It doesn't have to incentivize new technologies. It could just as easily incentivize new business models. Imagine a laundromat that sells "FREE DRYING" during the day. Heck, I bet you a lot more people will do laundry during the day time. Similarly, power companies can give incentives for more day time power usage. A lot of people already follow night time power usage today so its no reason to think it wouldn't work.
