Luzon grid supply stabilized; Visayas, Mindanao still critical
Tuguegarao City (March 23) -- Power transmission utility and system operator National Grid Corporation of the Philippines (NGCP) reports that the Luzon grid will have uninterrupted power today due to the availability of enough reserve of 773 MW.
Based on NGCP advisory emailed to this office, First Gas Power Corp.'s Sta. Rita unit 30 went online at 1708H yesterday and is now contributing 250 MW to the system. Natural gas supplier Malampaya Shell Philippines Exploration has completed its annual preventive maintenance works and is now supplying around 2,150 MW of power to natural gas plants.
Further boosting the available capacity are San Miguel Energy Corp.'s Limay combined cycle plant generating around 450 MW and various coal-fired power plants generating around 3,448 MW.
Plants with big capacities but are still offline are Sta. Rita unit 10 that has a capacity of 250 MW and Kepco Philippines Corp.'s Malaya unit 1 with a capacity of 300 MW and unit 2 with a capacity of 350 MW. Luzon is currently transporting 22 MW to the Visayas grid to augment the island's power deficiency.
The Visayas grid will still have power supply deficiency because of the unavailability of three power plants including the Cebu Diesel Power Plant which used to supply a total of 25 MW, Cebu Energy Development Corp. (CEDC) which used to generate 73 MW, and the Cebu Thermal Power Plant, owned and operated by Salcon Power Corp., which previously supplied 53 MW.
The Leyte Geothermal Power Plant (LGPP) unit 2, owned and operated by Green Core Power, went back online yesterday at 1616H. It is now generating 17 MW out of its total rated capacity of 32 MW.
Mindanao grid will continue to experience generation deficiency of 580 MW today which is lesser than yesterday's recorded figure. This can be attributed to the decrease in forecasted peak demand which is 1,386 MW today. Power deficiency in Mindanao is caused by the inadequate available capacities from the grid's main power sources -- National Power Corporation's hydro power plants Agus and Pulangi whose reservoirs are all drying up due to El Niņo.
