European electricity bidding zones — EIC codes

A plain, machine-readable list of the EIC codes you need to query European electricity market data: 45 bidding zones, the 13 ENTSO-E document types worth knowing, and the 11 process types that go with them.

No dependencies, no API, no account. CSV and JSON, ~8 kB in total.

Why this exists

EIC codes are published by ENTSO-E as a set of spreadsheets that mix bidding zones, control areas, market participants and metering points into one file of several thousand rows. If all you want is "what do I put in in_Domain to get German day-ahead prices", that file is the wrong shape.

This repository is the subset that answers that question, kept in the form that a script can read.

The data

file	rows	what it is
data/bidding-zones.csv · .json	45	bidding zones, with the traps noted
data/document-types.csv · .json	13	documentType values (A44 day-ahead prices, A65 load, …)
data/process-types.csv · .json	11	processType values (A01 day-ahead, A18 intraday, …)

name,short,eic,note
Germany–Luxembourg,DE-LU,10Y1001A1001A82H,"One zone, four control areas"
Germany–Austria–Lux (historic),DE-AT-LU,10Y1001A1001A63L,Valid until 30 Sep 2018; needed for older series

Use it

import csv, urllib.request

url = ('https://raw.githubusercontent.com/whipeeer-creator/eic-codes/'
       'main/data/bidding-zones.csv')
rows = list(csv.DictReader(
    urllib.request.urlopen(url).read().decode().splitlines()))

zones = {r['short']: r['eic'] for r in rows}
print(zones['DE-LU'])      # 10Y1001A1001A82H

curl -s https://raw.githubusercontent.com/whipeeer-creator/eic-codes/main/data/bidding-zones.json \
  | jq -r '.[] | select(.short | startswith("IT")) | "\(.short)\t\(.eic)"'

Then, against the ENTSO-E Transparency Platform:

https://web-api.tp.entsoe.eu/api
  ?securityToken=YOUR_TOKEN
  &documentType=A44
  &in_Domain=10Y1001A1001A82H
  &out_Domain=10Y1001A1001A82H
  &periodStart=202601010000
  &periodEnd=202601020000

The traps, in one place

These are the ones that actually cost people time:

• DE-AT-LU vs DE-LU. Germany, Austria and Luxembourg were one bidding zone until 30 September 2018. Any series that crosses that date needs both codes — 10Y1001A1001A63L before, 10Y1001A1001A82H after. A query using only the modern code returns an empty document for the older period, not an error.
• Italy is six zones, not one. North, Centre-North, Centre-South, South, Sicily and Sardinia. Calabria was split off from South in 2021, so a long series changes shape mid-way. The islands decouple often, and the PUN is a consumption-weighted average — not a price anything is settled at.
• There is no single Nordic price. Norway has five zones, Sweden four, Denmark two (DK1 is synchronous with continental Europe, DK2 with the Nordic system). Averaging them into a "country price" hides spreads of several hundred percent.
• Ireland is one all-island market (SEM) covering the Republic and Northern Ireland, so it does not line up with either country's grid operator.
• Resolution is not constant. Great Britain settles in half-hours. Poland moved to 15 minutes with the 2024 reform, and the continental day-ahead auction moved to 15-minute products in 2025. Code that assumes 24 hourly points per day will silently mis-align.

Accuracy

Compiled by hand from the ENTSO-E Transparency Platform and checked against live API responses. If you find a code that no longer resolves, or a zone that is missing, open an issue — corrections are the point of publishing this.

Zone definitions change when markets split or merge. This is a snapshot, not a feed.
