Welcome to the full documentation on the Brabant energy system digital twin tool.

The tool has been made as a digital twin with elements of a serious game, aimed at policy makers. The main goal of the game is for policy makers to gain insight into the system effects, key choices and trade-offs when creating sustainability strategies for their neighborhoods. We start by modelling indivdual households in neighborhoods and scale-up to show grid congestion and availability of heat sources on a provincial level.
