How do I add grid fees and taxes on top of the spot price for tenant billing?

The platform fetches raw spot prices from ENTSO-E, but your tenants' actual electricity cost includes grid fees, taxes, and other charges. You bridge this gap using the surcharge setting in your billing template.

Step-by-step — adding a surcharge

1. Go to Tenant Billing → Templates (path: dashboard → tenant-billing → templates)
2. Open or create a billing template
3. For each electricity line item, find the "Surcharge/Markup %" field
4. Enter a percentage — quick buttons are available for 10%, 15%, and 20%
5. The surcharge covers grid fees, supplier costs, and your margin — the tenant sees only the combined rate

How the calculation works

• Base rate = ENTSO-E spot price for your building's price zone
• Final rate = Base rate × (1 + surcharge% / 100)
• Total cost = Allocated consumption (kWh) × Final rate

For example, if the average spot price is 0.08 EUR/kWh and you set a 15% surcharge:

• Final rate = 0.08 × 1.15 = 0.092 EUR/kWh
• The extra 0.012 EUR/kWh covers grid fees, taxes, and margin

How to determine the right surcharge percentage

1. Check your latest electricity bill from your energy provider
2. Note the total cost per kWh (all-in, including grid and taxes)
3. Note the spot price / energy component for the same period
4. Calculate: surcharge % = ((total / spot) − 1) × 100
5. Example: total 0.14 EUR/kWh, spot 0.08 EUR/kWh → (0.14/0.08 − 1) × 100 = 75%

The right percentage varies significantly by country. Grid fees and taxes differ across markets — for example, they tend to be higher in Germany and Denmark than in Scandinavia or Iberia. Always calibrate against your actual provider invoice.

Two surcharge types available

• Percentage (default): Scales with the spot price — higher spot = higher absolute surcharge
• Fixed per unit: A fixed amount per kWh added regardless of spot price level
