1. Prices rose 17% - driven by winter volatility

Eastern Denmark’s average wholesale price climbed from €71 to €83/MWh. Like most of Europe, the increase concentrated in Q1 2025, when cold weather and calm conditions hit the wind-dependent Danish grid hard.

Q1 2025 was 38% more expensive than Q1 2024. But from spring onwards, abundant wind and solar generation brought prices back to more normal levels. Summer and autumn were relatively stable.

The takeaway: If you’re on a dynamic tariff, your winter bills were higher than last year. But smart timing could still keep costs manageable.

2. Weekend savings of 65% - among the best in Europe

Denmark’s weekend price dip is exceptional. Charging at midday on weekends instead of the evening peak saves you 65%.

Weeknight savings are still solid at 44%, but the real opportunity is weekend daytime - when wind generation often exceeds demand and prices plummet.

This is the opposite pattern from Finland, where overnight beats daytime. In Denmark, weekend midday is your best window.

Gridio captures these weekend dips automatically, shifting charging to catch the lowest prices whether they occur overnight or during the day.

The takeaway: Denmark rewards flexible weekend charging more than almost any other market. If you can charge Saturday or Sunday afternoon, do it.

3. 265 hours of negative prices

In 2025, wholesale prices went negative for 265 hours - down slightly from 2024 (-4%). Denmark’s wind-heavy grid regularly produces more electricity than needed, especially on breezy weekends.

Most negative hours occur when strong winds coincide with low demand - typically weekend afternoons and nights. If you’re on a dynamic tariff, these are free charging opportunities.

The takeaway: Dynamic tariffs unlock access to free electricity. 265 hours means roughly one day per month where charging costs nothing - or earns you money.

4. Monday and Sunday are your best days

Not all days are equal. Wholesale prices follow non-domestic energy use - offices, factories, commercial buildings - and that demand varies through the week.

Monday is the cheapest weekday in eastern Denmark, before the week’s activity fully ramps up. Wednesday and Thursday tend to be the most expensive.

Sunday is the cheapest weekend day, when both commercial demand and household activity are at their lowest. Saturday is good too, but Sunday edges it out.

The takeaway: Sunday is your ultimate charging day in Denmark. If you can wait until Sunday afternoon, you’ll get the best rates of the week.

5. The best times to charge your EV

Let’s make it practical. Based on 2025 data, here’s when to charge:

Weekdays (plugged in overnight):

Prices are lowest around 03:00 at €69/MWh. The evening peak (19:00-21:00) averages over €120/MWh, so avoiding it saves you 44%.

Weekends (flexible all day):

Charge at 13:00 for the best rates - around €36/MWh. This is where Denmark shines: weekend midday prices are less than a third of weekday peak prices.

If it’s windy, prices may even go negative. Check your dynamic tariff app for real-time opportunities.

The hour to avoid at all costs: 19:00-21:00 on weekdays. Peak demand, peak price - nearly double the overnight rate and more than triple the weekend midday rate.

The takeaway: Denmark’s pattern is clear: weekend midday beats overnight. Target Sunday 13:00 for the absolute cheapest charging.

The bottom line

2025 saw Danish prices rise moderately, driven by a difficult winter. But the weekend opportunity remains exceptional - 65% savings are available for drivers who can shift charging to midday on Saturdays and Sundays.

The gap between smart and dumb charging is among the widest in Europe. If you’re still plugging in at 19:00 or ignoring weekend opportunities, you’re paying far more than necessary.

A dynamic tariff plus smart timing is the simplest upgrade you can make.

Charge smart. Charge cheap.
