The international competition is challenging Ø The industry is a moving circus (Andes/Rockies/Himalaya) -> The challenge to be local, but act global -> CSR/Compliance/Financing Ø An everyday world championship for best turbine efficiency -> At lowest price ! Ø The big bet for each competition -> How to pick the best partners and be the winning team *Lindeberg, NEF Teknisk Møte 2014

New challenges for the turbine manufacturers Low electricity prices • Changes in the • operations of the plants – Unbalanced power into the grid – Frequency Restoration Reserve (FRR) – Start/ stop *Lindeberg, NEF Teknisk Møte 2014

The winner takes it all-> must be best in class ! New calculation tools New production methods • • Dynamic stresses T-Blade francis – – runners Mechanical integrity – Cavitation – waterway –

Rainpower current R&D programs Robotic welding of Francis Runners q Energi X q Why do High Head Francis runners crack? – Basic models ready – Requires real time testing at power plants – Lifetime expectancy, project with Statkraft q Prediction models for lifetime of runners – Commercialisation in 2018 – Monitoring of turbine/generator/governor q OH YES-BIG DATA ! ü Connexi q New tech. platform for governor systems – In stock in 2017 –

High head Francis - HiFrancis Secure reliable operation • and lifetime for high head Francis turbines operating in the future energy market. Common R&D effort • – power utilities – Turbine manufacturers – Consultants – University Supported by government • funds source;: NTNU
