Composite Technology's DeWind Announces Comissioning of First D8.2 Turbine in U.S.

Composite Technology Corporation (CTC) (OTCBB: CPTC) announced today that its subsidiary DeWind has completed the commissioning of the 2 megawatt D8.2 turbine erected at its Sweetwater, Texas, demonstration site. All mechanical commissioning is complete and the turbine is synchronized with the local power grid. Power is being delivered to the grid for test purposes as part of the optimization process for the turbine which will occur over the next few weeks. Once complete, power curve certification will take place.

Benton Wilcoxon, CEO of CTC, stated, "We are very happy to see our first 60Hz D8.2 has completed commissioning and is delivering power, which represents a major milestone for DeWind. Our customers in 60 Hz markets have been waiting to see an installed D8.2 produce power and synchronize with a 60Hz grid. We have accomplished both goals and have successfully demonstrated the transition from 50Hz to a 60Hz turbine. I am very proud of the hard work our team put forth to position our turbine for the North American market."

DeWind already operates a test site in Cuxhaven, Germany, for the demonstration of 50Hz versions of the D8.2 turbine. The Cuxhaven site has successfully been in operation for over one year with excellent results. The D8.2 turbine incorporates the Voith WinDrive® a hydrodynamic torque converter that allows constant output speed to the generator and synchronous power generation. The U.S. turbine will produce power for the Texas State Technical College, and in an agreement with the college the turbine will become a platform for expanding Wind Technician training programs. The demonstration site is located on land owned by the City of Sweetwater, Texas.

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:

--  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 50Hz and 60Hz; 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 with a synchronous AC generator connected
    directly to the grid at high voltage without the use of power conversion
    electronics. The first 60Hz D8.2 is now installed at a site in Sweetwater,
    Texas, where it will be initially be used for demonstration to North
    American customers. DeWind D8.2 turbines are now assembled at TECO
    Westinghouse Motor Company in Texas for our North and South American
    customers.

--  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 rod is
    delivered to qualified conductor manufacturers worldwide for local ACCC
    conductor production and resale into local markets.
