Reading the comments, it would seem most everyone here thinks that the usefulness of the steam is done when it gets used to turn a turbine at high pressure.
The steam can be used for much more than once. In the 1800’s and early 1900s when steam ran trains and ships, they built double and triple expansion engines that took the energy of the steam two and three times before it was done. It doesn’t need to be one and done. And when the energy is done being harvested for power generation, it can used for other things. Engineers today aren’t dumber than the ones in the 1800s.
I can remember a small rural Minnesota town that had their own coal fired electric plant. (Built back before the REA was a thing). They took the left over steam from power generation and then piped it to around 200 homes in the town and heated them with the leftover steam. While a bit costly to install, it was dirt cheap to run. Those homes lost all that when the power plant was shut down and they had to switch to either natural gas, fuel oil, LP, or electricity.
So don’t get hung up on just the power generation. Think what could be beyond that point.
Municipal steam networks are still operating today.
For new infrastructure, Electricity is just so good-enough, that it is hard to justify building out partial alternatives like steam pipes. But where we already have them, they are still useful.
