10% is a lot. I'm not a utility engineer, but I would think they would lose less than 10% of power in the whole system.

it depends on the voltage at which the lines are running. The high power main lines use very high voltage so the loss of power is minimal. While smaller wood pole lines would lose more.
But for an broad estimation to your question. High power lines lose virtually no power loss over the given the voltage and distance it runs at. So there is no exact mileage

Nick Gs answer is not stictly correct.
Power line losses are the I²R (watts) losses due to current and resistance of the overhead line. Voltage does not have any bearing on the losses. It can be a very high voltage line or low voltage..... a wood pole line or towers
Nick is correct stating that there is no method to calculate a line loss distance of 10% as the resistance/current varies with the size, loading and P.F of the line.
