In March 2008, Egypt signed an agreement with Russia on the peaceful uses of nuclear energy. In 2015, contracts were signed with a Russian company to begin the building of the plant at El Dabaa. The current energy strategy in Egypt (adopted by the Supreme Council of Energy in February 2008) is to increase renewable energy generation up to 20% of the total mix by 2020. The majority of Egypt's electricity supply is generated from thermal and hydropower stations. The four main hydroelectric generating stations currently operating in Egypt are the Aswan Low Dam, the Esna Dam, the Aswan High Dam, and the Naga Hamady Barrages. The Asyut Barrage hydropower plant is scheduled to be commissioned and added as a fifth station in 2016. Almost all hydroelectric generation in Egypt comes from the Aswan High Dam. The Aswan High Dam has a theoretical generating capacity of 2.1GW; however, the dam is rarely able to operate at full design capacity due to low water levels. An ongoing refurbishment program is being enacted to not only increase the generating capacity of the dam to 2.4GW, but also extend the operational life of the turbines by about 40 years. In 2011, Egypt produced 156.6 TWh gross, of which 12.9 TWh came from hydroelectric generation. The per capita consumption of electricity at the end of 2012 was 1910 kWh/yr, while Egypt's hydropower potential in 2012 was about 3,664 MW. As of 2009-2013, hydropower made up about 12% of Egypt's total installed power generation capacity – a small decline from 2006-2007 when hydropower made up about 12.8%. The percentage of hydropower energy is steadily declining due to all major conventional hydropower sites already having been developed with a limited potential for further increase in generating capacity. Outside of the Aswan High Dam, the other hydropower sites are considered very modest and most new generation plants being built in Egypt are based on fossil fuels. Even with the addition of the Asyut Barrage hydropower plant in 2016, hydropower development in Egypt is still lagging as the existing and developed hydropower plants are no longer being constructed at a rate that can support the increasing electricity consumption in Egypt. The population of Egypt has increased by 14.3% in the five-year period from 2004 to 2009 (OECD/World Bank). Every six months there are 1 million more Egyptians. Energy production grew by 36% between 2004 and 2009.
