I've been using OhmConnect for a while now and its ok. Our usage is pretty low even under the worst scenarios, so our ability to lower it is minimal. Looking through our history of Ohm Hours, our "expected" usage ranges from .386 kWh - .655 kWh (depending on day/time), and our actual usage when we cut back goes down to .195 kWh - .38 kWh. We typically earn 40 - 60 points per Ohm Hour, which is the equivalent of $.40 - $.60, so we're hardly going to get rich off this. But the initial sign up bonus we got was $20, which we could cash out right away, so I think its worth it just to sign up just for that. Right now I'm up to about 1700 points so we'll be able to cash out another $20 soon (I think we got another bonus in there somewhere). You can disconnect from the service easily so there's not really any downside to doing it.
But I do like it from an environmental standpoint, knowing we're able to do a little something to help lower demand at peak times and hopefully minimize the need for less clean means of energy production. What we do to save during Ohm Hours is just turn off the tv and computers and any extra lights, and either go out for an hour (hubby usually hits the gym) or just read or do yardwork or something. I find it good to unplug for an hour every now and then anyway.
One thing to note is that if you go over your expected usage for an Ohm Hour you will lose points, but you have the option to Opt Out ahead of time and just get 0 points regardless of your usage, so if you know you can't unplug for that time you want to make sure you click the opt out button.
Here's my referral link if anyone is interested in trying it out:
