We need to place more emphasis on the consumer side of Demand Side Management (DSM) if district heating customers efficiently and significantly should contribute to the sustainable energy system. HOFOR is testing the flexumer concept, where customers voluntarily contribute to system flexibility. To implement the full potential of flexibility provided by flexumers, a combination of revised legislation, new technical solutions, and new customer products is needed. So far, the project has proven quite successful, being able to activate up to around 8 MW of flexibility through voluntary agreements with 20 large building owners and 140 buildings. The system benefits will be tested during the heating season of 2025/2026 FROM CONSUMER TO FLEXUMER
