Planning and rationale

Procedure rationaleCompetition is absent for technical reasons and there are no reasonable alternatives (Procurement Act 2023, Schedule 5, paragraph 6): Arc Suppression Coil (ASC) earthed systems are prevalent on the 33kV and 11kV distribution networks in National Grid Electricity Distribution's (NGED) South West licence area. They were developed early in the 20th century due to the difficulty in achieving low enough earth resistance to operate the incumbent protection systems for high-impedance earth faults. A drawback of ASC systems is that they cannot identify the earth fault location or the specific faulty feeder. Consequently, network control engineers typically must carry out strategic network switching to isolate the faulted feeder, often disconnecting customers on healthy feeders in the process. A joint Network Innovation Allowance (NIA) project 'Arc Aid' was created between UK Power Networks (UKPN) and NGED and successfully developed and trialled a novel advanced grid sensor, the MetrySense 5000, developed by Megger to solve this issue and integrate the results into the NGED Network Management System. Building on the success of the NIA project, this contract seeks to deploy and test this solution at scale.
