Exchange of real-time information between TSO and DSO is a common practice, however usually with existing potential for improvement. The necessary enhancements may include increasing the detail of data exchange concerning already observable parts of transmission and distribution networks, but also expanding the set of TSO-DSO data exchange to non-observable parts of each other networks.<br/><br/>Aiming to enable a better supervision and control of transmission and distribution networks, this use-case focuses on guaranteeing that the necessary real-time information exchange between TSO and DSO is put in place. Standardization/normalization of real-time data exchange between TSO and DSO will be addressed for better understanding of counterparty signals.<br/><br/>The use-case will as well establish the needed procedures to allow periodic updates of the observability area of both TSO and DSO. This will ensure adequate visibility on each other networks regardless of any network topological changes over time.<br/>
