Renewable energy auctions have become one of the most widely used policy mechanisms for procuring renewable electricity worldwide. In this episode, Diala Hawila, Team Lead on Renewable Energy Policy and Finance, and Hannah Sofia Guinto, Associate Programme Officer at IRENA, explore how auction design has shifted beyond achieving the lowest possible price to support grid integration, sustainable development and a just energy transition. They examine key design challenges, the objectives governments are embedding into auction frameworks and what countries and communities stand to gain from well-designed auctions.
