Key facts<br />

Population 34,206,710 1<br />

Area 2,376,000 km 2<br />

Climate The prevalent climate is hot and dry<br />

and there is an arid desert.<br />

Topography Generally flat, with featureless plains<br />

and desert dominating the north<br />

Rain Pattern The rainy season varies by region from<br />

April to November. 1<br />

Electricity sector overview<br />

Energy power infrastructure is at the moment<br />

developed only around selected urban centres and<br />

strongly associated with hydropower with limited<br />

thermal generation capacity. The national grid reaches a<br />

half million households, less than 10 per cent of the<br />

population; major and minor local grids serve another 5<br />

per cent. As a result, only 30 per cent of the population<br />

has access to electricity. 2 The National Electricity Utility<br />

(NEC) transmits electricity through two inter-connected<br />

electrical grids: the Blue Nile Grid and the Western Grid.<br />

The supply of electricity in off-grid zones is often based<br />

on small diesel-fired generators for power. 2<br />

The authors believed that there was a scope for<br />

extending the national electricity transmission and<br />

distribution capabilities, and that Sudan has the<br />

potential to engage in cooperative electricity<br />

transmission projects with neighbouring Ethiopia. 3<br />

Power generation capacity tripled in just a few years,<br />

rising from around 800 MW in 2005 to 2,687 MW in<br />

2007, with a shift toward hydropower (figure 1). 4<br />

The 2000 Energy Law opened doors to private investors<br />

in electricity generation, transportation and distribution.<br />

The 2001 Investment Law also did the same for foreign<br />

investments, inviting such cooperation in particular<br />

from China. 2<br />

Small hydropower overview and potential<br />

Before independence was granted to South Sudan,<br />

Sudan had the highest hydropower capacity in the North<br />

African region. 5 There are six hydropower plants in<br />

operation, with one of them being a small hydropower<br />

plant (below-10 MW installed capacity) (figure 2 and<br />

table). Sennar dam is the oldest dam in the country. 6<br />

There have been two agricultural projects, one in<br />

Eljazeera and one in Elmanagil, estimating the power<br />

generation potential for some irrigation structures. The<br />

Elzajeera project focused on the assessment of four<br />

different sites with a total estimated potential of 14.3<br />

MW. The Elmanagil project focused on the assessment<br />

of eight different sites with a total estimated potential<br />

of 12.66 MW. Potential sites for small hydropower<br />

plants are on existing irrigation dams and canals, as well<br />

as on seasonal rivers. 7<br />

The government is currently heightening the Roseires<br />

Dam by 10 metres, which will allow additional storage of<br />

4 billion m 3 of water. This water will be used to irrigate<br />

about 1.5 million hectares of land in the eastern part of<br />

the country which includes two schemes of Kenana and<br />

Rahad canals. Rough estimations indicate that each<br />

canal may provide 20 MW of small hydropower<br />

capacity.<br />

At the same time, two new dams are currently under<br />

construction at Upper Atbara and Setatit in eastern<br />

Sudan with a total capacity of 320 MW. The dams will<br />

also irrigate over one million hectares of land<br />

downstream and for that two giant canals will be<br />

constructed, each with one small hydropower plant with<br />

a capacity of 15 MW. Two Chinese companies, China<br />

Three Gorges Corporation (CTGC) and China Water and<br />

Electric Corporation (CWE), were contracted for the<br />
