RIIO ED-2 DNO Common Network Asset Indices Methodology Version 2.0

The GB Distribution Network Operators (DNOs) are seeking the views of Stakeholders as to the proposed incremental changes to the Common Network Asset Indices Methodology (CNAIM).

This is from the current version (v1.1), as directed for implementation by Ofgem in May 2017, and proposed revised version (v2.0) that modifies CNAIM so that it is suitable for RIIO-ED2 regulatory processes.

In preparation for the RIIO-ED2 period, the Distribution Network Operators (DNOs) have been asked by Ofgem under the SRRWG Committee to review and revise the current Version of CNAIM v1.1 to make it fit for purpose for the RIIO-ED2 period to operate under the NARMs Incentive regime. The changes being proposed will align the CNAIM with the Ofgem requirements for use with the NARMs (Network Asset Resilience Metric) framework as proposed within the SSMC. The DNOs will propose to Ofgem that CNAIM v2.0 will be used to create the required NARMs return for RIIO-ED2 and beyond for reporting against the NARMs requirements in the RIIO-ED2 period (1 April 2023 to 31 March 2028). This is to ensure that the same version of CNAIM is used consistently throughout the RIIO-ED2 process. It is this version of CNAIM and its applicability to RIIO-ED2 processes that is the subject of this consultation.

Responses will be used to support the DNOs submission of the revised version to Ofgem to meet their requirements outlined in Ofgem’s Sector Specific Methodology Consultation (SSMC) published in July 2020.

The consultation will run over the course of September. Please email responses to the ENA Regulation team at [email protected] by 5pm Tuesday 29th September 2020.
