Supergrid concept (Vision)
Main concept, combine:
Integration of renewable energy
Interconnections for trading
Security of supply
Benefits
Reduced investment
Increased trading capacity
Back-up power, e.g. hydro power
can support wind power
Large geographic area gives more
stable production

Task
Describe technology status
Describe ambitions towards an
off shore grid
Describe R&D challenges
Opportunities and Challenges
Opportunities:
Technology is available, no significant technology gaps
More compact HVDC solutions possible (reduced installed costs, 2 years to
develop)
Challenges:
Time (not long until 2020)
Projects take time, typically 5-8 years from concept to operation
Production limits
Cables
Get started!!!
Build additional production lines (3-5 years)
Engineering resources
Limited supply of qualified engineers
