What you say is true as far as you go.

But another aspect of it is the utility must buy equipment rated for the MVA
while only the MW portion of the apparent power generates revenue (in most
cases).  So they also have a larger capital outlay for this 'oversized'
equipment that has to be funded.  They wouldn't need larger equipment if
they were able to have only unity loads.  This goes into the considerations
for pf correction at load-centers/substations instead of supplying the
MVAR's from generating stations. (pf correct at load-end, or upsize
transmission *to* the load-end by 20-40%).
