I'm new to the game and have checked my 10 biomass burners and 12 coal generators. They're all producing at 100%.

That should be 1200MW of power that it's producing

10*30 and 12*75.

My capacity on my power grid is 1200MW however, it says I'm only producing 900MW.

Am I misunderstanding something, or what have I done wrong?
