Composite Technology Announces Line Installation Project in Scotland

IRVINE, California, June 22, 2011 -

- ACCC® Conductor
Chosen for 132 kV Project in the UK

Composite Technology Corporation (CTC) (OTC Bulletin Board:
CPTCQ) is pleased to announce that Scottish Hydro Electric
Transmission Ltd (SHETL) has selected and successfully installed
ACCC® Oslo conductor for a new line between St. Fergus and
Peterhead in the northeast of Scotland.

The eleven kilometer, three-phase line operates at 132kV and is
strung on a trident wood pole design. Installation of the conductor
began in February 2011 and was successfully completed and the line
energized in May 2011.

SHETL selected the ACCC® 318 mm2Oslo conductor for this line
because of its ability to run at higher temperatures than
conventional conductors, bringing increased capacity to the
line.

Stewart Ramsay, President of CTC Cable Corporation, commented:
“We are very pleased that SHETL selected ACCC® conductor for this
project.  We believe that the superior performance of ACCC®
conductor, including its higher capacity and the lowest line losses
on any conductor available today, will bring real benefits to both
the transmission company and its customers, and will contribute
towards the UK meeting its CO2 emission reduction targets.  We
look forward to working with SHETL on other transmission network
projects in the future.”

SHETL Group Design Manager Landel Johnston said: “This project
is a significant investment in the electricity transmission
infrastructure in Scotland, ensuring a safe and reliable
electricity supply for years to come. We are always looking at
innovative solutions and new developments within the industry
worldwide and are delighted to be the first in the UK to install
the ACCC® conductor on this strategic project in Scotland. It has
been selected for this installation and will form part of an
ongoing assessment as a possible future alternative for our
numerous reconductoring projects if the technology proves cost
effective operating on our network.

“It is SHETL’s responsibility to develop the transmission system
in the North of Scotland, to allow for new demand and generation
access to the transmission network.  This project is another
step in the progress of upgrading the transmission network in the
north of Scotland and has taken some time to plan, involving
extensive work with local landowners.”  

Scottish and Southern Energy:

Scottish Hydro Electric Transmission (SHETL) is responsible for
operating, maintaining and investing in the transmission network in
its area, which serves around 70% of the land mass of Scotland.
 As the licensed transmission company for the area, SSE has to
ensure there is sufficient network capacity for those seeking to
generate electricity from renewable (and other) sources within it.
 

About CTC:

Composite Technology Corporation’s patented ACCC® conductor
technology enables superior performance of high voltage
transmission and distribution electrical grids. ACCC conductors use
CTC’s proven carbon fiber core which is produced by its subsidiary,
CTC Cable Corporation, at its Irvine, California headquarters and
delivered to qualified conductor manufacturers who produce and
distribute ACCC conductors to operators of electrical grids
worldwide. CTC’s conductor technology significantly reduces thermal
line sag and can replace similar diameter and weight traditional
conductors with its higher capacity and more energy efficient ACCC
conductor. It is an ideal conductor for both upgrading existing
power lines as well as building new lines since the technology
allows for the reduction of the number of support structures and/or
a reduction of their height. Since its commercial introduction in
2005, ACCC conductor has been selected for over 10,000 kilometers
(6,214 miles) of projects in all environmental and operating
conditions, including severe heat and ice environments, long span
applications and high capacity corridors for the modern grid. ACCC®
is a registered trademark of CTC Cable Corporation.
