There's nothing "wrong" with the units, besides that it is easy to get confused, evidenced by GP calling the turbine "7MW(h?)".
If you want to compare, however, you will have to convert to common units, and I at least find it easier to use watts and joules than watt-hours/second and watt-hours. By all means convert to stationary-bike-hours and big macs or whatever unit at the end but calculations are easier in the SI units.
Hubble's constant is expressed like that because it is a nice unit for the math.
