Abstract

The smaller of the Maldivian outer islands are vulnerable to food shortages during rough seas, drought, epidemics and natural disasters, of which the recent tsunami is a dramatic example1. The stunting of children and adults from food shortages is common, and infant mortality rates are around 10 per thousand. Life expectancy in the islands is low, caused mainly by common infectious diseases. A United Nations survey indicates that the poor quality electricity supply in these islands contributes substantially to the population's vulnerability. Existing electricity supply on the smaller islands is usually provided by a private supplier or by the Island Development Committee. These enterprises are not effectively regulated, and their supply systems are under designed. Distribution cables are extended to new customers until the voltage at the customer premises falls below marginal usefulness. Diesel generators are always purchased second-hand, and are unreliable and inefficient. Under the existing technology and regulations these communities are unable to propose a financially viable undertaking with affordable tariffs and therefore are unable to obtain bank loans to finance a reliable electricity supply. In some cases, where island communities are able to raise money to establish a central electricity system, they cannot afford to maintain the system properly. This research project investigates several possible means of reducing the lifetime cost of providing electricity in these islands. The possibilities investigated are modifying conventional engineering design criteria to be more relevant to the needs of small poor islands, using digital instead of expensive analogue equipment for metering, protection, control and synchronization, and utilizing renewable energy, particularly solar and wind power in hybrid with diesel generators.
