Assessing the potential for solar power development for water supply projects in the Mekong Delta region

Abstract

The Mekong Delta (ĐBSCL) accounts for 12.3% of Vietnam's total area and has an urbanization rate of only 31%. In recent years, the region's water supply infrastructure has seen significant improvements, better meeting the growing needs of the population. At the same time, the Mekong Delta is witnessing a strong development of renewable energy, particularly solar power. Solar power projects for water supply facilities are considered to have great potential, with an estimated annual electricity output of 313 million kWh. These projects are not only financially viable, with an average payback period of approximately 7.56 years and an internal rate of return (IRR) of 13.68%, but also bring significant economic benefits and contribute to improving the quality of life for local communities.
