SCADENT – Superconducting Applications for Dense Energy Transmission

Using High Temperature Superconductor technology to help meet the anticipated increased demand for electricity is being explored.


The SCADENT project is being developed under Ofgem’s SIF (Strategic Innovation Fund), with National Grid Electricity Transmission (NGET) as lead partner. Frazer-Nash is managing the project on NGET’s behalf, and is providing technical and economic expertise along with project partners including cable manufacturers (Nexans, AMSC), Universities (Strathclyde, Manchester) and DNOs (UKPN, WPD, SPEN). 

The use of High Temperature Superconductor (HTS) technology could help meet the anticipated increase in demand for electricity that will result from a shift towards electrification for heat and transport.

HTS cables are capable of delivering 3 to 5 times the power of conventional cables in the same space, or can be used to deliver the same power at a lower voltage. Both options deliver a reduced infrastructure footprint, which is important in space-constrained areas such as city centres, particularly as these are the locations where electricity demand will increase the most as we progress towards Net Zero.

SCADENT aims to develop an understanding of the barriers, opportunities, and benefits of modernising existing electricity infrastructure by replacing conventional cables with HTS cables.

The project completed its ‘Discovery’ phase in May 2022 and is currently in the ‘Alpha’ phase, identifying GB grid locations for the deployment of the technology; producing the technical specifications and costing details for these locations; and developing a suitable test set-up for the HTS solution.    The aim for the ‘Beta’ phase is to build a test HTS cable and iron out any issues prior to HTS technology being deployed live on the GB grid.
