Overview
The High Dam is a 2,100 MW hydroelectric power plant in Egypt, one of the largest hydropower facilities in Africa. It plays a critical role in the country's power grid and water management.
The High Dam is a major hydroelectric power plant located in Egypt, with a capacity of 2,100 MW. It is one of the largest hydropower facilities in Africa and a cornerstone of Egypt's electricity generation. The plant is situated on the Nile River near Aswan, and its construction created Lake Nasser, one of the world's largest artificial lakes. As a hydroelectric facility, the High Dam uses renewable water resources to generate electricity, producing no direct CO2, SOx, or NOx emissions. The plant's technology is conventional for large-scale hydropower, with turbines driven by the flow of water from the reservoir. The dam also provides flood control, irrigation, and water supply benefits to the region. The High Dam is operated under Egyptian national regulations and is a key asset for meeting the country's growing energy demand. Its large capacity supports grid stability and reduces reliance on fossil fuels. The plant's environmental impact includes changes to downstream river flow and sediment transport, but it remains a vital component of Egypt's energy infrastructure.
Environmental context
The High Dam's hydroelectric generation avoids the air emissions associated with fossil fuel plants, contributing to improved local air quality. However, the dam and its reservoir have altered the natural flow of the Nile, affecting downstream ecosystems and sediment distribution. The large water surface area also leads to evaporation losses in the arid climate. Proximity to populated areas is limited, with the nearest major city being Aswan, approximately 13 km away.
Frequently asked questions
The High Dam is located on the Nile River near Aswan, Egypt. Its coordinates are approximately 23.97° N, 32.88° E.
The High Dam has a capacity of 2,100 megawatts (MW), making it one of the largest hydroelectric plants in Africa.
The High Dam generates electricity using hydroelectric turbines. Water from the Nile is stored in Lake Nasser and released through the dam to spin turbines connected to generators.
Hydroelectric plants in Egypt are subject to national environmental laws, including requirements for environmental impact assessments and water resource management. The High Dam operates under permits that address water flow, sediment management, and ecosystem protection.
The High Dam provides a significant portion of Egypt's electricity, supporting grid stability and reducing reliance on fossil fuels. It also supplies water for irrigation and flood control.
