The Improving Energy Efficiency in Rural Areas of Vietnam measure included rehabilitating, modernising and expanding the rural electricity grids in northern, central and southern Vietnam. The three regional energy suppliers were responsible for its implementation. As part of the measure, low-voltage grids, medium-voltage grids, substations and transformers were installed in northern, southern and central Vietnam. As a result, the measure played a role in strengthening the Vietnamese distribution network by ensuring that rural areas were better connected to the national electricity grid.
