1 The Future of Wind for the Arctic Mark Peebles Business Development Manager Remote Communities

2 Energy Conditions in the Arctic Expensive power Challenging environment Universal problem 50% of arctic population live in isolated communities generating their own electricity Complex

3 EWT has proven track record of solutions that can work in Arctic environment Save communities ~ 1 m/year Expensive power Clean & reliable power Integration into micro grids Logistics experience Local BoP partners Challenging environment Universal problem Complex

4 What we do at EWT Best turbine in its class 250kw-1MW range Microgrid expertise Proven in challenging environment Commercial awareness

5 EWT turbine technology and product range LOADS LOGISTICS MAINTENANCE INTEGRATION Product range Component Technical Specifications 52/54/61m Drive system Design Generator synchronous, air-cooled, multi-pole, wound-rotor EWT designed Power converter Full-power, IGBT-controlled AC-DC-AC DW-52: 35/40/50m DW-54: 40/50/75m DW-61: 46/69m Control system Remote access Tower type Bachman PLC control system TCP / IP internet,dms 2.0 * SCADA Conical tubular steel, internal ascent

6 Technology Enhancements for Cold Climates Option Cold Climate Package Ice detection system Ice detection system Black blade coating Blade heating Description Extends operating range to -40 C Cold climate steel structural components Heating systems for drives & cabinets Arctic weather station components Coldstart-up controls Weidmüller BLADEcontrol integration Fast and reliable detection of ice on blades Customizable control logic TopWind IPS integration Atmospheric sensors detecting icing conditions Webcam with spotlight for remote inspection Passive de-icing Active de-icing Internal hot air heating Capable to operate during production Customizable control logic

7 Turbine installation process in a challenging environment 1. Transportation Component delivery 3. Component to site 4. Delivery and lifting of the first tower section onto the anchor Delivery and lifting of the third tower section onto the first 6. Lifting and installing the nacelle onto the top tower section 7. Lifting and installing generator onto the nacelle Lifting and installing the rotor 9. Turbine installed

8 Some project examples around the world Hybrid grid solutions Alaska Local industrial energy UK Wind Farms in China Remote community US Repowering Northern Ireland Self consumption Turkey

9 EWT solution in Alaska 4 x DW54 900kW 75HH turbines + diesel and storage 2 x DW52 900kW 50HH Cold climate (-40 C, north of the arctic circle) Highly challenging logistics overcome EWT technical solutions Active remote power control Delayed shutdown No actual earth connection (floating earth) Cold startup Automatic Power Frequency Voltage Control LVRT Kotzebue Commercial impact to 5 Communities 1 Community, 2 turbines: $~730k saved on average per annum reduction in CO2 emissions, saving 280,000 gallons of diesel a year Significant environmental impact Nome Bethel St Mary s Delta Junction

10 Alaska 2018 installation 2 turbines: DW52 900kW 50HH and DW54 900kW 50HH Interconnection Grid connection for 3 villages. EWT turbine connected to that grid Connecting in total 337 households / 1,495 population Objectives Replace ~206,000 gallons fuel/year Eliminate roughly 2,100 Metric tons of CO2/year Stabilize future energy costs Reduce risk of environmental damage
