“We are closely monitoring the situation and will give updates as soon as available. Meanwhile, we are ready in the event the implementation of manual load dropping (MLD) or rotating power interruptions will be needed as part of our responsibility to manage the system,” Meralco said.

The NGCP also placed the Luzon grid on yellow alert from 1pm to 2pm, 4pm to 6pm and 9pm to 11pm.

The NGCP placed the Visayas grid  on yellow alert from 2pm to 4pm and 6pm to 7pm. Available capacity in the Visayas grid was at 2,742MW versus peak demand of 2,440MW. It said 12 power plants are on forced outage, while five  others are running on derated capacities, for a total of 676.5MW unavailable to the grid.

The NGCP said Tuesday afternoon it may implement MLD that would result to outages in several areas in  in five areas  to maintain the integrity of the power system.

It said it will implement MLD from 2pm to 3pmin the franchise area of Ilocos Norte Electric Cooperative affecting parts of Ilocos Norte), Isabela 1 Electric Cooperative (parts of Isabela),  Olongapo Electricity Distribution Company, Inc.

Meanwhile, the Department of Energy (DOE), through its Electric Power Industry Management Bureau  (EPIMB) said it is closely monitoring and coordinating with the NGCP and all generation companies on the current power supply condition following the red and yellow alert declarations.

The DOE has instructed all distribution utilities (DUs) in Luzon, including the Manila Electric  Co. (Meralco) and electric cooperatives (ECs), to activate their Interruptible Load  Program (ILP) to help reduce the overall demand in the grid. 

It reiterated the directive of President Ferdinand Marcos Jr. for all government offices to take the lead in conserving energy and minimizing power use, particularly during this period. 

The DOE is also encouraging the public to minimize the use of electricity during peak hours. These include  turning off lights and unplugging appliances when not in use, avoiding whenever possible, the  use of high-energy consuming devices such aircons and elevators.
