National Grid Gas purchases Operating Margins (OM) on an annual basis in line with both the requirements of section K of the UNC and obligations described in the National Grid Gas Safety Case (the Safety Case).  The Safety Case places an obligation on National Grid Gas to maintain OM at levels and locations determined throughout the year.

For information on becoming an OM provider please contact Chris Cortopassi on +44 (0)1926 656859 or via e-mail Christopher.Cortopassi@uk.ngrid.com.

Operating Margins Contestability Project

At its last Transmission Price Control Review, National Grid Gas accepted NTS Special Licence Condition C25, which requires it to “…use reasonable endeavours to promote competition in the provision of Operating Margins (“OM”) services…”. A significant amount of work has been completed in this regard, including successful engagement with the industry via three consultations, workshops, a UNC modification proposal and a range of bilateral meetings, all with the aim of ensuring, as far as possible, that barriers to participation are removed and that interested parties were able to participate in the development of proposals, thereby giving them the best chance of success.

To gain a better understanding of the work undertaken to date with regards to Gas Operating Margins please refer to Gas SO Incentives Consultation 3.
