Power supply alerts were raised over the Visayas grid after the region's electricity supply tightened, the Philippine News Agency reported on Wednesday.
The alerts drew a response from Iloilo, where a business group called for immediate government action on what it described as a power crisis in the Visayas, according to Inquirer.net. The province's governor also stressed the need for backup power and repairs to power plants, the Philippine News Agency reported.
The strain on the grid comes as the country's energy transition is being tested by supply gaps in the Visayas, SunStar reported.
Separately, Manila Bulletin reported that Department of Energy chief Garin is facing resignation calls and has left the decision on his stay in office to President Ferdinand Marcos Jr. The reporting did not state whether those calls are connected to the Visayas supply situation.
The reports did not specify the alert level raised, the length of the supply shortfall, or which plants were affected.
What to watch next: whether the Department of Energy issues details on the grid alerts and whether plant repairs or backup capacity are announced for the Visayas.
