Worked example with the prefilled values

This example shows how Peak Demand Grid Tariff Tool uses its starting values. Change the calculator inputs to estimate your own situation.

Peak demand
8 kW
Monthly rate per kW
70 NOK/kW
Monthly energy use
1000 kWh
Energy charge
0.4 NOK/kWh

Estimated monthly grid charge: 960 NOK

  • Annual amount11,520 NOK

Tariff model is simplified. Check your grid company's rates and peak-demand rules.

Formula and calculation logic

Estimated monthly grid charge = peak demand × monthly rate per kW + monthly electricity use × energy charge per kWh

Annual estimate = monthly estimate × 12

The estimate adds peak kilowatts × your monthly price per kilowatt to monthly energy use × your entered energy charge.

Assumptions

  • Grid companies define peak periods, peak averaging, and tariff bands differently. Enter the tariff from your own grid company; this is not a bill forecast.

Questions about this tool

How do I choose the peak tariff rate?

Use the monthly rate and peak-demand method published by your grid company. Tariff bands and the way monthly peaks are combined vary, so this estimate may not match a bill exactly.
