Modification of Special Condition 3.14 Asset Health Re-opener of National Gas Transmission Plc's gas transporter licence

We are proposing a modification to National Gas Transmission Plc's licence, Special Condition 3.14 Asset Health Re-opener, to correct the current drafting which does not accurately reflect the original policy decision set out in RIIO-T2 Final Determinations. This will extend the scope of the Asset Health Re-opener to include interventions related to Valves. It will also extend the true-up mechanism applicable to relevant allowances to cover the entire period from 1 April 2021 to 31 March 2024.
