To meet the targets of a fully decarbonised and sustainable electricity system by 2050, the adaption and extension of the existing transmission system is crucial. This evolution of the grid has started, with approximately 80 % of grid development projects identified in the Ten-Year Network Development Plan (TYNDP) 2018 being related to the integration of renewable energy sources (RES).

Meanwhile, a significant share of projects encounters delays in implementation. These delays have two direct consequences for the EU achieving its carbon reduction targets: the missing grid capacity hinders the further growth and integration of RES, while the resulting grid congestion must be resolved by expensive and CO2 intensive redispatch measures.
