Visayas, Mindanao Face Power Shortages Due to Coal Plant Outages

Consumers in the Visayas and Mindanao regions of the Philippines are bracing for potential widespread brownouts on Friday, September 4, as electricity supply remains severely strained due to ongoing outages at major coal-fired power plants. The National Grid Corporation of the Philippines (NGCP) has issued red alerts for both island groups. For the Visayas grid, a red alert is scheduled to be in effect for seven hours, from 3 p.m. to 10 p.m. A yellow alert will also be in place from 1 p.m. to 3 p.m., and again from 10 p.m. to 11 p.m. Mindanao, which typically supplements power to the Visayas grid, will also be under a red alert for an extended period, from 1 p.m. to 9 p.m. A yellow alert is slated for 10 a.m. to 1 p.m., and from 9 p.m. to 10 p.m. A yellow alert signifies that available power reserves are thinning, meaning any unexpected plant outage could trigger service interruptions. A red alert indicates that supply cannot meet demand, raising the risk of rotational brownouts unless consumption is managed effectively. The Department of Energy is intensifying efforts to add power capacity to these grids, including the deployment of battery energy storage systems and diesel power barges. However, the effectiveness of these short-term measures in fully alleviating the power deficit remains to be seen. The current power crunch highlights the vulnerability of the Philippines' energy infrastructure, its reliance on fossil fuels, and the slow pace of upgrading aging power facilities.
