How a battery earns on Denmark’s day-ahead market

Denmark runs two price zones — DK1 (Jutland & Funen, linked to Germany) and DK2 (Zealand & Bornholm, linked to Sweden), both operated by Energinet. There is no subsidy for standalone storage — revenue is merchant: the daily price spread plus ancillary services (FCR) sold to Energinet. Over the last 30 days that spread averaged €155/MWh in DK1 and €152/MWh in DK2 — 142–145 % of the average price. That spread, not a subsidy, is what a Danish battery captures.
