Visayas Grid Faces Yellow Alert on July 31 Due to Insufficient Operating Margin
The Visayas grid in the Philippines is expected to be placed under a yellow alert on the evening of Friday, July 31, 2026, signaling a potential power shortage. Reduced generation capacity is cited as the cause, potentially impacting the grid's ability to meet demand.
The National Grid Corporation of the Philippines (NGCP) announced that the Visayas grid will be placed under a yellow alert on Friday evening, July 31, 2026. The yellow alert is scheduled to be in effect from 6 to 7 p.m., according to the NGCP advisory. The NGCP said the available capacity of the grid is 2,564MW, but peak demand is estimated to be 2,321MW. "A yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement," it added. The company also said some plants are on forced outage or are running on derated capacities, as follows: These have resulted in having a total of 969MW unavailable to the grid, NGCP said. Visayas' large coal plants TVI 1&2 and CEDC 1 were also unavailable, while KSPC 1 had an emergency shutdown on Thursday, July 30 due to boiler tube leak, the company added. —KG, GMA News
