Easy to switch to Constellation

(5 / 5)

  It was easy to switch to Constellation on the Mass Energy Ratings website. Simply read the listings and pick an energy provider that services your area. It was that easy.

Energy Provider Selection

(5 / 5)

  Selecting a provider was virtually seamless for Electricity. You choose your plan, go through entering the info, submit, and wait to hear back. You get a confirmation from both Constellation and your supplier to confirm your selection.

  I have not been with Constellation Energy long enough to really rate them. I haven't even paid my first bill yet. But they certainly were professional as far as setting my account up.

Best Rate Available At The Time

(5 / 5)

  Constellation had the lowest rate at the start of 2022 when Eversource's standard rate increased. There were no enrollment or cancellation fees. It was the best deal at the time that my previous alternate electricity supplier's contract was ending. Although this Constellation plan lasts for a longer term than I wanted, I can exit the plan at any time without penalty should a different supplier offer a lower rate.
