The Philippines is addressing high electricity costs, which reached PHP 12.43 per kilowatt-hour in June 2026, through a rapid expansion of rooftop solar installations and a push for nuclear energy. The government aims for a 35% renewable energy mix by 2030, while the House advances the PhilAtom Bill to establish a regulatory framework for nuclear projects.

This trend reflects a broader movement across Southeast Asia, where nations are integrating nuclear energy into decarbonization strategies to meet projected electricity demand growth. Countries such as Vietnam, Indonesia, and Malaysia are exploring or resuming nuclear projects to complement renewable energy. Meanwhile, in South Korea, the expansion of solar power is creating new challenges for grid stability, requiring more flexible power systems to balance intermittent solar generation with steady nuclear output.
