This is an interesting idea for a mod, but I would love an option to change power production – in my case, to 2 MW instead of 3.6 MW.

I also think there are ways to make this mod more interesting. Perhaps it could require four steel steam engines per steel boiler rather than two, or perhaps the boiler and engines could be larger in size. Some new or at least adjusted sprites to differentiate them would be nice as well.

If you want more challenge crafting them, just play with Krastorio 2 and/or AAI Industry, both of these change recipes (Krastorio make it require steel cogs, AAI Industry make it require electrical engines)

Power production matches vanilla (and most modpacks) scaling, where Stone -> Steel furnaces double the production speed, so does the steel boilers and steel steam engine
