Repurposing South Africa’s Retiring Coal-Fired Power Stations for Renewable Energy Generation: A Techno-Economic Analysis

South Africa is one of the most carbon-intensive economies in world, but it presently experiencing an energy crisis, as its utility company cannot meet country’s demands. The use renewable sources and retiring coal-fired power stations are two important ways alleviating this problem, well decarbonizing grid. Repurposing for generation (RCP-RES) while maintaining sustainability reliability has rarely been researched. This paper proposes macro- microelements repurposing Camden with aim improving through a low-carbon system. In model, concentrated solar (CSP) photovoltaics (SPV), combination storage technologies (STs), were employed RCP-RES, owing to their excellent levels availability fleet regions. simulation results show that densities CSP SPV significantly lower compared plant (CFPP). Both only able generate 8.4% 3.84% rated capacity retired CFPP, respectively. From economic perspective, levelized cost electricity (LCOE) analysis indicates cheaper than coal technology, even when considering
