Hi Derek,
How are things? It has been a while. A Beck operator I used to work with ask if I knew the location of the control room photo at the top of your Ontario Electricity History page. I pointed him to this page https://www.atlasobscura.com/places/kelenfold-power-station. Any reason you used that photo rather than one from Beck 1 (other than it is very impressive)?
A second question. Peterborough Utilities Inc. say the London Street GS #1 was built around 1915 (https://www.peterboroughutilities.ca/en/pui/waterpower.aspx) but you (and the Ontario Water Association) say it was built in 1884, which makes it perhaps the oldest ac generating station in North America. Where did you get your info? There isn’t much out there for ‘the oldest hydro station’.
Thanks,
Mark
Hi Mark!
I’m doing great thanks, and I hope you are as well!
I’ll try to answer your questions as best I can 🙂
The photo I used for the History of Significant Events was from a source that allows use of the image under Creative Commons license. My website is non monetized so I don’t post images that cost me to use them. It wasn’t until several years later that I found the National archives photos of Beck 1 and explored the copyright implications of using them. So it was just a matter of timing and I may indeed change the photo to SAB 1 at some point, especially if it would be more meaningful to readers. I do update the events list about once a year.
As for the in-service dates for the Hydro stations, I’m pretty sure I got that one from the Ontario Water Power Association along with many of the others. There are multiple reference dates for in-service dates of generating stations and I have tried to pick the most credible ones for the events listing. I’d be happy to change it if it’s inaccurate, but I’d need a solid lead on a source. Thank you for the link to Peterborough Hydro! I’ll look into it.
I think there is more than one station with claim to being the first in NA…like in Wisconsin and Michigan. They seemed to start appearing on an industrial scale around 1880, but very tricky to verify.
Cheers
Derek
Two Hydro plants that should be added, both of which are on the Montreal River in the Temiskaming District
Fountain Falls which came on line in 1914 i believe
Upper Notch which came on line in 1932 I believe
Both plants were flooded out when the Lower Notch Dam was brought on line in 1971
As a child I lived in the colonies located at both of these plants, as well as at Hound Chutes where I was born.
My dad’s father worked on the construction of the dam and plant at the matabitchuan, then served as a dam tender until he retired.
My mother’s father worked at the Matabitchuan as well from 1935 until he retired. He was the plant manager there.
Nice to see this list of plants
Thank you for the historical information Robert!
What an incredible piece of history, thanks so much for sharing!
None of my sources have information about these stations, however if I broaden the search it’s clear that they were on the Montreal River and operated for decades.
I have included them on my list with a credit to you as a source.
Regards
Derek
You certainly have I fairly detailed history of the generation aspect of the Power System in Ontario. Enjoyable read. My first job in the electricity sector was at Chaudière #2 and #4. Zero automation when I was there. You said it was near Ottawa, it is actually in Ottawa just a couple kilometres west of Parliament Hill. I have pictures if you are interested. You should also add the Blackout Aug 14, 2003.
Thanks for taking the time to read the post and provide feedback Allan!
I have revised the Chaudière entry and added references for the Ontario blackouts of 1965 and 2003.
I would be very interested in any photos you may have that you would be willing to have posted to the blog in future articles!
Regards
Derek
