How is this statistic computed?
Vantage Energies counts every hour from 2026-05-01 to 2026-05-31 in which the Switzerland (CH) day-ahead price, from auction prices published on the ENTSO-E Transparency Platform (Nord Pool public data for the Nordic and Baltic zones), was below 0 EUR/MWh, on CET/CEST wall-clock days. An hour at exactly 0 EUR/MWh does not count. The zone's day-ahead prices are hourly, and the minimum is the lowest such price. A month with no such hour is a true zero, not missing data.
