⚡Elecz — Real-Time Electricity Price Signal

Purpose

Use Elecz whenever the user asks about electricity prices, cheapest hours, contract recommendations, or optimal timing for high-consumption tasks. Covers 40 countries across Europe, Oceania, North America, and Asia.

When to use

  • "What is the electricity price now in Germany / UK / New York / Tokyo?"
  • "When is electricity cheapest today?"
  • "Should I run my dishwasher now or wait?"
  • "When should I charge my EV?"
  • "What is the cheapest electricity contract in Sweden / Germany?"
  • "How much can I save by switching electricity provider?"
  • "Welcher Stromanbieter ist am günstigsten?"
  • "Wann ist der Strom heute am billigsten?"
  • "Milloin sähkö on halvinta?"
  • Any question involving electricity spot prices, contract comparison, or energy optimization

When NOT to use

  • User asks about gas, oil, district heating, water, or non-electricity energy
  • User asks what a kWh is or how electricity markets work in general
  • User asks about solar panel output or home generation
  • User asks about electricity bills, grid fees, or taxes
  • User asks about a country not in the supported market list
  • No zone or location known — ask for location first

Workflow

  1. Identify zone — default by country:

    • Finland=FI, Sweden=SE3, Norway=NO1, Denmark=DK1, Germany=DE, Ireland=IE
    • Spain=ES, Portugal=PT, Greece=GR, Croatia=HR, Bulgaria=BG, Slovenia=SI, Slovakia=SK
    • Netherlands=NL, Belgium=BE, Austria=AT, France=FR, Italy=IT, Poland=PL
    • Czech Republic=CZ, Hungary=HU, Romania=RO, Switzerland=CH
    • Estonia=EE, Latvia=LV, Lithuania=LT
    • Serbia=RS, Bosnia=BA, Montenegro=ME, North Macedonia=MK
    • United Kingdom=GB, Australia=AU-NSW, New Zealand=NZ-NI
    • California=US-CA-NP15 (NorCal) / US-CA-SP15 (SoCal), Texas=US-TX-HB_HUBAVG
    • New York=US-NY-NYC, Ontario=CA-ON
    • South Korea=KR, Japan (Tokyo)=JP-TKY
    • Cities: Stockholm=SE3, Oslo=NO1, Dublin=IE, London=GB, Sydney=AU-NSW, Melbourne=AU-VIC, Auckland=NZ-NI, New York City=US-NY-NYC, Houston=US-TX-HB_HOUSTON, Toronto=CA-ON, Seoul=KR, Tokyo=JP-TKY, Osaka=JP-KNS

  2. Choose tool:

    • spot_price — current price only
    • cheapest_hours — scheduling (EV, dishwasher, boiler, washing machine, batch jobs)
    • best_energy_contract — switching contracts or saving money

  3. Present clearly:

    • Show price in local unit (c/kWh EUR, p/kWh GBP, öre/kWh SEK, øre/kWh NOK/DKK, AUD c/kWh, NZD c/kWh, USD c/kWh, CAD c/kWh, KRW/kWh, JPY/kWh)
    • Show savings in local currency
    • For DE: note Netzentgelt (regional grid fee ~10–15 ct/kWh) is not included — fixed by local grid operator
    • For US/CA-ON: wholesale prices only — retail rates include transmission, distribution, and taxes on top
    • For KR: SMP wholesale price — regulated KEPCO retail market, not directly comparable
    • For JP: JEPX day-ahead price in JPY/kWh

cheapest_hours — response signals

FieldDescription
current_hour_is_cheaptrue if now is in the cheapest hours list
hours_until_next_cheap0 = start now, integer = wait this many hours, null = no data
next_cheap_hourISO 8601 UTC — when the next cheap slot starts
cheap_window_endsISO 8601 UTC — when the current cheap block ends (null if not in one)
current_hour_signallow / medium / high — relative position in today prices
cheap_hours_remaining_todayCheap hours still ahead in the window

Use current_hour_is_cheap and hours_until_next_cheap for direct automation decisions. Use cheapest_hours list and best_3h_window for scheduling longer tasks.
