MANILA, Philippines - Insufficient supply plagued the Luzon grid again yesterday as several power plants affected by the earthquakes over the weekend remained offline.
The National Grid Corp. of the Philippines (NGCP) raised the yellow alert from 10 a.m. to 11 a.m. and 1 p.m. to 3 p.m. as available capacity was only at 10,090 megawatts while peak demand was projected at 9,328 MW.
The Manila Electric Co. (Meralco) said power reserves were inadequate because the San Gabriel, San Lorenzo modules 50 and 60 as well as Avion 2 were not yet operational.
The Ilijan Block B, Pagbilao 2, Calaca 1 and Pagbilao 1 were also on scheduled forced outage yesterday.
Energy Undersecretary Felix Fuentebella said the Power Sector Assets and Liabilities Management Corp. started operating Malaya 1 and 2 to augment supply by 450 MW.
Meralco said 383 MW from Interruptible Load Program participants are also on standby.
The NGCP said normal power supply in the Luzon grid could be expected by next week as the operator of Ilijan Block B committed to supply 600 MW by Monday.
Fuentebella assured the public that the Department of Energy (DOE) would implement measures to prevent an increase in power rates in the electricity spot market.
“The DOE is in talks with the Energy Regulatory Commission and Philippine Electricity Market Corp. (PEMC) to…monitor and prevent price spikes brought about by the calamity,” he said.
The PEMC said rates in the spot market increased by as much as P10 per kilowatt-hour due to the supply shortage.
