Pennsylvania

In 2024, the PA PUC got 7 complaints from homes about Constellation for electricity sold as Constellation Energy Power Choice, 15 complaints for electricity sold as Constellation New Energy and fewer than 5 complaints for natural gas. It doesn't rate Constellation against other companies, so we can't say if that is many or few for its size.Show
Electricity sold as Constellation Energy Power Choice, 2024
7 complaints named the company. In 5 of them, it was the main company the complaint was about.
Electricity sold as Constellation New Energy, 2024
15 complaints named the company. In 7 of them, it was the main company the complaint was about.
Natural gas, 2024
Fewer than 5 complaints. The PA PUC doesn't give the exact number below 5.
Name in the report
Constellation Energy Power Choice (f/k/a MX); Constellation New Energy; Constellation Energy Gas Choice

These count complaints and requests for help with a payment plan that homes brought to the PA PUC in 2024.

The PA PUC says companies differ in size and it doesn't know how many customers each one has. So a high number doesn't by itself mean the company broke the rules.

We checked these on October 13, 2026.

To complain about Constellation in Pennsylvania, call Pennsylvania Public Utility Commission (PUC) at 1-800-692-7380.
