The All-Island Ten Year Transmission Forecast Statement (TYTFS) describes and presents technical network data such as the network configuration, network parameters, generation connections and power flows, and fault levels for future network conditions. This enables the reader to carry out their own network analysis if they wish. In addition, the TYTFS outlines opportunities for demand and generation connections in Ireland and Northern Ireland. The TYTFS forms part of SONI’s and EirGrid’s statutory and licence obligations.
