Voltstack pulls official European market data and shows you exactly how healthy each feed is. No other vendor shows you this page.

Every row below is generated from the same envelope the app itself reads: live or fallback, cache age, and, for the series that measure it, completeness against a DST-aware expected count weighted by the market time unit actually in force. A dash means the series publishes no completeness figure, or that the count and the resolution disagreed and we refused to print a number we cannot stand behind. Nothing here is written by hand.

Cross-validation

A nightly job re-derives yesterday's settled day-ahead prices from independent publications of the same fundamentals and compares them against what our own pipeline stored. Green means the numbers in our database match the reference within tolerance (mean |Δ| ≤ €0.05/MWh); a miss pages us before you would notice it.

Pending integrations

Sources we have deliberately not shipped yet, and why. Where an upstream operator's terms are unclear we ask them directly instead of pulling data first, so each row below unlocks with the named event. This list is published for the same reason the feed table above is: you should not have to guess what is behind the numbers.

SourceCoverageStatusDetail
Gassco nominations (umm.gassco.no)Aggregated Norwegian pipeline nominations, nine points, five-minute updatesscope not confirmedGassco confirmed on 11 Sep 2026 that UMM data is free for automated use. The system events that confirmation covers are live above. The nominations pages are a separate question: they sit behind the site’s click-through disclaimer, and the reply answered about UMM without naming the flow data, so we asked Gassco to confirm that half in writing rather than reading the answer more widely than it was given. Nothing here polls those pages in the meantime.
EEX EUA auction calendarForward EUA auction dates and volumesnot loadedThe auction RESULTS are live: EEX granted written approval on 29 Jul 2026, for primary auctions only — spot prices and futures are excluded and would need a separate licence. The forward calendar is a different problem. EEX publishes it as a spreadsheet whose volume rows are packed positionally rather than aligned to their dates, so in any week where a weekday has no auction the volumes shift left and land against the wrong day. Checked against the results file for 2026, that misdates roughly one scheduled day in seven. We would rather show no forward schedule than a plausible wrong one.
