Shipment of Completed 30-Meter HTS Cable For
Installation Into The Albany HTS Cable Project Announced
Schenectady, NY, 2 May 2007:
SuperPower, Inc.
has announced that the completed 30 meter second-generation high temperature
superconducting (2G HTS) cable has been shipped from the Sumitomo Electric
Industries Osaka Works in Japan and is enroute to Albany, New York. The
cable was fabricated by Sumitomo, SuperPower's partner in the Albany HTS
Cable Project, from nearly ten kilometers of 2G HTS wire that was delivered
by SuperPower to Sumitomo in December 2006, and will be installed into the
cable system at National Grid's North Albany Service Center later this
year. This will be the world's first use of 2G HTS wire in any device and
the first installation on a live grid.
Philip J. Pellegrino, president of SuperPower,
said "The fabrication and delivery of high quality 2G HTS wire to Sumitomo
in December has marked SuperPower's entry into the commercial manufacture of
this superior superconducting wire. We continue to lead the world in the
production of long lengths of high performance wire and look forward to a
successful demonstration of its capabilities during the next few months.
HTS cables, which can carry about five times the electrical current of the
copper cables currently in use on our grid, will offer significant
advantages as our nation addresses the need to improve and upgrade our
electrical transmission network. The expectation that 2G HTS wire will be a
cost-effective replacement for copper by the end of the decade will be an
important factor in determining the adoption rate."
Ryosuke Hata, Managing Executive Officer and
Deputy General Manager of Sumitomo Electric Industries in Osaka, Japan, said
"Sumitomo is pleased to report the successful fabrication and testing of
this new 2G HTS cable, another milestone achievement for the Albany HTS
Cable Project. This demonstration is an important step forward in bringing
the efficiency benefits of HTS technology to energy users around the
world."
In July 2006 the 350 meter underground power
cable, consisting of two sections that are joined in an underground vault,
was energized. Since that time the 34.5 kV system has accumulated nearly
7000 hours of run time with routine maintenance work performed on the
related cooling systems without interruption to cable operations. In
November 2006, the cable successfully withstood a fault current event which
is not uncommon to grid operations, further demonstrating the durability and
reliability of the system.
"Responsibly meeting the energy needs of the
future relies on our actions today. National Grid is proud to be a part of
this project as it continues to demonstrate the promising potential of this
new technology," William Flaherty, vice president for business services for
National Grid's eastern division said.
In addition to providing the 2G HTS wire,
SuperPower is managing the project that began in 2002. Sumitomo is the
cable system designer and manufacturer, and BOC Gases, the US affiliate of
the Linde Group, is responsible for the design, engineering, installation
and monitoring of the cryogenic refrigeration system that keeps the cable
running at 77 Kelvin.
"BOC is proud to observe this important
milestone as we work with our partners to develop solutions to meet the
world's ever-increasing demand for power," said Edward Garcia, vice
president, ventures, BOC.
The $27 million project is being funded by
nearly $14 million from the U. S. Department of Energy, $6 million from the
New York State Energy Research and Development Authority (NYSERDA), with the
remaining cost being shared by the partners.
The project has two distinct phases. Phase
I, which has been completed, consisted of the initial installation of two
cable sections, 320 meters and 30 meters, both fabricated with
first-generation (1G) HTS wire. In Phase II, the 30 meter section will be
removed and replaced with the 30 meter section of 2G HTS cable now enroute
to Albany. The cable will be taken off line during the first week in May,
followed by warm-up to ambient temperature (cable normally operates at -320o
F). The installation of the new 2G HTS cable will begin in July following
the removal of the original 1G cable section. After a series of related
construction activities are completed, the entire system will be cooled down
again, tested and then re-energized in October 2007.
SuperPower, Inc. is a subsidiary of Philips
Holdings USA, the US holding company for Royal Philips Electronics NV,
following Philips' November 2006 acquisition of Intermagnetics General
Corporation. SuperPower was formed in March 2000 by Intermagnetics to
provide a strong focus for the development and commercialization of HTS
technology for the energy technology sector.
