There are many variations in Power Plant configurations and design, at the most basic of levels, a fossil fuel is combusted to produce steam, which then rotates a turbine that drives an alternator, to provide electricity.
Power Plant is a complex arrangement of pipework and machinery with a myriad of interacting control loops and support systems.
A Turbine Hall is typically extremely loud, and in the case of steam cycle plants, like here, it’s also hot.
Please, welcome the 1960s fully functional analog machinery miracle!
