How gas flows from the wellhead to customers

  1. ANR Pipeline and Guardian Pipeline transport natural gas (for both firm and interruptible system sales customers, as well as gas transportation customers) from the wellhead to the WPS distribution system.
  2. ANR Pipeline and Guardian Pipeline meter the total amount of gas flowing to the WPS distribution system.
  3. WPS distributes natural gas from its city gate station to its customers. Any difference between nominated deliveries and actual use must be balanced by WPS each day. The utility is subject to additional charges from the pipeline when contract limits are reached because of high or low use.
  4. The difference between nominated gas deliveries and actual gas usage is reconciled by injecting or withdrawing additional gas from WPS storage fields in Michigan.
