Electricity Tariff
Settings → Electricity Tariff tells the Portal what you pay for electricity and what you earn for exporting it. Your profit statistics — and any price-based work mode — depend on it.

Choose your tariff type
| Tariff type | Use it when |
|---|---|
| Fixed Rate Setup | You pay one constant price per kWh |
| TOU Rate Setup | Your price depends on the time of day (time-of-use tariff) — define the periods and their prices |
| Trading Price | You are on a dynamic tariff that follows the wholesale market hour by hour |
Trading Price (dynamic tariffs)
With Trading Price selected:
- Price Information Source — the market feed used for prices (e.g. ENTSO-E Day-Ahead for European markets)
- Buy Price (Import) and Sell Price (Export) are derived from the market price with your supplier's mark-up:
Buy Price = Market Price × Coefficient + Surcharges
Sell Price = Market Price × Coefficient + SurchargesEnter the coefficient and surcharges from your supplier's contract so the calculated prices match your bill. The chart below the settings shows the resulting hourly buy/sell prices for the selected day.
💡 The currency shown (e.g. Euro €) follows your home's country.
💡 After correcting a tariff that was wrong for a while, run a [Profit Calibration](Savings and Profit.md) so your historical profit figures are recalculated with the right prices.
