Today, the 31st March 2026, the CRU has published a Decision on Interim RNG Distribution Tariffs and Call for Comments on an Enduring RNG Distribution Tariff Framework.
This paper sets out the CRU’s decisions to apply GNI’s proposed interim tariff to all new RNG entry points and to replace legacy arrangements by applying this same tariff to existing biomethane facilities. It also invites stakeholder views on considerations and guiding principles for developing an enduring RNG distribution tariff methodology.
The interim tariff ensures that biomethane injected at distribution level is subject to a clear regulated charge, avoids unpriced access, maintains consistent treatment across biomethane producers, and provides a simple and proportionate solution pending finalisation of an enduring methodology. It also provides clarity to a nascent biomethane industry.
The interim tariff will remain in place only until an enduring distribution‑level tariff is developed and approved. GNI shall develop a timeline and initiate analysis and development of an enduring tariff arrangement for implementation by the 2030/31 gas year. During the interim period, the CRU reserves the right to modify the interim tariff or direct GNI to apply an alternative interim tariff if required. The CRU also reserves the right to extend the interim period should an enduring solution not be in place for the 2030/31 tariff setting cycle.
The CRU will consider responses from all stakeholders on the questions posed in the paper as part of its consideration of a longer-term tariff structure. Stakeholders views should be submitted by 5th May 2026.
Q1. Given the exit-only structure of the distribution tariff methodology do stakeholders agree that the CRU should undertake a holistic review of the distribution tariff methodology as part of developing an enduring RNG entry tariff for the system?
Q2. Are there additional factors or considerations that should inform such a review such as interactions with the transmission tariff methodology?
Q3. Do stakeholders agree with the key principles identified by CRU and are there additional principles or considerations that should also inform the enduring approach? Please provide rationale for your answer.
Q4. Which of the design principles (outlined in Section 3 ) should carry the greatest weight in the enduring methodology and why?
Q5. Should the enduring methodology remain based on a Notional Entry Point or should it evolve to include locational cost signals (either fully locational or zonal) as biomethane penetration increases?
