Concentrating Solar Thermal power (CST) has a tremendous potential for scaling up renewable energy at the utility level, diversifying the generation portfolio mix, powering development, and mitigating climate change. This report: analyzes and draws lessons from the efforts of some developed countries and adapts them to the characteristics of developing economies; assesses the cost reduction potential and economic and financial affordability of various technologies in emerging markets; evaluates the potential for cost reduction and associated economic benefits derived from local manufacturing; and suggests ways to tailor bidding models and practices, bid selection criteria, and structures for power purchase agreements (PPAs) for CST projects in developing market conditions.
