Introduction – How Gas Is Delivered

  • Extracted from wells and moved from collection point into gathering system for sale into the wholesale market
    • Includes processing facility where natural gas is purified and useful by-products such as propane and butane are removed
  • Moved into transmission system using compressors
    • counteracts friction that is created when gas is moved through steel pipe
  • Transported by midstream companies to utility’s delivery point (“city gate”) or to upstream storage
    • Pressure reduced
    • Odorant added
  • Moved into utility’s distribution pipeline and delivered through individual service lines to customer
    • pressure further reduced for delivery
