How is this statistic computed?
Vantage Energies counts every hour from 2026-05-01 to 2026-05-31 in which the Norway NO2 (NO2) 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. From 1 October 2025, the count prices each hour at the mean of its four quarter-hour prices, or at the published hourly price for an hour without all four. The minimum is the lowest price on the hourly index, the figure the Vantage API reports. The hourly index is the zone's published hourly price, or the mean of the hour's four quarter-hour prices for an hour without one. A single quarter-hour can clear lower. A month with no such hour is a true zero, not missing data.
