  • compare_marketsCompares the current electricity price across every covered European market, sorted cheapest first by all-in price.No findings

    Why it is in this group

    • The name "compare_markets" says "compare": a word for reading.
    Description, as the server wrote it
    Compares the current electricity price across every covered European market, sorted cheapest first by all-in price. All figures are EUR per kWh so markets are directly comparable. The snapshot is refreshed at most hourly (see asOfUtc) and uses the current hour's average price. All-in = variable household price per kWh: spot + energy tax + per-kWh grid fee + VAT. Fixed monthly charges (grid capacity, tax credits) are excluded. Spot = wholesale day-ahead price.

    • The name "get_current_price" says "get": a word for reading.
    Description, as the server wrote it
    Gets the electricity price for the current delivery period (15- or 60-minute slot) in one market: the all-in household price and the wholesale spot price, per kWh, in the market's own currency and in EUR. All-in = variable household price per kWh: spot + energy tax + per-kWh grid fee + VAT. Fixed monthly charges (grid capacity, tax credits) are excluded. Spot = wholesale day-ahead price.

    Why it is in this group

    • The name "get_prices" says "get": a word for reading.
    Description, as the server wrote it
    Gets one day's electricity prices for a market as hourly averages (normally 24 rows; 23 or 25 on daylight-saving change days), with the day's min, max and average and the cheapest/most expensive hour. Days are day-ahead delivery days in Central European time (Europe/Amsterdam, CET/CEST); hour starts are given in that local time. Prices are per kWh in the market's own currency. Tomorrow's prices are published around 13:00 CET each day; before that, asking for "tomorrow" returns a not-yet-published message. All-in = variable household price per kWh: spot + energy tax + per-kWh grid fee + VAT. Fixed monthly charges (grid capacity, tax credits) are excluded. Spot = wholesale day-ahead price.

    Why it is in this group

    • The name "list_markets" says "list": a word for reading.
    Description, as the server wrote it
    Lists every European electricity market (bidding zone) SpotWave covers, with its code, display name and billing currency. Use the code (e.g. "NL", "DE", "SE3", "NO1", "DK1", "ITN") as the `market` argument of the other tools. Countries split into several zones (Sweden, Norway, Denmark, Italy) have one code per zone.
