Integrating Solar and Wind in Southeast Asia
…exposes countries to volatile fuel prices, potential supply disruptions and rising emissions. At the same time, the region possesses vast and diverse renewable resource potential. Variable renewable energy (VRE) - solar and wind - are now among the most cost-competitive generation options and are playing an increasingly important role in the region’s power sector. VRE presents an opportunity for the region to meet rising demand, support energy security, affordability and climate goals. However, integrating higher shares of VRE can present technical and regulatory challenges that require changes to system operation and planning. This report provides a comprehensive assessment of the…
