Abstract Delay is a significant and versatile problem occurring in construction of large projects around the globe, and Indian hydropower projects are no exception to it. This study aims at to identify and rank the critical factors governing the delay in construction of hydropower projects in India. To this end, literature was reviewed comprehensively; interviews were conducted for preparation of an exhaustive questionnaire for major Indian Hydel executing agencies. In total, 96 significant causes of delay were identified. Applying the most widely used risk identification and ranking techniques, viz., Importance Index and Fuzzy Risk Assessment, the study revealed environmental clearance, geological adversities, local issues, R&R, land acquisition, contractual, cash flow, law and order issues as major delay factors. Software tools of Statistical Package for the Social Sciences (SPSS) and MATLAB were applied for data analysis. The study concluded that IMPI and Fuzzy Risk assessment were pragmatic tools for ranking of delay factors. The ranking results indicated that there is a significant relationship existing between the responses with no major difference in opinions of the expert belonging to owners and contractors. Finally, the study recommended measures to minimize and control these delays in hydropower construction projects, specifically in India.
