BRITE is carrying out a pre-feasibility study for the development of a heat network in Brussels North District. The heat demand and the potential green heat sources will be mapped out. The final Levelised Cost of Heat (LCOH) will be assessed for various scenarios, defined both in terms of spatial deployment and exploited heat sources. Such an LCOH takes the investement and the operating costs into account. A user-friendly tool will be delivered to the authorities to replicate such a pre-feasibility study to other districts based on the developed methodology.
