@Vinbert :
Ouch! Yeah the constellation bill will be better. I took a look and the other deals are with low rated companies I never heard of or were more expensive.
I'm not sure about locking in that rate for 3 years but it is pretty good for this current market.
2 years seems to be the sweet spot for lowest cost nowadays.
I have looked into Constellation in the past would not have a problem going with them.
I have worked with, Startex, Gexa, Discount power and now Cirro. All are about the same as far as interface. I set them up for automatic bill pay on a credit card (cash back card) and watch the monthly bill emails to make sure things are OK. If there is a problem I can always dispute the charge on the credit card. My usage is down to about 900kWh in winter (Gas heaters) and a peek of 2500kWh this past summer with a 4 ton and a window unit going during the peek heat of the day. Bill never exceeded 300. so I was happy.
