  • Entry Capacity Release Methodology Statement

  • The Entry Capacity Release Methodology statement (ECR) describes the methodology that National Grid employs to determine the quantity of entry capacity that it will release to comply with its obligations in the Licence and Uniform Network Code. It applies to all entry capacity, i.e. existing system entry capacity and additional "incremental" entry capacity. In particular, it defines under what circumstances National Grid will accept applications for incremental entry capacity from Shippers received through processes described in the Uniform Network Code, and thereby the level of financial commitment required from those Shippers.

    At the top of this page is the current version of the ECR. Below this are documents relating to any review of the ECR and related consultation material that is currently being consulted upon.
