Planned multifunctional projects on the Danube River 10 Ministry of Economy and Energy April 14, 2009
Planned multifunctional projects on the Danube River 11 Potential of the Danube River: Inland waterway navigation; Hydropower; Irrigation. Comprehensive utilization of this potential: Nikopol – Turnu Magurele Project; Calarasi – Silistra Project. Protection against erosion of the river course. Flood control. Ministry of Economy and Energy April 14, 2009
Planned multifunctional projects on the Danube River Inland waterway navigation: 12 EC declared the Rhine–Main–Danube Inland Waterway as Pan European Transport Corridor VII (TEN-T). Target: to become “the backbone of the waterway connection between Eastern and Western Europe”. TEN-T requires the elimination by 2015 of the existing bottlenecks, including the one of the reach between Bulgaria and Romania. Ministry of Economy and Energy April 14, 2009

Planned multifunctional projects on the Danube River Economic effect: 21 The Danube will be navigable at all times to provide reliable inland waterway from Black Sea to North Sea Production of electricity from renewable energy sources: more than 3800 GWh/year, about 10% of the gross electricity consumption in 2006. Two new railway, road, power transmission line, and telecommunication crossings. Improvement of the conditions for irrigation and water supply. Improvement of the conditions on the Bulgarian and Romanian riverbanks by reliable flood protection. Ministry of Economy and Energy April 14, 2009
Planned multifunctional projects on the Danube River Social effect: 22 New employment opportunities will be created for each of the two counties (Romania and Bulgaria) : • About 2300 work places during the construction period; and • About 850 permanent work places for qualified personnel during the operation period. Sustainable solution of the erosion problem of the Bulgarian riverbanks and the river islands. Improvement of the conditions for sport, tourism and fishing.

Conclusion Significant part of Bulgaria’s hydropower potential is still to be harnessed. Bulgaria is planning to develop: It is necessary to update the existing designs in order to: 23 Hydropower projects (Gorna Arda HPP, Yadenitsa HPP). Multifunctional projects (on the Danube River) Analyze in detail the technical, economical and environmental feasibility of the projects; Take into account the current conditions, as well as all the impacts from the projects implementation.
