Remote Power Solutions
From stand alone beacon lighting to village power, we have your remote power solution covered. Bergey Windpower has well over two decades of off grid power experience with projects all around the globe. Our turbines have no required service and are ideal when high reliability and performance are of critical importance. If you can provide latitude, longitude, peak power, and daily kWh loads we can design your system. Simple system designs are typically free of charge while more complex systems include a 1% design fee that’s forgiven at the time of sale. Regardless of where you are Bergey Windpower has a solution for your off grid power needs.
Turbines for off-grid homes
Properly designing an off grid system requires careful thought and consideration. Efficiency is of critical importance. BWC has the experience to help you achieve your goal.

Example Project: FAA Navigational Beacon
Chandalar Lake, Alaska
The U.S. Federal Aviation Administration (FAA) operates an aircraft navigation beacon at Chandalar Lake in the Brooks Range of northeast Alaska. The site is very remote and is accessible only by air. Previously, the site was powered by diesel generators, with all of the fuel having to be flown in. Early in 1999 the FAA began looking into alternatives to both flying fuel in and upgrading their diesel generation facilities to new stricter environmental standards. BWC assisted the FAA and their consulting firms in looking at various system alternatives ranging from 20-100% renewables penetration.
After deciding on an all-renewables system in the late spring, the FAA was allowed to “sole source” the equipment from BWC in order to use the short Alaskan construction season in the summer. The system consists of two Bergey 7.5 kW turbines on 30 m (100 ft) guyed-lattice towers, a 5 kW solar array, a 48 VDC sealed battery bank, switchgear, and two Trace sine wave inverters.
The logistics for the project, which were handled by the FAA’s construction contractor Montgomery-Watson, were quite difficult. For example, the permafrost and site conditions precluded on-site concrete pouring so the wind turbine tower anchor blocks had to be pre-cast in Anchorage and flown via C-130 to Chandalar Lake. BWC assisted Montgomery-Watson with the equipment installation and commissioning in August 1999. The FAA considers Chandalar Lake a pilot project and hopes to replicate it at other off-grid FAA facilities in the coming years. They have already purchased two additional smaller systems for other Alaskan sites. Partial funding for the project was provided by the Federal Energy Management Program (FEMP), which is administered by US-DOE
