In this study, supportive leadership intervenes between critical success factors and sustainable project success. The study adopts a quantitative research approach using survey data from the project managers, project team leaders, and project staff of renewable energy projects. A questionnaire survey approach is used to collect data. For data analysis, we used the partial least square structural equation modeling through SmartPLS 3.2.2.

The outcomes also show that supportive leadership positively and significantly mediates between organizational, team and communication factors and sustainable project success. Meanwhile, supportive leadership negatively and insignificantly mediates between technical factors and sustainable project success.
