From January 2027, all electricity network operators in Sweden will be required to introduce a new pricing model in which the grid fee is partly based on households’ highest power peaks each month, rather than solely on total electricity consumption in kWh, as is common today. The new power tariffs will affect owners of single-family homes and provide an economic incentive for households to shift their electricity use over time and reduce their power peaks during periods of high grid load.

This project will examine how the new power tariff impacts electricity costs for homeowners and which opportunities they have to adjust their electricity consumption to reduce their expenses.

We will provide an overview of how the introduction of power tariffs will affect electricity costs for Swedish single-family homes with electric heating through a heat pump. Through simulations, we will analyze how these costs vary depending on a range of factors, such as geographical location, grid and price area, house type, and whether the household owns an electric vehicle. We will also analyze the opportunities households have to influence their costs by controlling major electricity loads such as the heat pump and electric vehicle charging, or by using energy storage systems to reduce their power peaks.

The project will contribute to an international exchange of knowledge through participation in the new collaboration project on flexibility within IEA Heat Pumping Technologies.

Our goal is to generate knowledge that helps electricity network operators design grid fee pricing models that reduce grid load during high demand periods. The project will also provide insights that support the development of new products and services for managing electricity use in single family homes, thereby lowering electricity costs through smart load control.
