comparing financing methods in energy projects based on istisna sukuk - blt contract and independent istisna sukuk annexation

one of the major problems for the implementation of infrastructure projects in various sectors of the economy, especially the energy sector, is the lack of liquidity. to solve this problem, project financing is created. bot contracts comprise one of the most common methods, particularly in infrastructure and energy sectors, and build-lease-transfer (blt) is a relatively new method of this approach. the operation of the contract faced some challenges because of legal problems in some of the blt contract's implementation. methods of project financing based on islamic contracts such as istisna sukuk independently or a combination of these methods with blt contract can be among operational techniques ahead which require comparative and combined research. the first step of this study is to gather experts' comments to determine the measures appropriate for the economic and energy project  situations in iran and then, based on these measures and ahp analysis, to rank independent istisna sukuk and istisna sukuk - blt contract annexation. the research findings show that istisna sukuk - blt contract annexation is appropriate for financing energy projects in iran.
