No matter which "provider" you choose New York State has the second highest cost for electricity in the Nation, right off the top. There is no secret in this God forsaken State to save any money you can't. I know people who have switched to "alternate" plans such as you mention. Lots of them around now. I truthfully don't know anyone who, after at least 3 months is happy with changing things around.
A rich person is not the one who has the most but the one who needs the least.
