Just seven months after the installation of their first wind turbine, Prehn Cranberry Farm has their second Endurance wind turbine installed.

Vancouver, BC August 13th 2010 - On July 20th, only seven months after installing their first wind turbine, the Prehn Cranberry Company installed a second Endurance G-3120 wind turbine on their property.

Installation of these turbines originally began because the owner, Dr. Fred Prehn, wanted to make an environmental statement. It was Dr. Prehn's desire to alleviate the environmental footprint left by his company's alternate forms of energy production.
Based on the average wind speed of 12.2 mph, each turbine is expected to produce 85,000 to 100,000 kWh per year. The power produced will help cover the electricity requirements for Dr. Prehn's shop, an employee's home and the new high-energy-consuming water pumps that have been installed on his farm.
"We were eager to install one of these last year, and now we have installed two! They are well-designed, durable machines, and the 30-foot blades make the turbines suitable to lower wind speed environments, which are common in Wisconsin. We expect to see these turbines become popular with farmers, schools, and manufacturing facilities," said installer, Ry Thompson, of Seventh Generation Systems.
"This sale to Dr. Prehn represents another key milestone in the deployment of the G-Series turbines throughout North America and to Endurance as a whole. Dr Prehn purchased one of our prototype production units and used it for a period of time. This enabled him to establish the turbine's value to his company's operation. Once Dr. Prehn established that value, he then ordered another unit, to become the first multi-turbine install of our G-Series product line. A key element of this turbine's design, which led directly to its sale, is its ability to be specifically rated- in this case, up to 40kW from 35kW - in order to meet local interconnection standards and achieve optimum energy output. Dr. Prehn's validation of the G-Series turbine makes us confident in our ability to find similar customers," stated Kevin Heaney, VP of Sales and Marketing, Endurance Wind Power.

On August 10th, 2010 the Prehn Cranberry Company hosted the Wisconsin State Cranberry Growers Association summer meeting, where the theme was renewable energy. It was a great opportunity for Dr. Prehn to make his environmental statement! The attendees were able to observe the two turbines on-site and witness the value it has brought to his cranberry farm.
