Description: A previous report (IRENA, 2017) examined longterm modelling and tools to expand variable renewable power in emerging economies. The present report complements that earlier work. It considers proven processes and regulatory practices for long-term power system planning, drawing primarily on experiences with integrated resource planning (IRP) from South Africa and regulated markets in the United States. Based on insights from those regulated markets, the study aims to guide power system planning processes and regulatory actions, with particular consideration given to ramping up solar and wind power, over the next few years.
