Many customers were sent a letter stating their account was automatically credited through our Big Heart Grant. Unfortunately, an error caused this letter to be sent to some customers who did not automatically qualify for the grant. We are working to notify customers who received this letter in error, and sincerely apologize for the confusion this has caused. If you received this letter, you may still be eligible for the Big Heart Grant. Call Customer Service at 888-522-1130 to find out if you qualify. For a correct account balance, please refer to your next Cascade Natural Gas bill or log in to your CNGC online account here.

Need help? Agents are online from 8 a.m to 3 p.m. PST to answer your questions.
