Small Wind Systems Southwest Renewable Energy Conference Andy Kruse

What is Small Wind? 2 1MW – 3MW 100 KW 50 KW 10 KW2.4 KW Large Wind Small Wind Large wind systems: Typically non-distributed applications that sell bulk power to a utility or very large energy user Small wind systems: Exclusively distributed applications that produce energy for homes, farms, ranches, schools and factories (same as solar). Residential Wind

How They Work Typically do not use batteries (on-grid systems) Maintenance of modern wind turbines consists of annual inspection Installs in 2-3 days Most off-grid systems use both solar PV and wind 3 Off-grid system On-grid system

International Applications Indonesia Mongolia Bangladesh Dominican Republic Brazil

Grid Connected Applications Brownfield, Texas Oak Harbor, OH Kennebunkport, Maine New Jersey

Hybrid Street Lighting Parking Lot Integration Utility Power Pole Integration Commercial Applications

Remote Telecom Electrification (Canadian Bell - Canada) Island Diesel/wind hybrid systems (Maldives Islands) Micro-Grid and Industrial Applications Offshore platforms (Chevron – Gulf of Mexico) With the ever increasing cost of diesel, countries and corporations are turning to renewables, specifically small wind systems, in order to offset their consumption of petroleum. Small wind is easily adaptable to current existing systems

Modern Small Wind System Zig-bee wireless system communicates wirelessly from the wind turbine to your PC providing information on performance. Multi-piece mono-pole towers simplify installations 33’ 45’ and 70’ towers most common Wind turbines are fully integrated with minimal Maintenance requirements

Small Wind of Tomorrow The value proposition in small wind is not just about producing energy… Industry-wide decrease in COE by 70% over the next 4- 6 years (<$.08/kWh) Industry-wide turbine availability of >95% within the next 4-6 years Web-enabled auto-updates for performance optimization Smart grid support systems accessible by the utility Intelligent smart home system that allows the home to optimize power usage/net-metering credits Automated healthy monitoring systems that communicate with dealer to ensure Products that are optimized for lower winds (9-11 MPH) Features that allow for greater consumer interaction 12
