4 The energy transition is transforming power generation Previously Power generation oriented towards consumption centers Today Nuclear energy is going offline step by step Wind energy is produced primarily in the north Solar energy is produced primarily in the south Conventional energy producers Load centers Wind energy Solar energy Partners for ULTRANET converters: Amprion GmbH / TransnetBW GmbH / Siemens AG Page 4

5 In the future current will have to cross distances >400 km Growing distances between electricity generation and consumption necessitate additions to the transmission network Three new transmission lines will be built in Germany With the converters for the ULTRANET network expansion project, Amprion, TransnetBW and Siemens are partnering to shape the energy transition ULTRANET Partners for ULTRANET converters: Amprion GmbH / TransnetBW GmbH / Siemens AG Page 5

6 Europe also needs new HVDC links Large-area balancing of local power surplus and deficits Reliable and economical longdistance transmission systems, e.g. for energy trading Moyle 2x250 MW Greenwire 1000 MW Western Link 2200 MW BritNed 1000 MW Biscay (Study) Caithness 1000 MW Eleclink 1000 MW NSN 1400 MW Cobra NEMO 700 MW 1000 MW INELFE 2 x 1000 MW Alegro 1000 MW Ultranet 2 x 1000 MW NordLink 1400 MW Piemonte-Savoie 2 x 600 MW South Westlink 1400 MW Storebaelt 600 MW EstLink MW Corridor A 1000 MW Corridor C Corridor D, 2000 MW EstLink 2 670MW COMETA 400 MW Sacoi-3, 400 MW Siemens participation Planned or third-party projects Partners for ULTRANET converters: Amprion GmbH / TransnetBW GmbH / Siemens AG Page 6

7 HVDC links a global issue Long-distance transmission E.g. Mundra-Haryana, India Bulk-power transmission E.g. Yunnan-Guangdong, China Island interconnections e.g. Australia-Tasmania Coupling of asynchronous systems e.g. Georgia-Turkey Grid access for offshore applications E.g. North Sea platforms DC for megacities E.g. Hudson, USA Energy trading e.g. Netherlands-UK Meshing direct current networks Partners for ULTRANET converters: Amprion GmbH / TransnetBW GmbH / Siemens AG Page 7

13 TransnetBW the company Employees: 580 (January 2016) Revenue: 5.9 billion (fiscal 2014) Wholly owned subsidiary of EnBW Energie Baden-Württemberg AG and certified independent transmission system operator Supply area: 34,600 km² Power circuit length: 3472 km Peak power in Baden-Württemberg: approx. 11 GW Electricity demand: max. 62 TWh Page 13

14 Energy transition - paradigm change The transition in figures: ~ 1.3 million prosumers in Germany THE TRANSITION IN FIGURES: ~ 1.3 MILLION PROSUMERS IN GERMANY 450 central power plants vs. 1.5 million distributed generation points Over 30% energy from renewable sources - three times as much as in 2000 and therefore much more volatile generation Spatial separation of generation and consumption, with most generation in the north and most consumption in the south Temporary reverse in power flow from lower to higher voltage level Loop flow in neighboring countries DIMENSIONS OF SUPPLY SECURITY National vs. European: Own production or copper plate? Integration of renewable energy System stability Page 14

15 Energy transition - supply security 2015: Redispatch in high wind (1) Germany s energy future... Long distances between generation and use Power transmission up to 800 km European internal electricity market and trading Large volume of fluctuating renewable generation BOTTLENECK... is already here! Page 15

16 Energy transition - supply security 2015: Redispatch in high wind (2) High wind situations and storm systems (like Niklas) currently lead to feeds of 30 GW (~ 85 % of installed capacity) from wind turbines. Already about 20% of this production has to be reallocated by the TSO. Market-related grid interventions are the order of the day. Source: TransnetBW Page 16
