Find out how we can bring high-efficiency technology to your business to help save energy and reduce costs.
The Distributed Energy Resources Services (DERS) Tariff, Schedule GO-DERS is an optional tariff service for customers which allows SoCalGas to plan, design, procure, construct, own, operate and maintain Combined Heat and Power (CHP) as well as Waste Heat to Power (WHP) facilities on customer premises.
Distributed Energy Resources Services (DERS) are provided under this Tariff based upon arrangements mutually satisfactory to the host site and SoCalGas for design, location, construction, and operation of required DERS facilities. Examples of customer end-use applications that can be served by the Distributed Energy Resources Services Tariff include, but are not limited to: electrical loads, hot water, hot air, steam, process heat, chilled water, and chilled air.
Non-utility service providers may offer services that are the same or similar to the Distributed Energy Resources Services Tariff and customers are encouraged to explore these service options. To assist customers in understanding all of their service options, the US Department of Energy has compiled a list of suppliers1 which includes project developers, consultants, equipment manufacturers, installers and others.
Customers interested in the Distributed Energy Resources Services Tariff should be aware of the following:
- The Distributed Energy Resources Services Tariff is a fully-elective, optional, nondiscriminatory tariff service that is neither tied to any other tariff nor 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 a new natural gas meter are processed on a “first-come, first-served” basis for all customers, including customers that elect to take the Distributed Energy Resources Services Tariff and customers that do not.
- Any agreement to provide service under the Distributed Energy Resources Services Tariff is at SoCalGas’ discretion and will depend on non-discriminatory factors such as safety, SoCalGas resource availability, technical feasibility, and acceptability of commercial terms.
- SoCalGas will not engage in any activities upstream from the point of receipt for DERS facility fuel or downstream from the service delivery point for energy outputs. In particular, the establishment of the electrical interconnection is the responsibility of the tariff customer.
- The customer is the sole owner of any energy outputs delivered by the Distributed Energy Resources Services Tariff. The customer is solely responsible for any electricity to be sold or exported back to the grid.

Other limitations that apply to the DERS Tariff include, but are not limited to, the following:
- Combined heat and power systems provided through the DERS Tariff must meet the California Public Utilities Commission’s Self-Generation Incentive Program (SGIP) efficiency and greenhouse gas emission standards.
- SoCalGas will only install combined heat and power facilities that are fueled wholly by natural gas, biogas, or other gaseous fuels such as hydrogen or hythane.
- The nameplate capacity of the installed combined heat and power system will be less than or equal to 20 Megawatts (MW). If SoCalGas installs multiple systems on one customer’s premises, the total nameplate generating capacity built on that premises must be less than or equal to 20 MW.
- The combined heat and power systems installed through the DERS Tariff must meet the requirement that all facilities meet the “fundamental use test” as defined in the federal definition of cogeneration, which requires the energy outputs from the system to be useful.
