1 RGI Workshop on The Need for Grids Why we need grids now Grid Planning - Carsten Siebels Hanover - 22nd of June 202 Overview. Current Situation at TenneT TSO GmbH 2. Decentralised renewable Generation 3. Offshore Development 4. Conclusion Why we need grids now June grid.eu

2 . Current Situation Situation 27th of May 202 Spring holiday with low demand in the night and moderate high generation from wind farms low demand in Germany approx MW Low demand all over Europe Yellow RAAS-traffic light from 05:30h to 08:00h: Extreme high voltage ( >420-kV ) in some substations Amprion GmbH TenneT TSO 50Hertz Transmission Mitigation measures for voltage control: Redispatch & use of all available shunts disconnection of 400 kv overhead lines TransnetBW 4 grid.eu 2

3 Situation 7th 4th of February 202 Winter with low temperatures, high load with low generation from RES Some thousand Megawatt of gas fired power plants not operating due to a lack of gas 50Hertz Transmission High Spot-Prices & high trading activity Amprion GmbH TenneT TSO German electricity balance timely with a lack of more than MW TransnetBW Critical situation: Activation of all available reserves - 30% Gas 5 Development of mitigation measures from year 2003 Year Quarter 202 Events* Days Events 43 Q4 585 Q Q 202 Year * Eventsfollowed by measures according 3 EnWG and EEG. 6 grid.eu 3

5 Decentralised Generation from Renewable Energy Sources (RES) - Example with 00 % supply of demand by RES RENEWABLE ENERGY (MW) A B Export of 200 % of current demand Import of 70 % of current demand Generation fits demand A B DEMAND (MW) no secure energy supply only by RES Export power exceeds maximum demand neighboured regions with same behavior will not balance the situation Need for Transmission-Grid Demand Generation HV line Transmission line Development in Germany - approx. 20 % supply from RES in 20 - RES-installation 20 with additional 2 % potential - scenarios 2022 with 40, 50 and 60 % supply by RES Stunde im Jahr grid.eu 5

7 4. Conclusion Conclusion. Necessary Grid Development - connection of Offshore Wind Farms - distribution grids (connection of decentralised power) - transmission grids (balance of RES, long distances) 2. Delayed grid development may result in - reduced security of supply - load shedding - costs for redispatch - TSO driven market intervention - RES power not usable Why we need grids now June grid.eu 7

8 Thank you for your attention TenneT ist nach dem Zusammenschluss mit transpower der erste grenzüberschreitende Übertragungsnetzbetreiber für Strom in Europa. Mit ungefähr Kilometern an Hoch- und Höchstspannungsleitungen und 36 Millionen Endverbrauchern in den Niederlanden und in Deutschland gehören wir zu den Top 5 der Netzbetreiber in Europa. Unser Fokus richtet sich auf die Entwicklung eines nordwesteuropäischen Energiemarktes und auf die Integration erneuerbarer Energie. werqweqwef Taking power further. grid.eu 8
