Operator generation-per-unit data, national plant registers and Vindmark's weather-driven output model
Unit-level actuals where published; modelled from weather reanalysis and asset specifications elsewhere, flagged per record
Asset-level renewable generation for traders, asset owners and investors who need to know what each plant actually produced, not just the zone total.
Actual output comes from unit-level generation data where operators publish it, which covers most assets above 100 MW. For smaller assets Vindmark models output from weather reanalysis, turbine or module specifications and observed zone totals; every record carries a source_type flag so you can separate measured from modelled values. Forecasts are produced by Vindmark's own weather-driven model and are delivered with the forecast issue time, so they can be backtested without look-ahead bias. Coverage starts in 2017 for the Nordics and Germany and in 2019 for the remaining zones.

Every Scope 3 figure is labelled as reported or modelled with the model version, which our auditors insisted on. Coverage of smaller listed companies is mostly modelled, and they are upfront about it.

Day-ahead and intraday prices for all Nordic and Baltic zones arrive within minutes of publication, and the cross-border flow data is aligned to the same intervals. Good value compared with what we paid before.
