> the big issue during winters is when there's cold air high pressure systems we get neither sun nor wind

Wind does better in the winter.

See eg here for Canada monthly stats: https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=251000...

Also, wind does better at night than day, which may be related or not.

I think the point is that winter can create periods where there is neither adequate wind or adequate sun. Having strong wind production at some times will only be good if there's a way to store the excess. That's exactly what this project does and I believe that was GPs point.

And in Finland: 60% of Finnish wind energy 'collected' in the winter months (Oct-Mar)
