Driven by rising temperatures and increased use of cooling appliances, the Department of Energy (DOE) expects peak electricity demand this summer to surpass last year’s levels.

Latest DOE projections indicate Luzon’s peak demand could reach 14,769 megawatts (MW), up from 14,016 MW recorded on 22 April 2024. In the Visayas, demand is expected to rise to 3,111 MW from 2,641 MW on 21 May, while Mindanao’s peak could increase to 2,789 MW from 2,577 MW on 22 May.  

To ease pressure on the grid, new power projects under testing and commissioning are expected to add 1,890 MW in Luzon and 193 MW in the Visayas.

The Luzon-Visayas and Visayas-Mindanao high-voltage direct current interconnections will also improve supply availability, allowing capacity sharing of 250 MW and 450 MW, respectively.  

Meanwhile, the onset of La Niña may help moderate temperatures, while continued water releases from the Pantabangan and Magat dams are likely to support power generation in Luzon.  

To maintain grid stability, the DOE is urging households, businesses, and government offices to adopt demand-side management strategies, such as shifting high-energy activities away from peak hours — typically from 11:00 AM to 3:00 PM and 6:00 PM to 9:00 PM. 

The agency also advises consumers to set air conditioners between 24-26°C, use energy-efficient appliances, and maximize natural ventilation.  

“Without mindful consumption, this surge could strain the power grid, potentially leading to supply challenges and price fluctuations in the spot market,” Energy Secretary Raphael Perpetuo Lotilla said.  

“By making simple adjustments in daily routines, consumers can contribute to a more sustainable and efficient use of electricity, helping to prevent power interruptions and ensuring that energy resources remain sufficient throughout the summer season,” he added.
