  1. Small Wind Systems in Village Power Applications Southwest Windpower, Inc. “Renewable energy made simple” Andrew Kruse

  2. Company Overview • Leading producer of 400-3,000 watt wind turbines • More than 70,000 wind turbines produced in the last 10 years • Distribution in 60 countries with product in over 130 countries • Production in 2004 will reach 8 MW of capacity (10,000 wind turbines) AIR – 400 Watt Whisper 900 Watt Whisper 1000 Watt Whisper 3000 Watt

  3. Future of Small Wind Product maturity is approached as the technology evolves to meet specific market criteria. As for wind it is cost of energy, convenience and low noise Scaled 3d prototype parts 2 KW - Prototype • Product design based on low cost of energy, reliability and minimal noise • Cost of energy US$.08-.10 kWh • Innovative alternators designed specifically for small wind systems • Every component is tooled for lowest part cost in mind • Engineering cost to develop: $2-3M • Tooling cost for production: $1-1.8M

  6. Why Small Wind?

  7. Wind and Solar are complementary AVERAGE MONTHLY WIND SPEED SUMMER WINTER SUMMER AVERAGE MONTHLY INSOLATION HOURS

  8. Example: Solar/wind mix for 4.6 kWh/day SystemOverlay the calculated Power Supply requirement onto the resource base, determine mix and add 20% for variability of resource. 4.6 kWh/day supply requirement + 20% kWh/d

  9. Typical Small Wind System Cost • 400 Watt System (40 kWh/mo – 5.4 m/s wind) – $500-800 USD • 1000 Watt System (200 kWh/mo – 5.4 m/s wind) - $2100-2900 USD • 3000 Watt System (500 kWh/mo – 5.4 m/s wind) - $6100-7500 USD The examples below include the cost of the wind turbine, tower, wiring and battery

  10. Example -1 Indonesia • Installed in 1998 – Winrock International • Each system consists of a 600 watt wind generator, tower, batteries and hardware • 2 – Solor Island • 8 – Sumba Island • 4 – Java Island • 2 – Flores Island • 17- Sabu Island • 2 – Lembata Island • Application – Battery Charging for lighting, television and refrigeration

  11. Indonesia Purpose of the system is battery charging for lighting and for office application e.g.: Computer, TV, Small Freezer, etc.

  12. Example -2 Sri Lanka 2004 - USAID Funded Project The island of Baththalangunduwa is a small, narrow sandy island approximately 4km long by ½ km wide, about 10km off the West coast of Sri Lanka. There are approximately 300 families living on the island, in self made housing with isolated kerosene or small PV generators for power, and no reticulated water, sewerage or health facilities.

  13. Installation of Wind Turbines The project was formulated by US Asia Environment Program (under US-AID) to develop basic lighting and services power for approximately 20 households. The project is set up and run as a privately contracted service, to provide a working economic model to be replicated for other groups of housing.

  14. Power Uses In addition to the 20 families that received lighting from the system, energy was used for the community theatre and health clinic Theatre Clinic

  15. Lessons Learned The greatest failure of past renewable energy systems was due to poor planning and implementation of programs along with little or no after installation service • Installation of 100% subsidized systems • No network of qualified installers • No follow-up maintenance of installed systems • No end user training program • Use of unqualified equipment • Too many “hands” equipment must pass through

  16. What Works An objective of electrifying rural areas is to enhance social benefits through lighting, education and health to minimize migration of the rural population to cities • Making technology affordable through a combination of subsidies and payment programs • Training, Education and establishment of qualified distributors • The establishment of laws that encourage the use of Renewables
