Electricity isn't the issue, several countries have re-opened coal plants to deal with that (also from what I understand the nuclear plants can't just be turned back on, they are several stages through decommissioning and were already reaching the end of service without refurbishment, etc.).

But natural gas itself is still required for industry and domestic heating in most of Europe, and that cannot be solved in the 3 months remaining to winter.
