OVER 5,000 megawatts (MW) was shaved
off from the Luzon grid Thursday because a number of power plants were still on
scheduled shutdown, forced outage and could not deliver their full output.
The total power generating capacity
unavailable to the grid stood at 5,310 MW. Of this, 2,176 MW was brought
about by planned outage, 1,716 MW from forced outage and 1,418MW from derated
plants.
This prompted the National Grid
Corp. of the Philippines (NGCP) to issue a yellow alert notice from 10:01 a.m.
to 12 noon, from 1:01 to 4 p.m.; and from 5:01 to 6 p.m. This is the fourth
consecutive day for the NGCP to issue a yellow alert notice.
The power plants that are on
scheduled shutdown are CBK Power hydro plant, Pagbilao coal plant, Sual
coal plant, SEM-Calaca coal plant, Panasia combined-cycle plant,
Masinloc power plant and the coal plant of South Luzon Thermal Energy Corp.
Those that went on forced outage
include San Buenaventura Power Ltd. (SBPL) coal plant; Quezon Power Ltd. coal
plant; Prime Meridian Power Corp. Avion natural gas plant unit 2; the gas plant
of Millennium Energy Inc.; AP Renewables Inc. Makban geothermal plant and GN
Power Mariveles coal plant.
A yellow alert is issued when
operating reserves have dropped below the required 647 MW contingency in Luzon,
or equivalent to the largest unit in Luzon, which is the 647-MW coal-fired
power plant in Sual, Pangasinan. The Manila Electric Co. has advised its
ILP (Interruptible Load Program) participants to deload, if needed.
