Scenarios Differing in CO2 reduction
(80% vs. 90% to 1990)
Differing in RE supply and grid
infrastructures, driven by
exogenous domestic generation
share and option of endogenous
grid expansion

4. • Differences in input data cause significant deviations in some results
• Strong increase in power demand due to electrification of other sectors
• Wind and PV are main pillars of energy supply in 2050
• Increasing demand for back-up generation capacity

5. • Identical parameterization leads to approximation of results
• Considerable demand for temporal balancing on all time scales
• Demand flexibility of H2 electrolysis, electric heating and BEV charging can
complement and replace power transmission and storage
• Flexible sector integration particularly important when grid extension is limited

6. Disruptive elements – collection and evaluation
DLR.de • Chart 6
Collection of potentially disruptive elements
Definition: Disruptive elements are events that are a significant deviation from
current trends, and that have major impact on the energy system transformation
> IRENA/IEA Workshop „Understanding Innovation“ > Hans Christian Gils • Findings from the RegMex project > 9 November 2018
7. • Extremely fast implementation of Industry 4.0
• Massive cost reductions of decentralized storage
• Massive CCS cost reductions
• Smart Grid, Smart Markets, Smart Homes, Smart…
• Close to zero power costs, flat rate
• Electricity/energy autarchic buildings
• Increasing residential/commercial demand due to own production (3D printers)
• Break-through of completely new power generation technologies
Disruptive elements related to technology innovation

10. • In the optimization of transformation pathways with disruptions an approach
with partial foresight and rolling horizon appears most suited
• Potential combination with stochastic modelling approaches, e.g. focused on
technology innovation
Modelling disruptive elements – model horizon
DLR.de • Chart 10 > IRENA/IEA Workshop „Understanding Innovation“ > Hans Christian Gils • Findings from the RegMex project > 9 November 2018
11. • Almost all disruptions identified can be implemented in at least one model
• Mostly possible by adjustment of demand, cost or technology parameter
• Foresight over full planning horizon not compatible with analysis of disruptions
