Suppose a large power plant generates electricity at 12.0 kV. Its old transformer once converted this voltage to 360 kV. The secondary coil of this transformer is being replaced so that its output can be 740 kV for more efficient cross-country transmission on upgraded transmission lines. If the overall power output is 1000.0 MW and line resistance is 2.00 Ω, what was the power loss, in watts, in the old power lines which left the plant?
