'UIOSI' (use-it-or-sell-it) principle means the rule according to which the underlying cross zonal capacity of physical transmission rights purchased and non-nominated is automatically made available for day-ahead capacity allocation and according to which the holder of these physical transmission rights receives remuneration from the Transmission System Operators (TSOs) (Article 2(6) of the Network Code on Forward Capacity Allocation).
According to Article 38(7) of the Commission Regulation (EU) 2017/2195 of 23 November 2017 establishing a guideline on electricity balancing if physical transmission right holders use cross zonal capacity for the exchange of balancing capacity, the capacity shall be considered as nominated solely for the purpose of excluding it from the application of the use-it-or-sell-it (‘UIOSI’) principle.
