Charging an EV in Kosovo this week: what the prices actually said
All numbers computed from the week's published auction results at publication and frozen — this article is an honest snapshot, not a page that rewrites itself. Reproduce via the API.
The gap between daytime and evening prices was the defining feature this week. Across the six days, the cheapest charging window averaged 46,07 EUR/MWh, while the evening peak averaged 163,69 EUR/MWh — a difference of 72 percent. That spread is not a rounding detail; it is the whole case for timing your charging.
The daytime windows opened mostly in the late morning, between 07:00 and 11:00, and their cost varied widely: 15 EUR/MWh on 12 July against 84,84 EUR/MWh on 17 July. Evenings were consistently expensive, topping out at 235,09 EUR/MWh on 17 July. In practice, the same charge that was affordable at midday became markedly costlier once the evening peak set in, and that pattern held on every day in the set.
For a driver charging 150 kWh a week, shifting load into the cheaper window rather than the evening peak was worth 17,64 EUR over the week, or 917 EUR across a year. The concrete takeaway: plug in during the late-morning window and avoid the evening entirely — the price data rewarded that habit every single day this week.
Every day at 13:00 CET, an auction sets electricity prices for every hour of tomorrow — separately, for each European bidding zone. Those prices routinely differ by a factor of two to three within a single day, because solar floods the middle of the day and demand peaks in the evening. If you charge an EV, that spread is money: the car doesn't care when it charges, only that it's full by morning. This is what the spread looked like in XK this week.

Local time. Notice the window MOVES — sometimes after midnight, sometimes midday when solar peaks. A fixed night tariff catches some of this; following the auction catches all of it.
Automate it in ten minutes
You don't need to read auction results at 13:00 every day — ask the API for the cheapest window and let your wallbox follow it. One call:

https://voltcast.com/api/v1/optimize/cheapest-windowHome Assistant users: the Voltcast integration exposes the same window as a sensor you can automate against; evcc users get a ready-made tariff config. The Home plan (€9/mo) covers one zone of your choice with 7-day forecasts — the free tier lets you test everything on DE-LU first. And if you want to charge on a forecast of tomorrow before the auction even publishes, that's the P50 curve — scored publicly every day so you know exactly how much to trust it.
