Alternative Gas Supplier Licensing

Public Act 634 of 2002 requires Alternative Gas Suppliers (AGS) to be licensed before doing business in Michigan. On March 12, 2003, the Commission established licensing procedures for suppliers participating in Commission-approved natural gas customer choice programs (see order). The licensing procedures apply to any person selling natural gas at unregulated retail rates in Michigan and participating in a Commission approved gas choice program.

In Case No. U-15929 the Commission initiated a contested case proceeding to investigate whether any clarifications, revisions, or additions should be made to current utility gas customer choice tariffs. The October 13, 2009 Order in that case adopted changes to the approved gas customer choice tariffs for the participating utilities.

     Consumers Energy Company (permanent customer choice program that began 4/1/01)
