EAN Code

An EAN code (or EAN number) is the unique identification code of a connection to the electricity grid. EAN stands for European Article Number, but in the energy sector it refers to an 18-digit code that uniquely identifies each grid connection. In the Netherlands, these codes typically start with 871, followed by 15 digits.

  • A large industrial connection, such as a factory, has its own EAN code
  • Connections within a closed distribution system (GDS) or MLOEA also have their own EAN code

Why is the EAN code important for GOPACS?

In GOPACS, the EAN code is used to:

  • determine on which grid level (location) a connection is situated
  • link the connection to a CSP that offers flexible capacity on its behalf
  • check whether the offered flexible capacity is technically usable for a congestion issue
  • validate and verify the activated capacity (e.g. using measurement data)

The EAN code is therefore an operational anchor in the system — it clarifies where flexibility comes from, who is responsible, and how it can be measured.

From grid operators, for the market

GOPACS is the joint initiative of all Dutch grid operators. We coordinate solutions to grid congestion, provide transparent insights into the congestion market, and encourage the flexible use of electricity to keep the energy system resilient and future-proof.
