Hourly electricity prices from elprisetjustnu.se for all four Swedish price regions — SE1 (Luleå), SE2 (Sundsvall), SE3 (Stockholm), SE4 (Malmö). Switch regions instantly. Prices update automatically; tomorrow's data appears the moment it publishes around 13:00.
The price you actually pay isn't just the spot price. Ström calculates the complete cost: spot rate plus 49.7 öre energy tax, then 25% VAT on top. Add your personal grid fee and the math updates immediately.
A bar and line chart spans the full day — all 24 hours at a glance. A second chart mode stacks each bar into its constituent parts: spot cost, energy tax, VAT, and grid fee, making it easy to see where the price actually comes from at any given hour.
Two home screen widgets: a small widget showing the current hour's price, and a medium widget with the current price alongside a spark line of today's curve. Both update via WidgetKit and read from a shared App Group cache — no redundant network calls from widget side.
Three additional WidgetKit targets: a large home screen widget showing the full day chart, a lock screen widget in both circular and inline variants, and an accessory widget that displays the cheapest upcoming window as plain text.
Background refresh fires at 13:05 daily — five minutes after Nord Pool releases tomorrow's prices. The app fetches, caches to App Group storage, and triggers a WidgetKit timeline reload so all widgets update without user interaction. A local notification fires on receipt of the new data.
