Situated in the northeast of Quang Ninh province, Co To is one of biggest island districts in Vietnam. Lying 110 nautical miles to the Eastof Ha Long city and 50 nautical miles from the town of Van Don district presents the island with major problems in sourcing energy. With no national electricity network, the main electricity source on the island is diesel. The problems involved in turning diesel into electricity mean that only part of the demand for electrical energy on the island is met. Increasing demand for electricity for important activities such as production, socio-economic development and ensuring national defence and security is not beingreached. Therefore, research on technology solutions to supply the island district with more energy is an urgent technological and scientific task - and one which has great socio-political significance.
