This study is based on empirical knowledge created from simulations and investigating the technical aspects of how long a STATCOM can operate at full power in fault scenarios in the grid. A case study at Hitachi Energy is then conducted aiming to understand the possibilities that this technological answer could provide for a big industrial company and how it could beleveraged to increase its competitive advantage. Interviews and a life cycle analysis, focusingon emissions of power losses and installation costs are conducted. This is done to understand the biggest opportunities that the technical answers could give and if they can be commercialized to increase the sustainability of the STATCOM solution.The focus is put on the possibility of removing the Uninterrupted Power Supply (UPS) from the STATCOM solution and how this would affect the reliability and economy of the company selling the solution. Several advantages were identified and using a Thematic Analysis for the Interviews complemented with elements of Action Research, the advantages and motivations for removing the UPS from the solution were compared to the technical feasabilities to be able to conclude its possibility. The case study concludes that the STATCOM solution investigated at Hitachi Energy has the potential of removing the UPS from most of the projects and thereby offering a more sustainable and less complex solution to their customers. Further research on how to increase the time the STATCOM can operate without cooling is recommended by investigating the potential increase in temperature limitation in these fault scenarios.
