I hope temperature will become part of the revamp. Currently temperatures are tracked but not really significant.

I would propose that tanks storing liquids draw power based on the difference between their content temperature and ambient. So a simple tank full of water/oil would not need any power drain to just exist but storing 100 degree water ceases to be a free lunch. Mods storing 2000 degree liquid metals could provide their own tank types or factor in the eye watering power demand as part of the cost of the material.
If the power fails or is not sufficient, the temperature drops. Or perhaps fluid loss?

And what do you think would that bring game-play-wise?

Besides that: This is CPU-intensive, cause with every tick every tank in game needs to re-calculated.

Not just every tank. Every pipe too.
