Network codes are part of the package of tools of European energy policy.
Network codes are associated with the aim of the EU's third energy package that entered into force in July 2009 concerning the European internal market in electricity.
Electricity market legislation included in the third package is
- Directive concerning Common Rules for the Internal Market in Electricity (2009/72/EC)
- Regulation concerning Establishing an Agency for the Cooperation of Energy Regulators (713/2009)
- REGULATION (EC) No 714/2009 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL.
The network codes are legislation subject to Regulation 714/2009.
From a point of view of their legislative status, the network codes are European regulations, i.e. they arelegislation directly in force in EU member states. As European legislation, the network codes are ahead of national legislation in the hierarchy, and in case of conflict, override it. The member states are responsible for implementing the network codes.
The network codes are divided into three groups: connections, operations and the market codes.
