WindStor Wind Turbine Performance Testing Update

FARMINGTON HILLS, MI -- (MARKET WIRE) -- May 9, 2005 -- WindStor Power Co., a wholly owned subsidiary of McKenzie Bay International, Ltd. (OTC BB: MKBY), is pleased to report that after 6 months of testing, its vertical axis wind turbine is providing better than expected operating results. "The WindStor Wind Turbine ("WWT") generated peak power of 104 kW, at a significantly lower wind speed than its 100 kW rated capacity. The WWT is generating more electricity, at lower wind speeds, than originally projected," reported Doris F. Galvin, President of WindStor Power Co.

The WWT, a 100kW vertical axis wind turbine, was installed in October, 2004 at the Université du Québec en Abitibi-Témiscamingue in Rouyn-Noranda, Quebec, Canada, the long term R&D and performance testing site for WindStor Power Co. technology. Planned for commercial introduction in 100 and 200kW configurations later this year, WindStor Power Co. intends to install the award-winning-design turbine as part of the WindStor(SM) wind energy system. WindStor(SM) will be installed in urban and off-grid locations and will generate and sell power directly to the customer. The Université du Québec is scheduled to provide WindStor Power Co. with a final report on the performance of the vertical axis wind turbine prototype by mid-summer 2005.

"Distributed Generation ("DG") utilizing our WWT, a viable renewable energy device, is a new concept for commercial applications," said Ms. Galvin. "We believe in and are committed to DG as an important solution for our prospective customers, the transmission grids and Homeland Security. Coupling DG with renewable energy is a sustainable and timely innovation."

WindStor Power Co. is the owner and operator of WindStor(SM), a wind energy system designed to integrate distributed generation wind power installed on or near a building with grid power. WindStor(SM) will feature WindStor Wind Turbines, a proprietary system integrator and if applicable, a battery. DERMOND, Inc., a subsidiary of WindStor Power Co., is the designer of the WindStor Wind Turbine.
