The system is connected to HFAB’s central operating and monitoring system for control and regulation purposes and is prepared for various future operational strategies, depending on the price model for district heating and how the price of energy develops.
“We think it is important. The only thing we can say about the future is that we do not know what is going to happen, but we are prepared for most things,” says Ulf Johansson, HFAB HVAC and energy coordinator.
“We are now preparing to supply our properties with solar power within a few years.”
