The worldwide production of electricity undergoes dramatic changes in the recent years that had also tremendous impacts on the demands on hydro power. In the last years new experiences have been made in planning, fabrication and service of new plants. Especially also for existing pumping power schemes new service and operation modes are required. This has influence on the load profiles and dimensioning and life evaluation of the conduits.

The scope of the 3rd conference is to discuss the developments of the recent years as well as how to tackle the new challenges caused by the advanced operation modes on the

• concepts,

• design,

• materials and fabrication

for the conduits. This not only for the steel lining but also under consideration of the interaction between steel lining, concrete and rock. This requires new solutions far beyond actual standards and experiences.

The following items will be presented as invited as well as selected submitted individual contributions in the plenary session, followed by a discussion. In addition poster presentations are foreseen.

Topics:

1. Planning, potential, requirements, energy development, storage concepts: review, current situation, future prospects 2. Construction concepts for pressure tunnels (armored or unarmored) 3. Materials, joining and quality assurance 4. Steel construction, design, safety concepts, structural calculation 5. Safety and life cycle evaluation of existing plants

Site visit (20 September 2013):

Full day trip to Reisseck II pumped storage power plant by invitation of VERBUND Hydro Power AG.
