    Increasing Penetration of Variable Renewable Energy: Lessons for Asia and the Pacific

    Variable renewable energy (VRE) technologies that harness solar, wind, and other intermittent energy resources are among the front runners for mitigating climate change. However, the timing and level of power generated from VRE installations depend on resource availability and are independent of the variations of power demand. VRE output is intermittent and comes with a low marginal cost. This unique combination of VRE characteristics will increasingly influence power system design, performance, and economics as VRE penetration increases.
