The Asian Development Bank (ADB) has been providing assistance to its developing member countries (DMCs) in the energy sector for the last 40 years, focusing on electricity sector expansion programs, interventions in the oil and gas sectors, institutional capacity building, and power sector reforms, governance, and efficiency improvement. ADB will aim to help DMCs to provide reliable, adequate, and affordable energy supplies for inclusive growth in a socially, economically, and environmentally sustainable way.
