I suspect your turbine is built incorrectly in that case. It sounds like you have too many turbine blades to support the coils you're using. IIRC, the program will basically push the turbine to the floor and run it as fast as it can during the calibration. It only will decrease the steam flow rate once it has calibrated against the maximum energy production possible. If the calibration causes it to go overspeed, then the program stops and errors out, as you see. So you should either reduce the number of turbine blades to bring it more in line with the coil(s) you're using, or add more coils to
