The knowledge and support technical assistance (TA), Mongolia: Smart Energy System for Mongolia, will support the country's energy policy to promote renewable energy power generation and to maintain the power grid stability in Mongolia through studies to transform the existing national power grid to a smart grid using innovative technologies and practices. The government of Mongolia aims to increase the share of renewable energy in total installed capacity in the country from around 12% in 2018 to 20% by 2023 and 30% by 2030 as per the State Policy on Energy, 2015–2030.1 The country’s electricity supply depends on imported power (20%) and on domestic power, which is mostly generated by coal. The power sector adopts a single-buyer model, where National Dispatching Center (NDC), an independent system operator, is the single buyer. Country’s renewable energy development has been supported by private sector. The government plans to transit from traditional power purchase agreement (PPA) scheme to auction system. To unlock the country’s renewable energy potential, Asian Development Bank (ADB) also supports the government.
