Northern Power Systems Technology Differentiation …Traditional Geared Turbine
Complex, high-speed (1800 rpm) drivetrain problematic:
5% DowntimeGearbox replacements every 5 years
Traditional Geared Turbine
Efficiency losses due to gear friction & electrically-powered magnetic field
Failures of large components require expensive crane & significant downtimecrane & significant downtime
NPS 2.3 PM/DD Turbine Simple, slow-speed (15-20 rpm) drivetrain extremely reliable:
2% DowntimeNo high-speed wear & tear, gearbox replacement
Very high-efficiency … no friction losses and permanent y g y pmagnets supply magnetic field
Highly modular design allows up-tower swap-outs: no crane & minimal downtime

Facilitates larger rotors
NPS PM/DD enables the Lowest Cost of Energy …Better Energy Capture via Very Large Rotors
Simple load path
Simple powertrain dynamics and harmonics
Better Energy Capture via Very Large Rotors
Simple blade characterization and construction
High efficiency power train and nacelle layout gives more power, especially at low wind speedsy
High Reliability Translates to Lower Operating Costs and RisksLow part count means fewer opportunities for failure
Highly modular design Enables tight quality control in productionUp-tower swap-outs: No external crane & minimal downtime
No oil or fluids to leak or change
Liquid cooling allows expanded environmental operating environment
