Sweden has introduced updated residential grid tariffs which significantly change how electricity costs are calculated. Consumers are now charged not only for their variable energy usage—often based on hourly spot prices—but also for the highest power demand (kW) they incur during peak intervals. This shift puts greater financial pressure on consumers to limit both their energy use and their maximum power draw.
In this context, our EMS SmartgridOne, that controls flexible assets—such as batteries, EV chargers, and heat pumps—must now aim to minimize total electricity cost, which includes both consumption and capacity charges.
Our EMS is already equipped to handle these new tariff structures. It employs an optimization algorithm that considers both energy pricing and peak power constraints. Specifically:
