The 12 wind turbines that are proposed for the Otter Creek Wind Farm, will be significantly taller than wind turbines already erected in Chatham-Kent.
The wind farm, which is scheduled to be built north of Wallaceburg, will have Enercon E-141 turbines.
From the ground to the top of the wind blades, the proposed wind turbines at the Otter Creek Wind Farm will measure 195 metres (642 feet).
By comparison, the world’s tallest wind turbine in Germany is just under 230 metres (754 feet).
Initially 17-20 wind turbines were proposed for the wind farm project. It was scaled back to 12, which Otter Creek officials said was due to public concerns.
Most wind turbines in Chatham-Kent are approximately 155 metres (510 feet) from ground to the top of a blade’s tip.
“The reason why these turbines are a little bit higher and a little bit wider in diameter, is to effectively reduce the use of the number of turbines,” said Adam Rosso, who is Otter Creek Wind Farm’s director of development.
Rosso said by using fewer turbines it will reduce the visual impact, as well as other impacts.
A benefit of the tall turbines is they will produce a higher yield of electricity.
“The concept is that the higher you go, the more smooth-flowing wind they get, the more efficient you’re actually able to produce electricity at that height.”
Even though the proposed Otter Creek turbines are taller and have a larger diameter, Rosso said they won’t be louder, due to less rotational speed.
The proposed North Kent 1 wind farm, which will be located southeast of Wallaceburg, plans to use 113-metre rotor diameter turbines. Otter Creek plans on using wind turbines that will have 141-metre diameters. North Kent will use 3.2 megawatt turbines, versus the Otter Creek turbines which will produce more power of up to 4.2 megawatts.
Unlike other wind turbines in Chatham-Kent, the turbines in the Otter Creek project will use precast concrete in its bottom half instead of steel.
Residents who are interested in speaking with Otter Creek Wind Farm can visit their engagement centre at 216 Nelson St. on Tuesdays from 10 a.m. to 3 p.m. or by appointment.
The wind farm is a partnership of Renewable Energy Systems Canada (RES) and its partner, Boralex as well as Walpole Island First Nation. The total ownership of the project is as follows: RES 51%, Boralex 38.5% and Walpole Island with 10.5% ownership.
Boralex will submit the REA application to the province in the next month or so with a targeted approval for fall of 2017. If the REA is approved, construction would begin in 2018 and commissioning in 2019.
