Commercial Process Improvement

Effective June 1, 2016

As of June 1, 2016, NW Natural will begin providing 2-psig gas delivery pressure as the standard delivery pressure for all services on commercial properties going forward.


NW Natural values your business and we continually seek to serve you in a manner that minimizes disruption and allows for efficient cost management. On your commercial projects that are currently underway, NW Natural’s Construction Field Services (CFS) will offer intermediary regulators to accommodate this change to 2-psig delivery pressure at no cost to you. After December 1, 2016, NW Natural will no longer provide intermediary regulators free of charge.

This change to 2-psig delivery has many advantages for our commercial customers:

Saves Money and Space

  • Pipe size is smaller yet supplies a greater volume
  • Reduced piping material costs
  • Meter assembly requires less space and area, reducing the assembly footprint and allowing for standard multi-meter designs

Provides Added Versatility and Flexibility

  • Pressure control with use of a 2-psig regulator can be adjusted from 7” to 14”wc, depending on the needs of the particular appliances
  • New generation headers with a volume of up to 14.6 therms per drop covers most commercial customers’ needs in a tighter footprint
  • New generation regulators and meter assemblies easily adjust to load variances as they occur and increase over time
  • Built in by-pass ability both for the whole header and individual meters for load sensitive customers

Provides Standardization

  • Commercially each header drop is a minimum of 1” transitioning from a 250 meter rated for 6.3 therms up to a 630 meter rated for 14.6 therms seamlessly without assembly rebuilding

As part of this change to our standard 2-psig delivery to commercial properties, NW Natural will also be updating our Commercial Application for Service.
