Tariff types

The tariff sets the prices used to value the self-consumption savings (what you stop buying) and the export income (what you sell). Off-grid installations have no tariff.

Step 3: tariff

Fixed

A purchase price and an export price that are constant all year. It is the simplest and the one used for most offers.

Parameter Example value
Purchase price (€/kWh) 0,21
Export price (€/kWh) 0,06
Contracted power (kW) 5,5

Indexed

The purchase price follows the wholesale market (pool) plus network tolls and charges. In Radiaris it is an approximation with editable average values:

Component Default
Average pool (€/kWh) 0,06
Network tolls (€/kWh) 0,07
Charges (€/kWh) 0,05

Approximation

The engine does not query real hourly prices from OMIE or ESIOS: it uses the values you enter. If you need another average price, edit the three components.

PVPC 2.0TD

Spanish regulated tariff with three periods:

Period Schedule Default price (€/kWh)
Off-peak From 0:00 to 8:00 every day, and all day at weekends 0,08
Peak Weekdays from 10:00 to 14:00 and from 18:00 to 22:00 0,25
Mid-peak The rest 0,15

All prices and the hours of each period are editable in «PVPC and indexed settings». The export is valued as a percentage of the mid-peak price (editable).

Contracted power and power term

The contracted power (kW) and the power term (by default €0.05/kW·day) determine the annual fixed cost of the tariff. It does not change the energy savings, but it appears as a fixed cost.

Which price to enter

  • Use the all-inclusive average price (energy + tolls + charges + taxes) from the client's bill for purchases.
  • For export, the compensation price paid by their electricity retailer.
  • Remember that VAT and the electricity tax are part of the effective price that is saved.
