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


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
