Commodity Pricing Option
Explaining the Energy Charge
There are two types of charges on your Maine Natural Gas (MNG) Bill; “delivery charge” and “energy charge”. For more information on the delivery charge please see rates and tariff page.
Maine Natural Gas offers a single pricing for the natural gas we supply to you, detailed below. This reflects the cost for MNG to purchase natural gas on your behalf itemized on your bill as the Energy Charge. Energy Charges are a direct pass along to the customer and reflect the purchase price that MNG paid.

Index Price Option (IPO):
For all customers this will be their default supply price. The IPO is based off market pricing, which tends to rise during the heating season and fall during non-heating months. The IPO pricing is adjusted each month based on changes in the commodity price of natural gas and is calculated based on the New York Mercantile Exchange (NYMEX) closing settlement prices.
Current IPO
Current IPO for June 2026 is $0.9206
Effective April 1, 2026, an Interim Cost of Gas Reconciliation Adjustment went into effect resulting in an increase of $0.2552 per therm for the Cost of Gas for the months of April 2026 through August 2026. This adjustment is to partially recover higher than expected gas costs incurred during the winter months, largely driven by colder-than-expected winter weather and higher supply costs. The current IPO (reflected above) includes this adjustment.
On May 15, 2026, Maine Natural Gas (MNG) submitted its annual cost of gas adjustment filing to the Maine Public Utilities Commission (MPUC). Customers have the right to participate in the MPUC proceeding. Please reference the information in the Company's notice of proposed changes. If you have any questions about the cost of gas adjustment request, please call our office toll-free at 1-877-867-1642.
