Why Elecz?

Electricity prices change every hour. For AI agents, home automation, EV charging, and batch workloads — when you consume energy matters as much as how much you consume.

Elecz turns complex ENTSO-E market data into a single actionable signal:

"Run now. Electricity is cheap." "Wait until 03:00. Best 3-hour window starts then." "Switch to Tibber. Save 516 NOK/year."

Quickstart — Add to your agent

{
  "mcpServers": {
    "elecz": {
      "url": "https://elecz.com/mcp"
    }
  }
}

Your agent now understands spot prices, cheapest hours, energy state, and contract decisions — for Finland, Sweden, Norway, Denmark, and Germany.

Usage Examples

Example 1 — Contract recommendation

User prompt: "Should I switch my electricity contract? I'm in Finland and use about 3 000 kWh per year."

What happens:

  • Elecz fetches live contracts and ranks top 3 by annual cost for your consumption
  • Returns expected savings vs median market price
  • Provides direct links to switch

Example 2 — EV charging

User prompt: "When is the cheapest time to charge my electric car tonight in Sweden?"

What happens:

  • Elecz returns the best 3-hour consecutive window with average price
  • Includes start/end time ready for scheduling or Home Assistant automation

Example 3 — Business savings

User prompt: "What is the cheapest electricity contract for our office in Germany? We use 12 000 kWh per year."

What happens:

  • Elecz queries DE market with consumption=12000
  • Returns top 3 Arbeitspreis-ranked contracts with annual cost estimates
  • Prices are brutto ct/kWh including MwSt (19%)

Example 4 — Batch job timing

User prompt: "When is the cheapest time to run our nightly data processing jobs in Denmark?"

What happens:

  • Elecz returns cheapest hours for the next 24h
  • Returns optimal window to minimize energy cost for compute workloads
