www.ippnw.de Energy Transition – Energiewende - in Germany
www.ippnw.de The German Energiewende Integrated policy framework which combines four objectives: - Combat climate change - Avoid nuclear risks - Improve energy security - Guarantee competiveness and growth (Source: Agora Energiewende – 12 insights on Germany‘s Energiewende)
www.ippnw.de Wind and Solar -The cheapest renewable energy sources -Weather dependent -Variable -Only capital expenditure
www.ippnw.de Energiewende Wind energy and solar photovoltaics form the backbone of the German Energiewende. - Relatively high capital costs, but no operating costs - Weather dependency, production electricity fluctuates rapidly - Flexibility - the new paradigm of the German power system - These characteristics are fundamentally different from those of coal and natural gas; they profoundly alter the energy system and energy market
www.ippnw.de Challenge: Balance demand and supply - Baseload power plants disappear altogether - Natural gas and coal operate only part time - Operation of combined heat-and-power and biomass plants according to electricity demand - Balance successfulusing national and (not yet) European grids, theyarecheaperthanstoragesystems - Low power generation costs (2015): prices - 6-9 cts€ /kWh for wind energy - 8-9 cts€/kWh for solar PV.

www.ippnw.de Solutions for flexibility challenge - Wind and PV power need to be expanded in tandem since they have mutually complementary features - The wind blows when the sun is not shining and vice versa - Integrate the heat sector, offers enormous potential for increasing system flexibility
www.ippnw.de Midterm solution combined heat and power plants - in the medium term, dual-mode heating systems, capable of using either fuel or electricity will be deployed; - over the longer term, integration will occur by using a common fuel – natural gas, biogas, or power-to-gas combined
