Composite Technology Completes Transmission Upgrade in Spain

Composite Technology Corporation (CTC) (OTCBB: CPTC) is pleased to announce the completion of an ACCC installation in Spain that dramatically boosted the capacity of an existing transmission line carrying power from a wind farm to the grid. The installation is an excellent example of how the attributes of ACCC conductor produced by Composite Technology's subsidiary, CTC Cable Corporation, meets the energy efficiency goals of the wind power generation industry.

The ACCC conductor was installed in Northwest Spain approximately 35 miles from the city of Santiago de Compostela. The contract was executed by NEO Energia of Sevilla, Spain. The 69KV line was reconductored with CTC Cable's Amsterdam size conductor to double the capacity of the transmission line carrying power from the 80 turbine wind farm to the grid. The wind farm will expand to 160 turbines and more transmission capacity was needed. The engineering firm chose ACCC Conductor to replace the existing conductor because of the increased capacity, reduced sag characteristics and minimal engineering that was required to complete the project. No tower upgrades were required although a number of towers were replaced as part of the routine maintenance of the line in the mountainous terrain.

"ACCC Conductor has been used in dozens of installations around the world. The Spanish installation is a good example of doubling the transmission capacity of a line with minimum cost and impact. A simple reconductoring with our highly engineered product was the cornerstone of the project," 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 products and renewable energy generation wind turbines 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. ACCC conductors
    have also demonstrated significant savings in upgrade capital costs and
    operating expenses when substituted in grid systems. They also 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 provide economical
    solution for reconductoring power lines, constructing new lines and
    crossing large spans. ACCC conductors are produced by licensed qualified
    conductor manufacturers worldwide which produce sell 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. D8.2 and D8 turbines are now being
    assembled at TECO Westinghouse Motor Co.
