1 Rising to the Challenge - Renewable Energy Projects in the Arctic September 19, 2017 Einar M. Júlíusson, Project Manager lvpower.com

2 Key Takeaways Renewable energy solution can work anywhere Valuable lessons from overcoming challenges in Greenland Our lessons learned can be applied usefully elsewhere

3 Overview Landsvirkjun Power Introduction Hydropower case stories in Greenland Wind project in Iceland

4 Landsvirkjun Power offers hydro and geothermal advisory and co-development partnership solutions We provide advisory and co-development partnership solutions across hydro and geothermal power value chains Development, construction, operations, refurbishment Hydro and geothermal know-how is our solution base Feasibility studies Design and design reviews Tender preparation and execution Construction management and commissioning O&M reviews and refurbishment management We partner with experience to offer complete solutions Landsvirkjun power asset owner know-how is our core We partner with technical and financial services and will consider co-investment opportunities

5 Landsvirkjun Power is a subsidiary of Landsvirkjun, the National Power Company of Iceland Landsvirkjun key figures 2016 Financial figures in USD Hydropower stations Geothermal stations Wind turbines Capacity Output ~ 2,000 MW ~ 14 TWh Revenues EBITDA Profit Total Assets Liabilities Equity Ratio Credit Rating 420 m 302 m 118 m 4,3 m 2,4 m 45% Investment Grade

6 Hydropower development in Greenland and plants owned by Nukissiorfiit, the National Power Company 1993: Buksefjorden 3x15MW 230 GWh 2004: Tasiilaq 1,2 MW 6 GWh 2007: Qorlortorsuaq 2x3,8 NW 29 GWh 2009: Sisimiut 2x7,5 MW 58 GWh 2012: Ilulissat 3x7,5 MW 65 GWh Ilulissat 2012 Sisimiut 2009 Tasiilaq 2004 Buksefjorden 1993 Qorlortorsuaq 2007

7 Tasiilaq hydropower plant Serves a small community on the east coast Conventional small hydropower plant Challenge: electricity for a remote structure Construction: ÍSTAK Design of power plant: Mannvit

8 Environmentally friendly Micro-hydro used in stead of a diesel generator to power a remote control structure Water flow control structure needs electricity Diesel generator was the conventional solution Solution: Micro-hydro installed in the structure

9 Qorlortorsuaq hydropower plant Serves two communities in the south-west Conventional small hydropower plant Challenge: Transmission line with two fjord crossings Construction: ÍSTAK Design of power plant: Verkís Design of transmission line: Efla Design of fjord crossing: Mannvit

10 The conventional method to get transmission lines across fjords was used for one of the crossings The conventional method Floating a conductor 3 km across the fjord

11 The second fjord had some moving challenges

12 An innovative solution based on sound engineering and use of materials developed for the fishing industry Steel wire and pulley system with Dynex rope Conductors being pulled across 2 km

13 Working on transmission lines in Greenland is sometimes not for the faint of heart

14 Ilulissat hydropower plant Serves a community on the west coast Underground powerhouse Challenge: Permafrost Construction: ÍSTAK Design of power plant: Verkís Design of transmission: Efla

15 The layout of the facilities is conventional but the challenging permafrost conditions required new design

16 Successful computer modelling of permafrost and prediction of how rock temperature evolves with time

17 Design modifications in order to mitigate problems caused by the permafrost conditions Bypass on every turbine Outlet into the sea above sea level

18 Iceland s electricity and heat is 100% renewable Electricity generation 72% hydro 28% geothermal <0,1% wind Space heating 90% geothermal 10% renewable electricity

19 So, why wind energy research projects in Iceland? Strong and stable wind Conditions similar to offshore Operational experience needed Study effects of snow, ice, ash Integration of wind and hydro Social acceptance?

20 The results so far are quite promising 2x1 MW capacity since 2013 Capacity factor about 45% Reliable in arctic conditions Good integration with hydro Ongoing research and planning

21 Summary Renewable energy solution can work anywhere Valuable lessons from overcoming challenges in Greenland Our lessons learned can be applied usefully elsewhere
