Churchill Wild has always been devoted to minimizing their environmental footprint at their remote northern eco-lodges. Now they’re enhancing their environmental stewardship programs even further with the installation of Vertical Access Wind Turbines (VAWTs) manufactured by VBINE ENERGY in Winkler, Manitoba.
The combined power generated by the VAWTs and the solar panels currently in place at their eco-lodges will virtually eliminate the need to use fossil fuels at Seal River Heritage Lodge, Nanuk Polar Bear Lodge, North Knife Lake Lodge and Dymond Lake Lodge. Generators will still be in place for backup power, but the combination of the current solar-panel system combined with VAWTs is expected to provide for almost, if not all, their power needs in the future.
“The beauty of it is that we have a battery storage system,” said Mike Reimer of Churchill Wild. “The power generated from the VAWTs and the solar panels is stored in the batteries and we draw off of them. And they’re eco-friendly and economical. There’s less noise pollution, less of a carbon footprint and we’ll be paying substantially less than the $1-$1.30 per kilowatt it costs for diesel generated power.”
The VAWTs were invented by Barry Ireland about six years ago and refined by an engineering team. Their showcase installations include the Dr. David Suzuki Public School in Windsor, Ontario, Canada and Wayne State Universityin Detroit, Michigan, but the rugged VAWTs were also designed to work in remote northern locations. “They were originally designed to work on smokestacks and silos,” said Ireland. “We had to build them so that the center wouldn’t rotate. We also had remote communication towers in mind when we built them. Many of those towers are powered by diesel and the VAWTs cut costs by quite a bit. That also means they will be popular with many northern lodges and outfitters.”
VBINE is currently working with Canadian Solar on a combination wind/solar solution that will work for northern communities. “VAWTs are generating a large amount of interest because of the significant cost savings that can be realized,” said Ireland. “And the fact that the big windmills won’t work in the north. They ice up, they have too much vibration and they won’t go into the permafrost. The VAWTs are the only ones that will work up north.” VAWTs mount easily on existing buildings; they’re only two meters in width; they’re quiet and they’re suitable for grid tie-in or battery storage. And because of the vertical design, VAWTs can take wind from any direction. They start generating power at wind speeds of 1.2 meters per second and run 24/7 generating 5 kilowatts of power with a 25 mph wind. They have a permanent magnet generator with two long-life bearings, no drive shaft and no slips springs or brushes. The lifespan of the VAWTs is estimated at 30 years with very little maintenance. Their sleek design also minimizes interference with wildlife.
The first of the Churchill Wild VAWTs were hauled up to Seal River Heritage Lodge last week via CAT train (caterpillar pulling a freight sled) across the Hudson Bay sea ice, which is still about six feet thick.
Hauling tons of freight across the Hudson Bay ice in -20 degree weather is actually better than doing it at 0 degrees. The ice can get sticky and wet in warm weather, making for dangerous conditions. While there is generally no immediate danger from polar bears, which are still further out on the ice filling up on seals before the ice melts, the weather can still cause problems.
“The wind chills can get to as low as -40,” said Reimer. “And there’s always the possibility of blizzards, flooding sea ice and slush holes. CATS have actually gone through the ice on a couple of occasions.”
The trip takes about 15 hours from Dymond Lake Lodge to Seal River Heritage Lodge and Churchill Wild utilizes one of their two CAT track-type tractors, 1956 and 1972 models built by Caterpillar. But how fast does that CAT really go? “About two miles an hour downhill with a tailwind,” said Reimer.
