The National Grid Corporation of the Philippines (NGCP) issues a yellow alert for the Visayas grid from 6 p.m. to 7 p.m. on Friday, citing reduced electricity supply. NGCP says several generating units are unavailable, including Units 1 and 2 of Therma Visayas, Inc. (TVI), which remain unavailable during the period covered by the advisory. NGCP also reports that Unit 1 of Cebu Energy Development Corp., a 82-megawatt (MW) facility, is on forced outage, attributed to the grid’s operating and maintenance program (GOMP). The advisories describe a tight power situation affecting the region, which relies heavily on power imports from Luzon and Mindanao. One source notes that as of 8 a.m. the available capacity is 2,682 MW. Both accounts indicate the alert is temporary and linked to specific outages and maintenance-related constraints on key coal-fired generation in the Visayas.
