Most people reach for ENTSO-E and stop there. EEX Transparency carries much of the same fundamental data, sometimes earlier, and covers producers who report through it under REMIT. If you care about outages, this is not optional.
EEX is the European Energy Exchange, based in Leipzig. The transparency platform is a regulatory obligation under REMIT, not a commercial product — which is why the data is free and the interface is what it is.
European market participants are legally required under REMIT to publish inside information — chiefly outages of generation and consumption units — before trading on it. They must do so through an approved platform, and EEX Transparency is one of the main ones.
That legal obligation is what makes the platform useful: it is not a convenience publication that a TSO consolidates overnight. It is a disclosure that a trader is required to make as soon as the information exists, because trading on it beforehand is market abuse.
| Dataset | Notes |
|---|---|
| Transparency messages (outages) | Planned and unplanned unavailability of generation, consumption and transmission units, with capacity affected, reason and expected end. |
| Actual generation | Per unit and per fuel type, for units whose operators report here. |
| Installed capacity | Per unit, the denominator for availability calculations. |
| Cross-border flows and capacity | Where operators publish through EEX rather than a TSO platform. |
Coverage varies by country and by company. Some producers publish through EEX, others through national platforms, others through their own websites. No single source has all European outages, which is the uncomfortable fact behind every fundamental model.
The public site at transparency.eex.com offers filtered views and file downloads, which is enough for research. For automated use, EEX offers data interfaces under its Datasource product; the free public route is the site itself and its exports.
| EEX Transparency | ENTSO-E | |
|---|---|---|
| Why it exists | REMIT disclosure obligation | Regulatory transparency publication |
| Timing | When the operator knows | On a publication schedule |
| Coverage | Operators who report through EEX | All zones, via TSOs |
| Shape | Message-oriented, versioned | Time series, one schema |
| Best for | Outages, unit-level events | Comparable series across every zone |
They are complements, not alternatives. A serious fundamental stack reads both, keys them together by unit where it can, and keeps the publication timestamps from each — because the difference between them is itself a signal about how fast the market learned.
We build outage and fundamentals pipelines that keep every version and every publication time, so backtests reflect what was actually knowable. If that is the problem you have, talk to us.
