I REALLY don't want to raise my energy tech to 15 to test this. Highest is 14 so no-one can tell us- unless they deliberately raise it? You know you want to ;) Edit: if reactor values are all at level 5 energy tech up to 15 then we substitute in energy tech 5 and the formula given in the description...

Are you sure your energy tech level is 11? Because those numbers perfectly match what my formula gives for level 10 energy.

The equation has been quoted wrong. I'm guess that is because it was changed at some point and not updated in the description.

The correct equation is:
Energy = 100 * {Reactor level} * (1 + {Energy Tech Level} * 0.01) ^ {Reactor level}

I'm just a genius with too much time and not enough Uranium...
