In Europe wind power peaks in the winter so with batteries and hydro to smooth out the gaps you can get a combination of solar and wind to match your demand with relative ease. This does depend on location though, Texas wind peaks in Spring apparently.
A parallel and necessary step (one that has, suspiciously, suddenly become a culture war for the far right in europe) is electrification of heating with heat pumps, which lets you use your existing gas infrastructure to meet winter generation needs.
The problem is that you still need the infrastructure to sustain through longer https://en.wikipedia.org/wiki/Dunkelflaute . It does not matter if you have to pay the fixed cost of the infrastructure to use it once or ten times a year. If we only need it every few years things will probably get worse since politicians might try to skirt it and hope nothing will go wrong during their tenure.
I am not arguing against intermittent energy sources but we need to address these problems.
While related insofar some electricity inevitably gets converted back into heating, I don't think its really relevant to this discussion which is explicitly about electricity.
The winter peaks in gas and electricity are driven by heating demand. Electrification of heat combines the two and will make winter electricity peaks even peakier.
So anything that reduces that heat demand at a lower cost is a relevant fix, this includes heat storage, district heating, general efficiency and insulation improvements etc.
Since we're talking about Texas, you could just come up with a way to store all the natural gas we flare each year. Which is a huge amount. Or you could just sell it to places that could use it.
