Only the customers of the Luzon grid will continue to have uninterrupted power service today, the National Grid Corp. of the Philippines (NGCP) said.
Luzon grid, according to the NGCP, have enough reserves of around 223 MW today. First Gas Power Corporation’s Sta. Rita Modules 10, 20, 30 & 40, and San Lorenzo Units 50 & 60 are generating 252 MW each, totaling 1,512 MW contribution to the Luzon Grid.
This means that available capacity in the Luzon grid is higher at 7,170 MW as compared to the 6,947 MW peak demand.
Both Visayas and Midanao will continue to experience rotating brownouts.
In the Visayas, generation deficiency was placed at 30 MW after two units of Salcon Power Corporation’s Cebu Diesel Plant need to have an emergency shutdown which will cut around 10 MW from the Visayas grid’s available capacity.
The grid is expected to lose another 30 MW at 3pm from the shutdown of one unit of Cebu Thermal Plant, also owned by Salcon Power Corporation, resulting to up to 30 MW deficiency to the region.
Likewise, CE Casecnan Water and Energy Company’s Casecnan power plant, which was giving 65 MW is also down to 0 MW due to low water elevation.
Visayas has available capacity of 1,125 MW lower than the peak load of 1,155 MW.
The Mindanao grid will continue to suffer rotating brownouts after its generation deficiency increased again further to 748 MW today from the 700 MW generation deficiency recorded yesterday.
Mindanao has 772 MW available capacity compared to the 1,472 MW peak demand.
dThe NGCP maintained that the limited available capacities from National Power Corporation’s hydro power plants, most of which have water reservoirs that are drying up due to the El Niño dry spell is contributing to the power shortage.
Another factor that contributed to the increase in generation deficiency in the region is the emergency shutdown of Therma Marine 2 Unit 1 at 11:34 am today. The said plant which is owned and operated by Aboitiz Power has a capacity of 50 MW.
Water elevation of hydro power plants in Mindanao continues to be below critical level. Lake Lanao is at 699.02 meters, which is below the critical level of 699.15 meters. Pulangi elevation is at 283.9 meters. The peak demand for Mindanao today is 1,497 MW as against available capacity of 749 MW. (PNA)
