Solar photovoltaic (PV) generation is significant in sustainability and transitioning from diesel to clean energy. Integrating solar photovoltaic (PV) generation into the distributed networks improves energy balance, pollution mitigation, and cost reduction. South Sudan is an African country with frequent power outages and a lack of load reliability. The country's electricity demand stands at 300MW, with an installed capacity of around 252.4M. The gap in installed capacity is due to insufficient funds to build new electricity facilities. Two power plants were constructed between 2019 and 2025. Ezra's diesel power plant, which had a capacity of 33 MW, was built in 2019, while two solar PV plants with a capacity of 20 MW were commissioned between 2023 and 2025. The two Juba Solar PV plants aim to increase the current installed capacity of 33 MW to 73 MW, contributing to economic growth and job opportunities. The electricity tariff will be reduced gradually as the wattage amount increases. The paper investigates the challenges of integrating the 33 MW Ezra Diesel Power, Ezra 20 MW Solar hybrid solution and 20 MW Nesitu Solar PV plant. Factors such as weather conditions, energy intermittency, and unequal load will be investigated. Inverters, energy storage systems, and sensors can stabilize the energy flow between PV solar panels and the grid. Ezra and Nesitu Power Plants case studies will be shared and discussed in detail. Integrating two solar PV plants will reduce dependency on thermal generation and promote renewable energy generation.
