Severe weather damages Grand Bend area turbine

Calling in sick today.
Severe weather rolled through south-western and southern Ontario yesterday, including damage to homes and even a tornado sighting near Shelburne.

We have a report of a damaged wind turbine blade on a machine at Shipka, near Grand Bend.

In spite of Energy Minister Bob Chiarelli’s recent pronouncement that renewable power sources would prevent blackouts during storms, about 50,000 homes lost power at some point during the day.

Just goes to show! What does HE know!

Oh come on now, that’s just a fluke.

Nearby at Grand Bend last night during the storm, straight line winds were reported at 110 km/hr. How far would the toxic particles debris from this blade have been scattered and, in so doing, contaminating nearby properties?

Looks like the blade was shredded?

Cat.2 tornadoes have occurred before in Ontario. Some amazing storm cloud photos were taken across Ontario of this weather event.

Due to Ontario building codes, structures survive better in these severe weather events here compared to structures in other parts of North America.

On radar, yesterday, the storms were almost in a line from north of Chicago all the way into Ontario.

How well did the new radar system work that was developed to accommodate a wind developer in this region?

Should be F 2 and not Cat. 2 for tornadoes.

Well, probably that without wind turbine, more home could have lost power. They definitely play a large role in today’s grid stability, and this will increase event more as grid code requirement adapt to latest converter technologies.

Regarding the toxic particles, blades are made of wood, glass (fiber) and epoxy. Nothing toxic such as what come out from coal, gas or nuclear power plant… Chunk of blade will probably fly over a few hundred meters, but if the wind farm owner is doing a proper job, they will pick them up.

But I agree that blade collapse such as this one are not so good looking… Probably winds too strong for the blades!

The effect of severe storms is that power lines are down, which results in power outages. Despite the MInister’s assertion to the contrary, if the lines are down, power is out—doesn’t matter if the source is hydro, wind or hamsters in wheels.

We often have blackouts but since the wind turbines came on line, we have brown outs instead. This caused our battery backup on the sump pump to disengage resulting in the motor burn ing out. We had water in the basement for the first time ever and we had to buy a new sump pump.

Hello Ag,

the purpose of your UPS is to protect you from both black and brown out… However it is possible that the battery of your UPS is too old. This happened to me. One way to test it is to disconnect the plug with i.e. a 60W lamp ON. it should stay lit for at least a few minutes (depend of your UPS model) after you unplug. Usually, after 5 years you should replace the battery, or even after 3-6 months if you leave the battery or UPS on a shelf without charging it.

The turbine blades are huge. Epoxy and fiberglass are very strong materials. Wirh a wind strong enough to destroy a blade, I expect pieces travelled a few hundred meters to say the least.
I had an ice throw hit my home from a turbine of ~ 400 meters away. It sounded like a bomb went off when it hit. At first, I thought the chimney had fallen down. Upon observation, i noticed the ice shattered upon impact. Can you imagine being hit by something as a chard of ice or a piece of blade?
In the early years of turbines in Ontario, it was reported a broken blade stuck vertical into the ground; just as I have found large branches of a cottonwood tree on my property after a storm. This turbine was very quickly repaired and kept out of the media.
Would the company or the land owner hold an insurance policy on an incident as such? It should be a requirement of both parties mentioned.
