Visayas under yellow alert from 6 to 9 p.m. on August 23 — NGCP
The Visayas power grid was placed under yellow alert on Sunday, August 23, following forced generator outages and derated plant capacities that took more than 900 megawatts (MW) offline.
The National Grid Corporation of the Philippines (NGCP) has issued a yellow alert for the Visayas power grid on Sunday, August 23. The alert, which will be in effect from 6 p.m. to 9 p.m., was declared due to forced generator outages and reduced plant capacities that took over 900 megawatts (MW) offline.
According to the NGCP, the yellow alert was triggered by the unavailability of two major coal-fired facilities, TVI Units 1 and 2, and the unexpected shutdown of KSPC Unit 1 on Saturday, August 22. These outages, along with forced outages at several other power plants, have significantly reduced the grid's capacity.
The NGCP reported that available grid capacity stands at 2,516 MW against a forecasted peak demand of 2,292 MW. The yellow alert was issued when operating margins fell below the transmission grid's required contingency reserves. This alert signifies a warning that the grid might face stress if demand increases.
