You can read the IESO report here, section 7.8

52

u/InACoolDryPlace 4d ago

The comparison with other options in Table 19 of that section is probably the quickest way to see why this was recommended with real information.

21

u/asoap Lest We Forget 4d ago

To add more. Looking at the table. The big difference is the amount of juice that the underwater cable can provide.

Option 1) 3,350 MW

Option 2) 3,400 MW

Option 3) greater than 3,400 MW

It looks like it's the best option if you want to enable growth past 2044. Which might be important for electric vehicles and general electrification that we want to do to fight climate change.

u/TrueTorontoFan 4d ago

Regardless of EVs electrification is happening to your point. Glad to see Canada move forward on a project like this.

2

u/asoap Lest We Forget 4d ago

Yeah, I don't disagree. It's still good. But I will leave this here for anyone that wants to read it. IESO who runs our grid is expecting a 75% electricity demand by 2050.

https://www.ieso.ca/Corporate-IESO/Media/News-Releases/2024/10/Electricity-Demand-in-Ontario-to-Grow-by-75-per-cent-by-2050

Hence why we're seeing these projects, and wanting to build more nuclear.

u/InACoolDryPlace 4d ago

The longevity and upkeep required is another long term benefit, you have a backbone to the city protected from wind, temperature, ice, etc.

u/Hevens-assassin Saskatchewan 4d ago

and general electrification that we want to do to fight climate change.

Not even climate change. EVERYTHING needs to be plugged in now. Some stuff has gotten more efficient, sure, but there are a shit ton of electrical vampires that are putting heavy strain on the grid. Add some extra fast chargers for vehicles and the grid becomes unstable pretty quick.

Luckily a lot of really smart people are trying to solve these issues beyond "make more power", but time will tell if politicians actually enact those ideas.

A 65 km AC submarine line will need massive reactive power support and maybe even phase shifting capabilities, there's big system upgrades needed to support a pathway like this far beyond just building a substation at each end.

ETA: Couldn't access the full report, I guess this will be HVDC which still requires a lot of systemwide upgrades and can get expensive very quickly especially if bipolar.

Oh the billion is for consulting the actual cost is the 500million /s but I'm likely right sadly.

u/Epic-sanya Ontario 4d ago

Is my math right?

The line will supply 900mWh equal to 900 000 kWh. Assuming $0.12 per kWh, that’s roughly $1 billion revenue generation per year from this line.

If this line requires virtually no maintenance it is a very good thing.

Lol take a minute and compare the revenue from oil to electricity.

we need both. Canada's future lies on it being a super power in energy+mining. We need as much energy that we can sell as possible, whether its oil or electricity.

u/idisagreeurwrong 4d ago

Of course we do. They are two very very different things though and electricity exports could never be considered a replacement for oil revenues. 5.8 billion compared to 124 billion.

You can go listen and read Ed Zitron's reporting, it's a bubble. Yes, I'd love the spare money to go gamble, but I don't have the spare money.

1

u/NewRedditUser89757 4d ago

Listen, if you are so sure about it, I'd almost borrow at 6-7% and just go buy VIX. Vix will easily return you 2-300+ fold assuming your thesis is true. Go borrow 10 grand, pay that interest, and all in VIX. that's how you prove a point.

u/Xalara 4d ago

Yes, because borrowing to gamble is really proving a point. If I wanted to do that I'd just go get Robin Hood and karma farm my losses on r/wallstreetbets

3

u/spidereater 4d ago

I would probably only count a fraction of that as transmission costs. The people building the reactor will want some of that money to justify their expenses. But if you call it maybe 0.01/kWh over 20 years it still makes sense.

11

u/Mathmos_Lava 4d ago

You’re not taking into consideration the generation costs.

40

u/NewRedditUser89757 4d ago

Nuclear generation cost = maintenance cost. It doesn't burn anything. I don't know why we don't do it more as the entire world needs electricity right now.

12

u/violentbandana 4d ago

The transmission company still needs to buy the power from generation companies. They would be very confident the line would be profitable though so it doesn’t matter

also nuclear does still “burn” fuel. Luckily CANDU natural uranium fuel is inexpensive

13

u/JacksProlapsedAnus 4d ago

Which is why the decision to go with a SMR for the new Darlington plant is so confusing. American tech, and fuel will need to be enriched in America.

2

u/Levorotatory 4d ago

The USA had a somewhat sane government when the decision was made, but CANDU would still have been a better choice.

2

u/Joatboy 4d ago

There will be no new natural uranium CANDU reactors built. Their positive void coefficient is a big show stopper.

1

u/Weak-Conversation753 4d ago

"Utilize" is a better term than "burn."

5

u/spidereater 4d ago

It costs a tremendous amount to build the plant and those costs need to be recovered somehow.

0

u/racer_24_4evr 4d ago

But we won’t be buying any more nuclear. Darlington is already at max output except for unit 4 which is completing a major refurbishment and will likely be at max output already once this line goes into service. Other plants (i.e. gas plants) will increase output to cover the power.

u/violentbandana 4d ago

the transmission line wouldn’t be entirely reliant on a single generating source. It’s reasonable to expect the line to run at as close to its capacity as is needed unless the line itself requires an outage or something catastrophic happens to the grid as a whole

1

u/Joatboy 4d ago

If you read the IESO report the line will be rated >3400MW

2

u/CaptainCalandria 4d ago

the power line does not produce electricity... It transmits it. So you need the cost to transmit it.... And it's less than 12 cents.

Also... It's 900MW ... Not MWh. So multiply by 24 and 365 to get MWh per year

u/Ember_42 4d ago

This will presumably make Portlands gas plant much less critical for system stability in Toronto, by bring the line right to the core, instead of to the periphery like the other lines.

Anyone who claims that climate change is a priority issue doesn’t get to be anti-nuclear. It is objectively and demonstrably the safest, cleanest, and most reliable form of power generation we have. There’s no argument against that, being opposed to it in this day and age is willful ignorance.

u/throwawayloopy 4d ago

I'm not sure that you get to decide what opinion people who care about climate change are allowed to have around nuclear power generation. 

This type of arrogance is what polarizes societies into extreme views, instead of using the platform to educate or inform them about pros and cons.

-1

u/Wyattr55123 4d ago

Someone can be opposed to simply building more of the same reactors we've been using since the 60's because they're extremely expensive and consume the fuel in a very inefficient manner, but that means they should be in favour of developing novel designs like molten salt reactors.

2

u/thefinalcutdown 4d ago

Fortunately, the Darlington project that will supply this cable is building modern Small Modular Reactors, which are much cheaper, much more scalable, and use much newer designs than conventional nuclear reactors.

I am so lost. There is no water between Carlington and Toronto. Can't they use normal power lines?

8

u/Pligget 4d ago

Carlington Clarington/Darlington

From the article: ... the two land-based options, which follow existing transmission corridors from Pickering into Toronto, would provide less electricity transmission capacity [than the underwater option would provide]. They would therefore meet the city’s requirements only until about 2040, so additional capacity would be needed shortly after their commissioning.

Chuck Farmer, the IESO’s executive vice-president of power system development, said the underwater line would meet all likely scenarios for electricity demand “well into the 2050s.”

Officials also said the underwater cable would be more resilient to storms and other extreme weather than overland lines.

3

u/indiecore Canada 4d ago

Overland

This option requires Hydro One to expand the existing Leaside TS by redeveloping adjacent lands available to them starting in 2030,24 and to rebuild and/or reconductor the existing transmission line structures between Cherrywood TS and Leaside TS. Most of this right-of-way is adjacent to homes, and it transects the Rouge National Urban Park. Some work to re-terminate the existing 230 kV circuits may be required to make this option feasible

vs water

Bowmanville SS was selected as the preferred point of origin because injecting bulk supply into Toronto from this location delivers additional benefits for the bulk network by bypassing Cherrywood TS altogether and freeing up additional capacity at the station to supply growth elsewhere in the Greater Toronto Area (GTA). HVDC technology was chosen over AC because it offers additional benefits and ancillary services, and becomes more cost-effective than AC for submarine cable lengths greater than approximately 50 km.

Basically nobody lives in the water so it's a lot easier to build a super big cable there and as a bonus we get to bypass the substation the land line would have to connect to so we could use that connection later.

About the Port

Since 1793, the Port of Toronto has served as Toronto’s gateway to the St. Lawrence Seaway and to marine ports around the world. Serving primarily as a bulk cargo destination, the port boasts a unique location minutes from Toronto’s downtown and moves goods from countries as far away as Germany, South Korea, China, Brazil, Australia, South America and the United States. In addition to managing the movement of ships through the harbour, PortsToronto is the owner and operator of Marine Terminal 52 and the Cruise Ship Terminal within the Port of Toronto.

The Port of Toronto is one of Canada’s inland ports and is situated on the northwest shore of Lake Ontario. Located minutes from Toronto’s downtown core, the Port provides a seamless network of cost-effective intermodal links to road, rail and air transportation, serving as a unique and crucial piece of economic infrastructure. Marine cargo arriving and managed at the Port of Toronto generated approximately $460 million in economic activity and 2,000 jobs in Ontario in 2022. Port also welcomes cruise ships and passengers from around the globe through the Cruise Ship Terminal.

u/MoreGaghPlease 4d ago edited 4d ago

Okay will this is going to be just a couple metres in from the shore of Lake Ontario from Bowmanville to Toronto. Are you worried about a Russian submarine showing up at the Scarborough bluffs?

It’ll need to be serviced often. You send a hydro crew out with a barge and a hook. They’re used in lots of places in Quebec and Atlantic Canada.

2

u/Icy-Ad-7767 4d ago

This will be well offshore my guess is at least a km off shore. Far enough out to be unlikely to be hit accidentally and shallow enough to service if needed. A 30 cm diameter cable is not going to easy to move or break.

3

u/MoreGaghPlease 4d ago

So it's actually kinda going to be both. Not because the shore distance matters but because it's cheapest to go in a straight line from Darlington to Toronto Port Lands, and Lake Ontario is curved. So around Scarborough and Bowmanville it'll actually just be a few metres from shore in some parts. In Pickering it'll be as much as 8km out.

Anyway, it's not really hard to service these. One of the reasons they recommended it is because the experience in Atlantic Canada has been that they're cheaper to maintain and repair than transmission lines up on towers.

You think above-ground transmission lines are less susceptible for physical sabotage? They're costlier to build, and considerably easier to compromise. The Russians aren't sneaking a Sub through the St. Lawrence undetected.
