Owner: City of Ellensburg

The objective of this project was to demonstrate a variety of different wind machine technologies (both vertical and horizontal axis). The Project is located in Ellensburg, WA, on the west edge of Rotary Park adjacent to Interstate 90.
The scope of work included excavation, concrete foundations, turbine assembly and erection, coordination with the City of Ellensburg for metering and connection to the local electric utility grid, electrical service equipment, grounding systems, and AC Inverters as required. Burke Electric provided the (4) following wind turbine systems:

Energy Ball V200 2.5 KW Wind Turbine
The Energy Ball V200 is an artistic spherical wind turbine with 5 rotor blades which was installed on a 40’ tall mono-pole. Its patented round form is particularly pleasing to the eye, yet is silent to the ear. The turbine comes equipped with a WindPower Inverter which delivers power directly to the utility grid. The Energy Ball V200 is designed in Holland and manufactured in the USA.

Honeywell WindTronics WT6500 2.2 KW Wind Turbine
The WindTronics Wind Turbine is a novel electric generator. It consists of a central wheel made up of an aluminum rim, stainless steel spokes, and an aluminum hub which is attached to a 36’ tall mono-pole. Two ceramic bearings are used to attach this wheel to the center shaft of the turbine. Custom shaped glass-filled nylon blades are attached to the spokes of this wheel. Permanent magnets are affixed to the tips of these blades at the rim of the wheel. The wind flows through this wheel and interacts with the aerodynamically designed blades to induce a rotational motion in the wheel around its center hub. The placement of the permanent magnets at the blade tips produces the needed high speed motion without the need of any gearing mechanism.

Skystream 3.7 KW Wind Turbine
The Skystream 3.7 is a wind powered generator containing an integral AC power inverter which was installed on a 45’ tall mono-pole. The Skystream 3.7 is manufactured by Southwest Windpower located in Flagstaff, AZ. Burke Electric partnered with Central Wind Energy in Ellensburg, WA for the installation.

Windspire Energy 1.2 KW Wind Turbine
The Windspire wind turbine is a vertical axis wind turbine manufactured in Reno, Nevada. Power is generated when the wind blows against the vertical airfoils causing them to spin. The turbine was installed on a 30’ tall mono-pole.
