THE Luzon grid was placed anew on
yellow alert for 11 hours on Tuesday, the 48th this year.
Tuesday’s yellow alert happened due
to insufficient operating power reserve brought about by the forced outage of
several power plants.
Some of these power plants include
the San Buenaventura Power Ltd. (SBPL) coal plant, Quezon Power Ltd. coal
plant, AP Renewables Inc. geothermal plant unit 6, South Luzon Thermal Energy
Corp., GN Power Mariveles unit 2 coal plant and Prime Meridian Power Corp.
Avion natural gas plant unit 2.
These and some more plants that
experienced Outside-Management-Control outage contributed a total of 1,716
megawatts (MW) that were unavailable to the grid.
Moreover, there are seven power
plants—with a capacity of 2,176 MW—that are still on planned outage. These
are the coal plants of TeaM Energy Corp., Pagbilao Energy Inc., Masinloc Power
Partners Co. Ltd. and SEM-Calaca Power Corp.
The hydropower plant of CBK Power
Ltd., the geothermal power plant of AP Renewables Inc. and the combined-cycle
plant of Panasia Energy Inc. are also on planned outage.
Aside from the planned and unplanned
outage incidents, some power plants did not deliver their full capacity.
In all, 5,310 MW of capacity was
shaved off from the Luzon grid.
The Manila Electric Co. (Meralco)
said it has advised its ILP (Interruptible Load Program) participants to
deload, if needed.
“We are still waiting for ILP
participants to give feedback today, but yesterday [Monday], 104 accounts
confirmed availability to deload, equivalent to a deloading capacity of 213
MW,” said Meralco utility economics Head Lawrence Fernandez on Tuesday.
Last Monday, more than 4,500 MW
was shaved off from the Luzon grid, also for the same reasons.
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.
