannot afford a setup where Luzon enjoys cheap power while Visayas and Mindanao pay top peso just just to keep the lights on.
