50MW is not enough , i know its supposed to help build factories but how i am supposed to use them if there is 50MW limit , whos hardly enough to place few things with production modules :C , i wish there would be upgraded more expensive factories who at least extend that to 150MW , or 3 tiers 50 100 and 150

For the last few versions you can easily configure that in the config.lua of the mod :)

"-- As usual for configs, playing multiplayer will require all players to have the same config as the server.

-- How much power a factory or power plant can store
-- Note: If this value is set too small relative to the power limits, then this will lower the effective power limits.
factorissimo.config.power_buffer = "10MJ"

-- How much power can enter a factory
factorissimo.config.power_input_limit = "50MW""
