What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).

Storage hydropower Sudan

Roseires Dam, a concrete buttress dam located in the Blue Nile, was commissioned in 1966 to supply irrigation and domestic water, and generate power. By 2017 water for irrigation had yet to be supplied and construction to facilitate the supply was ongoing. The hydropower plant generates 1,800 GWh of energy. . The Blue Nile originates from the Ethiopian highlands with a catchment area of 254,230 km2 upstream of Roseires Dam (see Figure 2, “Rosaries. . The original Roseires reservoir volume in 1967 was 3.024 km3. By 2017, the approximate reservoir volume had reduced by 30percent, estimated as. . The dam was designed with the intent to sluice sediment on an annual basis. This is done by lowering the water surface elevation in the reservoir during the flood season with the minimum level being maintained at 467 masl between June 15 and September 15, and the reservoir refilled with water by November.

Why are there no reservoirs in Sudan?

Reservoirs in Sudan are small in storage capacity as compared to the other reservoirs in Ethiopia and Egypt. Due to that they cannot store water up to their full level in the dry seasons and there are fluctuations in energy production and reservoir water level.

What will happen to the energy production in Sudan?

The energy production in Sudan will increase by 39% due to the construction of a single reservoir in the Abbay River. There could be small energy reduction (up to 9%) at HAD due to reduced reservoir water level. There are also slight water loss changes in the whole Eastern Nile due to the implementation of reservoirs.

How does upper cascade development affect energy production in Sudan?

Generally there are positive impacts of upper cascade development for energy production in Sudan. Due to their less storage capacity, the energy production in the dry months is less but the upper cascade development can mitigate this problem. Fig. 9.
