The Department of Energy (DOE) urged the public to adopt energy efficiency measures as rising temperatures increase electricity demand at the start of hot dry months.
Energy Secretary Raphael Lotilla warned that increased use of cooling appliances like air conditioners and refrigerators could strain the power grid, potentially leading to supply challenges and price fluctuations.
“Without mindful consumption, this surge could strain the power grid, potentially leading to supply challenges and price fluctuations in the spot market,” Lotilla said in a statement.
The DOE advised households, businesses and government institutions to implement demand-side management strategies, including avoiding or rescheduling high-energy activities during peak hours.
Peak hours are typically 11 a.m. to 3 p.m. and 6 p.m. to 9 p.m. on weekdays in Luzon, and the same daytime hours with evening hours in Visayas and Mindanao.
The department recommended setting air conditioners to 24 to 26°C, using fans, maximizing natural ventilation and maintaining appliances for efficiency. It also suggested inverter-type appliances for new purchases.
Businesses were advised to maintain equipment, adopt LED lighting and automated energy management systems, and implement demand-side strategies such as shifting energy-intensive operations to off-peak hours and integrating renewable energy.
Government offices were urged to maintain air conditioner thermostats at 24°C, limit operating hours, encourage stair use, turn off lights and computers during breaks and avoid high-energy devices.
The DOE said these measures would enhance grid stability, reduce costs and support long-term energy security.
