Manila: A yellow alert was raised over the Visayas grid on Wednesday from 3 p.m. to 9 p.m. after several coal-fired power plants remained on forced outage, reducing available capacity amid high electricity demand. According to Philippines News Agency, the National Grid Corporation of the Philippines (NGCP) reported that available capacity was estimated at 2,431 megawatts (MW), while peak demand was projected to reach 2,373 MW. This situation leaves the grid without enough reserve to meet contingency requirements. The power plants on forced outage include Units 1 and 2 of Therma Visayas Inc., Unit 1 of Kepco SPC Power Corp., Unit 1 of Cebu Energy Development Corp., and the 82-MW Toledo Power Co. coal-fired plant. Additionally, more than 20 power plants have remained unavailable since 2021. In response to these outages, 13 other power plants are operating at derated capacities, resulting in a total capacity loss of about 1,081.5 MW. This has further strained the power supply situation in the region. Preparat ions are also underway for Tropical Storm Maymay, known internationally as Kujira. The NGCP has activated contingency measures to minimize the impact of the storm on transmission facilities in Luzon. The company has ensured the reliability of communication equipment, prepositioned repair materials and supplies, and deployed line crews to strategic locations for immediate restoration of damaged facilities. As per the Philippine Atmospheric, Geophysical and Astronomical Services Administration's 8 a.m. bulletin, the center of Maymay was located 170 kilometers west of Bacnotan, La Union. The storm is carrying maximum sustained winds of 65 km per hour near the center and gusts of up to 80 km per hour. Several areas in Luzon remained under Tropical Cyclone Wind Signal No. 2, indicating expected gale-force winds, while areas under Signal No. 1 may experience minimal to minor impacts.
