By 1 January 2027 at the latest, all Swedish electricity grid companies must introduce power tariffs in accordance with requirements from the Swedish Energy Markets Inspectorate (Ei). Major grid companies such as Ellevio, E.ON and Vattenfall have already begun introducing models in which grid costs are determined by the customer’s highest power demand—not solely by energy consumption. Power tariffs mean that a brief peak, sometimes lasting only one hour, can affect the cost for an entire month.
Different grid company models and the implications for property owners
Ellevio bases its power charge on the highest power-demand hours each month, E.ON focuses on high-load hours during the winter months, and Vattenfall is working towards similar models. For commercial properties, this means that systems such as ventilation, cooling, heat pumps and EV charging can create peaks with significant financial consequences.
Why real-time metering is becoming essential
Once a power peak has occurred, it is often too late to act. To distribute loads, control systems or pause equipment, insight into the property’s current power demand is required—not a retrospective view much later. Real-time metering makes it possible to understand what is driving the peaks and act before they have financial consequences. With power tariffs, fast and detailed metering data therefore becomes a prerequisite for active energy management.
PiiGAB HAN-P1 Converter – a solution for faster control
PiiGAB HAN-P1 Converter provides real-time data directly from the property’s main electricity meter via the HAN port, which can be read out over M-Bus locally within the property. It therefore offers a faster and more detailed data source than the grid companies’ own APIs. With the PiiGAB HAN-P1 Converter, property owners receive second-by-second information to see how the load is developing in real time and adjust systems before a peak occurs. By integrating the data into a BMS or energy management system, proactive load management, more consistent operation and lower costs become possible.
