The value of dispatchability of CSP plants in the electricity systems of Morocco and Algeria

This paper examines the effects of an increased integration of concentrated solar power (CSP) into the conventional electricity systems of Morocco and Algeria. A cost‐minimizing linear optimization tool was used to calculate the best CSP plant configuration for Morocco's coal‐dominated power system as well as for Algeria, where flexible gas‐fired power plants prevail. The results demonstrate that in both North African countries, storage‐based CSP plants offer significant economic advantages over non‐storage, low‐dispatchable CSP configurations. However, in a generalized renewable integration scenario, where CSP has to compete with other renewable generation technologies, like wind or photovoltaic (PV) power, it was found that the cost advantages of dispatchability only justify CSP investments when a relatively high renewable penetration is targeted in the electricity mix.
