The impact of coal to nuclear on regional energy system

With increasing global concern about climate change, many countries are actively seeking alternatives to traditional high-carbon energy sources. This study aims to explore the impact of repurposing coal-fired power plants to nuclear power plants (C2N) to regional energy system. The energy system in Guangdong Province in China is selected as an example. The impact of C2N on the energy system of Guangdong province is analyzed through three different hypothetical scenarios. Sensitivity analysis of the installed capacity of various clean energy sources in Guangdong Province is conducted to explore the optimal development range of installed capacity for clean energy sources in the energy system by 2030. The results show that the energy system of Guangdong Province can achieve near self-sufficiency in 2060 in certain scenarios. An increase in the installed capacity of nuclear power can reduce fuel consumption, overall costs, and carbon dioxide emissions effectively. C2N is significant in reducing carbon emissions, providing reliable power supply, and promoting sustainable development.
