Around　the　globe,　investment　in　renewable　energy　projects　has　been　increased　significantly　since　the　last　decade.　However,　recent　trends　of　completed　renewable　energy　projects　are　not　positive　enough　regarding　the　significantly　contributing　through　their　operational　performance.　This　study　is　an　attempt　to　figure　out　the　role　of　financial　and　non-financial　measures　for　the　performance　of　renewable　energy　projects.　A　sample　of　272x　respondents　was　collected　from　the　key　project　personnel　in　a　view　to　assessing　the　influencing　mechanisms　of　financial　and　non-financial　performance　measures　toward　success　in　renewable　energy　projects.　The　data　was　collected　through　a　convenient　survey　method　from　the　employees　working　on　managerial　and　technical　positions　in　the　small　and　medium-sized　renewable　energy　projects　in　Pakistan.　Structural　equation　modeling　(SEM)　was　used　to　perform　data　analysis　and　draw　inferences.　It　was　found　that　the　success　of　renewable　energy　projects　is　largely　depending　on　the　influences　of　both　financial　and　non-financial　performance　measures.　Moreover,　both　the　financial　and　non-financial　performance　measures　were　also　found　to　be　interlinked　with　each　other　positively　and　significantly.　In　addition,　the　role　of　financial　performance　measure　compares　to　non-financial　performance　measure　was　found　to　be　more　significant　while　contributing　toward　project　success　in　renewable　energy　projects.　The　results　also　show　that　both　the　financial　and　non-financial　performance　measures　function　as　complements　instead　of　substitute,　while　contributing　toward　renewable　energy　project　success.　Despite　the　role　of　financial　measure　is　higher　in　contributing　to　project　success　as　compare　to　non-financial　performance　measure,　ultimately　both　measures　are　necessary　for　sustainable　project　success　in　renewable　energy　projects.　The　research　findings　provide　new　insights　for　governments,　policymakers,　investors,　and　key　stakeholders　working　on　renewable　energy　projects　to　understand　the　measures　driving　better　performance　in　such　projects,　alongside　adding　a　knowledge　base　for　future　researchers　and　practitioners.　©　2020　ERP　Environment　and　John　Wiley　&　Sons　Ltd.
