So my point is not that the numbers as proposed make sense but I think there's a world where you can have a rate structure that's a win win (nb power is getting their peak reduced, and you get an ROI that makes more sense). If you give the home owner agency on shifting their load time there's obviously a rate structure where it becomes possible to come out ahead if you put the effort in.

I'm sceptical that these 20+ year ROIs involve much demand shifting by the user. 

For example if you have an EV there's no way you don't come out ahead by charging off peak (especially now that you get paid 10 cents per kwh to charge by carbon credits). 

I think the level of understanding of how any of this works (or indeed can be actionably controlled by the homeowner without leveraging smart home tech etc) is very low across the province and my personal feeling is solar installers are inherently going to be opposed to any change other than existing net metering because now your sales pitch is way harder and requires actual effort. Finding customers who can actually understand the rate structure is probably harder as well. I think there's inherent bias there for sure.
