Power system: substations

Substations could add even more depth to the electrical power system of the game. Substations would be small buildings with a certain low voltage supply radius. Buildings which require electrical power would need to be placed within the supply area of a substation. Different tier levels of substations could come with larger supply areas. Power generators would also need to be placed in supplied areas from a substation. If even more realism is wanted, substations could have a power limit, forcing players to built multiple substations with multiple transformers next to big power plants or energy intense factories. It would be an option to require overhead high voltage power lines between substation (Highrise city does this), but it requires more complicated graphics and I m not sure if players would enjoy this aspect. If no overhead power lines between substations are implemented, all high voltage connections simply would be invisible underground cables (in reality possible but 3-10 time
