Saving money
| Aep raised my rate from 6.5 to 1 point something so I switched to a new supplier I saved money for approximately 6 months then they jump my rate I switched to constellation and got my rate back down however AEP is still crushing me on the delivery charge there should be some kind of a law stopping AEP from their price gouging since everybody is stuck using them for a distributor. With constellation my bill is only about $170 a month but then you have to add aep's $250 distribution charge on top of that and throw in some taxes and lo and behold you're up over $400 every month again. Try paying that on a measly disability check, should I eat or pay my electric bill? | |||

Pleasantly Surprised
| Constellation made it easy to understand to purchase electricity. They offered a competitive price per kWh with a fixed rate for 3 years. A representative called me to ask if I had any concerns or questions. | |||

High Electric Charges 2308 St. Rt. 28 Goshen OH 45122
| Last billing period my bill was for $544.00. Even though this was a colder than normal period, it was way high for this small 2 br house. Was I getting the Constellation rate for that period? | |||
