The backup capacity is cheap (in capital cost) compared to nuclear providing the same output. Like, an order of magnitude cheaper. Combustion turbines are remarkably compact and inexpensive for their power output (this is why they power our aircraft). It's wonderful what happens to machinery when you can reduce the need to transfer heat across fluid-solid boundaries. Rocket engines are an even more extreme example of this.
Rooppur Nuclear Power Plant cost $6 per Watt of installed capacity over the projected 50 years of lifetime. Simple natural gas turbines (not combined cycle) cost around $2 per Watt over 50 years in just capital costs. This doesn't take into account the cost of the fuel, or the magic infrastructure to produce, store, and deliver hydrogen.
I'm taking Rooppur Nuclear Power Plant as the base for comparison because it's an example of what you can do, when you have a "mass produced" design that you can just quickly build.
That's funded by a loan from the Russian government, not from private financial markets, so we can assume the rate is below market. The actual cost when real risk penalties are included (as they must be for an accurate cost) would be higher.
I also doubt anyone is going to be buying Russian nuclear power plants in Europe anytime soon. The strategic risk and associated cost (as seen with importing natural gas from Russia) would be far too high.

Not much higher, though. Russia makes money on these contracts. South Korea has

Of course. I'm not suggesting that Russia should be relied upon for ANYTHING at this point. It should be as isolated economically as possible.
I'm just using this as an example of what you can do with a streamlined construction pipeline for plain old PWRs. No fancy new technology, no breakthroughs, just regular old good project management.
