Composite Technology Announces Production Expansion

CTC Cable Expands Composite Core Production Capacity

Composite Technology Corporation (CTC) (OTCBB: CPTC) is pleased to announce its subsidiary, CTC Cable Corporation, has expanded its composite ACCC* core production capacity to meet increasing demand for ACCC conductors. The Irvine, California, facility has completed an expansion of its core manufacturing area with the addition of over 9,200 square feet of processing space.

CTC Cable is now placing the pultrusion production lines in the area, which upon full population of the floor will expand the production capacity of the facility for ACCC core by over 250%, from its current capacity of 5,200 kilometers per year to over 18,000 kilometers per year. CTC Cable manufactures its own custom pultrusion machines in a separate area of the Irvine facility and plans to place 10 machines in the new production area during the next 3 months.

"Over the last year it became increasingly evident we needed to add capacity. This expansion will be a great benefit to CTC Cable and our customers, since we will be able to shorten production times and take advantage of market opportunities," stated Marv Sepe, COO of CTC and President of CTC Cable.

About CTC:

Composite Technology Corporation, based in Irvine, California, USA, develops, manufactures and sells innovative high performance electrical transmission and renewable energy generation products through its subsidiaries:

--  CTC Cable Corporation produces composite rod for use in its patented
    ACCC* (Aluminum Conductor Composite Core) conductors, which are "high
    efficiency conductors" for use in electrical transmission grid systems.
    ACCC conductors demonstrate less electricity line losses when compared with
    conventional conductors and when deployed in place of conventional
    conductors on existing systems, the higher efficiency of ACCC conductors
    enables power generators to reduce the amount of power they must generate
    while still delivering the same power to the customers.  They have also
    demonstrated significant savings in upgrade capital costs and operating
    expenses when substituted in grid systems for other conductors. ACCC
    conductors enable grid operators to reduce blackouts and brownouts,
    providing a 'reserve electrical capacity' by operating at higher
    temperatures without significant thermal sag of the lines. ACCC conductors
    are an innovative economical solution for reconductoring power lines,
    constructing new lines and crossing large spans. ACCC composite core is
    delivered to qualified conductor manufacturers worldwide for local ACCC
    conductor production and resale into local markets.

--  DeWind Inc. designs, produces, and sells the DeWind series of wind
    energy turbines, including the new 2 megawatt (MW) D8.2 model available in
    both 60Hz and 50Hz; the 2MW D8 model in 50Hz; and the 1.25MW D6 model in
    50Hz. The new D8.2 has been operating since early 2007 at Cuxhaven,
    Germany, and utilizes the advanced WinDrive® hydrodynamic torque
    converter developed by Voith AG in combination with a synchronous AC
    generator with high voltage output that is connected directly to the grid
    without the use of power conversion electronics. The first 60Hz D8.2 is now
    operating at Sweetwater, Texas, where it will initially be used for
    demonstration to North American customers. DeWind D8.2 turbines are now
    being assembled at TECO Westinghouse Motor Co., in Texas for our North and
    South American customers.
