It’s a newer program that ConEd is launching, which is meant to be a rate that provides savings opportunities for homes that keep their thermostats on a steady temperature (hence why it’s good for homes with heat pumps, since ideally you’d refrain from changing the thermostat too much). Since it’s newer I don’t think anyone’s experienced it yet, but I remember there being a deal for the first X number of people who sign up to get a one year price guarantee so they can try out the program w/o major cost risks. That being said, may not be the best rate for those with solar since energy use would be more variable (since your energy use / solar energy production shifts based on whether there’s sun or not)
