Why Small Wind?

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

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

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

Example -1 Indonesia Installed in 1998 – Winrock International 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

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

Example -2 Sri Lanka USAID Funded Project 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.

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.

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

Lessons Learned 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 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

What Works 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 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
