The preliminary study is a collaboration between STUNS, Morgongåva Företagspark, Sala-Heby Energi and Uppsala University. As the call points out, new ways are needed to share energy within areas in more resource-efficient ways, while the interaction with the existing electricity network needs to increase. In this pre-study, we want to study the technical, economic and sustainability conditions for a smart energy system in Morgongåva Företagspark. The goal is that this pre-study can lead to decisions about future initiatives that are implemented in practice. These efforts will make Företagsparken and Morgongåva society more self-sufficient and less vulnerable to interruptions in electricity and heat supplies from overhead systems.
