Lyses onshore wind power projects

Applied for concession in 2007: 1,5 TWh

• Ulvarudla windfarm– 77 wind turbines

– 230 MW, 831 GWh

– Annual mean wind speed in hub-hight 9,6 m/s

– Existing 300 kV grid through the wind farm

• Brusali-Karten windfarm– 40 wind turbines

– 120 MW, 376 GWh

– Annual mean wind speed in hub-hight 8,8 m/s

• Skinansfjellet– Letter of intent with Norsk vindenergi

– 300 GWh

• Bjerkreim windfarm– Lyse has 14% ownership share (75 GWh)

NCS offshore wind

resources

• Average wind speeds up to >11 m/s at hub height (90m).

• Among the best wind-areas in the world.

• The wind at sea contains less turbulence compared to onshore locations.
