Gas supply and balancing service options for IGD-1 customers
Purchase gas supply directly from MGE or from an alternative (third-party) supplier.

  1. Natural gas supply from MGE: MGE purchases natural gas, contracts with interstate pipeline companies to transport this supply to our local distribution area and balances purchases with your usage using pipeline storage and balancing services. Learn more about: How MGE Buys Natural Gas

    Natural gas service is provided through Interruptible Large Boiler Gas Sales Service for IGD-1 customers:

    • Interruptible Large Boiler Gas Sales Service (IS-2 [23 kB PDF]) – MGE provides company-owned natural gas supply on a lower-cost interruptible basis. MGE does not contract for firm interstate pipeline capacity or balancing service to guarantee delivery of supply for IS-2 service, so customers are required to stop using gas when requested to do so. As a result, IS-2 customers’ natural gas service charge is lower than the monthly IS-1 natural gas service charge. Service must be nominated daily, however, and is subject to pipeline over- and under-run charges if your use differs from your nomination. You must be able to interrupt all of the service taken under IS-2. A contract is required for IS-2 service and special equipment will need to be installed at your gas meter site.
  2. Natural gas supply from a third-party supplier: You purchase gas from a different supplier. You then need an MGE balancing service because the interstate pipelines hold MGE accountable for the difference between what your supplier delivers to MGE for you and what you actually use (daily imbalances). The combination of distribution service with balancing service is often referred to as "utility transportation service."

We offer Daily Balancing Service to IGD-1 customers:

  • Daily Balancing Service (DBS-1 [66 kB PDF]) - MGE balances the deliveries that are made by your third-party natural gas supplier with your actual natural gas use daily. A contract is required to for DBS-1 service and special equipment will need to be installed at your gas meter site.
