MANITOULIN ISLAND—As evidenced by the large barge in the North Channel or numerous cement trucks headed to and from the Green Bush, construction is well underway on the McLean’s Mountain Wind Limited Partnership’s (a joint project between Mnidoo Mnising Power General Partnership Inc. and Northland Power Inc.) wind farm. The Expositor met with site manager Stan Stret last week for an interview and a first hand look at the construction of the 24-turbine wind farm.
“Right now there are a lot of elements of the construction going on,” began Mr. Stret. “We have completed six of the cement wind turbine foundations, while other sites are in the process of being excavated and some are placing the rebar.” Mr. Stret explained that the foundations are created in four main steps, which include the excavation of the site, placing of the rebar, the pouring of the cement foundation and backfilling the foundations. “The foundation is made of up 40 tons of rebar and the concrete pouring overtop takes around six or seven hours,” added Mr. Stret, as he pointed to one of the large structures.
“The in-water trenching is also taking place right now in the North Channel,” continued Mr. Stret. “They are trenching to the depth of 10 feet to bury the marine cables that will connect the substation to the switching yard at Goat Island.”
Mr. Stret took The Expositor to Goat Island, showing the grounds that will eventually house the switchyard, isolating the turbines from the grid. “There will be a substation on Manitoulin that takes the 34.5 KV that the turbines produce and sets it up to 115 KV that will then be able to tie into the existing 115 KV transmission at Goat Island,” explained Mr. Stret.
