Conversion to Constellation

I was amazed with how easy it was to convert my electric service to Constellation. They not only had one of the lowest rates, but also the online process was quick, very easy, and I received emails explaining my account had been created and the cancellation to my previous supplier.

Very Pleased

So far, things are great. The only things I found mildly annoying were: 1) The letter they sent advertised a lower rate, but "my area" was not eligible. 2) The website is not easy to navigate. Otherwise, I'm quite happy.

Constellation is a good company that followed thru with their promises.

I have had no problems with Constellation since I signed up with them. Their rates were good and were exactly what they promised. Just waiting to see how much of a change there will be after my first year!

Satisfied customer

Constellation communicates with their customers each month and gives them a comparison of the amounts of electricity used from month to month. They also give suggestions on how to cut power costs in your home. I have been more than satisfied with their service. They also began reminding me several months ago that my contract with them is about to expire and offered options to stay with them or find another provider.

Electric Bill Still Higher Than Expected

While I am glad to have received a better rate with Constellation, for a fixed 6-month period, no less, I will continue to search for a lower rate because my bill is still considerably higher than I had hoped, despite having gotten new weather stripping and additional insulation added to multiple areas of my house in the past few months.

Switched before old contract expired

The only thing that concerned me, that I was switched immediately before my contract expired with Tri- Eagle. Which caused me to pay a pentality. Which was probably my fault.

Just starting w/ Constellation

Since our present electric company's rates have jumped dramatically we decided to try another company. I can not
share Constellation's business procedures; we Just became Consellation consumers - however, I will say that the information that was available for us to 'compare' their company w/ the others was extremely helpful. The procedure was a snap to sign on. I only hope that the rest of our contracted time will be as 'comfortable'.

Worst company to deal with

I found out today that I am locked into a 5 year contract with this company!! Would NEVER have signed with this company had I been told that up front. Was charged $2,000 for an early cancellation fee! Extortion! Just my opinion , but buyer beware!!!

Signing up was no problem. They sent us an order number and confirmation but as far as we know we are not getting anything from constellation. My last bill did not reflect constellation. This does not make us happy!

Bait & Switch

I your advertised rate for Constellation and signed up for it. When they sent me my confirmation, a higher rate was given. I immediately emailed them for an answer (and to have a legal copy of the document on hand). I got a canned reply saying I would have an answer on 2-3 business days. I had to call them 2 weeks later since I received no other reply. I cancelled their service since they did not answer me and they did a "bait and switch" on pricing. I though I was signing up for .481/CCF but they gave me .499/CCF

Very poor customer service.

Will not partner with People's Gass

I attempted to shop competitively for gas prices and attempted to switch to Constellation, who I've used in the past. However, they don't partner with People's Gas anymore and so the switch never took place.
