By 1 January 2027, all Swedish electricity grid companies must introduce power tariffs in accordance with requirements from the Swedish Energy Markets Inspectorate (Ei). Large 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 only an hour, can affect the cost of an entire month.
Grid companies' different models and the consequences for property owners
Ellevio bases its power charge on the highest power-demand hours per month, E.ON focuses on peak-load hours during the winter season, and Vattenfall is working towards similar models. For commercial properties, this means that systems such as ventilation, cooling, heat pumps and electric vehicle charging can create peaks with significant financial consequences.
Why real-time metering is becoming crucial
Once a power peak has occurred, it is often too late to act. To be able 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 drives the peaks and to act before they have financial consequences. With power tariffs, fast and detailed metering data is therefore 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 in M-Bus locally within the property. It therefore offers a faster and more detailed data source than the grid companies' own APIs. With 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 are enabled.
