A Swedish homeowner was billed 2,242 kronor – approximately $215 USD – for a single hour of electricity consumption, a case highlighting the financial impact of a new electricity tariff structure taking effect across the country. The charge, reported by Börskollen, underscores growing concerns among electric vehicle (EV) owners about the rising cost of charging during peak demand.
The new tariff, known as the “effektavgift” (effect fee), shifts the financial burden of electricity network costs from total energy consumption to peak demand. Rather than being charged solely on the total kilowatt-hours (kWh) used, households will now pay based on their highest power draw during a billing period. This means simultaneous employ of high-energy appliances – such as heat pumps, ovens, and EV chargers – can significantly increase costs.
Mats Norrman, a product specialist at Svedea bil, a Swedish insurance company, explained that the timing of electricity usage is now critical. “Many EV owners charge their cars immediately after work, often at the same time other energy-intensive equipment is running,” Norrman said. “This behavior can quickly lead to a high peak demand, which in turn increases network costs for the entire month.”
The effect fee is being implemented as EV adoption continues to rise across Sweden. According to a Svedea analysis, the number of EVs is increasing in many regions of the country, indicating sustained consumer interest. However, the new tariff structure poses a challenge for EV owners seeking to manage their electricity bills.
The impact is particularly acute for homeowners. Dagens.se reports that villa owners with EVs are especially vulnerable to higher network fees if charging coincides with other significant energy demands. A typical home EV charger can draw 7-11 kW, adding substantially to peak load.
To mitigate the impact of the effect fee, Norrman recommends scheduling EV charging during off-peak hours, such as overnight. He also suggests utilizing a charging station with load balancing capabilities. Load balancing automatically adjusts the charging rate based on the household’s overall electricity consumption, preventing a surge in peak demand.
All Swedish electricity network companies are required to implement the effect fee by January 1, 2027, though many have already begun doing so. The new system is designed to encourage more efficient energy use and reduce strain on the electricity grid, but the financial consequences for consumers, particularly EV owners, are becoming increasingly apparent.
