Sudan is one of the East Africa countries that have endured considerable economic strain with the loss of substantial oil following the separation of South Sudan in July 2011, but it is lucky enough to have an abundant solar energy potential resources with plenty of water resources and a large area of lands. River Nile State (RNS) one of Sudan states characterized by a huge potential of national resources. The location of RNS is covered by a Direct Normal Radiation above 1800 kWh/m/year, the resources available in the State is quite sufficient to support nexus between energy, food, water, and land use to offers an approach for multi-scale, integrated assessment of this nexus. The analysis and performance of the proposed parabolic trough power plant are done by using SAM software created by National Renewable Energy Laboratory’s (NREL) SAM software. The selected parabolic trough concentrated power plant system has a capacity of 100 MW nameplate capacity and 6 hours thermal Energy storage (TES). The simulation of solar energy potential contribution (quantity) and convenience (quality) of concentrated solar power (CSP) as alternative sources for the production of electricity in River Nile State. The annual electricity power generated for the 6 localities of River Nile State is calculated to be 389 GWh Abu Hamad, 381 GWh Atbra, 385 GWh Barbar, 383 GWh El Damer, El Matammah 364 GWh and 382 GWh Shendi respectively. For sustainability, the results show that fossil fuel can be the preserve considerably in this state and can achieve about 76 Million Cubic Meters of CO2 emissionreducing and 31 Million Cubic Meters Natural gas-saving with the line of the sustainable development program. For nexus issues, solar field area (land) is 587 acres with nonsolar field land area with a multiplier of 1.4 which gives a total plant area of 822 acres (8.22 acres per MW of power capacity) with Average solar radiation 2,587 Wh/m2/year. The energy outputs are: 562 GWh thermal annually (provided by solar radiation); and 389 electricity annually (produced by the plant) for Abu Hamad locality the higher solar potential resources, Besides a Total Annual Water usage is 84,238 m.
