Under a number of bilateral programmes, Finland has supported Vietnam in the development of key sectors, such as water and sanitation, forestry, and innovation. The Embassy of Finland in Hanoi has enjoyed a successful cooperation with Vietnam’s Institute of Energy. Together, we have carried out a comprehensive study mapping the potential for biomass as a source of renewable energy in Vietnam. Many specialists and researchers from the Institute have had in-depth and frequent exchanges with Finnish experts in the field of energy, and this study is another great example of the continuing collaboration between the two countries. As Vietnam is currently preparing its new plan to optimize the future energy mix, Finland is committed to supporting Vietnam in the energy transition towards a sustainable and reliable power system. A flexible source of power is one of the key factors for Vietnam to ensure national energy security for socio-economic growth, while prioritizing the development of renewable energy and gas to power generation, as aligned with Resolution 55 of the Vietnam’s Politburo on the orientation of the National Energy Development Strategy until 2030, with a vision to 2045.
