Peak/Off-Peak Electricity Calculator

Electricity prices in Denmark vary throughout the day based on supply and demand. During peak hours (typically 6:00โ€“21:00 on weekdays), prices are significantly higher than during off-peak hours (nights and weekends). This calculator shows how your current consumption split between peak and off-peak affects your total cost.

How Time-of-Use Pricing Works

With hourly electricity pricing becoming standard in Denmark through smart meters, consumers can benefit from using electricity when it is cheapest. The grid tariff from your local network company is also time-differentiated, with higher rates during peak demand. The price difference between peak and off-peak can be 1.00โ€“2.00 kr per kWh or more.

Strategies for Shifting Consumption

Smart plugs, timers, and home automation systems can help you automatically shift consumption to cheaper hours. Programming your dishwasher and washing machine to run at night, charging your electric car between 00:00 and 06:00, and using a timer on your hot water tank are practical ways to reduce your electricity bill.

Frequently Asked Questions

When is electricity cheapest?

Electricity is typically cheapest between 00:00 and 05:00 at night and midday when solar energy production is high. Prices are highest in the morning (6-9) and evening (17-21) when demand peaks.

Is it worth having a fixed electricity price?

The fixed price only applies to the raw electricity price โ€“ not grid tariffs, taxes, or fees. It provides more predictability, but you will likely end up paying more than necessary for your electricity.

How many kWh does a family of 4 use?

For a family of four, annual consumption is typically around 4,400-5,000 kWh.

How much does a laundry load cost in electricity?

A washing machine typically uses 1-2 kWh per load depending on temperature. At 2.50 kr/kWh, a wash costs about 2.50-5.00 kr. By washing at night when electricity is cheapest, you can save up to half.
