Correct.
I mentioned batteries because although you claim to have an interest in them you forgot about them when you said,
"First, neither wind nor solar runs dependably around the clock, 24/7, as a coal- or gas-fired or nuclear plant normally does. Hence while the 3 cents/kWh solar price may be half that of a coal or gas plant, it must be backed up in one form or another so it is an apple vs. orange comparison"
Factor in batteries and the above is nonsense. You seem to understand that so must have chosen to leave it out.
