Suggest adding a 6.0MW and 18MW multiplier options as for PyHM 2.4MW seems cheap. Seems to be a 3 line change in this mod (and corresponding in fluid memory storage), works as far as I've tested.
In settings.lua, replace line 7:
allowed_values = {'0W', '60kW', '180kW', '300kW', '480kW', '600kW', '1.2MW', '2.4MW', '6.0MW', '18MW'}
In shared.lua, replace line 69:
['2.4MW'] = 40000,
['6.0MW'] = 100000,
['18MW'] = 300000
