2004 - USAID Funded Project 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.

Installation of Wind TurbinesInstallation of Wind TurbinesThe 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 UsesIn addition to the 20 families that received lighting from the system, energy was used for the community theatre and health clinic
