This study aims to examine the factors that influence companies' intention to adopt battery energy storage systems (BESS), using the TOE framework (Technology, Organization, Environment). BESS are considered a key technology in the energy transition due to their potential to contribute to load balancing, increased grid stability, and cost reductions. Despite these advantages, it remains unclear which factors most significantly affect firms' decisions to invest in this technology. Therefore, this study investigates the role of TOE factors and how they interact in the decision-making process.A quantitative research design was employed, with data collected through a survey distributed to firms in four energy-intensive industries. A total of 116 complete responses were gathered. Regression analysis was used to test six hypotheses related to the following TOE factors: relative advantage, complexity, knowledge, firm size, government pressure, and competitive pressure. Five regression models were tested, each including different BESS applications (selling electricity, vehicle charging, heating, and backup power) as dummy variables.The results indicate that most TOE factors have a significant positive effect on adoption intention, and that application areas influence both the direct intention to adopt and the strength of the TOE factors. In particular, selling electricity and backup power were found to have a significant and strong positive effect on the intention to adopt BESS.Limitations of the study include its focus solely on commercial actors in four specific industries in Sweden, which limits the generalizability of the findings.The study offers both theoretical and practical implications. Theoretically, it demonstrates that the TOE framework is a useful tool for explaining technology adoption within the energy storage domain. Practically, it provides valuable insights for policymakers and technology providers regarding the key factors that influence BESS adoption among companies.Keywords: Battery Energy Storage Systems (BESS), Technology Adoption, TOE Framework, Regression Analysis, Energy Storage, Commercial Actors.
