Luzon and Visayas Power Grids on Yellow Alert Amid High Temperatures and Plant Outages

The Department of Energy (DOE) has reported that the extremely high temperatures in the Philippines have been affecting the operations of power plants, leading to the issuance of red and yellow alerts in the Luzon grid and a yellow alert in the Visayas grid. As of Tuesday, April 16, 2024, 31 power generation facilities have gone down, with a total capacity of 1,811.3 MW in the Luzon grid and 414.9 MW in the Visayas grid.

The DOE has asked the power plant operators to work on restoring full operations, and the agency will continue to monitor the situation. Meralco, the Manila Electric Company, did not resort to any manual load dropping due to the help of its big-load customers, which collectively de-loaded around 300 MW under the interruptible load program (ILP) .

The National Grid Corporation of the Philippines (NGCP) has declared Yellow and Red alerts for the Luzon and Visayas Power Grids due to unscheduled outages of some power plants. In Luzon, the DOE has ordered distribution utilities and electric cooperatives to implement their Interruptible Load Program to reduce overall demand on the grid. The DOE has also reminded government offices to conserve energy and minimize power usage during this period.

The Visayas Grid has also received a Yellow Alert notice due to outages and a decrease in the number of online generation facilities. Earlier, NGCP energized the 230 kilovolt (kV) Cebu-Negros-Panay Backbone Project Stage 3 (CNP3) to strengthen the transfer capacity from Panay to Negros and to Cebu, which is the final phase of the project.

Why this matters: The power supply issues in Luzon and Visayas have the potential to affect millions of Filipinos, as these regions are home to major cities and economic hubs. The government's response and the power sector's ability to restore stable supply will be essential in minimizing the impact on businesses and households.

The DOE has urged the public to maximize energy efficiency efforts and consider flexible work arrangements and other conservation measures during this period of extreme heat. "We are closely monitoring the situation and coordinating with the systems operator to ensure stability," said Energy Secretary Raphael Lotilla. The DOE and NGCP continue to work with power plant operators to restore full operations and prevent further outages as the country faces the challenges posed by the El Niño phenomenon .
