ENTSO-ECapacity Allocation & Congestion Management
The Guideline on Capacity Allocation and Congestion Management sets out the methods for calculating how much space can market participants use on cross border lines without endangering system security. It also harmonises how cross border markets operate in Europe to increase competitiveness but renewables’ integration. CACM is the cornerstone of a European single market for electricity.

History & Development of the network code
Below you will find the Frequently asked questions relating to the network code Capacity Alloc. & Congestion Management.
CACM sets out the methods for allocating capacity in day-ahead and intra-day timescales and outlines the way in which capacity will be calculated across the different zones. Putting in place harmonised cross border markets in all timeframes will lead to a more efficient European market and will benefit customers. These rules will provide the basis for the implementation of a single energy market across Europe.
CACM was the second network code to be developed by ENTSO-E and represents an important step in implementing a ‘Target Model’ for the design of European electricity markets. It has been developed through an open and transparent process involving stakeholders at every stage and therefore reflects a broad range of views.
CACM entered into force in August 2015. The entry into force of the CACM guideline marks the start of the formal implementation period, during which Europeans including Member States, ENTSO-E, TSOs, regulators, power exchanges, market participants will collaborate to develop the methodologies and tools described in CACM. Go to the dedicated section for more information on implementation projects and how stakeholders can be involved.

Background
The network codes and related guidelines have been developed to help realise Europe’s three energy policy goals – of ensuring security of supply; creating a competitive Internal Electricity Market; and decarbonising the electricity sector. For this to happen, the network codes and related guidelines will be implemented and complied with across Europe.
Each code requires a series of steps to be taken before they can enter into force. This could be national decisions, the conclusion of regional agreements or the creation of more detailed methodologies. All market participants, DSOs, TSOs and regulators will be involved and there will be extensive development work and consultation required.
CACM sets out rules for calculating cross-border capacity, defining and reviewing bidding zones and operating day ahead and intraday markets. Many of the subjects included in the CACM are highly complex and there is relatively little operational experience on which to draw from (for example the flow-based method of capacity calculation). For this reason, CACM requires additional work and a series of methodologies to be jointly developed and approved by regulators after the code enters into force.
