2 Something one must know about the scenario designing engineer Der Optimist denkt, das Glas ist halb voll. Der Pessimist glaubt, es ist halb leer. Der Ingenieur sagt, dass das Glas doppelt so groß ist, wie es sein müsste. Was nicht passt, wird passend gemacht! Dem Ingenieur ist nichts zu schwör! To the optimist, the glass is half full. To the pessimist, the glass is half empty. To the engineer, the glass is twice as big as it needs to be. What does not fit, is made to fit! Nothing to fear for an engineer! Engineers will most of the time try and find technical solutions for everything. They need to be encouraged to take into account societal aspects in technical system design! 2

9 Socio-technical energy scenarios for Europe (A4) Motivation European energy transition scenarios required for analysing effects on the German energy transition (power transmission, storage demand, power plant utilization) Compliance with societal norms Temporal, spatial and technological complexity Traditional scenario analysis using heuristics and intuition + - Scenario analysis using a specialised energy system model - + Combination of advantages and disadvantages!? Replacing intuition by context scenarios Coupling context descriptors and REMix energy system model parameters Consistent choice and quantification of base scenario, variable and independent parameters Consistent socio-technical scenarios 9

10 Socio-technical energy scenarios for Europe (A4) Base and variable model parameters Base parameters: represent descriptors with high socio-economic-political influence - Choice of descriptor futures according to the research question - Check in A2-context scenarios: is the combination of descriptor futures consistent? - Parameter quantification on the basis of descriptor futures and literature values RE-Shares high Adapted grid extension EU Renaissance Roadmap : 41,3% 2030: 51,2% 2050: 59,1% Ten Year Network Development Plan + Free Optimization from 2030 on Firm Capacity covered within Europe Variable parameters: high influence on the technical power system sensitivity analyses a) CO 2 -emission certificate prices b) fuel prices c) power demand 10

11 Socio-technical energy scenarios for Europe (A4) Sensitivity analyses Variable parameters and input data: Demand CO 2 certificate prices Fuel prices Results: - CO 2 certificate prices: only medium to high values according to context scenarios low influence on results - Fuel prices influence mainly the structure of power generation capacities - Power demand influences mainly the amount of capacity and system costs 11

13 Integrated scenario building on national scale (A2) Main objectives Analysing interrelationships between societal drivers and technological-structural development pathways required for the transformation of the energy system Constructing hybrid energy scenarios, which combine quantitative energy scenarios including infrastructural needs and consistent qualitative societal context scenarios Targets Premises Technologies Context scenario development - Data collection and evaluation - CIB-based construction of societal storylines - Quantification of storylines (Energy) Model based Analysis Identification of future infrastructure needs Markets Trends Existing infrastructures Integrated (hybrid) scenario building Consistent societal context scenarios Infrastructure needs (storages, grids...) Conclusions about pathways, risks & opportunities 13

14 Integrated scenario building on national scale (A2) Constructing context scenarios about the societal context of the Energiewende in Germany Data collection and evaluation Expert survey (n=28). 39 scenario factors ( descriptors ) identified in the fields of: International (e.g. European integration) Politics (e.g. planning legislation) Economy (e.g. GDP growth) Society (e.g. energy technology acceptance) Culture (e.g. value shift). Energy (e.g. energy efficiency in industry) 2-4 alternative futures assigned to each descriptor. Expert interviews (n=67, t=2h) about descriptor interdependences: 501 cross-impact statements => Qualitative impact network. Evaluating the impact network using CIB: 182 consistent scenarios out of configurations. Example of a cross-impact statement 501 CI statements CIB evaluation 182 scenarios 14

16 Integrated scenario building on national scale (A2) The energy system 2050: results for final energy demand & emissions: 3 examples of consistent scenarios with different societal pathways Final energy consumption (FEC) in PJ per year and CO 2 emissions in Mio t per year in Germany Market FEC residential (PJ/a) FEC industry (PJ/a) FEC services & commerce (PJ/a) FEC transport (PJ/a) Market CO2 emissions (Mt/a) The global market paradigm drives liberalization also in Germany. Materialism fosters an indifferent attitude towards the Energiewende. A strong economic development makes people ready to accept some burdens of the transition, however Stagnation FEC residential (PJ/a) FEC industry (PJ/a) FEC services & commerce (PJ/a) FEC transport (PJ/a) Stagnation CO2 emissions (Mt/a) Strong international conflicts, global fragmentation and high oil prices should motivate the society to transform. However, the pressure paralyses the country and makes it impossible for the society to take up the challenge. A weak economic development limits efficiency improvements and RE expansion The Power of the Center FEC residential (PJ/a) FEC industry (PJ/a) FEC services & commerce (PJ/a) FEC transport (PJ/a) The Power CO2 emissions of the (Mt/a) Center EU Renaissance promotes harmonized energy policies as well as economy. Moderate economic growth is sufficient for a neutral public attitude towards the Energiewende and high investments in efficiency and RE technologies. In addition, the emission effect of a strong economic development is avoided. (compare with Market ) 16
