Organizational growth remains a strategic priority for Kenya's energy sector as organizations strive to enhance operational efficiency, financial sustainability, service reliability, and long term competitiveness amidst rapid technological transformation, increasing energy demand, and evolving regulatory requirements. Despite sustained public and private investment in energy infrastructure, many organizations continue to experience delayed project implementation, budget overruns, inefficient utilization of financial and human resources, and inconsistent organizational growth. Evidence increasingly suggests that these challenges arise not from deficiencies in strategic planning but from ineffective resource allocation during strategy implementation. Although previous studies have acknowledged the importance of resource allocation in organizational performance, existing evidence remains fragmented, with most studies examining resource allocation alongside other strategic management practices rather than establishing its independent influence on organizational growth within Kenya's energy sector. This study examined the influence of resource allocation on organizational growth in Kenya's energy sector. The study was anchored on the Resource Based View Theory and adopted a cross sectional explanatory research design. Primary data were collected using structured questionnaires administered to managerial, technical, and operational employees drawn from selected public and private energy sector organizations in Kenya. Data were analyzed using descriptive statistics and multiple linear regression analysis. The findings established that resource allocation exerted a positive and statistically significant influence on organizational growth. Organizations characterized by timely, strategic, and adequate allocation of financial, human, and technological resources reported superior growth in operational efficiency, service reliability, organizational capability, and overall institutional performance. The findings affirm that effective resource allocation constitutes a critical strategy implementation practice through which organizations translate strategic intent into sustainable growth outcomes. The study contributes to strategic management literature by providing context specific empirical evidence on the role of resource allocation in promoting organizational growth within Kenya's energy sector. The findings further provide practical insights for managers and policy makers seeking to strengthen strategy implementation through improved resource planning, prioritization, and deployment to enhance sustainable organizational growth.
