Business model

• For the investment in BDH, the PPPP model will be used.

• Municipality of Šentrupert will take part in establishing of the energy cooperative, into which it includes local stakeholders (citizens of the Šentrupert and local private companies)

• The biggest interest for membership in the cooperative would be on the side of forest owners, who would for exchange for using the heat energy from the system of remote heating, supply the wood for making wooden chips.
