Planned multifunctional projects on the Danube
River

• Inland waterway navigation
• EC declared the RhineMainDanube 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.

Planned multifunctional projects on the Danube
River

• Economic effect
• 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.

Conclusion

• Significant part of Bulgarias hydropower
  potential is still to be harnessed.
• Bulgaria is planning to develop
• Hydropower projects (Gorna Arda HPP, Yadenitsa
  HPP).
• Multifunctional projects (on the Danube River)?
• It is necessary to update the existing designs in
  order to
• 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.
