150 kW Battery Energy Storage System Installed In Canada To Prove That Batteries Can Stablize Grid

NOV 29 2015 BY MARK KANE 24



Ryerson University in Toronto, Canada announced the launch of a new energy storage system located at Church and Dundas – “We’ve got the power“.

150 kW lithium-ion battery (1.1 MWh capacity) from Electrovaya, enclosed in a big, metal box, will be used for demonstration of grid stabilization in a one-year pilot project.

“The Centre for Urban Energy (CUE) at Ryerson University is testing this home grown battery system in collaboration with Toronto Hydro to prove how off-peak electricity can be stored. In addition to providing a learning opportunity for CUE researchers and students, the one-year project could have long-lasting impacts on energy storage in Ontario.”

Bhanu Opathella, post doctorate research fellow at CUE said:

“From just this battery, you could electrify 150 houses for four hours.”

“It is going to prove that batteries can be used to correct problems in the power system. This can include voltage fluctuations and power mismatches: we have a lot of demand for energy in the daytime, and a lot of wind generation in the nighttime. Generally, peaks demand occurs from 6 p.m. to 7 p.m. when solar generation is also minimal. When energy generation is high, we can store it in batteries; when the demand is high, we can use that power.”

“The Ryerson campus offers a rare chance for research of this nature to be conducted in an urban setting. “In a rural setting, we can use many technologies because the space is almost unlimited,” said Opathella. “Here, we’re in a limited space, but on the other hand, we have a lot of high-power demand. This is a uniquely good test case: in a highly congested environment, how to manage such a demand for power?”

Is it a 150 kWh or a 150 kW battery pack? Given that Opathella claims it will be able to provide electricity to 150 houses for four hours, a 150 kW pack seems more likely (that would put average electricity consumption at a reasonable 1 kW, rather than a really low 250 W…).

Then it is a 600 kWh pack, which also makes more sense given its physical size.

Source says 150kW battery pack.

Hey Joel,

Sorry Mark didn’t make that clear. It is a 150 kW pack, capacity is 1.1 MWh.

/story updated to reflect

It seems this is a catch hole that work many time. Energy or power, is that so hard to differentiate?
I guess it is.
From EV enthusiast, it’s pretty strange anyway.

Nice catch Joel.

I also was confused by the size and ratings.

Either way, Tesla’s PowerPack appears to be more power and energy dense than this product.

That is bigger than the model s!

13 times bigger to be exact…

It would be interesting to know how much a battery like this costs and how much energy it can store during its useful lifetime. That would give an indication of the additional cost for power stored this way.

I don’t know about this system but most battery systems (note *systems*, including the air conditioning, container, racking, power electronics, control system and grid connection, etc.. not just the cells or pack) are working out as being around $1000 /kWh and the price to store 1 kWh is anywhere between $0.2 to $0.5 over the life of the system. Lifetimes are typically 5000 full cycles which is almost meaningless as the high cost per cycle means that you are unlikely to completely fill it and then run it down to nothing. I find this system pretty fascinating as they have gone for a very small power and a proportionally large energy storage. This is interesting as it suggests that it will be filled over a long period (7.3 hrs) and then discharged over that same period, perhaps they’ll just run it charging and discharging in a window (i.e. never fully charge or discharge just let it drift in a charge window of say 40-80%). This is unusual as most battery systems are configured to charge/discharge in 30 min. They don’t ever do this but they are very much more designed to charge discharge over shorter time periods.

1.1 MWh capacity . . . damn! That is big. California needs some of those to help with the “duck’s neck” issue. (The fact that as the sun goes down thus reducing solar PV, there is a large increase in demand for electricity as people come home & cook dinner. )

1.1 MWh is only a little more than four PowerPacks. I’m surprised it is even mentioned here.

I am trying not to be overly negative especially about Tesla and the associated song and dance around the organization but really?

Elon Musk appearing on the Simpsons or Big Bang theory is news but this isn’t?

BOB was news, but it was 32 MWh in 2010. It’s going take more than 1.1 MWh to get me excited today.

“1.1 MWH – that is BIG!” What is this? A JOKE? 1100 kwh – so enough to charge 10 model S’s. 150 kw? Ok so enough to charge ONE model S at 135 kw (assuming Tesla’s 135 kw charger OUTPUT doesn’t require more than 150 kw INPUT). Or about 1/10 of a car at the rate Priusmaniac wants. Of course, a SuperRural area like DUNDAS street in Toronto I’m sure wont even begin to notice the difference. Maybe at 3am when all the lights are off. This is a really poor area for a trial since the battery is so relatively microscopic. And 150 kw? About what a very small supermaret like Aldi’s , Whole foods, or Trader Joe’s uses in the summer time. But if it allows alot of pseudo-PhD candidates to write a bunch of blather to get their Doctorates, I suppose it will be of some use, at least for the careers of those concerned. For comparison, 100 years ago (YES 100), substations in the downtown Buffalo DC network could supply 20,000 amps at 250 volts for 4 hours. This was typical of battery backed-up Downtown areas all across the USA. Buffalo had 10 such substations (YES… Read more »

Interesting – since Electrovaya says how great their batteries (cells) are – but at 150 kW Output – it would about match the 150 KVA Transformer feeding our small apartment building with 12 residential units and 6 Commercial units split into – Dentist (1 unit) Laundromat (2 Units) and Rehab Centre (3 Units)!

Here is another story from Electrovaya – for Con-Edison:
Electrovaya to Deliver Portable, High Capacity Battery Storage System to Con Edison for Clean Energy Grid Support –

Yeah, those things are a good match for COnsolidated Edison and NY CIty. Since COnEd usually has things blow up or burn out on them catestropically, it will be good to have a few ‘containerized’ juice boxes around so at least the Locals Have SOME juice to charge up their cell phones, or maybe run the water pump to the higher floors of an apartment building.

One of the supposed advantages of an Ac Network (mimicing the old DC Network) was that any one failure wouldn’t kill the juice. Unfortunately, ConEd has the habit often of just letting more and more junk fails, until the strain is too great for the remaining transformers, and they all go out with an avalanched BANG.

So, because of their incompetance, COntainerized juice boxes will be a big benefit in the future.

At 31 1/2 cents/ kwh 24/7/365 for residential rates, its nice to know your confiscatory rates are paying for something. Or did ConEd manage to get NYS taxpayers to fork it over?

Yep, Yep.


The $0.315 rate is an average price for the year. The actual rate varies, and often jumps in the winter when there is a great demand for and a shortage of natural gas for power plants.

Here is a news story of a winter electric rate price hike:


Here is another exploding manhole new story. It happens all the time.

Sometimes, these exploding manhole covers fly though the air and end up hitting someone in the head.

“Electric Hummer”?

FYI Thats nothing new. PJM in US already has a frequency regulation market which employs fast response (around 1MW/0.5 MWh) batteries for grid stabilization. Its already proven. So whats special about this system?

It does correctly state the peak hour of 6-7pm. However, what can we do to reduce that peak hour? Is it even possible? That is “dinnertime” – when we turn on lights in the home, power up the oven or restaurants are working hardest.

Can you image if we had to change our ways and culture rather than buying even more products to “smooth out” our energy demand curve. Could we get up earlier, eat larger meals mid-day, snack in the evenings and convert more of our lighting to LED?

Don’t forget that batteries help but they also are an energy user. You lose energy when charging and discharging batteries – as much as 20% of it. In my own EV, I put in 13 kWh and draw out 10.4 kWh. so, that is over 20% lost. We will need to produce a bit more energy on the grid to supply the power to battery subsystems.
