This proposed paper focuses on the criteria that need to be met to allow network operators to effectively use Dynamic Line Ratings in real-life operations. Today DLR has reached a point where the focus of research & testing has moved on from how to determine the most reliable & accurate rating to how to effectively integrate DLR in the processes of the network operators and maximize the use of the network. Different pilot projects in Europe and around the world have proven the DLR technology works in the field and many papers within CIGRE and other organizations highlight those results, but now the focus is shifting to how this technology can be put to best use: where it makes sense and how the results should be used to maximize the benefits while reducing the operational risks. The paper will highlight the experience the Belgian TSO, Elia, has had regarding those questions. The specific aspects detailed here is the usability of day-ahead forecasting of DLR. Indeed, most decisions regarding network operation and Electricity Market are taken many hours/days in advance; therefore if DLR is to influence these decisions, a reliable forecast of the dynamic rating values is required. This is very similar to the need for the forecast of wind & sun production that allows the safe integration of those intermittent energy sources into the powe
