The cost-optimal capacity mix for 100% renewable electricity systems
The cost of renewable energy has decreased rapidly in recent years, making it the most affordable way to generate electricity in many parts of the world. At the same time, the need for radical reduction and even reversal of carbon emissions is driving cities, corporations and utilities to set ambitious targets for moving towards using 100% renewable energy.
From a power system design point of view, the shift from using large centralised thermal units to renewable, variable distributed units is challenging. This white paper examines the cost-optimal capacity mix and dispatch set-up for a 100% renewable energy sourced (RES) power system based on data from a country in central Europe and a country in west Africa that have different RES seasonality.
