Impacts of Solar Energy Policies on the Electricity Generation in Hunan, China

Abstract

This paper analyzed the changes in electricity generation in Hunan province under different solar energy policies. Three scenarios, namely baseline scenario (BAS), current policy scenario (CPS), and future policy scenario (FPS), were developed to represent various levels of solar energy development from 2021 to 2035. Utilizing the Low Emissions Analysis Platform (LEAP) model, the study assessed the impacts of these scenarios on the electricity generation mix, fossil fuel consumption, and the emissions of CO₂, SO₂, and PM2.5 in Hunan province. The results indicate that with the increase in solar energy generation, the electricity generation mix becomes more diversified, and the consumption of fossil fuels significantly decreases, along with notable reductions in CO₂, SO₂, and PM2.5 emissions. The introduction of solar energy as a clean energy source plays a crucial role in reducing dependence on traditional energy sources, mitigating environmental issues, and enhancing sustainability. Nonetheless, the research also highlighted issues in Hunan province, such as the uneven distribution of solar energy resources and inadequate supervision of the power grid. Consequently, this article proposed a range of policy suggestions. These included establishing upgraded power system to enhance grid infrastructure stability, reinforcing regulatory frameworks to tackle non-compliance, and adjusting financial assistance for solar power generation. The objective is to propel Hunan province towards a future characterized by sustainability and cleaner energy.
