Superconducting Power Cable Demo :Super Cable 2000 - Phase 1(ST6481-1)

IGC Superpower, Inc.


High-temperature superconducting (HTS) power cables have three to five times the capacity of conventional power cables of the same size, use no cooling oil, and have lower transmission and distribution (T&D) losses. These benefits are significant to dense urban areas such as New York City. Bismuth-based, HTS cables have been demonstrated, but not on a live utility grid, and the viability of yttrium-based superconductors has not been tested.

Project Description

SuperPower proposes to develop high-capacity HTS cables that can be drawn through existing ducts and pipes to increase power transmission levels without trenching, tunneling, and acquiring new rights-of-way. A 10-meter prototype cable will be fabricated, and the ability to splice the cable will be demonstrated. In Phase 2, SuperPower will demonstrate the commercial scale viability of HTS power cables in a live utility grid.


The US DOE estimates that 7% of all electricity is lost in T&D. HTS power cables can cut T&D losses by half. This reduction translates into environmental emissions reductions. The HTS technology will increase capacity by a factor of three to five, compared to a conventional copper-based cable of the same size. A new product line for SuperPower will provide new employment opportunities.

Project Results

Specifications for a HTS cable were created; the prototype cable was not manufactured. It was determined that a cable manufacturer would be needed to support Phase 2 demonstration. Project is complete.
