The SoCalGas® Compression Services Tariff, GO-CMPR(PDF) is a non-residential, optional tariff service for customers that allows SoCalGas to plan, design, procure, construct, own, operate and maintain compression equipment on customer premises to meet pressure requirements as requested by the customer and agreed to by SoCalGas. Examples of customer end-use applications that can be served by the Compression Services Tariff include compressed natural gas (CNG) vehicle refueling stations, combined heat and power (CHP) facilities and peaking power plants.

Customers interested in the Compression Services Tariff should be aware of the following:

  • The Compression Services Tariff is a fully elective, optional, non-discriminatory tariff service that is neither tied to any other tariff or non-tariff services the customer may receive from SoCalGas, nor will it change the manner in which these services are delivered. As an example, requests for natural gas service are processed on a “first-come, first-served” basis for all customers, including customers who elect to take the Compression Services Tariff and customers who do not.
  • Any agreement to provide service under the Compression Services Tariff is at SoCalGas’ discretion and will depend on non-discriminatory factors such as safety, system capacity, SoCalGas resource availability, technical feasibility and acceptability of commercial terms.
  • SoCalGas will not engage in any activities downstream of the point of service delivery which is typically the outlet of the compression facilities. In particular, any retailing or fuel dispensing activities are the responsibility of the tariff customer.
