We just got a partial bill for our new house. Most of the time was spent waiting on blinds (so sun just blasting into the house in every room) along with lots of other factors that have our usage higher than will be typical at 3,119 kWh and our bill was $146.66, which is right at about $0.045 per kWh.
More importantly, they handled our move with absolute ease.
My previous plan expired at the end of June. We moved from our old house to new house mid July, so I had them:
1. Set up my old house and terminate service with the previous provider
2. on 7/15, start service at new house
3. on 7/19, end service at old house
No hiccups or problems at all - I half expected to find out that my old house was still being billed or something, but it went very smoothly. And I set all of this up at the end of June, meaning I didn't have to call them every step of the way.
I've been more than impressed. Definitely worth the $10/month to not have to worry about it.
