IEA – Integrating Solar and Wind in Southeast Asia, 2025

The main theme of the report is assessing the readiness of Southeast Asia's energy sector to integrate higher shares of variable renewable energy (VRE), such as solar and wind power.

Key findings include: Southeast Asia is experiencing one of the fastest growth rates in electricity demand globally, with consumption expected to double by 2050. While renewable energy deployment has accelerated, the region's reliance on imported fossil fuels makes it vulnerable to fuel price fluctuations, potential supply disruptions, and increasing emissions. Variable renewable energy (VRE) is becoming one of the most cost-competitive generation options and plays an increasingly important role in the region's energy sector. Integrating higher shares of VRE may pose technical and regulatory challenges, requiring changes in system operations and planning. The report provides a comprehensive assessment of Southeast Asia's energy sector's readiness to integrate VRE, identifying opportunities and key aspects.
