Saft to provide Li-ion energy storage system for wind project in Saskatchewan

Saft has been selected by Cowessess First Nation (CFN) to design, produce and install a battery energy storage system (ESS) including two Intensium Max 20E lithium-ion battery containers as part of the High Wind and Storage Project near the City of Regina, Saskatchewan.

The Regina project is the first wind power application for Saft in North America. The grid-connected ESS system will help optimize renewable wind power performance by increasing reliability and decreasing volatility by as much as 70% over the 15-year lifespan of the system. Each Li-ion ESS includes a 400 kW Power Conditioning System for use in conjunction with an 800 kW utility scale wind turbine.

The system is designed to harness intermittent wind power and provide a more continuous and predictable output for both on-grid and off-grid applications. The High Wind and Storage Project will also reduce greenhouse gas emissions, reduce electrical production costs, provide more renewable power to the grid and potentially lower electrical rates since the battery can be charged during off-peak periods and dispatched during periods of peak usage.

Saft has demonstrated that this base system can perform wind smoothing and achieve a maximum ramp rate of 10% per minute of the rated power output of the 800 kW wind turbine while also providing up to 400 kWh of peak shaving capability. The flexibility and scalability of Saft’s solution also allows the energy content to be increased in 124 kWh increments up to 992 kWh if additional peak shaving capability is desired.

The installation is scheduled to begin operation in early 2013.

CFN is running the project in collaboration with the Saskatchewan Research Council. The project has received funding from Natural Resources Canada’s Clean Energy Fund, Aboriginal Affairs and Northern Development Canada’s ecoEnergy Fund and the Saskatchewan Ministry of Environment’s Go Green Fund.



And the price is? Wind and solar will certainly be greatly enhanced by storage, but it adds cost and so we can be all amazed by this big battery and love it and everything, but if we don't know the price we don't know whether it is just another goofy denmonstration or whether it has some reasonable real applications. To my knowledge, there is no battery that is truely cost effective for solar or wind. You can certainly buy something that will do the job (it really works), but there is no economic benefit. You get to pay more. And, maybe that's the answer, but that answer is better than no information.


Batteries ( and capacitors ) are employed profitably to smooth frequency and load across small time intervals.
Since you have a sunk cost in a large turbine that makes sense.
What you can't do at any reasonable cost is store enough to cover slack winds over any time of more than a couple of hours or so.

That can be seen by checking our the capacity figures.
The battery is good for around 1/2 an hour at the rated turbine capacity.

So it helps to make up for some of the wild variability of wind, but it doesn't even make a dent on the bigger problem of wind storage to cover during calms.

My understanding is that wind farm operators have been in the position in which they sometimes had to go on the market and purchase power if the wind suddenly dropped and they had sold a block. That purchased power (think gas peakers or paying someone to avoid) can be very expensive.

The price of batteries might be high if you think of them as only ways to smooth out the flow, but if they are allowing wind farms to dodge very expensive purchases then that's a different metric.


"just another goofy denmonstration" can have a large value. It's the early days and the industry is learning what works and what needs to be improved. First generation batteries, like first generation calculators, computers and cell phones are likely to be expensive. But we seem to be able to figure out how to reduce costs once we figure out the end result.


Very hard to compete (economically) with the free stuff that gushes out of the ground forever.. but if you can get free money from the government or eventually stick it to the consumer then its ok for wind or solar power..

People dont mind paying a few more dimes per kWh for green electricity.

Imagine if the shale boom is replicated all over the world, perhaps centuries worth of cheap oil.. maybe


"That can be seen by checking our the capacity figures.

The nameplate rated capacity of the turbine?.. thats crazy talk unless its in a hurricane :)

Still, 30 minutes should be plenty of time to fire up a gas turbine.


"Imagine if the shale boom is replicated all over the world, perhaps centuries worth of cheap oil.. maybe"

I literally detest any suggestions increasing the CO2 content in the already ravaged atmosphere! Are the implications of "Katrina" and "Sandy" insufficient?

As long as only others suffer but oneself is exempted, everything is all right? Eh??


Herm - When you put your straw in the ground and get oil to gush out free forever, be sure to let us know. Apparently Exxon does not know about this, as their output is down.
