Composite Technology Signs Turbine Deal for Minnesota

Willmar Municipal Utilities Buys DeWind D8.2 Turbines

IRVINE, CA–(EMWNews – August 21, 2008) – Composite Technology Corporation (CTC) (OTCBB: CPTC) is pleased to announce that its DeWind subsidiary has signed an

agreement for the sale of two D8.2 two megawatt wind turbines to Willmar

Municipal Utilities (WMU) in Willmar Minnesota. The DeWind D8.2

synchronous power turbine was chosen by the utility after a lengthy

evaluation process and a series of city approvals. The contract is valued

in excess of $6 million with scheduled delivery of the turbines set for May

2009. DeWind will provide nacelles, blade sets and towers.

The State of Minnesota is one of the leading proponents of wind power in

the United States and possesses some of the best wind resources for the

efficient generation of clean wind power. Per the American Wind Energy

Association (AWEA), Minnesota trails only Texas and California in the

amount of installed wind generation, with over 1299 megawatts of installed

capacity as of the end of 2007.

“We are very pleased to place additional turbines in Minnesota and we are

very happy to serve the needs of the Willmar Municipal Utilities. This

order can serve as a model for other municipal and regional utilities to

take advantage of the abundant wind resources of Minnesota and the unique

features of the D 8.2 turbine,” commented Marv Sepe, President of DeWind

and Chief Operating Officer of CTC.

“This contract to provide DeWind turbines will provide clean, renewable

energy to the citizens of Willmar. It is another example of WMU

proactively investing in green generation that will help stabilize costs

and reduce our environmental impact in the future,” stated Bruce Gomm,

General Manager of Willmar Municipal Utilities.

About CTC:

Composite Technology Corporation, based in Irvine, California, USA,

develops, manufactures and sells innovative high performance electrical

transmission and renewable energy generation wind turbines 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 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.

    

--  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.
