The Department of Energy (DOE) is closely monitoring and coordinating with the National Grid  Corporation of the Philippines (NGCP), generation companies, and distribution utilities to ensure the availability of power supply in meeting the power demand in view of the declaration of Red and Yellow Alert status in the Luzon and Visayas Grid.

The tight power supply conditions have persisted due to the sustained high peak demands in both the Luzon and Visayas Grids. According to forecasts from the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), certain areas continue to experience extreme temperatures and high heat indices. 

Notably, the actual peak energy demand for Luzon has surpassed forecasts in this El Niño year. 

Last 24 April 2024, the peak demand reached 14,016 MW, higher than the forecasted peak demand for the year of 13,917 MW. 

The DOE has identified a strong correlation of 93 percent between peak demand and heat index in Luzon. With the PAGASA projection of the heat index remaining elevated in select areas, the peak demand will likely remain above forecasted levels throughout the remainder of May.
