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 measured completeness against a DST-aware expected count. 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.
