Albany, New York grid to receive HTS power cable

Design intended to demonstrate evolution of key technology in standard urban right-of-way

LATHAM, N.Y., Aug. 14, 2001 – Intermagnetics General Corporation today announced that its IGC-SuperPower subsidiary will lead a $20 million project to install an underground, high-temperature superconducting (HTS) power cable in Albany, N.Y. The cable, to be installed in Niagara Mohawk Power Corporation’s power grid and to incorporate components manufactured by Nexans, is designed to demonstrate enhanced capacity, reliability and power quality of HTS cables.

Governor George E. Pataki announced separately that The New York State Energy Research and Development Authority (NYSERDA) will award IGC-SuperPower $6 million for the project. The company will assume responsibility for the majority of the remaining cost during the next three years.

“High-temperature superconducting power cables hold the promise of increasing the state’s electricity supply without increasing power plant emissions or expanding the transmission network,” said NYSERDA President William M. Flynn. “A successful demonstration with IGC-SuperPower will mean tremendous economic development opportunities for this upstate company and, ultimately, even greater reliability and service in New York City and other urban areas where these cables have the greatest future potential.”

“The one-quarter-mile cable, believed to be four times the length of any previously installed HTS cable, will be designed to provide more power and operate at significantly lower loss levels than other HTS installations,” said Glenn H. Epstein, president and chief executive officer of Intermagnetics.

The project is expected to be completed in about three years.

James B. Howe, regional manager for Niagara Mohawk, added: “This technology holds exciting potential for increasing the capacity of our infrastructure and lowering energy delivery costs. In the long-term, successful completion of this Albany-based project could have an impact not only on the local economy, but also on the national – and even international – power transmission cable industry.”

IGC-SuperPower named Nexans as a designer and supplier of certain components for this project.

Jean-Maxime Saugrain, superconductor activity manager for Nexans, commented: “HTS has the potential to revolutionize the distribution of energy and Nexans is committed to participation in the development of this exciting technology. We are delighted to have this opportunity to work with Intermagnetics – an internationally renowned leader in the commercialization of products based on applied superconductivity.”

Project To Include Testing Of 2nd- Generation HTS Technology

Although first-generation HTS material will be used for this particular project, IGC-SuperPower intends to separately build a laboratory scale section of HTS cable using second-generation conductor in order to test its properties. Second-generation materials employ less labor intensive methods and less expensive materials. SuperPower is working to develop a commercial- level manufacturing process for second-generation HTS conductor, which is believed to be necessary to achieve the cost-performance levels required for commercialization of HTS cables and devices.

Niagara Mohawk Power Corporation (http://www.nimo.com) is a wholly owned subsidiary of Niagara Mohawk Holdings Inc., an investor-owned energy services company that provides electricity to more than 1.5 million customers across 24,000 square miles of Upstate New York.

Nexans is a participant in the cable industry. The group brings a range of advanced copper and optical fiber cable solutions to the infrastructure, industry and building markets. Nexans cables and systems can be found in telecommunications and energy networks, aeronautics, aerospace, automobile, building, petrochemical and medical applications, etc. More information on http://www.nexans.com.
