High power prices make overnight EV charging nearly 150 kroner cheaper

Drivers in western Denmark can save nearly 150 kroner by charging an electric car overnight instead of during the evening’s high-price period, DR reports. Electricity prices are expected to exceed 6.5 kroner per kilowatt-hour at around 5 p.m.
The high prices are partly due to “dunkelflaute,” a weather pattern with little wind and overcast skies that limits the supply of cheap renewable energy. Higher oil and gas prices are also pushing electricity prices up, says Casper Brejnbjerg Olsen, director of subscription sales and customer service at energy company EWII.
EWII calculated the average cost of using electricity between 5 p.m. and 9 p.m., and how much consumers could save by waiting. Its estimates are based on prices in western Denmark.
Cooking in the oven
The average total electricity price between 5 p.m. and 9 p.m. is about 5.45 kroner per kilowatt-hour. An oven typically uses between 2,000 and 3,000 watts, depending on its make, size and type.
An oven using 2,500 watts for one hour would consume 2.5 kilowatt-hours, costing about 13.60 kroner at the evening price. The article notes that the high electricity price does not add hundreds of kroner to the cost of baking a lasagne.
Charging an electric car
EWII estimates that charging a Volkswagen ID.3 with a 58-kilowatt-hour battery from 10 to 80 per cent would cost about 246 kroner between 5 p.m. and 9 p.m. Charging the car between midnight and 6 a.m. would cost about 105 kroner, a saving of nearly 150 kroner. The estimate accounts for about 10 per cent charging loss.
Doing the laundry
A 40-degree wash typically uses about 0.6 kilowatt-hours, while a 60-degree wash can use up to 1.2 kilowatt-hours, depending on the washing machine and programme.
At the evening price of about 5.45 kroner per kilowatt-hour, a 40-degree wash costs about 3.30 kroner and a 60-degree wash about 6.50 kroner. At the overnight price of about 2.33 kroner per kilowatt-hour, the same washes cost about 1.40 and 2.80 kroner respectively. Washing in the evening therefore costs more than twice as much as washing overnight.
EWII’s calculations include the Nord Pool spot price, Trefor and Energinet tariffs, electricity tax and VAT. They do not include the electricity company’s own surcharge or subscription fee.
