(without grid or cables)
The European Multi-area Power Market Simulator(EMPS)
Preliminary results:
 Increased exchange capacity
crucial to use available storage
 Surplus energy is used
 Reduced curtailment
 Increased prices in Norway
 More secure energy supply
 Reduced CO2 emissions
Current model:
• 55 areas in Europe
• 96 connections
• 15 offshore wind
areas
• 75 years of wind,
solar and hydro
resources simulated
• Start/stop nuclear
and pumping
handled

Impacts on fish ?
Erosion
Unsafe ice conditions ?
Threatening
biodiversity ?
More overhead

Collision risk for birds and
other wildlife impacts
Drawdown zone exposed

Social acceptance
Interviews of major stakeholders
- rules of the Norwegian Social Science Data Services

All stakeholders: Norway could help
reducing climate change by offering
balancing services from hydropower
Not realistic by 2020 political and
regulatory clarification
Limitations by environmental, commercial
and financial constraints or uncertainty
Existing grid policy major barrier
+ share benefits and costs from new cables
Better involvement of local communities
+ benefit sharing and change in current
legislation
Natural gas
Intergovernmental
agreements
 Long-term contracts
 Security of supply
(Germany)
 Security of income and
investment return
(Norway)

Why not the same for
exchange of renewable
energy ?????
Hydro and gas for balancing power
Timesteps
 Days and weeks

power)
 Day-night

 Spot marked

Why collaboration gas-hydro?
Demand for balancing and energy storage
 Market integration
 Regulatory and political issues
 Possibilities for Norway
 Learn from each other
Bring pieces to the table
- Put them together?
 Develop common scenarios
 Develop common case studies

Uncertain future – many scenarios
Rapid changes may come (…Fukoshima)
Hydro reservoirs = always an excellent energy storage
We probably need governmental agreements and new markets
Combined with other energy markets?
