Key considerations• Demand response

– load shifting, load shedding…

• Trade between regions– Bottle necks and nested networks

• Distribution system and transmission system– Energy exports and/or balancing

• Linking sectors– Poly generation, Bio-refineries, EVs and PHEVs...

• Market design – “Low” electricity prices (RES support) vs High prices (ban of fossil)– Decreasing load hours thermal power plants

• What future?– Sweden/Nordic vs EU/Global

TWh

- Low EUA prices- No additional policy instruments- Low availability in non-renew(or phase-out)

- Very high EUA prices- Common EU renewable support- New non-renewable capacity- Declining demand

- Higher EUA prices- Renewable electricity targets

Including new interconnectors

Only existing interconnectors

The future for Sweden and the Nordic region depend on others
