This study evaluates low-carbon power pathways for Ghana using the CLEWs++ framework and OSeMOSYS. Accelerated solar PV deployment reduces cumulative natural gas generation and emissions by 12% relative to baseline, with only a 0.68% increase in costs. Nuclear power reduces baseload gas but requires higher investment. Policy recommendations prioritize large-scale solar and complementary nuclear in the long term.

📄 Abstract（原文）
Electricity generation in Ghana relies primarily on thermal energy, particularly natural gas for power production to meet the increasing demand. The dependence on thermal generation has improved energy supply but also increased greenhouse gases emissions. To support Ghana’s energy transition goals, this study assessed alternative low-carbon power production pathways using the Climate, Land, Energy and Water systems Plus (CLEWs++) framework in the Open-Source energy Modelling SYStem (OSeMOSYS) software. Four scenarios were considered: a Baseline representing existing policies, an Accelerated Solar Deployment scenario towards Ghana’s 26 GW of installed solar by 2040, a Restricted Solar Deployment Scenario and a Nuclear Power Development scenario introducing 1 GW of nuclear capacity from 2035 in line with Ghana’s plans. Electricity generation, natural gas utilization, carbon emissions and investment costs were used as indicators to assess the scenarios. The results show that the Accelerated Solar PV deployment scenario without any constraints on annual deployment rate reduces cumulative natural gas electricity generation by 12 % and emissions by 12 % relative to the baseline, with only 0.68% increase in cumulative costs. Restricting the deployment, on the other hand, increased natural gas use and emissions. The nuclear power inclusion reduced natural gas use as baseload, although it required higher cost investment than the Accelerated solar pathway. The study recommends that the Ghanaian Government prioritize large-scale solar PV deployment through supportive renewable energy policies, investment incentives and efficient transmission and grid infrastructure. Additionally, nuclear power should be pursued as a complementary strategy in the long-term to strengthen energy security and reduce emissions.
