• Energy efficiency gaining momentum
• Sector coupling + Energy Storage
• The energy system is getting more complex
• Digitalization is the key to handle the complexity and create new
customer value and profit pools / New business models emerging
• Technology / investment ↑ ➔ cost ↓ ➔ dynamics changes
• Need to manage the stranded fossil assets appropriately
• Geo-politics and governments play key roles
• More energy
• More affordable energy
• More affordable and safe energy
• More affordable, safe, and clean energy

Definition
• Link between power sector and energy-consuming sectors
• Crucial to reach deep decarbonization of the energy sector
(-80 … 95%)
Value Proposition
• Higher overall energy efficiency
• Supports supply/load balancing in case of high share
of intermittent renewable generation
• More diverse and interdependent energy supply
Drivers
• Reduction of GHG emission
• Energy efficiency improvement
• Reduction of energy import dependency
• Integration of volatile Renewables
• Technology development
(e.g. e-mobility, battery, hydrolyzer)
Sector Coupling

In a Sector Coupling approach, the increased
electrification reduces primary energy consumption
