The most demanding aspect of this simulation was clearly handling the complex electrical grid management. The maker tackled this by incorporating detailed physics into the system, ensuring that cable sizing is critical, and that an overloaded wire will burn out. This detailed approach gives the game immense realism. The player must physically place junction boxes and lay cables on their land, and the simulation accounts for the actual sun's angle, panel facing, and shading, along with variable weather including rain and overcast conditions.
Construction details that stand out include the wide range of battery types available, which stretch from simple home batteries and DIY racks to complex vanadium flow batteries and BESS containers. Furthermore, the game features a power map that tracks every network and its load, while a separate management screen tracks all battery components. The maker has also modeled appliance usage realistically, with each signed-up house simulating appliances like heat pumps and EV chargers.
Despite the depth of the simulation, the project is not yet complete. The maker has stated that features like snow and winter aspects are planned for after the 1.0 release, representing an open question for the current version of the game. It is worth noting that while the maker is a software engineer, most of the game assets were purchased rather than created from scratch. The visual style of the stats screens is reminiscent of Factorio!
