Fun fact: it's not just small grids that run on steam - Munich's steam heating dates back to 1908 and since 2022 it's being reworked at massive expense to hot water to better accommodate geothermal and other renewable forms of heatpump based generation because these sources cannot get hot enough to produce supercritical steam [1].
