  Just wanted to say Thank you for dependable and affordable electricity. You treat your customers well, in a time when customer service is terrible yours is not, it's great. You seem to care about your customers and that means a lot to me. Again thank you!

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.
