The purpose of this paper is to explore research clusters in Prosumption field through co-citation analysis. This study enriches our understanding by systematically reviewing Prosumption articles extracted from Web of Science (WoS) database at January 10, 2018, and consequently, we found only 350 publications. Co-citation analysis approach was applied for investigating research topics and identifying influential entities for the last 20 years with two bibliometric analysis tools, i.e., HistCite and VOSviewer. In total, we analyzed 350 articles and found three research clusters in prosumption; (1) Business and Sociology (2) Energy and Power grid and (3) Energy and Economy. But before exploring research clusters, we used HistCite to determine most influential authors, articles, journals, institutions, and countries in Prosumption field. Results indicated that prosumption is new and emerging field as academia focused their attention just a decade before. This bibliometric analysis reveals important gaps in the existing knowledge on prosumption and identifies relevant areas for future research.
