D7.7 Cost-benefit analysis

This report details the final exploitation activity and provides an economic assessment of the application of MiniStor in five different use case scenarios. The analysis follows the technical results and simulations carried out in D6.7, taking into consideration some of the main use cases. It presents costs for prototyping and market competitor prices, detailing the services that MiniStor can provide at the level of residential buildings. The economic simulations for the five use cases take into account the reverse approach for calculating the simple payback time. This reverse approach is employed because it is not possible to have a defined market price for the MiniStor solution at TRL 7. This approach identifies the economic benefits of the MiniStor scenario in relation to the baseline, considering literature data on end-of-life technologies and the PBT commonly accepted by the residential building customer segment. A range of possible market prices accepted by customers is analysed. The final assessment provides interesting data on the preliminary reduction in costs of the MiniStor subcomponents, which are presented in the final comments.
