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.

If you have any questions, please call us at 877.226.7427.


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.
