LIPA and American Superconductor Bring the Largest Superconducting Transmission Cable to Long Island

Nexans takes part of this major project that will result in the world’s first transmission voltage superconducting power cable installation in a live grid

Superconductor LIPAHauppauge, NY-August 2, 2006 -As in the midst of a scorching heat wave, and part of its commitment to ensure economical, safe and reliable electricity to its customers, the Long Island Power Authority (LIPA) held a Groundbreaking Ceremony today in Holbrook to announce the construction phase of the world’s largest and highest-voltage superconductor electric transmission cable system. The 138,000 volt (138kV) cable system, nearly one-half mile in length, will be the world’s first superconductor cable installed in a live grid at transmission voltages and will carry more power than all previous high temperature superconductor (HTS) cable demonstrations combined.

The project is being undertaken by a government-industry partnership. Other partners participating in the ceremony included the United States Department of Energy, American Superconductor Corporation (NASDAQ: AMSC), Nexans and Air Liquide. 
The purpose of this project is to demonstrate the operation of a high voltage superconducting cable within an electric utility transmission system.  The cable will be installed by early 2007 in LIPA’s Holbrook transmission right of way running north/south for about 2,000 feet.  Both ends will be connected to LIPA’s existing transmission system.

"As the worldwide leader in the cable industry, Nexans has been actively engaged in research into superconductors over the past few years. From our Superconductivity competence center's laboratories based in Germany to Long Island's grounds, we have made huge progress, so today, we are delighted to be part of this major project that will result in the world’s first transmission voltage superconducting power cable installation in a live grid. At a time when world energy demand keeps increasing, growth opportunities for superconductor cables are becoming bigger. Nexans is taking up this industrial and market challenge to provide power transmission solutions of very high ratings utilizing high temperature superconductors," said Gordon Thursfield, President, Nexans North America.
