Grand Ethiopian Renaissance Dam on the initial storage in the Aswan High Dam and this filling schedule of the GERD, flows into Egypt could be temporarily reduced, which may affect the income of two million farmers during the period of filling the reservoir. Allegedly, it would also "affect Egypt's electricity supply by 25 to 40 percent, while the dam is being built". However, hydropower accounts for less than 12 percent of total electricity production in Egypt in 2010 (14 out of 121 billion kWh), so that a temporary reduction of 25 percent in hydropower production translates into an overall temporary reduction in Egyptian electricity
Aswan Dam exchange rate in 1970 of $2.30 per E£1): £140 million from agricultural production, £100 million from hydroelectric generation, £10 million from flood protection, and £5 million from improved navigation. At the time of its construction, total cost, including unspecified "subsidiary projects" and the extension of electric power lines, amounted to £450 million. Not taking into account the negative environmental and social effects of the dam, its costs are thus estimated to have been recovered within only two years. One observer notes: "The impacts of the Aswan High Dam (...) have been overwhelmingly positive. Although the Dam has contributed to some
