In the analysis “Security of Supply in North Rhine-Westphalia in 2030”, the EWI examines the security of supply in Germany and North Rhine-Westphalia on a model basis, both on the market side and on the grid side. In connection with the planned early coal phase-out, it is determined that the annonced capacities of 3GW of hydrogen-capable gas-fired power plants in the analysed scenarios are insufficient ed capacities of 3GW of hydrogen-capable gas-fired power plants in the analysed scenarios are not sufficient to cover the assumed gross electricity demand. The realisation of 25 GW of hydrogen-capable gas power plants could ensure security of supply, provided there is significant grid expansion. However, delays in system-relevant line projects could cause local supply gaps as well as an increase in adaptation measures to eliminate grid bottlenecks. The EWI is developing a monitoring system for the NRW Chamber of Industry and Commerce in order to track the development of system-relevant parameters in NRW over time and to identify challenges for the security of supply in the energy system at an early stage.
