In the last years, the progressively growing renewables’ production capacity has increased fluctuating infeed. And, as the lines’ transmission capacities have not been upgraded simultaneously, this has resulted in the increase of congestions number in the electricity transmission grids across Europe. Thereby, countries like Germany have lately seen an enormous increase in their redispatch cost. Therefore, the need for an improved congestion management has day by day become more impelling within the continent. In order to cope in an adequate way with the increase of congestions in the short and medium term, before the still necessary power networks upgrade. As a result, having recognized inside the establishment of optimal zonal pricing mechanisms the answer to this necessity, the European Union has emanated in 2011 through the Agency for the Cooperation of Energy Regulators the Framework Guidelines on Capacity Allocation and Congestion Management for Electricity, which actually has tried to clarify the rules for creating optimal zonal configurations.
