Compare verified day-ahead wholesale electricity prices across European bidding zones. kWhPrice presents each market in its local time and keeps missing observations distinct from zero. Add electricity prices to your home screen with three widgets: current price, daily price curve and a lower-cost window. Check your selected market without opening the app, or tap a widget to see more. Widget updates depend on your device and data availability. Enable one optional daily notification when tomorrow’s prices are ready for your selected market. Choose quiet hours in the app. Use kWhPrice to: • check today’s and tomorrow’s published delivery intervals; • compare the daily average, lowest and highest interval; • browse verified yearly, monthly and daily archives; • explore recurring hourly patterns and plain-language historical analysis; • see negative prices too, with 15-minute, half-hourly or hourly intervals depending on the market; and • switch among 20 interface languages and 35 published bidding zones. The prices shown are wholesale market values, not a retail tariff or a final household bill. Supplier margins, network charges, taxes and fixed fees are not included. Market data comes from official sources, including the ENTSO-E Transparency Platform, OMIE and SEMOpx, depending on the bidding zone. Source publications can be delayed, incomplete or revised. kWhPrice requires no account and contains no advertising or cross-app tracking. We use existing server logs for aggregate usage statistics and service reliability. See the privacy notice for details about logging and optional notifications.
