Consumers are facing a dual energy price shock this month as upward adjustments in generation charges and escalating geopolitical tensions in the Middle East drive up both household electricity rates and retail pump prices.

Manila Electric Co. (Meralco), the country’s largest power distributor, announced on Friday, July 10, an upward adjustment in its generation charges for July. The utility is raising electricity rates by ₱0.3428 per kilowatt-hour, bringing the overall tariff for a typical household to ₱14.8261 per kilowatt-hour from ₱14.4833 in June.

For a residential customer consuming 200 kilowatt-hours, the adjustment translates to an immediate ₱69 increase in their monthly bill.

Joe Zaldarriaga, Meralco spokesperson, said in a media briefing that the primary catalyst for the adjustment was the generation charge—the cost of purchasing power from suppliers—which climbed by ₱0.1800 per kilowatt-hour to ₱9.2504, largely due to elevated global fuel costs.

Supplies from First Gas/Prime CoreGen, which constituted Meralco’s most expensive source during the billing period, rose by ₱0.3613 to ₱10.6489 per kilowatt-hour. 

Unlike domestic gas, imported liquefied natural gas is subject to a 12 percent value-added tax, adding a ₱0.0960 per kilowatt-hour tax burden onto consumers. First Gas, Power Supply Agreements, and the spot market accounted for 22 percent, 72 percent, and 6 percent of Meralco’s grid requirements, respectively.

Simultaneously, the seasonal heat drove power demand on the main island of Luzon to an all-time high of 14,534 megawatts. The surging demand squeezed grid capacity, sending Wholesale Electricity Spot Market prices to ₱8.0337 per kilowatt-hour and forcing the grid operator to trigger secondary price caps 11.1 percent of the time.

Transmission and secondary charges also rose by ₱0.0668 per kilowatt-hour. The utility noted that the broader tariff spike was only slightly mitigated by the Energy Regulatory Commission’s decision to extend its suspension of the ₱0.0371 per kilowatt-hour Green Energy Auction Allowance until August 2026.

Meralco reiterated that pass-through generation and transmission fees are remitted directly to power producers and the grid operator, while its own distribution charge has remained frozen since August 2022.

Compounding the utility crunch, domestic transport costs are poised to jump. Retail fuel prices are projected to rise significantly, driven by a breakdown in security and diplomatic talks between the United States (US) and Iran.

Based on the four-day trading Mean of Platts Singapore, domestic diesel prices are expected to surge by ₱2 to ₱4 per liter, while gasoline prices could fluctuate by up to ₱1 per liter. The Department of Energy is scheduled to finalize the regulated price adjustments on Monday.

The global oil market has taken an aggressive upward turn following military exchanges in the Strait of Hormuz, where Iranian forces allegedly targeted commercial vessels, triggering US retaliatory strikes and the revocation of Washington's sanctions relief for Iranian oil exports.

Traders are pricing in prolonged supply disruptions, which are being exacerbated by falling Russian diesel exports following intensified Ukrainian drone strikes on oil refineries. While steady Asian demand briefly softened gasoline prices, energy analysts warn the relief will be short-lived as the Northern Hemisphere's peak summer driving season tightens global fuel inventories further.
