Congestion management measures comprise redispatching with operational and grid reserve power plants and countertrading. They can be cross-border or national measures and are needed to avoid or eliminate current-related or voltage-related congestion or meet requests from other countries.

The redispatching costs comprise the costs of financial compensation paid to operators of renewable energy installations, compensation paid to balance responsible parties under the BDEW (German Association of Energy and Water Industries) interim solution and the costs for redispatching with conventional power plants.
The grid reserve costs comprise the costs of contracting and deploying grid reserve plant capacity.
The countertrading costs are the difference between the costs of and the revenues from the transactions made.
