Not in any realistic sense. This report

just mashes together a PV array with about an hour of storage and quotes a price for that which is low and is certainly not going to get you through the night.
So many things drive me nuts about that report and the discourse around it that, I think, contribute to people talking past each other. For instance, quoting one price for solar energy is nonsensical when the same solar panel is going to give much more energy in Arizona than it is in upstate New York. The cost of a solar + battery system is going to be different in different places. In upstate NY we deal with a lot of retailers that are based in places like Bentonville, AK who just can't believe you might need an electric space heater in late April or otherwise your chickens might die. Since 95% of the world's population lives in a milder climate it's no wonder our needs don't get taken seriously.
The intermittency problem involves: (1) diurnal variation (overnight), (2) seasonal variation (do you overbuild solar panels 3x so you have enough generation in the winter or do you invest in very long term storage?) and (3) Dunkelflaute conditions when you are unlucky and get a few bad weeks of weather.
I've seen analyses of the cost of a grid that consider just smoothing out one day, but not one that covers seasonal variation. (So much of it comes down to: "how many days of blackout a year can people tolerate?")
With a significant overbuild or weeks worth of storage capacity costs are not going to be so favorable against nuclear energy. The overbuild offers the possibility that you could do something useful with the extra power but it is easier said than done because "free" power from renewables is like a free puppy. You have to build power lines to transmit it, or batteries to store it, or you have to feed it into some machine whose capital costs are low enough that you're not going to worry about the economics of only running it 20% of the time. (Go tell a Chemical Engineer about your plan to run a chemical factory 20% of the time and that's probably the last time you'll hear from them.)
