I've been testing turbine-setups in single player (creative) with adjusted config files because my Vision needs absurd amounts of power (and unoptimized turbines apparently) and I'd like to minimize the amount of turbines required. ( http://pastebin.com/BwYKXgYK relevant option is: "D:powerProductionMultiplier=10.0") I'm using the OMP-i modpack.

As the screenshot shows, the power generated is quite a bit higher than one million, but the maximum output is still a million. (Tested with cryo-stabilized fluxducts and the enderIO powerbanks (big enough to have a limit above a million rf/t for input/output).
When I look at the Turbine Control screen, the Energy Buffer flickers from full to empty and back when it charges the energy-bank.
Is it intended that the maximum output is restricted by the energy buffer or is this a bug?

e: It also seems like the energy-values aren't truncated (I've seen some screenshots with KiRF), is this due to the edited config file?
