Level Pay Plan

The Level Pay Plan makes budgeting for your bill easy by allowing you to make equal monthly payments. To determine your Level Pay amount, we estimate your annual gas consumption, using actual usage history when available, and divide that amount into equal monthly installments. Then, we track your actual usage and make adjustments as necessary through the year. Check our Level Pay Brochure for more information.
