Clipper Windpower, Inc. is a rapidly growing wind energy technology company which manufactures the 2.5 MW Liberty turbine and actively develops wind power generating projects in the Americas and Europe.
The patented technology of the Liberty turbine developed by Clipper substantially increases the efficiency of wind-generated electricity, providing a formidable increase in the potential geographic areas for turbine deployment. In recognition of the merits of this advanced technology and for Clipper's highly experienced management and engineering team, the company was awarded grants from the U.S. Department of Energy ("DOE") and the California Energy Commission ("CEC") for development of the turbine. The Liberty turbine has certification (Germanischer Lloyd) to international standards.
The Company's wind power development activity includes the sale of the 44 MW Flying Cloud project under a joint development agreement with Pacific Corp. in 2003, and the 160 MW Intrepid project acquired by MidAmerican Energy in 2004. In 2005, Clipper completed essential project development requirements for its 100 MW Criterion Facility and its 150 MW Endeavor Facilities and will be using 40 and 60 Liberty turbines, respectively, for installation.
Clipper Windpower Inc. is a wholly owned subsidiary of Clipper Windpower Plc, a public limited company that is organized under the laws of the United Kingdom and Wales and domesticated in the United States under the laws of the State of Delaware. The shares of Clipper Windpower Plc are traded on the Alternative Investment Market of the London Stock Exchange under the symbol CWP.

2.5 MW Liberty Wind Turbine for IEC class I, II & III wind conditions
Advanced generator control technology enables wide range variable rotor speed, improving turbine aerodynamic efficiency by adjusting to ever-changing wind velocities, briefly storing and releasing energy from wind gusts while also reducing torque spikes. Net benefit: More production and extended life.
Capabilities
We cover the full range of activities needed for successful wind project development and plant operation. This means combining appropriate wind turbine technology, with efficient plant design and construction methods, and also providing management for all technical and business factors as outlined below.
- Wind resource acquisition and management
Clipper acquires and maintains a substantial 6500 MW portfolio of wind resource rights for the development of projects utilizing Clipper wind turbines. This includes, among other things, wind flow analyses, environmental assessments, regulatory and permitting approvals, power contracts, transmission and interconnection agreements.
- Project design and engineering
Clipper designs the turbine layout, power collection, transmission interconnection and substations, civil work and project logistics. Project design is based on advanced methodologies in analyzing the siting of turbines to maximize energy capture from the wind.
- Project finance
With over $1 billion of successful financing completions, new projects benefit from cutting edge financing options and structures. Developing the financial structure, negotiating terms and documentation, and interfacing with financial institutions is a core competency and part of Clipper's process for making sure that every aspect of the project is optimized.
- Construction
Clipper can provide turn-key construction or construction supervision, and arranges all subcontractor agreements. Our management team's expertise includes over 3,000 direct and/or oversight wind turbine installations at sites ranging from desert floors to mountain ridgelines. These installations have included high voltage transmission lines and substations, wind turbines and all related wind power facility infrastructure.
- Operation and Maintenance
Once a windpower facility is commissioned, Clipper provides ongoing operation and maintenance services. This responsibility assures maximum production of electricity while maintaining an appropriate balance between short and long-term operating costs. High plant performance and availability require constant surveillance, and methodical preventive and scheduled maintenance services for high turbine availability and reliable operation.
Current Clipper Projects
Clipper's net ownership of its wind resource portfolio currently totals over 6,500 MW, with additional prospects under early stage development. Our projects can be found throughout the US and Latin America including Iowa, Maryland, Texas and Wyoming. Following is a sampling of our most requested project developments.
Criterion – Maryland
Endeavor I – Iowa
Flying Cloud – Iowa
Intrepid – Iowa
Medicine Bow, Wyoming – First Commercial Liberty® 2.5 MW Wind Turbine
Silver Star I – Texas
Victory I – Iowa

How We Serve You
Electric Utilities, Electric Cooperatives, and Municipalities
Higher shareholder and member values and bond ratings are realized by electric utilities with attractively priced long-term energy supply arrangements. Power from wind plants in a utility's energy mix helps achieve this, while also providing the opportunity for premium pricing to utility customers preferring a "green power" option. Clipper's projects are based on power contracts tailored to a utility's requirements. Wind energy also provides a hedge against fuel price uncertainty by offering stable long-term power contracts.
Corporate Power Consumers
Clipper has a wide range of options to meet your long term electricity needs and goals, from tailored power contracts to ownership of generating capacity. Companies are increasingly seeking to diversify their energy sources, particularly when they can lock-in attractive long-term windpower pricing while also helping the environment by reducing reliance on fossil fuels. In addition to windpower's economic benefits, drawing on wind energy reinforces a corporate image of environmental and social responsibility.
Landowners
Farmers and ranchers in windy regions gain significant financial benefit from the development of wind energy on their land. Evaluating a site's potential (at no cost to the landowner) may be accomplished by requesting Clipper make a preliminary assessment of the land, the wind resource, transmission, and other key factors. If the site is suitable, the landowner receives long-term royalties once a project starts operating.
