2 New Innovations and Game Changers A panel debate Steffen Frydendal Poulsen, Siemens Gamesa Anders Rebsdorf, Envision Roel Schuring, LM Windpower Ignacio Marti, DTU Leo Enrico Jensen, DONG Energy Thomas Hjort, Vattenfall Henrik Fomsgaard Lynderup, Blue Power Partners With strong support Emilie Kærn, Implement Stiesdal A/S 2016, All Rights Reserved 2

3 The session concept It is really very simple No presentations from panel members A list of potential offshore innovations Discussion of viability and potential for savings or performance improvements But with a twist We calculate the impact on LCOE on the fly, using the Megavind LCOE tool Stiesdal A/S 2016, All Rights Reserved 3
