Communication between the apartment building’s Customer Energy Manager (CEM) and Building Automation System enables automated adjustment of the space heating based on market spot prices. As the main control point, the CEM receives price signals and controls the hybrid heating system (district heating and heat pump) to optimise and reduce electricity costs for the building owner

Contracts with consumers allow the retailer to control and shift loads, within predetermined thermal temperature boundaries. Information on the supermarkets’ consumption baseline and flexibility forecast is received via the Aggregation Platform, which communicates with the building CEMs. The optimised flexibility forecasts are used to buy energy cheap and sell activated flexibility at a higher price on the markets
