DOE announces $117M program to speed demonstration of high temperature superconductor power products

September 26, 2001 — The U.S. Department of Energy (DOE) announced on 24 September 2001 the next round of projects it has selected to fund under the auspices of its superconductivity partnership initiative (SPI).

The DOE selected seven projects from a large list of proposals for the demonstration of high temperature superconducting (HTS) power applications. Power applications to be demonstrated under the SPI include electrical generators, power cables, transformers and magnetic separators for mineral and chemical processing.

“This work will help provide solutions to power quality and electric reliability problems, bringing the benefits of superconductivity more quickly to the U.S. electrical industry and the American people,” said Energy Secretary Abraham in the DOE announcement.

The total investment in the seven projects over the next three to four years is expected to be $117 million, with approximately $57 million coming from the DOE and the balance from the industry participants. This investment is intended to advance the commercialization of HTS technology in electric power applications across the power infrastructure, including production, delivery and use of power.

“There is growing market momentum for HTS technology in the power infrastructure,” said Greg Yurek, chief executive officer of American Superconductor. “Utilities are turning to HTS technology as part of their investment strategy for meeting their future power transmission requirements. The SPI program is important because it hastens the development and commercialization of HTS technology in key utility applications.”

HTS Power Cable for Long Island Grid

A team led by Pirelli Power Cables & Systems was selected by the DOE-SPI to demonstrate an HTS cable in the power grid of Long Island Power Authority (LIPA) on Long Island, New York.

American Superconductor is the HTS wire supplier and a partner with Pirelli on this project. The other partners are LIPA, the Electric Power Research Institute (EPRI) and Air Liquide. The cable system will be based on a co-axial (cold dielectric) design and will deliver 77 MW of power over approximately one-half mile in LIPA’s power transmission grid near East Shoreham on Long Island.

The Long Island HTS power cable project is a Phase III, pre-commercial SPI program and builds on previous HTS power cable projects including one under way in Detroit with Detroit Edison. The Detroit demonstration consists of three, single-core (warm dielectric) cables each approximately 400 feet in length, which are located in a substation in downtown Detroit. The Long Island cable project, involving three HTS cables each about one-half mile long, will be the longest HTS cable installation to date. The cables will be installed in a section of the LIPA transmission grid between two substations. This represents a key step towards the commercialization of HTS underground power cables. The project funding totals approximately $18 million with half of that coming from the DOE.

In addition to single-core (warm dielectric) HTS cables, Pirelli has already manufactured 150-foot-long co-axial (cold dielectric) HTS cables that are expected to be operated at utility test facilities in France next year. The Long Island pre-commercial cable will build on this experience.

Detroit Progress Report

Pirelli installed three HTS cables in the Frisbie Substation in Detroit this past summer, matching the power carried by nine copper cables that had been in the same right of way. This HTS cable system includes a splice constructed in a manhole, a key component in the demonstration of practical applications of HTS cables. The HTS cable system is expected to be serving 14,000 Detroit Edison customers this fall.

AMSC First Generation HTS Wire

Five of the seven winning projects, including the Long Island cable, involve the use of first generation HTS wire. American Superconductor, which produces the highest performance, lowest cost HTS wire in the world, expects it will be providing HTS wire to several of the projects. Two of the projects intend to use other forms of HTS material, including solid forms for bearings and melt-processed wire for an MRI application. Final contracts between the DOE and the prime contractors still need to be negotiated after which suppliers of the HTS wire will be chosen. It is expected that contracts will be underway in the first quarter of calendar 2002.
