Winter Reliability Industry Assessment
Pennsylvania Public Utility Commission
Annual Winter Reliability Assessment
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
