This case study highlights MENTARI’s efforts and interventions to encourage project developers to mainstream gender and inclusion (G&I) in their renewable energy projects. Two project developers in the MENTARI pipeline, namely HDF Energy and Watala, have been aiming to integrate G&I into their companies and projects with MENTARI’s assistance. This study outlines some of the challenges they have encountered, the immediate changes that they have achieved and key ‘takeaways’ for relevant stakeholders, such as governments, development agencies and financiers that want to accelerate G&I integration in the renewable energy sector.
