You are in a thread saying that shutting down nuclear was a mistake because they'd have to burn coal to make up for it. At the same time you are saying that forcing new installations (and repairs to a certain extent) to use heat pumps instead of gas starting next year putting even more stress on the grid is a good move?
The "grid" wasn't "strained". The main source of cheap gas got strangled due to a war. Most of it was used in home heating and industry, neither of which nuclear would help with without more electrification.
