Commission Guideline on Capacity Allocation and Congestion Management (CACM)
The CACM (Capacity allocation and congestion management) Regulation, the first of the ten EUs electricity network codes and guidelines developed in accordance with the EU Third Energy Package, is expected to come in force in July/August 2015.
The CACM Regulation sets out the pan-European rules for day ahead and intraday cross-border trading (market coupling). To achieve this, the CACM Regulation establishes new entities such as NEMOs to operate single day ahead and intraday coupling, and specifies the approach to defining bidding zones, calculating cross-border capacities and managing congestion. It also requires TSOs and NEMOs respectively to develop and propose common methodologies, terms and conditions for approval by National Regulatory Authorities (NRAs) within fixed legal timelines.
