That doesn't help during peak hearing hours overnight and also doesn't help for multifamily.
My comment was not directed at the gas ban discussion specifically. I was just thinking about the connection between the gas ban and this push in NYC to get people to decommission their gas boilers/furnaces in favor of heat pumps. I don't believe the program covers multifamily/commercial/etc anyway, so that issue is less relevant unrelated. The point was that the program as is would've been smarter with a solar tie-in.
As far as solar covering all the HVAC loads, of course it doesn't. [While we're at it though, since when is overnight peak heating hours? Isn't it standard to set your thermostat a few degrees lower overnight? If you told me 4-12 in the winter or something like that, I hear that (and your point still stands).] But wouldn't the grid itself - ie the infrastructure - be fine to handle winter overnights, since presumably in today's gas heavy heating environment that's a low load time for electricity? If the question is about source of that electricity, of course in the long term NY would need to branch into other renewables, and/or explore all of the emerging grid-level storage ideas. It's definitely putting the cart before the horse to ban gas before all that is in place, but that's the way this breed of progressives rolls.
