This study is the last part of a series of Blue Energy. It focuses on the blue energy hot spots in Indonesia, and the cost-effective delivery strategy. It shows how much blue energy may be available, where and how it could be gathered, and where it could be used across Indonesia or through exports. The objectives are to support blue energy resource and infrastructure data, to strengthen the decision-making support fuction, and to utilise Aquatera’s global blue energy database and RADMAPP tool to build a blue energy development model and pathway for Indonesia.
