Any electricity demand that can be modulated is good for renewables.

Big plants have been doing this for decades, even before renewables were a thing. The new thing is computers making it cheaply automatable and networked so that e.g. a fleet of cars can organise their charging schedule via the internet.

But rising electricity demand isn't a problem for renewables and climate change, it is in fact a required and desirable part of a virtuous cycle.

So build the Green Ammonia plant and build the renewables to power it 100% of the time but have the option to turn your electrolysers down and sell a small percentage of that to the grid when market prices let you profit from that. It's a win-win-win, less gas peakers, more green electricity and green hydrogen.
