Increase in Efficiency and Acceptance of the Energy Transition through Redispatch Reservation

In some regions of E.DIS’s high-voltage grid, up to 15% of the renewable energy (EE) generation is already curtailed. The reason is that the expansion of renewable energy sources is happening much faster than the grid can be upgraded. Existing grid capacities are inadequately considered during the expansion of renewable energy sources. The goal must be to integrate as much renewable energy into the grid as possible, despite the lagging grid expansion. There is a need for incentives to synchronize the timing and spatial aspects of renewable energy expansion with the existing grid capacities.

The Redispatch Reservation proposes a “bridge” until the grid expansion is completed and provides incentives for locations with “free access” to inject renewable energy. This way, despite significant grid bottlenecks in the generation regions, more renewable energy can be utilized, and unnecessary costs for end customers can be avoided.

In a joint publication by E-Bridge and E.DIS, a simple, transparent, and non-discriminatory process is presented, which could ensure a smooth implementation of the Redispatch Reservation. Considering the future of energy supply in Germany, synchronization between renewable energy development and grid capacities is of crucial importance.
