Sands China Resorts in Macau to Save Energy with Power Efficiency’s Motor Efficiency Controllers

The Venetian® Macao, Sands Macao and Four Seasons Hotel Macao to Install Motor Efficiency Controllers on 96 Escalators

March 23, 2010– Las Vegas, NV – Power Efficiency Corporation (OTCBB: PEFF), a clean tech company focused on energy efficiency technologies for electric motors, has received an order for the purchase and installation of its 3-phase motor efficiency controllers, from three resort properties owned by Sands China Ltd., a majority owned subsidiary of global resort developer Las Vegas Sands Corp. The three properties - The Venetian Macao, Sands Macao and The Four Seasons Hotel Macao – are in Macau, a special administrative region of China.  A total of 96 motor efficiency controllers are to be installed at the properties.

Power Efficiency’s 3-phase motor efficiency controllers feature E-Save Technology®, a patented and patent-pending technology platform that typically saves energy usage by up to 35% in appropriate applications.  In addition to escalators, Power Efficiency’s 3-phase motor efficiency controllers can be used in a wide variety of industrial applications, such as conveyors, mixers, grinders, crushers, granulators and shredders.  Power Efficiency has also developed a 1-phase motor efficiency controller for use in household appliances such as washers, dryers and refrigerators.

Las Vegas Sands is the leading global developer of integrated resorts, featuring premium accommodations, world-class gaming and entertainment, retail, convention and exhibition facilities, celebrity chef restaurants, and many other amenities. The Las Vegas Sands is the sole or majority owner of seven resort and convention properties worldwide, including The Venetian and The Palazzo, both Five-Diamond luxury resorts on the Las Vegas Strip. Within the next few months the Las Vegas Sands plans to open an additional property, the Marina Bay Sands in Singapore. Sands China Ltd. will open three additional properties on the Cotai Strip in Macau, the Shangri-La, Traders, and Sheraton.

Steve Strasser, Chairman and CEO of Power Efficiency Corporation, commented, “Sands China’s resorts in Macau are highly regarded global travel destinations. The installation of Power Efficiency’s Motor Efficiency Controllers at these high-profile locations indicates growing acceptance of our E-Save Technology in the vertical transportation market. Marquee projects like this help accelerate customer demand and build sales momentum for Power Efficiency’s products.”

Strasser continued, “This is our first major project in Asia, which is our largest vertical transportation market. China, for instance, represents close to half of global escalator sales. In addition, China’s vertical transportation and industrial equipment buyers are sharpening their focus on energy savings, which we believe will increase demand for our motor efficiency controllers. This project will greatly increase awareness of our products in China and other parts of Asia.”
