No. You're right that the program is (currently) voluntary; I haven't volunteered, not least because I run the AC at 76°, I have and know how to use ceiling fans, and most months the bill barely breaks $150 if that - my house is 140 years old, and while that's not enough especially in Baltimore to say that its survival proves it is well designed, it is well designed.
This is targeted at two groups of people: fools who paid far too much for far too little and ended up house-poor in a place built last year that doesn't know how to stay cool, and folks for whom $100 a month makes a huge difference. One of those groups has my sympathy, especially because I expect they'll be first and hardest hit when these programs cease being voluntary because the state isn't investing enough in generation capacity and the city isn't investing enough in grid maintenance.
