This study examined electricity generation management as a correlate of academic staff productivity in Lagos State public Universities, Nigeria. The erratic electricity supply in the universities remains a critical challenge to academic staff productivity. The study anchored on System Theory. Three research questions were raised, and three null hypotheses were tested at a 0.05 level of significance. The study adopted a correlational design and the targeted population of the study comprised 3,126 academic staff in public universities in Lagos State including Lagos State University (LASU), Lagos State University of Education (LASUED), Lagos State University of Science and Technology (LASUSTECH); and University of Lagos (UNILAG). A Taro Yamane sample of size of 355 academic staff were selected through simple random sampling techniques. Two research instruments titled ‘Electricity Generation Management Questionnaire’ (EGMQ) and ‘Academic Staff Productivity Questionnaire’ (ASPQ) were used for data collection. Content validity of the instruments was ensured by test experts and reliability consistency of the instruments was at 0.72 and 0.73 using Cronbach’s alpha. The Kendall’s tau-b correlation was used to analyse data collected via Statistical Package for Social Science (SPSS) version 26.0.  The findings of the hypotheses 1, 2 and 3 showed that: a significant relationship existed between organising power plant operation and academic staff productivity in public universities in Lagos State, Nigeria (τb = .541; N=355; p<0.05); a significant relationship existed between renewable energy integration and academic staff productivity in public universities in Lagos State, Nigeria (τb = .577; N=355; p<0.05); and a significant relationship existed between electricity generation management and academic staff productivity in public universities in Lagos State, Nigeria (τb = .602; N=355; p<0.05). The study concluded that integration of renewable energy and organising power plant operation into university system enhances academic staff productivity. Therefore, it is recommended amongst other that university management should provide adequate funding to generate stable electricity supply toward improving academic staff productivity in Lagos State public universities.
