Wind Demonstration Project

Keys Energy Services (KEYS) installed two wind turbines at its Cudjoe Key Electrical Substation on U.S. Highway 1 (MM 23, Oceanside). The Wind Demonstration Project is funded in part by a Clean Energy Grant KEYS was awarded from the State of Florida totaling $770,000. The grant was made possible by the American Recovery and Reinvestment Act and the United States Department of Energy.

Construction of the Wind Demonstration Project cost $46,000 and KEYS worked with Florida Keys-based Sea, Air, Land Technologies (SALT) who furnished and installed the turbines per a competitive bid process. Originally one turbine was going to be installed at KEYS' Stock Island Generation Facility and the other at the Cudjoe Key Electrical Substation. However, in order to determine if varying heights affected output, both were installed at the Cudjoe site so that all other factors could be considered equal.

One turbine is installed at a height of 57-feet, with the total height of the installation being 63-feet from the ground to the tip of the highest blade. The second turbine is installed at a height of 30-feet, with the total height of the installation being 35-feet from the ground to the tip of the highest blade. The diameter of each turbine from blade tip to blade tip is 12-feet.

The maximum output for each turbine is 2,400 watts and can be achieved at a wind speed of 29 miles-per-hour (mph). The minimum wind speed required for the turbines to rotate is eight mph, below this the turbines will not rotate. Energy generated from the turbines will help offset the energy used within the substation for cooling and lighting equipment. The system was not designed with a battery back-up for energy storage.
