Despite the yellow and red alerts triggered on the Luzon grid on Monday, Department of Energy (DOE) Secretary Raphael Lotilla said there were no fuel supply constraints in the grid.
“We assure the public that the DoE is verifying the cause of the forced outages this morning as there do not appear to be any fuel supply constraints. A DOE team will perform actual physical spot checks and validate the status of affected transmission lines and power plants,” Lotilla said in a statement.
Earlier today, the National Grid Corporation of the Philippines (NGCP) placed the Luzon Grid on red alert from 1:00 p.m. to 4:00 p.m. and yellow alert from 9:00 a.m. to 1:00 p.m. and 4:00 p.m. to 9:00 a.m. :00 PM as seven power plants have been forced to shut down, while three others are operating with downgraded capacities.
3,627 megawatts (MW) were cut from the network following the alerts. NGCP data indicates that Luzon Grid’s available capacity is 10,727 MW while peak demand is 10,585 MW.
A yellow alert is declared on a network whenever power reserves fall below ideal levels. If the balance between supply and demand deteriorates and indicates a severe shortage of electricity, a red alert is declared, which can lead to rotating supply interruptions.
