‘You haven’t factored in the loss while the electricity passes through power cables from the plant through the grid.’
About 5%.

From what I understand, it is MUCH higher than 5%

The 5% comes from a european study I saw years ago.

This is what Wikipedia says:

Transmission and distribution losses in the USA were estimated at 6.6% in 1997[10] and 6.5% in 2007.[10] In general, losses are estimated from the discrepancy between energy produced (as reported by power plants) and energy sold to end customers; the difference between what is produced and what is consumed constitute transmission and distribution losses.

So, yes losses are more that 5% but not much higher.

New cogeneration plants can reach 60% effiency, even with a 10% loss in transmission, that leaves the power plant operating at 50% at your door step.

Traditional automobiles are about 10% efficient over all which give a rechargable electric cars two advantages. One, over all effiency from fuel to pavement would be higher and second, that energy can come from cheaper domestic fuels.
