Producer information

Learn more about our green gas producers

This page contains information on the green gas producers who are members of the Green Gas Certification Scheme and for whom we issue Renewable Gas Guarantees of Origin (RGGOs).

In the table below you will see next to each producer their plant code, which appears in the unique identifiers that represent the RGGOs they generate.

Information is also provided on the fuel classifications of the feedstocks each producer is currently able to use under the Fuel and Measurement Sampling Questionnaire (FMSQ) they have agreed with Ofgem. 

Producers may not always use all of the feedstocks agreed within their FMSQ, for example they are able to use feedstocks that are wastes and products but they are currently only using waste feedstocks. Further details may be available directly from producers.

From time to time producers may agree changes to their FMSQ with Ofgem. For information about any historic changes to the fuel classifications of the feedstocks that a plant has made, see the map below.
