Natural gas supply rates change monthly based on current projected 12-month market prices. The revenues collected compared to actual costs incurred by NWE are trued up on an annual basis. NWE purchases wholesale natural gas from producers and passes the cost directly to customers without markup.

Effective January 1, 2017 the supply price does not include the supply tax.
