Network Asset Risk Methodology document consultation
National Grid Electricity Transmission is obliged to review the Network Asset Risk Methodology (NARM) and its associated documentation in accordance with NGET's License condition SpC 9.2. These documents may be modified from time to time, to better facilitate the NARM objectives. The NARM consists of a Common Methodology, adopted by all Transmission Licensees in GB, plus a network specific annex.
The NGET Network Asset Risk Annex (NARA) covers the detail required to implement the Common Methodology. Technical requirements and functionality of different networks mean individual implementations can differ.
The Electricity Transmission Owners have been working with Ofgem to address areas for improvement. A development road map was established in 2022, providing direction to both licensees and Ofgem and allowing for appropriate resource planning. The road map grouped the proposed developments into three groups of activity as follows:
- Category 1. Short term methodology modifications, focus on facilitating transparency and completeness of the Methodology documents.
- Category 2. Short to medium term methodology modifications, focus on improving alignment within and across sectors.
- Category 3. Medium to long term methodology modifications, focus on expanding the methodology to incorporate new assets and refining the calibration values to ensure comparability analysis of Monetised Risk between different networks.
This consultation corresponds to the Category 2 agreed modifications, plus additional material necessary to implement the RIIO-T3 price control.
A brief summary of the proposed changes and questions for consultees are given in the attached Stakeholder Consultation document.
