Network codes are the legally binding rules governing how electricity flows across borders, connecting technical grid operation with market access across the EU.

Why this matters

[To be drafted]

Shared definitions

Europe's cross-border electricity networks are operated according to rules that govern the work of operators and determine how access to electricity is given to users across the EU. In the past, these grid operation and trading rules were drawn up nationally. As electricity is increasingly interconnected between countries, EU-wide rules effectively manage electricity flows in the internal energy market.

These rules, known as network codes or guidelines, are legally binding European Commission implementing regulations. They govern all cross-border electricity market transactions and system operations alongside the Regulation on conditions for accessing the network for cross-border electricity exchanges (EC) 714/2009.1)
