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 + Surcharges

Enter 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.
