Construction schedule

• Length of construction period from notice to
  commence to water on unit 1 Sønnå H is estimated
  to be 2 years and 9 months. Succeeding this is a
  period with testing the installation, gates etc..
  Unit 2 follows approx. 1 month later.
• Sønnå L will be finished approx 1 month after
  Sønnå H unit 2.
• Dalvatn power station is planned to be on line
  before Sønnå H and L comes on line.
• The various transfere / headrace tunnels are
  planned to be finished as early as possible
  taking into consideration the limitation on
